5th Core Fails Everytime!

post #1 of 13
Thread Starter 
5th Core fails every time when running Prime95.
1090T @ 4.0 GHz

1.465V (BIOS)
NB/CPU 1.3V
RAM 1.65V
NB 2.8 HT 2

Why does the 5th core fail? need more voltage?

temps are uber low... about 43C when the 5th core fails....

(also FlashPlayer plugin crashes?)

Yeah, try a little more voltage. That is usually the culprit (in my experience).

edit: Didn't see the thing about FlashPlayer. Not sure on that part.

My 6th core would fail if voltage wasn't up'd. Raise voltage.

Most people on here say that 1.55v is the max safe voltage. As long as you can keep it below 55-56c that would probably be fine. Above that temperature things start to get unpredictable.

Flash player crashing, im guessing while watching a video? If so is your graphics card overclocked?

If it is then thats whats causing flash to crash, simply right click on a youtube video. click settings, then un-tick the hardware acceleration. Worked when i did that when overclocking my mates 5850.

Why does the 5th core fail? need more voltage?

temps are uber low... about 43C when the 5th core fails....

(also FlashPlayer plugin crashes?)
Is 43*C your core or socket temp?

Have you tried with less core and CPU-NB voltage?

My core voltage is at 1.4625 with LLC on, CPU-NB voltage is 1.2875 LLC off. Clocks are 4117mhz and 2973mhz.

Try using some FSB to reach your desired clocks. My rig doesn't like being clocked just with the multipliers.

Be sure you have the latest flash plugin.

thanks.

Im guess flash crashes due to CPU being unstable... nothing else (has ONLY ever done it with an unstable OC, like the 5th core craping out)

43 is socket temp

Flash could be crashing due to instability but it's more likely to get a BSOD instead of just a Flash stopped working error.

For what it's worth, when I was clocking my CPU-NB I had instability at 1.3V and above when I ran IBT. I would try lowering your CPU-NB voltage to 1.28 or so and see if that does anything for you before doing anything else as long as HT is at or close to 2ghz. Your other voltages look a little high compared to mine but every build is different. Just play with it and see what happens.

fixed.... had to raise CPU-NB to 1.31....... magically fixed everything.

now i will try lowering vcore and ram voltage.... see if she stays stable.
