Based on our "rates" at work, you'd probably have 2 work weeks to get it running (and also keep it running!). Otherwise the Tesla solution would be cheaper already.
And that's just considering the cost for 1 person, no resources included. The effective duration would be shorter.

The Tesla solution is not that expensive for a company, big or small.

I've worked for some small companies that would disagree. I mean, he does have 7 GPU's running. Just having issues with that 8th.

Have you tried updating the BIOS? Maybe contact Tyan?
http://www.tyan.com/support_download...el=B.FT72B7015

Thank you for the link, I will contact those guys to see if they could resolve it.
Tyan - yes, sent them a question, waiting for the answer.

Solution is found, thanks to Tyan support. It is a bug in Win7, system has problems related to RAM counting.

Say, there are 72 gigabytes of RAM installed.

1. Run "msconfig"
2. Click "boot" tab
3. Click "advanced" option
4. Check the "max memory" box, the max memory field will automatically put "73728" (72GB)
5. Enter "72704" and apply the changes, restart the system, the system will run at what appears to be normal speed

The key basically is to change the max memory from whatever it shows to 1GB less than what it shows (subtract 1024).
This will insure proper operation of the system regardless of the total amount of memory installed.

Awesome, glad you got it working.

No problem. When I first read your thread, I thought it had something to do with the system memory, because I've never really seen a Windows 7 install running with so much RAM. The MS specs say it can, but I've never seen it tested.

Despite suspecting the memory as the culprit, I would have never guessed the solution in a million years, though.

EDIT: So, does that fix mean you're not utilizing all 144GB of memory?

Yes, this fix decreases the amount of available memory reported by system to about 140 gigabytes.
