First off, as you can tell from the impressive post count, I'm a bit of a noob to overclocking. (I know vaguely what I'm doing, but I've never overclocked anything this sophisticated before).
Anyway, the issue:
I'm running a 6400 on a Gigabyte ds4 (rev 1) with the F7b bios. I've got 2gb Corsair CM2X1024-6400C4, an Arctic Cooling Freezer 7 pro and a 600w Tagan Easycon.
I recently built a 6300 rig using a ds3 for a friend, and it got it running stable @ 420mhz @1.375v. (With minimal effort). I figured I'd be able to at least hit 400mhz on my ds4, considering it should be a much better overclocker. Unfortunately, it all goes pear-shaped as soon as I push it past 350mhz. Anything higher and I get errors as soon as it boots into Windows (errors seem fairly random - generic bsod/one usb related adn one about win32k.sys).
So far here's what I've done:
(G)MCH overvoltage @ +0.2
FSB Overvoltage @ +0.2
DDR Overvoltage @ +0.3
CPU voltage @ 1.388
Memory Multiplier @ 2
I even tried flashing the bios to F5, but other than giving me problems with my X-Fi, it didn't help at all (so I switched back to f7b).
I've also disabled cuid max, C1E, EIST and virtualization tech. I've left the memory timings alone, as I didn't think they would matter if the memory is underclocked or at stock (assuming that 400x2 is still the 800 it's rated for).
I'm at a complete loss as I should be able to get higher clocks, surely? It's stable at 350, but even 360 will only boot stable about 1 time in 3.
Cheers!
