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

Ah thnx for the tip I gotta rip open an EP35-DS4 tonite 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

Great to hear .

One great thing about the Gigabyte boards is it's ease of use. You can make it as complicated or as easy as you want and it's something I will be emphasising more on in future reviews.Quote

One BIG issue I do have is the lack of fan control via the bios. Dunno if there's something for me to discover, but I like the fact ABit chose for a long time to allow u to vary ALL the fan headers with the temps of 4 different things. Thus far I can only see a cpu one via software, although there is a fixed yes/no option in the bios - not very helpful. I introduced a spare Akasa 3pin pot to stop the rear fans sounding like an aeroplane.Quote

Hey Rastalovich,

Tell me more about this – is this really important?

BTW, others are free to comment.

I would like to know because maybe I can assist with this!

Well, at least I can find out.Quote

Afaic, I consider myself spoilt to have over the years had some great ABit mobos with all the glory that went along with it.

*cough* excuse the sentimentality *cough*

Being serious tho, in conjunction with the uGuru, their mobos, as far back as the amd k6 afaik, have allowed u to manipulate ALL of the 3 pin fan headers on the mobos against either cpu/sys and latterly pwm avg/pwm max also.

Now from an enthusiast pov, in particular - mine, this breaks open so many options in terms of pc cooling, that sure can be covered by purchasing overpriced fan controllers. But put on top of that, the ability to quieten the pc to absolute silence when ur not using it fully.

To give an example of Abit's last carnation, although it's true for the 35/38/48:

Invariably 6x 3 pin headers (1 being 4 on the cpu designated).

Each of them can select a low voltage % or volt, also the high.

Couple with that, the option of the low/high temps to span this over.

Then the option to change each of the 6 to compare the temps of cpu/pwmAV/pwmMax/sys.

(further changes, level wize, can be made by FanEQ in uGuru)

(another +ve is that it doesn't make fan control windows specific, as u dont have to rely on the mobo manufacturers util prog to control it)

This means u can have the fan on ur drives quiet as they only spin faster if,e.g., the SYS temp rises.

The cpu fan, or fans (ofc u can turn the likes of a ninja into a 2 fan-ed device with this mobo) varying with the cpu temp.

Ram cooler, notoriously winey small noises, but not when u vary it's speed with the pc's temp.

Additionally, as on my 38 & 48, u can have a tiny fan on ur pwm/nb/sb that varies similary.

This being said. At the end of the day u can have 6 sets of fans in ur case and not have all of them sounding like tornados. It kinda negates some of the cooling things other case or mobo manufacturers add to their setups in terms of quiet-cooling cos u can stick with the age-old fan system without being noisy.

I don't know that ASUS/MSI/DFI/etc dont do something exactly the same, as tbh I've not been interest whilst ABit were at the fore-front, but looking to the future I will have to make some decisions on who to pip for. To this point the Gigabyte P35-DS4 covers everything I need, except for the fan options above. I believe it does standard cpu control and something else. Outside of that it is a very capable mobo. Overclocking on it was a 3 step process of crazy simplicity.

(Only other issue with the mobo is that it wont boot past the cpu post, kinda hangs displaying the 2nd "M" of "memory", if I have a mouse plugged in the usb port of the Apple aluminum keyboard - not a fault I imagine)Quote
