I have a serious problem with my Athlon 1333MHz 266FSB C.P.U and asus motherboard. Firstly, I had a ECS mainboard which I bought with the processor new which ran it fine until it burnt out. I then bought an Asus A7v8x-x mainboard but now the processor will only run at 1000Mhz. When I set the processor to run at 1333Mhz, the board just loops in safe mode. When the processor was tried with another board, it works fine. According to Asus, the board supports the processor fully. Ive already tried flashing the bios. There is no manually jumpers to set on the board only the bios software. I need help please!!!!! This processor is only running t 75% of it's capabilities. Does any1 know how to fix this?

Welcome to the forum.

Sounds like your new board is not running at 133 (266) bus speed.

IIRC the multiplier on your Athlon 1.33 is 10, so logically 10x133.3333 ~ 1333Mhz.

right now you are at 10x100 ~ 1000MHz

Verify the jumpers or bios settings for the proceesor bus speed is set to 133 (266) on the mainboard.

Good Luck

maybe your motherboard burning out affected your cpu...

I have the same motherboard, and I know you can change the multiplier...would it be feasible to leave it at 100mhz fsb and set a multiplier of 13 for 1300mhz??

there is a jumper on the upper left hand corner of the motherboard that will allow further FSB adjustments, but I think the default would still allow 133 or 166 mhz fsb...
