I have tried everything that i could to see if it was really a MB related problem, it SEEM to be.

My computer freezes, BSOD then restart, w. random error message... It is also double booting.

I made a few test on different operating system to see if it was an issue with my win7 RC. After negative result on Win XP, Debian and Win7 i decided to see if it was related to my memory so i tested it using memtest (full test) and everything was okay. I remove one stick of RAM, changed the 2 ram dimm position, took a look in the BIOS for voltage / timming etc... everything was okay. Upgraded the BIOS to the latest version, changed the video card, took a look at the temperature sensor.

I'm on my second DP45SG and i'm very unsatisfied w. this product. The consumer service is not very helpful, i wouldn't recommend any MB from Intel to anyone. My first spoken language is French, and the north american call center only have English representative, since i don't have a warranty from a computer manufacturer (custom build computer) how i am supposed to get in touch w. someone qualified to heard my request of having a different model as a replacement MB ? (They can't escalate your call from the intel chat, apperently).

As i am aware now, something is clearly wrong w. this motherboard. If anyone is interrested my config is :

-Corsair TX650 PSU

-Corsair XMS3 DHX TW3X4G1333C9DHX

-C2D E8500 @ 3.16GHZ

-ATI 4870 512MB

..

My first DP45SG problem was : http://www.ocforums.com/showthread.php?t=593258

Unable to clear the CMOS ? Yes....

------------------------

I would like to be contacted by a Intel representative, if possible (via email /chat).

Thanks.

Mhmm thanks for your answers.

Unf. i live in Quebec and i don't think i can receive support from a different call center. Well, i will forward my original answer to their customer support email adress...

Hello friends

I have purchased 3 systems with the DP45SG motherboard in the month of march 2009. Still now I can't find a solution for this problem (windows randomly freezes or reboots). I even replaced all the 3 motherboards, but still no use. The problem continues. If someone can figure out the problem, please help me.

My system configuration

Motherboard: Intel DP45SG

Cpu: Core2Quad Q9550

Memory: 4Nos of 2GB Transcend DDR3 1333 MHz

Video: Zotac 9500GT 1GB 128Bit DDR2

Harddrive : 1 TB Seagate HDD

PSU: Zebronics 400Watt

The bios and all the drivers are up to date.

OS : Tried with all latest windows OS (Windows XP 64bit, Vista Ultimate, Business 32 Bit/64 Bit, Windows 7 Ultimate 32/64bit)

It will be helpfull, if someone can give a solution.

thanks,

Senthilkumar

I basically had the same problems. The only solution was to use DDR3-1066 RAM. Remember that the P45 chipset does not officially support DDR3-1333 (see specs on Intel website), only up to DDR3-1066. Especially with more than 2 modules installed, you'll be asking for trouble. Underclocking the 1333 RAM to 1066 didn't work for me, I just got an endless reboot loop. At the price of this MB, I really don't think Intel is hand-picking selected P45 chips that support a 1333 FSB.

Hi,

I would like to just add my two cents.

I have played around with this board for a bit, with various configs and i have had a bit of everyhting in terms of issues and problems with. But did mange to resolve them. I think the main thing with this board is that it is very "delicate" or " moody" i suppose. If you do have 8gbs of RAM i really dont think you are going to get it stable at 1333. I found with2 modules dual channel i could get them stable for 1333, but not for it HAD to be 1066. Althogh ot DOES say on the intel website that 1333 is supported:

Memory

• Four 240-pin  DDR3 SDRAM Dual Inline Memory Module (DIMM) sockets
• Support for DDR3 1333/1066/800 MHz DIMMs
• Support for up to 8 GBΣ of system memory

I think for you guys out tehre still having issues, you need to play around a lot with differents configs and settings in the bios specially the memory!!!

Good luck

I have the DP45SG rev 402 and the DP45SG rev 404. My 402 rev board was rebooting within 4 hours (somtimes 4 minutes) of running everytime. I read someplace about changing the memory voltage so I set mine to 1.75volts and the problem went away immediately. I ran it under load for an entire day without any issue-that was unimaginable before the change. I contacted Intel to make sure that was not a problem and they sent me to this page and said it was fine:

My 404 rev board was losing and gaining time when it would come out of sleep mode, I ran it at 1.75volts but it was running sluggishly, so I dropped it to 1.55volts and it runs great now. If it runs fine all weekend I am closing my open case. If it does not, they said to RMA the 404 board.

So, if you are running the Elpida J1108BABG-DJ-E chips like I am (Mine came from Kingston), then maybe you need to heat them up a little bit also.

Good Luck...
