Asgard’s Aesir DDR5 is really quick out of the box, but we always like to see if we can squeeze a little more out of it. This is a baseline run for comparison.
We were able to jump right to 5000Mhz without doing anything. Our motherboard auto-adjusts timings to compensate.
5200MHz is also a breeze to achieve.
5400Mhz requires us to up the voltage to 1.2V but we clear the 80GB/s mark and latency is still slowly falling.
We were able to top out at 5600Mhz, but this required 1.32V to achieve
Our next direction is to reset to stock and see if we can tighten up the timings. Moving to C38 doesn’t require any effort on our part.
C36 also comes and goes easily.
We were ultimately able to get down to C34 but this requires 1.22V to get stable. It refused to go any lower and would fail to POST.
With some tweaking, we were able to get 4800MHz C36-36-36-75 at stock voltage which gets us a modest boost in bandwidth and much lower timings. Interestingly, we noticed this also affects the CPU’s L3 cache latency. Tighter ram timings seem to lower the L3 cache latency as well.
