I still cannot add voltage to my 6GB 780's. I keep reverting back to 4.2.1, and then X16 comes out with an update. I try it, and it doesn't work. What the heck is going on EVGA? I'm running stock bios, and the max I can get in version 4.2.1 is 1.2v. When I go to set precision x 5.2.5 (or 5 version), it will on stay at stock speeds.. but in the OSD, it shows 1.212 or 1.3?
Any update on the problem with the 780 voltage?
I am going to address this post specifically, as I can get video, if you would like, and debunk this voltage thing right away. Voltage is being applied, and it actually really good at applying what you set.
I just ran through 30 minutes of testing all sorts of voltages, under load and without load, overclocked and not, overvolted and not, until I crashed my computer completely, lol.
So, in Short. GPU-Z shows the absolute closest voltage. HWiNFO64 and Precision were WAY off.
At stock the Multimeter reading was 1.033, GPU-z read 1.025, HWiNFO64 and Precision both read 1.021.
Under load (no extra voltage, just for testing) DMM 1.2v, GPU-Z 1.18v, Precision and HWiNFO64 1.175.
For the next test, I simply overvolted to 1.225 in precision, no Overclock or load at all: DMM. 1.233v, GPU-Z 1.219v... HWiNFO64 and precision 1.021...
Overvolted to 1.225, No Overclock, with a load DMM: 1.25 (the extra .025mv is notorious to the 780Ti cards, and no surprise)!! GPU-Z 1.211 (so close)... Precision and HWiNFO64: 1.175 (nope)...
*last second test: Overvolt to 1.25v with no load: 1.261v GPU-Z: 1.244v (closest I have seen on any software) HWiNFO64 and Prec: 1.025
Overvolt to 1.25v under load: DMM 1.277 GPU-Z: 1.244v and HwINFO64 and Prec: 1.175v.
HWiNFO is not accurate. It chooses, just like Precision, to display whatever it feels like. This is the first time, with the updated GPU-Z, that I have seen ANY software read so close to the actual set voltage. One more test. Going to set Prec to 1.3v and see what DMM and GPU-z say.
DMM: 1.309v and GPU-Z reads out 1.296. That is by far the best software read outs I have seen, so I highly suggest, from this moment on, to utilize GPU-Z and test out your cards that way. Granted, if I were to put the card under load at 1.3v, it would read 1.325v at the DMM and 1.296 on GPU-Z, but that is still incredibly close (30mv difference) to what is reality..
Now, I am uninstalling 5.2.5 and reverting back to 4.2.1 for further test. I am not overclocking, because the claim is that the overvolting isn't working.. which is clearly working just fine while all of the software is wrong. I am pretty sure the overclock itself is tied to Precision, and the overvolting you are experiencing has nothing to do with your frustrations. You may consider your card voltage locked in the bios, but I tested mine on the EVGA voltage locked bios, and as we can see, it works just fine. I did push my cards up to 1.25v and was awarded a BSOD... LOL.. I am guessing that was the voltage lock screaming no, but I have no idea, as usually the drivers crash.
So Preliminary Run:
4.2.1 Stock settings
DMM reads 1.033v
precision 1.024v
HWiNFO64 1.025v
gpu-z: 1.021v
Overvolt to +75mV with no load:
DMM: 1.033v
Pre... just read the lines above, no change at all, on anything.
Overvolt to +75mV and underload.. Exactly the same. No changes at all.
I think your overclock is limited to the software, but the voltage is NOT your problem. Please do note that when the Classified line came out, the overvolting in precision did nothing to help, and then was topped off with the low cap anyway.. If the user didn't have a EVBot, they could do nothing, so they resorted to the ClassyVoltage Tool software, that someone with a 10 pound brain made, and boom, better overvolting was allowed, which allowed for much better overclocking.
I have a feeling that 4.2.1 likes your cards for overclocking, but there may be some other form of magic working against you. I can promise you, after testing this for the last hour now, that the voltage section works just fine.
I would highly suggest moving the symptoms you are having over to the
EVGA PrecisionX 16 5.2.5 bug report thread.. so that maybe they can catch the bug that is happening in your system. There could be many things causing it, and there could even be someone else that helps you get the bug worked out that you are experiencing.
If you would like me to test something else, just let me know. I have almost all of the versions saved on my computer, and I can get the ones I don't have for further testing. If you wish to have video, it will be cell phone video, until I can get the second system back up and running with a capture card. I took a bunch of screen shots, but don't want to spam this thread just for this purpose. The numbers clearly don't lie though, so I am not sure the pictures would help anyway.
