Question about Biostar P4M800 Pro-M7 (P4M8PROM7) Motherboard

1 Answer

Boots, no video signal.

I attempted to upgrade my system RAM from 1gb to 2gb. In doing so, I caught a hint of a whiff of smoke/something acrid. Now, the machine boots, but the monitor is not getting a signal using either the onboard video, or the graphics card.

First try removing the memory you installed and see if it boots normally. If that does not work then try replacing the original memory with the new memory.
If the motherboard beeps at you then look up the beep code pattern in the owner's manual. If you do not get any beeps and no video output at all then it is possible the motherboard or processor was shocked. You can try testing the motherboard with another compatible processor. If that does not work then it is likely the motherboard is bad.

Hope this helps!

Did you buy a 2GB ram stick or did you buy 1GB ram X2 so in your laptop you have only 1 stick of ram in there thats 2GB or do you have 2 sticks of ram in there which are 1GB if you have 2 sticks in there means one of them dead and is not registering it on your computer if you have only 1 stick in there thats 2GB but your system only reading it as 1GB then you will need to update your bios as it could be set only to read 1GB

I recently purchased Two PNY 1Gb ram to upgrade from original 512mb. When I put both 1Gb ram in the slots, the computer will not boot up. When I take one out and put the original 512 back in with the other...


I don't know your specific model, but some of the Emachines had some memory directly on the motherboard. With the 1Gb and 512Mb sticks installed, boot the machine and report how much memory the system sees. Perhaps the onboard memory is causing you to exceed the 2Gb limit.

Please post the memory size you get here with the above sticks.

Thanks,

I added an additional 1GB of RAM card , but my computer will not recognize the additional memory. I tried swapping cards between the two slots , nothing . The specs say the motherboard can handle 1GB per...


If you have the additonal memory in the system correctly, it should be recognized.
Attempt to boot the system with just the new stick in. If it boots you most likely have a motherboard issue. If it doesn't, it's just a bad stick of memory and I suggest just getting a new one.

What type of RAM is used, and how to up grade


Hi,

The type of ram used is PC3200 DDR SDRAM. The maximum ram supported is 2GB

There are 2 slots on the motherboard each supporting 1 x 1GB (gigabyte) each.

If you want to upgrade to the maximum amount of ram then you must buy 2 x 1GB PC3200 DDR SDRAM.

To upgrade the ram take the side panel off the computer and remove the existing ram from the motherboard like in this picture.>>>

All you have to do is remove the ram and insert your new ram. Make sure that you clean the the slots of any dust as the dust can cause boot issues.


Good luck.

I have a compaq presario cq60-215dx notebook pc, was wondering how do i go about upgrading the RAM?


I have checked the Compaq Presario CQ60-215DX Specification It Originally has 2GB Memory and supports upto 4GB RAM max. If you intend to upgrade the RAM, you can buy additional RAM and put them in you system. Here is the HP Guide to Replace RAM and How to Upgrade RAM Guide
Compaq Presario CQ60-215DX has two RAM slots for DDR-2 (533 or 667) Memory Modules. First you have to check that the RAM slot is available for additional RAM. I believe that it has two modules of 1GB each in both slots. So, you have to get two modules of RAM 2GB each to upgrade to 4GB (or one 2GB RAM module to upgrade to 3GB). Hence, it is recommended that you get 2GB replacement module for each 1GB module you have on you system from local laptop repair/ service center, which would be cost effective as existing 1GB RAM Modules would be useless for you upon upgrade.

Let me know if any further clarification/ assistance is required.

Good Luck!
Appreciate generously, if the solution could have been of any help!

Just installed 2 2GB cards (Corsair VS2GB800D2) to replace the 1 1GB card in my emachines EL1200 series. Computer will not boot. replaced the old card and it booted right up.


Will it boot with only ONE of the 2GB memory-sticks installed?
Will it boot with ONE of the 2GB memory-sticks AND one of the 1GB memory-sticks?

Look closely at the 1GB memory-sticks.
Does the label show 'DDR266' or 'DDR333' or 'DDR400' or 'PC2100' or 'PC2700' or 'PC3200' ?
Do the 2GB memory-sticks have _identical_ information?
It's definitely _not_ acceptable to have "slower" RAM (smaller numbers) in the new RAM,
but it _might_ be acceptable to have "faster" RAM (larger numbers).

Just make sure it is an original ram and it must also be the right one. Of course it should boot with 2GB. Also insert the ram properply.

Trying to upgrade RAM - won't boot after new RAM installed


Install the RAM on memory slot and Switch on your system and go to BIOS settings. There you can check whether your RAM is working properly or not. If it shows no memory installed then the RAM Chip may be damaged.
