Cheaper, faster stock speed and better Hynix M-die than the last 64GB deal
Usual minimum overclock is 6000Mhz CL36 @ 1.35V

This ones $25 more but CL36 and comes with RGB.. Do you think its Hynix M-die as well?

Likely Samsung B-die
So even though it has a lower CL its not as good?.. Looking at maybe using it with AMD 7600 or 7500F
It's fine just not as good for overclocking
@vid_ghost: Not true. I have a 7600x and it can do 6000mhz @CL28 @1.36v memory @1.08v SOC with my Vulcan Z 32GB 5600mhz cl36 M-die kit which keeps latency at 57.2ns compared to stock 80ns. The point of am5 is also to get future CPUs released on the platform which will have even better IMCs so get a cheap A die kit if possible (T-create 32GB was on sale for $148.95 a few months ago). The maximum in gear 2 I could reach is 8000mhz CL34 but this incurs additional latency so the motherboards themselves can definitely support high speed modules.
Check netsurfer's AMD experience
For this gen of DDR5 dies, Hynix is rated higher than Samsung so if it is $25 cheaper, you would take it every time
Check to see if that memory kit is in your motherboard's QVL. You can drop the last letter (W) which appears to be the colour. For example, that kit you posted is not in my motherboard's QVL. My experience with Samsung ones not in my MB QVL was quite unpleasant. I agree with chatGPT that based on the product SKU, it appears to be Samsung.
The good thing about buying from Amazon AU is that it has good return policy. For DDR5-5600, you'd want memory context restore to work properly on the AM5, otherwise every boot will require a memory retrain. I found re-training DDR5-5200 every time is quite fast, but anything above DDR5-5400 takes quite some time and gets annoying.
Noon question. Is ddr 5 over ddr 4 worth it when gaming? I see the higher clock but the timings are massive too. My current ddr4 is 3600cl14
Hardware unboxed did a video on it showing an improvement with DDR5
Currently not so much. DDR5 is quite new so the technology isn't as mature and speeds aren't as high as we can get yet. Absolute latency is what the cas timings and transfer speeds contribute to, measured by:
Cas Latency * 2000 / Data Rate, so:
For your ram:
CL 14 at a transfer rate of 3600 MT/s translates to 7.7 ns absolute latency
For this deal (usual minimum overclock):
CL 36 at a transfer rate of 6000 MT/s translates to 12 ns absolute latency
Latency is only one factor in memory performance but generally DDR5 is better for some applications. As this technology gets more mature, it will definitely be better than DDR4 in the future for all applications.
For now, performance benefits depend on how latency vs bandwidth sensitive your use case is. If your use case primarily requires low latency (e.g. many small transfers, such as gaming) DDR5 might provide no benefit at all (at least for now). If it is bandwidth sensitive (e.g. few large transfers, such as video editing and rendering) the much higher transfer rate is going to benefit you.
Thankyou for the thoughtful response!
I think you should tune your (b-die) ram before upgrading to DDR5
It depends on the games, some games benefit more from lower latency, some games can take advantage of higher bandwidth. In the long run, DDR5 will be better. However, GPU is still far more important than system RAM.
How do we tell whether these are hynix m-dies? Ultimately you would have to receive the kit and look at the serial number for some kind of an indication, right?
Generally, the current approach before purchasing is look at various motherboard's memory QVL list. Ideally, look at the one for your motherboard.
Based on a number of memory QVL, this one appears to be Hynix M-die kit.
Ah that's fair.
SOLD out.. i didn't end up getting one.. i guess i'll wait until next year and see how mature DDR5 is when Ryzen 8000 releases
The latest AM5 AGESA still hasn't fixed Samsung die compatibility issue fully. The DDR5 experience so far for me is worse than DDR4, especially when using an incompatible kit. After turning off PC, wait 30 minutes, next boot could just get you memory error.
Memory training for high speed DDR5 takes ages. For example, same Hynix M-die kit, DDR4-5200, about 10 seconds, DDR4-6000, 2 minutes. Every time you change the RAM frequency, it requires a memory re-train. This is something we don't experience with DDR4.
So your saying wait for DDR5 with AM5 to mature ? .. my PC is rock solid at the moment.. I would hate to have to deal with PC issues like that with DDR5
MSI B550 Mortar Ryzen 5700X @45w 32GB DDR4 3600 CL16, RX6800 16GB @135w. on a corsair RM650X probably the most stable, low power and coolest running PC I've ever had.. Boot & load times next to nothing with 2x 1TB 980 Pro's
I am guessing your current setup uses Micron E-die RAM modules. I also find the Ryzen 5xxx series, B550 setup quite stable and pain free (most B550 boards are released after X570 and board makers did make some minor adjustments to make memory work even better). B550 boots fast.
DDR5 with AM5, I don't think I can offer an objective view with just trying out 2 memory kits. The Samsung DDR5-5200 kit I tried is not in the QVL of my motherboard. The SK Hynix M die kit DDR5-6000 is in the QVL. Without memory context restore, AM5 with DDR5-6000 is a real pain (2 minutes to do memory training for every boot is just not something you want from the latest and greatest). With memory context restore working, my boot is faster than my B550 setup. With AM5, when everything works properly, it is quite good. Problem is, when it doesn't and it is memory related, it is a real pain. My motherboard doesn't have the nice diagnostic code thing, only 4 LED status lights. It was not useful when both CPU and memory LED status light wouldn't go off when troubleshooting. I found the PC speaker (4 pin) much more useful. 3 beeps, memory problem.
The memory re-training part of DDR5 is still annoying. My DDR5-6000 kit has 2 profiles, DDR5-6000 and DDR5-5800. Problem is, every switch requires a memory re-train. DDR4 doesn't have that issue (or the DDR4 frequency range is much lower so the training is very fast).
