Have completed my initial minimum VDD requirement for 6400MT/s CL26 testing on about half of my memory, so will share my preliminary results as promisted
The following memory sticks have put to the test:
Trident Z5 Neo RGB DDR5-6000 CL26-36-36-96 1.40V @
custom heatsinks (new generation PCB*)
Trident Z5 Royal Neo DDR5-8000 CL38-48-48-128 1.45V @
custom heatsinks
Trident Z5 Neo RGB DDR5-8000 CL38-48-48-128 1.45V
Lexar ares gen2 6000 CL26 @ 1.45v (new generation PCB)
My interest was mainly to discover how tightly these sets were binned, and if there was a large difference between the SKUs
I picked the 6400MT/s memory speed at tightish timings since i view this a middle of the road approach which all A-die should be able to run, and other overclockers also can use this as a comparison for their sticks if they wish to. Please note tCL is the main timing that can be forced with VDD, and will also be the limiting factor when voltage limited/constrained. Stress-test of choice was karhu which i started when i went to bed for the night or work in the morning, so target runtime was around 6-9 hours.
Should also be said that i'm fully aware this is only a sample size of 1 per SKU, so it dont mean too much, but i have to work with what i have
Half of the memory have been run on the ASUS APEX while for the other half on my livingroom media-computer running a ASUS GENE+2233FCK 9800X3D sample .
But at this lowish memoryspeed motherboard should not really matter, as long as the cpu is is capable and the motherboard is not total junk.
(and 3 different cpus were used for this, but the only metric i'm looking at here is VDD+stability at given mem settings)
That's enough talking, over to some data
My new G.SKILL 6000 CL26 seems to be out of this world and managed to run these settings at only
1.47 VDD which i have to say i find really impressiv, these new sticks really are the next generation.
Next up we have the Royal Neo 8000 CL38 which used to be my "primary memory" before. It needed
1.590 VDD to keep stability
My regular Trident 8000 CL38 fared the worst of the bunch and needed
1.64 VDD
And lastly we have the Lexar 6000 CL26 which also did pretty good, coming in at
1.56 VDD.
One strange thing about this printer memory is that it absolutely hate to run 2:1 mode on the GENE/ASUS, even at very slow timings and 8000MT/s speeds, which all the other memory kits above ran with ease. System was acting totally loco and was very unstable with the lexar memory installed running 2:1 mode while in 1:1 mode it was totally fine.
When Chew was active he found kinda the same, Lexar was a good match with a Gigabyte Tachyon motherboard and a bad match for ASUS GENE motherboard. No idea what's the cause of this, only rreporting my experience ..
So can only recommed this memory if you plan to run 1:1 mode on ASUS motherboard, good thing is that is pretty cheap compared to the rest.
Following memory kits waiting to get added to the comparison:
2 different sets of G.SKILL 6400 CL30
1 set G.SKILL 6000 CL26
dual rank (working on it as we speak)
1 old set of G.SKILL 6400 CL32
dual rank
And i might throw in some kleev 7600, teamgroup UD5 7800 and T-FORCE XTREEM 8000 depending on the interest (y)

invictus for taking nice photos, first thing i did was drown mine in painthinner and installing the new heatspreaders, without taking any pictures)
