I upgraded my GTX 1050 ti to a GTX 1080 FTW in a prebuilt Dell XPS 8900. When upgrading the GPU, I replaced my PSU with a 750 watt PSU. I started getting intermittent stutters when gaming after these upgrades.
I looked at my temps and noticed my CPU temperatures were hitting 80-85 celcius under load. I thought this was my problem, so I swapped out my heatsink to a closed loop liquid cooler, swapped to a new case with more airflow and added an additional fan.
The intermittent lag is still happening after normal temps now, and I noticed my CPU is hitting 100% randomly with games, which wasn't happening prior to upgrading the GPU.
Other data points: I do stream on Twitch, but it was not causing issues prior to the upgrade. 16 GB DDR4 RAM.
Any help would be greatly appreciated. This one has me stumped.
Edit: As requested, here are some more details: PSU is a Corsair CX750m. The temperatures during 100% utilization are around 65° C after the addition of the liquid cooler. Graphics drivers are the newest GeForce Game Ready drivers. In-game settings are what GeForce Experience said was optimal. The stutter seems to happen when the spikes occur.
I thought I included it above, but my CPU is an i7 6700k.
1Please post some detailed specs. What brand is the PSU ? What temperature is the CPU at when at 100% load ? What driver version do you use for the 1080 ? – Overmind – 2018-07-26T06:03:40.907
1Did you change the game settings? You might've been GPU limited before and now you're CPU limited. Do the 100% spikes accompany the stutter? Also check your streaming settings to use the proper encoder. What CPU do you have? – Seth – 2018-07-26T06:40:57.387
I've updated the post with the requested information. Hope this helps. I wouldn't think I would he CPU limited since I'm running an i7 6700k. – Brock B. – 2018-07-26T11:50:45.677
Now that you upgraded the graphics card, the CPU is probably the bottleneck for whatever you’re doing. Due to bugs or misconfiguration the CPU may not run at full frequency. Did you check that yet? HWiNFO64 can for example log both frequency, load percentage and all other relevant values. – Daniel B – 2018-07-28T08:36:28.453
The latest bios update kills this machine, so dont update it https://www.dell.com/community/XPS-Desktops/XPS-8900-BIOS-2-2-1/td-p/5645475
– JohnnyVegas – 2018-07-28T09:00:07.667Does this apply to all gaming? What about other graphical stress? Does this happen when doing a benchmark for example? If you now change back to 1050, does this happen then also, or is it back to normal? – Aulis Ronkainen – 2018-07-31T06:05:09.273
I haven't tried a normal graphical benchmark. I'll try that today. I also haven't tried swapping back to the 1050, but I have a sneaking suspicion my issue will go away when I do. – Brock B. – 2018-08-01T13:54:11.473
