So long story short i got my 1080ti hydro copper bout 6 months ago, put it in the loop and had just did a mild OC on it and that was that, ive never rly messed with memory even on past cards but was watching youtube video randomly and was like hmm wonder how high mine could go and i started at 100 while Heaven was running and kept going up by 50 every few seconds and then i hit 1000 and was expecting a crash..so let test run twice and no crash, so started up shadow of the tomb raider, no artifacts or nothing. Booted up Shadow of war and ran its benchmark first and then played for a bit and still no crash. So applied core OC of 65 and seems as of right now thats as high as i can go on that. I can probably go on higher if i did the MSI locked voltage of 1093 as a poster posted on here in a guide but anyway, question i got is, is 1000mhz safe rly to use lol? Didnt expect it to be stable like this and with a core OC to boot and voltage only uses up to 1050, ima mess with it more later and see how far i can do core with the memory but highest memory ive seen online was around 650 on the memory and read that going to high can actually make gameplay worse but so far dont see no issues but just wondering.

Safe is all about stability & temps The Hydro Copper should take care of the Temps  Do you see better in game performance or just in benchmark scores ?

Over clocking the memory that high is safe. Memory voltage on the card is locked and not adjustable.
Good card if you can over clock the memory that high and stay stable.
The problem with over clocking the memory so high is that the card has a hard power draw (wattage) limit that is shared between GPU and memory power draw.
This means the memory is taking some of the available power from the GPU and that will cause the GPU to hit the power limit of the card and down clock sooner.
Rule of thumb is GPU MHz is king, memory over clock will really only give you higher benchmark scores, nothing you will really notice in the vast majority of games.
Run some demanding benchmarks with the memory over clocked and without, you will notice the GPU will hit power limit sooner and down clock when the memory is highly over clocked.

Should be just fine as long as it's stable.

Mmm honestly i didnt notice any game performance gain but i also didnt have the OSD on, i was mostly checking for stability but i just got home so gonna mess with it some more and see and do some tests as ive never seen a gpu go full 1000 on memory and be stable. On Heaven bench my score went up 200 points just from memory. jonkrmr

Ya the card throttled down around 47 temp i think it was and was down to 2035 but i have gotten around 2100 before when i messed with voltage so gonna raise voltage to run at 1093 and see how high i can go on mem and the core. Sajin

Ya i tested couple games and saw no artifacts and temps were still good so bout to do some tests and will report back.

here is a screenshot of Heaven running, i run dual monitors so after test i used lightshot to grab both screens and show results. Only odd thing is in GPUz it showed the memory clock not as high but in the msi app it matches up. I also had to lower clock from 2100 down to 2075 as using my profile for the 2100 would cause crash and artifacts, still might have to go lower maybe on core as havent tested games yet but once locking in voltage to stay at 1093 and using Sajins OC tutorial i dont even get temp throttle using the curved profile, idk how that works but noticed that as well. EDIT: hmm seems upload limit is 500kb, trying to shrink down picture without losing quality. Here is link to pic on imgur, hopefully its ok to post as i couldnt upload pic without losing quality and couldnt even see anything since its 2 monitor screenshot. https://i.imgur.com/wKAX3vZ.jpg

Wow! That is very impressive memory you've got right there. :D
And yes, it is safe. You won't harm it any more than usual as the voltage isn't changing.

I just tested Shadow of the Tomb Raider and while in game i had no OC on just power limit and core voltage maxed out and was standing still inside cave and frames were 110-111 and applied the OC and it went up to 123. Am installing 3dmark now and gonna run some before and after tests and will report back. I have paid version but i had to do some email digging to find keys again for it.

Ya it seems that way, ive searched online to find what the avg ppl get is and it seems anywhere from 300-500 with some 600s in there so im happy but in all honesty i probably wont even use it as daily OC as im paranoid it will hurt the card even though ppl said it wont lol.

I can get to about 700 on mine before issues start, 800 gives me beautiful green squares everywhere.

Ya when i ran the Heaven with 2100 and the 1000 on mem artifacts popped up before crashing.

Welp after more testing i left memory at 1000mhz and then worked my way up to the core clock till crash happened then backed it off a little till i could run the benches successfully and final result is 106+ on core which came out to 2100mhz and then 1000+ on memory which comes out to 6496mhz. Passed 3dmark and heaven several runs. I seemed to of got higher scores just from memory cause i was sacraficing memory to get higher core clock which was around 2126 so i just maxed out memory then slowly cranked up the core till became unstable so ya, 2100 was max i could go it seems with max memory.
Also id recommend ppl if u want higher clocks to follow Sajins ( hopefully spelled right ) guide on using MSI to get higher voltages as without that guide i couldnt even go over 2050core before, im still able to achieve the 1000 memory without following guide but core clock suffers a little.
