single rank alebo dual

Jaký máš procesor a desku?

intel pentium G630 a doska gigabyte h61m-s2pv

Klidne nech [Single]-chanel, v tvém pripade je rozdil minimalni a blyzko nule.

ok dakujem tiez som tak uvazoval

len nechapem preco je single drahsia nez dual

Protoze u Single musi vse osadit jen na jednu stranu.
Ale je rozdil Rank a Chanel.

ako to myslis? nerozumiem tomu prepac

Ranked strana osazeni pameti
Chanel = je pocet osazenych RAM : quad = 4x , dual = 2x RAM, Single = 1x RAM.
* Kdyz pises ze chces kupovat jednu, nebo dve RAM, tak se bavis o Ranked, nebo Chanel ?

Tak ji vem.

a potom casom ked budem chciet kupit k nej dalsiu 8gb alebo 4gb tak musi byt single alebo dual?

Na Dual-Chanel potrebujes 2xRAM stejné kapacity.
Nemusi byt Single nebo Dual.

ok diky pekne

- Na Dual-Chanel potrebujes → 2xRAM stejné kapacity. Na single → Ne
- Vyhoda Dual-Chanel je ta, ze ti zdvojnasobi sirku pasma, kterou vyuziva treba IGP|APU (integrovany graficky procesor). Mimo IGP|APU je jinak rozdil vykonu na beznou cinost priblizne stejny bez ohledu na pouzity [Single/Dual].
- Jestli mas 4+8Gb tak muzes/musis zapojit jen SINGLE. Kdyz mas dve 2x RAM stejne kapacity, jako 2x4, 2x8 etc tak je "muzes" zapojit do Dual-chanel protoze to podporuji, protoze mas dve RAM stejne kapacity, ale muzes zvolit i Single .
* Od samotného HW zapojeni zalezi od DIMM slotu (kam davas ty RAM). Které maji urcité barvy pro Single a Dual. Dejme tomu v prvnim+tretim = dual chanel, ale prvni + druhy = single chanel). Coz ti umozni zapojit i 2x8 v Single chanel.

ja mam len dva sloty takze 8gb+4gb

Ranked strana osazeni pameti

Pozor na vyrazy: Double Sided a Dual Rank.

Single Sided a Double Sided (SS/DS) je fyzicke usporiadanie chipou, na jednej/dvoch stranach RAM modulu.
Single Rank a Dual Rank (SR/DR) je elektricka komunikacia modulu z radicom.

Singe Rank Memory can be memory with chips on only one side of the stick of memory, however Single Rank Memory can also have chips on both sides of the Stick as well.

The number of ranks on any DIMM is the number of independent sets of DRAMs that can be accessed for the full data bit‐width of the DIMM ie 64 bits. The ranks cannot be accessed simultaneously as they share the same datapath. The physical layout of the DRAM chips on the DIMM itself does not necessarily relate to the number of ranks. Sometimes the layout of all DRAM on one side of the DIMM PCB versus both sides is referred to as “single‐sided” versus “double‐sided”. These terms may cause confusion as they do not necessarily relate to how the DIMMs are logically organized or accessed.

Nevim na co presne odpovidas, (na "Ranked strana osazeni pameti" ?), ale notak, [RANK] je prece velikost a pocet pametovych cipu a jejich usporádání do tak zvanych "ranku" (osazeni stran, oznacené 1R→ Single nebo 2R → Dual). O S/R nic uvadim.
* Strana osazeni neni podminkou, ale zpravidla to tak prodavané je SS → Single DS → Dual (S=znamena jen strana), .. tedy az na quad rank pro servery
