Update F15,
I bought an Epox 4SDA/1.8a/256 crucial oem. I get no crashes at 2.4g until i run a game or prime95!!!
Prime will not run untill I reduce my cpu speed. First good test of prime(5hrs) completed at 124mHz FSB.
I could go/try faster. When prime failed at 2.4G(133mHz FSB) it only took a couple of minutes.
NOTE: I can run many benchmarks at 2.4G. Sandra, pcmark,3Dmark2001se, Hot cpu tester 2 lite...ect. All other benchmarks completed without halting or crashing. Some can be run overnight(Hot cpu lite), and were!
I'm requesting other using sis 645 chipsets try prime95. Torcher/ normal operations are the tests that fail.
Regards
