GPU boost confusion... ?

Right, I just bought a KFA2 2070 super, it has a boost closk of 1815mhz with a one click overclock of 1830mhz if you use the software.

Just plugged mine in and it had a 1900mhz gpu boost, I thought I would try the one click overclock (its literally a butoon in the software) and my gpu boost is now 1920mhz.

?

Ami missing something? i.m not complaining, but I dont get why it's so much faster than it's supposed to be, it's stable as well. just been playing Hitman 2 to test it and been running some benchmarks on loop.
 
Normal behaviour. Based on thermals and power, the card will use headroom to go beyond box specs. It’s partly why with good coolers it’s, It uncommon to extract most the performance without needing to Overclock as the card will already be applying a boost beyond quoted speed.

Been in place for a few generations now and got somewhat more aggressive with pascal and Turing.

Welcome to the wonders of Nvidia's boost system.

My card has an advertised boost of around 1700 on the core but with the power limit maxed out in AB it runs at 1970ish at its hottest (60-62C).

Just seems weird, my old card boosted to the exact figure it was marketed at. annoyingly if you tried to overclock it even a few clicks over it wouldnt have any of it. (gigabyte aorus 1080ti)

Oh well, I will just see this is as a nice bonus, already getting slightly higher fps than my old card at lower temps. another bonus.

Sounds like you got a real potato of a 1080ti with absolutely no headroom if you were only achieving the box speeds of 1683 MHz / 1708 MHz and it was crashing if you added anything above that manually. Probably the worst sample I have ever heard if it topped out at 1708 MHz even with a manual Overclock.

The 1080tis normal behaviour is as your seeing now with your 2070 super and it will like the rest of pascal boost beyond box specs.
 
Yeah down to cooling mostly. My 1080 now sticks to 2150mhz boost under custom water which keeps it at 42c under load :)

with a two fan card on default fan speeds it will boost to 1920 but then it will probably throttle down to 1905 after an hour or so due to heat soak, depending on ambient temps. if it holds at 1920 for over an hour it’s probably just a good chip.

Yep. It was. It was terrible. Im getting rid of it asap.
I think it was the heat. Even at stock it was occasionally being throttled And my case had good airflow.
I had to run the fans 100% constantly when playing demanding games otherwise it would throttle and eventually shut down. I even considered rmaing it but was told it's heat was normal by gigabyte when I first got it.
I hate the card. And the customer service from gigabyte was just as bad.

That's why I made the thread a few days ago about changing. People said I was mad for considering changing to a 2070 super from a 1080ti but already getting slightly better fps, and after I sell the card (with a warning to buyers) I will only pay a little bit for the change.

Rant over.

Had kombuster running for just under an hour so far and it's still holding with temps just under 70.

My last galax/kfa2 card was great (970) so I'm hoping I got another good one. I really don't get why they aren't a bigger brand in the UK.

it’s because the warranty is not as good as other brands. re: boost and temps, you should lose a speed bin at around 70C to 1905 but the firmware for each card is different and if could be your chip may need a lower voltage to hit that boost bin.

Fair enough. Yeah forgot about the 2 year warranty. Mind you I would rather have a card with a lower warranty that works than a card with a long warranty that lasts less than an hour (just had a zotac 2080 die within an hour two days ago. )

yeah, my galax 1080ti hof has put in a great shift so far. no complaints.

I had a galax 970. It never missed a beat. Fantastic card. Only issue was selling it to buy my gigabyte 1080ti as most people hadn't heard of the brand so got a lot less than I would if it had been a different brand.
Not the biggest issue in the world though.

I do wonder how their customer service is if anything did go wrong though. Because zotac and gigabyte I have found terrible. Keep meaning to go evga again as they had amazing support, but always get lured away. Lol.

I have it overclocked to around 2000mhz now stable, (thats what it hits with GOU boost normally, god this is confusing. lol) just realised in GPUz though that at times it's hitting 2150mhz and staying there during a lot of games, and this is at 63c (which is 20c lower than my 1080ti was out of the box!) . again is this normal?
Getting higher FPS than my 1080ti was getting before now (but that card had issues anyway) but just a worried im gonna damage it or something lol.
not upped the voltage or anything, this was literally just upping the clocks. just seems to have upped them far more by itself.

I never overclocked my 1080ti as it wouldnt ever take any overclocking at all, and never overclocked my 970 really (dont remember why) so gpu boost is pretty new to me. dont really get whats going on.

Sorry for my ignorance lol

Yep, what your seeing is very normal. 2150 Mhz peaks though is very nice and suggests you have done well with the silicon lottery, Similarly temps are in check so all good. Its pretty much impossible to damage the card by just notching up the clock speed with the various protections / restrictions built in. At worst, notching up the clock's too high will just have the card crash to desktop or something.

You would have seen broadly similar behaviour with your 1080Ti, but from your comments, but really sounds like your cooler there was broken if you were 100% fans and still throttling / reducing clock speeds on what should have been a solid cooler.

This page has some more details on boost 4.0 and the mechanics which may interest you: https://www.tweaktown.com/reviews/8738/nvidia-geforce-rtx-2080-ti-review-seriously-buy/index11.html
 
It should really say it on the tin but the advertised boost clock is a guaranteed minimum. ie if your card does less then you can question it as working via warranty etc. If your card does more then its a bonus and as said depends on your system, quality of GPU etc etc etc.

Excellent. Cheers man. I'm just stuck in the past I think where the clock speed on the box was what you got lol.

I got a new case with much better airflow do maybe that would have helped the 1080ti as well but hey ho. It's on eBay now. Someone else's problem soon. (I will warn them about the temps. I'm not evil. )
