DFI LP NFII oc with XP-M 2500+ + Kingston BH-5

[hoshy001]

Hi there,
i've got an DFI LP NFII Ultra B, AMD XP-M 2500+ IQYHA and Kingston HyperX with Bh-5
The Problem is I cant pass 240 MHz FSB.
I set the multiplier on 5x and all voltages (nearly) to the max.
In detail : 1,85V Vcore, 1,9V VDD, 3,3V Vdimm
And now I tested many different settings but I cant gat it stable at 240 FSB or higher.
Has anyone an idea whats the problem ?
- CPU too bad ? doesnt like the high FSB ? (it's not a very good one, 200x11 @ ~1,6V stable, 225x10 @ ~1,725 stable)
- mainboard limit reached ?
- Ram limit reached ?

but Memtest is running without problems at 240 (5-2-3-2) and above
and i think the LP Ultra B is also not the problem (i'm using Hellfire BIOS 3EG 1/21 Rev 3)

anyone an idea ? should I try another XP-M (2600+) ?
greets, hoshy001

does it boot up at all above 240 or does it hang with one led, or the low/high siren?

Have you tried running a fan over your fets?
Do your mosfets have heatsinks on them?
What type of cooling on the Northbridge?

I remember my old 8RDA used to scortch when it was overclocked.

mosfets have no heatsinks, cooled by fan little bit
but they are not really warm
nothbridge and cpu are watercooled by zalman reserator 1 plus
ram cooled by fan
