well the support suck. i battle now for 2 weeks with support to sort out a problem for me. they came back and tell me there is no such problem...

i do have a compatibility broblem with the dp45sg and the q8300 cpu. i test 2 x q8300 cpu's on 3 x dp45sg m/b and it does not post.test m/b with different cpu's and all is working well. test the cpu's on other intel m/b and all it well.

WHAT ANSWER!! THIS IS THERE'S...

"using the system configuration that you provided me with I made a replication with the following system configuration. I came to the conclusion that the Intel Core2 Quad Processor Q8300 is working fine with Intel Desktop Board DP45SG (Bios v 0116) without any problems. There are no incompatible issue as far as we can see. Furthermore we have no specific reports of an incompatiblity between the Intel Desktop Board DP45SG and the Core2 Quad Processor Q8300.

Hope u guys will get a better answer...........that answer is not working for me.

Wel i test it with 400Watt PSU  and 550Watt PSU. If I install my Q9550 onto the m/b it works fine with all the specs, the Q8300 does not post.then i install the Q8300 onto a DG31PR with a 350Watt PSU and it works. They say that is a FSB1333 CPU but But does not work on 1 or the 3 m/b i have, but on an FSB800 m/b it works????????????????????

Hey PC-Tech,

I just installed my video card and i am getting 3 beeps.  Here is my machine set up.  Keep in mind i just purchased all of this equipment before i joined this forum.  Here is the set up:

The DP45SG Intel motherboard

8GB of PC-3-10666 1333MHz Patriot memory

Seagate 1TB SATA drive

550 Watt Power supply

ATI Radeon HD 4670 PCI Express 1GB/GO GDDR3

Intel Core 2 Duo Processor (2.8GHz)

Lite-On Blue Ray DVD palyer

That is my set up but i do have a question reguarding the PCIX video set up.  From what i read and understand, i don't think i need 2 video cards, OR do I?  I am not setting this machine up for gaming but for video editing.  I know i should have done more homework on this seeing i used to be a system builder about 7 years ago but i know alot changes in that period of time so here i am trying to get this to work.  When i built systems in the past using Intel motherboards that was our MB of choice seeing we always seemed to run into problems with the Asus, MSI boards.  Any advice will help!!!  Thanks in advance guys and gals.

The graphics card is a Leadtek 9800GT 512MB..

Hi all,

I have the exact same problem (Hangs/Reboots). This has been going on for the last 2 - 3 months. I have pretty much done everything everyone else has done and the problem remains. I bought 2 of the following and both have the same issue:

Intel DP45SG Board

4 x 2GB Transcend DDR1333

Q9400 CPU

Graphics cards also the same (Gainward Nvidia 8800GTS) but they were bought quite some time back and have been running in other systems until this upgrade. I will be taking in one of the boards in this week to have tested by the supplier and if the resuls are good I'll take the other in as well. Unfortunately the one is a critical business machine that I can't do without for even a day.

I have always only used Intel boards and that is the only brand I sell to clients as well but after this episode I'm seriously rethinking that.

The Intel desktop board support team has been made aware of this whole discussion. They would like you to report (or report again) this case and others like it to Intel Customer Support for further troubleshooting. Once a case or cases have been reported to the ICS contact center, it can be escalated to the board support engineers. It sounds to me like there is some sort of memory compatibility issue with the boards in question.

I've had this board for some time, buying it when it first came out.  It is deffinately not up to the INTEL standard.  I have nothing but INTEL MBs here (four of them) and this was by far the worst.  Here is a list of "issues" I've discovered with this board:

Do not use your case front panel audio connector on the MB AUDIO connector. You'll regret it. The MB connector is not standard to anything I know out there and your sound will constantly break and pop as the MB tries to "sense" the front connector.

Do not use any PROMISE IDE or SATA board in this MB. I have three, the latest being a PROMISE Fastrak TX4310 RAID card.  Causes the computer to constantly reboot as do the all the other PROMISE PCI cards I've installed in this Motherboard. Tried all three PCI slots with the same exact problem for each and every one of them. Two RAID controllers and one IDE. In fact, I'm running zero additional cards on this MB at the present time to insure stability.

The crappy RAID implementation on this board renders it impossible to install VISTA64, so I've reverted to WinXPx86 and installed the VISTA64 on my DX975 which installed without a problem because I used an IDE as the boot drive.  Almost six months and many many tries later, I've had no success with VISTA64 ULTIMATE (brand new copy fresh out of the plastic).  The board is configured in RAID and I've installed 4X1TB drives in RAID5 and one 500GB SATA not included in the ARRAY for the boot drive with a SATA DVD ROM. VISTA64 will report each and every time that the drives are not bootable, or in some wierd configuration not useable by VISTA64.

RANDOM REBOOTING: Yes, I had that problem. Went to two sticks of 1GB fast PATRIOT DDR3 at 1066 (the ram is rated for the next step up but the board won't run it at that speed) and now the problem is gone. I took the 8gig of DDR3 and put it in another computer. I also upgraded to an ATI 4850 and when I did, I had to upgrade from a 550W Antec HE550 and drop in a TAGAN 700W powersupply (weird issues = powersupply and I was having wierd issues which were fixed with the newer powersupply.  The PS was probably marginal anyway for this many drives).

After all that, I can report this board as ROCK STEADY now for quite some time. Not useful for what I wanted, but no problems with the MB now.  It sets in a lowly place to play the random game and be a repository for the house server. It's not capable of performing the rendering and video tasks I had hoped for under 8gig of DDR3 and VISTA64 ULTIMATE. Of course, INTEL won't take it back since it is performing something.......Makes you wonder if it wasn't built for XP, 2gig of RAM and a lowly Q6600 in the first place and never tested above that level.

I hope you find success with your version of the DP45SG. I consider mine an "expensive failure".
