question about RAM

[v2s13]

---

bro nag dual channel ko ako pc rn 2x1gb kingston ddr2 800mhz values series sa kingston. naa ko plan mo palit 2x512mb geil ddr 800mhz.
advisable ba ni? unsa effect ani if nka dual channel ko ako 2x1gb and ma dual channel sad ko sa 512mb? naa negative effect?
advisable sad ba mo upgrade 2x512mb ram na ako ram na gamit 2x1gb dual channel na. really nid your opinion kay nag libog nko, knhanlan mo gawto ko sulitun jd, wai mahay2x. heheheh

the only way to trully harness your rams

is tinkering with the bios settings

especially the timings and FSB


you have a 2 x 1GB kingston ddr2-800mhz

download cpuz: http://www.cpuid.com/cpuz.php

and you will get all the data on your ram, FSB, Cpu frequency etc.

The figures you want to know are:

is your memory running at 800mhz? or 667mhz? or 533mhz?

next is the FSBDR ratio

is it 1:1 or 4:5 or 2:3

you can adjust them in the bios of your motherboard.

dli bro, 800mhz ako ram. kbaw ko ana. ask lang ko if unsa mahitabo if mag dual channel ko sa 2x1gb nya mag dual sad ko 2x512mb sa lain slot. naa ba mahitabo ani?

you will have 3gb of memory

if your OS is windows XP Pro.... that is already too much... 2gb will only show little improvement compared to 1gb windows XP


but if you are using Microsoft Vista Premium.... then 2gb is the minimum adding 1gb would be better....

it will still work on dual channel.

but its important to match all the rams you are using... if kingston... then same kingston model for all rams...

if you don't use matched pairs then performance will depend on the slower ram.....

so if the kingston is slower.... the geil will match the kingston and it will also slow down to the level of the kingston

tnx bro. mo matter na CAS latency if different? so ma dual channel ang duha 2x1gb and 2x512mb? tnx for ur help bro.

[Zirv]

yup cas latency should be matched

or else the slower latency will be used by the motherboard

it will still be dual channel.

i believe you should make sure that they have the same CAS lantency. i think kingston value ddr2 800 is clocked at 5-5-5-15 while geil modules usally clocked at 4-4-4-12.

[emoners]

@spookey: Actually bro...the DDR2 Geil Value RAMS are at CAS 5-5-5-15 while the Geil Ultra & Esoteria are at CAS 4-4-4-12.

Mga bossing, noob question lang po... sa latency bah (or unsa tawag ana.. the "4-4-4-12" thing..), mas maau ang higher ani or ang lower?
