Description

Purpose:

This is my main computer for everyday use:

  • Anime
  • Mild Gaming
  • HPC Programming in C/C++.

This is a drop-in replacement for my FX-8350 rig which I built last year. Compile times on the FX-8350 @ stock were painfully long. Initially, I considered re-purposing and switching to my i7 4770K @ 4.0 GHz, but compile times were surprisingly just as bad. (I suspect that it has to do with the FX-8350 having 8 integer cores while the 4770K only has 4.)

I've been craving for a high-end build for a very long time and I'm not at all confident that the Skylake Xeon will come out before 2016. Therefore I finally decided to let loose my first no-holds-barred rig since 2008. This build cuts compile times in half and lets me create large ram drives to quickly test code that is meant for disk.

Inherited/Cannibalized Parts:

  • WD Green 4TB
  • 4 x 1080p monitors. (2 x 27 in. + 2 x 24 in.)
  • Keyboard/Mouse + Speakers

Notes:

  • Don't use Patriot memory on this motherboard. Not only are they not vendor-qualified, they aren't even stable at 2166 MHz. I made this mistake and had to wait until after Christmas to replace the memory.
  • The Corsair memory advertises as 2400 MHz. But there's an XMP profile for 2666 MHz - which seems to work. Okay, I'll take that...
  • The Gigabyte GTX 750 Ti is one of the only inexpensive gaming video cards I've found that supports 4 monitors.

The CPU temperatures vary by up to 10C between the different cores with the hottest one reaching 70C under Prime95 small FFTs at room temperature. The even cores are hotter than the odd cores. Which probably means I didn't apply the thermal paste evenly (it's a really big chip). Whenever I get the time, I'll probably go back and reseat the water block.

Edit 1-10-2014:

Redoing the thermal paste and reseating the water block didn't help at all. Neither did applying differential pressure on the mounting screws. Oh well...

Final 24/7 Overclock Settings:

  • Base Clock: 100.1 MHz
  • CPU Frequency: 100 x 40 = 4.0 GHz (all cores)
  • CPU Cache: 100 x 36 = 3.6 GHz
  • Vcore: Offset +0.100 (~1.214v under load)
  • Vcache: Offset +0.150 (~1.125v under load)
  • DRAM Frequency: 133 x 20 = 2666 MHz
  • DRAM Voltage: 1.35v
  • Memory timings manually set to: 14-16-16-35

The memory settings are done manually because the XMP profile for 2666 MHz sets the base clock strap to 125 which seems to cause problems when putting the computer in standby. So I turned off XMP, set the base clock back to 100 MHz, and manually entered all the memory settings that XMP would have set.

This overclock is AVX2 stable with 100 MHz headroom for both CPU and cache frequencies. I need it to be since I do HPC programming and I write and run code that uses AVX/AVX2.

Watching anime with a 5960x..? +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1 +1

Sed8Op8 3 Builds 3 points 31 months ago

My co worker sprang for the 5960x on his new WS. When he was putting his TIM on he made the same mistake of just using a pea sized glob. I had watched a video on the 5960 and told him to look at the size of the chip the Die underneath must be freaking HUGE. Anyways he was experiencing high temps he went back and reseated this time using one blob in the middle and a small one in each of the four corners. His temps dropped 5-10c he was surprised the temps didn't drop more but it's got a fairly high TDP and he has it OC'ed to 4.1@1.25v with a H105 I told him its going to run hot regardless but his temps haven't gone over 70c now and I figured that's pretty normal. Anyways very nice build. I know you don't game but the gamer in me sees that CPU and I want to see a bad *** GPU paired with it. It seems in your case though there's not really any need. Congrats and I hope she treats you well. RAM Disk with 64GB of some fast DDR4 must be pretty sick!

mysticial submitter 5 Builds 1 point 31 months ago

Thanks! You're definitely not the first person to point out that the video card is kinda... crappy. I haven't done any extreme gaming in a long time so I couldn't really justify getting a higher-end video card.

About the TIM, yeah, I think I'm gonna be reseating it the next time I open up the machine... :)

Right now I'm at core/cache 4.0 GHz/3.75 GHz with vcore/vcache 1.21/1.21. These voltages are actually stable for 4.125/3.875 GHz, but I always leave a bit of headroom.

Not every pc built is for gaming. Why cant people understand that. lol

Raimei 1 point 30 months ago

Yeah, man. Not every PC should be treated like a console, because its above and beyond that. Sometimes I never got the point of budget GPUs placed in rigs that have CPUs that are Xeon 8-12 cores, but when it came to rendering, the it makes sense.

tabascosauz 3 Builds 1 point 31 months ago

+1. Very nice to see some truly high-end hardware inside the C70. 5960X @ 4.0GHz? Yes please.

mysticial submitter 5 Builds 1 point 31 months ago

Of all the rigs I've ever built, this one is by far the easiest to overclock. (With the 2600K coming in at second.) Never have I been able to instantly do +33% overclock without really touching the voltages.

There's a lot of room left. But unlike my other rigs, I'm not gonna try to push it. At 4 GHz it draws around 280W under load - which is double the TDP. It's one thing to burn or degrade a $300 CPU. It's another to burn this one.

Nice description, Nice Pictures, Nice Parts, +1 for Keyboard.

KingSaif 1 Build 1 point 31 months ago

Holy...a $3100 build with a 750 Ti? With that kind of budget you might as well have a 144 HZ/1440P monitor with AT LEAST a GTX 970/980.

Tommo791 2 points 31 months ago

Agreed, definately consider pushing 1440p or 4k

awepicness 1 Build 1 point 31 months ago

He does have a $1000 CPU and 64GB of ddr4 memory

ThatsPoorlyDrawn 3 Builds -1 points 31 months ago

4k on a 750ti? And he only needed the 750ti for the multi monitor setup, apparently not for major gaming.

Tommo791 1 point 31 months ago

4k or 1440p monitors don't have to be used for gaming.. They do look incredibly crisp when doing other tasks

[comment deleted]
Tommo791 1 point 30 months ago

That is fair enough, but subjectively speaking it doesn't bother me ;)

ThatsPoorlyDrawn 3 Builds 2 points 31 months ago

He just said mild gaming, and mostly programming, so it seems, he just needed to be able to have 4 monitors, as said in the description...It is still a nice build.

avfguard 1 Build 1 point 31 months ago

I love the military green case, looks slick. I'm curious, why not a cheaper 750 ti? If you're going to spend $150 why not a 270X?

piemancoder 2 points 31 months ago

He said because it had support for quad monitors

Eschaton 6 Builds 1 point 31 months ago

Always nice to see a build that differs from the norm! Also, THANK YOU for actually using your cooling hardware to do some awesome overclocking that actually has a purpose!

All of that being said, there are some small criticisms one could make of this build:

  1. I find it hard to believe you really needed 64gb RAM for your RAMDisk setup. 32gb probably would have been more than enough, given what you're running on it - unless you're trying to load large datasets into RAM?

  2. Not sure you really needed to drop for an 860W PSU; perhaps focusing on a smaller-watt, higher-efficiency design would have served you better?

  3. If you were looking for quad monitor support at the lowest price possible, an AMD card would have been your best bet. I know there are models of the 250X that come in below the $100 mark and support 4+ monitor configurations without the need for splitters: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125512&cm_re=R7_250-_-14-125-512-_-Product

Still, a big +1 for me. Thanks for sharing.

mysticial submitter 5 Builds 1 point 31 months ago

Thanks for the feedback!

1) You're right, I currently don't use all the memory for ram drives. It really is for the massive datasets that I deal with - for which there's no amount of memory is enough. My other rig has >30TB of HDs for the same purpose to give an idea. 64GB is as high as I can reasonably go without going to server hardware (which I've done before). But the cost skyrockets at that point.

2) I tend to lean on the side of safety for PSUs because I've had some bad experiences with one of my dual-socket machines. And if I had known that the CPU would draw almost 300W under load (4.0 GHz), I'd have gone with a 1000W PSU. While it's currently overkill, I wanted to have room for if and when I decide to get better video card(s). I also intend to (eventually) load this thing up with 30+ hard drives.

3) I admit that, I didn't do much research on the video card. :) Though I'd also have to factor in the cost of getting display port -> DVI/HDMI adapters.

Eschaton 6 Builds 1 point 31 months ago

That is a truly crazy amount of draw on that CPU! 140W TDP, right? I struggle to even imagine what those 220W TDP AMD parts must draw in similar situations...

ThatsPoorlyDrawn 3 Builds 1 point 31 months ago

I really like this build...even though it only has a 750ti...Maybe because of that orgasmic processor? Lol. So jealous of this.

(I have that laptop.)

mysticial submitter 5 Builds 1 point 31 months ago

Don't forget: Video cards can be upgraded - which I won't hesitate to do if I ever need it. :)

ThatsPoorlyDrawn 3 Builds 2 points 31 months ago

The 750ti isn't really a joke on gaming, it just isn't a beast.

qsball1999 1 point 31 months ago

That PC would've went nice with Windforce 970 SLI

awlicata 1 Build 1 point 31 months ago

This thing is gorgeous. +100000000

Uhhh...

Nice build BUT...

i7-5960X Extreme Edition and GTX 750 Ti...

Well, nice build, cheers!

johnAtheAwesome 1 point 30 months ago

That is the most adorable GPU in the world!!!

190n 2 Builds 1 point 26 months ago

Cool build. Your parts seem somewhat...disproportionate. I used that GPU in a budget build with an FX-6300. At that budget, I would've gotten at least a 960.

Laith225 1 point 24 months ago

Nice anime posters! :)

MightyAlFred 3 Builds 1 point 23 months ago

I just wander what kind of programming requires a 5960X... I hope I can learn it someday.

mysticial submitter 5 Builds 1 point 22 months ago

It doesn't require it. But it certainly makes compiling a lot faster. I do mostly C++ which is notorious for having long compilation times. In my case, the difference between a 4770K and a 5960X is a minute vs 30 seconds. I should be glad I'm not working on GCC or the Linux kernel since I hear those take hours to compile.

MightyAlFred 3 Builds 1 point 22 months ago

I've also did some work with c and c++ in university, but compile times were never that long. I was just wondering what kind of code actually needed them :) nice job btw! Loving the build.
