MSI P55-GD65 - Mid-Range P55 for the Masses

Our board of interest today is the MSI P55-GD65. You can purchase this board for around $160 at various e-tailors.
MSI P55-GD65 Feature Set
MSI includes a full featured set of components like the Realtek ALC 889 HD audio codec, dual Realtek RTL8111D Gigabit LAN controllers, Via VT6315N 1394a chipset, powered JMB363 eSATA/USB port on the I/O panel, and full support for the Core i7/i5 S1156 processor series.
MSI includes an extensive accessories bundle. You get the standard rear I/O panel cover along with 1 x IDE cable, 1 x Floppy cable, 4 x SATA cables, 1 x SATA power cables, SLI and CF bridges, a USB bracket, an informative manual, quick installation guide,OC Genie guide, Winki Guide, and two software CDs.
Of note in the software package is Winki. This is a Linux-based operating system similar to ASUS’ ExpressGate. Unlike ExpressGate, you boot Winki off the DVD or off a USB thumb drive once it is setup. Winki includes Open Office, Photo Viewer, Instant Messaging, Web and Skype functionality without booting into your primary OS .
BIOS
The BIOS layout is very good and offers a significant amount of settings for overclocking. MSI’s Cell Menu is where all the action takes place with a wide variety of adjustments including the CPU Core, PLL, VTT, PCH, VDimm and VRef voltages. Each of the settings is very granular and offers just about any range that a user could want or need. Clock and PCIe skews are not available but generally are not needed in this range.
One extremely nice function that MSI includes is that frequency and timing changes are directly visible in the BIOS when values are being changed. Overclocking profiles can be saved, loaded and individually named in one of the available eight slots. MSI's M-Flash (in-BIOS updating) worked very well with our board not having a problem with the BIOS being flashed 30 times in our testing. One item missing from the board is some type of BIOS backup or redundancy system that we find on the ASUS and Gigabyte boards in this price range.
MSI's BIOS-level fan speed control options are an improvement over other P55 boards, but not perfect. Users can select a target CPU fan speed between 40 and 70°C while setting a minimum fan speed between zero and 87.5% in 12.5% increments. The two system fan headers are only capable of speed changes with settings at 50, 75, or 100%. Unfortunately, they cannot be controlled by system temperature changes.

The lack of information regarding PCIe slot assignment when different slots are populated has been SORELY missing from all P55 mobo reviews. It's either laziness or an attempt to cover up shortcomings but it seems pretty important to me - people actually expect to use slots that are present on the board, ya know?I STILL haven't seen an answer to how many lanes the primary graphics slot keeps when the secondary graphics slot is populated with a 1x or 4x card! This affects anyone who has a graphics card and sound card, or TV tuner, or disk controller and given the layout of many boards you're likely going to have to use the secondary graphics slot for those devices.
I am also bothered by the lack of C2Q benchmarks. Loads of people have them and asking whether i5 in particular is a worthwhile upgrade is being ignored.

There are two kinds of P55 mbs:1. Non SLI: The PCI Express 2.0 x16 link does not split.
2. SLI x8: The PCI Express 2.0 link splits into two x8 links, usually SLI-certified by NVIDIA
3. SLI x16: The nForce 200 chip is equipped for 2-way SLI: x16, x16 and 3-way SLI: x16, x8, x8.
Most mb of the first type also have a second PCI Express x16 slot which is connected to P55 and works at x4 (1.x in bandwidth).
MSI P55-GD65 is of the second type. If you insert a PCI Express device (of whatever lanes) in the second PCI Express x16 2.0 slot (electrically x8), the first PCI Express x16 2.0 slot also works only at x8.
A problem of P55-GD65 is that the severe (?) limitation of the PCI Express x4 slot is not mentioned in its product page or the manual at all. For example, suppose that a user is using a PCIe x1 sound card in the first PCIe x1 slot and a 2-slot graphics card. If he wants to use a PCIe x1 TV tuner card and insert it in the PCIe x4 slot, then he will suddenly find that his sound card stops working! So he has to use the second PCI Express 2.0 x16 for the TV tuner. Then this decreases the speed of the graphic card to x8!! Although practically this is not a big issue, this limitation still should be mentioned somewhere in the product page or the manual.
"the layout of this board is just fantastic, especially the PCIe/PCI layout." ?? It looks like Gary Key is simply ignorant of this. ASUS and ASRock mbs have much better board layouts in this respect: all expansion slots actually work!

Exactly the type of scenario that no mobo reviews have mentioned and which I was thinking of. Thank you for spelling it out.crab nebula - Tuesday, October 13, 2009 - link
Correction: "There are two kinds of P55 mbs" has to be "There are three kinds of P55 mbs". (The fourth type would be those that use Lucid Hydra 200.)lopri - Sunday, October 11, 2009 - link
I don't know how you don't see PCI Express slot information from the reviews so far? They have been clearly explained or are in the board specification page. There was even a special article regarding P55 chipset PCI Express.MadMan007 - Monday, October 12, 2009 - link
You need to reread and comprehend my post. I'm not asking for specs, obviously those are easy to find, but how lanes get assigned when slots are occupied especially with something other than a graphics card. I guess all reviewers are too lazy to put anything but one or two graphics cards in their test mobos.lopri - Monday, October 12, 2009 - link
I didn't go back and re-read the reviews, but at the time when I read them I was able to tell how the lanes are assigned on a given board. It's not like there are multitude of choices available.. All P55 boards so far (maybe except the one w/ NF200) support either a x16 lane or two x8 lanes from the CPU. Everything else belongs to the PCH and if I remember correctly all reviews made it clear when a physical x16 slot (x4 electrically) belongs to the south bridge.MadMan007 - Monday, October 12, 2009 - link
You still fail to comprehend and say it like I'm a moron who can't read a chipset diagram but your other link at least answered the question about the CPU-based lanes.lopri - Monday, October 12, 2009 - link

That is a video card review so no it's not been spelled out in mobo reviews. It's what I figured but hoped the lane splitter chips might be smarter. Thanks for the link though.
