I agree, starting to feel the heat here in Miami too and it's starting to get warm!
The 7870's I have run nice and cool- mid 50's to low 60's at full load whether gaming or crunching and the cooler on them is nothing special. We have another month or so before it gets warmer here so I'll have the opportunity to run the 580's in the folding rig for the Chimp Challenge w/o cooking the house too bad.
May consider moving one of the FX rigs into the basement for the summer.... they warmed up my little home office quite a bit last year
Wish I had a basement to move them to. My place is small so get really gets to you LOL.
It was really weird not seeing basements or 2nd floors on most homes when I lived down in Florida...
Got a 1,200 mile extension cord? I'll run yours here if you like
Give me a few years, might have it done by then
My dad's home computer is still giving me grief. The GPUs always fail regardless of what driver I use, and sometimes the computer reboots itself and whatnot. It really sucks that I have been missing out on so many points, but my hands are tied without any spare systems right now and buying a new mobo is kind of out of the question atm.
What are the specs on the rig (psu incl.)?
Phenom II X6 1100T (stock) with Hyper 212+
2x4GB G.Skill 1333 CL9
ASUS M4A89GTD Pro/USB3 with disabled HD 4290 IGP
Crucial M4 64GB + Seagate 1TB on various ports and SATA cable changes
XFX and Visiontek 7770s stock, tried multiple drivers. Did same thing with just the XFX.
3 different PSUs tested: Corsair TX750, Corsair CX430 (w/ adapter) and now Rosewill RG530
Windows 7 Pro on the SSD
Basically this thing starts failing GPU work units like crazy after about a day of uptime. Sometimes it reboots itself and gets stuck on a screen reporting no bootable devices detected, and a simple power cycle gets it to boot up fine. Seems to be most likely to reboot during that first day that everything works. If it's left alone, the GPU WUs fail, BOINC reports missing GPUs or stops getting WUs, and it falls back to CPU WUs which appear to work just fine. This system has been temperamental even when my mom was just using it and before I ever touched it, although that was with Core Unlocker and TurboV enabled by my dad which ended up causing intermittent issues, but all that junk has been disabled for months.
Kinda sounds like the board, maybe the ram- not sure though....
I have an M4A79XTD Evo that I will likely be pulling to install another Biostar A880GZ board in the rig. I'm currently having BSOD issues with the rig but don't think it's the board yet. If the board isn't f**ked, I can send it to you to try if you're interested.
Drop me a PM to discuss if you like
I might consider it. Go ahead and do your board swap to see if it makes any difference, and if you think the board is alright I might as well try it I suppose. I can try swapping the RAM with another identical kit, but I don't think that is the issue (it's worth a try, though).
Definitely worth a try- had a couple of ram issues with my rigs recently
There's a nice Gigabyte 790FX UD5 for $50 here:
May consider picking up myself if it's still around a couple of weeks from now
Nice find - my dad's work computer has a Gigabyte 790GX board with a 1045T and it has been rock solid except for the Corsair TX550 or whatever it had that was apparently defective since the computer was built. It folds 2x GTX 460s 24x7 and crunches on most of the CPU during the night.
I've had a weird issue with the AMD 4P that if it was running too many Clean Energy WUs (10+ or so) at a time it would throw a "Computation Error" on all of the work in progress--obviously problematic. However, if I suspend the CEP2 WUs that it was doing and then only run them in "batches" of a few at a time, strangely, all goes well. Consequently, I've told this system to not get any more CEP WUs and I'm slowly running through the ones that are already downloaded.
You can set the max # of CEP2 running thru the WCG profile page or set a max concurrent # in an app_config entry. iirc there is an issue with that wu throwing errors when too many are running (search WCG forum- I believe I saw it discussed there)
Well, I have the WCG page set to give my other systems unlimited WUs, as it isn't problematic there.
The app_config is a good plan, however, this system does even worse on CEP2 than most anything else, so I think I'm just going to leave it crunching other projects.
Interestingly, the 3930k will do ten or twelve CEP2 WUs just fine--I wonder why the 4P won't.
On two of my systems, I has issues with stability. One is an AMD rig with a Phenom II 910e not being able to run more than one video card. The one that's in there runs eight WU's perfectly fine on a 7770. The other rig is a Q9300 that can't run four GPU WU's at the same time, but can run at least two. Still playing around with it.
Try a lighter load on the GPU if you're running multiple WU's.
I finished the OS install/updates on the Xeon hex-core/2x GTX 580 rig and set it crunch for awhile.... man these 580's throw heat like crazy
Temps are in the lows 70's with gpu wu's running and mid 30's at idle (don't know if this is normal w/NVidia cards?). The wu's finish in about 6 minutes so not too bad there.
I'll let it crunch for a few days to make sure it's stable before I switch it to F@H for the Chimp Challenge
Yeah, tell me about it, these GTX470s throw off an enormous amount of heat. That and they're just damn loud too
Welcome to Fermi GPUs. I hope the GTX 660Ti I will receive in a few days performs "decently" in F@H so I can start downsizing my Fermi collection.
Ehh, I'd say that the GTS450/GTX460 and GTX550TI/650/TI/TI448 aren't that bad--it's the GF100 and GF110s that are brutal
The GTX 670 (MSI OC reference PCB model) I had for a little while ran in the low 60's while crunching gpu wu's and the heat thrown out of the exhaust was nothing like these 580's .... less than half if I had to guess.
Correct, my GTX 465 and 470 (both GF100) are the worst offenders. GTX 460s still have the potential to be close to 200w GPUs if overclocked enough, and my GTS 450s aren't too bad either.
Hmmm wonder whats up with my 5770, Its been running for two days at 2 WU's and only brought in alittle over 4K today when it was getting 17K when it was at work?
Are completion times the same? No errors?
First 7870 is in customs. That was fast
