Mothorboard and RAM compatability

Jun 16, 2007 2:37AM PDT

I have a Medion PC - mothorboard is MS-7042 - online checks say I have RAM slots but actually have 2. DDR dimm PC3200 256mb in there at the moment. Bought this...

1 x DIMM 1GB DDR 400MHz, PC3200, 2.5V, Non-Parity, Non-ECC, Unbuffered, 184-pin

DUAL IN-LINE MEMORY 128 X 64, 16 chips, HIGH DENSITY

Manufacturer: NCP
Module no: NCPD7AUD0-50M8A NC 02061

Fits in the slot ok although it is shorter in height once installed that the existing 256mb RAM. I put this down to being newer technology hence they made it smaller.

When I run the PC with the new memory in it just goes to a error screen asking for safemode or windows normally amongst other things..whatever I click it just restarts the computer..cant get into Windows. Have tried the 1gb in both slots alone and with the 256mb...no joy. Any reasons why?

Surley if I have bought DDR DIMM pc3200 400mhz then it should be ok??

Appreciate any help, reagrds, Alix

Just looked at the manual and you won't be happy.

It's likely you will lose your DUAL CHANNEL RAM feature by sticking in a single stick of ram. I won't answer what DUAL CHANNEL is since you can google that but the speed loss may make your next question be "Why is my machine slower with more RAM?"

I'd look to getting a pair of memory sticks.

Since you only have 2 slots, I'd get such in pairs at the SAME time. Mixing sticks may not work for DUAL CHANNEL operation.

only 1 dimm in from purchase
Jun 16, 2007 4:12AM PDT

Thanks Bob for your help - my computer is only running 1 stick at the moment anyway..it only had a 256mb dimm from purchase.

I will try the method suggested in the 2nd post, thanks.

If this was mine...

I'd get a pair of 512MB's and let the DUAL CHANNEL speed kick in.

I might look at doing this..

If this option is going to be faster I might go for this instead of the 1gb option. Thanks for the heads up

Maybe dual channel not available
Jun 16, 2007 6:06AM PDT

I just read around on a few sites and it seems that dual channel might not be available to me...as I think the 128*4 memory is dual channel....the 64*8 that I need isnt so I can make out. so would this mean my best option is to just put as much is as possible?

Only one item for me to write yes or no.
Jun 16, 2007 6:10AM PDT

I found the motherboard manual so it all depends on the CPU now. Almost any Pentium 4 should kick it into gear.

P4?
Jun 16, 2007 6:15AM PDT

You mean the motherboard does have dual channel support?

Im only running a Celeron 2.8ghz on it at the moment :s

You can see it in the manual or...

Last question..honestly!
Jun 16, 2007 6:32AM PDT

Before I call it a day..if I'm changing processor...am I able to just swap them and everything will be fine..plug and play so to speak. Or do I have to change heatsinks/fans etc.

Thanks for all your help guys on here...priceless!

- Collapse -
I've done this but...
Jun 16, 2007 6:45AM PDT

I always fit a new heatsink and fan since 99% of the time the old pair is often the wrong size for the job and the fan has about the feeling of an 120 thousand mile Chevy.

suggestion
Jun 16, 2007 3:09AM PDT

ddr400 is compatible with your motherboard. remove the old 256mb and try putting the 1gb in dimm slot 1 (slot furthest from cpu). make sure the slot is clean and dust free. start the pc, enter your bios, and choose fail safe defaults. (i found your mobo manual at the link below, but it doesn't have any bios reference so i can't tell you specifically how to use the fail safe defaults.)

Just Curious...
Jun 16, 2007 4:28AM PDT

I'm just curous, but why sould he go from 512 Meg to 1 Gig? If you installed a New program like "Quickbooks" for Example, it may have cuased a problem when he changed from 512 to 1,000 Meg. It happened on my computer, but it could also be as simple as what "Ramarc" Suggested. Tell us if it didn't work though.

running 256mb!
Jun 16, 2007 4:35AM PDT

Hi guys, im running 256mb at the moment. It was unclear in my first post...I said I had 2 dimm slots...not 4 like I had been told when doing an online check. Then I went on to say I had a 256mb dimm installed. Im currently looking through the manual for the motherboard online and then going to try find out how to access the bios.

What do you mean...
Jun 16, 2007 4:40AM PDT

What do you mean looking for the "Motherboard" "Online"? Do you mean that you don't know what it looks like? (Too bad I never finished my computer class, we were going through how to mantinence your CU. T_T)

Yeh Ive had the case off and know what it looks like I was just checking to see if the manual (as I dont have a paper copy) tells me anything about the memory that I am missing...as it happens it doesnt really.

I wouldn't Expect...
Jun 16, 2007 4:54AM PDT

Yeah, I wouldn't expect the Manual to tell you what would happen if you changed volume of your "Random Access Memory".

(I meant to type "CPU" in my last post. Silly)

solution possibly?
Jun 16, 2007 5:02AM PDT

apparently I need 64x8 not 128x4

What do you mean "Apparently"? Did you find that in the Manual or did somebody tell you that?

Jun 16, 2007 5:15AM PDT

Ive just been told by someone who sells memory. I wasnt aware of this before I bought it so clearly I have bought the wrong thing. There was no reference to this in the motherboard manual either but its the only explaination I have really.

Be careful...
Jun 16, 2007 5:21AM PDT

Tell me what company this is, a lot of people like to rip you off when it comes to this stuff. It's a complicated field and people usually listen to them because you're going rto spend $500 and have the wrong thing somehow or you need something else. Just ask a lot of question and you'll be fine.

Not sure...
Jun 16, 2007 5:38AM PDT

The First one looks a bit better because you should be able to track it by that code on it, but I'm not sure. The second one was used I think, but I can't tell.

They are BOTH "1 Gig DDR" 1 RAM PC 3200" but they are difrent designs themselves. They both should work for your PC, but I Don't have a U.K. computer like yours.

thanks
Jun 16, 2007 5:51AM PDT

Thanks for all the help with this..I will look into it and hopefully get something working. The 1gb I bought and the original 256mb are bother DDR pc3200 400mhz dimms so it confusing. I guess it is down to the 64*8 thing or something about high density and low density.
