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