I recently had the chance to get a Micron DDR 5 Kit ( CP2K16G60C36U5B.M8D3 – 2x 16GB DDR5 36-38-38-80 ) for 250 Euros and I thought why not. While the Kit isnt the worst, it took me quite some time to figure out reasonable timings. I also have to say that I never changed any RAM Timings at all so im fairly new to this.
While I could achieve more aggressive Timings, I had to up the VSOC to regions I did not like. Im not really hunting for the best performance, but for a good mix in performance and stability.
After I settled the timings to a not too bad amount, i then decreased the voltages because I like to have low temps. VSOC is currently at 1.16 ( Asus Boards Report it Wrong ) and 1.2 VDDIO ( same stuff). I also tried Nitro 1/2/0 but I had crashes and reboots.
After 4 Hours of OCCT while stressing my RX 9070 XT to the max, my RAM did not exceed 45 degrees. I could bring AIDA Latency down to 63ns.
I did 8+ hours of Prime95, y-cruncher VT3, OCCT and AIDA and could not get a single error. Stability seems good so far.
Since there are literally about zero guides about any Micron DDR5 Die, i used Buildzoids Guides and the Foolproof DDR5 OC Guide. While im happy with stability, I would know if anyone has any advice on further improvements. I already tried to bring down tRAS and tRC further but I did not gave me any latency or performance increase. I tried to bring tRFC down below 800 but it didnt boot.
Maybe this will also help other people with this Kit. As I said, in completly new to RAM OC, so any help is appreciated.
Cheers!
