Overclocking

For my last bit of testing I wanted to see how much I could push the 380X Strix with its stock cooling. To do that I break the testing down into three sections. I overclock the GPU first and find the highest possible GPU overclock on a stock setup. Then I do the same with the memory clock speed. Then I put both together and see if they will run together. Starting on the GPU Clock I ran the stock clock then jumped immediately up to 1200 MHz to see if the card could handle it. I picked 1200MHz because that was about where I was able to overclock with the R9 380. This failed, but as I stepped back to 1100 MHz I got a passing result. From there I just had to work to pinpoint how far I could go. Sadly, I wasn’t able to get past 1110 MHz. I did see a 4 FPS jump in performance though.

Going off of the R9 380 that is based on the same Tenda GPU as the 380X I expected my memory testing to go very quickly as the 380 maxed out the software. I jumped through a few tests quickly but the 7000 MHz test failed. More testing found that the 6500 MHz test I ran was the highest memory clock I was able to reach. This only gave me about .4 of an FPS over the stock tests. The lack of a result and the high risk that memory overclocking has means this isn’t really worth it at all. I did still run my combined testing though and had no issues. Combining the overclocked memory into the overclocked GPU gave me a total of 66.74 FPS in the final test.
