Anyone here have some hands-on experience with this specific board? Can you clear these up?
GIGABYTE GA-880GMA-UD2H AM3 AMD 880G HDMI SATA 6Gb/s USB 3.0 Micro ATX AMD Motherboard
(this is the Micro ATX version of the GA-880GA-UD2H board)

I need to confirm that this board will in fact let me set the RAM to 1.65 volts and actually run it at 1600.

I'm planning on purchasing this motherboard, but the information I'm seeing in various fora (and even on Gigabyte webpages) is confusing and conflicting. For example, the product page suggests this mobo supports ONLY AthlonII and PhenomII CPUs, but if you look at the CPU compatibility chart, it also includes Sempron 100 series. The Newegg webpage also adds in the Sempron 100 series. (I do NOT care that it supports the Sempron 100 series, what bothers me is the inconsistency in the "specifications")

Plus, the Gigabyte specification page stipulates RAM support = " x 1.5V DDR3" RAM sockets, yet a number of people on various fora say they have SUCCESSFULLY set the voltage to 1.65 volts as required for Corsair DDR3 1600 RAM.

If that's the case, then why the hell does Gigabyte specification for this motherboard stipulate 1.5 volts? That would normally be an upper limit in most specs...not a "typical" or "nominal" value. Ideally, they should provide the range it can be set...but they don't. They know their boards are used by overclockers yet they omit these basic data. Arrgh!

Then there is also the fact that Newegg and Gigabyte specs show the supported RAM speeds are different.
Newegg
DDR3 1800(OC)/1333/1066

Gigabyte
DDR3 2000(OC)/1333/1066

Is there some known reason why they didn't include 1600(OC) in the specs? Is this just an oversight or being incomplete...because other mobo specs include more than 3 timing references so I can't believe it's due to a desire to save space on their webpage. They BOTH skip over 1600 (which seems unusual to me). Again, a number of people on various fora say they have successfully set the RAM to 1600(OC). Unfortunately, I can't verify whether they just ASSUMED that their 1600 setting took place or whether they actually verified it. So again, I'm faced with being unable to confirm this board actually supports 1600 RAM actually running at 1600 (instead of defaulting to some other value like 1333...which some motherboards do).

It also is a nuisance that Gigabyte provides CPU compatibility charts, but does NOT seem to provide RAM compatibility charts for their motherboards. I've heard some great things from overclockers about Gigabyte boards, but not having a RAM compatibility chart (or lookup database)? That's almost criminal.

http://www.newegg.com/Product/Product.aspx?Item=N82E16813128445
DDR3 1800(OC)/1333/1066
(newegg doesn't even mention RAM (or CPU) voltages)

But at Gigabyte's webpage, the specification stipulates RAM voltage (and timing supported):
http://gigabyte.com/products/product-page.aspx?pid=3632#sp
1. 4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory
2. Dual channel memory architecture
3. Support for DDR3 2000(OC)/1333/1066 MHz memory modules


edit:
changed subject to more accurately reflect I'm trying to find out if this motherboard supports changing the RAM voltage to 1.65volts (or even higher?).

I don't, but as a last resort, call and ask? Just a thought as far as the misinformation, perhaps it was added/fixed in a BIOS update and never accounted for in the final documentation.s**tty I know, but a possible explanation.

I've had a support query in for some time now.

But, even if I get a response, I wouldn't trust it very much given the quality of most tech support and the state of their own online documentation.

I'd prefer if possible to get the info from someone here who has actually had the board in hand and seen what the BIOS Settings and OCing can do.

Your Motherboard will support most versions of DDR3 as you indicated. But it's the RAM
that you need to think about and not the Motherboard. The Motherboard will support those
volts (if it supports some kind of config for overclocking) but it's the type and spec of the
RAM that you need to concentrate on to get the supported Voltage you require.

For a new build, I look for the particular RAM I want, then proceed to the manufacture
site. For example, I wanted Corsair DDR3 2000MHz and went to the site.

http://www.corsair.com/

I got this for you (bear in mind, this is an example):


http://www.corsair.com/configurator/product_results.aspx?id=1529925

This is the RAM from Corsair that supports your MotherBoard. The Volts are
typical of 1.5v at under 1600MHz. The Ram will be 1033MHz at stock and probably just
under 1.5v on first boot. The RAM does not run at 1600MHz. You have to OC it to
run at 1600MHz, which'll take you to around or just over the 1.65v.
Note that this RAM in this link I provided is Enthusiast RAM. Try Kingston, OCZ, etc.

Hope this made you understand a bit about your grievance with the MoBo website
info/details on the memory type that suits your board. Just remember that when you
buy ram for OC'ing, even tho (as an example) it will state 1600MHz RAM, it does not
run at that once you build it. This is the Overclocking potential to unlock.

>> Re: RAM Supported by GIGABYTE GA-880GMA-UD2H ?

Thanks, Tam. I'd already done that.

What I have available is a great deal on DDR3 1600 RAM, but it takes 1.65 volts...which as I understood it from various fora GENERALLY isn't a major problem when you start overclocking motherboards. In fact, for these specific RAM several people reported success on other Gigabyte AM3 motherboards, but like I said above, I really would prefer to hear from "our" people if possible...because the mobo spec isn't talking.

So I'm looking for a decent overclocking motherboard that I can confirm supports 1.65 volts while overclocking before I buy it. I know they're out there.

This is my first serious investment into overclocking, and all I'm trying to do is minimize the $$ risk as much as possible.

I know the 1600 RAM has to be "overclocked" on quite a few motherboards, and they usually explicitly say they do support it by using the term "1600(OC)". Some of them also say OC is supported only in 2 specific slots.

But at least some of the mobos I've been looking at don't even mention how adjustable their RAM voltage settings are...which I think is just incredibly incomplete for a specification for a motherboard that supports overclocking.

If they're going to specify the RAM timings they support including overclocking timings, then it should be logical and expected that they also supply the voltage ranges they support for both CPU and RAM, FSB, etc. Maybe not on the retailer's webpage, but it should be in the motherboard specs.

Without those data overclocking is a crapshoot, as far as I'm concerned and it doesn't need to be that way and it shouldn't be that way. The OC timing and voltage data should be readily available, especially when a board is explicitly designed for overclocking.

John, this Motherboard does support this voltage. It has to. It wouldn't be an OverClocking
board if it didn't lol. It supports from 1.30v well past 1.65v and up to 2.1v on the Dram.

Here's a youtube link at a preview of the GA-880MA-UD2H Bios.

http://www.youtube.com/watch?v=GQUPSQ9n07M

and a review of the Motherboard of the BIOS OC functions.

http://www.bit-tech.net/hardware/motherboards/2010/09/24/gigab...h-review/1

The board looks good and has a lot of OC potential and tons of tweaking to do.

From the information you discussed about the RAM at Newegg - this board NOW takes
2000MHz RAM for further OC potential which is excellent.

Don't worry about the rating of the Memory either - what you listed from Newegg,
depends on how serious and how extreme you want to be with your OC'ing.

As for the Risk assessment - overclocking is a lot easier today than it was 3, 4 or more
years ago. MotherBoards designed for Overclocking have thresholds to avoid damage
to hardware (which you can change in BIOS settings) You can't go OTT on OC'ing
and damage components/hardware like you could years ago. You're fortunate enough
to enter into an era of OC'ing that a gran could do! lol I've been overclocking since
2005 and back then it took days, weeks, even months to get an OC stable. Today,
it's so so much easier. So I wouldn't worry too much.

Thanks Tam!

That bit-tech item was great. (although to get the link right you need to take off the "." at the end.

None of the research I've done found either of those links.

The bit-tech item also pointed out lack of heat-sinking on the power regulator circuitry. so that's something to consider too for over-clocking. I've got lots of component heat sinks in my junk box, so I think I've got that covered too.

I'll be using a single graphics card, and the bit-tech review warned me about any card longer than 205mm covering MOST of the 6Gb/s SATA ports where even right-angle plugs won't fit. So that's good to know too!

Oops! Decimal point now removed lol. I don't know how that got there? Maybe I put it there!

Glad to help! I could help you out a lot more, but almost my bedtime over here in Scotland.
