Could this be done with their M-die/24GBx2 kit? F5-6000J2636G24GX2-TZ5NR... Wondering how the timings would change for M-die...

2025-08-09 23:15:16 +0000 UTCCan I buy your kit?

2025-08-09 22:25:02 +0000 UTCno because verifying PBO stability especially curve optimizer is a massive time sink.

2025-05-08 09:49:18 +0000 UTCAre you doing any CPU overclock when running these timings, e.g. PBO? Or is everything else set to default in the BIOS? Thanks!

2025-05-08 09:41:05 +0000 UTCI can't verify 6600 1:1 because I don't have any CPUs that can run it

2025-04-23 19:44:57 +0000 UTCHey bullzoid, do you got timings for hynix M die 2x24gb, at 1:1 6600? I can easily do 6400 but im not sure what timings to use for 6600. thanks!

2025-04-23 17:34:07 +0000 UTCThe name of the die is just how manufacturers internally refer to their internal product lines. Since these aren't average people, they're just letters (or in some cases, I think, numbers). The dies used in the kind of DDR5 performance users, gamers, and overclockers are interested in, from SK Hynix, are A and M. Micron doesn't yet have anything we're super interested in, but their new inexpensive 24gbit chips are I think either B or C, and Samsung has absolutely nothing we're interested in, and they're at least at B now.

2025-03-11 13:50:57 +0000 UTCGot these timings to work. I just can’t get the PHYRDLs to match, any tips?

2025-03-01 14:28:03 +0000 UTCAlways love your detailed content! One thing I don't think I've heard yet is a definition of "A die" vs. "B die" vs. ??? You mention that as sort of a defining feature or something to look for, but I haven't grokked (not the AI product!) the meaning yet...
