Gigabyte EP45-UD3P (P45) Motherboard

BIOS Features

The AWARD BIOS of the EP45-UD3P is very similar to most other Gigabyte BIOS, so anyone familiar with Gigabyte motherboards or indeed the AWARD BIOS format will feel right at home here. Skipping the usual sections, we will head right to the business end of the BIOS - the M.I.T (Motherboard Intelligent Tweaker) which is actually the first section in the BIOS.
UD3P Main Screen M.I.T
Again, this BIOS is almost identical to previous Gigabyte P45 motherboards, having the same settings throughout the first page. The majority of settings can be entered either manually or by the use of a sub menu where you scroll through the various settings. This makes for quick and easy application of settings instead of wasting time scrolling through the many settings available.
FSB Clock Drive
The FSB is one of those settings where you really need to input the setting manually, as scrolling through 1100 options could be a little tiresome, not that there any CPU's around capable of such a ludicrous front side bus. CPU and PCIe clock drives can be adjusted in a sub menu, as can the CPU and Northbridge clock skew.
FSB Strap Memory Multi
Automatic FSB strap changes are a thing of the past with the UD3P, as it allows you to set the MCH frequency latch from 200mhz to 400mhz. If you wish to let the board sort the strap out for you then you can choose the strap by the memory divider you settle on.
Subtimings Voltages
The Memory sub timings are basic in comparison to the higher end models, but the 6 main sub timings are there along with the individual channel timing and drive settings. What the UD3P lacks in sub timings it makes up for in voltages. Some very dangerous settings are available here that should satisfy even the most extreme overclocker, hopefully with LN2 to hand. A massive 2.3v on the CPU along with 3v+ for the memory should be enough to eek every last MHz from a CPU, presuming you have the methods with which to cool your silicon at those extreme voltages!
Security chip Health
One oddball setting is the security chip Enabled/Disabled setting. This settings is normally in found bundles along with the settings in the advanced section, allowing a password protected BIOS, so why Gigabyte have chosen to give this somewhat insignificant setting a page by itself is quite beyond me. As with the M.I.T section, the PC health status page has all of the temperature and voltage readouts you could need.
Like the other Gigabyte P45 BIOS before it, the UD3P's BIOS is well laid out, but that irritating jerkiness when scrolling the page is still there, which is a shame.
Let's move on to our test setup and see how  much of an effect these BIOS options have in our overclocking tests...

Nice review Webbo.

It's a tricky judgement to make on this mobo, one of the many they have.

They seem to have done a 'good' job of making a ddr2 mobo, from a ddr3 chipset, and it sorta holds it's own with the competition. Doesn't particularly beat anything out-of-the-water, and neither does it drop way-way back on anything. U see it drop on something and in the next stat it's up again. Average it out and it does 'good'.

I struggle to understand why they bother bolting it down from ddr3, and not just stick with the ddr3 mobos. It could be argued they have both types already, in both 3 and 4 series, so I'm stumped further.

It does a great job in the 3d department, so ur gaming isn't going to suffer in anyway. If ur a Gigabyte fan, it won't exactly let u down and u can drag that ddr2 with u.

Not exactly an eyebrows-raiser, but ok it does 'good'. £115 - yeah ok, it's amongst the competition there too.

Curious about the bios.Quote

Thanks for the feedback as always Rasta. The BIOS is pretty easy to use as with all Gigabyte boards but as with the EXTREME, scrolling through the BIOS is jerky. Not an issue if you only use it once or twice but it can become irratating if your constantly using it.Quote

Not noticed it with the P35's tbh, just the P45's. Like I said it's not a biggie, just something worth mentioning.Quote

Jeez, felt I had to report back. Installed the EP35 DS4 and frankly it's a great mobo. I have no idea of the benchies or anything, but I've installed it in a mATX style case that takes ATX mobos, with a wifi, 3 drives, and hopefully 4 OSes. It's gonna be my util pc, easy to move about.

(had to get this model cos of its SATA port arrangement and the 8 usb ports on the io plate)

Just about got a 8800GT in the case, Q9400, 4 gig, blah blah.

Put an Intel Extreme cooler on the cpu, and simply changed 2 things in the bios. Memory to 2x 333 base (from 2.4 auto), and cranked up the fsb to make the cpu 3g. Piece of cake, idles at under 30 - which I was amazed at.

One special bonus was the ALC889A, dts and the drivers seem to work in Vista 64bit !

With a fsb 1600 also, I will be recommending this mobo for it's ease.Quote
