Hey a7n8x 2.0 owners -

what kind of bus speeds are you getting to run STABLE on your board
with pc3500 ram?

I have the 2.0 board, mushkin level one pc3500 (2x512mb dual channel)
and a locked barton 2500 - best I can get to run stable is 214mhz bus
x 11 clock. (ram voltage - 2.8, cpu - 1.80)

anyone with this same combo? results? if you are using different ram,
what kind of numbers are you getting? cooling? voltages?

Barton 2500+ with TwinX1024-3200LL

220MHz, 5-2-2-2 @ 2.7V

It didn't work at 225, but I didn't raise voltage further.

Those are some great numbers.... what slots are filled, and with what?
what kind of cpu cooler are you running?

I've got a 9600pro in the agp, adaptec 19140 in pci3 and a 3com 56k in
the last pci. Cooler is an AX-7 with a 80mm smart fan, temps running
about 27-30 idle, 38-42 use.

Memory slots 1 and 3.

The devices in my PCI/AGP slots aren't really relevant but:
Crucial 9800 Pro
BT878 TV card
Connexant Modem

Aero7+ but I'm not running my CPU or RAM overclocked at the moment - it
doesn't like the high FSB and gets unstable, one day I'll get round to
sorting the CPU/Heatsink so that it's not so darn hot (it peaks at ~60°C at
stock)

BTW the memory is stable at that speed - I used memtest86 with CPU at
something like 220MHz*10 - no errors in two complete test loops. The errors
surface in Prime95, so I know that the problem lies not with the memory.

I would say your slots are relevant, as those can be your bottleneck
as well, can they not? Why slots 1 and 3, as opposed to 2 and 3 (the
blue ones) ?

Not really... only on boards that use a ratio to set the AGP/PCI bus from
the FSB, and even then, only when overclocking. The nForce2 has a seperate
clock for the AGP and PCI resulting in a constant 66MHz (or 33MHz) clock for
all your cards, nice.

No particular reason. Oh, and the slot colours change depending on the
phase of the moon or something.
