How to read Crucial memory part numbers?
Can someone explain what's different about these two Crucial memory
sodimm modules: CT32M64S4W7E CT32M64S8W7E I understand 32M64, but what's the difference between S4 and S8? Crucial used to have an explanation online, but damned if I can find it now. Thanks!! |

Non-parity . 133MHz . 3.3V . 32Meg x 64 . Seem to be identical specs. Phil Weldon They're not identical. One is high density, and the other is low density. To tell the difference, one speculative technique, is the part number printed on the bag. I offer these two pictures, as a means of guessing at the difference. CT32M64S8W7E.8TDY ".8" = 8 chip version = high density = not for 440BX chipset http://c1.neweggimages.com/NeweggIma...148-027-02.jpg CT32M64S4W7E.16FGY ".16" = 16 chip version = low density = OK for 440BX chipset http://c1.neweggimages.com/productim...148-026-02.jpg The best way to avoid problems, is to use the Crucial search engine to get a part number. But for prebuilt computers (Dell, HP etc), the part number returned is not a generic "CT..." type number, but a number only for a limited number of prebuilt computers. And then it becomes even more difficult to tell what you're getting. Basically, the idea is, you pay a premium for product knowledge, which the vendor withholds to make more money. As consumers, we could break this system, by posting images of each proprietary product offered, but that isn't likely to happen any time soon. And heat spreaders with warranty stickers on them, to seal them, is another technique to obfuscate the product knowledge. Paul "nospam" wrote in message . ..

CL=2 . Non-parity . 133MHz . 3.3V . 32Meg x 64 . Seem to be identical specs. Phil Weldon Thanks Phil, but I think I finally stumbled on the answer, or at least half the answer. S4/S8 refers to chip density: S4 = 128Mbit chips, 16MB x 16 chips = 256MB S8 = 256Mbit chips, 32MB x 8 chips = 256MB Apparently Crucial had so many compatibility issues with the 256Mbit chips ("high density") they stopped selling them. Or at least I think that's the case (that's the half I'm not sure of). |

That's the incompatibility I was referring to. Also, Crucial's online memory selector program no longer has any S8 parts, but I did see three S4's. |
