Help with overclocking 3x Radeon 6990

post #1 of 34
Thread Starter 
Hi,

I'm usually not an overclocker, and I'm not a gamer either. I'm setting up a machine with the sole task of rendering 3D graphics (the program used for this is not really relevant).

I bought a MSI board with enough PCI-e slots to fit 3 Sapphire Radeon 6990's, a cheap SSD harddrive, a cheap AMD cpu and 4GB of RAM. I installed Windows 7 Ultimate x64 on this.

I've been building and working with computers since it was possible to overclock an 8086 by soldering a new crystal on the board, so rest assured the cooling and power requirements are all met (I removed the stock fans and used two 120mm fans (255 m³/h) to create a cooling tunnel through the cards, one push, one pull).

The rendering itself works great at stock speeds, but I would like to squeeze some extra performance from the cards by overclocking the cores and underclocking the memory, and here is where I'm hitting a brick wall.

The objective is to run all six cores and the memory at 900Mhz, seeing as the 'overclock mode' (the little switch) is 880Mhz that should not be any problem.

I started out with Sapphire TRIXX, which works fine when I:

-Uncheck 'Synchronize cards in Multi-GPU config'
-Manually specify the desired GPU and memory clock and click apply for each core individually.

This results in the desired speeds. However, when I reboot the machine, TRIXX will restore the earlier configured speeds only for the first core in the system (checked with GPU-Z), the other five cores remain at their default speeds.

If I do NOT uncheck 'Synchronize cards in Multi-GPU config', I can set the desired speeds for the first core only, and the second core will follow the speeds set for the first. The other four cores are not configurable. Sure I can change the slider, but TRIXX will reset to the default values immediately (I don't even get the chance to click 'Apply'.

Seeing as the machine is destined for 24/7 operation and reboots will be rare, I would not mind resetting the speeds for all cores after each reboot if it weren't for the fact that TRIXX does not function when you run it over a Remote Desktop session (which I will be doing). Over RDP, clocks for all cores are not configurable and show as zero.

So basically I cannot setup TRIXX to set the clocks on all cores automatically on reboot, and I can't set them manually after boot over RDP. Damnit.

Then I tried RBE, not knowing that ATI/AMD is apparently now using some PKI system to prevent flashing in clocks directly. After some BSODs and more reading on the internet I restored all cards to stock BIOS, back to square one. Damnit.

MSI Afterburner does not work, tried clean install, driver reinstall, all the usual suggestions I found, no joy here. Wrapper failed. Damnit.

Asus SmartDoctor says it can't control ATI/AMD 2nd VGA card. DAMNIT.

ATI's own CCC only detects two cores (or cards, can't really tell). Double Damnit.

This is just utterly ridiculous, all I want is all power management off, and the clock speeds at 900. When I started with this it sounded easy enough, but apparently there's n+1 utilities out there that either do not work or only work in a under very specific circumstances (which makes it even stupider seeing as every 6990 is the same but for the BIOS).

I'm ready to break a keyboard over this, so perhaps someone here would be so kind as to tell me how to do this.

there is a program called ATI Overdrive (related to AMD Overdrive). I have not personally used this but it seems to work for people. That is the only other GPU OC utility I know of. Though if your using this 24/7 for actual work, i would recommend that you leave them stock because 3 6990s crossfired is a already monstrous system. And a BsoD when your playing a game is annoying but a BsoD when you are doing 3D rendering work is a real issue. So to avoid possibly losing a large piece of work keeping them stock is best.

get ready to destroy anything 3D related. seriously rendering will be cake. This is coming from a mechanical engineer who is constantly bringing ideas and plans to life. ENJOY

I'll take a look at ATI Overdrive, thanks. Concerning the setup, they are not in crossfire. Basically this particular system will be doing CRC calculations for a different monstrous++ system that will do the actual frame rendering, and it addresses the cores directly and seperately. I believe what I want this system to do is comparable to doing protein folding.

In case the system crashes the main renderfarm will just do the CRCs that did not complete, hence the cheap hardware (other than the 6990's, those weren't cheap ).

Hmm, if I'm not mistaken ATI Overdrive is included in CCC. This is the utility that does not recognize either one card or four cores (drop down has two entries to select).

I think I'm complicating things by using one of the 6990's as main display device. I'm going to try putting a Matrox PCI-e x1 card in to see if that makes a difference.

exactly what I was thinking...
I don't even know how you would be able to connect them
