Hi all,
I just bought a E8200 intel CPU. It runs on a Gigabyte GA-P35-DS3R, with 1x4 GB of Kingston 667mhz value ram. (Pairs). Using the stock cooler that came with the Intel CPU, the chassis is cooled by x2 120mm coolers.
My problem is pretty straight forward. At stock settings(CPU: 8x333fsb 1.15v RAM: x2.0 667mhz 1.8v) , my Prime95 25.5a torture test will fail within seconds of starting. With the following error:
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
I have tried different multiplier settings:
7x333fsb = failed with same result
6x333fsb = failed with same result
The only stable speed I have been able to obtain is 8x250mhz. Here it can run Prime95 all day long. With a CPU temp. in the higher 50c.
A memtest86 at 333fsb will give around 12 errors. I have yet to test it at fsb250mhz.
My question is... which component is failing? Is it the CPU? Doesn't seem like it's the one that is failing the test. Is it the ram? It should be noted that I have taken every single block out and tested it by it self with the same result as when all 4 are installed, when running Prime95. Is it the motherboard that is unable to run at more then 250mhz? Is there some way of testing this?
Another note:
I have a spare E2180, which is supposed to be able to run around the 333fsb mark. But I was never able to get it even close to that when overclocking. I just figured I had gotten unlucky with the CPU. This again could lead to the motherboard being faulty? Is there some way of testing this?
