A little help with overclocking?

[Bradley Lind]

Hey guys,

Just installed my new EVGA 1070 FTW Edition, the card seems great but am having a little trouble with understanding the overclocking (I usually buy pre-overclocked cards, like my last card was 280x Windforce OC Edition)

I have overclocked my settings using MSI afterburner, and when playing Fallout 4, I only seem to get around 40-50fps, despite my card *not* being at 100% usage in any way and generally seems to be at half usage (The max it hit was 68% usage while the game is maxed settings @ 1080p)

My rig:
i5 3330 @3.00GHz
16gb of Corsair Vengeance RAM 2400MhZ (although underclocked to 1600MhZ)
MSI H61M-P31/W8 Motherboard
GeForce Gtx 1070 EVGA 8gb (But for some reason Speccy only sees it to be 4gb)
Windows 10 Pro

Here is my settings:

Power Limit: 100 (Untouched)
Core clock: 1607 (+ 600) = 2207 MhZ
Memory clock: 8008 (+ 625) = 8633 MhZ

When doing this testing with FO4 at Ultra here is the specs of the testing: (Highest/Lowest)
GPU Usage: Min:0 Max: 68
GPU Temperature: Min: 32 Max: 41
Core Clock: Min: 253 Max: 1607
GPU Memory Clock: Min: 405 Max: 4007
Memory Usage: Min: 249 Max: 2600
CPU Usage: Min: 0 Max: 92
CPU Temperature: Min: 35 Max: 51


I am believing the low'ish FPS would be due to one of the following:
- High PhysX usage
- Godrays (even though my testing was during night gameplay)
- CPU Bottleneck

Thanks for your time to read this

Also, I am not a fanboy of ANY GPU maker, but have never owned a Nvidia GPU until now, as have in the past only been able to afford budget builds, so am not entirely familiar with using one

You've got a clear case of having a CPU bottleneck. Because of that, you aren't going to get very much from overclocking the GPU.

Just turned down the PhysX stuff, and it seems to be getting a decent 65+ FPS now
(The debris and godrays)

but this CPU isnt really much of a bottleneck?
What made you come to that conclusion?

Easy. Your CPU utilization is near 100%, while your GPU utilization is at 68%. If your CPU was able to keep up, your GPU utilization would be higher, and your performance would be higher.
