Feel dense asking this, but got my new 1080ti recently, slapped under an AIO now and am dabbling with overclocking, (and undervolting/ voltage curve overcloking using afterburner)

I understand the core clock and all those Mhz speeds and the boost principle, but I don't understand the memory clock Mhz speeds. Everywhere I look people are saying my memory is at 6000Mhz+ or whatever - my memory clock is running at 1376Mhz. What gives? Do you multiply the number reported in GPUz/ hardware info or whatever by x4 or x5 or something?
 
Cheers fellas, that clears that up!

Is it reeeeaaaaly worth overlcloking the memory on the 1080ti? Reason I ask is I've now got it with a kraken g10, corsair h55 AIO set up. Working really well, temps are great but am a bit worried about VRM temps as I've not bothered with adding heatsinks this time to the memory chips etc etc (I did with a previous card in the past, and that didn't end well when I removed them!)

Overclocking the memory will put added stress on the vrm chips, memory chips and temps no??
 
I've found it varies strangely. Some cards really open up with an overclock on the memory. Others not so much.

Yes there is added stress. The chances of actually damaging anything is vanishingly low in my experience/reading around.

The 1080Ti is hugely powerful, what resolution and settings do you play at? It's your card at the end of the day, don't feel you have to overclock it because others do.
 
Quad Pumped but some of your Apps read it as Double so 6GHZ (6000mhz) on a older Titan X (easier number to work with) would be seen as 3000mhz in some Apps but in others 1500mhz.
 
Isn't it x8 for the 1080Ti's GDDR5X? For mine the box/product page says 11GHz effective, but all monitors just say the base speed which is 1376/1377MHz odd.

As mentioned previously, overclocking the memory doesn't seem to do anything with the 1080Ti, I found tweaking the power limits and core speed to be better.
