Posted April 2, 2017 Hi guys, recently I bought new computer parts that I put in all together. However, since I'm yet to order a GPU, I have moved one from my old PC to new PC. Now the problem I'm experiencing is this: on new PC the GPU will never go into full work, no matter what I do. This results in a lot of fps stuttering that I didn't experience before (on old PC) and games basically become unplayable. Some raw data: when playing Overwatch on old PC my GPU's temp stays in 81-82C range all the time. On new PC it never reaches more than 76C, usually staying in 71-74C range. Max fan speed was about 2300 RPM on new PC, which according to GPU-Z is barely 57% of max fan speed. I tried literally every single thing I found on the internet, but still nothing - installed all the latest drivers, tried the old ones, updated BIOS, changed power settings (both windows' power options and nvidia's control panel), ran applications as admin and others. Old PC specs: CPU: i5-4570 GPU: GTX 660 Ti Motherboard: MSI B85M-E45 RAM: 1600Mhz - 8gb New PC specs: CPU: i7-7700K GPU: GTX 660 Ti Motherboard: MSI Z270 Gaming M3 RAM: Corsair Vengeance LPX, DDR4, 2x8GB, 3000MHz, CL15 - 16gb If you have any idea why this might be happening, please help me.

Posted April 2, 2017 Did you do a clean install of your video card drivers? Have you been monitoring GPU usage and clock frequencies on both builds?

The issue is that it's working way worse on the new PC than on old one. 4 minutes ago, Godlygamer23 said: Did you do a clean install of your video card drivers? Have you been monitoring GPU usage and clock frequencies on both builds? Yes, clock frequencies stay the same on both builds, GPU usage is less on new PC I think, gonna make sure of that in a sec. I did clean install of GPU drivers, but I didn't even have to - the issue is there since the first time I installed them (newest nvidia driver, which is installed on my old PC aswell) Link to comment Share on other sites More sharing options...

Posted April 2, 2017 ive heard of older nvidia and amd gpus running on windows drivers even though they had installed the new ones from geforce or crimson. also id consider turning off ambient occlusion in your games aswell and check to see what drivers it says its running in GPU-Z.

Posted April 2, 2017 Looking at fan speed and temperature is not how you determine how much your GPU is working. There's this thing called "GPU usage" which tells you at what percentage it's working.

What software issues? everything is basically the same.

There's this thing called "GPU usage" which tells you at what percentage it's working. Yea I know that but all are related. Just checked now and on new PC GPU stays in 54-74% usage range, spiking to 90-95% periodically. Basically what I see is the following flow: I get pretty bad fps, then I see GPU spiking to 90% which is when I get normal fps and ~~76C temp on GPU for a second, then I get stutters and temperature drops back to 71C, usage to ~~60%.

Posted April 2, 2017 download msi afterburner, its monitoring stuff will tell you temps, fan speed, gpu usage, gpu clock speed, and memory usage and you can see if it's getting stuck somewhere.

Posted April 2, 2017 Look at the GPU load next.

Posted April 2, 2017 Author 38 minutes ago, Majestic said: Look at the GPU load next. As temperatures are not really the metrics you look for when determening performance Temperature wouldn't be a good metric if I was testing just single PC build. But since I'm using same GPU on two different builds which do not differ in terms of cooling system, and I know that my GPU is a bottleneck, then I know that when I get higher temperatures on one build and no stuttering + lower temperatures on other build and stuttering that GPU is not performing optimally. You can see what I mean here: GPU usage is just spiking back and forth in 70-90% range, temperature never exceeds 75-76C. I might record on old PC tomorrow if I don't manage to fix this.

Look at what the coreclock is doing instead. Pascal Undervolting topic, get more out of your card with less power!

Look at what the coreclock is doing instead. Ok I guess you are right that usage is at 99%, but what do you mean by 'look at what coreclock is doing'? Isn't that the number on the far right? It just goes into boost mode and stays there all the time (1058Mhz) Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

It just goes into boost mode and stays there all the time (1058Mhz) Yeah i missed it, I have a custom layout of the numbers myself. Well to be honest, I'm not seeing anything weird happening. Maybe put the monitoring frequency at 100ms (in the settings) and monitor what the frametimes are doing. But from what i'm seeing, there is nothing odd happening.

Posted April 2, 2017 Author When I join game and temperature is still low (60-70C) the power metric is perfectly fine (97-100%). So for the first 10-20 seconds I get no stutter at all, when temp reaches over 71C power starts to drop and spike all the time. I'll reply tomorrow afternoon with more analysis and maybe videos Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted April 3, 2017 Author Took some screenshots of charts during unigine valley benchmark. The first screenshot shows benchmark with automatic fan control, 2nd and 3rd are showing fan set to 80% all the time in MSI Afterburner. The only difference is that power spikes start happening much later with custom fan speed, but overall it's pretty much the same because any power spikes, even small ones, are causing fps changes which makes game unplayable.

Posted April 3, 2017 Raise power limit and a little voltage. Prioritize power over temp. Turns fans up accordingly.

Posted April 3, 2017 Author Does not help at all. Raised power limit to 123 (max) and voltage by 25mV. 1st screen is just 110 power, 2nd is 123 power and +25mV, 3rd is 123 power, +25mV and full fan speed Link to comment Share on other sites More sharing options...
