| 286448 | 2004-10-31 03:16:00 | Hi, one of my computers are failing, after a mem test proggie found it ... OK, I had a look at my motherboard manual and it says it it accepts EDO (2 banks) or PC100 SDRAM (3 banks). It mentions EDO at 60ns is the faster one in the manual. Is this true? I've always thought the PC100 was faster. The most it accepts is 2x 128MB = 256MB (EDO). Or, 3x 64MB for PC100. I am thinking of the 2x64MB (SDRAM). Doubt I need more at the mo, trademe would be good for this, if the guy has used mem test for it .. |

| 286450 | 2004-10-31 04:59:00 | Hi Nomad, i am also in a similar situation, wanting to replace/upgrade some ram in my friends system, and was about to post, however thought i may as well keep my question here with yours as its related to sdram too ;-), hope you don't mind. The sytem i am upgrading takes in 3 slots, either: non-ECC SDRAM ("PC100" 100 MHz);up to 128mb or ECC SDRAM ("PC100" 100 MHz) up to 256-MB. My question being, how do i tell the difference between "non-ECC" and "ECC" ram? I can't see anything on the ram in it at the moment that tells me? (as i have another old stick that has "non-ecc" printed on the sticker on the ram). And as i have to use only one type, would like to know how to distinguish them when buying etc... Does the fact it doesn't say "non-ecc" on it mean its "ECC"? Or is there something i can identify it by? Thanks :) Thanks |

I have never held a ecc stick of ram ever and I 've handled a lot of it. If I remember correctly ecc ram has an unsual number of memory chips on it something like an extra chip per side. |

| 286452 | 2004-10-31 08:27:00 | "In order to check and correct the memory, additional RAMs are required. A non-ECC module which has eight RAMs would need to have a ninth RAM added; a sixteen RAM module would generally need to have TWO additional RAMs added. Obviously, the additional RAMs make the module more expensive." from here www.corsairmemory.com |

| 286453 | 2004-10-31 08:51:00 | ECC ram is also "Generally" Clearly marked as such as, a safe guide, used ram, not clearly marked, should be regard very cautiously. The the problems with Ecc ram do not end there. I have one genuine 128 Ecc ram stick that is not genuine to the machine it is installed in, 2 machines of that brand refuse to recognise this 128 stick above 64 meg, it is twin sided. In anothet machine that recognises the 128 meg, mem test, 100%. Ecc boards can be very touchy about this. D. |

| 286454 | 2004-10-31 20:14:00 | Thanks Highlander & drb1, most helpful. I had a feeling that the normal/common ram in use was non-ecc, as you guys have pointed out ;-). Better safe than sorry though, as i was looking at getting her to get a 256mb stick, however, now i know that we can only put max. of 128mb in ;-). Thanks and sorry to sidetrack your thread Nomad, cheers :-). |
