Only way to fix it is to up the VCCIO or perhaps DRAM Voltage.

If you allready set the DRAM Voltage to 1.625v you know it isnt that, so it can only be the VCCIO.

Some Sandy CPU"s just have incredibly weak Memory Controllers, nothing to do about it.

I know $ilent wasn't recommending going above 1.15V on VCCIO, so perhaps I'll try to slowly work it up to see if that helps.

How long does the test run on 1344 before workers start failing? I take it your aware the 1344 tests are not all the same?

They fail immediately. I was just running that test because it's the first test in the guide. If I'm not able to run that test stock then there's not much point in going any further.

The only time ive heard of people failing p95 immediately with workers failing was because of incorrect p95 version, which version do you have? Do you have Virtualization enabled? If not try turning that on.

What is your memory exactly
I mean brand model timings voltage rated by the manufacturer.

Let it never be said that I don't admit my mistakes. Even the stupid ones. I was using 32 bit Prime... 10 years in IT and you still do stupid stuff like that... Could have sworn I downloaded the 64 bit version. It's working now.

I knew it was down to p95 version haha!

Glad you got it sorted thumb.gif

Thanks much for helping. Even though I should have checked that long ago.

Thanks for the reply $ilent. Yeah is there anything else i could try before concluding that my chip cant get past 4.8ghz indefinitely? Is there any thing i could do to the BLCK changing it from 100 to something else? Is there anything i can "try" to hit 5.0ghz (this is just a number based on personal preference - i am not chasing performance just a number rolleyes.gif ) always wanted to do 5.0 24/7 .

And what would you say is the absolute maximum voltage on water? I hear numbers like "1.42 is the max you should go" or 1.45 is the max you should go, or i hear some people saying 1.5v is the definite max you want to go....

what can you say?
