Am running 2 sets of G.Skill F2-6400CL4D-4GBPIB (PI Black) and have recently found the time to overclock and thoroughly test the DRAM.
My problem is that while XP boots and runs fine at these settings, LinX would fail after about 20 minutes. I prefer LinX because Prime95 (x64, custom blend) passed the 2-hour mark with no error. LinX passed 20 rounds both at stock CPU/memory settings and when only the CPU was overclocked so I think it's safe to say that components are good to begin with. I need help in fine-tuning the board.
Before anyone asked, I had to raise the ICH core because I was getting file corruptions at stock voltage, even at stock speeds. I think my USB keyboard's built-in audio has something to do with it (not enough power for the headphones?).
I had to RMA a revision 1.1 board (bad LAN2) and noticed that board was able to run the same modules up to 458MHZ without having to lower MCH reference like I had to with this 1.6 unit. Different revision = different OC? Maybe not. I didn't stress test much then.
Any comment/suggestion will be appreciated. Thanks, guys.
