RAM: High-Density, Low-Density...???


Recommended Posts

Sorry to be-bop into here; I don't normally do hardware, but I'm the default research and analysis one, so here goes.

 

Does the LP 875P-T take low-density RAM or high-density RAM? I'm trying to make sure we've got the right RAM, as it's only reading 1/2 of 2Gb we just added. He games, I do 3D rendering - RAM's important.

 

Any help or info y'all could offer would be greatly appreciated. I'm about ready to bite something, and not in a good way.

The RAM's generic; here are the product specs:

 

Product Description

 

Single 1024MB (1GB) DIMM

PC3200 400Mhz DDR Memory

Chip Configuration: 128x64

Chip Density: 128x4 (High Density)

Unbuffered, Non Ecc, Non Registered

Voltage: 2.5V CAS Latency: 3

Double-Sided With 8 Chips Per Side

184 Gold-Plated Pins, SPD Support

 

"Guaranteed compatible chipsets: VIA P4X266A - VIA KT400 - VIA KT600 - VIA PT800 - SIS 645 - SIS 648 - 648FX - SIS 746FX plus any other board that supports the specifications above

(excludes ASUS motherboards)"

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(Yeah, it was an eBay purchase; I've had really good luck, for the most part, with my eBay electronics purchases, so this seemed reasonable).

 

As for the board's BIOS version...I'm running into an issue trying to figure that out. I don't see a place for it when I go into the BIOS (I am so out of date with dealing with all this, BTW - but I type better than he does, so I got stuck with this part of the troubleshooting; please bear with me). I do know that we haven't updated the BIOS since we purchased the board last summer, so it's probably original manufacturer BIOS.

 

From what I can tell from the description on the site, the MB is Revision R.AC0 - I can't tell which of the files listed on the BIOS section for this board might be applicable. The current BIOS build date is 1/25/05, if that's any indicator.

 

Again, any advice, etc. that you could offer would be greatly appreciated. I'm aces when it comes to the software side, but I got out of hardware 10 years ago, and very seldom venture back to the dark side. He's enthusiastic about it, but a newbie, so...yeah. Here I am.

It appears your problem stems fromChip Configuration and Chip Density:

Chip Configuration: 128x64

Chip Density: 128x4 (High Density)

 

Most 1Gb memory modules are configured 64x8 chip densities.

 

Can you take a picture of the memory modules?

 

I have a strong feeling that they are probably double the height of normal modules.

Well, the significant other and I have an understanding; I don't crack the case, and he doesn't whimper. That being said, it is a plexiglass-sided case, so looking at the memory in situ, it appears to be the same general height as the previously existing RAM, which is in slots 3 & 4, if I'm reading the board right. All the RAM have heat sinks on them, which makes it a bit more difficult to tell, but I'll see if he minds looking.
