Okay, I'm back from the Monkey's dungeon. That Interrogation Rm. #3 is one cold mutha. Fortunately, I was able to slither out while they were all in a banana induced stupor. On my way I snagged an MSI Twin Frozr Gaming GeForce GTX 750 Ti. I know I was warned against such folly, but the heart wants what the heart wants. So, here's the real deal Holyfield for anybody that was wanting to know. I had a hell of a time trying to find good info, especially numbers, online so I figured I'd put some up. I don't know why it should take 3+ months for somebody to do something so simple, unless I just didn't find the right place to look. Anyways, here goes:
MSI Twin Frozr Gaming GeForce GTX 750 Ti @1337Mhz (MSI Gaming OC to 1202+Afterburner additional 135Mhz, this is the Boost clock I'm assuming as it's running full-bore Folding. Not bad seeing as reference base clock rate is 1020. It's running about 94% of it's power envelope (no overvolting possible, PCIe slot power only). I didn't touch memory clock or anything else. Driver version 322.17 F@H client version 7.4.4. I don't SMP fold on this machine. As of right now Maxwell only gets Core_15, Core_17 is still unstable as far as I know. No QRB on Core_15, so the base and estimated values are the same. These are the only WUs I've observed so far, I will update.
WU 7620(47,0,36) TPF 6'20" Base/Estimated 5187 PPD 11794
WU 7622(258,0,107) TPF 6'20" Base/Estimated 14093 PPD 32043
WU 7622(493,0,215) TPF 6'20" Base/Estimated 14093 PPD 32043
WU 7626(105,0,212) TPF 6'25" Base/Estimated 14093 PPD 31626
WU 7621(531,0,228) TPF 6'20" Base/Estimated 5187 PPD 11794
WU 8018(10,0,471) TPF 5'04" Base/Estimated 5757 PPD 16362
Total time per WU has been around 10.5 hours. So, it'll do two WUs a day for about 20-30K. I haven't put the Kill-A-Watt on it yet, so I don't know about power consumption, but it has to be less than the hardware I'm using this to replace, and a shit-ton more points, too, so this was a good deal for me. I got this card off ebay for $120.00. I think it's the best version out there. If it saves me $10/month in electricity it'll pay for itself in a year. If it keeps netting me ~30K I might end up stopping my old dual-proc server, that would save me $20-30/month. Runs cool (about 55C so far, we'll see as ambient temps go up) and whisper quiet. Originally I wanted EVGA's basic model, new for $140.00. I think you'll hit a power wall before you hit the wall on clock speeds (I think I read that 60W is a hard limit, with or without a six-pin), you can OC the crap out of these bastids. I had a bitch of a time getting it working, first the crappy old mobo I wanted to put it on (Asus M2R32-MVP) just doesn't seem to have the resources (memory address space? IRQ's? getting a little out of my depth there, I tried running it with only 1GB of RAM and only one HDD, no other add-in cards, still no joy), so I put it in an old Dell OEM box. I got it to work, but only with driver version 322.17. And there you go.
