Highly likely.

Cheers.

personally I think using a p4 with that nice video card is just a waste of time...get a 4 core processor amd intel, that is a waste of time and money using a p4 :(

"...get a 4 core processor amd intel"

what does that mean? A new hybrid maybe?

I'm sorry you don't approve of my choices :(
I will check in with you next time I make a life decision.

Have you had anymore luck getting the GPU usage up? Your 780 should be up around 90% with 2 or 3 MBs. If it's throttling from heat, one way to tell would be to leave the side panel off and place a 12 inch box fan about a foot away. That should cure any heat problems if present. It's an easy check.

With MB units it is all GPU so they will crunch fine. It is the AP WU that will suffer, big time, as the GPU need a considerable amount of CPU help with them.

---

Yea the GPU usage went up after I turned off the built-in Intel GPU and turned up the CPU fan speed. Suddenly everything sped up, 780 GPU and the 5 CPU are kicking butt now!

---

With 780ti the sweet spot seems to be 2 WU's per GPU. As long as I leave my fans on full speed, I can crunch on 7(virtual) cores and leave 1 core free to help the GPU. If I don't want to have my fans (10 x 140mm) up all the way, I only keep 5 cores crunching, which keeps the temperature down. And yes haswell is definitely hot. I have mine OC'd to 4500MHz and even with my water cooling and 240mm radiator and gigantic case, the CPU temperature is 70 Celsius. If I didn't have all these resources dedicating to cooling the CPU it would be like 95 Celsius.
If you are running 3 or more WU's, load up GPU-Z and drop the number of WU down to 2 and see if you are running near 100% GPU load with the one less WU. Basically you want to have the lower number of WU's running that gets near 100% GPU load otherwise the extra WU's arent doing any benefit.

I just broke 28,000 RAC, which is my highest ever, with the help of the 780. Looking a lot better now.

I'm starting to see that I need to add water cooling to my box. Right now it is winter time here and the house is cool. I don't want to kill any components with heat.

Is there water cooling for the GPU also (say the 780)? Or is cooling just for the processor?

Yes, there are water cooling kits for gpu, lots of them, they been around for years.

Check the card manufacturer website, they might have a kit for your card ready to go.

Awesome. Thank you sir.

All GPU water cooling is do-it-your-self. Water in my PC is scary enough without me building it.

Here are some cards that come ready for water cooling from the factory:

Probably recommended to water cool the GPU and the CPU I assume?

Not really. "Pilot's choice" so to speak. I have not done one, but the simple setup would be:
* one tube for cooler liquid coming in
* one tube for warm water coming out
* radiator on the outside of the case (probably with fan)
* reservoir on the outside of the case
* pump on the outside of the case
* miscellaneous stuff (coolant additive, maybe filter, maybe flow indicator, etc., etc., etc.)

I don't know if this is good site or not, but it seems to have the kits and individual parts. So look at the kits so you know what parts make the kit, then you can either start looking at the kits or start planning your own kit from individual parts.

It is not a closed loop setup like one can buy ready made from the factory. One still had to build a radiator, pump and tubing. There is a kit for water cooling 4 GTX690's 8 GPUs. So I thought about it but I'm holding off until SETI starts giving more credit.

There is much to be said about having good case cooling compared to water cooling. I recently replaced my front and rear case fans from the standard 50cfm and 40cfm to high flow ones with rates of 80cfm and 95cfm respectively. This has reduced the internal temps by around 10c and reduced the 7 internal fan speeds by around 14% (they dont have to spin as hard as internal temps aren't as high).

I have an nVidia 580 and a nVidia 570 in the case, plus an overclocked intel i7 2600K with appropriate oversized air cooler on it. (that in itself can pump 90cfm of hot air inside the case)- so between all three working hard there is substantial heat build up.

Overall cost for the new fans was a 'massive' $35 AUD. So you don't necessarily have to go full water cooling to keep your system both performing well and reliably.

Just my 2c worth.

Case? The best case is no case. I have a 120V AC fan blowing the "artic vortex" directly on the GPUs.

You are correct about air flow for those who insist on a case. When power supplies has their intake inside the case many could not get enough air with all the other fans blowing out.

---

I have the same situation - no case. It takes several fans surrounding the MB and GPUs and a large AC window fan bringing in the outside air sitting on the window sill. Heat duct in this room is closed and blocked off and so is the door. The window faces north which is quite nice when a cold front comes through. Below zero temps outside are a blessing for this machine!

I may have to look at water cooling, at least for the summer if I want to run a configuration for maximum RAC all year. It's winter here so it's easy to ignore the problem for now since there is no problem. There is no way this hardware configuration could ever be put in a case and live - I wouldn't even attempt it.

I like running this machine flat out in winter since we get very good electric rates in the winter - 3.8 cents per kwh!
