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.

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?

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.

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.

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

Permalink 18 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

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

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

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!

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.

Permalink 18 months ago
Cru3L139 submitter 2 Builds 1 point

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

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?

Permalink 18 months ago
Cru3L139 submitter 2 Builds 2 points

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

Permalink 18 months ago

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

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

Permalink 18 months ago
Cru3L139 submitter 2 Builds 1 point

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

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 :)

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

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

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

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.

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

Vorago 1 Build 1 point

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!

Permalink 11 months ago

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

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.
