Laptop Memory Upgrade

[Lurx0720]

I want to upgrade my laptop RAM from 16 GB to 32 GB. I have an Intel i7 11800H and I don’t know what latency is best for it. The only 3200 Mts kits I saw were CL20 or higher and the only CL16 I saw were 2400 Mts. And I saw the video that x8 and x16 density matters. Does anybody know what memory kit is 3200 Mts CL16 x8 density?

3200 CL16 kits of laptop memory do exist, I know G.Skill has one and I'm pretty sure Corsair, Kingston, and a couple others do as well. The problem is those kits are XMP rated, and the vast majority of laptops don't support XMP, meaning that even though the kit is capable of running 3200 CL16, practically you'll be limited to something like 2400 CL15 or 2666 CL16 when using those kits unless you have one of the few machines that support XMP. 

 

Your best bet will be to stick to a JEDEC official speed bin rather than trying to use an XMP kit. 3200 CL22 is the fastest JEDEC approved speed bin I'm aware of, so it should be what you target. If you care about the organization (what the x8 and x16 refer to), know that 16GB sticks of DDR4 are guaranteed to be either 1Rx8 or 2Rx8, so you won't have to worry about getting 1Rx16 based kits. If you do still want the faster of the two, the 2Rx8 kits will be faster, but they're double sided so laptop compatibility is a little more complicated. Unfortunately, unless you find a listing that has the exact organization listed, you'll have no idea what it will be. Most OEM sticks will list that though, so I'd be looking at kits primarily from Crucial, Micron, Klevv, Samsung, and SK Hynix if you want to worry about the ~5-10% faster memory performance depending on the workload you'll get with 2Rx8 based kits, or just getting the cheapest 3200 CL22 kit you can find if you don't.

Abit offtopic but if its 3200c22 jedec then default speed without xmp is 3200?

 

If so i wonder if thaiphoon can edit spd to tighten up the subs or even increase dedault ram speed without xmp, never really considered laptops that much but now im kinda interested considering most laptop ram is kinda slow with the horrifically unoptimized subs and primaries

Kingston let you pick what configuration their laptop ram is. Link is to their UK store but I'm sure you can find your regional equivalent: https://www.kingston.com/unitedkingdom/en/memory/client/ddr4-3200mts-non_ecc-unbuffered-sodimm

3200C22 2Rx8 is probably best general performing in standard modules. I have seen some non-XMP 3200C20 before but they were 1Rx8 so would likely perform worse in most cases.

The module SPD will list all the standard speeds it support, up to 3200. If the host system supports 3200, it will run at 3200.

Thanks for the answer. I tried to configure some memory by my liking an dI have one more question. What is better 16GBit density and 1R rating or 8Gbit density and 2R rating?

Can thaiphoon program spd faster than 3200? Thats what im mainly curious about since theres very few laptops that let you enable xmp, if not then tightening the subs will suffice

The lower density is what allows the extra chips to be added giving the 2nd rank per module. Personally I would go for 2Rx8.

I have no idea if Thaiphoon Burner works especially on laptops which can have funny or more restricted access to hardware. The danger I feel here is that even if you pay for the full version and can update the SPD, you could put the module in a state where it isn't working, and you can't just reset bios and undo it. It is also unclear to me how systems will react to non-standard SPD profiles. 3200C20 is still a standard profile, but to go below that it is non-standard. It is questionable if these systems can deliver increased voltage if set in SPD, which is usually required to tighten timings. IMO this is not a battle worth fighting. It's a lot of effort, cost and risk for a gain you'll probably not notice outside of some benchmarks.

Im more interested in the buisness side of things here as per usual cause boy that mobo is taking a while to get here and its been days, also just diversification

 

Im not talking using a laptop to actually modify these sticks ofc not, im looking at buying those sodimm adapters that can adapt sodimm to a normal desktop slot so i can tune the rams in bios and when the desired settings work use thaiphoon to program then test in a laptop

 

Besides i can just go nuts with loosening useless cl and twcl to tighten everything else up anyways

 

Also is there a list for standard spd profiles?

 

 

Personally i wont bother since the only laptop i have is ddr3 and i am not planning on buying a newer laptop, problably just gonna cram desktop parts into a suitcase, add a 20-24 inch or whatever behemoth lvds tv monitor screen, make some sort of battery pack, and call it a day cause i do not want garbage laptop throttling and honestly having a carryable desktop is quite intriguing for me since i really dont like having to be fixed to one spot of the house, also just the swagger of carrying a behemoth of a laptop like its  a suitcase, but ill make a topic or 3 about that later
