RAM Buying advise
can anyone advise me on how to buy ram from ebay ..
There's getting to be all kind of different types IE. SIMMS DIMMS SDRAM and I'm a bit in the dark in terms of things like bus speed downward compatability. Can I buy a higher bus speed thtn I need so that I can use it in a machine I might purchase in the future? specifically I' presently looking for 64 -128 Megs for a compaq deskpro 4000 mmx (168 pin). I'm looking for "pre-owned" RAM for my pre-owned computer.. I don't want to spend more on the ram than I did on the box. It's mostly for an internet dialup internet hookup but 32 megs of RAM is making it a real Tortoise (and killing the HD). So I was hoping to gain some insight into type compatability before I buy.. I'm wondering even though crucial and compaq say advise using up to 128 meg chips is it possible to go higher to say 512 since the technology has advanced since then it seems I need pc66 non parity up to 128 meg SDRAMs but I'm wondering can I use pc100 or pc133 etc. or even higher. and should I accept or reject ECC even if it's real cheap.. (I know it's slower but will it work?) |

I would not recommend buying RAM for a Compaq from anywhere you can't return

er.... www.crucial.com Specifically, see http://www.crucial.com/library/sfiles6.asp which says, in part: "You can use PC133 memory in a PC100 system and you can use PC100 memory in a 66MHz system. However, the memory will only run as fast as the motherboard is capable of handling. For example, your PC133 module will run at PC100 speed in a system with a 100MHz bus. "Some people will buy PC133 memory for systems that don't support PC133 SDRAM with the intent to upgrade the system at a later date with a motherboard supporting PC133 memory. That way, you can simply take the memory out of your old system and use it in the new one." |

WHich, unfortunately, is not always true on some models of Compaq.

The link I gave isn't always true?

The link I gave isn't always true? Correct. There are MANY laptops spec'ed for PC100 memory that absolutely will not BOOT with PC133 memory installed. So the concept of buying PC133 memory to use in your current laptop in order to use it in your next one when you upgrade is seriously flawed. Besides the fact that most of us buy less than incremental increases in our laptop upgrades, e.g. going from a PIII 850MHz to a Pentium M 1.5GHz. One used PC100 memory, the new one uses PC2700!

PC133 256mb sticks did not run in my 5660, just as Tom said.
