XP1800 - limited to 12.5x??

teedius · 29th March 2002, 3:11 PM

I've unlocked my XP1800, I'm sure it's unlocked OK cause I can set it to 12x and 12.5x too, and it's picked up in WCPUID and it's got new clock speed in post screen......

......but if I set it to 13x or higher, it looses 80 from the FSB setting?? WTF?? when at 133 x 13 then it drops to 667MHz, 133x 13.5 goes to about 690 etc........is there something else I'm missing or is it a limit of a 12.5x?

(On a A7V333 board)

Cheers
Gav

tried a new bios?

teedius · 29th March 2002, 10:35 PM

yeah, running 1.05 (latest for A7V333).

Someone else said it depends on what was the chip is set as........it's alright anyway ...i found that dropping the multiplier to 11, i can get the fsb up to 152

L 10 bridge on the chip organic pin grid array, control's the ability of the chip to go past 12.5x's in multiplyer's.......

You got the same prob I got. 13x133=1729.
My MSI K7T Turbo lets me select 13x but it really is doing 12.5x133=1662.
Had to up the FSB to get any more outa it. I havent heard from anyone who can get a 13x mult with a 133 based bus.
Mred!
