Windows 7: Windows boot issue after installing additional Memory

Windows boot issue after installing additional Memory

Hi Team,
I have a custom built desktop system currently running on i3 Processor with Intel® Desktop Board DH55TC and 2 X 2GB DDR 1333 RAMs. I was earlier using Windows 7 Ultimate 32 bit OS but planned to upgrade the same to 64 bit OS. Along with this i also upgraded the Memory and purchased an additional 4GB DDR 1333 RAM module. I installed the new memory and the system detected it in BIOS and in the OS also till it was 32 bit OS. I then tried installing 64 OS and it would not let me do it and kept restarting. Then i just used the old memory cards and installed 64 bit OS, then installed the new Memory and it would again have the same issue. Motherboard has 4 mem slots and currently i have only populated 3 of them, is that the issue ?? Or is some kind of known issue with OS ?? Or somthing to do with Memory Voltage ??

Sounds like one or both of the new memory modules is defective. Return for a replacement.

Have you tried running with just the two new modules?

Thankx for the reply, but i only purchased 1 new 4GB card. I already got it replaced once thinking that it might have been the card but that did not help :-(.

According to Crucial Home Page | United States (USD) that motherboard takes DDR3 memory, not the older DDR. Their current offering is DDR3 PC3-12800. It uses 2 banks of 2 modules [or 4 modules] for a maximum of 16GB.

Just a note, there can be problems using non-matched modules and sometimes not using in matched pairs.

Try just using the new stick you bought to see if it works by itself.

That will rule out if it`s a bad stick, but I would think it`s fine.

If Berton`s findings are correct, then ideally you would want 2 x 4GB sticks of DDR3 PC3-12800. 8 GB total is plenty.

If you can afford more then get 4 x 4 GB sticks, or 2 x 8 GB sticks.

2 sticks are easier on the memory controller of the cpu then 4 sticks :)

And always buy your memory sticks in a 2 pack or 4 pack.

I recommend Corsair Vengeance or GSkill Trident X.

G.SKILL - World's best performance DDR3 memory for desktop PCs, laptops, Macs & high speed SD flash memory cards.

Please post the exact i3 model.

Thankx AddRAM, but i did try with just the new card and the funny thing with that was that it does not get me to boot to OS. It is getting detected fine in BIOS and the system does complete POST but as soon as it tried to load to OS it fails and keeps restarting. So i also think that either it has something to do with pairing or memory modules or some issue with drivers. Not sure though. I can buy another stick and pair it along but my concern is that if that too does not work for some reason than i am left with 2 new 4GB sticks

Does it work if you do not out have any of the new memory in. If yes then return the new memory for a replacement as some of it is defective.

Did you run the Crucial System Scanner software to find out what type of memory is in your computer?

That's always the first step, and then confirm it via google by comparing your model PC or mobo + RAM Upgrade. I don't buy until I know beyond doubt it's the precise replacement.
