Hello,

I bought an AD-02u in June 2011 and it has been a mostly decent PC, but every few days, it blue
screens with an almost different error every time.

I tried running MemTest 86 on it and sometimes it comes up with a few errors and sometimes it
will run for 24+ hours with 0 errors.

Im thinking it may be bad RAM, but wait! There's more!

I purchased 2x 4GB A-Data sticks that the Tested Memory List said were compatible (the bottom
line from here): http://downloads.zot...mb/cpu/a183.txt

I then noticed that the list says the memory is tested at 1066, not 1333, so I go into the BIOS, and
sure enough, it says its running at 1333, not 1066. The problem is, there doesnt appear to be ANY
WAY to drop the RAM frequency from 1333 to 1066. How did Zotac test the RAM in this model at
1066? My BIOS (v2k120220) doesnt let me do that.

Is my only option to replace the RAM?

Thanks!

Hi Fiat124,

I have forwarded this along asking about the RAM frequency. I will reply back when I hear something.

Update: I swapped the 2x A-Data RAM sticks from DIMM0 to DIMM1 and vice versa, reran MemTest86
for ~48 hours and no errors came up. Booted into Windows 7 x64 and within 72 hours had a blue screen.
Reran MemText86 for ~36 hours with no errors. Will see how long until the next blue screen.

I have a Crucial M4 SSD on order. When it arrives, Im going to install it into my AD02 and completely
reload Windows 7 x64 to try and eliminate the OS as a cause of the problem.


supahiro,

I'd love to hear back what Zotac has to say. I REALLY want to keep using this PC, but the blue screens
every 3 days are really annoying.

Thanks!

Update 1: I installed a new Crucial M4 64gb SSD, reinstalled Windows 7 x64 from scratch, installed
SP1, loaded all drivers and applications and went about 3 days and then a BSOD:

0x50 - PAGE_FAULT_IN_NON_PAGED_AREA

I tried to locate the .dmp file so I could check it with WinDBG, DumpCHK or BlueScreenView, but couldnt
find it under C:\Windows\memory.dmp or C:\Windows\MiniDmp, so I'll have to wait for the next BSOD
to try and find out if Windows is crashing due to bad RAM or a bad driver/hardware.

Thanks!
