It seems like ages ago when Intel released the P45 Express chipset. In fact it was just last June, but that is normally an eternity in the personal computer market. After our first look at the chipset, we were not convinced that it could be successful. The P35 Express chipset was mature, less expensive, and a very popular choice for the first time buyer and enthusiast alike. Anyone needing high-end performance for a CrossFire setup had numerous options to choose from with the X38/X48 based motherboards. What seemed like the final nail in the coffin is that board pricing was closer to X38 territory than the P35 and initial performance numbers just did not wow anyone.

Beyond that, it seemed like the upcoming Nehalem platform was getting more press than the P45. Most of us were wondering out loud why anyone would invest in a brand new chipset based on a previous generation processor when the mother of all platforms was getting ready to launch. Not to mention, except for CrossFire capabilities upgraded from x16/x4 on the P35 to a performance friendly x8/x8 setup, what did the P45 really offer?

As it turns out, this chipset had a lot to offer. Of course, the stars seemed to align perfectly for its march to success. After a few rough patches with early BIOS releases, this chipset became the favorite upgrade choice for the enthusiast due to its incredible front-side bus and memory overclocking capabilities. AMD released two of the best value/performance video cards in recent memory with the HD 4870 / HD 4850 video cards and all of a sudden you could run CrossFire on a mainstream board without spending a fortune. Intel pushed this chipset heavily and the motherboard manufacturers started pumping out various models from the low-end $80 market up to the high-end $250 sector. The P45 was everywhere and available at almost any price point - we last counted about 100 different models available from just about every manufacturer in the business.

It’s hard not to get lost in the sea of available models when searching the web sites at ASUS, MSI, Gigabyte, and others. Thanks to aggressive price cuts on the Core 2 series of processors and with the Core i7 platform regulated to the high-end market until the end of this year, the opportunity for the P45’s star to shine brightly continues for the immediate future. Based on recent information from Intel we can expect to see the P45 around until 2011.

One of the industry's leading supporters of the P45 chipset is Gigabyte. At last count, Gigabyte had fifteen P45 motherboards in their lineup. Gigabyte has already released six new P45 second-generation products based on their Ultra Durable 3 technology. We will be taking an in-depth look at the Ultra Durable 3 technology in separate article shortly. In the meantime, today we are reviewing one of the top models in the Ultra Durable 3 lineup, the GA-EP45-UD3P.

This particular board offers CrossFire support in dual x8 mode, native support for DDR2-1366 memory speeds, a revised cooling system, dual PCI-E Gigabit LAN controllers with teaming, and Dolby Home Theater support via the Realtek ALC889a. Add in an integrated TPM data encryption chip, eight SATA ports, Dynamic Energy Saver power management system, and IEEE 1394a support plus several other features and you just bought the kitchen sink with this board. Speaking of buying, the current retail pricing is around $135 and a $20 rebate is available, meaning there is a lot of value packed into this blue wonder board.

Did the Gigabyte GA-EP45-UD3P impress us? Let’s find out now.

    Hi Gary,

    Excellent review. I'm glad I chose this board when I built my new system a couple of months back.

    However, I have not managed to get eSata fully working on this board. When I plug in an eSata HDD, Vista picks it up but it's listed as an internal disk. Therefore, I cannot remove it from "Safely remove hardware".

    I tried the latest Intel Storage Manager, but that did not help. I have had to resort to using HotSwap.

    Have you come across this during your testing (or has anyone else using this MB experienced and fixed this issue)?

    An 8600 @ 5Ghz+...very nice o/c! I reckon that setup would fetch a pretty penny on Fleabay (unless Gary's using it as his main gaming rig...hehe ;) Reply

    I expected core i7 architecture to use less power than core2 Quad in "idle" mode because it can switch off unused cores. So if I have a computer which is 24/7 in "on" state then the best power efficiency will be to use core 2 Duo. For example if it is used for downloading/uploading from internet.
    It seems I was wrong. Or may be it is a Vista problem failing to switch off unused cores of core i7?

    Have had it since october running my E8400@ 4.2ghz and 525 FSB 24/7

    This board is really a pleasure to work with once you get the hang of the various bios settings. Took awhile back then. Now there is an 1800 post thread at X-treme so info is no longer lacking on any setting.

    This board is a throw back to the good old Abit days of the BH6 and boards like it. Lots of fun.

    LoneWolf15, what 4GB DDR2's are you using? Any problems setting things up? Reply

    "LoneWolf15, what 4GB DDR2's are you using? Any problems setting things up? "

    I apologize here. I used two 2GB modules, not two 4GB ones, and couldn't go back and re-edit.

    I'm using G.Skill Pi DDR2-800 modules which work at 1.8-1.9v with 4-4-4-12 timing. They're available at the `Egg for $45-50 a set with free shipping, and they're hassle free. Almost tempting to get a second set for Windows 7 x64 when it comes out.

    Just wanted to add (even though you didn't ask) I'm using the 2X2gig Reaper ram that has the heatpipe with a huge heatsink on top (making the ram 2-3" taller than it would normally be). There are no clearance issues at all. Reply

    Time to break out the LN2 and see how far it really goes ;) Reply

    I was wondering if you could post a picture of the test setup? Reply

    Let me get one before I tear it down today. Reply
