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

Ive been running that program for the past few days, seems to read exactly 10C lower than coretemp and everest......



Even with this new prog my Wolfdale still idles 7C higher than my Q6600 did under the same watercooling system (Q6600 also ran on higher vcore) :mad:

Also my E8400 is getting more and more unstable, needing a tiny increase in vcore to keep stable at a frequency which was fine a few days ago. it seems to be degrading in front of my eyes.

I’ve had no core 2 that has exhibited this characteristic, and to be frank its scaring me a little.

Feels like the chip is slowly dying :cry:

Will be going back to my trusty Quad asap.

Anyone found there system to be randomly unstable when playing games??

Crysis for example sometimes refuses to even execute! Promptly after noticing this I ran prime and then memtest and no errors were detected. Ran Crysis again thinking it was just a fluke, got into the game only to crash when playing it. After that I dropped the clock and to my surprise crysis will run with no issues.

I’ve ran this game on doggy crucial ram and a far from 100% stable system and it’s been a ok, now with this chip its gone real flaky. Even though my overclock its super stable, well as far as prime and memtest are concerned anyway.

Could it be an FSB issue that only affects games, Imrunning just over 500FSB atm.

Oh, also started using these dandy half multipliers, I’m sure that can’t effect things.
 
Hi there,

I have a 8500, I find that my multiplier seems bugged in CPU-Z. It keeps jumping from 9.5 to 6.

Here is a screen of it:

Any suggestions on how to fix it?

I am currently using a 680i mobo.(BFG)

You've probably got Speedstep turned on.

I checked and it's disabled. Do you think I have this problem due to an OS issue?(im using vista 64)?

Anyway, I also saw something else disabled, MaxVal CPUID - do you know what that is? It says to have it disabled for Windows XP...the comments on the right hand side in the bios says it "changes the value to 3", I assume it's okay to enable it as I am using Vista?:confused:

Leave as is, latencies look fine.

Thanks :) I will keep it as it is! :)

~~anyway it's midnight - I will be back on tomorrow for another shot at solving this E8500 rubix cube.~~

Hi guys,

I'm currently running an e8400 stable on the following settings - FSB 420 x 9 , fsb:dram of 2:1, which gives me 841Mhz on the RAM speed. I'm also running the vcore at 1.3375v, with everything else set to Auto.

This gives me 3.78Ghz on idle at 44c and load hitting 61c (since I'm using vista x64 this is taken with a pinch of salt but I am using coretemp 0.96). Cpu-z also reads that I'm actually just using 1.296 on the vcore?!

My question is, how much further can I push the vcore (and perhaps begin to increase the other voltages)? What's the consensus and the corresponding temps on air (if we can assume the temp readings are vaguely correct).

Although I'm content with 3.7, it would be nice to get to 4Ghz, I just don't want to blindly start ramping up the vcore etc if I need to offset with another voltage/setting etc.

Cheers, Paul.

Temps

Here is an interesting article (though bits are plain hard work):

http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3251

The analysis of the problems with temps shows that it may not be fixable!

I quote:

"More than a few programs have been released over the last few years, each claiming to accurately report these DTS values in real-time. The truth is that none can be fully trusted as the Tjunction values utilized in these transformations may not always be correct. Moreover, Intel representatives have informed us that these as-of-yet unpublished Tjunction values may actually vary from model to model - sometimes even between different steppings - and that the temperature response curves may not be entirely accurate across the whole reporting range. Since all of today's monitoring programs have come to incorrectly assume that Tjunction values are a function of the processor family/stepping only, we have no choice but to call everything we thought we had come to know into question."

With 1.3 vcore in bois and 1.296 in windows you should be able to hit 4 ghz easy and if you want to run your cpu at 3.7ghz then you really don't need that much vcore,i am running my e8400 at 3.8 with 1.240 vcore.
 
I've just come back to the intel scene after having an AMD for the last 3.5yrs and have purchased an E8400, Asus Maximus Formula and 4GB of G.Skill 8500 DDR2.

I notice that my CPU speed is jumping around in CPU-Z, which I'm guessing is the Speedstep doing it's thing.

Is it possible to overclock and run Speedstep at the same time, so I have overclocked performance when I need it and a cool/low power system when I don't?

Yup completely fine, most switch it off during testing, but then switch it on again afterwards. Although from my experience it works fine just leaving it on at all times.
