Memory clock OC - high offset dangerous?

skaughtz

I have a 2070 I use for mining Ethereum (but this question should apply to any card).  I have the voltage locked in at 700mV, with the core clock at stock, and the memory clock at +500MHz.  The card runs at 47C and only pulls 92W.  All good.

 

Yesterday I tinkered with the memory clock and managed to get it up to +1350MHz stable, before I decided to look more into what I was doing.  The card temperature remained at 47C, but the power draw increased to 99W.  The hash rate increased 5Mh/s, but I was concerned that I was destroying the memory, either through heat or stress (there is no monitor for the memory temp) so I took it back down to +500MHz.

 

+1350MHz seems like a crazy amount to just be luck of the silicon.  Is it dangerous to run an overclock like that, or should I be grateful that the card can do it (and potentially more) and rock it out?

 

Appreciate any advice.

I would check your memory temps, something like HWINFO should show memory temps instead of the GPU temps.  Your GPU is probably at 47C, your memory is definitely not...  (assuming your 2070 can show memory temps, i can't check without knowing the model you have)

Thanks, man.  Any suggestion on what memory temperatures are safe to run constantly?

I am honestly not sure on the 2070...  someone else could probably comment..  i know memory is usually higher then a cpu\gpu..  Like the 3080 can be around 100C in memory with the GDDR6X....

Mid 80s would be ideal for memory. Tbh more work = more power draw, not surprising.

I also have an EVGA 2060 KO Ultra Gaming card that is shorter than my 2070 (EVGA Black Gaming) but has sensors for memory temp.  That card runs warmer just because of its smaller size and cooler.  I realize that it is not apples to apples, but if the 2060 hits a certain memory clock overclock with its memory running at a safe temperature (say, +1000MHz at 74C), would it be safe to assume that the 2070 is not running any higher than that at the same speeds?  The 2070 runs cool but does not have sensors for the memory temperature.  At +500MHz on the 2060, the memory is reading 72C with 85W total draw, while at +1000MHz it rose to 74C and 91W total draw.
