Gigabyte GA-EP45-UD3P - P45 at its Finest

Power Consumption
We measured "system" power consumption at the wall outlet using a Watts Up Pro power meter. We do not include the power numbers for a monitor or external speakers; however, we do install a set of headphones to the audio out jack. We also turn on all peripherals in the BIOS along with enabling all power saving features in the BIOS. Power consumption was measured at idle after 15 minutes of inactivity and under load while measuring the average power consumption of the Ranch benchmark in Far Cry 2. Vista's power management option is set to balanced performance mode and the prefetch folder is cleared for each test. Our two tests consist of the standard BIOS power savings mode and a second test using the energy saving applications provided by each supplier.
At idle with the BIOS only setup, the ASUS and MSI boards have the lowest power usage and are followed by the GIGABYTE board. Our idle numbers with the power saving numbers have MSI in the lead, something we have noticed across their DRMOS product lines. Implementing DES on the GIGABYTE board saves about 4W at idle. Our first test with the DES application on the included driver CD did not generate any power savings. We downloaded the latest version off the website and were rewarded with measurable power savings.
The load numbers favor the MSI board again with the ASUS and GIGABYTE close behind. Once we implement the power saving applications, the MSI P45 Platinum has a reduction of 6W and takes the lead again. The GIGABYTE board with DES turned actually matches the 6W reduction. The ASUS board only drops 2W with EPU6 implemented.

I'm guessing the 1250 kit you guys managed to clock at 1300 was Corsair's TWIN2X2048-10000C5DF. I have a set of those, but haven't tested with my UD3P yet; however I got my Geil DDR2-1160 C4 kit up to DDR2-1333 C5 on this board with only 2.48V using the 1333 OC profile: http://i4memory.com/f90/gigabyte-ep45-ud3p-memory-...">http://i4memory.com/f90/gigabyte-ep45-ud3p-memory-...This board is too much fun!

Yes, it is the Corsair kit and it was an early review sample to boot. Corsair sent us a new SPD and I managed to hit 1333 this morning at 2.50V on it, so I can report that 1333 is stable on this board now after a few runs of Crysis and PCMark Vantage. :)GhettoFly - Wednesday, February 11, 2009 - link
It just seems a bit odd advertising DDR2-1366+ OC capabilities when the ICs needed for such clocks (D9GMH/GKX) are EOL :px86 64 - Sunday, February 15, 2009 - link
I'm still seeing some around and very cheap compared to what they used to be. You can pick up two 2x1GB (4GB) kits of PC2-10400 or PC2-9600 for under $275-$300 US.I think there are third party manufacturers who are still making the D9GMH\GKX, etc, because companies like Cellshock (now recently defunct) and Team Group (active) are still selling both of the most popular flavors of D9. Team is very big in Asia so it's not like they are some small niche company like Cellshock moving a small quantity of old stock. All of Team Group's Xtreem memory (not the "Dark" branding) is either GMH or GKX. How else to explain the constant flow of Micron D9 IC's to certain companies? Could there be that much stock still left over in Asia where they are selling them this long after they were discontinued?? I would be surprised.

It has to be old stock of the ICs at least; when you look at the codes on the ICs themselves (not the D9Gxx code, but like 7KD22) I'm pretty sure the first number indicates the year of manufacture, 7 being 2007, 6 being 2006, etc. I haven't see any Micron RevD chips that have those codes staring with 8 even on sticks with a 2008 production date, for example my Geil 1160 C4 and Team Xtreem 9600 kits, the ICs on both have that code starting with a 7.Mr Roboto - Wednesday, February 18, 2009 - link
I don't know what the number is on the IC's themselves but you can check the manufacture date of your memory using a monitoring program like Everest.I have a set of Team's and using Everest they say the 14th week of 2008 as the date or manufacture.
Whether or not the IC's were made then or the modules themselves is debatable.

I think you might be right. I just pulled the spreaders off my Team 1200Mhz and sure enough it starts with a 7. I hope they don't run out anytime soon because it's so much fun to push this stuff :)It's weird, this has to be the first time in a long time that I'm happy with "last generation" hardware. I just don't see the benefit of i7 and DDR3 right now. I'm enjoying the rock solid P45, excellent inexpensive dual and quad Penryn's and dirt cheap high performance memory. I'd rather buy double the current hardware then spend the same amount for an entry level i7 system and get a 20% increase in performance. I'm sure the i7 will make a great server or HPC but I'm not impressed to much with the desktop parts. We need some multithreaded applications first. Software is seriously lagging.
I'll wait for the die shrink and in the mean time stick with my DDR2 and D9GKX\GMH :)

Also here's a picture of a TG kit from a review at XBit Labs from the summer of 2007 and it's marked with a 6 which would be in line with the markings on the recent chips, just one year back.http://www.xbitlabs.com/images/memory/team-xtreem/...">http://www.xbitlabs.com/images/memory/team-xtreem/...

Looks like I have to eat my words about no D9 being manufactured in 2008, these are powering the G.Skill 2GBHK sticks I got in today.http://www.xtremesystems.org/forums/showpost.php?p...">http://www.xtremesystems.org/forums/showpost.php?p...

Great article Gary! I have built approximately 10 systems so far with this board or it's single PCIe X16 twin UD3R, and the "C" version with the DDR3/DDR2 slots. My experiences with each are just as pleasing as you have reported. My own system is the C version with a Q9550 slightly overclocked to 3.4GHz. I am excited to see the followup on the Ultra Durable 3 technology.I am equally or even more excited that you are testing the support of Gigabyte and other manufacturers. I have built over 100 systems using gigabyte P35/G35 and now P45/G45 boards in the past year and a half and I honestly nearly quit using them over some issues with the G45 board when it was first released. It wasn't even close to stable but subsequent bios'es corrected all my complaints. I could get no response from Gigabyte during that time and was pretty pist off! Interestingly enough, I just about switched all my builds to Asus, but I was reminded of past problems with them on my first P45Q build when I went to download the newest drivers! Why does a multibillion dollar company like Asus insist on having a dog-assed slow website that is so painful to negotiate? At times during the day, one can't even get a page to open without timing out! And it's been that way for years! Gigabyte! You owe Asus a "save" on that one! Kudos to Anands crew for taking up these frustrations with the mfgs! Great article!
