5 out of 5 eggsIt's a motherboard.

Pros: Plugged it in and it went.

x16 slot is in the third position so larger video cards can clear drive mounting structures in older and smaller cases (but still - measure before you buy - it cut it within millimeters on my old model Antec Sonata.

Cons: Idiotic defaults for some BIOS settings - SATA defaults to legacy IDE emulation mode, which doesn't support NCQ or anything decent and useful about SATA. Remember to flip this setting before installing your OS.

5 out of 5 eggsExcellent entry-level board

Pros: Lots of ports, RAID options, good component layout, passive heatsinks and simple BIOS. Easy to setup and installs W7 RC1 with no driver conflicts right from the DVD.

Cons: It won't bake bread?

5 out of 5 eggsVery sturdy board for a clutz like me.

Pros: I'm not what you call nimble. I have had a few heart stopping slips of a screwdriver on this board and it runs like a champ with an Intel Core 2 Quad Q9400. Excellent.

Cons: Drops some drivers once. No problems after a fresh driver installation.

Other Thoughts: Bios update is a breeze, but not needed to run the newest chips that the board supports.

4 out of 5 eggsFSB oc's to 1950+!!!

Pros: Coming from AMD, I had no idea how to oc an intel cpu with a locked multiplier.

On my e8400 EO stepping (rated 3 GHz), the multi is limited to 9x rated FSB/4, or 9x400 or 3.6 GHz.

The Gigabyte EP45-ud3LR allowed me to hit 4.4 by setting the FSB to 489 (x4=1956), though the Corsair XMS2 DDR2-1066 2x2GB memory had to be lowered to 950 to hit it.

I didn't try to go higher as I was near 68C which is hot for the e8400.

At 4.3 my e8400 ran at 61C prime95 100% after an hour with an OCZ Vendetta cooler, Arctic Silver 5 paste.

I use auto voltage, board sets at 1.376 but it does jump to 1.4 at times (during idle times) which is just above spec.

cpu=9x486=4.37 GHz

ram=2x486=972 MHz

GTX 260 at 754/1258/1577.

Cons: The PCIe 1x seem to run into the heatsink or ram, but I use a USB TV stick anyway.

Gigabyte's service is terrible, they try to find any excuse to deny RMA.

I'm stuck with a dead Gigabyte AMD board that died after I used an aftermarket NB cooler.

It died for a different reason, they didn't care why it died just that I found my own solution for their poor NB design (it idled at 85C, load at 105C. They redesigned the NB in a later edition but denied my RMA based on my solution to that.

I don't know why I bought them again, honestly I'm an idiot. Cost them an egg though.

No Xfire or SLI, but that'll save me money in the long run.

Other Thoughts: Easy to OC once you understand stuff in the BIOS.

Voltage settings allow very precise adjustments.

There's a great deal of voltage settings I don't understand, but with the OC I get on auto who cares, I'll learn them as time goes on.

I wonder if adding 2x2 GB RAM will affect performance, on AMD running 4 sticks of 2 GB 1066 ram would force me to underclock to DDR2 800.

Not bad for the 104 I paid locally for the board before rebate of twentie!

5 out of 5 eggsGreat Cheap P45/ICH10R

Pros: This is a great board from Gigabyte... Very cheap and loaded with all the goodies. Great at overclocking my Q9400, using Xigmatek s1283 was able to hit 3.6GHz with few voltage adjustment. And it runs cool

Cons: Theres only one I could find, they give only 2 SATA cables. Other than that, this board rocks!

Other Thoughts: Intel Q9400 @ 3.0 GHz
GA-EP45-UD3LR
Xigmatek S1283 with retention bracket
4GB Patriot Viper DDR 800 @ 900 MHz (5-6-6-14)
2 X 250GB WD Caviar 7200RPM in raid 0
EVGA 8800GS
Antec Three Hundred & Trio 430W PSU

5 out of 5 eggsExcelent Board!

Pros: Great range of features, Build quality, Had no compatibility issues.

Cons: PATA, and SATA ports are a lil bit of a pita with longer cards in the pci slots. PCIe x1 top 2 slots could interfere with ram if long cards were installed.

Other Thoughts: No issues with the top pcie x1 card with my dlink dwa-556 XP64 driver too boot

Windows XP Pro X64
Q8200 @ 2.8ghz 1600fsb
8Gb Gskil DDR2 800 1.9v 4-4-4-12
2x Hitachi 80Gb 7200rpm SATAII RAID 0
320Gb Segate 7200rpm SATAII
ATI X850xt...for now

5 out of 5 eggsGREAT BOARD!

Pros: There's a reason why Google trusts Gigabyte products. Great quality. I don't know about the "Japanese Capacitors" and "2oz of copper" or anything being really useful/helpful. The price was good at the time and it supports my needs...

Cons: Guess it wasn't free...

Other Thoughts: Purchased the board for EFI-X use. :)
