Extraordinary performance with dual Intel® Xeon® CPU overclocking
Dual Intel® Xeon® CPU overclocking, pushes the power processing power beyond the extreme

ASUS WS C621E SAGE breaks performance barriers, giving you the capability to overclock dual Xeon® CPUs. With its unique BIOS mechanism dedicated to boosting CPU performance, WS C621E SAGE can deliver incredible system speed.

Alright, so let's just set aside that fact that with this board it's possible to build an overclock-able 112 thread computer in one box.

Today you can buy a single 8 core Xeon Skylake-X with HT for $260 on ebay. Which would equal 32 overclocked threads for $520 + the price of this board(~$1000)

Would that combo be better than buying a 7900k?

You can pick up these 20-28 core cpus for $1000-$3000 on ebay. It's crazy how the second hand market gets decimated for this kind of gear.

I'm sure the 8-core skylake-x im seeing is some kind of engineering sample for a xeon plat/silv/gold.

This was always a manufactured limitation that intel did on purpose to jack up the prices of their Extreme Edition processors.

I guess this move with asus is Intel's way to get competitive with Threadripper and EPYC.

Anyone know if EPYC can overclock at all?

Yeah, what's scary is that they've been out for well over a year. I think three systems using Skylake-SP made it onto the TOP500 list an entire year before it was officially launched.

I imagine most of the cheapo chips are engineering samples. I'm not sure how much I would trust one of those on a very new platform. Intel totally redesigned the cache, plus it's a new architecture over Broadwell and that tends to have some fun problems to sort out.

4.5GHz 18 cores is already pushing 400W. No way you'll be able to sustain any reasonable clocks on all cores.

These would be best with Xeon Silvers, coupling few, fast cores with ~250GB/s throughput over 12 channels.

but what about 4ghz+ on a pair of 4108 , this board + a pair of this cpu is cheaper than a 16 cores Skylake-X

So it needs 2000 watts for the cpus alone if you go on full 56 cores overclocking

,a separate psu for the gpus. And probably a nuke reactor. Gonna be cool to see limits of the latest high-core count cpus though.

Great Scott... Hope the chips are soldered

How about, if you're an American, you'll need to use two breakers or a 220V outlet, because a standard 15A breaker would trip as soon as you fired up any remotely demanding software.

Cooling the beast would also be a challenge, though the die and IHS are large enough that they might not be quite as hard as LCC or HCC Skylake-X. They probably would be but there's a sliver of hope.

Won't that depends on how well you can actually overclock a xeon? Since they are mostly locked, we have no idea how much you can actually push them on this system.

But that 16 core can be pushed decently beyond 4ghz. So any program scaling with single core performance, will mostly run better on the single CPU solution.

Sadly no, because every board Epyc fits in has the bios locked down for server board stuff.
Sad because a 12 core Epyc costs the same as the top 8 core TR. If you could OC the Epyc then it would be selling like crazy.
Thats another reason AMD rearranged the pin layout of their socket to make TR and Epyc incompatible between boards.

Gee wizz, A server board locked down for server stuff, Who would of thunk it!

I had a dual Xeon workstation back in 1998 LOL ... seriously ... now I just roll with the 6700K ... but the workstation days were sure fun ...

So what kind of overclocking are we actually talking about? Raise BCLK to 103 MHz?

Straps? Unlocked multiplier?

Someone on HWbot already did something like this with a supermicro board. 2x8176M processors at 3800mhz ( 2 waterblocks for the cpus and watercooled ram )
2x10000 USD + 5000 USD for 2 cpus + motherboard ( not including the ram / power supply / and his own custom waterblocks )

This ASUS board is going to have way better vrms than that supermicro board so it should overclock higher?

Who's going to get 2x8180 or 2x8180M?

http://forum.hwbot.org/showthread.php?t=173528

The die is increased and the IHS area too ( 7740X at 60C 4500mhz x4 cores + 2666mhz ram vs 7700K at 65C and 4500+4400+4400+4400mhz + 2400mhz ram )

Do any of the LGA 3647 Xeons have unlocked multipliers?

Just need to use a 20A plug instead... That gives you 2400W.

So two dedicated 20A runs, one for your CPU power supply, other one for the GPU power supply and monitors and speakers :p

Since when were Xeon chips unlocked?

Yes with the multiplier locked, and the Turbo frequencies for the 8176M are 3.8 GHz, which was also the overclock frequencies of the earlier mentioned xeon OC. The marketing of this board seems to suggest incorporation of MCE into WS boards...
