You could overclock this like a madman, I believe if it's a good chip you'll get 4.8 or maybe even more, but now let's see,

Overclocking the GPUs would be a must man, look at ghose temps, they're so good.

Anyway awesome awesome awesome build, actually one that went with a watercooled build without going crazy overboard with like 64 gb ram and 10 ssds

How's that swiftech pump treating ya? Had one like it that broke down, but it was probably just a faulty unit, never had anything bad from swiftech.

Cru3L139 submitter 2 Builds 1 point 24 months ago

no luck with the CPU, won't boot above 4.6. 4.2 is fine for me as i don't really need one at 4.8. could do 4.4 but meh

GPUs are overclocked, stock is about 900mhz and i got them at 1150. got some issues when pushing them further. yeah the GPU temps are great indeed

really liking that pump, got it on 3 and it still is very quiet. the swiftech one gotta be my favorite d5

Your RAM is probably limiting your overclock, since with Haswell the higher speed you go past 1866 and the more sticks you have, the lower your overclocking potential.

You could try downclocking the RAM to 1866MHz but tightening the timings. That would probably do the trick. 4.6GHz is a pretty attainable speed for Haswell. For my 4770K it took me 1.225V to run stable at 4.6GHz, but that was with 2x8GB DDR3-1866. You might need more than 1.225 with 4 sticks of RAM @ 1866.

Since you're on water, temperatures are not going to limit you as much as voltage, and I'd say anything under 1.400V is safe in terms of CPU longevity, so you've got a lot of headroom!

Also, is 1150MHz your base clock or boost clock? If it's base clock, that's a pretty massive overclock, especially for a reference PCB/cooler O_O! My card would run Furmark and Kombuster stress tests just fine at 1180 base clock, but would crash at any base clock over 1014 when actually playing games...it's weird. Have you tried increasing your VRAM clocks?

Cru3L139 submitter 2 Builds 2 points 24 months ago

yeah i know pretty much all of that. as i don't need all of the cpu power with say 4.6 i rather have my ram running at 2133. but i might play around with it one day to see what my cpu can do.

sketch24 7 Builds 1 point 24 months ago

But if you know all of that, why would you sacrifice clock speed for memory speed? The memory speed only makes a difference if you are editing and even then the differences are minimal. You see real differences in performance between, let's say 4.2 and 4.4GHZ, but I doubt you'll notice any difference at all between 1866 and 2133.

Cru3L139 submitter 2 Builds 2 points 24 months ago

i don't need the higher cpu clock and i rather have it run cooler

LeMonarque 3 Builds 1 point 24 months ago

2133 increases your minimum framerates between 2-4 fps over 1866 in FC3 1080p maxed. So 1-3 at 1440p maxed. It's not something I've seen widely said, but memory speeds do help in gaming. It's just all they do is affect minimum framerates...

That said, I would definitely sacrifice RAM speed for CPU speed. 4.8GHz (which should totally be attainable under water) will give you far better gaming performance than 2133 RAM.

The only downside is that it takes time and effort to OC the CPU instead of leaving RAM at stock :P

xZora 1 point 24 months ago

What do you set the voltage to when you try to run at 4.6?

Cru3L139 submitter 2 Builds 1 point 24 months ago

well i tried different voltages, i know how overclocking works..

Hakumisoso 2 Builds 1 point 24 months ago

Have you adjusted the ring voltage?

Cru3L139 submitter 2 Builds 1 point 24 months ago

as stated before, i am not stupid

XIscottyIX 3 Builds 2 points 24 months ago

Now thats how u spend $4500 on a pc :) awesome job mate and thanks for sharing it with us!!

Cru3L139 submitter 2 Builds 3 points 24 months ago

thanks! i believe i spent even more than that. parts over here in germany are more expensive than the US prices listed here, i also built this like mid-july, so prices were higher than they are now

i think what i paid would be around $5500

ArrKayCee 2 Builds 2 points 23 months ago

This is a build of my dreams.

blaziecat1103 2 points 22 months ago

those beautiful stock coolers... sniff sniff

Cometballer 1 Build 1 point 24 months ago

I have dreams about building/owning a computer like this. Fantastic. +1 from me!

canders 7 Builds 1 point 24 months ago

Looks nice. Love to see more pictures.

Dave_6 1 Build 1 point 24 months ago

Amazing build! I'd love for mine to be like this one day.

DontUSASme 1 point 24 months ago

Moar pics!

Cru3L139 submitter 2 Builds 1 point 24 months ago

i'd love to take more pictures although the whole thing is quite heavy and just sits there for now. i had quite some trouble getting that PC where it is now so it's not gonna move for a while :P. i'd have to put it somewhere else to take proper pictures which isn't going to happen at the moment, sorry

thanks tho!

spindrjr 1 Build 1 point 24 months ago

I can imagine. My recent build is very similar to this, but with extra hard drives adding weight as opposed to WC loops (so yours is probably even a bit heavier). I ended up using a Cosmos 2, but was considering a 900D. After getting everything in it, it was near the limit of my strength to lug it up the stairs even with handles on the top.

Did you move this up or down stairs at all? Did you move it by yourself? I don't think I could safely move my build by myself up or down stairs if it was in a 900D.

Cru3L139 submitter 2 Builds 1 point 24 months ago

no stairs, built it upstairs as i knew that wouldn't be possible. i actually only needed to move it like 2 meters, but even that was a pain in the *** as i couldn't just slide it in place due to very grippy rubber feet

spindrjr 1 Build 1 point 24 months ago

Haha. Good planning ahead!

Marcus_CA 1 point 24 months ago

Did you have to import those Alphacool rads? I've building similar but with 5 rads. It's around the 550$ CA just for 5 rads to have them imported from EU.

Cru3L139 submitter 2 Builds 1 point 24 months ago

i'm from Germany so no

ExcaliburVII 1 point 24 months ago

Wow, this is epic. There really needs to be more awesome builds like this on PCPartPicker.

Cru3L139 submitter 2 Builds 1 point 24 months ago

thanks!

Cru3L139 submitter 2 Builds 1 point 24 months ago

found more pictures!

SIRmisterD 1 point 24 months ago

God dang! That is one super computer!

I do have one question:

Why did you go with 4 x 4GB sticks of RAM? Why not 2 x 8GB to save room for later upgrades?

Cru3L139 submitter 2 Builds 2 points 24 months ago

imo 4 sticks look better. pretty sure i won't need more than 16gb so no need for upgrades

SIRmisterD 1 point 24 months ago

Makes sense then. Just a thought that popped into my head. :) Nice work!

UntamedShadow 1 Build 1 point 24 months ago

One question why not go with the Two 480mm NexXxoS raditors instead of 360mm? Also which radiators are you using UT60 or Monsta?

But very nice build

Cru3L139 submitter 2 Builds 1 point 24 months ago

i wanted to get 480s but i didn't get them anywhere, so got 360s instead. they do a great job as well. all rads are UT60s

thanks!

KeeblerXII 1 point 24 months ago

What fittings are those? they look really nice

Cru3L139 submitter 2 Builds 1 point 24 months ago

should be those http://www.aquatuning.de/product_info.php/language/en/info/p13970_16-10mm-Anschraubt-lle-G1-4---ger-ndelt---black-matt.html obviously i don't only have straight ones, but they got those in 90 and 45 as well

KeeblerXII 1 point 24 months ago

Awesome, I have been looking for some good fittings. Thanks

RyneSmith 7 Builds 1 point 24 months ago

This is awesome, props for putting together such an awesome system.

Sucks though that you couldn't get the CPU higher but like you said you only need 4.2.

I'm sure this will treat you well :)

+1 and more if I could

This looks sexy lol :D

DjArtifact 1 point 24 months ago

+1 for the raystorm, I love XSPC blocks.

Cru3L139 submitter 2 Builds 1 point 24 months ago

love them, thanks!

DylanSLC 1 Build 1 point 24 months ago

So one pump puts it through three rads and the rest of the system? That's freaking awesome!

Cru3L139 submitter 2 Builds 1 point 24 months ago

yes. it's an amazing pump though

mvickers89 1 Build 1 point 24 months ago

You future-proofed the hell out of this one. Nice work. A+

TheOne 1 point 24 months ago

Beyerdynamic

Rayyo 1 point 24 months ago

not sure why this is a supercomputer, it's quite standard.

Marcopolo 1 point 24 months ago

uuuu Mr. Aesthetics :=)))

Rayyo 1 point 24 months ago

could a 550w psu work for a single gtx 780?

Cru3L139 submitter 2 Builds 2 points 24 months ago

would be a bit tough.. don't cheap out on the PSU. when you got the money to get a 780 might as well sped 20 bucks more on the PSU

Rayyo 1 point 24 months ago

What's the worst that could happen if you cheap out on the PSU?

Cru3L139 submitter 2 Builds 2 points 24 months ago

it could fry your whole PC

Rayyo 1 point 23 months ago

would a 850w work?

Cru3L139 submitter 2 Builds 1 point 23 months ago

if its a good brand, yes

Rayyo 1 point 24 months ago

why do you recommend 780w when you yourself use 860w?

Cru3L139 submitter 2 Builds 1 point 24 months ago

i meant gtx780, not 780w

N2C3K 1 point 23 months ago

Did you have a budget on this build?

Cru3L139 submitter 2 Builds 2 points 22 months ago

i intended to spend $2500, but then i wanted that, and that...

LookTopHats 2 Builds 1 point 22 months ago

How is the barracuda?

Cru3L139 submitter 2 Builds 1 point 22 months ago

no issues so far. not loud or producing much vibration

LookTopHats 2 Builds 1 point 22 months ago

Great, thanks

Xiocious 1 Build 1 point 22 months ago

If I got this case and a 480mm rad for the bottom would I be able to put fans on both sides?

Cru3L139 submitter 2 Builds 1 point 22 months ago

depends on how thick the rad is. up to 60mm, yes

Xiocious 1 Build 1 point 22 months ago

Same for the top? Also with that PSU could you fit 4x 120 fans on both sides of bottom?

Cru3L139 submitter 2 Builds 1 point 22 months ago

top depends on motherboard but most likely yes to both

Xiocious 1 Build 1 point 22 months ago

Okay. Thanks!

ImElkay 1 Build 1 point 18 months ago

Push pull config really doesn't help much. Maybe a degree or 2c

Yevgeniy_Onegin 1 Build 1 point 22 months ago

I'm doing a similar build. Is 860 watts enough? I have 2 choices: 1. AX860i 2. AX1200i

Cru3L139 submitter 2 Builds 1 point 22 months ago

860w is enough, no problems at all so far

blaziecat1103 1 point 22 months ago

Nice anti-corrosive gummy bears!

Avalancer 1 point 21 months ago

What's that clock called?

Chuk 1 point 21 months ago

What to do with the remaining PCI slots?.....mmmmmm........

athanagames 1 point 21 months ago

How's the SSD?

Cru3L139 submitter 2 Builds 1 point 21 months ago

does its job well. can't complain

nasirdude3211 3 Builds 1 point 21 months ago

One word... AMAZING!

yoshi1337 1 point 20 months ago

Very similar to the build im currently working on

bugattikid2012 1 point 19 months ago

Quick question: Why the heck do you need so many fans!?!?!??!?!! You're already water cooling, nothing is going to get THAT hot lol!

Cru3L139 submitter 2 Builds 1 point 19 months ago

all rads are 60mm thick. i run my fans at 7v so they are very quiet

bugattikid2012 1 point 19 months ago

I still don't see why you need that many regardless. I'd guess 4 of those would still be overkill, but I can't confirm that. Not hating just really curious lol.

Cru3L139 submitter 2 Builds 2 points 19 months ago

yeah it's a bit overkill. could ditch the 240 rad completely but i wanted to build in a 900d and without it the case would look a bit empty

ImSoSpcl 1 point 18 months ago

i like your build man looks nice and clean

Vorago 1 Build 1 point 17 months ago

Hi, amazing build you have here! I just have a question about the benchmarks you posted - what exactly is the difference between the two shots besides the screen resolution? In settings the 1080p is preset to "Extreme HD" and the 1440p is set to "Custom - Ultra". Is the "Ultra" setting lower than "Extreme HD"? ...because the additional 5-6 extra FPS minimum despite having higher resolution is blowing my mind right now.

Thanks in advance for any info!

Cru3L139 submitter 2 Builds 1 point 17 months ago

There is no preset for 1440p. It's basically the same, everything maxed

HueyTheGod 1 Build 1 point 17 months ago

Amazing build man! Shame you bought those 780's for the price of a 780 Ti :/

Cru3L139 submitter 2 Builds 1 point 17 months ago

well i bought them right when they were released. ofc they are cheaper now. that's how things work in this world. can't complain

HueyTheGod 1 Build 1 point 16 months ago

Yeah, I suppose. Just a shame. That's why I don't want to buy 3 27" monitors - 1440p 27" monitors will replace the average 1080p in a year or so.

kyrapoq 1 point 7 months ago

Nice build. Did you have to do the BIOS update to the mobo?

MrMOABy 1 Build 0 points 24 months ago

This looks like something I plan on having in a couple years cept it will have titans, 7990s, or 780s.

Cru3L139 submitter 2 Builds 5 points 24 months ago

"in a couple years" you'll have whatever comes after 9970s or 980s

MrMOABy 1 Build 1 point 24 months ago

yeah i know that haha forgot to put in the equivalent of titans, 7990s, or 780s.

zlogs 1 Build 2 points 24 months ago

Titans are a waste of money now.
