installed new drivers 8.7, set memory to 791 MHz (5-5-5-5), launched 4 llrnet, launched game, played 10 minutes... still have errors
ERROR: ROUND OFF (0.5) > 0.40

Now this error is much more likely to be a hardware error than a software error. I'll let VJS take the lead on this, but have you tried to large fan pointed at your machine (or pointed away from it) to increase the air flow. Too many people put their machines in those "cute" little computer desks to get them out of the way.

open case ;) temperature around 65 (coretemp)

So far you returned 16 results on the DC server with two results not matching to the first pass. But this does not mean that your results are wrong. A third test will be needed to close the case. There is a very good chance that your results are correct as we are working on a range which is know to have bad first results.

If somebody has the time( My machines are doing other third pass tests at the moment to investigate other possible error pattern ) here are the pairs that need to be retestet:

258317 2587559
79817 2588031

Cheers,

Well your on the right track,

Couple things... first coretemp.exe will not tell you 65C for a q6600 it will provide you 4 different temperatures one for each core. What are those temperatures...

Also 65C is still too hot but your close.


Joe is right that error is certainly hardware related and not software.

I'm trying to be helpful but I can't continue or certianly not help if you won't answer my questions.

Please answer the following...

are you still running a 9X or are you running 8X?

You should be running 8X at this point.

Looking at the picture I have an oh no... what power supply is that? How many watts...

Also you still have not told me what voltage your running at or which memory you are using?

Looking at the pic I would also suggest a larger fan in tha back replace the blue one with a 120mm or biggest you can fit. I purchased about 4 of them at fry's for $4.95 each so they are cheap.

I would also put the side back on after you put a larger fan in back. Open cases really don't work well, you need to get the cold air coming in the front and bottom hot out the back and top. Generally I'm able to get case temps around 26C without work or problems.

Memory Samsung PC2-6400 (5-5-5-5) 1.8V 790 (or 791) MHz
Power supply suxx :) Hopely 400W
Temperature right now 66 on 2 cores and 63-64 on other two.
8x395 1.55V in BIOS. It goes to 1.36-1.368 during work (cpu-z)

I've sent 12 more results... So the problem can be in power supply? When videocard switches to 3d-mode?

They take more power when you kick into the 3d stuff. Most current cards go to a slower speed for 2d and full speed for the 3d. Think of it as speed step for the gpu. Add in the fan rpm bump from the extra heat (minor but it is more power).

So if I'll buy for example Sirtec 500W, the problem would go away?

Ahh now we know what the problem is...

Memory is not great but your doing the best you can with what you have.

Temperature right now 66 on 2 cores and 63-64 on other two.

O.K. your about 3 degrees to hot on the first two cores, simple fix... can probably be done with cooling but your real issue is power supply. As evident by your next post...

8x395 1.55V in BIOS. It goes to 1.36-1.368 during work (cpu-z)

So your looking at about a 0.2V drop under load and when that card kicks in drawing alot of power your CPU voltage drops even further...

Increasing the volatge further is not going to help your powersupply is just not up to the task of running at that Mhz.

I know it doesn't really make sence but a large voltage drop generates alot of heat remember I^2 r and V^2 / r you still need to produce the power at the cpu and if you can't give it the voltage it takes more current which causes excessive heat.

BTW 1.55V is probably going to kill that chip at that heat level... at least with time.

My suggestion get the largest single rail powersupply of at least 700watts with a 8-pin power.

Until then you should probably run at 7X400 and drop that CPU volatge down to about 1.4V. Might stabilize things a little. If you get a decent power supply and some case fans it sounds like you may even be stable at 3.6Ghz. But you would need to get that temperature down to a high 50's maybe 60C on the hottest core.

BTW 7x400 is actually 2800Mhz.

If you look at the errors Lars talked about 2 errors in 16. If those two errors are actually your errors.

Then,

Out of 16 you had 14 good tests.

8x395 is 3160 Mhz multiply by 14 / 16 is 2765 Mhz...


If you ran that CPU at 2765 Mhz and produced no errors you would have been more successfull.

In actual if you ran 100% stable at 2800 Mhz you would be more successfull...

In any case I'm sure we can get it stable at more than 2.8Mhz for certain. And stability at 3.2 Ghz is very easy with the right parts.
