What to do with GPU Memory Clock

I'm using that guide to overclock my GPU.  It says to increase the core clock in increments of 20MHz and then run a benchmark, but it doesn't say what to do with the memory clock.  Do I just leave that alone?

 

Also, should the core voltage always be at 100%?

Core voltage slider doesn't do much on an Nvidia GPU so it doesn't matter I think, but you should increase the power limit to the max when overclocking to get the most out of it.

Do the same with the Memory Clock, but find a stable frequency for the Core Clock first

Push voltage up to the max, push power limit and thermal limit to the max, then give her the beans till she is unstable. 

For memory, it is going to overclock more than the core. What I recommend is try to find other cards and see what reviewers overclocked their cards to. Then use that as a baseline for your card. Though personally I am a bit more haphazard with overlcocking my video card memory. Increase by 100MHz and see if it fails, if not do it again by 100. You will be surprised at how much you can push the ram. Then if it gets unstable, back down 100 and increase by 20 from there. 

That is how I do it so <.<

 

Also as the guy above said. Core clock comes first before memory.

it applies a bias to the VF curve but yeah there's not much adjustment in it

 

what GPU are you using? this determines what the process is for memory overclocking. HBM behaves differently to GDDR5 which behaves differently to GDDR6

 

for HBM you can usually get away with a little bump but, takinng my V64 into example, it comes at 945MHz and mine maxes out in compute applications at 1030MHz before it becomes unstable, so, +100mhz or thereabouts is all you really get

 

for GDDR6, you can generally hit +1000 on the memory clock and it will take it and run fine. this is the case with my 2080Ti

 

for GDDR5/X there is a wall you run into at a certain point where the memory chips change over from tight timings to loose timings to accomodate your desired memory frequency and from that point on it's kind of a losing battle. the advice there is to open something like unigine valley and use space to pause the stress test in a place where the FPS is relatively stable. Then, start by applying +250 to your memory and work up in 50mhz steps from there until you see the FPS actually drop because of the switch to looser timings.

go back one 50MHz step to where it was giving the highest fps and leave it for, say, an hour, to make sure the memory is truly stable

You know, that is smart and I am going to use that going forward.

Thanks for all the tips, guys!

 

Do these settings look appropriate?  After a lot of tweaking and testing, this configuration seems stable.  I used the 3DMark benchmarks for Time Spy and Fire Strike, and my results were better than 93% and 98% of all results, respectively.  I’m assuming that’s good.

Looks fine to me. Each card is different. As long as temps are under control and the card is stable, you are goochi!

why i have the sense that you are low on your oc?

my 1060 goes higher than that  so you should be abble to get better?

i mean look my core and memory and in pref cap im still ok like i still have something to juice out of it

and funny thing is look at the temp and the highest is roughly 58-59c
