k7n2 delta L + overclocking

hi,
i have the k7n2 delta L motherboard and an athlon xp 2600 (the barton model) and i don't seem to be getting very far with overclocking

i have high performance memory timings on and the fsb/dram in 1:1 (voltage is at stock), but i cannot get my fsb over 180 (it is unstable even at 178 in prime95)...

as for my ram, i think it's pretty cheap, but works well at 400mhz. the brand is "nanya technologies" which i have never heard of

if i don't overclock, the system is rock solid at stock in prime95...but i do only have an "encer" 300w psu and -12v does drop a little under load lol

am i doing something wrong? does anyone have any suggestions to improve this overclock??

thanks

you need a psu with 16a plus on the 12v rail

especially with newer vga cards as they and cpu are powered of 12v rail

New PSU like wonkanoby said, up the Vcore a little

XP 2800+ @2500MHz

Yesterday I managed to run my system

K7N2 Delta-L
Amd Barton 2800+
2x512 Infineon PC3200/DDR400 CL2.5

at FSB 200 MHz (200 * 12.5 = 2500MHz) with 1.8VCore and 2.7VDimm.

Unfortunatley it was very unstable so I switched back to FSB 192 MHz. Temps went up from 40°C idle to 50°C. I don't know what components are limiting the stability in my system at that level of overclocking, there is more than one possibility:

1) CPU: Well, I think I got lucky with it, but it might need better cooling. 1.8VCore is max on the board and I won't go higher.
2) RAM: Can't raise VDimm above 2.7V, maybe more could make it more stable
3) Mainboard: The MOSFETS get really hot and they are only cooled with passive heatsinks

PSU is no problem in my case

Bios for more Vdimm voltage. Its not ram voltage its Vcore that is holding you back and there is no Volt-mods for this board either.

I'm still running my old K7N2 with the settings you see in the sig. Like T-A said, you need a robust PSU and like Gulinborsti speculated, you need some decent cooling. I set up a VMOD 7V 80mm fan mounted on the waterblock mount to cool the passive heatsinks and it made a for a dramatic improvement in stability on this board.
