Ok, stupid question incoming. What is this talk of 6-7000 MHz memory clocks? Precision shows my memory clock at 3506 MHz and core clock of 1163MHz....am I supposed to double those numbers or..?
Double the memory not the core.

Generally speaking GDDR5 runs at a clock frequency of around 1000MHz up to around 1750MHz. GDDR5 is what we call "quad pumped" meaning that within one clockcycle it can do 4 data transfers. This creates a lot of confusion because sometimes graphics card specifications list what is called the "datarate" or "effective clockrate" of the memory which is actuall 4x the real clockspeed. To make matters worse, for whatever reason some vendors are listing double the clockrate which is odd because there is nothing on your videocard that runs at that speed.

To clear the confusion somewhat:
  • If the memory speed listed is between 1000MHz and 1750MHz what's listed is the real clockspeed, meaning that the datarate is 4x this value.
  • If the memory speed listed is between 2000MHz and 3500MHz what's listed is meaningless but most likely the datarate is twice this value
  • If the memory speed listed is 4000MHz and over what is listed is not the clockspeed but the datarate.

These figures are valid for GDDR5 only so if the card uses another memory type than GDDR5 you cannot use this list. For the purposes of comparing it's easiest to determine the datarate (also called effective memory clock)

Just a heads up... seems the latest drivers has caused some instability for me... New OC is below...

Hi,

I have the EVGA ACX standard 780, and I noticed in the guide that we can only go to 1212v with soft volt mod and llc disabled. I think I can get to 1300 stable on 1.24v, but that is only with llc disabled. I was wondering what do the soft volt mod and llc disabled do, and if we need both. Sorry if it's covered in the OC guide, I read it and did not see an answer I could understand. Please forgive if already covered, my English is not very good, so apologies again.

Without the voltmod you can go up to 1,212V with a modded bios! if you do the voltmod you can go up to 1,300V!
LLC stands for Load Line Calibration and we use it to make the OC more stable providing fixed voltage with LLC disabled (0%)!
All this if your card has the voltage controller NCP4206 of course!

Thank you very much for your explanation. Since I have a reference PCB GTX 780, it is safe to go up to 1.24V on air?

Well i believe so,yes! But keep an eye on the temperatures! IMO don't let them get over 70C!thumb.gif
Try to lower your ambient temperature if you can, that's the best way ! smile.gif
