If Your Timing Isn’t Great, Increase The Frequency Of Your Interruptions
DDR5 still has a bit of a timing problem, for instance the timings of 32-39-39-102-141 on the G.SKILL Trident Z5 DDR5-6400 do not impress, but that frequency certainly does. At double the frequency recommended for Threadripper and EPYC systems it makes one very curious what the performance would be like and makes one long for DDR5-7200.
That test will have to wait, as right now if you want to try DDR5 you will need an Intel system, one such as the Core i9-12900K TechPowerUp tested on both an ASUS ROG Maximus Z690 Hero and an ASUS TUF Z690 Gaming. The RAM topped the charts in many tests, breaking 100,000 MB/s read and almost 90,000 writes in AIDA.
That got even better when they overclocked the RAM, as well as when they tightened timings. You can see how that went right here.
