Hi,

I recently bought a 4 gb ram stick of 1600 mhz and installed it in my system (core i3,

Intel DH55pj MB, 2 gb 1333mhz) which had win ultimate 32 bits. The system successfully

booted up and showed 6 gb installed with 3.25 usable.

I tried reinstalling win ultimate 64 bit but the setup would be stuck at win logo right at start. Not knowing what to do i puulled out the 4 gb stick and successuly installed the 64bit version. My thinking was if the 32 bit picked up the extra ram so should this 64 bit one.

Unfortunately this is not working. When i install the 4 gb stick and boot, win 7 fails to start. It shows me the option of start normally or repair. When i start normally the system restarts. When i try reapair windows loading shows up and then blank screen. Whn i pull out the 4 gb stick, the system starts successfully albeit it shows 'memomry decreased, press enter to continue' message before starting windows


Intel DH55pj which officially only supports 1033 and 1333 mhz ram. Yes i know i'm an idiot but plz read this link before u call me an idiot here> infact call me anything u like just help me plz.

I can't return the ram as it is showing up fine and working and the shop will not taake it back. i've tried looking inside bios for any option that might help but cant figure anything out.

Your help will be greatly appreciated.

There is a good chance that the new ram is the issue. Windows 32 bit would see the additional RAM however it will not use that portion of the memory as the 32 bit OS will only register/address 3.5GB of ram.

What are the memory timings of the original RAM vs the new RAM?
Have you tried to boot with the new ram and use memtest+ to test the actual module? You may wish to have the test run over night.
Have you also attempted to boot the system with this new ram only with the old ram out?

Yes, i took out the 2gb stick, put in the 4 gb stick but windows won't start. i tried to boot from bootable usb to see if i can install new windows (with only the 4 gb stick inside) but the system hangs up just after loading files section when windows logo shows up.

I dont know anything abt memory timings. how can i check them??

Please keep in mind that this 4gb stick was put in computer alongwith 2 gb stick when it had 32 bit ultimate win7 . there were no problems then as it had picked the 4 gb stick as weel as the 2 gb stick. I only wanted to install 64 bit so all of it would be used. now i'm stuck with this ram i cant return :pfff:

BTW, whenever itake out or put in ram this screen briefly shows up with messages like 'table mismatch - updating remote pc assist technology setting new table fingerprint [complete]' . i took a pic of this and copied this text to share here. perhaps this might help.

As I have requested in an earlier comment, did you run memtest+ on this 4GB ram only?

Just because your system worked with 6GB of total RAM does not rule out the possibility that the 4GB ram is good or bad. Windows 32-bit will only register the first 3.5GB of ram out of 6.

thank you for your response. I tried to run memtest from a bootable usb and it started but something went wrong and pc restarted. i got scared of doing more damge and abandoned that idea. in the end i pulled out the 4 gb ram -> installed the 32 bit win 7 ultimate -> shut down PC -> installed 4 gb stick in 2nd slot -> started pc and windows started successfully. It has detected the 2nd stick and now shows "installed memory 6 GB (3.24 usable)" the same as before

I also posted the same problem to
http://www.tomshardware.com/answers/id-2030645/ram-motherboard.html
if you are interested.

I will run memtest inside windows tonight after i get home but i don't suspect a problem. it was my fault for buying that ram without reading specs and i guess i'll have to live with that.

Your system will see the 6GB of RAM however it will actually use 3.5 - 4GB of it. So in essence you really gain nothing extra. If you go to the Resource Monitor and click on the Memory tab, you will see exactly how much RAM is in use and what is available.

Guys I'm having a similar problem but with two Kingston 4gb ddr3 1333. Initially I had a 4gb and a 2gb, everything worked fine, until the 4 gb went bad. I replaced that in warranty and traded my 2 gb for 4 making in total of 8 gb. Both sticks installed and the pc won't boot. Pic works fine with a single 2 gb.
