Opty OC prob my mobo doesnt like > 300 FSB

post #1 of 7
Thread Starter 
And thats been posted before and kind of expected, so I try and OC my RAM and even if I only switch it from Auto to Manual and make no other changes windows wont load I upped the voltage to 3.0 (my max) and no diff Whats up? HTT is at 3, CPU 307x9 @ 1.48
mem is auto/manual Cas 3, Tras7, Trcd3, Trd 3 max freq @333
Im not entirly bummed w/ my 2.7 OC but Im wondering if the wall is mobo or RAM
any help would be appreciated!

With the Asus A8N Mb there are some issues which limit it's OC capability.

1. CPC 1T will not be stable above 240 so best to leave this at 2T which is the Default

2. The way to manually OC this MB is not always straight forward such as MaxMem for the Mem divider - check out the FAQ on this MB to help you further.

3. The Max Speed for these MBs is around 315 as at 320 the PCIe bus drops the SATA controller.

4. Max Vcore is 1.55v so this will limit most CPU OC

5. Max Vdimm is 3.0v so BH/UTT modules will not do well in this MB at tight lat.

With your CPU the X9 multi is a challenge and so you really need high bus speeds, 270-300+, to get the best from these chips.

I've unfortunatly got all those bases covered running at 2T with loose timings at max vcore etc Ive gone to the FAQ on my board and set the timings as per recommended but... Oh well 2.8 and 1mb L1 cache isnt too shabby for $168.00 I paid for the chip

It would seem that you have already maxed out the Asus MB if running 310x9... so should there be more legs in the CPU then you will need to change to a MB that can run higher speeds, such as a DFI and you will see more performance from the same CPU / memory.

I do believe that you have misread between the two Sigs ... my Opteron is a 146 ... read about it here
