550W for 980ti? oc

[Leon538]

Hello,
i bought a 1070 this Thursday. i was really happy until i started looking at the fps and gpu usage. i then realised that i was getting the same performance as my old 970 because the usage was at 40%. i am not going to wait for a driver update in 5 months that might fix this so i want a 980ti.
specifically the gigabyte gtx 980ti g1 gaming. i have a 550w psu and am not sure if it will be enough to power the 980ti. i am also planning to oc.

Specs:
CPU: Intel Core I7-6700
GPU: Gigabyte Gtx 1070 Windforce OC
SSD: Samsung 950 pro 512GB
HDD: Toshiba DT01ACA Series 2TB 3,5" SATA
Motherboard: ASRock Fatal1ty Z170 Gaming K4 Mainboard
Ram: 16GB (2x 8GB) Crucial Ballistix Sport DDR4-RAM
Case: Corsair Carbide Series 200R Kast
PSU: Thermaltake London 550W 80 Plus Gold
DVD-Drive: LiteOn iHAS124-14 Brander
Cooler: Cooler Master Hyper 212 EVO

it is recommended that the 980ti is with 600w, i think you should be fine with 550w if not you can always upgrade psu also my friend has the same 1070 as you and his is fine apart from coil wine, maybe you can send it back to gigabyte for a new one?

 

[Darthutos]

you think your 980ti will be better than a new model such as 1070? why? according to gpu hiearchy here they are the same tier. why would you think 980ti would give you better fps?

 

[Leon538]

@darthutos well my 1070 gets about the same performance as my 970 in a decent amount of games (no, not cpu intensive) so i presume that the 980ti will be faster (also, it seems that it overclocks way better).
@henry28 ill contact gigabyte but there have been a lot of people with this issue, nvidia doesn't want to adress the problem because it could mean less sales (that's my theory)

That PSU is not all that good quality wise and I would not trust it under the load an overlocked 980Ti would put on it. a 1070 and a 980ti will trade blows with the 1070 usually leading by the end(especially if its oc'd). What driver version are you using? Did you get it from Nvidia or Gigabyte?

 

[Leon538]

i got it from gigabyte, driver version: 381.65

Something is wrong with your build, and you're not going to fix it by side-grading to a 980Ti. Instead, you should look into actually troubleshooting the problem. It could be a number of things such as Window's power options running the CPU at a much lower rate than intended, or it could be your motherboard's BIOS at fault.

Also, you haven't provided any evidence to support your claim of having "about the same performance" as your old 970 just because of under-utilization. You should run some benchmarks alongside some monitoring software (e.g. GPU-Z, MSI Afterburner, etc) so you can report GPU utilization, clock speed + voltage, and while you're at it, you should mention specific games (and the settings they're running at) where you are experiencing these issues.

i have some benchmarks that i did this afternoon:
Train simulator:
Gtx 970:80% usage, Didn't measure clock speeds, average 55 fps
Gtx 1070: 38% usage, core clock: 1555 mem clock: 4000, average 60 fps

omsi 2:
Gtx 970: 65% usage, didn't measure clock speeds, 40 fps
Gtx 1070: 39% usage, Clocks about same as train sim, 39 fps

Gta IV with LCPDFR:
Gtx 970: 75% usage, didn't measure clock speed, around 50-55 fps
Gtx 1070: 42% usage, clock speed same as train sim,60 fps

I don't understand the problem, because the clock speeds are normal but the usage is abnormally low

Well I'd go to geforce.com and download the driver from Nvidia, then get DDU, run DDU and usie it to completely uninstall the current nvidia drivers and software from safe mode, restart and install the driver you downloaded earlier.

 

[bignastyid]

What was the per core cpu usage? cpu clock speed?

 

[Leon538]

didn't measure per core usage but total cpu usage was Always about 35%

Alright so, given that your performance range is sitting abnormally close to the 60FPS line, I'll point out the obvious just to make sure: is VSYNC on? And if you've already checked in-game, have you also checked in the Nvidia control panel to see if it's being forced on?

 

[Leon538]

vsync is not on in game, also not in the control panel

 

[Darthutos]

in the nvidia control panel under vsync is it in the off position? adaptive and half would also vsync automatically.

at this point is there anyone who know how you can force gpu 100 percent utilization all the time in all games?

Have you tried setting the Power Plan to High Performance in the Windows Power Options menu?
Also, try setting the GPU power management mode to Prefer Maximum Power in the Nvidia Control Panel.
Now that you've checked the GPU clock speeds during load, you should try looking at your CPU's reported speed as well. As I mentioned earlier, it's possible that one of the (or a combination of) options for power management may be leaving your CPU running at a much lower clock speed than usual.
