I have a question for the overclocking experts regarding the use of Memtest86+ and Prime95 to determine system stability.
This is the test scenario thus far:
1) GOOD, Passes all 11 tests in Memtest (PROBE mode) for 13hrs
--2.8C overclocked to 3.3Ghz
(set to 1.625V, but actually reading 1.58V in BIOS PC HEALTH)
--Ram set at 235Mhz with FSB 1:1
2) GOOD, No errors in Prime running for 14hrs
--2.8C overclocked to 3.3Ghz
(set to 1.625V, but actually reading 1.58V in BIOS PC HEALTH)
--Ram set at 188Mhz, FSB 5:4
3) BAD, Error in Prime after only 1 hour
--2.8C overclocked to 3.3Ghz
(set to 1.625V, but actually reading 1.58V in BIOS PC HEALTH)
--Ram set at 235Mhz with FSB 1:1
This is my question to you guys:
If Test 1 implies that memory functions well without errors and Test 2 indicates that processor operates well without errors,
then why does Test 3 fail?
I'd appreciate any help from all you guys.
In fact, if your advice gets me 3.3Ghz 1:1 stable, then I'll buy you
one of those 22oz New-Castle beers in Mammoth--it's my reason for living.
Thanks
