hi all ive had my motherboard over a year now and have tried to upgrade to ddr ram 4 times, when i do my computer doesnt want 2 know and i get no picture on my monitor, now the computer works fine with SDRam, is there any bios or jumpers i need to alter??

upgrading from 512mb sdram to 512ddrram pc2100,

my manuel says it will accept pc1600/2100 it is a single slot i am tryin to install!!

any help will be helpful

thanx

You did remove the SDR RAM for the attempt?

Consult your board manual. Some of those SDR/DDR boards required you to move one jumper, some had a long row of jumpers that all needed to be moved, and the rest auto-detected the RAM type. Clearing the CMOS to make BIOS revert to default settings might also be in order.

thanks for the reply, i had removed the sdr ram first, and the manuel is so usless u may aswell look at a blank page, i removed the one jumber that alters the FSB etc and differance. clearing the CMOS sounds like a good idea, how would i go about doing so??

The number 1 issue here is voltage.
SDRam = 3.3v
DDr = 2.5v
You need to be doubly sure this is autodetect by your mobo.

Number 2 issue is ram compatibility.
Your board may only boot with now obsolete PC1600/2100, or it may need a bios flash to accept later ram.

Last bios is V1.3. Check your bios boot screen to see what you're running.

hi yea ive upgraded my bios but i didnt think you could change the voltage, how do i make it autodetect is that foun in my bios screen?? or is there a jumper that will alter this aswell? do you think it may come down to having to have a new psu?? thanx again

I read your manual and it doesnt say anything about having to open or close a jumper. Make sure your installing the ram in one of the two slots on the left (the two closest to the cpu).

------

To clear your CMOS there are two solder points (#17 in diagram) that need to be connected for a short time. Unplug the computer from the wall socket, unfold a paper clip, and touch the two solder points together for a few seconds.

thanx for taking an interest, ive done this, the paperclip thing, and there is just one ddr ram installed in ddr slot 1, its fully clipped in and ready to go just wont load my monitor, seems like theres no feed going to it, but as soon as i install the sdr back in it works!!! so fustrating, thanks again

if it dosen't work on first slot try it on slot 2
make sure your memory is not defective too

Not sure if you mean you've replaced the psu, or asking if you should. If it boots with 3.3v SD, but not 2.5v DDR, it's not going to be power related.
Manual setting is via jumper,
Soft setting is via bios,
Autodetect is as it sounds: Auto. You do nothing.
For ram volt, if there's no jumper, it's auto detect, so you do nothing.
If it won't boot, it needs different brand/vintage/spec DDR ram.
(Or the ram is faulty, but it's more likely to be incompatible than faulty).
Have any of your friends got DDR you could borrow for a 5 minute boot test?

well the thing is ive tried it 4 different times all different makes, i could try that i suppose, but as its been new ddr ram every time i cant see why it wont work, no i havent replaced my psu, im just totally confused, as asrock dont want to know, thanks again
