| 289503 | 2004-11-08 20:56:00 | I bought a new VDATA 256MB 400DDR module which appears not to be performing correctly in a Asus P4V533-MX motherboard (1 ram module) with 2.66GHZ chip. Tested using both XP Home, and 98se, Windows reports the ram size as 239 MB, which for a start is odd. Aida gives the following test scores: P4CPU Motherboard Chipset Latency Read Speed Write Speed This Computer Asus P4V533-MX P4M266A 200.6 ns 1174 MB/s 266 MB/s These test scores seem to be similar to that of 3 year old hardware. Other benchmark software also shows very weak results. I appreciate any help you can give. Peter. |

| 289504 | 2004-11-08 23:20:00 | The Windows report tells me that you have an on-board video interface, which shares 16MB of system memory. :D As for the speeds ... DDR's not obsolete yet, so I don't own any of it. :D |

| 289505 | 2004-11-08 23:37:00 | Good point about the ram size! Thanks:-) The reported speed is (just) above my other machine a celeron 500mhz SD133 ram, so im not really at the complaining stage, but its disconcerting to think that the memory read/write speeds are only about a third of what they should be. Aida says a cpu / ram combo like mine should be reading memory at least at 3560 MB/s Could this just be cheap ram, and i should just get over it, or is the high latency a sign of a dodgy module? I cant find the contact details of the guy i bought it from. P. |

| 289506 | 2004-11-09 02:22:00 | Could it be that the ram is DDR400 when the fsb is 533 Meg? If the ram was matched wouldnt it be DDR266 ram? Or doesnt it matter if the ram *can* run faster? | webwiznz (6374) | ||

Shouldn't matter... the ram should just clock down. Perhaps you need to look at whether there are other items such as spyware infecting your PC which could be slowing it down? Also, have you made sure you have installed all your relevant motherboard drivers? Lo. |

| 289508 | 2004-11-09 02:46:00 | The memory should be OK for a 533 fsb mobo. I use DDR 400 on a 533 fsb mobo here. According to the ASUS site this mobo (yours), only supports PC2100 (266), and PC1600 DDR 400 ram is PC3200. This mobo doesnt state that it supports DDR 400 ram. It might be creating a bottleneck or something? |

Its a brand new os install > Also, have you made sure you have installed all > your relevant motherboard drivers? Im pretty sure, yes. Ive done a bit more reading and wondered if someone had been fiddling with the bios settings, so checked the various ram settings in bios. They are all set to default values. Im still puzzled. |

| 289510 | 2004-11-09 10:43:00 | can you borrow another stick of ram and repeat the test ? Adata ram doesn't have the best reputation (downright crappy)and it could be you have a dodgy stick. | the highlander (245) | ||
| 289511 | 2004-11-09 10:45:00 | Bugger its vdata (I'm going blind) but a quick look seems to indicate this is very cheap stuff so the advice stays the same. |

| 289512 | 2004-11-09 23:15:00 | No mate, your spot on. AFAIK A-data *make* v-data ram...er, i think v-data is their poor cousin. So i guess i got what i paid for at $65. I heard that 384MB is the optimum ram quantity for win98se so maybe ill pick up a 128M module and test that and later add it to the 256M module. Do they all need to be ddr400 or can i mix 400 and 266 ram? |
