SDRAM 133-7,5 8chip in 133-8 16 Chip

Finta je, katerga ti matična plata podpira. 256 MB 8 čipov ima 32MB čipe (256MB/8), 256 MB 16 čipov ima pa 16 MB čipe. Če ti plata podpira 32MB čipe ti bosta oba delovala. Ne vem sicer, če je kateri od njiju hitrejši.
Jest sm imel tak problem: nabavil sem 128MB SDRAM s 4 čipi in ga je matična zaznala le 64MB, ker pač ne podpira 32MB čipov, le 16MB. Zdej sm pa zamenjal z 8 čipi in bomo videli, kako bo delovalo.

Evo, tole piše pa na Vikingovi strani:
"Many PC133 modules are built with higher density SDRAM chips that are not supported by older PC100 systems. These high density (256Mbit chips) require an extra address line that older systems do not support. This would mean a module built with the 256Mbit chips is not compatible with older PC100 systems.

As a general rule, if you have an older system (PIII built with an 810 chipset or below) you will require a 128MB module built with at least 8 chips, or a 256MB module built with at least 16 chips."

Ja, poskusi s 16 čipi. No, jest dobim 128MB 8čip enkrat drug teden, potem pa lohk napišem, kva bo plata nardila z njim.
Ja, res so z več čipi dražji, na žalost..

7.5 = 7.5ns ~ 1000/7.5 = 133.3MHz RAM
8ns ~ 1000/8 = 125MHz

Vedno vzami ram, ki zavzema dve banki, ce kupujes SDRAM.
