Overclocked my E8400 to 4ghz, is this safe to run?

[Coldsweat]

I've been fussing around with my new rig for about two weeks now trying to get it stable at 4ghz or beyond. It seems I've finally done it, I'm just scared, is my voltage too, high?

I think my rig is listed in my signature but if not, here's what I'm using...

PSU - PCP&C Silencer 750
MOBO - Gigabyte GA-X38-DS4 - linked is the EX38 as Newegg no longer carries the X38
CPU - Intel Core 2 Duo E8400 Wolfdale
CPU Cooler - Xigmatek HDT-S1283 with Arctic Silver 5 Thermal Paste
RAM - Corsair XMS2 4GB(2x2GB) Dual Channel PC2 6400
Video Card - BFG GeForce 8800GTS (G92) 512MB
Primary HDD - 2x WD 150GB 10K RPM Raptors in Raid 0
Storage HDD - Seagate Barracuda 7200 RPM 500MB
DVD/CDROM - ASUS 20X DVDR Burner
Case - Apevia X-Pleasure Black ATX Full Tower
OS - Vista 32bit

Alright, I've been reading all over the net about people using this board and processor and hitting 4ghz on air at vcores of like 1.28 and 1.34 and stuff like that. I could not for the ever living life of me get mine to even boot into windows at that low voltage. I had 3.6ghz Prime95, Orthos and Memtest stable at 1.34 volts and not a fraction of a volt less. So, I got frustrated and decided screw it and just went for it. Once I got up to about 1.45v it started booting into windows and "appearing" stable. I got it stable at 1.5v. No matter what other voltages I tweak, it doesn't make any bit of difference. I can leave everything on normal/default/auto except for my vcore, I have to manually set it to 1.5 to get it to run at 4ghz.

Currently, I'm 445 FSB x 9 for the 4ghz, running my memory 1:1, 2.00D which puts it at 890mhz. I have also successfully been able to run it at 500 FSB x 8 for the 4ghz and my memory at 1000mhz, 1:1, 2.00D. I've tried maxing my FSB voltage, I jacked my RAM up to +.3.5(didn't dare go higher), I juiced my chipset voltage all the way and I've tried every setting in between and none of them make a difference as far as I can tell, the only thing that matters is the core voltage set to 1.5. On CPU-Z it shows it at 1.440 with Orthos running, without Orthos it shows it at 1.456 - 1.472 V. Do you guys think this is safe to run all the time or should I drop it back?

As far as Temps go, Core Temp idle shows about 50-52 C after 30 minutes, under load it goes up to 70-71 C most of the time, sometimes spiking as high as 75 C but I've never seen it go higher.

My bios temp, whenever I reboot into it, I've never seen it higher than 21 C, I set the threshold at 70 C and the alarm has never gone off.

The Gigabyte software, EasyTune5 Pro. It lists 3 columns, Voltage, Fans, Temperature. In the voltage column, two more columns, Item and V. In Fans, ITEM and RPM, and the Temp colum has ITEM and C/F.
So then it reads out like this
VCoreA 1.490 CPU 1383 System 50/122 - IDLE
+3.3V 3.290 PWR1 0 CPU 24/75
+12V 12.110 System 0
CPU Vid 1.220
Under a load, Vcore row (system?) temp stays the same. +3.3V row, jumps to 53C/127F max - I assume that's got to be my CPU temp.

Then there's SpeedFan...
Idle after 30 min - Temp1 is 50C, Temp2 24C, Temp3 -2C, Temp4 2.
Vcore1: 1.47V, Vcore2: 2.08V, +3.3V: 3.30V, +5V: 4.92V, +12V: 11.94V
-12V: -16.56V, -5V: -8.68V, +5V: 5.13V, Vbat: 3.14V
Under a load temps are Temp1: 50C, Temp2: 53C max, Temp3: -2C and Temp4: 2C.

And if anyone cares, my memory timings are 5-5-5-15. Advanced timings I have not messed with but they are 6-48-13-15-12-4-8-4-6-3471-2T. I ran Memtest overnight and I had the FSB at 540 x 7, so the memory was fine at 1080 with those same timings.

So yeah.. what do you guys think? Can I push this thing further, clock it back? Leave it alone? Work on memory timings? Any suggestions? Tips? Tricks? =D

Thanks in advance to all who respond and took the time to read this.

 

[Tempered81]

If you set your 1.5Vcore in bios down to 1.47, or 1.46 can you still boot?

 

[nullpointerus]

You won't notice the difference between 3.6 and 4.0 GHz in most real-world situations.

However, running at 1.5v constantly will probably shorten the life of your chip and will definitely produce quite a bit more heat. It'll also use a bit more power.

I say clock it back. Extreme o/c-ing is fine, but let's keep it reasonable, right?

I'm in the same boat as you, except for me it's 2.6 GHz @ 1.35v vs. 3.0 GHz @ 1.50v. I could run 3.0 GHz for normal usage, but the chip gets VERY HOT under load, and there's no difference for what I do between 2.6 and 3.0 GHz.

IF your board handles EIST voltage correctly, things might be different...

What is your vcore at idle when EIST/C1E are both enabled in the BIOS?

 

[Coldsweat]

Well, clocked at 4ghz still, my Vcore at idle after just booting up is 1.472 V in CPU-Z.
It shows up at 1.47 in SpeedFan and Gigabyte EasyTune5 Pro shows it as 1.490 with EIST/C1E both enabled. Also, yes I can boot the system into windows no problem as low as 1.41v, it's just not Prime95 or Orthos stable for more than like..oh say.. 5 seconds. When I push it to about 1.47ish it'll stay stable for 30 seconds or so before I get an error and at 1.48 it's the same. 1.49 it went for about 50 seconds or so and then at 1.5.. the magic number, it's stable overnight in Orthos and Memtest.

So I'm guessing my board doesn't handle EIST voltage correctly, but my processor is running at 2.6ghz at idle.

 

[Tempered81]

Whats your temps when priming at 1.5 4000mhz?

what vcore did it take for 500x8 at 4ghz?

Also, go get Everest.

 

[Coldsweat]

Same vcore at 500x8, 1.5. I have not tested it as long, but I let it go on Orthos for almost 2 hours and it was stable at 1.5, but again, not long at all at 1.49 in my bios and I get an error.

As far as temps go again, by "priming" I assume you mean while running Prime95. If that's the case, they are the same as what I posted above unfortunately. I'm not even sure how bad or good those temps are. I've got a solid two weeks of use on this thing now, with shut downs and such, so my thermal paste should be "set" and everything.

I'll go grab Everest right now and run it.

 

[Tempered81]

seeing as though you're kinda new at ocing... Most experts in here are theorizing that above 1.40 actual load vcore for 24/7 operation is dangerous.

this means that your 1.456 vcore is a tad to much according to the general consensus, even if your air cooling provides decent temps. They warn of things like electromigration and chip degredation. things you cant see/smell/etc, yet take effect over time. Just beware that I'm warning you about 1.40Vcore+ since the title of your thread ask's "is it safe"

 

[Xpoc]

My system is stable at 500 x 8 = 4000mhz.
All I did was set vcore to show 1.38v after droop, mch voltage+1, and FSB voltage +1
My ram has the epp profile for the DDR2 1000mhz@5-5-5-15, and works at that no problem.

1.5v isn't worth the time unless you want to fry your chip.

I just ordered the X38-DS4 which will be here Thursday. I also had a RMA request to Asus for my P5E, and they finally got me an RMA number after i have given up on them. lol
So I guess I will end up with both the motherboards that were so hard to choose between

 

[Tempered81]

thats a nice example. I could run 4050mhz at less than 1.3 actual vcore.

 

[Coldsweat]

Yeah I think I'm going to just drop it back to 3.6ghz at like 1.34v. I've got Everest running right now, everything seems stable so far. I got Everest Ultimate 4.20 or something like that, whatever the newest version is. Running the trial though... pretty neat software. Everything it's reporting as far as voltages and tempts, vdroop and such are the same as CPU-Z/CPUID and EasyTune5 Pro, Coretemp and SpeedFan. It's currently stable at 500x8 for 4ghz. 1000mhz on the Ram 1:1.. yay.. I wish I could leave it like this without worry but I'd rather not run the risk of burning up $200-$500 worth of hardware for 400mhz.

 

[Xpoc]

I just leave mine at 3.6ghz because 1:1 is 9 x 400.

I don't have to change any voltages at all for 3.6ghz. except to get vcore at 1.22v after vdroop, and everything else is normal.

I hope to have some good OC'ing with my X38-DS4

Actually in my experience stress tesing components, you can sort of smell when the chips are being pushed past their useful range. It smells like Ozone. Whenever I pushed enough current through a diode to reduce it's useful range it would smell like ozone, so there was a good indication that I had pushed the part to its limit. I'm not saying that you will necessarily smell the chip burning, with the fans and everything, but it is possible.

 

[imported_wired247]

I'm still waiting for a thread or report to pop up with "I fried my e8400. It died at XXXX Voltage. beware"

but haven't seen one yet. Anyone?

 

[Tempered81]

Nope...


I pushed as much as 1.56 actual on mine when trying to prime at 4.5ghz. I've seen over 2.1 Vcore on cascade & ln2 systems.

the 1.4 is "guessed/assumed" safe point. if people are correct in saying 1.4, then maybe in two different chips one could experience problems at 1.38 24/7 while another would have no problems doing 1.48 24/7. It's just that all the chips are different so you never know, and it's best to just follow the guidelines. I think here at AT aigo is pushing 1.57 on water and Yoxxy has 1.57 on his e8500 on phase. I think yoxxy is running it for the sole purpose of seeing if anything goes bad with a 1.57 24/7 vcore.

Thankfully we have people pushing the limits in the name of research.

geeze... how come when i say this... no one believes me and instead believes people who have less overclockign experience?

Its hard to hold a E8400 on prime higher then 4.0ghz. You'll also notice how fast the voltage will scale past 4.1ghz for prime stable.


But yeah, op, if it means anything to you, im on 4.3ghz but its at a very unsafe vcore. 1.57Vcore. But let me be frank, it took 1.42 for my chip to hold prime95 stable @ 4.0ghz. 1.47-1.49 for 4.1 For 4.2 it took 1.51vcore 4.3ghz 1.57Vcore! thats 1.6V in bios!

I dont recomend this setup. Im on water and load temps dont break 50C. It actually sit at round 47-49C depending on ambients. More like if i leave my window open or not.

Its very hard to hold prime in the upper numbers. As i said it scales rediculously high.

Jared DONT give him wrong advice, You havent shown me a 7 hour prime you have no idea how it handles on hardware.

Xpoc Welcome to anandtech, can i see a PRIME95 25.4+ or higher screenie of at least 7 hours. The OP has asking for a prime stable rig, not a windows stable rig! Big difference between the two. Expecially on hardware.

The OP CLEARLY STATES he's having problems holding prime95.

If you guys dont have ANY EXPERIENCE in holdig a prime @ 4.0ghz, I ASK YOU DO NOT POST TO CONFUSE THE OP! You dont know enough if you dont know prime to help him, and giving him wrong advice WONT help him and only make him more confused.



OP for now, try cooling your northbridge with some active cooling. Sometimes that gives you a few minor fixes. Also i hope you did some preping on the board b4 you dropped it in. If you didnt, your going to need to pull your board out and prep it for high end ocing, if you want durabilty in the long run.

Also need some air on your mosfets. Loading up your processor for that long can lead it to overheat. The X38-DS4 is a ultra durable board, however if things get hot, the faullt tollerence on hardware decreases.

 

[Zenoth]

You need to isolate the memory first, always.

I'd put my hands in fire that you've increased the vCore that much for nothing. I'm not saying that it isn't possible, but the chances are very high that your fail-to-boot issues are related to the memory, its timings (once OC'ed) and its voltage. I've never seen a single E8400 requiring 1.5v to run at 4.00Ghz. The maximum I've seen so far is between 1.40v and 1.43v, I can't remember exactly, and that's quite a bad luck, there's a few out there like that, but that's inevitable, some chips do overclock very poorly. But I've seen 4.00Ghz 24 hours+ under Blend Orthos and F@H for three days stable at 1.38v and some times even less.

You have to play with the memory a lot. Loosen the timings, increase the voltage by small increments (don't go above 2.3v for DDR2 unless you're willing to risk damaging it permanently or unless you've got something like a 120mm fan blowing onto the modules themselves from your side panel). For example go from your current 1.5v at 4.00Ghz to 1.48v, go into the BIOS, loosen the timings, make sure it runs at least at 2.1v (the memory), if it fails try 2.15v and then 2.2v and then perhaps 2.25v to 2.60v or so, but try not to go above. Then immediately and only start Memtest86+, don't go into Windows right away. Leave Memtest running for at least one hour (that's about 1 or 2 passes at default configurations, and a good number of passes at test #5 only). Keep an eye on the test to see if it has any errors. Usually after one or two hours stable it means that there's a good chance that it is stable... BUT it doesn't mean that it will be under very stressful applications or even in gaming. It might still give errors later. Your best bet is to leave it run for maybe one or two hours and if there's no errors leave it be for a couple of hours like that, maybe for a total of five or six hours depending on how much time you can afford not to use your system. And so on. You need patience with "proper" overclocking believe me. It took me two weeks to get where I am with mine, two freakin' weeks, and yes I've tested different settings every single days of those two weeks.

Try to play around the advanced timings like Read to Precharge and Write to Precharge Delay and so on (the names might differ from motherboards to motherboards). Isolating the memory first, in my book, is a necessity. Once you know that your memory is stable at given timings, speed and voltages leave it there and use FSB/Memory ratios to maintain your memory at that specific speed or below it, try not to set it above, you can do wonders with a proper memory ratio. It is indeed a possibility that your E8400 is just one extremely rare lemon, but as I said I'd really doubt it.

show me where the "wrong" advice is you buffoon. You for the longest time preached about how great your quad core was, now you're giving dual core advice.

You are really getting on my nerves and i dont have to show you screenshots of shit because you can look at anyone with an e8400 in their sig here and see it reads 4.0 to 4.1

You make no sense half the time anyway. Please quit saying shit like that.

 

[Tempered81]

i think your chip is capable of 4.0 easy; look at what zenoth wrote.

 

[Tempered81]

If you listen to aigomorla, he will tell you that 3.6 is your maximum - unless you put a watercooling setup on it.

you told him to reduce his voltage when he clearly told us that by doing so it wouldnt hold prime. The op is asking for prime stable settings, something which requires a bit of work, and also rock stable settings. Voltage dimming is never considered that unless your going after lower heat output.

If prime fails, then most of the time its one of these things.

1. heat
2. voltage on ram or cpu or nb
3. ram divider.
4. The worst scenario - your chip is a dud, or you have bad hardware.

Neither of which to solutions you recomended. Hence why i am telling people to not participate unless they have experience with prime as a stress tool.

Now the op asked if he should go higher or lower. Its funny how you guys all tell him to go lower in voltage but yet hold the OC the same. Well guess what, if i was the OP, i would say, read the first post please.

hes a new postie however he has some OC experience, he gave out all numbers we needed, the settings on his board, he was quite through in listing that.

Well, you guys arent answering his quetion, nor are you guys helping him:

He wants 4.0ghz prime stable. :check:

He thinks he's pushing too much voltage: 1.5 :yes he is

He is asking if his temps are fine: Well its on a bit of the high side, but i dont see too much wrong with it.

He is asking for any tips to see if he can hold it stable at a lower voltage. :yes there is sometimes keeping the board cool does help.

He is asking if he shoud reduce his overclock. :for now i would because i honestly think its too much voltage.


Now did YOU happen to say anything of that sort besides the reduction in voltage, and then poping out a oc number/voltage which he clearly says he cant do?

Did you also forget most chips carry a YMMV tag on them? meaning your milage will vary?

Thankfully we have people pushing the limits in the name of research.

OP DO NOT PUSH THAT CHIP AT WHAT YOXXY AND I ARE PUSHING THE CHIP AT.

Yoxxy is running a sub ambient cooling setup which has a evap head temp point of probably -75-80C on a single stage phase unit. Most likely tuned for an old quad he had, so around 200-300W.

I am running a high scale h2o system with a cpu loop only on a MCR320 /w 3 sanace 1011 fans. I have dual DDC-3.2 on XSPC tops, all together yoxxy's setup should cost anywhere from 500-700 while my water setup will run somewhere between 400-500 dollars.

This is the kind of setup thats required for these voltages. You wanna try it, we assume no responsibility, and remember you've been throughly warned.


And i think mine wont last much longer. I got my first invalid, it could of been from a bad task, or the chip is dying. Need to run prime on it to see, and down the overclock. I think i want to keep this chip. Its pretty fun to play around with..

Also my favorate programs:

Coretemp 0.96 or latest
Prime95 25.4+ or higher.
RMClock - A MUST! for lappy's
nTune = When i stress gpu for temps.
RTHDRIBL - stressing GPU.

i dont like everest. But then again, im an old school OCer.

Also im assuming your bios overclocking and not software overclocking.

You just answered your own question. No reduction in OC? Did you miss this entire line?

Should i repost his first post?

You still think your giving out relavant advice?

I wouldnt pick on you so much, however, half the things you start are possible can only be achieved by a GREAT chip, or a Legendary overclocker.

 

[JAG87]

boys boys, all this arguing, so much hostility. OP the answer is simple, you have a shitty chip, sell it and get another one. It shouldn't take more than 1.4v in windows under load for a Penryn to run 4 ghz prime stable.

My Yorkfield's maximum dip is 1.344v with Small FFT, hovers around 1.376v with Large FFT, completely stable. Its not much more binned than your E8400, my QX9650 is fundamentally 2x E8400 dice, both CPUs run at 3 ghz.

A good E8400 will need ~1.3v to be stable at 4 ghz, an average one will need ~1.35v, and a bad one will need ~1.4v (all after vdroop obviously). What you got there is unclassifiable, and remember that setting anything higher than 1.45v in the bios is very harmful to your chip.



PS. this is not a fool proof method of predicting overclock potential (warning to all newbies reading, dont make this a religion), but a VID of 1.220v is disgusting. most E8400s have VIDs of 1.05 and 1.1v, which kind of goes to show that you got a voltage hungry CPU.

*sigh*

If you set your 1.5Vcore in bios down to 1.47, or 1.46 can you still boot?

You just answered your own question. No reduction in OC? Did you miss this entire line?

Should i repost his first post?

I can leave everything on normal/default/auto except for my vcore, I have to manually set it to 1.5 to get it to run at 4ghz.

You still think your giving out relavant advice?

I wouldnt pick on you so much, however, half the things you start are possible can only be achieved by a GREAT chip, or a Legendary overclocker.

Once again you make no sense, except where you say that "half the things I state are only possible on a great chip or great overclocker"

Read zenoth's post that is explaining wolfdale overclocking issues related to ram/fsb or read where jag87 says, "It shouldn't take more than 1.4v in windows under load for a Penryn to run 4 ghz prime stable."

Think about it, be quiet, and help this guy get the 4ghz clock he wants.

Don't tell him it cannot be done and don't tell me to "stop giving bad advice".

I still think english is your second language.

eeeeeasy there superman, you guys have to cool it with the insults... you are fighting over someone else's horrible clocking CPU, do you realize how retarded you sound? get a room already!

OP, there is nothing to be done here. You have an excellent motherboard, a dual core (mosfet overloading is out of the question). The only problem I can see is tuning the FSB and MCH voltages, which I hope you know how to do.

Besides that, you either have a chip that is a bad clocker, or has a very early FSB wall. Sell the chip for 20 bucks less than retail and buy a new one, and keep trying your luck.
