I have had a 13700K now for the past few years. Right when it came out, I got it. Fast forward a few years, cpu goes bad, i get the microcode update, get a new CPU and here we are. I built this system originally with an RTX 3080. For ram, I was thinking, why should I buy some more when I have a good kit from my 6700K. So I farmed that 4x8GB part to this new build (bad idea). Honestly gaming was good, but never great. I always had these stutters. No matter the game I played, the stutters were always there. Kind of got used to it, thinking it is what it is.
Fast forward I got a 5080. Bagged one for $1100, thinking this will resolve my issue for sure. FPS went up nicely, but guess what, stutters still fucking present. in-fact, now they are just MORE OBVIOUS.
I know the ram is the flipping culprit. Questioning if it is basically really worth considering upgrading the ram, or just say fuck this platform and move on when Ryzen 10 drops.
Did some research and with some guidance, I found a 2X 16GB DDR4 4000 (16-16-16-36) 1.4v on ebay for $250 shipped.
During this time of waiting, I start reading, watching videos, looking at the cheat sheet, just to have some understanding of what I am going to need to do.
Installed the ram, spent about 8-9 days of testing and tuning. This is what I ended up with. Ram Timings are in the Picture.

Ran Prime for 4 hours and no problems. Ran Anta777 Extreme for 7 Cycles and passed.
Max temp on the ram is a bit high, 46.2C for DIMM1 and 44.2 for DIMM3. I am getting the heat spreaders from AlphaCool and the gelid ultimate pads tomorrow to drop temps another 4-7C. If temps drop to 40C, I will max tREFI, is what I am thinking. Dropping system latency to about 43nS.
Overall Performance improvements
I didn't have much of a test bench. I only tested 2 titles and Cinebench R26. Plus my testing method was probably shit 😂.
I kept my same mVolt+ profile to try and make this as fair as possible. GPU is an RTX5080, which is scoring about 9850 on Steel Nomad for daily driver profile.

These test were performed on my system and these are the performance gains I have seen in games and in synthetic testing. I would say In the end, this was the most impactful upgrade of this build. There are no stutters. No matter the game I am playing now, they have completely disappeared. Frames are much more consistent, while max FPS did increase about 5%, My 1% lows shot through the roof. System responsiveness is on another level as well. This should definitely last me a couple more years. This just proves that memory sub-timing optimization is often more impactful than a raw CPU generational upgrade. Very happy with the improvements. It genuinely feels like I got a whole new Platform.
