Windows 7 64x will not boot with new ram.

[Errol500]

Hi All,

I have installed windows7 64x on a new hard drive. I still have the old hard drive with windows7 32x on the old hard drive. I installed 4 x 4gb DDR3 1333 ram sticks, along with windows7 64, these are recognised in the bios, but will not boot the system. It gets to "starting windows" and then restarts. If I put the old ram in, DDR3 1333 2x 2gb, it boots no problem.
However, when I reconnect the windows 7 32x HDD the system boots with the new 4x 4gb ram sticks....
HD55TC mobo
I5 CPU
Nvidia gtx 460 gpu

What can I do??

Run a ram check on boot. I havn't used one for a while but they are around. It might be faulty ram.
Or you could put 2 x 4gb in and see if it boots, and then try the other 2 x 4gb and see if it boots. This might tell you which ones are faulty.

I tried just 2 4gb sticks, also tried the original 2x 2gb with 2x 4gb new ones. No go.
I'll try a memory check, but if the memory was an issue surely it wouldn't work when installed during the 32x boot process? Because that seems to work fine.

Thanks for the input.

Some other things to try:

if your system will let you boot off one DIMM, try each of the 4GB DIMMs individually to try and isolate a faulty one.

Check your processor's specs as well, make sure the RAM's speed is compatible with the processor, as the memory controller is on-die.

Also check that you have unbuffered and not registered memory, usually not an issue, but mixing the two doesn't work. They are supposed to be keyed differently, but I know servers of the same gen can take both.

I'm going to give the one by one thing a go.
I still don't understand how my 32x hard drive boots fine with the ram that causes issues with the 64x hard drive. Odd.

The reason I thought it might work on the 32bit version was that it wasn't accessing the faulty ram. However that doesn't seem to be the problem.
If you have overclocked you cpu then reset bios to default.
I don't know what else you can try

What is your memory kits, MB and CPU do you have?

Tried the ram one at a time.
Got a pool header error, and a blue screens with no error that I could see.
When I stick in the old ram it boots no problem.
Its a DH55TC mobo, Asus Nvidia gtx460 graphics card, i5 cpu 650 @3.20gHz, the new ram is GVM DDR3 1333 4gb x 4 sticks (the old ram is Kingston DDR3 1333 2gb x 2 sticks)
The 64x OS still boots/runs fine on the old ram.
Just connected up the 32x HDD, with the new ram that does not boot the 64x HDD, and it boots the 32x HDD fine.
Very frustrating.

The 32x OS shows 8gb ram installed (2 sticks), and only recognises 2gb, with only 1.05gb available.
