Intel DP45SG and 2 pairs of TWIN3X2048-1333C9DHX = only 3GB

After install everything (processor , memory , hard drive, etc etc) I was able to browse MoBo Bios which correctly reports 4GB at 1333Mhz .

 

Here start the nightmare. When i try to install Vista 64 or XP64 both fail after load all drivers(I wasnt able to see the second part of setup(with interface) , computer reset exactly after loading all drivers with BSoD 0000x8E or 0000x7E. Checking Microsoft´s support i discover that 000x8E or 7E is related with SATA so i (replace HD , add Intel´s Sata Drivers , read all intel/samsung foruns about it) nothing same problem again and again.

 

Completely clueless i´ve decide to remove memory leaving just 1GB of memory and.... It works! Vista 64 and XP 64 install without any problem. Cursing microsoft BSoD stupid messages i decide to shutdown computer and add all memory and see if it works.

 

It didnt ! and now i cant even acess my bios!. So i remove memory leaving now just 2GB and it works! I can acess BIOS and Vista Boots correctly and report 2GB... The "you know what lets try 3GB" spirit came up and i did it again. Shutdown/Poweroff add memory 1 more Gb and it works again... (Completely Clueless) :-S

 

So to end this wonderful story my system work with 3GB but not 4GB. All memories are fine , i am saying that because i replace memories between banks to see if it report a bad memory but it works without any problem if i stack only 3GB but not 4GB. Does anyone ever face a problem like that ?

 

Thanks in Advance

Fixed.

 

For MoBo DP45SG you must install windows Vista or XP with 1-3 GB of Ram.

My memory is 1333Mhz but i suppose its valid for other speeds.

 

Are you up and running at 1333MHz with all 4 modules? Did the updates and service pack resolve the issue?
