I just bought 2 x 256's for my computer to now equal 1.5gb of RAM. my original was 2 x 512's.

my System performance rating went from 3.1 to 2.0, dropping my rating to a 2!!! the RAM was the lowest on my scale, with eveything being a 3.7 or higher (besides Hard drive, which will change later when i install XP.)

what happened? it's the same ram, DDR 333 PC2700.

mabye it's a configuration thing? here's the setup:

1: 512
2: 256
--------
3: 512
4: 256

are the 2 512's & the 2 256's supposed to be together or is it bad RAM?

no silly... your mixing sticks so your system has lost its ability to interleave and run them @ spec.

For XP, always buy memory in sets of 2... nothing more. If you want 2 gigs of memory, you must buy 2 1 gig sticks and place them in the correct slots so you have the full speed of the memory + interleave.

Check your motherboard manual.. it will probably tell you what slots must NOT be populated for full support at the rated speed of the memory.

ok... i have 4 slots, right? (well right.) the 1st and 3rd slots were supposed to be filled if using 2 slots (as indicated above, my 512 sticks were doing just that). so what i get from you is that in each bank, the 512 stick is losing to the 256? then should i put them together (512's in 1 &2, and 256's in 3 &4?)

Check your motherboard manual... I think if you populate slots 2 and 4 with anything, you loose.

If you want, post a link to the manual and I will look at it.

i'm lacking a PDF reader, so it's all you, in the meatime, here i come adobe.

DL'ing now.. will post back in 1/2 hour or less

well i read it myself. didn't need to download it ya know...

Dual Channel DDR
GA-K8NF-9 supports the Dual Channel Technology. After operating the Dual Channel Technology, the
bandwidth of Memory Bus will double.
GA-K8NF-9 includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:
Channel A : DDR 1, DDR 3
Channel B : DDR 2, DDR 4
If you want to operate the Dual Channel Technology, please note the following explanations due to the
limitation of nVIDIA chipset specifications.
1. Dual channel memory cannot be used if one DDR memory module is installed.
2. If two DDR memory modules are installed (same storage capacity), one must be added to a
Channel A slot and the other in a Channel B slot in order to use dual channel memory.
You can simply install the memory modules into slots of the same color but we recommend
slotting them into DDR1 and DDR2. Dual channel memory cannot function if both DDR memory
modules are installed on the same channel.
3. If four DDR memory modules are installed, please use memory of the same storage capacity
in order to use dual channel memory and for BIOS to detect all the DDR memory modules.

well.. there you have it... also, on some motherboards populating 4 slots will force DDR to drop

You must install 4 512 modules and all of them MUST be eother double sided or single sided or you loose dual channel.


I managed to DL the manual... it does not say populating sockets will force lower DDR... you are simply dealing with mixed modules

ok... so return the 256's?

ramos

yep... I would think you are running double sided 512's in 1-3 so you need double sided 512's for 3-4

I would verify and check the memory by the numbers on the 512 sticks though to confirm DS/SS

quoi?


can you get on AIM? i can use my laptop, and we can work quicker from there.

way to leave me floating in the abyss...

anyway, yeah i took that RAM out pretty quick when my computer started constantly rebooting. thank god for laptop, RAM's out, and the computer is rebooting, and looking good.

thanks nick

oppppsss... sorry, I was working on installing a LCD projector and forgot about you.

glad you got it sorted
