Memory

[jsrconst]

I did a complete new install of windows 7 RC on a newly formatted drive worked fine.  After installing the first test update for windows 7 the computer would not login it would start to the login screen and when I tried to login would have an error for the following list of files; Werfault.exe, taskhost.exe, sdclt.exe, nvvsvc.exe, userinet.exe, dwm.exe 0x771a3892 referenced memory at 0x00000000 the memory could not be read. For each file the message was exactly the same. After a system restore everything was fine so a few days later I tried to install the update again and the same tine happened.  Now the computer has done this with another update and I needed to restore back in safe mode to be able to access the computer. I have done a memory test and said it was good. The memory in the computer before I upgraded was 2x1024 2x512 timings at 333 5-5-5-15 now I upgraded to 2x ocz2g8004gk 8gb timings at 400 6-6-6-18. Is this a memory problem or a windows 7 RC build 7100 problem or something else? Sometimes I have this problem after a reboot now. Computer HP Pavilion elite M9177c

Thank you

When I am having this problem of not being able to login if I shut down the computer for a few minutes and restart it will usually load for me without the memory errors.

Thank you

Most likely to be a memory problem. Start by removing and reseating the memory. Then use either whatever Win7 and HP have to test memory or a tester like memtest. If it is a fresh install from a good download, I don't think it could be the OS. Do you have the facility to easily change OS's? If so use another OS like Vista and see what happens.

I have run two different versions of memtest86+ the first 2.01 and after only one pass I had 14 memory errors all at 0000000000000 0 MB  then ran version 2.11 8 pass and no errors. Posted on their forum and the said (Errors at very low addresses are usually BIOS bugs, really the BIOS should be fixed, but since motherboard manufacturer really don't seem to care memtest now ignores these errors.)  Bios AMI 5.32 10/23/2008. Is there newer Bios, it appears this one is not compatible with Windows 7!Thank you James

OCZ RAM is junk since most require higher RAM voltage at rated speed.  Retest with the stock RAM.

I had this same problem with windows 7 RC build 7100 with the old memory that windows would start but would not log on that was why I upgraded the memory. The error was, filename.exe the instruction at 0x771a3892 referenced memory at 0x00000000 the memory could not be read. For a list of files and the first set of numbers would be the same for all files and only changed with a reboot the second set of numbers always only 0’s  two other forums have told me this is probably the bios. Just like with memtest86+ the errors where always at an address of all 0’s 0.0 MB

The memory address is given in a xy format, so its sort of row 0, column whatever the second no is (in hex). 0x00000000etc is high memory, probably BIOS in this case as that's the first thing loaded into memory.

Download Memtest.exe to test RAM in windows.  W7 is BETA.  You may need BIOS update.  Note that HP is piss-poor with new BIOS.  Therefore, you may have to live with the current condition.

Do not buy an HP if you intent to do major upgrades to the PC.

Yes the computer supports 8 MB it came with three 2x1024 2x512 I am getting the same errors with just 4 MB as I get with 8Mb. What does the address 0x0000000000 mean it is always that address on the memtest and when the OS will not load? Will try the memtest.exe you have suggested.

Thank you
