Help to raise fsb NF7-S

[Vader]

I am new here, sorry for my english, it´s not very good.

I am stuck at 236 fsb with mi Abit, and I want more.

Mi system is:

Abit Nf-7-S 2.0 236*10
Athlon Xp2400 L12 Mod
2*256 ddr 500 Adata Vitesta 3/3/4/9
Gigabyte 9500 64 mb softmod 9500Pro
Antec True Power 430w

I have sinks in the mosffets and in the sb, in the nb have the default cooler with artic silver 3.

I am using the 10 beta4 bios, but i tried others (223dfire, 22alpha1betakingturbo) and it is with i reach more fsb.

Voltajes are:

Vcore: 1,85
Agp: 1,5
Chipset: 1,5 (1,6 or 1,7 not increase the results)
Mem: 2,9

CPU Interface enabled, dual chanel (Slots 2-3), disabled enhance pci, spread spectrum, thermal throtling...

At 236 memtest report 0 errors, all works fine (3dmark, Aq3, Superpi) except prime95 test 1 run for 2 hours, but test 2 or 3 don´t run for 5 minutes.

More of 236 memtest report errors in test 5 and the system is inestable.

I reach to load windows xp at 244 fsb.

I don´t think that´s the limit is the memory, if i go to 240 with memory 4:3 (ddr360) happens the same, it don´t pass at 236 1:1 or 236 4:3

What can i improve for reach more fsb?

Nobody can help me?

You have reached a very good FSB speed for most NF7 boards. The only suggestion i have for you is to do the vdimm mod. 236 with 2.9v is pretty darn good if ask me.

...He is running PC4000 ;)

What are your 12v, 5v, and 3.3v lines mate?

... and i would think that's with quite loose timmings... :( PC4000 is not really best choice for AMD setups, on which tight timmings are the only way to go... besides 236FSB is not uncommon for NF7-S with such memory...

Mi volt lines are:

3,3: 3,25
5: 4,95
12: 11,90
