***The Official Wolfdale 8200/8400/8500 Overclocking Thread ***

ayy cooling seems to be alright IMO (compaird to my laptop which when under stress at 1.99ghz would rocket up to almost 70 ) i checked the flatness of the TRUE block with a ruler and was pretty much perfect as far as my eyes could see so im pretty happy with that and dont really wana have to take everything out again and put it back in,..... was fiddly enough before ay there is something definitly a miss somewhere tho hope it gets sorted soon!

also has just been 1 hour stable on small FFT's test lets hope it does the same for the others with this new bios... and some proper temp readings!!!

It's not the cooler that's the problem. It's the cpu itself. Mine is concave (has a dip in the middle) and i was getting bad contact at first. My blocks are all lapped so the centre of the block was'nt quite touching the cpu as i used a thin layer of AS5. Sort of fixed now though. I will let you know if it's still priming later.

ahh cool cool well when i was delicatly holding the cpu and trying to to breath as i put it in place i looked pretty flat to me.. u use orthos or prime95?

ok regardless of the temp settings i went ahead and tried to do some stressing at 3.6 GHz last night to see if it was stable.. heres what i got..


speedfan only went up to 35oC but core temp did raise to 42 ish, i think i put the voltage to auto on the mobo and thats what it came up with.
but the other thing is the mobo temp didnt change atall?! 25 constant? that cant be right, cos i put my hand on the northbridge HS and it was warmer than it was before... hummm but still why the failing

also tried again now just on stock everything and it failed after 12 mins?! wwhats going on

Looks as though there is something wrong here, as I would expect the cpu to do 3.6 on stock volts - mine does and is 12hrs orthos stable.
As been suggested, it maybe the mobo needing a BIOS update, but the thing you wouldn't want to hear, it could be a poor chip - I hope it isn't.

ok just been mucking about for a bit while virginmedia broadband has been rubbish.... again ... back to the point installed bios 601. seems alright, managed to get 3.79GHz to run blend with the DDR at 800MHz, but slight worried about the vdrop still seems to be about 0.06-0.085 not good is it and please dont say that cos i cant just send it back and get a new one
the small and gromacs tests seem to be fine, its just the large and blend that make it fail rapidly.... and atm got it running at 1.4v after settinh like 1.468(or close) in the bios... could this unstability be causing it to fail...?
just had it running at 4.1GHz with 1.432 volts and went unstable after 4 mins

also just booted it at 505FSB with 8x multi, fails yet again only the large and blend tests

 

[Sasso]

really not liking this vdrop... can anyone show me how to do the mod on my p5e? pleasee

Don't forget that because of the appalling vdroop on this board you will be running at significantly lower than 1.4v under load. It won't be the ram holding you back. This is good stuff. I forgot to change mine earlier and then realised it was running at 1188mhz. It seems strange that both of us have very similar rigs and are having similar problems with two different cpu's. I still reckon it's a motherboard problem.

I use Prime95 small fft's to check for stability. 3 1/2 hours stable now at 3.8Ghz (9x400 with the memory at 1066) by the way. Ok it's not great but at least it gives me a starting point. All settings apart from fsb, vcore (1.4v) and vdimm (2.2v) are at Auto. I am not going to fiddle with it anymore today. Going to leave it running prime all night and try to step it up further tomorrow.

Link to the vdroop pencil mod is in one of my earlier posts this afternoon. Hang on, i will dig it out for you.

 

[Sasso]

hehe cool ill try the same and see what happens and if we get similar results ... what ya got ya ram at now 1066 or going for 1:1 ?

 

[pastymuncher]

Here you go, vdroop mod. Post #870. You need a 2B pencil, a torch and a magnifying glass helps. About 5-6 strokes should do it.

Ram is at 1066, have'nt a clue what divider as i always leave the fsb/ram ratio at auto and just select the closest to the stock speed from the ram speed drop down list. You can tighten the timings up quite a bit too. I have had mine at 5-4-4-9 most of the time. Good idea too sort the best stable clock out first though which is why i have set mine back at 5-5-5-15 for the time being.

 

[Sasso]

cool cool, ill go give that ago now see ya in 10 mins, one thing tho, isnt it better to have it like blend stable or dont it matter so much? ahh i dunno this is all so new and confusing

If the ram is running under spec and set at the correct voltage it should'nt fail because of that. Blend is handy for checking overall system stability as it checks a bit of everything. Small fft's put's most of the strain on the cpu which is ideal to test for max clocks.

 

[Sasso]

cool so once thats like 8 hours stable its time to work on bringing in the over all stability? and what ya mean by strokes? just rub the nib from one contact to the other 5-6 times?

If it's stable for 8 hours or and it's as high a clock as you wnat to get then you can then try tweaking voltages etc lower and then re-test. I am not going to stay at 3.8ghz though. I'm greedy and want more. I have to say though, whatever the problem is it's bloody hard going.

Yep, strokes as in from one end to the other. That thing you are actually doing it on is tiny though which is why i said a torch and magnifying glass could be of use. It took me two attempts to get it to work as well.

lol ay me too i would be happy with 4 or 4.2 (espically as im on cooling and this is my first overclock experience) hehe looks like my microscope will come in handy, can it be HB or does it need the extra ruboffness (i know its not a word) of the 2B?

Supposed to be a 2B but someone over at XS used a HB and reckoned it did the job.

 

[MattandJet]

hello all,

ive just got my build together (see sig) and I wondered if anyone has been using the EasyTune5 pro on the gigabyte X38 DS4

btw what sorta clocks can I get for an OcUK 8800GTX?

ATM s at 575,900 (core:memory)

 

[Sasso]

went to the shop cos i couldnt find a 2B... could only get a B and it has made a difference, before the mod 1.4 was turning into 1.36 and a bit lower on stresses, then after a little rubbing with the B 1.4 only dropped to 1.376 and stays constant when idle and under full stress the logic does make sense of it but i didnt believe it would work

 

[Sasso]

ahhh dammit... been going for liek 2 hours on that test and then BSOD suggestions?

 

[Pulse]

just read the last 3 pages of this thread, no-one seems to have gone for the 8200? if you have can you post a few screenies clocks/temps/orthos stability

dont make me be the first to post some but am very tempted. wouldnt mind if the 8200 could hit 4GHz at not much more than stock volts.

 

[Sasso]

humm ok got bored of doing tests after that BSOD, but now ive put it back to stock and UT3 keeps crashing on me ?!

right im uninstalled ut3, got rid of some other stuff, just re sat the HSF (noticed the the fastenning screws on the TRUE had come slightly slack ) booted it back up, everything back to stock.... and now if fails the small FFT test ... something aint right and it also fails the 1M superpi test?! wtf?!?!?!?!

 

[Midget^]

Damn, can only get my e8400 up to 3177mhz, was expecting a bit better .

Had the following settings, tell me if anything looks dodgey:
CPU: 353fsb @ Auto voltage (also tried 1.225v, also failed)
Mem: Set to 1:1 so RAM is only 706mhz (so below the normal 800mhz, can this still cause problems?) @ 2v

Running it on an Asus P5K and OCZ 2gb Platinum. Using stock HSF, intend to replace it but I was still expecting a little more from stock with this chip .
