i dont use it so cant really say.

but i know it makes temps go to high and that alone will cause instability.

lol running 16 instances of memtest causes the Nvidia driver to stop responding and recover every so often. Doesn't seem to matter what timings are used. Memtest never reports an error

I use LinX mainly because that's just my method for a stability test and it has been for several Intel generations. Also too low GFlops have been a good indicator if some voltage just isn't correct when overclocking (GFlops must INCREASE instead of decrease thumb.gif). It's a ridiculously stressfull test, I even got my system to fully shut down when I tried 1.39 V. But my CPU is not a good one either, so I'm stuck in lower clocks anyway. After fine-tuning LinX, I move onto Prime95 and try to run it 8-14 hours to confirm stability. It takes a lot of time but so far this has been a bulletproof method for my overclocks. While gaming my CPU temps are 25-30 Celcius lower.

If you want to use LinX, it's best to use the latest version with latest Linpack binaries. Why not going all the way if you want to use it.

VCCSA maybe?

Worth a shot I guess. systems been fine otherwise, testing 8 instances with 75% allocation is fine. 16 instances just throws it over. CPU is definitely stable.

Just goes to show I think people when using memtest specifically should run full 16 instances though on the 5960. Seen a lot of people running 12 or 8

Hi,
I noticed that highering cache voltage helps a lot in stability, also with cache at default frequency.
CPU 4.2GHz, Uncore 3GHz (I cannot increase it)
I increased the cache voltage using offset +0.2v and I set the vcore to 1.250v with a maximum of 1.262v due to LLC8.

I noticed that my CPU loves LLC8 for stability.
CPU at 4.2GHz with 127.3BLCK and 33 multiplier.
In this way the system is rock solid. I can push it hard with every benchmark linx and prime 28 is a no problem, temperature with Linx is up to 85c, 81c with Prime 95.

The only problem occurs with warm reboot.
When I do a warm reboot I get a bd error or a boot loop.

What is the cause of this behaviour?
I noticed that system agent push the voltage to 1.250v when in auto, I have the ram at 3055MHz.

Is there some suggestion to solve the warm reboot bd error or boot loop.

I never experienced this problem with 1.3V on vcore, but is there a way to not increase vcore and don't have a warm reboot error?
It is very stable with 1.250V on vcore I don't want to raise vcore anymore.
Thanks.

It would seem raising from 0.98v to 1.016v has done the trick. Again I'd definitely recommend anyone who's flaunting fancy timings on here to complete 400% at 16 instances, you might be surprised.
