Gtx 1060 bottleneck?

[Ruprekt79]

Hi All,

Wondered if I could get any advice on the following please.

I bought my son a G1 GTX 1060 for Christmas to go with his i7 930 CPU and 8GB DDR3 RAM.

I currently have a GTX 970 Strix and an i5 3470 with 8GB DDR3 RAM.

Neither mine or my sons components are overclocked.

We both play a lot of Forza Horizon 3 and my system runs the game at a much higher average FPS than my sons when using the same graphics settings (the only difference being he runs at 900p and I run at 1080p). I get 60fps pretty much constant apart from Surfers Paradise, but he gets around 30-40fps average even when in less demanding areas of the map. I will be trying his PC on a 1080p screen when I get chance but I cannot imagine the resolution is at fault?

As you know, his 1060 6GB is more powerful then my 970, so could it be his CPU that is causing a bottleneck on this game? If the i7 930 that much less powerful than my i5 3470?

Any advice would be really appreciated.

Forgot to mention that we both use HDD's not SSD's and both have the same PSU and are running up to date GPU drivers....

The CPU is causing the bottleneck for sure, especially since your sons pc is not overclocked and you have a newer one. The fact he is at 900p will also emphasize this further (lower res are more cpu dependent).

You could probably over come some of the problem by overclocking the 930 (if possible on the mb) about 4.2 should be fairly easily achieved with that cpu I believe, but of course the higher the better.

Thanks.

I am used to overclocking GPU's but not CPU's so will look into how to do that. I will first check his mobo and see if it allows an OC. His CPU is an after market water cooled one so that should be fine with an overclock.

I will report back but any more help would be appreciated.

There are two basic methods;

Overclock the bus, 100 or 133 whichever it is up to closer to 200 if possible. This also affects the memory frequency so a lower memory multiplier should be used.

Overclock by raising the multiplyer, jumps up in steps of half the bus frequency but does not affect memory speed.

You can of course do both. You probably need to raise the voltages a touch to allow for a higher frequency.

This will probably need an aftermarket cooler to cope with the increased heat.
