Hi. since months ago I cannot be able to achieve a 100% stable OC. First was the P5Q-E that keeps freezing without any trace of error, and since the onboard sound came dead I replace the mobo for a EP35-DS3 from gigabyte. Now the freezes gone, but now the system keeps giving me BSODs randomly, all related to RAM like irlq_not_less_or_equal, pfn_corrupt_list, driver_irlq_not_less_or_equal, page_fault_in_non_paged_area, VERY weird that this messages appear when the system ARE OCked, and the RAM is UNDER clocked, from 1066 to 950MHz, at stock the RAM works just fine, just the system keeps failing me when the system is under OC. You could say that the OC settings are setted wrong, but seriously I tried A LOT of config (specially the RAM, rated timings, loosen timings) with ANY luck, always the system BSOD with the same errors as above. I'm lost with this issue, the RAM is indeed bad, or could be a incompatibility issue, or It's something more???? Thanx.
