LLC will drop your load voltage right? especially if you are stressing the card so you will never see a reading of 1.210 under load unless you disabled LLC...

Sorry so used to some acronyms forget to explain sometimes. LLC = Load Line Calibration...basically a mechanism to protect the core. It drops voltage when the card is under full load so that any spikes during transitions from lower to highest activity is not going to overshoot the set voltage.

If you set 1.210v, LLC will always make sure that the load voltage is lower than this, allowing for temporary spikes to come up to the 1.210 level....so if you measure voltage you will see less than you set on average.

If you disable LLC you would get 1.210 through the GPU core with the disadvantage that spikes could rise above this level.

It's like the overflow on your bath...it's below the max level of the bath so when you fill the bath and then get in it, you getting in doesn't overflow onto the floor...the bath has made sure that no matter what, water won't go over the side...

Hi Arne, thanks for explaining. Been looking for the LLC option in my gpu tweak 2 and I cant seem to find it. I don't remember the normal gpu tweak has that option too. Also I've not seen the nax voltage used in the monitor tab to hit 1.210v, only 1185 with 1173 most of the time under load, which is weird.

I thought my card was underperforming because 1132 core clock (1210 during gaming) boost and 7050 on the memory is pretty disappointing with the voltage maxed in gpu tweak. Is that OC range on air normal for my card?

Would you also be so kind to tell me where and how can i disable the LLC for my matrix platinum? Am currently using the lastest asus gpu tweak 2.

I can't help with GPUTweak I'm afraid...I have never liked it and only ever used it a couple of times...

If the option to disable LLC was there it would show up but I guess it's not? or you have to switch to LN2 bios if those cards have that?

I have always preferred Precision X or Afterburner....you could investigate one of those....clean uninstall GPU Tweak first...unless there is some specific reason you need GPU tweak for that card?

Decent guide here for comparison...http://www.hardocp.com/article/2014/09/22/asus_rog_gtx_780_ti_matrix_platinum_video_card_review/3#.V...

Makes your results seem about what they should be

🙂

Hi Arne, you mean I cannot adjust the voltage for my matrix platinum unless I switch to LN2 mode? I don't plan to go on that mode as I am running it on air.

Weird, a card that costs so much but is voltage locked. I have tried Precision X and Afterburner, both of them don't have the option to disable LLC if I remembered correctly.

The link you showed me does not post the screenshot of the voltage of the card in GPU Monitor which is hard to compare lol.

Yes, I'm pretty sure those cards are locked (as Nvidia wants) to a maximum 1.21v

LN2 BIOS needs some hardware tweaks as far as I remember...like removing resistors so not for the average OCer.

Seems stock BIOS locks LLC ...

Very few cards allow you real access to voltage these days....always have to void your warranty with BIOS or hardware tweaks....only occasional odd versions like kingpin editions let you play...
