32GB DDR5 RAM, 4800MHz CL40 Laptop Memory

[beardedragon]

I have a Peladn Mini PC running MX-Linux. It came with 16GB RAM and wish to upgrade to 64GB. What would be the best memory to buy from Amazon? Below find a long list of specs from my computer.

[dont whant to set it"']

Hello and Welcome to TPU.

A quick search got me that the 6900HX CPU in your unit has a rated memory controller for up to 4800MT DDR5 and 6400MT LP-DDR5.

Depending on what spec it got manufactured to make use , very likely you have to go for same standard DRR or LPDDR.

It's not like some older versions of the DDR standards where LP-DDR is pin compatible with DDR. Some newer models can be with either LP or standard, certainly not mixable , not switchable.

Which Amazon? Fr, It , De, US ,UK ...

 

[beardedragon]

Us Amazon. Does this mean I could use a faster RAM like 5600 MHz?

LPDDR is not a product that comes in DIMMs. It is the faster and lower power option, but usually not an upgrade option as it's soldered down. That's the tradeoff in the past few gens of mobile Ryzen when deciding between the two - expandability vs iGPU performance and possibly idle platform power.

One could imagine that it could function similarly to desktop (can always fallback on a lower jedec speed manually or automatically), but with the way mobile (including mini PCs) BIOSes are stripped down, I'd just stick with 4800. Rembrandt also falls into something of a hole due to being mobile only, the UMC is not quite as well understood as its predecessor or successor even though it works similarly to the latter.

If your system is upgradeable = DDR5, not LPDDR = you are already on the lower performance option (at least in terms of iGPU performance potential). There's no point trying to risk compatibility and other issues just trying to squeeze in a few hundred MT/s freq that will make no difference on this platform. DDR4/5 on SO-DIMM is not really the performance route in any case, as even with higher speeds it's still all just JEDEC (horrendous timings), vast majority of laptop BIOSes aren't set up to do any more than train the basic JEDEC timings. Just buy whatever kit is cheapest that meets the DDR5-4800 standard.

Thanks. I plan on staying with 4800MHZ.

Any recommendations for RAM?

Any recommendations for RAM?

Depends where you are and where you prefer to buy usually, I guess. To err on the safe side I would probably stick with Crucial (Micron) for SODIMMs. There are other trustworthy brands as well but they spring to mind. Especially now that mobile/industrial are really the only remaining applications in which you would ever want to buy Crucial anyways, since they retreated from the desktop consumer market.

I have found some Crucial RAM on Amazon. I have used Samsung for one of my 1TB NVME, the system. Crucial is more affordable that Samsung. I will buy Crucial. It seems the Adata RAM is out of stock, which is the brand used by the manufacturer. It cost twice the amount for Crucial RAM. After I install it. I will comment here. Thanks.

Crucial DDR5 4800 32GB "added" to Adata DDR5 16GB and it all works. Thanks you for your advice.
