Sweet deal!

I picked up a Zotac GTX 580 for $75 on Saturday. Just plugged it in. While nvidia-smi reports a temperature of 72°, I seem to be experiencing some throttling as throughput starts at 424 GHz-d/d and drops to 409 GHz-d, even with the fan running full tilt. I'll have to try increasing the case air flow. My other GTX 580's will run into 90's before throttling.

Are you sure it is throttling? That sounds somewhat like what my 570 was doing until I tweaked the Sieve-related parameters. In my situation, there's no way the GTX 570 was running into the wall. The drop happened in the upper 50s to low 60s C.

Speaking of air flow, I just added a new side fan. It's a Noctua Industrial 140mm. I have to keep it on a tight leash. Its rated top speed is 3000 RPM, and it tops out at 2700 RPM. I am more interested in getting it to run between ~1800- 2200 RPM. Even a Noctua will snarl much higher than that.

I was going to say something about MSI Afterburner, but you run Linux, don't you? Whatever. If you can monitor the core clock in real time you'll see at once if it is throttling. IIRC, Nvidia chips throttle by switching between full frequency and their 405 MHz "2D" speed. In Afterburner the frequency graph turns to jagged mountains.

That was it! I was running a GT 520 in that slot. I had GPUSieveProcessSize=8 set for the old card, and not 16, and hard forgotten to adjust it. D'oh. Fixed now.

I had hard drives that spun that speed :D

Yeah, I do run Linux. Unfortunately, the clever utilities don't exist.

I'm seeing 797 MHz GTX 570's for $60 CAN now. Cheap for 419 GHz-d/d.

If only SLI power supplies were so cheap.

OK, I installed a new GTX980 super-clocked board on my old system running Linux Ubuntu 14.04 LTS.

Then I entered the Developer Zone to update the system, and noticed that users of GTX 9X0 were redirected to another section; downloaded the cuda_6_5_19 run package, then clicked on the link with the installation instructions.

I followed the instructions, updated the packages from apt-get and now my system is dead: after the Ubuntu 14.04 screen it freezes.

It seems that the repository automatically points to a version not ready for the GTX980. Now I have the correct .run package downloaded, but can't access my system.

Do you have any hints before I reinstall Linux and everything?

Does Ctrl+Alt+F2 work? (Ctrl+Alt+F7 to go back to X.)

It worked! The installation is complete, thank you for the hint (I had an old installation of 340 pending, after purging it the previous instalation completed).

Gaming-wise it's almost identical to the Titan X but for our own purposes, I think it's less good than the Titan X for LL. I'm sure TF will be similar. At any rate, I'll be happy to share results and run whatever tests anyone wants if nobody else is getting one.
