Undervoltable Motherboards: ADD to the list!!
Moderators: NeilBlanchard, Ralf Hutter, sthayashi, Lawrence Lee
Well, I can definetly say that the MSI6308 (KT3) is NOT undervoltable - it's voltage range is from 1.725V to 1.850V - that's enough headroom to O/C, but not undervolt...
The 1.4 GHz XP1600 is designed for 1.75V - I've unlocked mine and overclocked it to an 1.67 GHz (XP2000), and I've been able to undervolt to 1.725V. I'm really tempted to get a new mobo and see just how low I can go with the voltage! BTW, at the 1.67GHz, the CPU's at 46 degrees (volcano 7, panaflo 12V), and stays at 46 degrees when I underclock to 1.05GHz, but drop the panaflo to 5V(for supersilence!). Any problems with these temps?
And any suggestions for a good SocketA mobo with lots of bios features (as well as USB2?) I hate onboard sound and Lan, so I don't care for those...[/i]

Yeah nan0dog, thanks for the advice. I've already bought and installed the Solteknan0dog wrote:Check out the nforce2 boards from Abit and Soltek. They both undervolt to 1.1v. There's a link to the Soltek review around here somewhere, or google it.
Here's MY review of the massively undervoltable SOLTEK FRN7-L:
It's a kickass board! It has nForce2Ultra, which includes niceties like USB2.0, dualDDR, and a lot of user-tweakable features. As for the BIOS, the votlage can be adjusted from 1.1-1.85V, while the FSB can go from 100-230 (this board IS capable of a 200MHz FSB - many reviews are out of date on other websites). I don't know how well the T-bredB's or Barton's are unlocked - I have a Palamino which I've unlocked, and I can raise my 1600XP to a 2100XP! The main con is the lack of HSF mounting holes for sooper-heavy heatsinks. It was also really cheap ($130 Canadian after tax), and has onboard lan and sound (which I don't use for a number of reasons). Oh yeah, and apparently some come with a fan on the northbridge while others don't - just get a zalman NB heatsink if yours has a fan (and hence the smaller HS). Hell - get a zalman anyways - they look threatening
For quietness:
I was able to undervolt my Palamino XP1600 to 1.45V, and with a 5V panaflo on a Volcano 7, I have 57 deg while folding (on-die temperature - not the stupid mobo thermal sensor which says 47deg). It's a perfectly fine temp for the palamino.
Sound interesting.oogabooga wrote:

Does it support SpeedFan?
Bye egghat.
Does it support setting the FanSpeed too? (I had an older Soltek board, which was rather cool, but couldn't set the speed of the fans via software. It took three weeks to confirm this; the Soltek support guy's English was rather bad. But at least they answered; all my questions to Asus are still unanswered ).oogabooga wrote:Yep - that's actually the proggie that I'm currently using to get my temps.

The DFI LANParty KT400A also seem able to undervolt down to 1.1V.
It's in german.

The Gigabyte 7NNXP nforce2 ultra 400 ATX board seems to undervolt to 1.1v. Onboard p-ata and s-ata raid, Intel csa gigabit lan. I just ordered one, so I'll let you know. See review http://www.digital-daily.com/motherboar ... ndex05.htm
Tomshardware is reporting on voltage-range for a handfull of Nfroce2 Ultra 400 Motherboards:
* Abit NF7-S 2.0: 1.1 to 1.85V in 0.05V increments
* Aopen AK79D-400Max: 1.1 to 1.85V in 0.05V increments
* Asus A7N8X Deluxe: 1.65 to 1.85V in 0.025V increments
* DFI LANParty NFII Ultra: 1.1 to 2.00V in 0.025V increments
* Epox EP-8RDA3+: 1.4 to 2.2V in 0.025V increments
* Abit NF7-S 2.0: 1.1 to 1.85V in 0.05V increments
* Aopen AK79D-400Max: 1.1 to 1.85V in 0.05V increments
* Asus A7N8X Deluxe: 1.65 to 1.85V in 0.025V increments
* DFI LANParty NFII Ultra: 1.1 to 2.00V in 0.025V increments
* Epox EP-8RDA3+: 1.4 to 2.2V in 0.025V increments
I'm very glad to contribute to this great website.
I was looking for Albatron motherboards, and while searching I found very good news. According to this and to the original motherboard manual I downloaded from the Albatron site, this is the achievable Vcore range:
Min: 0.8375V
Max: 1.6V
No life for over*! Straightforward P4 undervolting/underclocking!
Albatron PX865PE for candidate.
Bye!

Hi all this is my first post. Since Im a silent-pc fanatic I thought I should add my motherboard to the list. Im using a epox 8k5a2+ which has the following specs.
CPU multiplier can be selected from 6.0X up to 12.0X in 0.5X steps, and from 12X to 15X in 1X steps. VCore can be selected from 1.4V up to 1.85V in 0.025V steps and from 1.85V to 2.20V in 0.05V steps and VMem from 2.50V 3.20V in 0.1V increments.

Beware the AOPEN AK79G and AOPEN MK79G. I very nearly bought one because of the good price and ability to undervolt to 1.1V, but discovered at the last instant that THEY DON'T SUPPORT MULTIPLIER ADJUSTMENT.
I'm looking for an N-forcer which can run a Tbred at 5.5x166 @ 1.1V with 3 DIMMs, MCP-T audio, LAN, onboard VGA w/TV out for a HTPC project.
I'm not too sure about Leadtek motherboards and the layout seems odd, but so far only the Leadtek K7NCR18G pro seems to fit the bill.
UKers can get 'em from www.dabs.com for 95 quid.

Hi!
I've just read the whole thread, and the list of undervoltable motherboards.
I'd like to make some corrections to that list from my personal experience.
All Abit KD7 models -> listed as 1.1-1.85V, but it's also listed in discontinued motherboards as 1.1-2.325, which is the correct answer.
Asus A7V333 (all models) -> One model has not the block of jumpers, the Asus A7V333-X (KT333+VT8235), which is BTW the most easy to find now in shops.
Earlier models of Asus Socket A mobos, also have those blocks of jumpers, meaning that undervolting is also possible with those motherboards...
I'm also looking for Micro-ATX undervoltable motherboards... the first and the only smaller-than-ATX mobo that I've heard of is also the one of Shuttle SN45G...

Re: Abit NF7-S 2.0 undervoltable.
My personal experiences are at least equal to yours, and with some "selected" CPUs better...Vaeltaja wrote:Abit NF7-S v2.0 is CPU undervoltable. In 0.025V increments, if I recall from 1.1V upwards. Currently we have two NF7-S boards running AMD T-BredB 1700+:s at 1.30V (1.6V default) with a slight 5% overclock. Both CPUs are stable through Prime95 and pass memtest86. Note: I do not know whether this degree of undervolting is normal with 1700+ processors though; it is quite possible that we have gotten very lucky.
When Mike has a little spare time to correct and edit my horrible English, he will add an article I sent to him about "Thoroughbred-B Undervolting"

The AOpen MK79G-N is a micro-ATX nForce2 IGP [Crush 18G], nVidia MCP chip board with Integrated GeForce4 MX Graphics, Vcore 1.1-1.85V. As a bonus, it has SilenTek & SilentBIOS. I'd like to get my hands on one!

Another AOpen nForce2 mATX - embedded VGA boards w/ good Vcore control: MK79G-1394
I'm using a Gigabyte GA-8PE800 with a PIV 3.06 processor. The motherboard allows voltage adjustements in 0.0125V steps from 0.8385V to 1.6V. My cpu is currently undervolted to 1.3V. With only 2 fans in the system (PSU and CPU -Zalman 7000alcu at minimum voltage) and an ambient temp of 27C, idle temp is 39C and under full load it is 56C.
With Gigabyte's EasyTune4 you can change the Vcore in windows. EasyTune4 also lets you adjust CPU, GPU, PCI, and memory frequencies in windows. You can monitor CPU temps and the RPM of the fans. This all can also be done in the BIOS.

Have you tested or seen them by yourself? I don't see anywhere that they provide Vcore control...
