Crucial 32gb (2x16gb) cl16 3600 BL2K16G36C16U4B - Single Rank

My ram is dated 2043. I haven't had it in a machine yet to check it but looking at it it only has ram chips one side of the PCB, leading me to think it's single rank.

the new single rank must be really recent stuff like last 3-4 weeks manufacturing unless they started to be mixing it up.

mine is week 39 2020 which is end of september

Its a complete mixture, anything from July 2020 onwards can be either Rev E dual ranked or Rev B single ranked. You need to look in either CPUz's Part Number / Rank field on the SPD tab or on the label stuck on the memory itself to find out (if unopened the Part number may be on the label on the outside of the box too, it used to be but I haven't bought crucial memory since DDR3 so I cant say for certain). If the Part number ends in .x16xx its 16 chips and dual ranked, if it ends in .x8x its 8 chips and single ranked. The important part is the number in the section after the dot, not the letters - these can and do change. This applies to Crucial memory only, not other brands using micron chips.

Correct...single sided = single rank :)

Any other alternatives to crucial for 3600mhz c16 32gb dual ranked sticks?

Crucial make the best ones for clocking. There are some Samsung and Hynix sticks but they have very little headroom in them and cost around the same. Just stick to Crucial for 32gb sticks.

Thanks. Just have to now wait for stock to reappear. I contacted crucial a few weeks back but they didn't know when new stock would be back in.

Is your signature up to date? The X99 bioses are definitely not well optimised for 32gb sticks of any type. I have an R5E, MSi Godlike and a GB X99 SOC and none of them do well with 32gb sticks even dropping down to triple or dual channel. I would be especially cautious over Micron Rev B as its less than a year old. Zero chance of ever getting bios optimisation for it on the X99 platform.

The memory is a for an upgrade. I have a 5900X ordered and will be picking up a X570 Asus Dark Hero when it is released.
 
Guys, I ordered a white 32GB set (2x16GB) in mid October and they are still sitting sealed in the box.

I've taken a look at the labels on each of the two sticks and can see the following: 2033 BL16G36C16U4WL.M16FE1

I know next to nothing about ram but if I've understood the thread information correctly, I have the good to use version?

This means there are 16 1gb ram chips on the PCB so it will be dual rank. Not as good as single rank as it will put more load on the memory controller if using Ryzen. Not really an issue if you are only using the two sticks and I don't know how much of a performance hit it would take if using four sticks together, maybe someone else can chime in.

Thank you. I'm only intending to use two slots on the MB so hopefully I haven't made a bad buying decision :)

I think you've received some fluffy answers here from others!

If you only intend having 32gb, then yes, you have the best memory. With only 2 sticks, dual rank will give better performance than single rank sticks. You might have an issue if you put more memory in your system (ie 64gb), but it sounds like this is unlikely.

OK, thanks Stu. I've struggled to take in the heavier technical descriptions in the videos I've seen and got myself a little lost to be honest. All the channel and rank stuff goes way over my old head! The main thing I noticed were higher scores when using 4 sticks of the same memory over 2 and I drew my conclusion from that.

I guess I'll be OK if I stick with what I have now and be mindful that I could introduce strain on the memory controller if I ever try to add another two 16GB sticks, which I'm unlikely to do.

Thank you to everyone who came back to me with answers and guidance :)

This has been a hot topic lately! The easiest way to explain, in most cases, you get best performance with 4 ranks of chips... This can be achieved with 4 sticks of single rank (4 X 1 = 4) or 2 sticks of dual rank (2 X 2 = 4).

4 ranks gives better performance than 2 ranks because you have more bandwidth due to the additional ranks.

You might ask, why not go higher than 4 for even more bandwidth? In many systems going above 4 ranks puts more strain on the memory controller... It will still work but you must use slower timings and/or speed, thereby losing performance.

That's a great explanation. I can take that in and understand it so thank you very much for taking the time to lay it out like that for me. Now I get it!
 
I feel quite lucky now. I bought a set of these on a bit of a punt as the price seemed notably lower than anything else with similar speeds. I did a little research which is how I got to 3600 CL16 as being my target. Bought these over a month ago and still have probably another month to wait for my 5600X.

After doing more research I realised I should have checked about the single/dual rank situation but luckily I can see my kit is M16FE1 so should be good!
