What is it that I'm not understanding about multipliers?

[GHoosdum]

I've got a TBred-B XP1700+ in my girlfriend's PC that won't OC above an 11.5 multi, but the FSB has a bunch of headroom, so I'm not at the limit of the chip's OC. Unfortunately, the board can't do more than a 180 or so FSB. Is there something about the chips that doesn't allow more than an 11.5 multi, or is it something about this particular chip?

Ehhhh...Rob

Board please?

[GHoosdum]

Oh. Sorry. It's the A7N8X-Deluxe rev 1.04.

i think u should beable to get 12.5 multi, if i'm not mistaken that the asus unlocks the multi all the way up to 12.5

[GHoosdum]

This same board allowed me to change the multis on my XP2100+ to anything up to 13.5... at any rate, I didn't think the XP1700+ was locked back then? It's a JIUHB DUT3C TBred-B... and I think it's #11 in the batch!

[TheLostSwede]

leishi is correct. Something's up with that bios i'm sure. Modded cpu in any way?

[GHoosdum]

Nope, no mods to the CPU at all - oh, and I forgot - the board only started unlocking multis when I updated the BIOS to 1006 and better.

[TheLostSwede]

Dammit, use that cpu in your own rig instead.

Do you use the latest bios?

[GHoosdum]

Yeah - it's been running so cool and low voltage at the 2.07 GHz it's at now I was considering switching the XP2100+ into her rig and putting the XP1700+ in my secondary... That way I'll just OC the XP2100+ back to an XP2700+ like I had it set up when that mobo was in the secondary and have done with it. And then I'll see what the little XP1700+ can do in my rig.
I think it's the latest BIOS - it's running BIOS 1007 right now...
