Nyt Posted November 11, 2020 Posted November 11, 2020 Very useful guide ! Especially the part about the CRC check on the memory which means a bad memory overclock will probably cause performance loss first instead of artifacting or crashing first like previous cards. The review mentions using the Unigine Heaven benchmark and I definitely found it very useful, especially for testing the memory overclock. When I was testing my memory overclock on Unigine Heaven benchmark at 2560x1440 with max settings this is what I found : Memory offset | Average FPS | Score +0 : 127.3 | 3206 +250 : 127.7 | 3216 +400 : 128.0 | 3225 +500 : 128.3 | 3231 +600 : 128.4 | 3236 +700 : 128.6 | 3240 +800 : 128.8 | 3244 +900 : 128.9 | 3248 +1000 : 129.1 | 3253 +1250 : 129.6 | 3264 +1499 : 116.7 | 2940 +1500 : 117.3 | 2955 The memory on my MSI RTX 3080 Gaming X Trio seems to be very good. All the way up to +1250 I still found gains in performance in Heaven. Only after that point did I experience the performance regression associated with the CRC check on the memory and it's quite a severe drop.

ir_cow Posted November 11, 2020 Posted November 11, 2020 Nice! The Trio I reviewed was able to reach +800, but after a few hours of benchmarks it started to crash the computer. So I settled on +400. You seem to have a very nice card. I know Micron has 21.5Gbps memory. Not sure NVIDIA didn't use it and stuck with 19Gbps. Maybe due to heat issues?
