I'd bet your mobo doesn't like the memory.
I used to like www.crucial.com for finding out what memory I could use. They do show several MSI MS-7207 models but none with the PVG suffix. Haven't used crucial in a while - dunno if their lookup tables are accurate any more.

ok it's been flashed, and all works ok, wow i didn't know it could do it via windows, althou the new start up screen looked a little different (had 2 restart) but the memory is still reading 512MB as a posed to 1GB, this is infact in Bios aswell. A couple of other things I'd suggest: 1) Go into the BIOS (usually done by hitting F8 or some other key before the Windows logo appears; it depends on your system) and ensure the RAM size is set to the right amount. Maybe it's been manually adjusted to 512MB by the system builder? 2) Download memtest86 (http://www.memtest86.com/][url=http://www.memtest86.com/]http://www.memtest86.com/[/url]), burn the ISO to a CD and boot from it. This will check to see if the RAM is bad. Let it run overnight though. It takes a while to complete. 3) If you still have no luck, get your memory from crucial.com next time. Now you have your motherboard make/model, their website will probably tell you exactly which RAM you need if you enter the details. _____________________

Oh look, you beat me to it. I bought some a couple of months ago for a very recent laptop, and they appear to be as good as ever. =)Good to know they're still active. All the numbers and codes and crap can be pretty mind-numbing, even to geeky types - they have a nice interface to help you figure out what's right for your system and, last time I used them, pretty decent prices. I still think he got the wrong type of memory.. Like, maybe it's DDR memory and the mobo only knows SDR (or quadpump/DDR or whatever) so it's only seeing 1/2 the bits.. Chaos, head over to crucial.com and do their system scan stuff. That should give you a decent idea of what you should have in there. Also, if you can post the make/model of the memory you got, that'd probably be helpful.. _____________________

My gut feeling on this is that his 512mb memory sticks are not compatible with his 1gb memory sticks and they should be immediately removed from the system to see if the system recognizes the 1gb sticks. If not, the 1gb should be removed and the 512s reinserted because the 1gb are probably the wrong type.

He's tried just the 1gb and didn't help.. he probably just bought something not compatible.. iono... I don't feel llike researching the specs he listed above _____________________

Check to make sure that you are inserting your RAM modules in the appropriate banks.
IE: All 512MB sticks in bank A and all 1GB sticks in bank B. Mixing and matching usually disables RAM module's internal bank interleaving, possibly leaving you with merely 512K of system RAM. This board seems to support Dual Channel DDR memory configurations. I found a handy chart for what I believe is your motherboard here: http://www.msicomputer.com/product/p_spec.asp?model=K8NGM2-NBP&class=mb There are 6 boards bearing your model number and several sub-revisions. I took an educated stab at it. But to wit, *MOST* Dual channel DDR boards will break the sockets into a set of banks. A pair of a certain colored sockets make up one bank, the other color the other/secondary bank. Inserting mis-matched pairs of RAM at random in the sockets usually creates a no-POST situation. Yours must be a failsafe and or fail over protected system where it locks all sockets out but one standard, easily timed stick of memory and will boot off of that in an emergency. Lucky you! *giggle* But yeah, stick all of your new RAM in the GREEN sockets, old into the PURPLE and see what that gets you. EDIT: Final thoughts. |

What is the exact name and identifying numbers for the memory chips?
Can you provide pictures of the memory chips? _____________________

your motherboard could be fine and whoever you bought the ram from gave you 512mb sticks instead of 1gb sticks

ah its ok i did a bios check. the motherboard is MSI MS-7207PVG You can also use CPU-Z to help identify computer hardware. Located here http://www.cpuid.com/ As per searching http://www.msicomputer.com/index2.asp with your model number it keeps saying "Product does not exist". Searching for "MS-7207" it has a few returns based on CPU. I would assume it's a AMD cpu? Look at all the search results and try to identify your board from the pictures and specs. I would suggest you first take out the old ram like others have said, place the new 1GB chips in slots 1 & 2. See how it works form there. If they still read as 512's use cpu-z and check the memory tab and see what the specs say. At the MSI site you will get info on flashing your BIOS, just make sure to read the directions and follow them correctly as your could easily brick it. |
