German Engineered Perfection: der8auer Overclocks the EPYC CPU!
der8auer Overclocks the AMD Ryzen EPYC and Simulated the Ryzen Threadripper 2990X
In order to simulate the AMD Ryzen Threadripper 2990X, Roman used an article from wccftech.com (external link) and picked out the presumed clock frequencies of the 32-core HEDT processor. According to wccftech, the Ryzen Threadripper should clock at 3,4 GHz and Roman overclocked the EPYC 7601 server processor to just this clock rate.
The test system looks as follows:
- AMD EPYC 7601, 32 Cores, 64 Threads
- Supermicro H11SSL-I server motherboard
- 16x 8 GB registered 2.666 MHz RAM sponsored by Crucial!
- Seasonic 850 Prime Platinum
- EVGA GeForce GTX 1080 FTW
- XSPC Raystorm CPU cooler
- Water chiller
The Benchmark Results from the Overclocked EPYC 7601
The AMD EPYC 7601 was overclocked to 3,4 GHz with four sticks of RAM operating in Quad-Channel mode and achieved a Cinebench score 3.867 points. Should the AMD Ryzen Threadripper 2900X also clock at around 3,4 GHz on all cores, these performance results should give a rough guide as to the abilities of the new processor. However, it should be noted that the Epyc 7601 does not support higher clock rates in memory. Benchmarks with a Ryzen Threadripper 2990X and overclocking memory would probably fail. Further benchmarks with this plus eight memory modules courtesy of Crucial were able to achieve an incredible score of up to 5.227 in Cinebench. Subsequently, for AIDA64, Roman took a look at the RAM timings to enable him to maximise the possible throughput and minimise latency, in spite of how much RAM was in use.
For the AIDA64 benchmarks, the EPYC was overclocked to 3,8 GHz on all 32 cores (!). First, four RAM modules were tested in Quad-Channel mode and the following values were obtained:
- Read: 65 GB/s
- Write: 63 GB/s
- Copy: 62 GB/s
These already good results were significantly improved and almost doubled with the use of eight modules:
- Read: 123 GB/s
- Write: 125 GB/s
- Copy: 117 GB/s
