World-renown mainboard and graphics card manufacturer, MSI, has attracted the attention of major worldwide media and power users since the launch of its Xtreme Speed P55 mainboard series. Not only does this series boast a total feature set and specs, but the Xtreme Speed P55 features many MSI-exclusive performance enhancing designs. The series has received wide media acclaim for its outstanding overclocking capabilities, especially the P55 series’ flagship product, the P55-GD55.

Featuring DrMOS and OC Genie, this mainboard's overclocking capabilities are truly amazing. The Taiwan overclocker, Coolaler, was able to overclock the Intel Core i7 860 CPU (2.8GHz)to 5.39 GHz with MSI’s P55-GD80 mainboard, breaking the world record and pushing the processor 92% past its set frequency. This performance surpasses the competition, and beautifully demonstrates MSI's P55 series overclocking prowess.

The MSI P55-GD55 owes much of its outstanding overclocking ability to its equipped MSI-exclusive technologies, such as the one second auto-overclocking feature OC Genie and 1>4 phase total DrMOS power supply design. Other features include the real-time overclocking function Direct OC, Live update and backup feature M-Flash, Power eSATA that acts as both a power source and two eSATA ports, etc. These features coupled with the mainboard's spec set and performance make the MSI P55-GD55 the hottest P55 product around.

3 out of 5 eggs

Pros: I purchased this motherboard strictly on price and my positive experience with a socket 478 MSI motherboard many years ago. I have a Xeon X3440 Processor with an EVGA GeForce 9800 GT Video Card installed in this one, and upon turning it on, I was thrilled to see it boot and appear to run perfectly with excellent benchmark results.

Cons: My problem started when I attempted to install any PCI device (i.e. TV card, modem, etc.), as it would not recognize it. Seeing that my BIOS version 1.3 was old, I flashed it to the latest 1.9 with no success. A quick call to tech support suggested my PCI controller was defective and they would be happy to RMA it. After considering that since I really only wanted to to add a TV card, I'll go with a PCI-E one and spend the extra $20 rather than disassemble and go through the hassle of sending, waiting for a replacement and then rebuilding. Of course now with the extra cost, I should have gone with a better motherboard such as an Asus or Chaintech in the first place. The only other thoughts I have vis-a-vis this motherboard is that the IDE connector is too far from my DVD-writer and CDR-writer even after moving them to the lower external bays, and since my video card is so wide, I esentially have only one usable PCI-E x1 slot. One is covered entirely and the other is too close to the vid

2 out of 5 eggsIt works, but...

Pros: -Affordable
-eSATA
-Convenient power button on motherboard

Cons: -BIOS wake from USB doesn't respond to a Logitech G15 keyboard (rev 2) or mouse that's connected through it.

When the system goes to sleep, the BIOS kills power to the USB controller unless there is a plain keyboard or mouse connected to it. Seriously, MSI? Your BIOS still can't tell when USB composite device or logical hub represents input devices?

-Crashes when resuming from hibernation.

I've reinstalled Windows twice and made sure to get the latest chipset drivers direct from Intel. For the extra SATA controller, I got the latest drivers and system BIOS from MSI.

-MSI's ticketing system is a joke and doesn't work.

As a result, I haven't been able to get these issues resolved.

-MSI software is a mess. Sometimes the web site has more up-to-date software than the "Live Update" app. Sometimes it downloads software and never installs it. Sometimes it misidentifies your system and downloads the wrong software.

Other Thoughts: I'd still recommend MSI if you're looking for something cheap. It was definitely the cheapest P55 board with these features at the time I got it. Be prepared to return the product if you can't get any help from MSI.

2 out of 5 eggsBoard failed after a few months

Pros: Worked well at first.

Cons: started waking up to find system was powered off. Eventually I could not start the system. Turns out the board failed after about 4-5 months.

Other Thoughts: I wish I had spent more money and bought a better board. I had posted a positive review earlier, before I started having trouble.

4 out of 5 eggsnot bad.

Pros: does the job needed.

Cons: I do not like the placements on the mobo. I have a bottom psu mount and the wire barely, and I mean barely reach the processor pins on the top left.

the ribbon cable is all the way on the bottom to the far left. Couldn't they put it on the right or on the side or something?

I left like some things are really placed far from one another.

also if you get a large heatsink usually meant for overclocking becareful because some might block your ram slots.

Other Thoughts: I'm actually interested in crossfire this thing.

this is my video card:
XFX HD-585X-ZNFC Radeon HD 5850 1GB 256-bit DDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card w/ Eyefinity

in a year i hope to crossfire with a second. Any info on your views of crossfireing on this mobo let me know. Eugenemak@live.com

4 out of 5 eggs

Pros: Great board for the price. Has no problems to speak of and the automatic overclocking system in it make it easy if you chose to overclock with almost no tinkering needed.

Cons: As someone else said, the location of the IDE and floppy port (I use one IDE from an old hard drive I have) is in a less than desirable location. Lost a star for that.

Other Thoughts: I'm starting to regret going with the 1156 board instead of the 1366, but price-wise it was a jump, and if you're trying to squeeze the best price out of your case, for the most current functionality, this is the way to go.

4 out of 5 eggsGreat - Don't Xfire/SLI

Pros: This has easily been summed up by the tons of other comments available. I would happen to agree with all of them.

Cons: The one reason I wrote this is to attempt to warn others against trying to run Xfire/SLI on this board.

The board has two PCI-E slots. One is PCI-E 2.0 running at x16 while the second is PCI-E running at x4. Due to how xfire/SLI work, both cards run at the slowest cards speed (which will be x4).

What I'm getting at here is, you will see a SIGNIFICANT loss in performance running an Xfire/SLI setup on this board.

4 out of 5 eggsexcellent board, but one small problem

Pros: Great board, runs every game I tried great. Easiest overclock ever- one button press, powered up and my core i7 860 was running at 3.61 ghz. Stable board.

Cons: I have 8 gigs of DDR3. and for some reason in windows 7 64 bit it says I have 8 gigs, but only 3.99 usable). I noticed this after using the auto overclock feature, because I can't remember if all 8 gigs were usable before the auto oc I am not sure if the 2 things are related.

Other Thoughts: I'm so glad I upgraded. I deducted 1 egg for only allowing 4 of the 8 gigs in win 7.

1 out of 5 eggs

Pros: None.

Cons: I purchased (2) MSI P55-GD55 mother boards to build (2) seperate machines. Neither would post with the following items installed:

Intel i5-750 CPU
Patriot PSD32G13332 DDR3 1333 RAM (included in compatible memory list for P55-GD55 motherboard)
Antec BP550 550W Power supply
ATI Radeon 5770 PCI 2.0 graphics card

I attempted to post both motherboards with all these components in every possible combination but the neither would post. All componenets above were listed as compatible with this MSI board!

I returned both MSI boards to Newegg and purchased (2) Asus P7P55 LX motherboards instead. Both Asus motherboards worked perfectly with the componenets listed above. Both PC's are completely finsished running Windows 64 bit perfectly.

MSI obviously has some work to do with compatibilty. I will not be buying MSI motherboards again. I reccomend everyone do the same.

5 out of 5 eggsawesome

Pros: -the color looks sweet
-oc genie is cool
-plenty of bios options(see below for related con)
-my system stays cool(i think its idle is in the low 20s)
-plenty of USB ports on the back, one of the main reasons i bought this board.
-the on board audio is more than enough for the average user.

Cons: -although there are plenty of options in the bios, i had a friend whos very knowledgable in the IT field OC my i7-860 for me since ive never OC'd before, and he didnt understand why the BIOS would make some features unaccessible one minute and accessible the next.
-control center OC'ing software is junk.
-the front panel audio connectors are on the far side of the board...but why?

Other Thoughts: build:

5 out of 5 eggs

Pros: Excellent motherboard! I had this thing running perfectly on the first boot and it has been running ever since. I have had it running for 1 month and it is has been very stable. I do not overclock anything, so I cannot comment on that aspect. However, overclocking should not be used to evaluate a motherboard unless the board claims to be built for that anyway.

Cons: None that I can find.

Other Thoughts: I am running...
i5-750
Corsair 4GB DDR3 - 1333
Sapphire Radeon 5770 (VaporX)
