I just put together a rig for my brother-in-law with an E6300, Geil DDR2-800, and a Biostar TForce 965PT mobo, and I'm trying to find stable settings for a modest overclock (in the range of ~2.4-2.5 GHz). First of all, even at stock settings, this system absolutely destroys my main AMD rig in my sig :( , so I really don't need to push this thing too far.

The problem is that I am completely new to Conroe CPUs and DDR2 memory, so I have no idea where to start. I don't have time to go through a slow, incremental approach to achieve this overclock. I just want to find some stable settings, tweak it a bit, and then leave it alone. Right now I am trying 350x7=2450 MHz with memory 1:1 (that's what the DDR2-800 setting in BIOS means, right?), Vcore at 1.350V and VDimm at 2.0V and "auto" (SPD) timings. Unfortunately, I am failing Prime95 test on the Ultimate Boot CD at these settings. I know what I need to do to figure out what is causing the problem, but I believe I can save some time if I can get "ballpark" estimates of the voltages and timings that I should start with at these settings.

The Geil memory is rated for 4-4-4-12 at 2.0-2.1V. I'm not sure what the SPD timings are, so should I manually set these timings in BIOS? Memtest86 seems to be running without errors at my current settings, but that's not really an indication of stability. On AMD systems one could just employ a memory divider when finding the stability threshold of the CPU. Will the same principle apply here if I change the memory speed to the [DDR2-533 setting] and increase only the FSB?

Thanks in advance for any help you can offer.

EDIT: Oops, I'm an idiot. A memory clock setting of 533 MHz is 1:1. No wonder I had to reset the CMOS when I tried booting at 350x7 with memory on the 800 MHz divider! :eek:
