OTOY Forums

Awesome, enjoy!


@Tom: It is a nice OC, I flashed the cards to unlock the voltage and get a better base clock.
For air coolers, they cool incredibly well, but of course the will get loud on an aggressive profile, so I would like to water cool just to control the noise and keep this overclock 24/7. The problem is finding the time to research and source the parts - I'd need to go for a new case to cope with two loops. For now, they'll stay on air.

Overall very happy with it, I also use them for TurbulenceFD, and I tried to fill the RAM with a sim but it got to the end of the timeline before it filled - that's awesome

I'd keep an eye out for the 980Ti's if they OC as well as these TitanX, it'll be an awesome farm card!

Here's a grab from the monitoring on a recent render:



This rendered just under twice as fast as my previous 780ti/780ti/Titan rig.

damn... i though that since the titan is smaller and when placed over the 780 there is some free space over the fans, it would be better. I was afraid of covering the titan fan completely since there is not much space for the air to circulate in between the two cards.
What do you think?

Nice!

think You don't need to go with new case or something like that - simply get external rad & pump/res - that's the best idea & way more safe...

Drop Your mail to my as dm/pm - I'll send You some ideas =)

how you flashed the Titan X? Is it a firmware?
With Afterburner what is the right overclock confing ?

regards

I'd like to build a new rig with 4 Titan X liquid cooled.
Any suggestion? Do I need a dual Xeon mb to handle 4 PCI-E 16X busses?
I saw the Maingear rigs and they are impressive...
Does the liquid need to be refilled? My air cooled workstations work 24/7.

Yep! I flashed them all to a BIOS that takes the TDP limit to 425W (I don't go that high on air though)
I use EVGA Precision for the OC management but Afterburner/NVinspector would do fine, they all give access to the same features.

That'd be a great rig, you don't need a Xeon mobo but decent X99 would be recommended (4 x PCIE 3.0 slots should be plenty!)
If you're getting Maingear to build it, I'm sure they'd advise on the liquid and required maintenance, most loops have some kind of biocide (chemical/silver coil) to keep the water clean, so it wouldn't need a full drain too often, even then it's not a particularly difficult procedure.

If you went X99 8-core & 4-way TitanX, you'd be looking at a minimum safe PSU of 1500W (or smaller ones for System and GPU separate), my rig barely goes over 850W with 3-way at full 100% load, but it's always good to have some headroom!

there are a lot of different routes to take, but if You want to have flexible system..
that in case of GPU failure You could keep it running in no time..
there's a lot of things to think about, like:

* "PCIe switches" (to disable any card You choose) - useful for fast trouble shooting without any need to physically take those cards out of PCIe slots..
* You can plumb a loop inside Your case _ looks good, but it's more risky, parts need to be way more compatible etc. - external loop is way easier to maintain & even upgrade.
* things like quick disconnects, drainage systems & other well though out features to help quick disassembly & or modification of loop..
- etc. as every situation is slightly different there might be other things to thought out..if You don't want to have long downtime 'cased by maintenance..

no, You don't need those as single 40 lane CPU + PLX chip on motherboard should provide You 4x 16lanes without any need for second CPU. Additional CPU power might help to process Your scene & send it out to GPU faster, but..if You're not taxing Your CPUs with some extensive rendering workloads relying on them.. then going single OCed high-end CPU deal offers better value. Plus if You get a loop for GPUs include CPU to get conservative yet stable OC on it too..

Liquid needs to be refilled as it evaporates, slowly but..You should check Your system from leaks once in a while..& it good to have some plan if..(something would happen - few extra fittings, tube, quick disconnects, etc..but overall some do run for years without any problems). Even best systems can go out..no matter if aircooled or watercooled..but if You don't plan ahead, You can make Yourself a 'favour'..

Maingear rig with 4x TitanZ is sick to say the least - though personally, I'd choose anything less flashy (less disco/xmas tree decoration), but more flexible, easier to maintain - heavy duty machine & as simple as possible loop. (drop me a DM & I'll send You some shots & ideas don't want to spam this thread =)

You can put one of them in the 4X slot for better cooling. I did a bunch of tests and there is no performance degradation in the slightest moving the one card from the 16x to the 4x.

Just a nugget of info.

Thanks so much for the tip!
So, which one on the 4x slot? the 780?

Looks like the gtx 780 has to go to the 16x because mac wont get to the boot screen if on the 4x. No clue why but...
