Things causing the problem, the pc is old and wont handle that much memory or wrong type of memory, or while installing it it probable faulted out due to improper grounding and will need replaced. try swaping slots for the sticks and see what happens. or put one stick in one slot, start the pc if it works, shut down pull the memory out and pput it in the other slot and start pc, if it works try same thing with the other stick....if not its the port for the memory.

My e machine desktop model w3503 is using only 368 of ram out 512MB why

Don't go by what you see in windows as far as the memory that is being used. Go into the BIOS of yoru emachine and in the BIOS it will tell you how much memory is in your system. As long as the total memory in there is 512mb, that is what matters. Windows doesn't always give accurate info but the BIOS will.

If the BIOS doesn't show the full 512 then its either a memory stick problem or a motherboard issue and you won't truly know for sure until you try other memory sticks.

It you removed the 1- 512 memory did you go to only the bois or did you try to let it boot? if you did not try it with the first stick of memory in and see if it works, if it does not put that stick back in and remove the second one. just because it shows the memory does not mean the memory is bad.

Memory won't add on a Gigabyte GA-6VEML

this will be dependant on the bios version. or if the 2 ram modules are identical or not. if they,re a matched pair. the motherboard may not like or run in dual-channel mode. sometimes adjustable in the systems bios. the other suggestion, is to try 1 stick of ram, in each slot individually. This will eliminate A Faulty Slot. Failing any Of The Above. try 2 x 256mb sticks, And Obtain The Latest Bios Update from The Manufacturers Website.

Dell Dimension 4600 desktop memory upgrade

well first the mother board needs to be capable of handleing that much memory you can check that by going to the dell website and checking the specs on that model pc or mother board if the bios isn't recognizing it the chances are it won't but take out the 512 stick and just try one of the 1Gig if it does recognize that then try the second stick if it doesn't recognize them both then chances are it can't handle that much memory.

Adding ram do I need BIOS update see detailed question

I don't think that this will work! I think 512 is the maximum for it. May be it'll just improve speed a little but it's always risky to update BIOS on older PCs. And this 512 sticks will cost you a lot. I think you better think to buy a new PC. Good Luck!

Memory Problems (MSI KM4M-V Motherboard)

if you know the make and model number of the memory sticks you will need to contact the manufacturer to find the voltage specifications so you can adjust the bios accordingly. Or do a google search with the model number and make of the memory stick for voltage details

Sorry for the delay in my response.

Your computer will accept a maximum of 1 GB of memory. If both memory modules are the same brand and part number then it is possible that one of the sticks are bad.

Try each 512 MB memory stick in the first memory slot, without installing a second stick. This will troubleshoot to find out if one of the 512 memory sticks are bad. If both check out ok, then the problem is with the video adaptor.

Have you tried adjusting the refresh rate on the monitor as I described in my first response?

My final possible solution would be to upgrade the bios. Below is a link to the webpage for your computer system. You will find links for troubleshooting guides, driver and software downloads, product specifications, etc. If you click on driver downloads, then choose your operating system, you will be directed to a page that should provide the latest ROM (bios) update.

Upgrade from 512MB to 1GB

The specs on the memory are correct, so you purchased the correct type of memory for this motherboard. If your getting no video when you power on with the 1gb stick, I would be willing to bet the 1gb stick is bad. Can you return it and try another stick?

Dual chanel problem

The beeps your hearing are known as bios beeps. They are telling you there is a problem with your memory. On your board the four dimm slots are split into two groups. A & B. Pg. 19 of your manual. Please read Pg. 21. Remove all your memory & put only two of your 512 Dimms into slot 1 & slot 3. Boot the Pc. Notice any beeps? Check your boot screen to see if bios sees the current memory as matched memory. Shut the Pc down & remove memory, replace with the other 2 Dimms in the same slots. Boot Pc. Again check to see if memory is being seen as matched memory & no beeps. Are you getting the idea here. What we are doing is trying to find which if any dimms may have a problem & which dimms work in which channel. Increase in size to 3 dimms or 1.5Gb in memory till you find a working order with no beeps. If you think 1 or more dimms may be faulty download a free test program called -Memtest86 at this link. Scroll down till you see - ** Memtest86+ V1.70 (01/14/2007) ** all typed in red. Here you can choose what type of bootable file you want. An iso or a zip. You can creat a bootable floppy or a bootable CD.
This should help. If you have trouble & need more information please post back.

Memory upgrade problems

Hmm if the pc takes DDR Ram , it should deffently take 512 sticks, have u tried booting the computer with just the one 512 stick ? or try putting the 256 stick in and 1 x 512 stick , test it that way with both sticks , some older computers there is a bios setting for upgrading to higher amount of memory, but in your case with DDR ram i dont think so , i mean it may be worth a shot going into bio's and load optimized defaults , press f10 to save settings, try one stick at a time after that , if still no go , there is a jumper pin on the mother board that u can move over a slot which will restet the bios, if u dont know this jumper pin or where it is, just remove the round battery on the motherboard for 30 seconds , then put it back in , try your new ram then , u will be asked to save settings on boot up , if it still dosent work the ram is either faulty or incompatible, alot of the time with Dell , HP /Compaq desktops there fussy with the type of ram they take, but if u ordered from dell it should have worked !! whats the brand name of the ram u have is it hynix? /HP this brand of ram has alot of issues with compatibility,
