post #6731 of 10768
I would like to understand something :

here is my score 3DMark with Sea Hawk X :

mini_17042101265217369814993090.png

As you can see, frequency core is 1617MHz.
In MSI AB, I put voltage slider to 100% and power limit to 120%

Result => I only get 2000MHz maximum as boost frequency in time spy...

Now, when I look this result for example :

http://cdn.overclock.net/9/92/92e2e136_timespyahowe.png

The Core frequency is lower than mine (1554MHz) and the boost frequency is 2075MHz !

In Time Spy, why can't I go over 2000MHz-2012MHz with a start frequency at 1617MHz with power limit at 120% and slider voltage at 100% in MSI AB, while a lot of you can reach 2050MHz average in the same conditions....?

Is my card unable to go to its power limit ??

Power limited.

I don't think we'll find one. The best would have been the Aorus which is 375 watts and that doesn't work at all.

Has nothing to do with either, it's just the card being a 6+8 pin.

Ah ok, this power limitation is due to 6+8 pin ? I ddin't know it was the main reason. Ithought it was Silicon lottery, as you told me yesterday by PM smile.gif
It means, i have more chance to have more headroom for overclock with a FE card 8+8pins (Even if it will be hotter) ?

Honestly, if you're thinking of modding your FE to have 2x 8-pins, sell your 1080 Ti FE and buy an aftermarket card that already has that configuration. You're going down a path that will destroy your warranty for sure since you can't undo that.

Well silicon lottery can somewhat play.

Some cards can get higher clocks with higher voltages but higher voltages require higher power.

Let's say 1.000v for 300 watt, well if you overvolt to 1.092v than it needs around 330 watts.

There is no FE cards with 8+8. They only come with 8+6.

I'm not sure if you're understanding the silicon lottery. If you can't run your card at a certain clock and voltage doing light task then power will do nothing for you.

If you set 2100 Mhz at 1.093v and you can't run heaven benchmark even for a second then power will do nothing for you.

If you can make it through a run of heaven and boost 3.0 is adjusting clocks to meet power availability, and you do run through a few scenes at 2100 Mhz, then power might help you.

I uploaded the Zotac Amp Extreme bios to TechPowerUp, which has a power limit of 384 W. It does not play nicely with the FE and probably won't do you much good with other cards either. It has some fancy weird stuff going on that other cards don't (16+2 power phases, 2x power boost chips, some sort of proprietary voltage regulation).

Ok, thanks.

2000MHz maximum stable frequency at 1.093V in Time Spy...That's really a card which is far far below average overclock capabilities, especially on water... mad.gif
