I am using a matched pair of Corsair XMS PC3200 currently running at 210fsb with 3449 timings and 1.8v. It is on an NF7-S with a Mobile Barton 2600+.

I was running at 211x11.5, and with my vcore at 1.81 and 3DMark03 kept freezing during the first cpu test... I raised the vcore and it still frooze... so I lowered my bus to 210 and it ran 3dMark03 just fine... I lowered my vcore to 1.81, and it passed... I bumped up my multiplier to 12 and it passed... so 210x12 @ 1.81 vcore passed six runs of 3DMark03 and about 2 hours of playing Halo and maybe a half hour of Far Cry... but Prime95 tourture test using 100% of CPU resources quit after 47 minutes or so... my temps never got above 45c

Yet with Prime95 running, my Vcore dropped from 1.81 to 1.79... I do not know if games cause the same draw... [BTW, 1.81 is when my bios is set at 1.825, and when I bumped it up to 1.85, and rebooted, my vcore kept flipping back and forth from 1.82 to 1.84, back and forth with every reading... but it doesn't do the flipping at 1.81] I am not sure what the max Vcore recommendation for the Mobile Barton is, but stopping at around 1.8 seems like a good idea for me... I am using a SLK900A with a 4800rpm 80mm fan set to 4000rpm...

I would like to get my bus up to 215. Heck, 2580MHz with a 1.81 VCore and temps in the middle 40s, I might even stop messing with this setup... :)

This seems like a ram issue to me...

Can my ram handle 2.9v?
What timings should I try next after 3449?

You ram sounds like what I have (see my sig). Most find that the NF7-S gets better performance with 2-2-2-11

The NF7 boards undervolt vcore. Mine undervolts by at least .025 and often .04. When OCing, my vcore bounces around a bit also.

Anyway, nice OC you got there.

Oh, here's a new website devoted exclusivley to the NF7 boards, might wanan check it out

Hmmm... I do not think I have tried that with this computer... on my other computer, I have a 512MB stick of XMS PC2700, and I tried it at 22211, and I had to reset my bios... it is an NF7-S also, but with a regular unlocked Barton... currently running at 200x11.5=2300 with ram at 3449 as well...

I will try 22211 on this computer...

Is 2.9v too high, if 2.8 is not enough... I do not have anything blowing directly on the ram, but there is a lot of air moving through my case...

2 and 2.5/2/2/11 do not work for me in prime95

what are some other settings I should give a try...

Right now, at 210 bus, 3449 failes prime95 blend even at 2.9v...
