How well does the e5200 overclock?

[Shmee]

It may be that this little chip has somewhat disappointed us. Mb send it back and get a e6320 if they are the same price rofl? Mine oced VERY nicely with stock cooling, I just dont know what price theyre at now.

 

[faxon]

just out of curiosity, what are people getting for VID on their e5200s? 1.25 here. seemes kind of high for a dual core wholfsdale with 2MB L2, considering shmee's q6600 is 1.25, but then im no expert on VIDs

 

[Foxery]

RealTemp shows the default as 1.18v.

Still happily Folding at 1.30v, 3437 MHz.

 

[SonicTron]

my core's vid is 1.22v

 

[VirtualLarry]

this has probably already been posted, but did you notice - he seems to get 4.0Ghz at 1.384v. Not even 1.4v. Surprising.

BUT, just a question, not sure if this would work, or even help, but does anyone know if the p33 bios works on a 680i LT? keep I know the p31 did, and mb the p32...

right now it is running the p08 bios, the latest one for the LT board.

I know some bios flashing can unlock better features, such as better V control. I would hope an nvidia mobo expert could help us here.

also, a vdrop guide might be nice

When I have time, I'll do this. I have a P35-DS3R with load line droop mod and an e8400 @ 4.0 GHz+ on air (it'll run 4.2 GHz prime stable) on a TRUE, but I need to wait until work is a little less busy. Once I have some free time, I'll do some tests to see where I can take this.

On a DS3L I gotta give around 1.34v-1.35v under load for 3.6ghz. Anything higher than that requires much more volts for each 100mhz increment. I guess I didn't get much of a chip, but I would assume most e5200's probably will clock around that. Then again, the DS3L has horrible vdroop of around 0.07v under load. Another thing is, the FSB on my chip hits a wall at just under 370 somewhere.

that is a cpu preview from july, with a cherry picked intel engineering sample

 

[Freejack2]

Got one of these and put it in today. E5200 SLAY7 (M0) and with an Asus P5Q, Tuniq Tower and OCZ DDR2 1066 ram. I'm testing 3.6ghz (12.5 x 288) at 1.3v. It crashed loading windows at default voltage so I bumped the voltage up to 1.3. Been running Prime95 on both cores for over a half hour now at 49c temps and no problems.
This is only the beginning of testing, I'm going to see how close I can get to 4ghz. Anything to be careful of or watch out for besides not going over 1.4v and 70c?

As others have said, there appear to be low FSB walls. Other than that just keep testing to see where you can go.

I got one built up this week

FSB 333 was a no go at x6 multiplier.
3.5 @ 1.3v (BIOS) / 1.288v (CPU-Z / CPUID HW) is what I got, haven't really pushed beyond that. Not going for major OC, just planning on 3.33 set and forget + speedstep for a machine that is generally on all the time. Testing at 3.5 to give some margin, so I know 3.33 is going to be stable even in the 100F heat we get in summer.

Stock voltage was stable at 3.0 but bombed at 3150, so max stock voltage for my chip is somewhere in-between.

Haven't dropped volts to find what the lowest voltage 3.5 is stable yet, that's next on my list. Once I get there, I reinstall Vista and this comes off the test bench and becomes my main machine.

It may not be a great chip for people who already have 2xxx series chips, but for me, coming from a S939 Dual core, this is a great upgrade. The low FSB means P43 boards are ideal, so you can save money on the board too. With decent DDR2 going for like $50 for 4GB, you get a whole 'just shy of cutting edge' core for just over $200. Looks like all of the board, CPU and mem will be consuming quite a bit less power than my S939 setup to boot, which is an extra bonus.

I still haven't seen anyone try a BSEL mod on these chips. BITD (OMG, wasn't even that long ago) I couldn't hit very high FSB with my E4300 chip until I did a BSEL mod (well, except on my 650i board).

Anyways, worth a try. If anyone lives near me (zip code 53144) I'd do the mod for you at no charge and while you wait (evenings/weekends only). Only catch is that you'd have to bring your rig to me for me to do the mod, and also so that I can verify for myself with before/after results. I can even post screenshots for you.

 

[VirtualLarry]

I don't see how a BSEL mod will help overcome FSB walls.

It can if the FSB wall is there because of the motherboard and not the chip. Until someone tries it, who's to say?

I've personally seen it work, and so has Gary Key.

µATX Part 2: Intel G33 Performance Review

Page 9 ASUS P5K-VM: Overclocking

Our best results with the E2160 and with an external graphics card was a final benchmark stable setting of 9x320 FSB ... Due to strap and chipset timing changes within the BIOS, we could not run our E2160 higher than a 333FSB without locking up the board. We did modify another E2160 to run natively at 1066FSB and did reach a final 9x385 FSB setting.

...

Page 10 Gigabyte GA-G33M-DS2R: Overclocking

Utilizing the E2160 and external GPU we reached a final benchmark stable setting of 9x310 FSB ... The board was actually capable of running at 9x375 FSB with our modified E2160.

All I'm saying is that it is worth a shot, and there is anecdotal evidence that suggests it may help. Don't believe me if you don't want to.

The BSEL mods help when there is a mobo FSB limitation. They do not help with CPU FSB limitations. That's all I'm saying.

Considering that someone said they had a CPU limit of 310 FSB, it sounds to me like the problem is likely to be the CPU itself not being able to hit 333.

3330 MHz @ 1.26v (BIOS, less vdrop) not stable. It's not a high-end motherboard, and I haven't tried higher voltages yet.

The one I built for niece is doing 3.33ghz with stock cooler prime95 stable for 6+ hours...I believe it was at 1.3v set in bios and 1.26-1.27v actual...

I have had it running superpi at 3.6ghz with stock cooler...wont pass prime and i dont want to give it more then 1.35v actual with the stock cooler...

She is never going to need that power so I backed it down to stock....It seems to run nice and cool

So one of them actually got to 4Ghz, eh? I don't know if I would run 1.5v (actual?) 24/7, seems risky to me. Then again, if you're going to replace your CPU in two years anyways, why not.

 

[Lemon law]

Just want to point out that the e5200 is just the baby brother in a near future intel plans for the e5200, e5300, and e5400 family of processors. The e5300 is already born, the e5400 is due to be born in January of next year, and there is a intel planned $20. drop in e5200 prices coming when the e5400 is released.

Heat wise, lots of good things to be said about the new intel 45nm 65 watt processors. Not only is less heat generated, the intel published red line basically rises from 63.4 C to 71.4 C compared to 65nm fabs.

The furnished intel heat sink and fan may be decidedly inferior, but that is easily fixed.

 

[Duvie]

dont forget the fact the E5xxx series has less cache that plays into some of the heat savings......

 

[OCNewbie]

I believe the E5300 is a new stepping too. Got one of these E5200's for my friend and want to try to get him at least to 3 GHz+, hopefully on stock volts.

 

[bigblockchevy]

i have seen a couple hit 4g. but there v-core seemed high. the one thing for sure so far everybody is operating these things in the 300-369fsb range. if the new stepping can pull 400fsb even @6x--i am going to order one!!!

it could be interesting to OC with that high multi.

Why is that? you think not having the system fsb be 1600mhz is going to hurt you that bad? heck the smaller L2 cache pool hurts you more than that...might as well get the E7xxx or E8xxx series then....

Has anyone tried a BSEL mod on it? Worth a shot.

Yes, the BSEL mod does work.

Same as doing the mod on E4xxx processors from 800 to 1066 FSB.

 

[francisA]

I did the BSEL mod on my E5200 (x12.5) and ran 24hrs on Orthos. But had to give it 1.3375v. My mobo is the 4CoreDual so had to do the vid mod on the CPU itself.
Now running 280fsb with 12.5 multi (3.5GHz) still at 1.3375v and it was Orthos stable for 12hrs. Haven't tried running it longer though.

Planning on upping the vcore to max 1.3625v which I believe is the max rating for 45nm procs. Maybe I'll reach 3.6GHz or a little over but I don't think it'll go much further than that. If I do 285fsb on my current vcore, it will only run Orthos for 2hrs and fail rounding. Maybe partly due to the fact that my CPU started with 1.225v stock so there's not much oc headroom (just a guess).

Soon, I might get the EP45-UD3P and hopefully get more from it.

 

[JmsAndrsn]

The one I modded had a default of 1.20v I believe. The chip needed about 1.3v to run at 3.33GHz so I went and modded default voltage to 1.35v for good measure.
