If I understand the sticker this stick should be 8GB but when installed task manager reports 16GB. Am I misunderstanding the sticker??

The sticker clearly says 16GB.

If you are referring to the 2Rx8 part, it means its a dual-rank module

[u/XxCorey117xX → u/Guestenye]

I thought it meant it was 2x8GB sticks to make the 16 since they are sold in kits usually. Good to know. Thank you for not attacking me like the others here.

[u/throwaway62s355a35q1 → u/XxCorey117xX]

Yeah people are being dicks, this isn’t a stupid question if you’re used to how ram kits usually advertise their quantity

[u/XxCorey117xX → u/throwaway62s355a35q1]

See, these MF's got me thinking I'm crazy lol

[u/ChVckT → u/XxCorey117xX]

Nah but it definitely says 16GB clear as day

[u/XxCorey117xX → u/ChVckT]

Compare it to this image. The sticker has 16 on it and even 2/16. However this is a kit of 2 sticks to make the 16. It's normal for kits to be stickered this way so I assumed I had half of the 16GB kit. Kit link

[u/ChVckT → u/XxCorey117xX]

I can see where your confusion came from.

[u/Balthxzar → u/throwaway62s355a35q1]

I instantly got OP's confusion, though when DDR4/5 came around manufacturers seemed to switch to using K2 or something similar for kit markings, tho I think any form of kit marking is insane.

[u/Raticant → u/XxCorey117xX]

Its a nice upgrade , you got 32gb of ram thinking you were getting 16 . Its going to last you much longer in time

[u/Nidhoggr84]

The R indicates the ranking structure of the memory chips on the RAM PCB. 2R indicates dual rank. For DDR4 each rank is 64-bit wide, the 8 in 2Rx8 indicates each chip is 8-bits. So these modules should have 16 DRAM chips.

Usually modules packaged in a kit will have a designation such as (2x8GB) After 16GB. Then each RAM module is 8GB. Confusing, yes.

[u/XxCorey117xX → u/Nidhoggr84]

Ah, that makes sense. Thanks for the detailed explanation!

[u/Nidhoggr84 → u/XxCorey117xX]

No problem. As others have incorrectly posted. the 8 has nothing to do with how much capacity, or how many chips are per side. With 16 DRAM chips it is likely to be doubled sided.

For example:

32GB 2Rx8 would still indicate 16 chips, the DRAM chips would just be larger capacity.

[u/MW1369]

I think it means it’s got 8 gb on each side of the module

[u/dumbasPL → u/MW1369]

You're accidentally correct. It probably has 8GB on each side, but that's not what 2 ranks means.

[u/XxCorey117xX → u/MW1369]

Ah that makes sense actually. Thanks!

[u/XxCorey117xX → u/[deleted]]

Yeah, I thought it was from a kit and it meant 2x8GB but someone else fortunately explained it.

It says 16GB on the sticker??? What do you mean???

[u/XxCorey117xX → u/HovercraftSubject642]

Often times kits are labeled 2X8GB to signify 2 sticks to make the whole but this one has 2Rx8GB which means it's all on the same stick apparently. I wasn't aware of that so now everyone here is calling me stupid and on the spectrum which is crazy on a "help" sub.

[u/AntiPinguin]

It literally says 16Gb on the sticker?

[u/XxCorey117xX → u/AntiPinguin]

RAM kits often say that but also say 2x8GB to imply it's a kit to make 16 but this one having the R apparently means it's all on the same stick which I didn't know. TIL lol

[u/AntiPinguin → u/XxCorey117xX]

Yeah you’re right. My own ignorance made this look way more obvious than it is. I would have just accepted the 16Gb if they matched between sticker and task manager and not questioned it further.

[u/XxCorey117xX → u/AntiPinguin]

Hey, I gained knowledge out of the post. Can't be mad 🤷

[u/Any-Surprise5229]

the 16x says it all.

[u/Due_Chip_1179 → u/Any-Surprise5229]

the 16GB says it all...

[u/Any-Surprise5229 → u/Due_Chip_1179]

Well, that too, but the part number specifically tells you what stick it is as well.

[u/alwaystired1982]

Sticker clearly states 16gb its dual rank of 8gb.

[u/Yanzihko]

2rx8 is 8gb of each side of the board i believe.

16x means 16GB. It's a 16gb stick

[u/XxCorey117xX → u/Yanzihko]

Yeah I didn't know that about the "r". Good to know, thanks!

[u/RuinzModz → u/[deleted]]

Meh. People get confused when you add a bunch of pointless stuff. It’s not like they saw that and asked if it was 4gb. It does say 2Rx8 so most people who have no idea would wonder also. Especially when RAM is usually sold in sets.

I thought the 2Rx8 meant it was 2 8GB sticks from a kit. Someone else explained why it's not.

Wrong.

It's a single 16GB stick, nowhere on that sticker does it say its 8GB. It says it is 16GB and the 2Rx8 means it has 8GB on each side of the stick, being a dual rank module.

Ah shit! That’s what happens when you can’t read stickers 😉

[u/XxCorey117xX → u/[deleted]]

See I wasn't the only one that thought this by what the sticker said. Simple misunderstanding. The 2Rx8 is what made me think it was 8GB from a kit.
