| 292152 | 2004-11-14 21:56:00 | This Motherboard says it supports DDR 400/333 184-pin DIMM and does NOT support double-sided x16 memory. What RAM stick should I get? What does the 400/333 mean? Can I get a DDR 400 PC3200 ram stick? Cheers |

| 292153 | 2004-11-14 22:44:00 | tha'ts what it's telling you yes.......however when you buy it make sure that it's not double sided.........lol | drcspy (146) | ||
| 292154 | 2004-11-14 23:40:00 | What's the motherboard in question? I find it interesting that a board will support DDR400 chips but not double sided. | alphazulusixeightniner (185) | ||

I'm looking at this mb: ASUS P5GD1 Pro, haven't bought it yet, though. Downloaded the manual and it says that : "DIMM modules with 128 Mb memory chips or double-sided x 16 memory chips not supported." |

| 292156 | 2004-11-15 00:36:00 | It's designed for DDR400 RAM so it would take anything reasonable you put in it, like 2 x 256mb or 2x512mb. I think the limitation it is talking about is putting 2Gb memory sticks in. | alphazulusixeightniner (185) | ||

If the manual says that then it would be a good idea to do what it says. It would also be an idea to ignore alphazulusixeightniner, no offence intended but the motherboard manufactuer probably knows more about there product than he does. There will be a good reason why they put the above warning in the manual, they dont just do it for fun. |

There will be a good reason why they put the above warning in the manual, they dont just do it for fun. From this satement: "DIMM modules with 128 Mb memory chips or double-sided x 16 memory chips not supported." 128MB memory chips not supported... How many memory chips on a stick of RAM? 8 chips for one sided? 16 for double sided? 128MB x 8 = 1024MB (so don't stick a 1Gb stick in) 128MB x 16 = 2048MB (so don't stick a 2Gb stick in) Are most new 512mb sticks double sided? I seriously doubt a new Intel 915P chipset can't handle 2 x 512MB sticks... but if the manual says it, who am I to argue. |

"or double-sided x 16 memory chips not supported" perhaps you need to read that closer? ASUS arent ****wits they know what their motherboard can and cant do. Unless your currently working for ASUS designing motherboards i'd tend to trust the manual before i trust you. The new Intel 9XX chipsets are widely regarded as dogs, if they couldn't handle dual sided dimms it wouldnt surprise me. |

| 292160 | 2004-11-15 02:16:00 | And just to confirm that I'm not talking BS, read the Motherboard manual (www.asus.com). "You may install 256 MB, 512 MB, and 1 GB unbufferred, non-ECC DDR DIMMs into the DIMM sockets..." Then it goes on to list numerous manufacturers RAM modules that are compatible including about 50 512 MB and 1 GB sticks that are double sided. But don't listen to me, I just read the manuals, I don't make the motherboard. :D |

| 292161 | 2004-11-15 02:21:00 | If a manufacturer says there is a limitation, it usually exists. :D I've owned two laptops whose manufacturers mentioned memory limitations. The Tandy's memory could be expanded to 4MB (with two 1MB 30 pin simms). I tried a couple of 4 MB simms, to get 10 MB. No go, they'd left out the address lines. :_| A more modern Compaq could take 96MB ... 32MB on the mother board, and a 64MB in a socket. And it would use the first 64MB of a 128 stick I tried. They'd left out the address lines. :_| In this case, it's probably not enough drive on the address and data lines to the sockets to handle the input capacitance of 16 chips rather than 8. It's the sort of thing which would "nearly" work, because it would cause timing faults. You might be able to make it work by slowing the memory down. Of course they might have left out the extra address line, too. :D |
