Guide to changing multipliers on Barton cores?

[MrCoyote]

I have a Gigabyte 7DXR mainboard which only has a maximum of 133(266FSB). I know the new Barton cores run at 166(333FSB), but if I change the multiplier, I should still be able to get it up to speed while leaving the FSB alone. Other people have had success running a 2500+ on this mainboard by changing the multiplier, so Barton cores will work. Oh, and I really can't overclock my FSB higher than 133(266). My PCI devices can't take it. So what other CPU besides the 2500+ would be good to use? Would 2800+ or 3000+ be easy to change multipliers on?

I need a guide or something explaining what L3 bridges to change for the new Barton cores, like the 2800+, 3000+.

I would think that it would be a waste of money to buy any of those 3 processors.
2500+ = $95
2800+ = $175
3000+ = $250
(Newegg prices).

Instead of messing with L3s to try to get a Barton to run at 15 x 133, buy an 8rda from newegg for $83 and a (cross your fingers) 1700+ TbredB for $49 and sell your Gigabyte for around $30ish on FS/FT or ebay.

If that sounds like too much work, you could always try the guides here for changing multis.

I'm still a bit skeptical of the Barton performing well in that board. Even my 333fsb epox board will not officially support the Barton. Something about the L2 cache or something.... someone smarter than I am may be able to shed some light. People are doing it however, like your Gigabyte. So what the heck do I know?
