System Refresh

[Dayaks]

Just wanted a sanity check. Going to update the rig and gift off what I have to family.

Please let me know if there are better alternatives or something obviously wrong. I am most concerned with errors that will limit overclocking.

All depends on what you're doing with it. If you're a gamer you'd actually get better performance with a 4790K. Do you have a need for 64GB of RAM? Seems a bit overboard unless you have some very specific software need. My current system has 16GB and I don't find them being used even when I have all the horrible RAM hogging development software I tend to run like Visual Studio and Eclipse.

You also don't need such a powerful power supply unless you're planning 4 way SLI and even then it's a bit overkill if you're using 980s.

I'm thinking of SLI Titan X's... do you think my 1200W AX1200 would cut it? I think it might. Maybe I'll take your advice there. The AX1200 only has two years on it.

As per the RAM I know I want at least 32GB for the video encoding I do. Maybe I'll knock that down and get a better SSD... the idea of a RAM disk always tickled me but if I don't have enough SSD space for everything it doesn't quite make sense.

I updated my OP with more info and some changes.

I also flip flop between the 5960x and 5820k.

The main issue with that setup is the mobo: It's not all that reliable.

Now before I go on, I need to know which direction you want to go in:
A) The fastest parts possible at whatever the cost
B) The fastest bang for the buck parts.

To me, it looks like you're heading towards A but kinda wanna switch lanes to B.

That's a heck of an expensive computer. For gaming I think you could pull the CPU back a peg or two without any significant penalty, same with the motherboard and RAM.

Does video encoding really take all that much RAM? Interactive editing, sure, but basic encoding with something like Handbrake is CPU bound. That's where a fast i7 does help.

Samsung 850 pro are fast, reliable SSDs.

I ended up going with a 5820k and using the delta for a Titan X SLI. Seemed like a nice compromise between a 4790k and a 5690x. I had about a 3k budget for mobo+cpu+ram+cards.

Newegg also had a $-90 combo deal on a EVGA P2 1600W and Rampage V Extreme I couldn't pass up. I'll use the 1200W for my cooling system.

Thanks for the comments!

1600W is mental. Put a power meter on your computer at full load, I'd be surprised if it cracked 500W.

Well, with DUAL Titans, maybe slightly more than 500W. But not much.

He probably could have gotten away with a decent 800W PSU and still had headroom.

1600W is enough to basically power his entire system AND an overly elaborate watercooling rig at the same time.

Granted, I'm in no position to talk about extravagance.
I've spent $600 on components to relocate a years-old x58 setup.

 

[Dayaks]

I don't mind the headroom for trisli later, doubt I'll do that though since scaling is marginal most of the time past two cards.

This rig will be cooled below 0C in a month or two to OC the hell out of it. Didn't want to worry about power now or later over $100... Besides larger wattage should equate to larger caps and less voltage variance.

 

[chenw]

0C? are you also using a refrigeration system or are you using phase change coolants?

 

[Dayaks]

Going to try throwing the system in a sealed chamber with desiccant. Going to use a lot of TECs and dump the heat into either my house or pool depending on the season. Not a huge fan of compressors.... Wife doesn't exactly know the scale of this project.

I have a thread I need to update in the extreme cooling section. I am expediting the project.

But anywho it looks like the Titan X is hitting it's 300W TDP pretty quickly from the benchmarks I've seen. I imagine the system will be pulling around 700-900 watts OC'd. I was also leary of doing such an expensive build (this is my most expensive by 2x's) with a 2-3 year old PSU and being close to above 80% usage. [H] has a review where a 7 year old one was out of spec on it's rails.

 

[chenw]

I wonder how much you could OC titan X if you put it under LHe...

 

[Dayaks]

I wonder how much you could OC titan X if you put it under LHe...

lol. Well, I would imagine above 2100 Mhz. If a 980 can do 2200 Mhz on LN2.

I get my Titan Xs today. I'm interested to see how high they boost without the TDP cap in place. One of the review sites mentioned they hit 1450 briefly but TDP kicked in. If that's normal that's not far off from a 980 and the bigger die size isn't hurting it too much.

I'm more interested in if it scales linearly. I.E. if 80C is 1450 and -190C is 2100 (or whatever it may be), would 10C be 1606 Mhz? I am sure there's more of gain early and then diminishing returns later, which is better for me. I expect my 24/7 fluid temp to be around -10C year around with 800 watts load. If I don't kill the entire system somehow first.
