Help with overclocking of venice and memory

[RoboCod]

Hi,

Ive been tinkering for sometime with the overclock now and have accepted a low but stable overclock for a while. I decided to try notch it up a bit today but finding a few problems. I have a few questions that need answering but 1st I best tell you my initial setup:

As sig with these settings in Bios:

Venice 3000+ @ 2.25ghz - HTT = 250 x 9, on 1.58v, at 28oC (SL-120 akasa amber fan)

OCZ3200 @ CPU-Z frequency of 160.7mhz. Timings of 2,2,2,5. Divider = 2/1.33 = ~330mhz DDR.

A few issues I need to resolve:

Quite simply the HTT cannot be increased beyond 250, it locks up upon booting. Is this because the chip is locked to 250 or is this a limitation of my cheap mobo?

The multiplier is set to x9. Where is the multiplier normally altered? If it is in the bios setup I dont think my bios supports this option!

Although I understand the ram timings are tight I have found that loosening them considerably seems to have no effect on how much further I can push the HTT up. 250 seems to be maximum, even on a higher divider.

Sorry for the same old questions but Im only a noobeh

Thanks in advance

You'll need to reduce the HTT multiplier if you want to go beyond 250, CP.

You see, I dont know how to alter the multiplier. Where is it?

whats the stepping of the chip?

I didnt take note before applying the heatsink. Which program could I D/L to tell me this?

I dont wanna have to pull my heatsink off

I think that means the following:

OPN: ADA 3000 DAA4BP
Package: 939 OuPGA
1.35V-1.40
65oC max
512k L2 Cache
Rev: DH-E3
CPUID: 2, FF0
Model: 2F, Venice

Nope, there doesn't seem to be anything in there. Ill have to stick with 2.25ghz for the time being and get saving for a DFI
