| 164347 | 2003-08-01 03:13:00 | Cutting a long story short: Need more ram. Checked ram in the machine and it said: M2025664DS 88ADG758 256Mb DDR 266MHz CL2.5 PC2100-25330 DIMM Okay, no idea what half of this meant, so I bought this: Kingston 512Mb 266MHz DDR PC2100 Reg ECC DIMM CL2.5 Now the 266MHz is the same, the PC2100 is the same, they are both CL2.5 and both DIMMS. It fits, but it doesn't work. Not seen with 256Mb in there. PC just beeps and has a fit when remove 256Mb and put 512Mb in same slot. Thought I was buying non-ECC, can't tell if original was ECC or not but think it wasn't. What the heck do I do? I thought I knew what I was doing with PCs, but now I am beginning to wonder. I built this machine from components, and I have a box full of bits and manuals somewhere, do I need to find it? I don't know if there is any info about the memory in the box. robo. PS anyone want a slightly used 512Mb memory module? |

| 164348 | 2003-08-01 04:17:00 | The 256MB DDR is NON-ECC (guessing) the 512MB DDR is ECC, problem I'm also guessing is a mismatch. The BIOS also may have an option to let it know if it's using ECC or NON-ECC although I'm positive you can only select one or the other for it to choose. ECC is more expensive that NON-ECC and Kingston is a good brand name too so add goodwill onto that. Just have a look in the BIOS for ECC memory checking. That may solve the 512MB but running both of them I doubt. |

| 164349 | 2003-08-01 04:34:00 | The ECC stuff is generally used in servers where accuracy is vital more expensive and hopefully your Mother board will support it if not take it back and explain the situation | kiwibeat (304) | ||
| 164350 | 2003-08-01 04:34:00 | I think it must be the ECC thing, but damn it is hard to find the right stuff. Will check the bios, be surprised if ECC would work. Doesn't go in my work PC either, didn't try removing the other module first but it had a fit too. robo. |

| 164351 | 2003-08-01 04:59:00 | The 512Mb Dimm may be 'registered' ( i.e. the Reg ) in the description and your mobo may not support registered Dimms. | wuppo (41) | ||
| 164352 | 2003-08-01 05:46:00 | Nahh, I am pretty sure it is the ECC vs Non-ECC thing. Can't believe it. Got a SODIMM by accident the first time, that was non-ECC. The whole process makes me feel like a complete woofter. I can't believe you have to check like six different things to get the right memory, made looking for it on the web an absolute mission. robo. |

| 164353 | 2003-08-01 05:49:00 | Well if it's registered, it certainly won't work in conjunction with a non-registered (unbuffered) DIMM; you can't mix them. What are the model numbers of the new DIMM and your mobo? | wuppo (41) | ||
| 164354 | 2003-08-01 06:55:00 | ooh crikey, i'll have a look but may take some time finding mobo model. robo. |

| 164355 | 2003-08-01 07:07:00 | If you can't find the manual look between the PCI slots or one corner of the board for model & rev number. Cheers Murray P PS. Checking mine to see if any take/use registered or ecc dimms ;\ |

| 164356 | 2003-08-01 07:10:00 | to see if its an ECC problem go into the bios and make sure ECC is turned off. not many non-server pc's support or use ECC proberly. check what the mobo can actually handle. it simply may be a faulty ram stick or incompatable with the motherboard. |
