Advanced CPU knowledge needed...

post #1 of 5
Thread Starter 
So here's the question up front, are the CPU pins used exactly the same by each motherboard fit to use the CPU...?

Background to question... I used to run dual 604-pin Xeons on an old Asus PC-DL Deluxe board, and there were specific pin mods you could do to trick the motherboard into thinking it should run at 800fsb versus 533fsb, and such types of things. So now I have an Abit board for the same procs, and I'm wondering if the same pin mods will still work with this other board. I don't wanna test it and fry something without first getting a firm yes or no though...

Nope... they were intended to be used with 533fsb procs... or even 400fsb (603-pin). The 800fsb Xeons didn't come out until a couple years later. However, on a different forum dedicated to the Asus 604-pin Xeon boards, the PC-DL Deluxe in particular, a lot of modding avenues had been discovered, including a pin mod to up the fsb to 800, which, with a 2.4GHz, 18x multi CPU, comes out to 3.6GHz... and I know, that sounds like an extremely high OC, however the procs can be stable up there with the right amount of voltage, which would require another mod. Truth be told, I haven't got this system totally installed and up and running, so I don't even know what my motherboard's BIOS will allow with onboard overclocking features, but my guess is there aren't any. If I can up the voltage, however, I'll see what's possible... or lower the multiplier if I can. I have 6x 512mb DDR400 ECC Reg RAM, so just getting it up to 800fsb would be nice, even if I have to lower the multiplier because of a lack of voltage control. I'm looking for my mobo driver CD to open the manual and see if maybe there is a jumper, but I doubt it.

Mmmmmmm, old hardware. I was going to type out some extended advice, but I'd suggest you just read your own sig.

So, what motherboard DO you have?

Oh yeah, sorry, that might help... its an Abit WI-2Pa. The full system specs are in my list of systems...
