GX260 CPU clock speed after upgrade
Hello everyone,
I'm having a bit of trouble with my GX260 and a cpu upgrade I recently performed. I've searched the net in general and also the forums. Thus far what I have found is that the BIOS version A06 is best for compatiblity which unfortunately I'm currently running A09. The stock CPU with this system was a 1.8GHZ P4 which I'm trying to replace it with a 2.4GHZ P4 here is the specific information.
PROCESSOR, 80546, 2.8, 1M, PENTIUM 4 PRESCOTT DT, 800, D0
From what I understand this system board preferes the Intel Prescott but for some reason I can't get the bios to run the cpu faster than 1.2GHZ. Prior to installing it I switched the BIOS CPU config to compatible just to be safer and I don't think it's ever got out of that speed even after changing the config to "normal" which is the only other option.
I'm preparing to flash the BIOS with AO6 this evening when I get home but does anyone know of any other tools that might be useful or other steps I can take to get more speed. Is there any way I can actually get in to look at the clock speed settings, I tried the open manage or whatever the bios configuration client is called with no luck. Please advise
Thanks

This chipset supports 400MHz and 533MHz front side bus only (see here).
So your 800 MHz FSB chip isn't supported. If you're 'lucky', you may get it to work at either 1.4GHz (on 400MHz FSB) or 1.86GHz (533FSB). You cannot set the busspeed on the Dell Optiplex P4 systems; it reads them from the processor, so as it cannot properly negotiate a bus speed, it probably reverts to a slowest possible speed.

The hottest CPU for the 260 is the hard to find 3.06 Northwood with 533 MHz FSB.

This shows a link to what you want. I am not familiar at all with this vendor, however.
This was as cheap as I could find for a new one. The boxed items have a better guarantee, but I could not find it.
Be sure and upgrade to the 9Y212 heatsink and P0676 fan/shroud if you upgrade CPU. They were designed for the 3.0GHz and up socket 478s on Dells.

Guess the answer was staring me square in the face but I didn't recognize it, guess that's why I needed an outside view. It was a system pull processor anyway so it's better that it didn't work, I was just trying to make a quick upgrade.
Thanks for getting to my question.
