I have my XP2100+ maxed out now at 220x11.0 or 2410 mhz, 2-2-2-5, 2.8 VDIMM, 1.6 VCC (Northbridge?), 1.5 VAGP, and 1.87 actual VCORE. I'm not willing to go higher on the VCORE so forget about 2500 mhz. Upping the VCC or VAGP gets me no higher on the fsb. I believe the ram can do 225 fsb if the CPU wasn't so maxed out. Again, I am running a single 512 MB stick of Corsair XMS3500 C2.
I am totally stable here as I've passed a 28' SuperPI run. My benches: 3DMark2001 = 17303, 3DMark2003 = 5303, 3DMark2000 = 19944. Stress temps are 46 C as I am running an insane 5800 rpm 80 mm fan on my Alpha 8045. I am very very impressed with these benches, as to get the same scores on a P4 rig I have to run around 3200-3300 mhz, 180 fsb, and a Granite Bay DC board at 2-2-2-5. I am running a 9700 Pro at 375/335.
I have only been running Athlons for two weeks now and the only other board I tried was a K7RA-133R, so this NF7-S, 2.0 is very impressive, considering a newbie can get this far on an unmodded board and on air. I haven't even touched the stock Northbridge fan. I wil be putting the same CPU in an 8RDA+ and it will be interesting comparing boards.
