What motherboard is it?

Check Tyan

Have you yourself ever attempted to configure x8 individual single core/asic gpu's on Windows 7 x64?

that's kind of a silly question to ask me. yes, of course i have.

They have lots of Mbs, I need epixoip's one.

Hello epixoip,

I bet you have that is the reason why I asked you. Can you kindly answer the remainder of the question from this post for us?

If you can advise me of what generation of ATI GPU's, chassis model and driver set that you were successful with interacting with x8 gpu's within Windows 7 x64 it would be nice to know incase I ever consider the Windows route again.

Thanx

we have built several systems with 8x 7970 and 4x 7990 using windows 7 professional and windows server 2008, in the standard tyan chassis.

Im afraid these cards will not even work on the desired 1000mhz. Ive read many reviews and forum posts, these card barely works on max power even with game benchmarks and imagine that under hashcat. The R290x maybe isn't the best choice for bruteforcers.

Ok as for my experience with the dual asic cards and Windows 7x64 have been ok but have tested anything above the 6XXX series. It's good to see that the x4 7990 also functions. My interest lie in your windows configuration w/ x8 7970. As for this config of x8 7970 was that on your FT77 or FT72 chassis?

both.

Bringing this thread back on track, I've determined that most of the problems identified at the start of this thread are caused by Overdrive6. Or rather, the lack of Overdrive6 support in the current tools.

Using ADL SDK 6.0, I wrote a small program that I call od6config that controls the fan speed, clock rates, and PowerTune using the new Overdrive6 functions. It works great (meaning it actually sets & accepts the values appropriately, unlike amdconfig) so that solves most of those problems. Well, it resolves the fan speed and clock rate issues at least.

The problems still remaining are the kernel load time issue (20-30 seconds to enqueue a kernel), and erratic hashcat performance even when the PowerTune power control threshold is set at +50.
