I can install Windows 7 x86, but not Windows 7 x64, get BSOD MEMORY_MANAG..

By fmuise ·
I am currently at a co-op at an IT outsourcing company, and I was instructed to install Windows 7 x64 on 5 systems through WDS. The first 4 went fine now on the fifth, I am getting a BSOD while the PE loads up. STOP 0x0000001A (0x0000000000041284, 0xFFFFF8A0004D7001, 0x0000000000000,0 xFFFFF781C0000000)

These computers only have 1GB of RAM, I found out after that you need minimum of 1 GB for 7 64x but the others worked fine. The diffrence between the computers are one in a Optiplex gx520(which worked), and one that is a Optiplex gx620 (which didn't work). Not much diffrence between the two besides the Processors, one its both pentium D, ones a 830 3.0Ghz and other is 945Ghz. Any ideas??

I dont know if your doing the same thing I do but I know a lot of times depending on your hardware setup and which OS you are trying to install you might want to look how your SATA operations are set, raid/achi/ata ect...change those and you should have some luck.

Well as these systems share a common BIOS

I would assume that they run on the same or a very similar M'Board. So look at how much RAM is set aside to use a Video Memory which may be tip[ping one over the lower edge to install 7 64 Bit to.

You may also need to test with the Windows 7 Upgrade Adviser to make sure that the hardware fitted to the one that doesn't load is 7 64 Bit Compatible.

The only real difference appears to be the Video Cards here so I would be looking closely at those. You may need to enter the BIOS and lower the amount of RAM set aside for Video RAM or Shared RAM or just fit a suitable Video Card.

I would also test the RAM with some RAM Test Tool as different RAM Makers may have different amounts of Actual Physical RAM on the Module and one may just be too small for the OS that you want to install. You may need to upgrade the amount of fitted RAM to get this to work part way decently. But even if you could load 7 here it's going to be a painful experience for the user.
