WHY ARE YOU ASKING SO MANY QUESTIONS.
Oh wait, it was me that made the title to this post. Okay. Uh. Yeah.
So I am still alive and things are going OK, but to the 1 (maybe 2 tops) readers of my blog; yes, I have been slow to actually create new posts (or content). That is mostly because I am battling ADHD to make some really cool stuff happen in Blender. I have more or less been doing that non-stop. There is a national shortage of ADHD medication in the UK, so I am trying to get as much done as possible before my supply runs out.
As for my PC, well, I have an RTX 4090, not sure if I posted that already, but I've been through several parts. I had a 5800X3D for a while (sold it now) which was cool to test, but have now eventually settled on a 5900X that I got on an insane Amazon Prime Day Deal for £244. Since I missed my 5950X so much. Well, the 12-core seems more balanced on AM4, since memory bandwidth was an issue for me on the 5950X in some workloads (Eyesight render denoise, negative SMT scaling, RIP).
I also got some new RAM for it, probably the fastest Samsung B-Die bin DDR4 on the market (4400 19-19-19-39) and have two of those kits (2x8, so 4x8) running in 2DPC mode at 4333 18-18-18-38, 400 tRFC, GDM off, Cmd Rate 2T (go figure). Which is kinda nice for 4 DIMMS. Of course it's de-sync, so the UCLK is at 1083~ MHz and I am running the FCLK at 1867 MHz, the highest this 5900X will do.
I've done tests and the performance is better than Synced 3733 C14-14-14-31. Latency isn't that much worse either, because the memory is so high clocked. Bandwidth for days! Well, not DDR5 level, but it's reasonable for DDR4. I get about 65 GB/s copy in synthetic, which is mice. (63ns latency, if you're curious, in AIDA, which is actually good for desync Ryzen).
Anyway I'm typing too much already and there's like, 6 doughnuts in front of me, asking to be eaten. So yeah. Maybe I will have a post on some tests later, comparing memory performance on the 5900X and some scenarious where De-sync 4+ GT/s memory actually helps over synced <4 GTs memory.
Maybe.
Later!
