Hi, Scorpiono. I had the same problem.
To fix it you must change BIOS settings: change memory configuration status from "AUTO" to "MANUAL" and set 1333 MHz.
If it doesn't help (I'm testing this now and will test 10-12 days and wait for result, so I am not sure 100% how it works), then you must set memory speed to 1066 MHz - it works 100%. But I think that problem is the wrong automatic setup in BIOS at memory configuration section.
I hope the next BIOS update will fix the problem.
P. S. If you change RAM settings from "AUTO" to "MANUAL" the computer will start, then shutdown and than start again (it needed to read manual RAM settings, cause at startup default RAM settings loading) - that's normal.
I hope it helps you
Thanks for the information - I have tried that via trial-error 2 months ago and it's exactly the fix I needed.
It shuts down and then reboots on startup but other than that everything is normal, no more BSODs and stuff.
The fix was: setting manual ram from 1333 to 1066. I have tried 1333 at 1.65V, it worked too but still gave BSOD every 2-3 days. The 1066 is very stable and the difference in speed is not seen by my eye.
My question would be: why does it work in 1066 and not in 1333?
Cheers and thanks again,
I hope that's the BIOS bug. But anyway I will send an email to the Intel tech support. And if this is not BIOS problem (technical, hardware problem for example), then I'll replace the board.
There is the same problem:
I would like to try help. Because I have this same board running a q9550 and 8gigs DDR3-1333 and dual HD4770 cards . My Question is What are you using for a power supplie. The min. spec. for a barebones unit is 460 watts , I am using a 650 watt No problems . Have you checked your line volts all 4 types 3.5 V all the to 12 V. To see if you are in range .??
What I have done was to switch from my 500W power supply to an amazing 1000W, still the same problem.
Turning it to 1066 from 1333 (which it's ment to work at) did the trick, stable now!
Intel DP45SG, Core 2 Quad Q9650 3.0 GHz, 2 x Kingston DDR3 2048MB PC10666 1333MHz (KVR1333D3N9/2G), nVidia GTX285 1 Gb DDR3, Hiper HPU-5K770 770W, SATA-II 1Tb Seagate Barracuda 7200.12 (32 Mb cache) + 320 Gb Seagate Barracuda 7200.12 (16 Mb cache).
And changing RAM parameters is helpful at any rate.
I found out the Hard way that 10666, would not work right, But ( 10600 ) Would work, I not realy sure about except the 10666 was designed for a triple , Where the 10600 was designed for dual channel . If you have any DDR3-1333 Mhz 10600 try one stick and see what happens . The Other problem this board has they are notoris for having a bad connection in channel Dimm 0 , I had to put one ram stick in channel B Dimm 0 , to find this ( first board ) had to RMA. Second board worked fine But only on 10600.
Unless you are tring to OC the DDR3-1333-10600, should Be at 1.5 volts , ( unless you want a overheating problem??
BIOS Udate 0125 released today. Hope, this will resolve the problem. Trying....
Sounds Good , But Please don't try running at 1.65 volts you will get a overheating problem Unless you are going to buy a RAM cooler.Another Question is your RAM ( 10600 ) or ( 10666 ). It makes a difference??
My RAM is 10666.... I don't change any voltage settings, they stay at default range. And BIOS was at optimal settings, I've just changed the RAM configuration setting type from "AUTO" to "MANUAL". When it was "AUTO" the computer was not stable. Changing to "MANUAL" and 1066 MHz was the way to fix this problem.
And now, when new BIOS released, I've set RAM configuration to "AUTO" and I'm waiting for result.
I had problems with the 10666 and sent it back and got 10600, then it would clock at 1333Mhz in auto or manuel and is stable either way , There's something about the 10666 that this board don't like , When I went to DDR3-1333-10600 it solved all my RAM problems.
A Q9650 is 1333 FSB and you should be able to macth that .
Let me know if this fixed the problem at 1333mhz, right now it's perfectly stable but at 1066.
