I actually went in and overclocked based on wusy's guide. My memory is set to use the SPD timings which cpu-z is reporting as 5-6-6-18. I'm running 1:1 with a 333FSB.
Ready for the punchline? I've been running Orthos for ~11 hours now and not run into any errors. Core Temp reports the temp never exceeded 48C, and my Vcore is fluxing between 1.336 and 1.352 based on cpu-z.
When the test failed, I had the mem manually set to DDR2-800 with 4-4-4-12 timings. Is it possible for memory to pass a memtest but still fail the blended test because if the timings?
It could be the way in which the memory is accessed that is different. From my understanding, MemTests work to test only the memory.
The ultimate testing software should do one of two things: Attempt to limit the scope of the test down to a single aspect, or too test the system as a whole.
A test that works well at limiting the potential for outside causes to result in bad results allows us to eliminate and/or define key strengths, weaknesses, and defects.
Prime95 tests everything. It tests how the memory works, hence if the memory is defective it will fail. It tests how the memory is accessed, if how the access of the memory fails then the memory isnt bad your North Bridge is. It tests the communication from the processor to the North Bridge. It tests the Cache of the processor. It tests how the memory is handled logically on the processor. And it tests the ability for the processor to use the memory for calculations. And it does so in a complex way that uses a large portion of the processors capabilities. That results in heat, and a higher degree of failure due to stress then almost anything else I have tried.
However, I was running PRIME 95 all night at 318mhz FSB... But my computer would randomly shut down during gaming. I dropped it to 300, and I havent had a problem.
