Streaming issue? SimpleStream results not as expected.

When running the SimpleStreams test from the SDK it reports the following:
memcopy: 16.55
kernel: 18.31
non-streamed: 30.84 (34.86 expected)
8 streams: 28.98 (20.38 expected with compute capability 1.1 or later)

Test PASSED

As you can see it is almost as if no asynchronous streaming was done at all.
I checked that it was running on the GTX280 and not the GF8600 that I have in the system too.

I am running it on a Zotac GTX280 and GF8600, driver 177.41, XP64 on a Asus P5E WS PRO (bios 0802).
Cuda 2.02b.
CPU: QX9650 3GHz, 8GB ram.

The card is now working at PCIe Gen2 speed too.

Anybody else seeing that issue?
Any advice on what to check too?
Thanks.

Unfortunately i am having the same problem…
