560Ti doesn't perform correctly.

Hi there,

I cannot fathom what the issue is, the gpu runs at full load on games which is fine but performs poorly and doesn't get hot. It suggests to me that the gpu isn't getting the required voltage but its odd to say my gpu isn't getting hot enough at full load.

Skyrim runs at full load when the card is having its performance issues and runs at 42c. On a normal session it runs around 60c and fluctuates depending on the environment. 30/25fps average when the card isn't performing correctly and constant 60fps when it is performing optimally. On normal sessions fan speeds increase when temperatures do but when performing oddly it doesn't change.

I was first led to believe it was Afterburner giving incorrect readings but speedfan and other software has matching results and it correlates to the issues.

Is it a PSU issue? I cant find much info on this issue, maybe am being too specific and looking into the wrong area it's just peculiar.

Any ideas? Thanks.

Oh, I haven't overclocked the card and cpu is overclocked but has ran healthy for a long time.

Prof Kerfuffle,

Use extreme Power Supply Calc to get an estimate. Looking at your specs I'm thinking you are probably close to the limit for your PSU, so that might be the issue.

I did that calculator before I bought the new parts and yesterday, came to around 500w which is 100w to spare which sound normal. Realistically it will probably be a little bit more than 500w but I dont have that much plugged in my pc anymore. I used to have around 4/5 HDDs so my listed specs arn't 100% accurate.

I think the psu is a little bit under powered regardless, am not sure how accurate the calculators are.

Okay, you could try removing a few things, IE the second vid card and any extra hard drives and see if it changes. That 560ti card is a good one, however moving up to a newer gen card might help too as they use less power. I'm not suggesting and upgrade just yet, just ideas to maybe see if it is a power issue.

Have you tried updating your graphics drivers to the latest ones, its best to uninstall old drivers then run Drivers - Clean Left over Files after Uninstalling then install new drivers from here Drivers - Download NVIDIA Drivers

I see what your trying to say but again, I have 2 PCIE cards (GPU & NIC), 1 HDD, 1 SSD, CPU Cooler & fans, 2 DIMM sticks. A new gpu isn't ideal right now and yes newer gen of gpus consume less power, I noticed it from my old cards but anyway. The problem occurred when my system was running with the components above just with the extra few fans.

Just to clarify, I've re-seated the 560ti, checked PCIE power cables, checked modular connectors, plugged in cpu cooler fans. My pc is currently running fine with the GPU @ 46c which is normal for idle on my card. When performing like crap it runs at 36 and is throttled. *(presumably by power issues)


(My 450 is rarely used, only when I need a 3rd monitor)

Yes, tried 320.00 beta and 314.22, no difference and that was the first thing that occurred to me. Just Cause 2 wouldn't play above 10fps on my standard settings.

I even rolled back and still no luck, am guessing it's a hardware issue here

Hopefully not. Do you have a friends rig you could try it in to rule out the card?


Edit
Wanted to add even though you said you tried the nvidia drivers, are all your motherboard drivers, dx, etc up to date. This Nvidia Tweak Guide is a pretty go read to help optimize

You know that never occurred, I was preoccupied with one thing I lost focus

I have a spare rig (somewhere), I will report soon with the results (although not today, its getting late for me)

Thanks.
