3070 overclocking, it just keeps going higher and higher without crashing, temps at 85c

[AmyTheBun]

Hi, So I was using superposition and overclocking my 3070 and i'm concerened, i keep pushing the core higher but nothing happens, i reached +180 in msi afterburner before i decidec 85c at 100% fan is too much.

i pushed my power limit to 125% (max) and it was drawing 305w. also  AFAIK this doesn't boost voltages right? Id on't wanna reduce my card's lifespan when they cost 2000$ in my country with this madness.

 

my memory was at +750 but i'm too scared to go higher, should I keep trying? are these... normal? why am I not crashing! my old 1080 crashed when I applied anything more than +80 on the core

a safe overclocking is like around +100 on the core and +500 on the memory, of course this will vary by card, but you can try this configuration I said, it should be safer.

and yes as the rule of thumb says, overclocking does make your components wear down a little faster than normal. a safer overclock would maybe maybe consitis of like 
+20-60 on the core and keeping memory +500, lower on the memory is preferred like 400-450

Thanks for the answer ^_^ does the overclock I do now increase voltage somehow? i haven't touched voltage settings.

I realized only now that above 120mhz i get no benefit in perfromance! raising the power limit to 120 onyl gives me like 1-2% more perfromance and makes the card go from 78-80 to 86c 0_0

 

are the safe oerclocks you mentioned likely to reduce lifespan? has there ever been any tests done on this? (where people compare the same gpu with a slight overclock.

 

have you yourself ever lost a GPU early to overclock

Thanks a ton for the answer!

Did you check your core freq under load?

On 30 series cards you're usually power limited so your overclock is basically only active when almost idle, as soon as there's some load it'll hit the power limit and it'll throttle back to normal or below. So basically no benefit.

it seems like youw ere right. I was only using part of my overclock. i realized above 120mhz core has no benefit. however i can get a benefit from my memory up to 1000-1100mhz. but is it okay to keep this? i'm going from 140 to 152fps in superposition.

Yes memory clock can improve things. Do check the memory temp in HwInfo64 if you're worried about longevity, might be better with the 3070 and its GDDR6 but the GDDR6X on the 3080/3090 quickly gets very toasty with insufficient cooling from most boards.

Also run benchmarks when OCing memory. Sometimes it happens that you can get higher clocks and it appears to run well but you are actually getting lower performance.

3070 doesn't have a memory sensor!

I genuinely get better performance until +100 core and +1000mhz memory

Ah welp, just hope for the best then

Heh. Would you think +1000 is safe long term?
