System won'n boot if i installed two RAMs

try upgrading your cpu my just kill the motherboard

First of all you want to reset your BIOS. Instructions on how to do this can be found in the manual which is provided in the following link, the manual calls it "Clear RTC RAM" which is on page 35. While you are inside the computer, make sure all cables/connections are firmly seated.

If this fails to clear up your boot issue, you need to go a little further into the computer. Make sure your computer is off and unplugged from the wall before continuing.

Next you need to remove ANY hardware that is not needed to boot. This means any add-on cards (expansion cards), hard drive, RAM, video card, CD/DVD drive, USB devices, firewire devices, speakers/microphones, keyboard and mouse.

After they are all disconnected, try booting. If it acts the exact same as it did before, you have to go further into the computer again. If it does something different, one of the components you removed was causing your boot problem. Replace them one by one, trying to boot between each component you hooked back up, I would first start with the RAM.

But, if the computer still does nothing upon boot, you need to bench test it. This means you remove the motherboard from the case and set it on a hard non-conductive surface (kitchen table or a work bench). Then you hook up the Power Supply correctly and attempt another boot. If now you hear beeps from the motherboard, your motherboard had somehow shorted to your computer case.

If you still get no beeps, your problem is either the motherboard or your CPU (processor). To narrow it down between those two, put your processor in another computer to see if it works.

If you go through all of those steps and get nothing, I would be looking mostly at the motherboard.

Hope this helps.

with rams, if the memory it has is higher than that of your cpu, the pc will not boot up or if it is too low compared to your cpu again.

thus, you say it has got two slots right, remove both of the 512's and insert the 1gig only, run your computer, i am sure it will boot up nicely. switch it off. put one 512, if it does not boot then you should know that your ram has an excess of memory that your cpu could not apprehend to.

post a coment if this does not work.

thanks,

wonder

you can only expand to 2 gb think you have extended toomuch

You just need to upgrade the RAM to 1 GB or higher there is no problem with the motherboard.

Hi araw,
Sorry but the Asus P5RD1-VM MB does not support any dual core CPU. Here is the Asus link showing supported CPU's.

Here is the link for all driver software & manual.

The ASUS P5RD1-VM takes the PC2700/3200 DDR SDRAM DIMMs. You can upgrade your ASUS P5RD1-VM to up to a maximum of 2.0 GB Memory, the system has 2 sockets to install Memory. For best system performance use the maximum amount of allowed Memory per slot for your system i.e. 1 GB.

Thanks

More people should complain with Asus support. Checking Asus forums, you'll find there's an obvious problem with a PCI-E video addon + 2 used memory slots. In my case, I had 2Gb (1 + 1), mb with bios version 1104, and it worked fine; when I installed a new PCI-E card, the system was very... very sluggish. Now I have uninstalled 1 memory, I'm using only 1Gb of RAM with the PCI-E card, and it's working well.

Again: checking Asus forum, this is a reported problem, and a bios bug... Asus should release a new bios version, but they seem not to bother, as this is a relatively "old' mb...

go to bois set memory to table defult i thikl it may solve the problem in xp the memory is shared with the graphics card i had the same problem i just did correct the memory in bois all went up well

The manual is here: http://dlsvr03.asus.com/pub/ASUS/mb/socket775/P5RD1-VM/e2440_p5rd1-vm.pdf (very slow download). Look under Advanced/Southbridge/SATA
