Whats up with my gpu

Hey guys, recent upgrade although not my GPU.
Thing is I thought id overclock my card which is a 1080. Im currently overclocking the memory, stock readings are 1898 for core and 10010 for memory within gpu tweak 2.
As I said im working on the memory but in the app now im up to 10550mhz and havnt suffered any lock ups or graphical glitches. Is this normal for a card to overclock so much considering its a overclocked card anyway. Also within 3dmark its saying the memory is infact 1320mhz n not 1550mhz or 10550mhz. Can someone in the know plz enlighten me a little bit, and tell me which of these apps is telling the truth

Thanks

btw temps of the card havnt gone above 55c
 
it just keeps going I just added another 20mhz and the score on the benchmark I keep running keeps going up

Which is being truthful, or am I looking in the wrong place or getting mixed up somehow?

Thanks

ok I just took it up another 20mhz and it adds 2 in f uture mark, so instead of 1324 its now 1326 but in gpu tweak its 1610. If I get this right that means I can go 50mhz a time and thatll be just 5mhz in reality??

in the process my score has gone from 10220 to 10870

ggdr5x is 10ghz effective so software is fine. The vast majority of 10 series cards do 2000mhz+ on the core depending on power limits + temps.

It is normal for the 10 series to be able to acheive +500 depends on the memory quality. Although ensure to benchmark as scores/performance can start degrading after a certain point.

What it gives you in 3dmark is the actual clock speed vs effective speed in software which you see. Gddr5x for example has qdr mode (quad data rate). Meaning the effective clock = actual clock *2 then *4 or just simply *8.

Or 1324*8= 10592mhz effective

So I can keep going up and expect a problem around the 1500mhz mark in the futuremark reading?? Why are they not matching up? The core is over the 2000mhz with the boost, as you can see in future mark but the memory has me confused.

Edit: ahhh ok so my card shud be locking up or atleast throttling soon then. im now on 10632

Thanks for explaining

Well actual clock = 1324*2

Effective clock= the above *4 :) due to QDR.

There are different ratings of GDDR5X, goes up to 12ghz i believe depending on memory quality. The FTW3 1080Ti has 12ghz effective GDDR5x.

10-11ghz is probably around the norm however. Depends on memory used. Just increase and benchmark to make sure you are not losing performance.

Shouldn't throttle. If the core temp is fine the memory temp will be fine and within spec if you are using a good quality aftermarket cooler vs reference etc. It will simply just start to lower your score, or artifact/crash once you go too high.

Why are you overclocking ? Your CPU is more than enough to handle modern games, as is your current GPU as well at stock settings.

Because I can? And why not? More frames are welcome at all times. but I understand your point.
My card was a gd one when the 1080 was released and cost me 900, was one of the most expensive on this website at the time
obviously nothing to be proud of anymore but hey shes still going fine and wont be dropped until the next generation comes along
im now on 10720mhz roughly, and still no problems

im on 10750mhz n gunna leave it there for the night, temps still not above 55c, cpu around the same using ai overclock to 5ghz.
score in benchmark has risen to 10940 now, its a pretty poor score as ive got a 1080

Thankyou for the help everyone, ill continue this tomoro, who knows I might get to the 11000mhz mark lol

equally, why does everyone assume we all overclock?

the name of the shop is, just that - a name.

I used to overclock back in the day, but I rarely do now. I can't be arsed faffing around with voltages, timings, stress testing. I just like things to work, switch the PC on, do what I need to do, switch off.

So it was a perfectly appropriate questions regarding why bother overclocking on such a high spec system to begin with, especially on GPU memory as it doesn't generally have a massive impact on performance

Ah, but the purpose of the thread is guidance with overclocking.

It’s quite odd, imo, to come into a thread where a chap is currently overclocking, and then question his reasoning and have a debate on the topic. He wants help, so let’s... try to help him?

Anyways, keep going mate. You’ll reach a point where you thermally throttle, or if you’re under water, where you artefact or crash.

My 1080 gets 2160Mhz avg. on the core, with a max of just under 2300Mhz.

The memory has never been great tbh, I can only get about 11000Mhz effective.
