Mothorboard and RAM compatability

by alixjames / June 16, 2007 2:37 AM 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


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 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

Thanks Bob for your help - my computer is only running 1 stick at the moment 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
by alixjames / June 16, 2007 6:06 AM PDT
In reply to: If this was mine...

I just read around on a few sites and it seems that dual channel might not be available to 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.

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

You mean the motherboard does have dual channel support?

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

Last question..honestly!
by alixjames / June 16, 2007 6:32 AM PDT

Before I call it a day..if I'm changing 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!

I've done this but...
by R. Proffitt Forum moderator / June 16, 2007 6:45 AM 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.

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.)

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!

In reply to: Just Curious...

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.

In reply to: running 256mb!

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 it happens it doesnt really.

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. :P)

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

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...

In reply to: :)

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.

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 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.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
