Just wanted to report my experience. After I ordered the DP45SG I had
some misgivings about that particular board. My experience wasn't as
bad as some people's, but I found this to be a bit quirky and thought
I'd pass that on.
What I built: DP45SG Motherboard + Q9550 Core2 Quad + 4 GB of DDR3
The Good: Well equipped, very stable -- once you sort out the quirks.
The Bad: Well...
1. Picky about RAM. The first 2 sticks (of PNY DDR3 1333) would work
for about 2 hours if you started with the machine stone cold, and then
start f*cking up -- spontaneous resets, application errors.
2. Not knowing whether the board itself was bad, I got another
motherboard and tried the CPU and RAM in it -- same result. So I got a
couple of sticks of no-name 1GB DDR3 local to try.
3. I replaced the PNY with some Crucial Ballistix DDR3 -- these are
rated 6-6-6-20, but this motherboard 'detects' them as 9-9-9-24, and
if I tried setting them to their rated speed in the BIOS, the system
4. If you monkey around with BIOS settings, occasionally the board
gets in a state where the network doesn't initialize properly. This is
fixed by a total powerdown for a few minutes -- i.e. turn off the
power supply switch or unplug it from the wall.
5. The Crucial Ballistix sticks are rated for 1.8 volts. According to
what I've read on various boards, the RAM may not be recognized at all
because the board defaults to 1.5volts. I think the latest BIOS is
probably fixed with respect to that issue, but you can't flash the
BIOS without memory. The only solution is to put a stick of 1.5v RAM
in, use the BIOS to jack up the voltage to 1.8 volts, and then stick
your 1.8V sticks in.
Or, of course, you can make sure that the sticks you buy are 1.5v nominal.
6. The board is less forgiving when you use 2GB sticks. With 2 1GB RAM
sticks I could clock the CPU up beyond 3 GHZ with no tweaks besides
the bus speed. With 2x2GB it's only stable at the stock speed. At
this point I'd be scared to even try 4 2GB sticks.
So .. would I recommend this board? Well if I had to do it all over
again I would have gotten one of the Gigabyte boards based on this
chipset. About 20% less in price, and I haven't seen as many
complaints about it on the message boards. On the other hand, like I
said, once I sorted out the RAM issues it has been extremely stable,
and I have faith in the Intel build quality.
