I've decided to upgrade my PC and have been researching deals on DDR5 RAM.
I ordered this ram this afternoon at $149.67 then noticed tonight it had dropped to $134.70 so cancelled and re-ordered.
Couldn't see any recent deals on this variant or anything close at this price so sharing GLHV.
CamelCamelCamel.
I’m not even going to bother upgrading until I can get a current gen itx board for sub 100, I mean how hard can it be let’s see who blinks first
Same, no mobo. tempting to buy ram for new build in 6mth though.
Are their AMD/Intel models both using the same hardware just with different stock timings or is it a different die?
If I put the Intel optimised ones from this deal in an AMD build would I have to manually tweak something in the BIOS to get them to run at their rated speed?

Could be either or both - Corsair has entered the DDR5 part swapping era

Most AMD boards support XMP so the kits should run OK
But if you are really after plug and play, best to buy an EXPO kit which the vendor has specifically tested on AMD boards plus submitted for QVL on various AMD boards
If you are not fussed about specific dies and timings, price is decent
But be warned that Corsair has gone back to the dodgy DDR4 days of part swapping like mad on these Vengeance kits
Amazon lists CMK32GX5M2E6200C36 which leads to 6200MT/s Rev E with CL40-40-40-77 timings
Newegg lists the same P/N with CL36-46-46-100
The 6200MT/s non-Rev E CMK32GX5M2B6200C36 is listed as CL40-40-40-77 on Corsair's site but CL36-39-39-76 on Newegg
If you are building for AMD, better off getting the Hynix-M Team T-Force Vulcan Alpha 6000/CL38 kit
Which die would this Corsair 32gb 6200MHz DDR5 ram be? I couldn't find anything specific online but I'd assume Hynix M die?
I'm new to pc building. Mind elaborating on 'part swapping' part? How is this bad?

No one knows - you would have to buy and inspect it yourself
The fact that Amazon/Corsair and Newegg list different timings for the same PN means the die has been changed "sometime" so you cannot even be sure the Amazon stock is not a mix of old and new
How is this bad?
Certain dies like Hynix are preferred for better overclocking and compatibility
Certain vendors - like Corsair - like to release limited quantities of a kit with the good die so early reviewers and buyers recommend it
For the next production run, the same kit will be downgraded to a cheaper crappier die with worse timings and less overclocking ability
Some vendors might do a stealth part number change ("Rev E") whilst others will even keep the same part number
Thanks! Would this be a better buy for an Intel build? The G.Skill F5-6000J3238F16GX2-FX5. CL32, 6000MHz. It's only $20 more but from a more "trustworthy" brand. Would I see noticeable differences?
@boomersgold: If $20 extra is fine for you, get the G.Skill
That kit is Hynix-M die and has good feedback from other members

Just an update on this. I bought this RAM kit from Amazon. The packaging says 6200MT/s, 36-46-46-100, 1.40V ver 3.43.02. I'm almost certain it's a Micron die based on the version number starting with 3-. That's disappointing when all of the reviews for the 6200MT/s, 32GB Corsair Vengeance RAM said it was a Hynix die. Seems you were right about the parts swapping.
Would you suggest keeping this for an Intel build? At $134, it's still a decent deal. I might be able to find a G-Skill Hynix-M RAM kit for $10-$20 more on sale.
Noticed this when I was looking at kits earlier today. Weird stuff.
with CL40-40-40-77 timings
Looking at the specs tables on those corsair.com links you posted they show the SPD Latency.
| SPD Latency | 40-40-40-77 |
| SPD Speed | 4800MHz |
| SPD Voltage | 1.1V |
| Tested Speed | 6200 |
| Tested Voltage | 1.40V |
I guess if they leave out the Tested Latency they are then free to change the subtimings however they see fit as long as CL remains 36.
General dodgy behaviour from Corsair, nothing new
If you are fussed about RAM and do not want to support shit vendors, get G.Skill
Look at the specs page from this deal
First block of text, straight up detail and no ambiguity:
F5-6400J3648G24GX2-RS5K
Ripjaws S5
DDR5-6400 CL36-48-48-102 1.40V
48GB (2x24GB)
Intel XMP
If you are building for AMD, better off getting the Hynix-M Team T-Force Vulcan Alpha 6000/CL38 kit(pccasegear.com)
I'd agree with you prior to AGESA 1.0.0.7b, but you can actually get quite a bit over 6000Mhz with a 1:1 IFC ratio now, and poorly binned Micron Rev M timings are also not that great from what I've seen. My 5600Mhz C36 kit can't do above 6000Mhz without loosening primary timings a real lot. Can't imagine 6000Mhz C38 is much better. Most of the gains are still to be had in the tertiaries though regardless.
I would take listings with a grain of salt. They’re often inaccurate. Unless there’s a review specifically listing diff specs from the same part number, and even happens on manufacturers websites. But the CL is usually listed in the part number and that should be the real value.
Price is $180 now
So, for someone who hasn't actually built a DDR5 system, is there an equivalent of Samsung B.Die RAM? The last rig I built, I used a set of G.Skill F4-3600C14D-32GTZN DDR4 B.Die chips and has been great but yeah, just trying to figure out the "optimal" DDR5 chips to get/use.
There is, the current best RAM would be Hynix A die or Hynix M die. Typically 6000mhz kits running at CL30/CL32 will have a Hynix die. Main benefits of Hynix is that they can run much more stable with tighter timings.
I have 4 DIMMs (all CL32 6400 MHz) from previous deals, two of them are M-Die (48 GB each), others 2 (32 GB each) just shows as Hynix so don't know which die.
For this generation, you'll be looking at Hynix A-die being the best/preferred and followed by Hynix M-die which is also preferred and more prevalent. If you're building an AMD system, it doesn't matter A-die or M-die because its sweet spot is at 6000MHz, CL30. With A-die there is a possibility where you can tighten the timings even more. If you're on Intel platform, A-die is preferred because you can run this at higher frequency and with good timings as well.
Thanks both @fluffchuck & @Davesday! Both very good explanations. I'll have to keep that in mind. I tend to build mostly Intel based systems. Any particular 32GB kit(s) you can recommend in my case?
I'm not too familiar with the exact kits that you would want for Intel, but I do know that a low CL (CL30 or CL32) with a high speed (6000mhz+) is ideal. G.Skill is really good, either their Ripjaws lineup or their Trident Z5 lineup. Try to avoid anything that is CL36 (unless its like 7000mhz+) as it is unlikely that it'll have a Hynix die
Ahhh champion! Thanks @fluffchuck, I'll do some digging. Much appreciated mate :).
So cheap, too bad I don't have a DDR5 board.
