Except for the initial header that shows your configs, logs are unlikely to show much, if the GPU WU will Fold fine alone. It sounds like more of a computer problem, whether configuration or heat. Post that part of your log here within thetagsCode: Select all
Ensure you have 1 CPU core free for the GPU; use the F@H client to set the CPU slot to 7 cores.
A description of your case and cooling setup, possibly with pictures, might help.

tags, so just let me know. As far my setup, I have 4 fans, 3 crappy blue LED ones and the Noctua which is right above the CPU in my photos. The other two crappy blue LED fans are on the front side of the case, where the optical drive, SSD, and HDD are located. Everything is connected to a silver rated 750watt Solid Gear Neutron PSU. Let me know if you have any more questions, btw I also added you on skype if you want to chat (and if anyone else wants to, PM me your skype (or steam name)).
[quote="bruce"]The TDP of the 280X is 250W and the 290X is 290W. This you're probably adding 40W more heat than you were ... and drawing 40W more power from the power supply.
You said you could run the GPU on full with the CPU slot paused. Was that the 290X? Most likely you're right at the maximum power your P/S amd/or your fans can handle and adding the CPU, too, is just too much.[/quote]
on my 290x I could run both the GPU and CPU on Full. On my 390x, I can only run them on Light. Anything higher than Light causes shutdown. When I was shopping around for GPUs, I was informed that my 750watt PSU would be more than enough to power it as well as all my other components, but I guess maybe that's only true if they're not running at 100% power draw?
[quote="7im"]And or one of the rails is overloaded if that PSU has more than one.[/quote]
I'm not really sure what that means :(
[quote="Nathan_P"]Definitely sounds like the PSU to me, the fact that the old gpu can fold with the cpu and not both together with the new gpu installed is a major pointer. Personally at this point I would go out and buy a decent PSU from your favourite e-tailer and by decent I mean a big name brand - seasonic, corsair, superflower etc.
Before you buy though check out some reviews from a tech site, if you want some recommendations drop me a PM.[/quote]
The thing is is I already spent a lot of money on this rig. Maybe I should just run it on GPU-only? Does the CPU really contribute that much? Anyway, if you have some recommendations, I'll look into it. The only problem is that I would have to sell my PSU after, and I hate using ebay (maybe craigslist or facebook groups would work better). Anyway, I'll consider it.[quote="jrweiss"]I am surprised that a 750W, Silver rated PSU can't put out 350-400 Watts or so. OTOH, there are a lot of bad reviews on it on Amazon...
If the OP gets CPUid HWMon running, he may be able to monitor the 12V rail voltage stability while testing it...[/quote]
I think hwinfo does this.. do you want me to take another screenshot of the log?
[quote="wilding2004"]The 750 figure is probably just the maximums from each rail added together. Admitedly not many manufacturers still do this, but there's always some that will. I doubt that PSU can actually deliver anywhere near 750w. Just had a quick look on google, and that model only has an efficency of 78%, so it doesn't even meet "bronze" certification, never mind silver.[/quote]
It's rated silver.. is that just a straight up lie? It looks like my options are to get a new PSU or just run it as GPU-only.You know, now that you mention it... I just took a look at the box and I see no rating anywhere. Nor did my search online bring anything up. This whole thread I've been saying "silver rated" for some reason, but I have no idea why. Maybe my friend told me it was silver rated and I just believed him? It looks like I need to get a new psu!Rel25917 wrote:Try GPU and CPU and see what your 12v reading does. It's dipping down to 11.8 with the gpu load which isn't too low but if it drops further with the cpu load added then the power supply can't handle the load.
As for the supply itself a google search seems to indicate that it is a single rail but where did you get the silver rating from because i'm not seeing that?
It has a single 12v rail, but it still has mutliple rails for the other voltages, 3.3 5,etc. I was sugesting that the 750w figure comes from combining the total load at all voltages. This used to be standard practice, but thankfully manufacturers are a lot more honest today about their PSU's capabilities.Rel25917 wrote:

That alone is a key that it is NOT a good PSU. Any modern PSU worth its salt will have a 12V rail rated to [very near] the full output of the PSU. Most of the power taken on modern computers is from the 12V rail.Rel25917 wrote:The specs indicate 600w available on the 12v rail. Should be enough if the supply is working right but its looking like its starting to struggle with just the gpu load on it.
