blend test is running now for about 17 hours @4ghz (286x14) without a error, the NB is at 2288mhz at the moment with 1.225 CPU-NB voltage:O
next thing i will test is to increase the memory speed again because its running @ 1144mhz 6-7-6 at the moment. but i had lots of troubles in the past with mem freq over 1400mhz so im not so sure it will be stable when i increase the ram multi.

Good deal, here are a few other thoughts if you have more problems,

You might to consider raising the NB Freq before doing the ram. Try to get it as high as possible 2800-3000MHz and use the CPU/NB voltage increase to off set instability. Be sure to keep HT Link as close to 2000MHz as possible (+/- 100MHz)

Good luck!

If your not aware I find usually when a "worker fails" in prime95 it's a sign of lack of CPU/NB voltage or Dram voltage, (try CPU/NB voltage first)

Maybe this link will help if you have failures late into prime95 testing http://www.overclock.net/general-pro...-settings.html

thanks for the input again, i already switched to stabilizing 2860mhz nb because the stupid bios randomly changes the multi on reboot to 10 which makes it almost impossible to do something below NB multi x10.

im already at 1.350 CPU-NB volt now, everything below froze the system at the 8k FFT. if this is not stable im pretty sure 1.375 will be:O

I just went through something very similar last as I was increasing my OC with the system just freezing, and it turned out a lack of Dram voltage for me.

is this regarding the NB multi issue or the instability with the ram?

The way system would just freeze without showing any errors as you mentioned

well im pretty sure thats caused by to low CPU-NB voltage, as i increased it it took longer till it happened and at 1.325 it stopped together with the p95 errors

hey when i increase the ram freq. can it be that i might need to give some more CPU-NB voltage or should it be stable at what i got it with lower ram freq?

I've found on my setup that it very well could need either more CPU/NB or Dram voltage. That's what I was sharing earlier. It could go either way and just a little trial and error will tell you which. Try one, and if it doesn't improve return that choice than try the other. You at one point may find it to be a combination of the two. That's exactly what I just went through.

ah ok that is good to know so far the 1.325v on the CPU-NB seem to be stable... i will do some more stability testing over night and tomorrow i will experiment a bit with the ram.
