For me this is beautifull, i can keep 1215mhz now on the gpu stable ( i do not need higher) @ 1.225 volt stable, otherwise i needed to set it higher to compensate the droop.

Kudos and rep for you!
I just use this in the safe way and not on highest volt, now with this stable volts/vdroop i am a happy camper thumb.gif

Edit:

@ op:

Is it possible to read the temps of the vrm's?
I see that in the sheet also i think ( but hey i am a complete noob so dont attack me tongue.gif )

Maybe but that's going to be a bit far off.

Before you input the command,you use /sg (select gpu) to select which GPU you are applying it to

so for instance youd open the command window and type msiafterburner /sg0 /wi3,20,de,00 for GPU1 and for your second card youd input msiafterburner /sg1 /wi3,20,de,00 and I assume if you had a 3rd/fourth GPU you'd use /sg2 and /sg3

Nice one, adding to the OP

With this you will get no vdroop at all.

I would guess if you do the /r check for the VRM that would tell you. Did you see the response I posted about precision x osd?

Totally depends on if the classy uses the same controller for the VRM power delivery (NCP4206) If it does I don't see why not.

Pretty much this. Try talking to the chip, if you get a response you're in there.

Well with all this VRM roasting 1.3v LLC disabled goodness going on. I fealt scared with my custom cooling setup (universal gpu block and large copper heatsinks on VRM cooled with fan) to push tooo hard with voltage especially for daily gaming and I did not hear back from people on their water cooled VRM temps. So I dug around a little (fingers crawling across google) and I found this.

These are VRM temps of varios titan full cover waterblocks at load:
Warning: Spoiler! (Click to show)

It comes from this site: http://www.xtremerigs.net/reviews/water-cooling/nvidia-titan-water-block-roundup-coming-soon/

That link in addition to the graph I shared here has VRM idle temps, as well as gpu temps.
GPU temps are what we all usually look at first, but with the sickly vrm's on this card and the GREAT work done to reclaim at least SOME of what Nvidia whitheld I think VRM temps are #1 and OHHHH MY not all waterblocks are created equal. Well they mostly are other than 1 by a LARGE margin!!!

This should be a main concern by those of us wanting to push these volts and comparing the HC block to the EK block WOW WHAT A DIFFERENCE!

Good info, that's scary if that's on water. I'm guessing on air that they could be getting quite toasty.

any ideas ?

Yeah and those are I believe at stock.

With 1.23v and 1202 with my modded cooling I am getting about 80 - 85c ( would be hotter I am sure on a hot day or with hours of gaming. at 1.19v and 1137 I am about 5c lower than that ... again that is with large copper sinks on vrm (vram sinks from enzotech the big ones) and strong fans on them. I did not test "stock settings" but the HC block does not look like much of an improvement to me over what I have (better yes but not night and day) the EK on the other hand I am struggling not to just make in IMPULSE purchase of then right now.

If anyone wants to part with their ek blocks and change to a HC or something for looks, please pm me hehe.

Well I think that we'll know soon enough if VRMs stop popping.

thats crazy that the EK blocks perform so much better than the rest... really making me rethink the swiftech Komodo blocks
