Did some looking. The cuv4x dose support via cpu's. Don't now about the 1.2ghz but it will definitely support the older ones. They were given out by via to reviewers with the c3 cpu.

Well my ASUS CUV4X has jumpers near the Dimm slots marked for VIA CPU, but they have not had the pins soldered in place so are useless. so I guess there are different versions of the motherboard, as I said, mine works OK with a 866MHz C3, but the BIOS reports it as a Pentium II.

Just been doing a little bit of reading and apparently the Nehemiah were supposed to only work with Tualatin-compatible motherboards.

It's a shame one can't select some website that has a database of all CPUs online along with all the motherboards these CPUs are compatible with.

But my guess would be to read the VIA mainboard compatibility list and strike any mobo from that list that's not Tualatin-capable.

Well the only one I have found that is happy with Nehemiah(without really trying) is the ECS P6STP-FN, it's SiS 630 Chipset though and has no AGP port. A chap is selling the board brand new for £2.49 on ebay at the moment. I might try my Celeron Tulatin 1200 in it and see if that works too.

I compiled a real quick 'n dirty list concocted from ingredients from both the vogonswiki Tualatin list, the VIA compatibility list and a few boards I guessed could as well support Tualatin, but will support VIA.

Here it is:

Quick and dirty VIA-list and Tualatin with possibly (and possibly likely) Nehemiah support.
No guarantees here, but I reckon the boards on this list would be a good starting point to see if they support Nehemiah.

Don't forget theres more factors, like BIOS version.

I'll go check out some more.

My abit be62 works with them.

I had to look up the model number and I see you meant "Abit BE6-II", which is a Slot 1 board.
Obviously you must've used a slotket for it to function, but whether the CPU which is mounted on the slotket will work with any one board, really depends also on which slotket you used.

Ok I got just about everything I need for this biuld!
I'm waiting on a motherboard and I'm bidding on a via nic.

It's going to happen!!!

Ok this should be the last post I make here before putting the build together!!!

I have 3 cpu's to pick from. A 700mhz 866mhz and 1.2ghz c3.
I also have a lot of piii CPUs I can use to compare them with!

I'll be using a asus cuv4x mobo.
Via Envy sound card pic
Via nic (not that it would get much use)
S3 (that's owned by via) savage 4 pro video card.
Via pci sata card.

According to both the ASUS website and cpu-upgrade.com the VIAs aren't supported officially, but that doesn't mean your chips won't run in it. You may be pushing the board when making it supply low enough voltages to the CPU.

The CUV4X seems to officially support Mendocino, which I find kinda interesting as not all s370 boards will.

Feel free to keep us informed 😀.

I found a few reviews online were via sent that mobo with c3's.
The manual also states that it supports via c3 cpu's.

Well in that case you're good to go! 😁

I not sure what all it will support. I never seen it used with a Nehemiah and I'm not sure if it would work with one, but I seen it used with older C3 and the manual says it supports via Cyrix III to be exact. I can't see it not working with Samuel 2 or Ezra cpu. But Nehemiah might be pushing it. I wonder if that pin mod used for Tualatin cpu's would work? or maybe some other pin mod?

I don't think Nehemiah even needs to be pin-modded to be able to run in pre-Tualatin boards?
The one time I tried it in a Coppermine board (ASUS s370 board but can't remember the exact model anymore) it would post at the correct speed and CPU voltage, while a Tualatin should in theory not work because Intel basically switched a couple pins around.

Ok I see. I thought they did the same thing seeing the 1.45v and reading that they don't work in pre-Tualatin boards.
I'll find out.

Frankly, I don't really know why certain boards (supposedly) work with C3 and why some don't, it may be minimum voltage to the CPU or BIOS support or some other variable?

Minimum voltage would not be a problem. But my be6-ii runs c3 cpu's at 3.5v stock. I have to go in and adjust it.
Anyway I'll test all the c3's I have in every slot1 and sk370 bord I can get my hands on and report back.

Been doing some more reading. Looks like most my motherboards with a i815 or VIA 693A/694X/694T chip set will work with Nehemiah. But some will need a bios update according to toms hardware.

This review http://ixbtlabs.com/articles2/roundupmobo/via … 3-nehemiah.html
Say that Nehemiah will on work on a Tualatin board and even talks of the pin mod.

The review mentions it will work on Tualatin boards (which is kinda a given) and I read about a pencil trick (which is kinda redundant since the multi can also be set through software. Didn't read anything about a pin mod though.

What I find a little bit odd though, is that in this article there is mention about 1GHz, 1.06GHz, 1.13GHz and the 1.2GHz, but I don't remember hearing an actual user talk about a Nehemiah that's not 1GHz or 1.2GHz.

I did some browsing myself and found this page which describes that 3 pins must be prevented from being connected with the motherboard, or it will simply not run.

It also describes some additional modding by connecting certain pins in case the voltage isn't set correctly by the motherboard, I should go find my silverpaint 🤣.

Of course there are adapters and other options, but breaking a few pins would be easy and I got some spare chips anyway.

But I don't think Nehemiah needs a pin mod in order to run in a Coppermine board (Tualatin should officially never even POST without a pin mod in a Coppermine board, this is why Intel changed these pins in the first place), unless theres some other problem.

Interesting read and beginner-friendly. Only thing to watch out for is to not break the wrong pins because you accidentally mirror the pics 🤣

Based on data from the Ultimate 686 Benchmark Comparison, a Via C3 Nehemiah running at 1200 MHz would perform similarly to a PIII-700 in Quake II. A Nehemiah running at 1400 MHz performs like a PIII-800. That is with the PIII's using a 100 MHz FSB and the Nehemiah using a 133 MHz FSB. I run my Nehemiah at 1400 MHz and stock rated voltage. It does feel faster in Windows compared to my PIII-850 build.

That sounds cool! Looks like it will have all the power I need if what you say it true. I need about a 700-750mhz piii to do what all I need.
But looking at benchmark subs on HWbot I'd put is more around a k6-2/3 or Pii, only time will tell if it has the power I need.
If I can play MW4 I'd be more then happy and I played that game on a 550mhz Katmai Piii @600mhz back in the day if memory serves me correct.

But for the most part no game I'll play on the system will need even a Piii let alone a pii. Most of the games will do grate with a 120mhz p5.

EDIT:
I'll be sure to do a lot of bench marking on the system once it's all said and done!
