Hi all,

I have a Strix X99 Gaming Motherboard, an Intel i7-6800K and a Gigabyte RTX2080 Super with 32gb DDR4 Ram. I just did a completely fresh installation of Windows 10 Pro on a Samsung EVO 1tb SSD.

My issue is that this configuration does not seem to be scoring very well in 3D Mark. Here are my results:

For comparison, here is a result from someone else with the same CPU and a standard RTX 2080 which as you can see, scores much higher than mine:

I'm a little perplexed as to why I'd be scoring lower with a superior graphics card. As mentioned, this is a completely new installation of Windows 10 literally just completed in the last hour or so. Fresh drivers from the nVidia website.

Appreciate any help.
Zach

Just to confirm before you purchase a new kit of memory. Do you have those two memory modules installed into the proper dim slots on the motherboard? According to the manual it states to use dims B1 & D1 (if you have two memory modules). It is possible having one of those modules misplaced in an incorrect dim slot may negatively impact performance.

Refer to page 1-5 of your motherboard's manual:

If this is the case, you may see a significant performance increase without the need to spend $100-200 on a new memory kit.

Just to confirm before you purchase a new kit of memory. Do you have those two memory modules installed into the proper dim slots on the motherboard? According to the manual it states to use dims B1 & D1 if you have two memory modules. Having one of those modules misplaced in a incorrect dim slot could potential run your system in single channel mode, let alone running it's full potential capabilities of quad channel.

Refer to page 1-5 of your motherboard's manual:

I believe they are in the correct slots. Is there any easy way to check I'm running in Dual Channel mode without having to open up the case again and physically check my slots? Can CPU-Z tell me?
 
Yes, it can. If you look on the memory tab next to Channels#.

Even so, 2400mhz is very slow for that platform. I would expect the difference in speed AND quad channel operation, to be at least moderate when combined. Probably well worth doing. System will likely "feel" much snappier.

OK I have confirmed it says Dual Channel.

I didn't know that I'd have to re-do my settings after the new RAM arrives. Thats fair enough and I'll stop messing around any further now. That being said, I did push my GPU overclock to 4%. 5% caused it to crash out.

Interesting thing though:

https://www.3dmark.com/spy/9067176 (GPU OC 3%)
https://www.3dmark.com/spy/9067510 (GPU OC 4%)

For some reason, my CPU score dropped by almost 450 points in this run. My graphics card score increased as expected. Could there be something wrong with my CPU causing the performance to vary?

Following up. I figured out two things:

  1. My motherboard had my RAM clocked at 2132mhz in my latest tests. Don't ask me why. I bumped it up to what it should be, 2400mhz which is where it was in my first test.
  2. Left my GPU OC at 4% and increased my CPU from 4000mhz to 4100mhz. I initially tried 4200mhz but it blue screened during the last 3D Mark test which stresses the CPU.
https://www.3dmark.com/spy/9068468 < am now at 10124 score which I consider reasonable without the RAM upgrade.

Its gonna take a few days for the new RAM to turn up, so I'll follow up here once I have the new RAM installed and tested.
