I just tried to upgrade my system from 6gb to 12gb and can't seem to overclock at all. I've tried all the ASROCK predefined overclock settings to no avail. Command Rate is 2t for all configurations. As you can see from my sig, this system works fine at 4.2ghz with 6gb, but won't even boot at the Asrock EZ OC 3.6ghz settings with 12gb.
Actually, even at 4.2ghz with 6gb, the system would still automatically reduce the cpu multiplier from 21 to 20 resulting in 4ghz at maximum load. Never was able to figure out how to hold the cpu multi to 21, but didn't matter. 4ghz under max load was fine. Nevertheless, none of that matters now, if I want to use 12gb (and I do for virtual machine software work...), since I can't seem to figure out how to overclock with more ram.
Any ideas? I'm sure I'm missing some obscure voltage setting or the like. I can run at default settings at 2.67ghz (20x133) or even 2.8ghz (21x133), but nothing more than that using EZ OC. The RAM is Corsair XMS3 Cas8 and tests fine with Memtest86+ v4.10 at default settings. Any help would be greatly appreciated. Thanx in advance.
