Build

Core i9-7980XE Workstation

by bwells46

Description

I use this for casual gaming and for work with medical imaging, virtual machines, and artificial intelligence medical image modeling.

The CPU is overclocked to 4.5 GHz on all 18 cores using 1.1250 volts for temperature reasons. I might be able to lower the voltage a little further, but temps never get above 85 under 100 percent load and the system is stable, so there's not much point.

I'm waiting for my replacement set of 64 GB DDR4 to bring the total RAM to 128 GB. One of my packs had a back stick, so only four are installed right now.

The small screen is a GeeekPi 5 inch screen for monitoring temps and voltage. I’m waiting on an acrylic mount, and then I’ll be permanently mounting it inside the case.

The cable management needs work, but that isn't likely to change anytime soon.

UPDATE 7/22/2018: Successfully got a 4.6 GHz all core overclock running with stable framerates on 3DMark - http://www.3dmark.com/tsst/179157.

Your wallet must've commited suicide.

if he's doing work that involves "... medical imaging, virtual machines, and artificial intelligence medical image modeling."

I'm gonna guess he makes serious cash lol

bwells46 submitter 1 Build 14 points 18 months ago

It sucked going through it, but two master's degrees and four years of medical school does pay off eventually.

So true

"And yes, I know I could have used Threadripper"

Threadripper has a 10% lower IPC and limited clockspeed, as well as 2 less cores. Yes, $2,000 for 2 extra, slightly faster cores probably isn't practical, but it's still better than Threadripper. This is a very nice build. +1

you are an intel fanboy?

BBearPvP 2 Builds 6 points 18 months ago

Check out my completed builds. My main build's a Ryzen system. :P I'd hardly consider myself an Intel fanboy.

Come to think of it, I'm not really a fanboy of anyone. I just like the best company that offers the best price/performance ratio. That's just been AMD and NVIDIA the last year or so.

lallo29 1 Build 1 point 18 months ago

Good build :) For me, 1950x is a little better, because you have 16 core and 32 thread for 1000 euros... if you want an i9 7980xe you have to pay at least 2000 euros for 2 core extras

BBearPvP 2 Builds 1 point 18 months ago

Well, you can overclock it up to 4.7 GHz, which is effectively 700 more MHz than you can get out of the average 1950X. 700*16 is effectively 11.2 more GHz, plus the extra 2 cores, which adds up to around 20.6 more GHz effectively (yes, I'm aware it doesn't work that way). But that's basically like the equivalent of 5 more cores rather than 2. Maybe my ideology is flawed. :P

lallo29 1 Build 1 point 18 months ago

For me and is better, because a 1950x costs only 1000. But anyhow, if you need a computer with these cpus, you don't have budget problems

adventureguy 2 Builds 5 points 18 months ago

Lmao when your CPU is more expensive than my entire system....

Unreal. That must be some serious work to justify this. Nice build though!

thebream 3 points 18 months ago

This things insane, is it tax deductible?

bwells46 submitter 1 Build 4 points 18 months ago

It absolutely is.

thefowles1 2 points 18 months ago

Newegg page for the CPU states the supported memory is only DDR4-2666, but the RAM you ordered is far higher than that. Does that mean the RAM will need to be underclocked to work with it? Genuine question, as I’m still learning how compatibility works.

bwells46 submitter 1 Build 3 points 18 months ago

Nope. XMP mode will allow you to use it at full speed.

thefowles1 1 point 18 months ago

Wow, that’s crazy impressive. Thanks for the reply.

thepanicoffice 1 point 17 months ago

Is XMP mode any extra strain though? Will it run a lot hotter? I'm making RAM decisions now, for a similar build to yours with the same board, same GPU and i9 7960. Just wondering if I should stick to 3200, or go higher as you did.

bwells46 submitter 1 Build 2 points 17 months ago

No real strain that I can see, but I also notice little to no difference with 3466 v 3200.

marksman 4 Builds 2 points 17 months ago

Hey man, I'm gonna copy this build. I just wanted to know why all of the 7980xe Rampage Extreme VI builds on here have 1500w power supplies. Is it completely necessary or will I be okay with an EVGA 1200 Supernova? Thanks man

bwells46 submitter 1 Build 2 points 17 months ago

A 1200W should work, but a 1500 will be better for future expansion.

marksman 4 Builds 1 point 17 months ago

Thanks!!!

thepanicoffice 1 point 17 months ago

Thanks, I've been agonizing over the same question! Keep going back and forth between 1200 and 1500, wondering if i went 1500 that I might sacrifice efficiency. Still figuring it out!

marksman 4 Builds 2 points 17 months ago

I ended up going for a 1600 T2 Evga haha

thepanicoffice 1 point 16 months ago

Nice! I almost went 1600 too, but stuck with AX1500i

HaltCitizen 1 point 18 months ago

Yes, I know THIS IS AN AWESOME BUILD

Xyxer 1 point 18 months ago

Please post some benchmarks, this is the most powerful CPU I have ever seen on PCPP! Good job!

bwells46 submitter 1 Build 1 point 18 months ago

I posted some benchmarks in the images for you. Realistically, the numbers would probably be a little higher, but I have some software running in the background.

Xyxer 1 point 18 months ago

Wow...

mcconkeymike 4 Builds 1 point 18 months ago

That's one powerful PC you built and it actually sounds like you'll be utilizing all of those cores and whatnot with what you are doing, but I do have one burning question....How in the name of everything holy does one justify $1600 on RAM??? I understand you have and probably need a lot for what you will be doing, but the Dominators, while nice, are seriously expensive for what you get, not to mention, $1600 for RAM! Now please, don't be offended, I am jealous of the incredibly powerful system that you have built, I personally just have a hard time justifying something like that.

bwells46 submitter 1 Build 1 point 18 months ago

I use a RAM drive for modeling, so it’s just convenient to have a lot.

ItsJashun 1 point 18 months ago

Nice PC

cubexbaen 1 point 18 months ago

wow... now that's a system that could last for ages LOL

Axolotlotlotl 1 point 18 months ago

Question any particular reason for going with the Rampage instead of the PRIME X299-DELUXE or TUF X299 MARK 2, or one of the few other x299 motherboards?

bwells46 submitter 1 Build 1 point 18 months ago

Asus has a good reputation, and they tend to put everything into their Extreme boards. In this case, it was 10G Ethernet onboard which saves a PCIe slot for future use.

ElmoKajaky 1 point 18 months ago

How did you get that motherboard? It doesn't seem to be in stock anywhere (even at B&H it says "Preorder").

bwells46 submitter 1 Build 1 point 18 months ago

I pre-ordered on Amazon when it was first available and got it late September.

Drayth 1 point 17 months ago

I started assembling my build using this board yesterday, but had to stop due to not being able to mount my Kraken x62 AIO, which you appear to also be using. 3 of the 4 holes needed in order to mount the back plate are filled in on my MB, so I can't push the screws through to the BP. Did you hit this same problem?

marksman 4 Builds 1 point 17 months ago

Hey there, is your 7980xe delidded?

bwells46 submitter 1 Build 1 point 17 months ago

No. I can hit 4.5 GHz on all cores with decent temps without delidding. That’s good enough for me.

birdman9411 1 point 16 months ago

Amazing.

Trinescity 1 point 15 months ago

Now that the Titan V is out, do you plan on replacing your 1080tis with one?

bwells46 submitter 1 Build 1 point 15 months ago

I’m not convinced the performance is worth $3000. I’ll wait for the technology to mature more first. The SLI setup I have now is doing the job pretty well.

ntk95 1 point 14 months ago

Did you delid your 7980XE and use liquid metal??

bwells46 submitter 1 Build 1 point 14 months ago

No. I have a stable, all core overclock to 4.5 GHz without delidding. I’m happy with this.

le__render 1 point 14 months ago

Hi,

Just wanted to ask a quick question. I am also running the 7980XE on a Kraken X62 but get bad temps at an overclock of 3.8GHz over 85C.

How do you manage to get 4.5GHz and running mid 85s max? I can only think there's something wrong with my Kraken because this is the second 7980XE i've gone through after going through an exchange.

bwells46 submitter 1 Build 1 point 14 months ago

Don’t just overclock it. You’ll run into thermal limits. Instead, you also need to lower the core voltage. For me, an offset if -0.07 worked for an all-core of 4.5.

le__render 1 point 14 months ago

thanks so much for your quick reply! I will look into that!

rarzer 1 point 14 months ago

Nice build! I´m thinking about getting a 7980XE as well for my work.

I´m curious about your Cinebench score of 4109cb - Was this at 4.5 GHz? I find it quite low compared to trend results at HWBOT, it should be on the 4400-4500 range.

bwells46 submitter 1 Build 2 points 14 months ago

I ran that after I first built the system, and I think I had some things running in the background so that probably lowered the score. I haven’t really run it since for comparison.

iMoonTiger 1 point 13 months ago

"Workstation"

Yeah ok

rl3058 1 Build 1 point 12 months ago

Any issues with the Pioneer BDR-211UBK optical drive?

bwells46 submitter 1 Build 1 point 12 months ago

Nope, other than I never use it. I used it once to rip a DVD and have not touched it since.

rl3058 1 Build 1 point 12 months ago

Thank you

yashar91 1 point 10 months ago

The RAM you have is the CMD64GX4M4B3466C16. Under amazon description and corsair website it says its compatible with Intel 100 Series. There are other 4 x 16 gb sticks I think running at 3200 that show it's compatible with x99 or x299 Intel series. So, my question is that have you had any compatibility issues with your current RAM sticks with your Asus Rampage VI Extreme x299 MOBD? Any BIOS issues or overclocking. Does the drivers install all fine? The Corsair website has the 4 sticks you installed as only compatible with intel 100 series. I just want to make sure that's not 100% true and it can be used with other MOBDs including the one you're using.

Thank you so much for your replies

bwells46 submitter 1 Build 1 point 9 months ago

Asus has it listed as compatible in their motherboard manual, though in a 64 GB configuration. My 128 GB is not technically supported, but I have had no issues with it.

sdawg96 1 point 9 months ago

"casual gaming" dude I wish I had 8 and a half thousand dollars to spend on a "casual gaming" rig. Can I have your job...please?

Outlaw_123 0 points 18 months ago

Damn, cable management must have been hard af. Also, no hdd? I know 2 tb of ssd is good enough, but maybe a 3 or 4tb hdd? Idk, that's your choice to make. Nice build!

Note: That must've cost your kidney

bwells46 submitter 1 Build 1 point 18 months ago

I use a QNAP TS-453A with four 8 TB drives in a RAID-5 for my primary storage. Work files also get backed up to a 8 TB Synology DS916+ in RAID-5.

bwells46 submitter 1 Build 1 point 18 months ago

I’ve built several computers and cable management is one thing I’ve never managed to really get good at. My systems usually look like a mess inside.

Techmaster123Xd 1 point 18 months ago

So funny

JudtheBud 0 points 17 months ago

Picture # 3, theres a macbook. How dare you.

bwells46 submitter 1 Build 1 point 17 months ago

Lol, there’s also a Xbox One S and a PS4. I don’t discriminate.

JudtheBud 1 point 17 months ago

Xbox one S and PS4 are fine since most people have it for the exclusive games and my friends have them to play with each other.

Techmaster123Xd -3 points 18 months ago

128gb of ram is overkill. But nice build!

FurryJackman 3 Builds 2 points 18 months ago

Not when he's running medical imaging (which is like Solidworks in terms or resource use) and virtual machines.

bwells46 submitter 1 Build 1 point 18 months ago

I use it mostly for work, but I do play some games on the side.
