Win7 won't boot after Upgrade with 2*4Gig DDR3 RAM (GA-H55M-)

[mde..]

Hi Guys,

Not sure if anyone can help but I'm having problems upgrading the memory on my GIGABYTE system. When I google the symptoms I seem to get 1000's of hits but cant find any sensible solution.



SYMPTOMS
Memory detected at BIOS level by motherboard (GA-H55M-)
Win7 splash screen appears but hangs and fails to boot unless I return my old memory and remove Corsair memory.
Corsair memory is Corsair Vengeance, 2*4Gig, DDR3, 1.50v, 1600mhz
OS is Win7 64bit Home Premium (so should support up to 16Gig)

STEPS TAKEN SO FAR:
I have removed my current 4Gig memory and replaced with 2*4GB Corsair Vengeance DDR3 1600mhz memory.

According to GIGABYTE website this memory is correct for my motherboard I have checked specifications. The motherboard can support from 800mhz up to 2200mhz (including 1600mhz DDR3 memory) and can support up to 16Gig.

The Operating system should support up to 16Gig (again checked Microsoft website for memory support on Win7 64 Bit home premium).

MSconfig has been checked and I confirm that I have UN-ticked the box to limit memory under the OS.

Make sure to take any overclock off and when you start hit delete key and the load optimized defaults and see if it will start that way.

Hi thanks for the reply.

Just set bios to optimised default, also tried the other default setting (think it was called load safe) but still have the same problem.

OK, after enabling XMP I now have the memory running at 1600mhz. Initially I could still not boot but when I go to msconfig and set the Max memory manually to 8192 the system boot up.

8Gb is displayed under My Computer but only 3.3GB usable??

Do you have windows 7 32bit? If so that is all it will see if you use windows 7 64 bit it will see it all. One day long ago I think there was an updates for windows 7 to see more ram but im not sure. I was working on someone else's computer and cant remember if I got it to show or installed windows 7 64bit has been to long ago for me.

Hi,

no its Win7 64 bit Home Premium (which can support upto 16 Gig).
