SB performance questions

[VirtualLarry]

I recently put together a micro-atx system on a NV6150 chipset-based mobo, and my SB scores seem low.

With an AMD Athlon64 3800+ (Venice) @ 2.4Ghz, I'm getting only about 1.47Mcems/sec.

(with different mobos with discrete graphics)
With a friend's overclocked 3000+ @ 2.39Ghz, I'm getting 2.6Mcems/sec.
With a friend's FX-55 @ 2.6Ghz, I'm getting 2.9Mcems/sec.

(again with integrated Intel Extreme 2 graphics)
With my mom's Celeron 440 (C2D) rig @ 2.0Ghz, I get 2.5-3.5Mcems/sec.

Is it the integrated graphics that is slowing my rig down? Is SB highly dependent on memory bandwidth? I am running in dual-channel.

I think I should be getting at least 2.4Mcems/sec.

funny you should bring that up, On my laptop I was getting 3.4M all the time, but with the latest test I'm only getting 2.0M I'm just wondering if it's double checking. Or if SoB changed something.

I'm waiting to see if my two clients on my E6850 will also show this once they get some new tests. One is at %91 and the other at %77.

My opinion is that you should be getting about 2.7M on the 3800+

Yes, they are doing double-checking at the moment.

So speeds are slow at the moment? My Q6600@3.0 is getting right around 12.0M
