Poutoux,

Je suis en cours d'acquisition d'un OUVIS AMR5 ryzen 7 5700U 16g 512g.
J'ai l'opportunité d'upgrade la RAM par 2 modules :

CT16G4SFRA32A.C8FF
&
CT16G4SFRA32A.M16FR

Pensez-vous que ce soit compatible ?

Déjà je ne sais pas si les CT16G4SFRA32A poseraient problèmes.
C8FF ≠ M16FR me trouble encore plus.

Merci de votre aide.

if i were you i'd get a kit that is dual channel ready/certified (identical) as dual channel will yield better performance. if you can't, out of the two choices you listed, i'd get two of the M16FR sticks (dual rank) for a total of 2x16GB=32GB

CT16G4SFRA32A.C8FF specs

you can read more on single/dual rank here

But if you are only using two slots (due to limited RAM slots) it is better to have two dual-rank sticks, so that you can have a dual-channel, dual-rank setup and utilize the increased bandwidth together with the interleaving ranks.

crucial is a reputable brand and the spec/timings of CT16G4SFRA32A are identical to the TEAMGROUP kit TED464G3200C22DC-S01 i bought, which runs just fine: DDR4-3200 (PC4-25600) CL22-22-22-52 1.2V

Thx !
Unlikely, TEAMGROUP seems not be really sell in Europe
Fast query on Idealo only found me a 270€ set
Last thing, I already found 1.35V set as TEAMGROUP Zeus.
Is 1.35V works with 7 5700U ?
Is it really useful ?

ouch.. yeah crucial will be easier to source, i just gave you an example of the kit i am using and the specs look to be identical to the crucial one you're looking for. Also my kit was 2x32GB hence the higher cost.

I would stick to the standard DDR4 SODIMM voltages of 1.2V as it doesn't really make that much sense to overclock the AMR5 (even if possible in the BIOS)

here's the 2x16GB teamgroup kit same as mine but 32GB, quite a bit cheaper than the crucial 2x16GB

Merci infiniment !
