So your running your gpu on the non stock psu? Might wanna re read my post. I said you need a better psu to get the full benefit of the gpu, which your not using the x51 psu, correct?

I TESTED IT ON MY 1KW PSU AND GOT THE SAME NUMBERS AS MY STOCK PSU. My whole first post is about running on the stock psu. Hi welcome to the party. The pisture is there to shave i have tested it on a psu so people know im not just saying random stuff like most people on here with the OMG you cant run that because its better then mine so it takes to much power.
Ok back on topic. max i was able to get was the full 132% tdp "My 680 is running a modded bios keep in mind" and clocks a little over 1,300 on the gpu and 7ghz on the mem. Its stable. temps are fine "Gpu as well as case temp sensors." 3 hours of 3dMark looping. Can it run it? Yes. Sould you run it" No. Its hitting the PSU pretty hard and at those clocks i would not be surprised to see caps leaking after prolonged use. 1111 on the core seems to be the useable max for the core in terms of power the stock psu can put out and abuse the components can take. I have not had any issues and its been running like a champ with heavy wow use "A ton of 25m raiding at 2k res.".
My recamendation for anyone wanting to run a GTX 680 off the stock psu are as fallowed.
-Ditch the stock HDD. Swap it for a SSD
-Mod your PCIe power plug. It will not fit in a GTX 680 unless you do so. Or just take a old psu and make a new harness that plugs into the stock port "Dell flip flopped the 4 pin plug."
-Rear exhaust coolers only.
-Limit the amount of USB devices in use. Im using a Logitech G19 keyboard and Razer Naga epic as my only USB devices.
-If you can. Get a card with a high ASIC quality rating. Mine is 95%. Do not expect to hit the clocks i have if yours is say 70%. Your card will require a little mower power then mine. "Tip, Usually versions like the EVGA classafied and Zotac AMPED will have binned gpu's that have the higher ASIC quality rating. However Pretty much every high end Asus card i had or seen used typical binnings. So i would avoid them for this application.
-Start off at the stock ref. clocks. If you need more power only go as high as 110% TDP with 1111mhz on the core. "Pushing someone tends to move them faster then just giving them a round house kick below the belt. Just because your gpu can clock to over 1300mhz does not mean you have to clock it that high. Also factor in boost into your clocks so you dont overshoot your overclock you want for those who are not forcing p-states.
-Set your psu on something hard. Not under a blanket or on the carpet. It gets hot but no hotter then it does when powering the stock set up. "Infared temp tested". Theory behind this is your hitting the psu pretty hard so trying to help cool it a little is just that much better.
-If you have stability issues. Plug it directly into your outlet and not a power strip. Sometimes if you have a cheap power strip they can give you stability issues when your taxing a psu this much.
-Also if you overclock to much and you get a shut down dont worry. You just tripped the psu's bult in guard. just down clock a little then try again. But you will need to unplug the psu from the wall in order to reset it.
As for the cpu cooling project. i ordered my Alu. today "Alu. is better then copper at disappointing heat." Going to go all Alu. on this build that way i wont have to worry about the whole issues that come with mixing alu and copper and im taking as much heat away from the cpu as i can. On sunday i will be trying to see about making a Alu. res and machining some small heatsinks in the res to help out even more. But i have changed my radiator des. up a bit. Sould work great to cool a i7 4770k overclocked if someone was to slap another mitx mobo in and use a k series cpu. But im shooting for a system that will cool the 4770 st 3.9 and a gpu like a gtx 660, 76. Nothng major like a 670,680,770. Load temps on the cpu with the gpu in the loop of 65c along with the gpu at say 65c would be great. Single loop for say a i7 im hoping for load temps in the 45's. Nothing earth shattering just a full super compact loop that does not preform worse then the stock heatsink like some that i seen.
And also on a side note. Im unable to disable HT in the bios. I disable it and it works. I try to cold boot it the system fails to post and restore the defaults. I prefer no HT as in gaming it makes no diff and just sucks up more power and makes more heat but im unable to disable this. I really dont care but if someone gets the idea to do this to save some power i would not even waste my time because the stock bios sucks and seems to be buggy. But i'll unlock the current X51 R2's bios and upload it when i finish my WC set up in it and get some free time. So if anyone would want to beta test it when i start just post up and i'll pm you the link when i get it all unlocked.
