Coming in here with a question. If anybody recalls, NT4 had a version with support for 8 processing cores, but I've never seen a board with 8 sockets. Keep in mind, dual core CPUs weren't a thing until years after NT4, so how did anybody get that to work?
I seen 6 cpu systems. Maybe a cluster?
I don't have a concrete example from the NT4 era, but I imagine that there were server boards that were perhaps expandable to multi-CPU with daughterboards. Analogous perhaps to this system from 2006: https://www.pugetsystems.com/featured/8-Proce … ors-32-Cores-56
(also slightly off-topic, I did try a while back NT4 Advanced Server in a virtual machine configured with 8 cores just for fun; worked well)

According to this list: ftp://ftp.hp.com/pub/softpaq/alphant/SP6_SUPP … PHA_SYSTEMS.TXT
And the table here: https://en.wikipedia.org/wiki/AlphaServer#Turbolaser_Family
already the 8400 series could have 14 CPUs...

Correct; let's not forget that x86 wasn't the only game in town even then.

I would go as far to say that there was actually a lot MORE diversity back then. x86 has been slowly eating away at the market share for years. The only other architecture that has increased in market share is ARM.
The Netserver LXr 8500 could take 8 Pentium III Xeons:

What was Windows NT 4.0E ?
eta: the Netserver LXr Pro8 could take 8 Pentium Pros: http://h20564.www2.hpe.com/hpsc/doc/public/di … emr_na-lpn12226
Is this too much voodoo?
Kay, Pretty cool tho. I just want to know if there was an 8 CPU x86 system around. I think Supermicro has one for sale.

The 8-way NT Server Enterprise Edition came out in September 1997 and HP was the first one out with this thing introduced at the end of the year. Up to four rack servers of 8 Pentium Pro's each.
First board that comes to mind is a TYAN S4985. http://www.tyan.com/archive/products/html/thu … dern4250qe.html
with the daughterboard, you had 8 sockets. I saw someone build one out of AMD 8x 8439 cpus (6 core @ 2.8g). It was running win7 like a champ. I think it was over on 2cpu.com
It is a mistake to think you can solve any major problems just with potatoes.
There were dual socket x86 motherboards around when NT4 came out? I have a quad slot2 P3 from 1998, people have mentioned dual PentiumPro's etc, so SMP was very much alive and kicking when NT4 came out.
Does any motherboard exist out there with more than 4 sockets? doubt it, that would be a very big motherboard, no point when you can utilise space perpendicular (i.e daughter cards to hold any extra circuitry/silicon/CPUage)? Love to see a pic if this is the case though. o.0
Multi CPU NT4 would have been marketed mainly for the Alphas imo, primarily due to the fact that, back then, you could count the number of programs commercially available on x86 that utilised SMP on two hands probably. Maya batch rendering was the only one I knew of (version 2.5, prob went earlier but that was the first version I used), there were no doubt others. While the instruction set of the compiled kernels and programs is different, both Alpha and x86 variants would utilise the same 'NT' technologies, so in theory an x86 version could support 8 CPU's, just like it's RISC sibling. There just weren't many of these systems about... too niche, and if you did find one, I doubt MS would have actually tested on an 8 CPU x86 system given the limited market for it, so stability might be an issue. Alphas on the other hand, are a different story, many Alphas with many CPUS around in 1997 so hopefully would have been widely tested.
Also NT4 is an OS for a shared memory architecture (parallel), not distributed, so blades and most clusters won't work with it. you need Windows CCS or HPC for clusters.
[EDIT:] correction, the Quad slot2 P3, is what I upgraded it to. It would have been Quad P2/450 when it came out in 1998. Apologies, my mem appears to be corrupted.

You should run HuMemtest on your brain to check for faulty addresses. 😀

I may be too late,but pair of 8220 opterons i got as diversity for my 1207 system were from 8 cpu 4 unit SUN server, the mobo itself does not have sockets and ram slots,each cpu on cpu card with own ram and such,looks like this:
