Vista RAM score went from 5.9 to 4.5 and RAM seen from 3.5 GB to 3.0GB

This occurred after I pulled my 2x2GB BUffalo PC5300 sticks from the Dell Inspiron 1520 (T7500, 8600GT etc) and stuck them into the Gateway P-6831FX (T5450, 8800GTS). 4.5 was the experience score that initially got with the 3GB RAM installed in the Gateway from the start. Why would my score drop that much? Does that drop really mean anything? Why is Vista on the gateway recognizing less RAM? They are both Home Premium versions.

At first I though the sticks were not running at dual core in the gateway, but CPU-Z says they are running at symmetric dual channel speeds although it only rates the DRAM frequency at 333 (shouldn't it be 667 in Dual Channel)?

 

Double Data Rate, 2X333=667 (almost). As to why your score is lower I don't know but hear that score is meaningless. If concerned benchmark memory bandwidth with SiSoft see how much diff.

 

dont trust wei because it says all ram is 4.5
my dell desktop ddr 1gb 333 score 4.5
my acer 3680 with 1gb ddr2 5-5-5-? 533 4.5
same acer with 2gb ddr2 4-4-4-12 score 4.5
my hp notebook with 2gb ddr2 667 5-5-5-? 4.5
now my hp notebook 4gb ddr2 4-4-4-12 667 4.6
gateway desktop 1gb ddr2 800 guess its 4.5
this is all garbage their must be a difference between them

 

I'll try 3dmark and a crysis benchmark and see if it gave me a boost in performance, if not I'll just sell the RAM on here or on ebay. Does anyone know why my gateway recognizes less of the ram than the dell?

 

it can be that the mother board only supports 3gb and if u want the full 4gb you need a x64 os

 

Not true, I have 2Gb of PC3200 corsair memory in my desktop replacement, and Vista Ultimate gave me 5.5 for my memory score.

Your Gateway has 8800GTS and probably reserves all the memory space above 3GB for the video card. You will need a 64-bit OS or Linix to see all 4 GB.
Slower CPU plus less memory (seen from the OS) will result in lower score.

 

Which type of RAM is best 677 RAM for notebooks, assuming that the M17X can take 677, possibly 800, would Corsair or Crucial be better as both appear to be the same speed, Latency etc.

 

Does not matter, both the same.

 

I don't think your processor can even score 5.9, not to mention the memory modules.

 

Your processor is holding your memory score down. I put a T9300 in mine and the memory score went to 5.1. Base score is 5.1, processor 5.4, graphics 5.9, gaming graphics 5.8, hard disk 5.2. So if you upgrade the CPU your memory score will rise.
