Can the Asus A7N8X change multipliers for the Barton?

[therealmitchmoyars]

as the title reads can I change the multiplier on a Barton +2500? I tried it with my T-Bred B +2100 with bad results..... that's why I'm asking. FYI I have a Asus A7N8X-Deluxe PCB 1.03. (first Nforce chipset)

yes, i have my Barton 2500 running as a Barton 3000 10.5 X 200 w/same board & latest bios. stable....
could'nt get 2.2 gigs (Barton 3200) stable
edit! bump volts to 1.75,
testing now w/double prime95

Even the first version of the A7N8X? I see you got 200 out of the fsb so I'm asuming you have a 1.06 pcb revision or later. Hmmm also how old is the +2500 chip? Did you just get it or is it a few months old?

200FSB isn't all that uncommon from 1.0x boards. Your 1.03 should be able to handle it, unless it's one of the very bad ones that doesn't supply enough volts to anything except the CPU.

topdog: Why are you double priming? Isn't that only for HT enabled P4?

You can select multipliers 12.5 and below only.

I just took another look on my board and it's acually a 1.04 pcb not a 1.03. I know Asus only says they give support for the 200fsb to the 1.06 or later but I had heard of people with older boards hitting 211. funny thing though..... Jeff7181 here (http://forums.anandtech.com/messageview.cfm?catid=28&threadid=1113337) says that the Asus only unlocks the 12.5 and lower multiplier. Even with my +2100 T-bred B processor it wouldn't work for me. I tried setting the multiplier to anything and it wouldn't work. Black screen then boot into the bios. Even when I set it really low it wouldn't work so I just used the fsb. Any idea why it wouldn't work. Also I'm using the 1003 bios. I plan on using the 1004.

**fast update** I just went over to Asus's site and now they are claiming a pcb of 1.04 or later will support the new 400fsb chips so I guess I should be able to hit 200 with no problems. About time I made use of my Corsair 3200!

I'm still a little puzzled about the multiplier issue though.
