Hi Guys, First post here so be gentle, I did do a search for this but cant seem to find it covered anywhere
Hardware involved :-
Mobo - Gigabyte M720-US3 Rev 1.1
Bios - Award F6 (latest stable none beta version)
Processor - AMD Phenom II 555 Stock Speed 3.2 GHZ
Cooling - Corsair H50 with Dual 120mm fans in a Push - Pull Config
Memmory - OCZ PC26400 (DDRII @ 800mhz)
GFX - XFX Radeon HD5770
Now I was aware before buying the processor that I may be able to unlock the 2 additional cores to make it into a quad core, I have tried this several times and it locks the system up on Prime95 with in a few seconds of launch. So I have decied rather than have a quad core I would go for a 4ghz Dual core.
I have seen Screenshots with this possible, and can see that it involves increasing the FSB as well as the multiplier, Since this is my first real over clock I am a bit cautious about increasing the FSB, as my understanding about this, it increases the speed of everything on the mobo and not just the processor.
at the moment I have a rock solid over clock at 3.8ghz and I know I have room for a lot more as my temps are pretty low at the moment 20c idle, 30ish at full load
So (sorry so long winded) what I am trying to do is reach 4ghz via Multiplier only, However, the Gigabyte M720-US3 that I currently have is only accpting a x19 option,
if I try a x19.5 or a x20 option (which would give me the 4ghz) it defaults back to auto or x11
what I am wondering is this a limitation on the mobo, or have I got a weired Bios flash ? if its a bios issue, would going to an ealier version work ?
Sorry for the long post but I like give a little background
