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 12 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 12 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 [6 Builds] 0 points 12 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 12 months ago

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

 
 
LeMonarque [3 Builds] 1 point 12 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

 
 
sketch24 [6 Builds] 1 point 12 months ago

You have a benckmark or link? I don't see it mentioned much, because it is neglible differences in FPS for most games. Another bench

If you are running at 40-60 FPS, is 1-4 FPS noticeable? And is it within the margin of error of doing benchmarks?

 
 
LeMonarque [3 Builds] 1 point 12 months ago

Here is a link

Do not confuse average FPS benchmarks with image smoothness. It's a very important factor and a very good indicator, but it's not the whole picture.

First of all, those benchmarks are reporting average FPS. Memory speeds improve minimum FPS, which are the low swings you can periodically get in games. Minimum FPS by nature is not represented well in benchmarks of average FPS. An increase of 10 minimum FPS could result in very little change in average FPS depending on your maximum FPS and the test method in-game (ie, how often is the tester viewing graphically intensive things in-game? Recorded min, max, and average FPS do not have equal weighting). The lower the swing, the more of an impact you get visually, which affects the smoothness of the game.

So in terms of minimum FPS, where the % increase per frame is much higher than the % increase per frame for maximum or average FPS, then yes, 1-4 FPS is noticeable. You would notice a difference between 15 and 20 FPS, because those are minimums. You would not notice a difference between 60 and 65 FPS (example of average) or 90 and 95 FPS (example of maximums).

But that said...

It's totally a waste of money for the average user. But for those that have cash burning holes in their pockets and need to get it off their bodies ASAP, then memory speed can be part of an upgrade. It's also an option for people operating on a budget and have $30-$40 leftover. There's not much you can do with that except increase memory speed (assuming you don't sacrifice higher speed for extremely looser timings).

Also, the example of 1-4 FPS is assuming you are running games with a "non overkill" setup. For example, a GTX 760 at 1080p or a GTX 780 at 1440p. Getting 200 average fps at 1080p would obviously result in higher differences in minimum framerate.

 
 
sketch24 [6 Builds] 0 points 12 months ago

Did you read both the links I posted? One uses a second by second frame time analysis and the other shows minimum frame rates as well as averages. The toms hardware article mentions that lags in frame-time (the choppiness) seem like they are due to graphics performance rather than memory performance.

As for your link, I'm not sure how much I would believe a forum link. I'm sure the user has a lot of experience, but in the end, he's just some user somewhere. You don't know his methodologies or how reliable they are. Maybe there is a subjective difference, but I'm not going to go by it unless it's also supported by some review sites.

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

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 12 months ago

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

 
 
Hakumisoso [2 Builds] 1 point 12 months ago

Have you adjusted the ring voltage?

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 12 months ago

as stated before, i am not stupid

 
 
Hakumisoso [2 Builds] 1 point 12 months ago

I was wondering for myself, wondering how high you pushed it.

 
 
XIscottyIX [3 Builds] 2 points 12 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 12 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 [1 Build] 2 points 11 months ago

This is a build of my dreams.

 
 
blaziecat1103 2 points 10 months ago

those beautiful stock coolers... sniff sniff

 
 
Cometballer [1 Build] 1 point 12 months ago

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

 
 
canders [6 Builds] 1 point 12 months ago

Looks nice. Love to see more pictures.

 
 
Dave_6 [1 Build] 1 point 12 months ago

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

 
 
DontUSASme 1 point 12 months ago

Moar pics!

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 12 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 12 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 12 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 ass as i couldn't just slide it in place due to very grippy rubber feet

 
 
spindrjr [1 Build] 1 point 12 months ago

Haha. Good planning ahead!

 
 
Marcus_CA 1 point 12 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 12 months ago

i'm from Germany so no

 
 
ExcaliburVII 1 point 12 months ago

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

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 12 months ago

thanks!

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 12 months ago

found more pictures!

 
 
SIRmisterD 1 point 12 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 12 months ago

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

 
 
SIRmisterD 1 point 12 months ago

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

 
 
UntamedShadow [1 Build] 1 point 12 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 12 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 12 months ago

What fittings are those? they look really nice

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 12 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 12 months ago

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

 
 
RyneSmith [7 Builds] 1 point 12 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

+1 for the raystorm, I love XSPC blocks.

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 12 months ago

love them, thanks!

 
 
DylanSLC [1 Build] 1 point 12 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 12 months ago

yes. it's an amazing pump though

 
 
mvickers89 [1 Build] 1 point 12 months ago

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

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

 
 
Marcopolo 1 point 12 months ago

uuuu Mr. Aesthetics :=)))

 
 
Rayyo 1 point 11 months ago

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

 
 
Cru3L139 [Submitter] [2 Builds] 2 points 11 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 11 months ago

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

 
 
Cru3L139 [Submitter] [2 Builds] 2 points 11 months ago

it could fry your whole PC

 
 
Rayyo 1 point 11 months ago

would a 850w work?

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 11 months ago

if its a good brand, yes

 
 
Rayyo 1 point 11 months ago

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

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 11 months ago

i meant gtx780, not 780w

 
 
N2C3K 1 point 10 months ago

Did you have a budget on this build?

 
 
Cru3L139 [Submitter] [2 Builds] 2 points 10 months ago

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

 
 
LookTopHats [2 Builds] 1 point 10 months ago

How is the barracuda?

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 10 months ago

no issues so far. not loud or producing much vibration

 
 
LookTopHats [2 Builds] 1 point 10 months ago

Great, thanks

 
 
Xiocious [1 Build] 1 point 10 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 10 months ago

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

 
 
Xiocious [1 Build] 1 point 10 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 10 months ago

top depends on motherboard but most likely yes to both

 
 
Xiocious [1 Build] 1 point 10 months ago

Okay. Thanks!

 
 
ImElkay [1 Build] 1 point 6 months ago

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

 
 
Yevgeniy_Onegin [1 Build] 1 point 10 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 10 months ago

860w is enough, no problems at all so far

 
 
blaziecat1103 1 point 10 months ago

Nice anti-corrosive gummy bears!

 
 
Avalancer 1 point 9 months ago

What's that clock called?

 
 
Chuk 1 point 9 months ago

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

 
 
athanagames 1 point 9 months ago

How's the SSD?

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 9 months ago

does its job well. can't complain

 
 
nasirdude3211 [3 Builds] 1 point 9 months ago

One word... AMAZING!

 
 
yoshi1337 1 point 8 months ago

Very similar to the build im currently working on

 
 
bugattikid2012 1 point 7 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 7 months ago

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

 
 
bugattikid2012 1 point 7 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 7 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 5 months ago

i like your build man looks nice and clean

 
 
Vorago [1 Build] 1 point 5 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 5 months ago

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

 
 
HueyTheGod [1 Build] 1 point 4 months ago

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

 
 
Cru3L139 [Submitter] [2 Builds] 1 point 4 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 4 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.

 
 
MrMOABy [1 Build] 0 points 12 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 12 months ago

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

 
 
MrMOABy [1 Build] 1 point 12 months ago

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

 
 
zlogs [1 Build] 2 points 12 months ago

Titans are a waste of money now.
