Rounding error during Prime95 -- up RAM voltage?
Last response: in Overclocking
I have an i5 2500k that I started to OC. I also have 2x Gskill Ripjaws DDR3 1600 4GB RAM.
I have started to overclock and the CPU is stable through intelburntest high 25x and Prime95 using small EFT @ 4.4Ghz + 1.280V. However, when I run a blend test I see rounding errors. From what I've read these are errors associated with the RAM. Do I need to up the voltage? They're 1.5V sticks.. here are my settings (what the package said to do..):
1.5V - 9 -9 - 9 - 24 - 2t

I've seen rounding errors with insufficient CPU voltage as well, so that's a possibility.
Don't increase the RAM voltage quite yet. You shouldn't have to do that unless you have four RAM sticks.
Do this first: Check your VTT/VCCIO voltage -- if it's not 1.15v, increase it to that.
If it still gives errors, increase the CPU voltage to at least 1.3v and try again.

I up'd it to 1.15V (was 1.05V) and still saw a blue screen.
The thing that perplexes me the most is the fact that the CPU tests pass with flying colors but once I start the blend, I see rounding errors or blue screens. I've increased the voltage and it's hanging out around 1.288 - 1.296 during a blend. I ran it for around 30 minutes and it was fine. I'll do a longer test once I'm away from the machine.
