Added additional 4 Gb (2x2Gb) Corsair TW3X4G1333C9 Ram. Get Stop errors 0x0000001A and 0x000000DE. Tested in both dual slots 1&2 and 3&4 combination with the original ram. PC has original Kingston DDR 1333 (1x2 Gb) modules. The Ram I am adding is the exact specs as the one in the PC. I have updated the Bios to the newest P01-B4 and set to default with optimal settings. I do not see any option to adjust memory settings in the bios to set it to 1066. I have tested the Corsair ram in windows 7 memory diagnostic and also with Memtest overnight and no ram errors.Crash Dump shows Memory Management and Pool Corruption in File Area errors. When used separately without the Kingston Ram in any of the dual slots the PC runs fine. Please help.
Please check the memory timing settings. if your mixing up ram they may not have the same memory timings and require you to go either higher or to the supported settings that either memory can use. for example if corsair runs at 8-8-8-14 and kingston runs at 10-10-10-16 then you will need to bump the settings to 10-10-10-16 since the computer is trying to set the timings for kingston to 8-8-8-14 which it does not support.
Testimonial: "Thanks Tony. Appreciate your help. I will get 2 more sticks of identical ram. This is the downside of purchasing pre-configured retail PC's."
Thank you for the response. The specs are almost identical: Kingston ACR256X64D3U1333C9 (9-9-9-25 @667 MHz) Corsair(Dual channel) XMS3 CM3X2G1333C9 (9-9-9-24 @ 666 MHz), both are 1.5V. Which is probably why the PC boots up fine & reports 8Gb Ram (Win7x64). Only after a few applications are loaded it starts to crash with Stop errors. I will check the memorty timimgs. How do I change memort timings? I do not see any option in the bios to do this. Is there a secret setting in the bios to access advanced options? I have updated to latest bios P01-B4. I have tried Ctrl+F1 and other Ctrl & Alt +F key combinations. Could there be any jumper settings on the board? Ram slots on the board are color coded, 2 black & 2 blue for dual channel. I have flipped Corsair in both. The PC is almost 2 years old and has never had any BSOD with the original Kingston Ram. Right now the Corsair is in the blue slots (#3&4) where the original memory was and it is running fine for 4 days.

Back up system as factory set using recovery console( acer e management) install ram and restore to factory conditions WITH new ram this will auto repair bios to handle ram settings done so on my machine identical to yours my qualifications in computers are adequate enough ( rebuild repair upgrades programming) etc do not try to retime settings allow installation to make changes
Thank you for the response. I created the recovery DVD's when I first got the computer. I then wiped the partiton including the hidden recovery console and re-installed windows 7. So as per your instructions: I will now need to first back up my current partition with Windows 7 somewhere else. Next install the additional ram and then boot into the recovery DVD and re-install the original partitions with all the software that came with the PC. This would enable the Bios to recognize the Ram correctly? I do not need to run any other Acer utility, correct? Simply restore the PC back to the factory default settings (partitions and O/S) and that should auto reset ram settings in the bios. You say you have done this on the same PC as I have? I will try it this weekend and report back. Cheers.
Still unable to add the additional memory. Acer e-revovery management does not start when all 4 slots are used, get error, hardware has changed, and to reinstall windows or contact the manufacturer. Cannot re-install Win7 either, missing boot file error. Once the extra ram is removed able to boot with e-recovery disks or boot into Windows. No Alt+F10 option to start e-recovery after bios post. Can only start it from within Windows and cannot boot into Windows with the extra ram. Reset CMOS, deleted the entire partition, added only 4Gb ( either original or new) & was able to reload O/S from the e-recovery management disks. PC works fine. As soon as I add the additional ram unable to boot into windows or load e-recovery. Cannot even boot with original win7 dvd or Paragon Partition manager. Any other suggestion you can offer? Thanks in advance.

what is the make/model # of your motherboard?
i looked up your computer and unfortunately I am unable to find anything about adjusting the memory timings for this machine. They do have bios updates that you could try and apply and see if it works. Otherwise it is best that you return the ram and purchase an identical ram.
