Changed RAM on P4M800PRO-M478, didn't work, changed back, won't work

Hi,
Heeeelp. I'm trying to help a friend by seemingly doing the simple thing of installing RAM. The motherboard is a ECS P4M800PRO-M478, and it is supposed to take DDR2 533mHz. He bought some 2Gb, and I tried to install it, but the computer wouldn't boot at all. (Ok, at first I left in the old DDR RAM, but it didn't change when I took the old RAM out). The computer didn't seem to find the hard drive at boot up. It doesn't beep, it just checks the media drives.

Then I read about this mobo, and realized it has problems. There were a couple of people who suggested upgrading the BIOS, so I went to ECS's website and successfully did the procedure to flash the mobo with the latest BIOS. The computer booted back up after I entered the date/time. Then I tried again to change the RAM to the new DDR2 memory, and no change happened. Then I tried to go back to the old DDR memory, and now it won't boot up at all.

Any help greatly appreciated. I have to leave town, and I need to at least give him his computer back in working condition.

    Hi,

    thx for asking. it doesn't post at all (i think that "post" is the right term...i'm a bit green) it doesn't beep or show me a BIOS screen, in fact the screen gets no signal at all. I can open the media drives.

    Reading the manual which I only found afterwards (duh!), I think that for DDR2's it can only take up to 1Gb...or is that b/c it's an old board that the manual says that (ie b/c no 2gb modules back then)?

    Oops, I forgot to say in my reply ot colliewob that the strange thing is that now it won't post w/ the old memory module in either. Just like when I put the new memory in. Could I have killed the old memory module, like by taking it out and putting it in too much?

    Immediately after the BIOS upgrade, I had no trouble booting up w/ the old memory inside.

    Thanks for the suggestions Colliewob. Unfortunately, I had to leave town before I got a chance to try it. So I can't update you on what happened. I think my friend took it in to one of his friends with a computer shop, so I'll try to update you on the outcome. I guess I learned also not to start ******* around with computers just before I move cities.

    It's too bad, b/c I actually like learning by troubleshooting. But this has given me new motivation to finally learn how to build my own machine.

Is there anywhere in BIOS to check RAM settings

    Seem strange but try this remove everything from M/board except for memory (OLD ) and video card that is hard drives CD DVD modem and whatever and try to boot You could have something on board that is causing trouble if you start from basic and it posts it mean one of the addons is causing problems retry with one at a time fitted
    If it boots with minimal vid and mem in go to BIOS and set to default
    If does not boot then card probably faulty Sorry

When I upgrade P4M800PRO-M478 motherboard with 2x Kingston ValueRAM - Mémoire RAM - 1 Go - DIMM 240 broches - DDR II it doesn't recognize it as 1Go memory but only as 512Mb!! What is wrong??


hello nepr29

my name is ausi

i had a look at your main board. it is capable of 2gig RAM (maximum). you issue is typically related to the type of
RAM you are using. your posting does not indicate the RAM model.

you have to make sure the
RAM you are using is double sided (has chips on boat sides of it). older mother boards have problem addressing the full capacity of single sided RAM, so it reads only half of it.

good luck.
if this was helpful please vote for me.

ib_ba_87,

Since your using P4M800PRO-M478, I recommend you to read the manual to refer about the pinouts for all the connectors for your motherboard.

Just in case you don't have the manual, here the link for you to download.

Don't forget to rate my solution, thanks!!

P4M800PRO-M478 doesn't function


I had told you I changed one Fet that positively had burned. I placed a IRFZ48N, a more powerfull transistor, unecessary of couse but the only I had in my old things. But the board doesn't function and so I searched for more damages and yesterday I found two resistances of 0 ohms opened. I changed its by a jumper and power on the MB. Today it is running with a Pentium 4 2Ghz, the OS Windows XP SP2.
