4070 inno 3d X2 voltage

[billyboyRAB]

I have the above card and was looking to undervolt it, however everygiide has them being able to push the power limit to 110% whereas this card only allows 100% despite checking the appropriate settings.

Im guessing this card is hardlocked in the bios??

If it is would lowering the power limit have the same effect in lowering the MV whole retaining almost full performance??

TIA

Edit: I misread, does your slider not move from 100%? I don't know your model but only two of the MSRP 8pin cards allow PL over 100%, asus dual and GB windforce


Its normal on the 4070, I have the winforce with +8% PL. It won't draw over 200w unless you put a big RT load on it, try port royal, i can draw 208w on that but nothing else will pull over 200, best thing to do is a UV over the stock max of 2790mhz.

A nice conservative one you can most likely do is 1v @ 2850mhz, you wont hit any performance cap limiters, and get a good reduction in temp (66c to 58c for me) and big power reduction plus better than stock performance, add 1000 to memory too easily do that, these cards UV very well.

Look into though, theres two ways to UV on the curve, the most popular method will cause clock stretching though, the best method is undervolting every point on the curve. Ill do some pics later if you need

Thnx for the reply.

Yeah pics would be great if u can. I'm new to this having not used a pc for a good 5 years or so.

Just edited my post, does your slider not move from 100%, is the card 8pin, if so don't worry its locked. But you can still get some nice UV, ill post examples tonight and the difference between two methods of UV the curve, handy to know,

Looks like nearly all 4070 cards are locked at 100%. Only the OC cards (>2475mhz boost) with higher clocks have higher limits available.

Ada cards aren't really power limited anyway.

 

[MegaPinches]

Stock boost is around 2790 on all 8 pin cards and the limit is power even at stock you are hitting PL continuously, only overclocking you will see the odd voltage/thermal limit while constantly in PL

The 2475 is just Nvidia gareenteed boost

So normal method used is this to produce Pic 1:

Used this for years but found out recently that its not ideal and there is a better way to get less clock stretching and better performance.

So rather than doing this, what you want to do is (pic 2) ***EDIT FOUND THE VIDEO, credit to this guy and his guide, couldn't find earlier:

1. open up Afterburner and open curve editor
2.Find the voltage you wish to use, I will use 1000Mv, Hold left mouse button and to the left (on curve editor) you will see the clock speed at that voltage, for me its 2655mhz
3.I want 2850mhz @ 1000Mv so add the difference into Core Clock box on main Afterburner GUI, so add +195 and hit enter.
4.Now Hold Shift and select anywhere on the curve editor in between 1000 and 1010Mv but not on the node and drag the big box to the far right.
5.Release Shift then select any node in the highlighted box after 1000mv and pull down past 2850mhz and press enter and it will flatten the curve after 2850mhz

I know this isn't new to some but a lot of people using the old method but this way is better.

Some examples you might wanna try to find your baseline

0.0975 2790 +1000
0.0985 2805 +1000
1.000 2850 +1000
1.025 2895 +1000 +104%
1.035 2925 +1000 +108%

Thing to bare in mind, clocks speeds only go up in 15mhz increments, always use at least 2 bins down from where you crash, if not 3.

E.g 1v at 2880mhz will crash for me, you cant use 2865mhz at 1v because on light loads the clock will still boost to 2880mhz occasionally and will be unstable. I recommend using Timespy loop or port royal loop to find your clocks and go from there

Also GDDR6X is error correcting so you can use max OC on memory +2000 and it won't crash but will result in worse performance, so finding your memory max is harder and application dependent, +1000 is pretty tried and tested so just add +1000 to memory as well.

1.000 2850 +1000 for me is sweet spot, once you start going 1.025mV + your gonna bump into PL and not save on power if that is your aim. Still lower temps than stock though

Thnx for this. I'm going to give this a go when I come home from work tonight.
