Kingston Fury Beast DDR5-6000 2x32 CL30 ICs?

[frebro83]

Hello, I have been trying to figure out what ICs that are used for the Kingston Fury Beast DDR5-6000 CL30 memory kits and was wondering if anyone here knows.

FACTORY TIMING PARAMETERS
Default (JEDEC): DDR5-4800 CL40-39-39 @1.1V
EXPO Profile #0: DDR5-6000 CL30-36-36 @1.4V
EXPO Profile #1: DDR5-5600 CL40-40-40 @1.25V
XMP Profile #1: DDR5-6000 CL30-36-36 @1.4V
XMP Profile #2: DDR5-5600 CL40-40-40 @1.25V

They are on decent discount at the moment and I was thinking about buying them for a future AM5 build, but since I currently run AM4 I won't be able to test them to see if I like the performance or not until I buy all the parts and I got a bit scared after reading that (some?) of these do not even boot at EXPO settings and I was hoping to at least be able to run them at 6400 if I am lucky with the CPU silicon lottery.

The Kingston Fury Beast DDR5-6000 CL36 (not on discount) memory kits apparently runs Hynix A-die according to their EXPO self-assessment, but they did not publish this (yet?) for the CL30 kits.

Any ideas or suggestions?

Thanks in advance!

Someone who knows will answer about the IC, but does it matter knowing that information?

Those speeds should boot on any motherboard... I wouldnt worry about it.

All popular 16/32GB modules are Hynix A, and all 24/48GB modules are Hynix M. No other ICs can run at such low CL. If they suddenly changed ICs (but I haven't noticed that in tested kits), then it's still Hynix, as Samsung is not used anywhere. I also tested everything new from Micron, and they can't make CL30 at these settings.
Nearly all "gaming" memory kit series have Hynix IC, so it's not hard to figure out. Only some high CL kits, like some Corsair CL40+ kits, have Microns.
The worst overclocking Hynix kit I had still could make 7000+, but it was a dual-rank kit, so they OC worse.

Ah, ok. Thank you for the information, this puts my mind at ease. I was a bit worried that they would have switched to some cheaper IC.

As a followup, I noted that it is very hard to find 2x32 memory kits that are binned for high speeds (8000+). Is this something you have noted in all of your testing that the 32Gb modules are worse at clocking then 16Gb modules or is there some other reason why they are hard to find?

Dual-rank modules generally don't overclock past ~7600. You need some magical kit to do that. I mean 2x32GB, but also 2x48GB as they OC about the same. I could reach 8000 and run AIDA64, but that was all. I couldn't fully stabilize any kit at more than 7600. I may check it on Arrow Lake again when I find some free time. Recently, I was testing only single-rank kits for max clocks.
This is also why only 2 or 3 brands decided to sell dual-rank kits above 6400MT/s. The highest was probably V-Color at 7200MT/s, but it was quickly discontinued. I asked for a review sample just after release and it was already unavailable.

Ah ok, so that is what you mentioned above. Thank you.
