Computer details:
Core2Duo E6750 3.2GHZ(8x400), GigaByte GA-P31-S3L, Corsair 2x1G DDR2 PC6400 C4 @ 1:1RAM (5 5 5 18 @ 800),
Themaltake Armor Jr (Aluminium Modded), Nvidia GeForce 7300 (512MB), 160G SATA W/Digital HDD,
CPU Scythe Ninja (120mm Fan), FANS: 1x120mm Front, 1x120mm Rear, 2x120mm Top Exhaust
I'm been overclocking this Mainboard (GA-P31-S3L) now for about 6 months, and altho I can get it Orthos stable for countless hours,
I'm getting irregular cold boot issues. Meaning the board reverts to stock settings, and I have to go back in and restore my overclock.
I've tried every combination of voltage increase, FSB speed, and always tried to keep a 1:1 setting. Even with Ram set to Auto,
I get this problem. At the moment, I can only seem to hold a 3.2Ghz o/clock (400x8) with Vcore 1.328v in Cpu-Z.
I've added +.1v to PCI-E, +.2v to FSB, and +.2v to MCH.
The ram timings are manually set 5 5 5 18 @ 2.1v, with 1:1, so running at 800Mhz.
Any FSB above 400 tends to bring out the cold boot issue real quick. I believe the Ram is verified to run at 4 4 4 12 @ 400Mhz,
but as soon as I tighten the timings, altho it runs stable, it won't cold boot regularly.
I've researched my motherboard, and am confident the P31 is a reasonably good overclocking board,
and as I'm not overclocking the Ram, I'm curious as to why I have the cold boot issue.
I would be more than happy to get a stable 3.6Ghz o/clock.
If anyone has any ideas on memory timings etc, I'd greatly appreciate it.
Sorry for the long read.
