Hi all, I carried out a simple memory upgrade but when I switched on I get no POST and the CPU fan doesn't spin up. I have a Gigabyte GA-K8VM800MNF mobo which supports 2Gb of RAM in two 1Gb slots. I have put 1Gb in one slot and left 256Mb in the other and all is Ok, but a 1Gb in both slots is a non starter. I cannot find anything on the mobo site to say anything other than 2Gb should be fine.....grrrr

Just very frustrated, and not being super clued up on computers I thought I'd try in here for some much needed help.

Any help will be very much appreicated.

Cheers

I think I may have found the issue. I understand there may be a problem with my mobo/cpu not supporting more than one double sided DIMM. This coud be why it works fine with the 1Gb (double sided) and the 256 Mb (single sided) and not both 1Gb Dimms. I understand that if 2 double sided DIMMs are used then it must slow down to a 333 Mhz clock speed or something. I have looked at the BIOS settings and there is no method of changing the clock speed....I have trawled the internet for a flash or something that will allow me to do this.

Ok, cheaper to get a mobo that will allow me to use 2 x double sided DIMMs or by a single sided 1Gb dimm (if they exist)....

Please help.....I'm in the dog house already cos I've spend all day trying to sort this...

While the RAM issue may be correct... I have never heard of it.
Have you tried Gig support?
They have an activeX scanner that will ID what Bios/ drivers you need
Or you could do it manually.
I searched for that board and got about 20 revisions-- so you need to find out exactly what you have there.

GIGABYTE - Support - Motherboard - Download Center

Hi, and thanks for the reply.

I have tried the Giga-byte download centre but cannot use it, I press the "GO" button and it comes up "now supporting K7 blah blah", press "OK" and nothing, just "done" with yellow warning triangle bottom left of the window.

I have downloaded Bios@ which tells me that my bios is up to date.

I'm running vista Ultimate.

The yellow warning triangle indicates a script error-- I am not all that used to Vista yet.... built in popup blocker ? In order to make that scanner run you would have to disable it.

IE7/tools/first menu item/select disable... it would make things easier-- there are other drivers that may need update (like chipset). I would temporarily disable your AV/firewall, also during scan... should only take a minute or 2

ok, done the scan and all it comes up with is an on board LAN card update. Where did you find these 20 updates. Gigabyte support siad i need to be sure I'm up to F8. Doing some more digging, the baord may be a bali (in a OEM packard bell machine) with the same board number. Confusing or what. Anyhow on normal POST, I can see:

Award Medallion Bios V6.00PG
K8VM800M-NF 1.0X

(then at bottom of screen)

11/06/2005 - K8VM800-8237-6A7LK03C-00

Does that help in any way?

Cheers
