But it seems to score better than previously recorded at 1254..

Weird..

eh then that means you are giving it either the max it can get or thats as high as the voltage table readings can go in the bios

Many cards should be locked by hardware to not allow over 1,212V

and for evilkitty:

if you want to mess around then try this:
1215_test_only_650ti.zip 57k .zip file
Not too much changed but still always some risk...
boost table only until 1215, so if it does work, then need to go higher with software if stable...
but for testing better not to touch power sliders with this or raise max to sky high, if you feel it might do more, downclock memory to 2500 via software first and try if it gets better results

am not sure about 650 and how it works (power distribution etc)...
maybe need to change voltage back to 1,212-1,212 etc if it is not getting to 1,212V
but it is for testing only and probably needs better adjustment on individual voltage sliders if it works

But as far as i know you are already getting normal overclock for 650ti

i just dont understand why you get different oc on win and linux

I can't even break 1280 before.. Gotta go test the card..

+1 rep

Thank you!!!

So are you saying that setting the voltage to 1.1875 (which boosts to 1.212V anyway) gives you better overclock than setting it directly to 1.212V in BIOS?

Nope.. Never said a thing about setting the voltage to 1.1875.. wink.gif

It's on 1.212 which gives out a max of 70C in heavy gaming..

I have adjusted every slider to give it 1.225 Volts but CPU-Z said it was being capped due to voltage limit. The Bios defined the 1302 GPU and 1752 VRAM. But during testing, the clock stays at 1254MHz. I have it clocked to 1267MHz before and recorded some tests as well.

It is weird that the stated 1254 MHz (The Bios defined the 1302 GPU and 1752 VRAM) pushes out better scores than the Bios defined 1254 and 1267.

I guess the PCIE power stabilized the card that even hitting 7000MHz on the RAM, the artifacts were inexistent.

Also tested setting the voltages to 1.212 max on each slider and 1302 MHz GPU which crashed immediately. doh.gif

i revealed that lol. linux does not allow the same software control that windows allows. in windows you can give more software by telling the card to take more power without having to oc. linux just has the bare minimum drivers that allow you to have all the functions of a gpu but it lets the gpu run off bios alone and the gpu must request any changes so with the bios requests you will only get what is set default in the bios as there is no way to really push more power in a stable way. nvclock suxx or for me it does as it wont work right and usually crashes when i attempt to use it.

i dont even remember what my main reason was to not use 1,212V was... but probably there was something rolleyes.gif
since it works on 1,187V setting very well then left it there...
if you are setting higher clocks and losing performance then you are overheating or not getting enough power... at 70C it starts to throttle slightly...
basically all i cared was to set boost limit and boost table afterwards to max out right at my card limit, tdp and normal boost clock was left basically untouched
if you are lucky then you might be able to save some voltages on higher speeds... lower temp + less power = more time at higher clocks....

Sometimes setting lower voltage results in higher overall score even when max clock reduces wink.gif
that was the thing why i was testing voltages/speed until i figured out my pci-e thing, to not let it use too high voltage when not needed etc...
But it is effective only when power or temp limits you. Since i now provide enough juice and keep cool to not throttle, it was basically pointess.

First time saw cooler on my windforce 3X i was like: "does it really need it?", but since i can push it without voltmod to almost 70C with open PC in cool room, auto fan, i can understand biggrin.gif
If i had closed box then i'd be running 760/770 bios to stop thermal throttling at 70C probably.

have not tried to test what happens under linux, but it must select speeds etc from bios, so there should be a way to get it working, when it does not take speeds from the top speeds, then drive boost table higher and it should select from same slot what now has higher speed etc... at same time it might then use lower voltages too and must manually adjust sliders for them to specific value

since i'm not familiar with it then ofc i do not know... but anything usable by windows should be done on linux too, but then the same card might not work under windows (when there's need to drive boost table too high). Basically i have all my settings in bios too and i do not use any software to oc my card, only bios and nvidia own drivers.
But i'll stay far from linux biggrin.gif (except Knoppix live what is sometimes needed)

whatever works on windows would make sense for it to work in linux but unfortunnately thats not the way it works. microsoft is based off unix in another form but as there are differences between linux distros that same barrier lies between windows and linux. it will use the card but of course if you look at your cards bios it will have requirements for each clock and the problem is that even when you set the voltages at a fixed rate you are going above the configured safety max voltages.i am not sure but i think on a driver level these voltage states are defined and nobody is tweaking anything to oc as in linux we are more worried about getting sli to work on linux or getting amd drivers to work better stuff like that so in the end your card will follow the voltage bump to an extent but not the same as in windows where people dont have to build on to their os to give it everything it needs. You have to be able to define higher power states and voltage states on a software level to complement the firmware level. this is why windows is so big datawise compared to linux. you are given the base os in linux and you have to add whatever you need yourself. this is also why linux is more secure than windows.

Gotcha. So raising the pcie power "can possibly" remove the artifacts that were once present in a high overclock, yes? In that case can I just modify all DEF power values of the BIOS to be equal to their stock MAX values without doing any potential damage to the card?

Pretty safe I should say. I have modified mine with a 660TI Bios as reference. And even went higher on all the Parameters.
Same Temps, Artifacts gone at 1750 MHz on the VRAM.
