what memory will fit ASRock P4i65G??? help!!

  m117chief 22:22 08 May 2007

As some of you know i own a ASRock P4i65G now and things are great but ive bought some memory for it and it dont work!!! All the manual says for the mobo is Dual channel DDR memory, 2 x DIMM slots, Support DDR400/333/266, max 2gb. Thats it, is there more info on this at all?

What ive bought is (this is what is says on the memory stick) DDR 128x8 PC400 1G AUM1107. The advert for the memory said,

PC3200 400Mhz 1GB 184pin
l 184-pin unbuffered DIMM
l Density: HIGH
l Maximum 6.4GB/s bandwidth
l JEDEC standard 1.8 +/-0.1V power supply
l 128x4 x2 component configuration
l CAS Latency 3
l 4 Bank
l Off-chip driver (OCD) impedance adjustment, and on die termination (ODT)
So any ideas why this memory wont work please!!

Are you using it on it's own or with your old one? they may not be compatible or as happened to me once I got a bad stick and once replaced I had no problem.

no i bought 2 the same, came in same pack. so i have 2gb which is mobo's max amount. They are brand new sticks.

Have you tried them 1 at a time to see if one of them if duff.

I know nothing about RAM but Crucial specify click here

1GB, 184-pin DIMM, DDR PC3200 memory module

Module Size: 1GB
Package: 184-pin DIMM
Feature: DDR PC3200
Specs: DDR PC3200 • CL=3 • UNBUFFERED • NON-ECC • DDR400 • 2.6V • 128Meg x 64

The only obvious difference between that and yours is the voltage though I don't know if that means anything.

What make is your RAM?

Hi yer i have tried them singlely, no joy. MAke, well they dont have a make on them or the site. It is cheap (blush) but really should make any odds, ive always used cheap memory with no troubles.
This is what ive been told

"Did you make sure your system will take 128x4 density memory modules - which
is called High Density Modules. Not every motherboard works with them. 128x8
has more compatibility than 128x4, but it is also high density module." and "128x4 we know that
main issue could be either older bios..."

How can i check my BIOS? and how do i find out if my mobo takes 128x4 high density??? my head hurts.

Hi, you should run the Scan from within beeuuem's link - this will tell you exactly what RAM you have and what you can/should use.

  m117chief 18:09 09 May 2007

Ive ran the scan but not much to go on really. dosnt tell me if i can run high density or not. im sure ill get there.
