Default Compatibilitate memorie (downclock?)

Asa... o intrebare poate stupida, dar ar fi o idee sa cumperi un kit de memorii care au o frecventa mai mare decat cea la care vrei sa il folosesti si sa ii faci downclock?

De exemplu kit de 4000cl18 rulat la 3600cl16 sau 3200cl14 etc?

A incercat cineva sau nu merita riscul?

Bine inteles ca merge, dar... de ce ai vrea sa faci asa ceva?

Edit: Sau s-o zic altfel, orice memorie vanduta tre sa respecte standardele JEDEC care pentru DDR4 incep de la 1600Mhz.

Edit2: Orice memorie 4000cl18 merge la 3600, dar nu neaparat CL16.

Ca si la OC, nu ai garantie ca vor functiona la parametrii respectivi. Trebuie incercat. Daca ai noroc, e posibil. Daca dai de niste samsung b-die mai rasarite e posibil sa mearga si 3600MHz cl14 la 1.45V.

Legat de memorii, daca am unele care cer 1,2v si xmp le duce la 1,35 nu vedeti o problema? Poate asta e rationamentul pt care cineva poate achizitiona niste memorii 4xxx ca sa fie sigur ca la 3600 ii merg cu 1,35v, nu cum zicea cineva mai sus cu 1,45v. sau poate vrea sa aiba latente cat mai mici la 3600.

In mod normal producatorul le testeaza cu profilul XMP, ca altfel nu s-ar lauda cu el.

Edit: Eu inteleg ce vrei tu, dar atat timp cat un producator nu vinde 3600 CL16 @1.35V n-ai cum sa stii cum merg memoriile alea, si la ce voltaj, pana nu le testezi tu, cu mana ta, pe placa ta de baza. Chiar daca cumperi unele 3800 CL18 1.45v si le faci downclock, posibil la 3600 sa ceara tot 1.45V, sau sa nu mearga cu CL16.

Daca vrei sa fii sigur, ori cumperi fix ce-ti trebuie. Ori, desi nu-i 100% sigur, intrebi pe forum "are cineva vreo idee de memorii 3600 CL16 sa mearga cu 1.35V" ?

Am cum sa aflu ce memorii are kit-ul doar din codul / serialul lor? N-am cum sa le montez momentan, astept sa intre 5950x in stoc, dar as vrea sa vad ce sunt.

Da, din serial ai cum, daca magazinul ti-l da in prealabil, trebuie sa il aiba efectiv pe stoc si sa il mai si comunice
