Hello all,

I have 2 256mb sticks of corsair xms pc3500 v1.1 with the bh-5 chips...

Can any of you confirm that my wall I am hitting is mobo bios or board related?

I can do dual channel at 2-2-2-10 with 2.7v @ 440fsb. In single channel mode, I likewise top out at 220fsb, and each stick tops out around 220fsb.

With the additional volatge to 2.9 (overvolted to 3.04 by nf7-s) I can only get to 225fsb at all configurations. Likewise I can get to 225 with 2.5-3-3-7 single channel timings... but any looser timings or any higher than 225fsb I get no post.

I am using 12 as multiplier and I know its not cpu headroom I am limited by. I test prime95+3dmark01 at same time stable after 5 hours at 2.7Ghz @ 1.875v 46C load... (waiting on fans to install water setup).

I read somewhere that there seems to be 2 batches of the boards.. some that do 215-220 and no more, and others that can go far beyond.

Is there a bios for the NF7-S that I can try to get better bandwidth? I am using a sata boot drive so... I know that limits my options.

In case I wasn't very clear my relevant specs are:

Abit NF7-S v2
AMD Mobile Barton 2600+ (my 2400 also capped at this fsb on this mobo)
Corsair XMS pc3500 v1.1 BH-5 2-2-2-5(10 if dc)
PC P&C 510 Deluxe (rails are 3.31, 5.08 12.11 rock solid)
Chipset has stock active cooling, no other heatsinks yet (i don't wanna add $40 in BGA and mosfet sinks on a 220 max board)
Chipset voltage at 1.6 and 1.7 same results.

All these results were in open air on desktop. Currently using a well mounted Alpha Pal 8045 and 80mm 83CFM Tornado. A 2nd 80mm Tornado blowing across the ram and chipset.

I currently don't have another board to test either the ram or cpu's fsb capacity

Any suggestions will be appreciated!
