E4300 Overclocks?

[Soulkeeper]

i had to back down to 2.9GHz to be stable

the problem for me definately appears to be the motherboard not liking fsb speeds over 1300Mhz
if i could set the clock mult higher the cpu would almost certainly function over 3GHz stable

Two questions:
1. Any consensus on what the best motherboards are?
2. What would be the conservative settings, to leave it untouched for a couple of years? I don't want to push it too much, since its default speed is enough for most of the time the computer is on.
3. After market HSF obligatory?

I just hooked up the e4300, Tuniq, and DS3 combo last night.

My Windows repair was having issues last night so I have not booted this into Windows properly but the temp reading in BIOS for the CPU was 17C! This is without the Tuniq's fan on! I just found out from someone here and GB's Tech Support that I have to disable the Speed Control to have the fan running 24-7 instead of having the fan start up when it reaches a certain temperature. I just hope the sensor isn't wrong. I'll check out Coretemp and TAT tonight.

What are your stock idle temps for the combo or any stock idle temps, other than stock HSF, for that matter?

I ordered a E4300 with the P5B Deluxe Asus board and a Zalman 9700 HSF with a Antec 900 case, I will keep ya up to date with temps and clock speeds I am able to get as soon as I receive it!

e4300
ASUS P5B (Plain Vanilla)
2 x 1Gig Kingston DDR2 667
Thermalright Ultra-90

3.0ghz - 1.3500 vcore - Orthos stable
3.1ghz - 1.3625 vcore - Orthos stable
3.2ghz - 1.4375 vcore - Orthos stable
3.3ghz - 1.5000 vcore - Orthos stable

--------------------------------------
With stock Intel Heat-Sink and Fan

2.8ghz - 1.25 vcore - Orthos stable
3.0ghz - 1.35 vcore - Orthos stable

Didn't go higher becuase I was concerned about heat. 3.0 was hitting low 60s (celcius) with stock Intel HSF

 

[DarkMadMax]

E4300
Gigabyte P965 S3
Cooler Master Hyper TX on AS5
OCZ 6400

OC to 3200 with 1.35 (stock 1.325) . Seems stable (ran orthos ,S&M) at 60 C. TAT shows wierd temps though 20-25 degrees higher than coretemp and pcwizard ( 80-90 C under load) . Rather unhappy with such pathetic OC -expected at least 3400 ,based on Anands review

This came to mind when Anand said they needed almost 1.5 to get 3.4 ..

Looks like these may be down-binned 6300, 6400, etc ...

Nah, completely different cores.

Which Orthos test did you use (blended, or cpu?) and for how long did they run?

I did Orthos CPU for about an hour and then I switched to the Blend test for multi-hour tests, with a couple running over night (10+ hours).

As I moved the Bus Speed up I would have to make several incremental vcore adjustments to pass Orthos. I seemed to find common thresholds with each major step as I moved Bus Speed up 11 points (e.g. 345 to 356) the Orthos CPU test might fail immediately, then I would adjust vcore one notch and Orthos would fail at about 2 minutes; adjust vcore up one more notch and Orthos failed at ~30 minutes; adjust vcore up again and it would smooth out. Then I would switch to Orthos Blend and go watch TV or go run an errand for a few hours. The Blend test uses 100% of both CPUs and about 65% of memory according to the UI. With the 3.0g and 3.1g I let it run overnight with no problems. I ran the 3.2 and 3.3 over-clocks for 3+ hours.

I haven't OC'd in ages, but am considering getting one of these E4300's. I already have an EVGA 680i MB, but I don't have the RAM or CPU yet. I would only like a modest OC to 3Ghz, which seems very possible with these processors. My question is what kind of ram would I need to achieve this?

The E4300's have a 9X multiplier so with an FSB of 333, that would get me 2.997Ghz right? Also, would the memory be running 1:1 with the FSB so any DDR333 ram would be fine?

Hi,

Memtest passed 3 full tests, 10 passes of test 5 alone. SP2004 ran stable for 15 minutes, before I ran 2 instances of Super PI which finished in 30min37secs successfully. Max temp till now was 63C in my Asus PC Probe. Then I ran Prime95 2 instances(each with 512 MB in torture test and CPU affinity set to core 0 and 1 respectively). One instance failed after 3 hours and 55 mins and CPU temp went up to 81 C(average was 72 C). I know this is high, but system is stable and responsive, so I guess the PC Probe is returning wrong temps. Any other apps/source to get correct temps? MB temp is around 45C max, while Vcore is 1.34-1.39V.

 

[skarkar]

Yes, I'm using Transcend JetRAM DDR2-667 at FSB 333 1:1 and its kinda stable except for the one failure with Prime 95. I've been doing all this with stock HSF and stock voltages, a budget setup for sure. My RAM runs fine at DDR2-800, as most 667 RAM can run at DDR2-800 also, but I guess I need to up the NB voltage, where I'm inexperienced.

 

[skarkar]

Just downloaded coretemp and it shows the 2 cores at 65-68C with the TJunction being 85C whatever Tjunc means. So, ASUS PC Probe is reporting > 10-15C temperatures in my case Am getting some arctic silver and some antec coolers. Let me know of some good antec coolers, for the 4300.

 

[cnhoff]

Why not another cooler?

Firingsquad has just posted a C2D cooler roundup.

 

[TripperJoe]

Is this ram from the hotdeals forum gonna be able to make 3.0-3.5ghz without too much of a performance sacrifice? (assuming the cpu can handle it)

Thinking about going with the 4300...

 

[Traveler]

I guess this is C2D I've been waiting for since I bought PD805 last year.
I overclock my PD805 from 2.66 to 3.19.
But overclocking E4300 from 1.8 to 3.42 sounds kind of extreme, the heat, omg, the heat...

Which FSB of RAM can E4300 can run up with?

That's the great thing. To run PC6400 at stock speed you'd need to be at 3.6Ghz which you probably won't be. I just got some decent quality PC5300 and it's currently running below stock speeds even with a 1Ghz OC on my cpu.

 

[quest55720]

Not to thread jack but I will be over clocking my e-4300 in a few days been a long time since I have overclocks. I have othos clock gen and tat. What other utilities would you all recommend? Also what features do I need to turn off on my motherboard to get TaT to work? It gives me a Error enumerating On Demand Clock Modulation Support I have narrowed it down to some bios feature that protects the cpu from burning up. I disabled the smart fan and the CPU over heating shutdown features. I have a biostar P965pt what else do I need to disable to get TaT to work?

I just got my system set up. I have the Gigabyte S3 (not DS3), E4300 (stock cooler), and Corsair PC6400/800mhz memory. I was stable at 3ghz (333mhz), but failed Orthos at 3.3ghz (366mhz). I can probably bump up the vcores to get that stable.

What I can't figure out is why I can't POST at 400mhz fsb. I set my CPU multiplier to 6x, so the CPU should be running at 2.4ghz. I tried bumping the fsb and mch vcores to +0.3v, PCI express +0.1v, DDR +0.4v, and nothing. I even added a 40mm fan to the northbridge.

What am I missing? Anyone else have this problem?

The Northbridge core clock is overclocked to 600 MHz in the configuration you mentioned. That's probably why it won't post. This is a little-known "feature" of the P965 chipset...
Actual NB speed = (stock multiplier) / (set multiplier) * FSB. Or in your case, 9/6 * 400 = 600.
See post by FreeCableGuy in this link.

Well, 3.35 GHz on an e4300 is nothing to sneeze at.

On the other hand, something seems fishy here... If your cpu can do 3.35 GHZ then it should be able to do it at 9 x 372 or at 8 x 418. And since your board is a DS3, it should have no problem with the 418 FSB... the DS3 can go up to 500+ FSB.

There's a chance you could go higher if you solve this mystery... maybe increase the FSB voltage by +0.20V to +0.30V. I've heard of that curing stability problems on the DS3 board above 400 FSB. Then you might be able to lower your cpu voltage back down and you wouldn't run into the heat problems you mentioned.

Yeah, I was baffled by this as well. I tried 400-425fsb but can't seem to get it to post at all, even with the extra FSB, MCH overvoltage, or extra vCore. Even if it does post, it'll probably just be hella unstable and crash in windows like it did with 390fsb. Not quite sure whats up with that.

Just to check... you sure your memory can run at DDR 850 speed, and your mem timings aren't too aggressive?

You need DDR2 667 (also known as PC 5300)... DDR speeds are double the FSB speed at a 1:1 ratio.

Its rated for DDR-800. What I meant was since I got it to boot at 390fsb but not stable in windows, I didn't think pushing it past 400 would show anything.
Memory timings are at 5-5-5-15, they're rated for 5-5-5-12.

 

[skarkar]

I'm running a 4300 on Asus P5B and got it stable at 3 GHZ, 9 multi, DDR2-667 333 FSB at stock voltages and stock HSF. My RAM runs fine at 4-4-4-12 DDR2-800, but if I set FSB to 400 and RAM to DDR2-800 and up the CPU voltage to 1.525 system doesn't POST. Any FSB holes at 400 in the Asus-P5B or do I need to up the NorthBridge voltage and RAM voltage too?

 

[rookiE6400]

Hello everyone,

i jumped on the Fry's deal of $149 for E4300 tray + ECS p4m800pro combo, and then went and got the following:
- Biostar tforce 965pt (using beta bios 119 to get 400Mhz for memory)
- arctic cooling freezer 7 pro
- APEX AL-B500E ATX 500W
- Antec sx-635
- corsair xms2 2gb (675, 4-4-4-12)
- geforce 6100 turbo cache (yes, i know... saving up for X1950Pro)

after 2 days of tweaking, this is where i am at:
9x334, 1.45 vcore (system wont POST with 333x9 for some reason)

orthos blend full load temp: speedfan 57c, core temp shows 5-10c lower?!, TAT wont run "error enumerating on demand clock modulation support")
idle temp: 30c speedfan

i am at 1.4 Vfsb and 1.45 Vmch, and 2.2 vdimm 5-5-5-15, trying to get highest OC on CPU

could someone give me some pointers on how to get the vcore/temp down (and perhaps push OC up some more) or i am SOL on this chip?

thanks in advance
