Here is an small update of this patriot cl19 b-die kit.

Already done these A2s are no joke

It's really interesting to see how tRFC behaves in the presence of an iGPU. I can pass endless TM5 runs @ 133ns without moving VDIMM even an inch, but the GPU really doesn't like it. 130ns no POST. 133ns tests stable but crashes instantly opening a game. 135ns test stable, runs for a while until throwing a UNEXPECTED_KERNEL_MODE_TRAP. 138ns (290) works just fine though.

It was the same with the A0s, tRFC went all the way down to 140ns stable but only about 143-145ns was actually iGPU stable.

On the A0s I couldn't do tRRDL 4, tWTRL 8 or tWR 10 without needing more VDIMM, not yet sure if it's the same here. I'll probably play with tRTP next.

@FilipM that reminds me, the old GDM vs 2T debate seems to be rather interesting. 2T is *sometimes* faster in membench by half a second or so. But GDM consistently wins in AIDA read/write by about 500MB/s and copy by about 200MB/s. GDM might also be leading to better GPU performance, but I'll need to bench that.

Unfortunately it's going to be hard to bench Genshin until I can set up RTSS properly, but in the meantime Valley works well.

So yeah, mostly placebo in gaming but definitely faster than the A0s at 4200 17-18-18:

If I remember correctly gdm makes tCL, tCWL, tWR and tRTP even values. If one of them is odd then 2T would probably give better performance.

That write speed i get is normal? This on an Asus X570 TUF

Yes, single chiplets like 5600X and 5800X get half speed vs 2 chiplets. Test dram calc to tweak your scores. 10ns lower latency with just ramtuning and a bit more speed should work

Sometimes tWR 10 and tRTP 5 works, that gave me a slight boost without requiring more voltage. tRRDL 6 and tWTRL 10 or 8 might work aswell

Unfortunately anything below 4/6/16 - 4/12/12 requires more VDIMM to stabilize, and it's looking like 0.02V or more at 4/4/16 - 4/8/10. 4/4/16 - 4/8/10, 4/6/16 - 4/8/10, 4/4/16 - 4/10/10, it's all the same: needs more VDIMM. It was a difference of like 300MB/s copy perf, no latency or membench improvement.

I know a lot of ppl run 4/4/16 - 4/8/10 and I remember BZ saying in a more recent video that the tighter timings shouldn't need extra voltage, but I suppose that's not the case.

My A0 B-die, 4Gb E-die and CJR also can't tighten past 4/6/16 - 4/12/12 without more voltage. Was hoping the better B-die could buck that trend somehow, but oh well.

Okay, tried 12/6 or 10/5 tWR/tRTP? Those timings affect perf more.
