Question about MSI MBOX P4MAM-V (MBOXP4MAMV) Barebone

3 Answers

Memory types My P4Mam MS-6787 M-ATX Mainboard runs ok on one stick of DDR 400 Ram. As soon as I try and plug another 512 stick in the same (DDR 400) it will not boot correcectly and comes up with all sorts of errors. Sometimes it will start Xp ok but bomb's out during an operation.sometime says it needs to do a 'repair' on Xp. The book does say uses DDR 200 and DDR 266 so I suppose I should only use that type??? But why does it go ok on one 512 of DDR 400 ? In either slot too, doesn't matter which. Both sticks I have run ok on their own so neither are faulty. Would just one stick of DDR 400 in the 1 gig size work ok?

Never use a memostick who arent suported my the MoBo. In your case you sould use 266 sticks and nothing else. The reason why the book says "Use 266" is because the bus is only suport that speed. Using 400 sticks dosent give you that advantage coz your MoBo automatycli take the 400 down to 266. If you putting in more 400 sticks You can damage your MoBo. Your MoBo arent capeble to handle all that. So if you want a stable PC ALWAYS use the recomended momosticks. I shure that you will have even more truble by putting in 1gb of 400 sticks.

Good luck

My MSI computer won't startup. It has an

It appears that you have only checked the power supply and the on/off button. There are many reasons a computer won't start.
These are only two. Have you "stripped down" the system? This means removing everything but the CPU, Memory, and video card. If it starts with only these things attached, then you can rule out the mainboard, memory, and video.
Next remove the memory. If it starts but you get memory error beeps, then it could be one of the memory modules.
After all that, you can then figure it's the mainboard or the CPU.
As for circuit diagram, I would think these would be very hard to find.

I am wanting to upgrade the ram on my mothers computer. She has a Phillips Intel pentium 4, cpu 3.06GHz. Can anyone tell me what type of ram and how much it will hold?

Access the Phillips web-site, and do a search, based on the model-number, to see what type of RAM (DDR, DDR2, DDR3) is supported, and what the largest size per stick of RAM that the motherboard supports, and to see how many slots for RAM exist on the motherboard.
Open the case, to count the number of installed sticks of RAM,
and to count the number of empty slots for RAM.

Or, just take the computer to any computer-store, and have them open it up, do the counting, and do the research on your behalf. Then, buy the RAM from them, and they will install it, usually for free.

I have a k9n4 sli motherboard with 4 places to put 2 gb strips of memory. i have 2 of them installed and working but cant get the other 2 to work what am i doing wrong?

A number of things could be happening.

Correct memory type?

The mainboard provides four 240-pin 1.8 volt non-ECC DDRII DIMMs.

DDRII modules are not interchangeable with DDR and the DDRII standard is not backwards compatible. You should always install DDRII memory modules in the DDRII DIMMs and DDR memory modules in the DDR DIMMs.
- In dual-channel mode, make sure that you install memory modules of the same type and density in different channel DDR DIMMs.

For more information on compatible components, please visit

Here's a link to a manual for your motherboard:

Installed new ram-went from 2 512 sticks to 2 1g sticks, the comp wont boot, only the fans come on, no lights on the power button or signal to the monitor. I put the old ram back in to see if it would...

dose the ram have mem chips on both sides of the ram stick, sometimes this causes the problems, i would sugest that you clear the Cmos, maybe take out the bios batterie and leave it unplugged for couple of hours, plug it back in and see if the old ram works ok, if it dose then maybe try the new ram maybe one stick at first.
good luck.

Comp won't boot after installing new ram. possible motherboard problem?

try emoveing both sticks and blowing into the ram slots then replace 1 stick at a time. if this dose not work try checking all the cables to make sure nothing got knocked out of place when you installed the memory in the first place. (bleeping sounds can mean a lot of diffrent things if the problem carrys on count the bleeps and look on google to see what that number of bleeps means for your motherboard) hope this helps

Barebones troubleshooting

Lex -

I would first check your ram, make sure its the right type and rating for the motherboard. Although most systems will beep at post for a memory issue, sometimes reseating the memory alone can clear up a startup hang.

If the memory is seated okay, the right type and speed rating, try using a different video card in the system. Its possible that the system is starting up normally, but not being displayed.

If neither of those help, minimize the system. Plug in just the bare minimum needed for operation - Power supply, processor, heat sink & fan, a single memory stick, a single hard drive, video card(if its not integrated on the motherboard). Plug in a monitor and the power cord, then see if the system boots.

If all that still fails, verify that the CPU fan AND the Power Supply fan are spinning when power is on. If so, this points to either a bad memory stick(try another), bad processor(if available, try one at a slower or faster speed), or bad motherboard.

Hope this helps!

Your laptop can have up to 1 GB of memory. You should have two slots and you can install 512 MB per slot. Your laptop is using 200 Pin DDR PC2100 266 MHz CL 2.5 SODIMM. You can also install PC3200, but your laptop will clock it down to 266 MHz.

No boot - constant fan

Update from my immediate post today: I've looked at other post that is suggesting memory or battery problem. To my surprise, after removing one memory from bank2 of DIMM, the PC came back to life! Whenever the second bank has either memory stick in it, it will stuck. So I ends up with half the memory, but get my system back. Not sure how long this will last though.

I Had similar history as the initial post: runs OK, and started random shut down 2 days before final stall. I am putting back my HDD and system, should be working, for now at least.

Change RAM

If you put the original RAM back in (both sticks) does the system boot?
