RTX 3070 Overclocking

[SkillTim]

We all know it's risky going over 2GHz GPU with Ampere. But what can be expected with Memory overclocks?

 

I didn't realise until I install it that the 3070's Memory frequency is substanially less than the 3080's (7000MHz vs 9500MHz)

 

Feel free to post your 3070 overclocks showing GPU and RAM frequencies. Here is mine on day one.

Nah it's fine now! You could try GeForce Experience's performance tuner for GPU overclock

[FloRolf]

Well the 3080 has Gddr6X while the 3070 only has gddr6 AFAIK.

Is that the Palit 3070 Gaming OC? Mines arriving today - what is your first impression of the card?

2000MHz (16,000MHz/16GBps effective) is a walk in the park with Samsung ICs. Check GPU info here: https://www.techpowerup.com/gpuz/

 

If it's anything else then sell the card and use the money to feed the homeless or something. Hynix and Micron barely OC at all to be worth the effort.

Palit 3070 Gaming Pro (non-OC). The OC only has a mild OC anyway. Downloading the app above makes it so easy with OC scan. It automatically said 1925 and 7200 was fine so I pushed it more.

GPU-Z says Samsung Memory, sweet.

[SkillTim]

Thanks for the Memory info. I haven't had it crash overnight at these settings. Concerned if I can go further because I'm at 100% Power usage.

[Bobbysixjp]

I think you also post on Overclockers UK? I managed to push my 3070 to 1000 Mhz for memory, +9% on Power limit and 136 on the core. It is consistently hitting over 2000 MHz during gaming. Overall, I'm pleased with it.

No I'm not on OC's forum. I followed the whole thing yesterday and the day before on there. Bought mine from they because I needed something Ampere to replace my 960. Thanks for your OC info.

I've read that the Samsung ICs crash at 8500MHz. Seems that in testing there is a bit of a Memory bottleneck so I'm going to push that the most. I also don't want to push my GPU much past 2000MHz. Looks like I can run 24/7 at GPU +121MHz (2055MHz boost) and MEM +1419MHz (8419MHz). This is also a four times ratio between the clocks. Nice. Levels out at 69C as well. Double nice.

 

Here's a pic of my rig too.

Are you adjusting the Power limit at all? And why don't you want to push past 2000 MHz?

[SkillTim]

I remember seeing a video where it was crashing between 2100-2150MHz. Set power limit to 105%

And are you getting MEM +1419MHz? My card crashes with anything past 1150. 

[SkillTim]

Use this to see which brand of Memory you have. Apparently, Micron and Hynix suck and Samsung is better.

Just checked - it says Samsung memory.

Sucks that you buy an OC card and it doesn't OC more than a non-OC card. Still good though aren't they!

[SkillTim]

Thunder Master doesn't display my memory correctly. It's off by 200MHz. I've crashed two times with higher than this. I'm sticking with:

GPU +113 (2055MHz)

MEM +1210 (8210MHz)

Power 100%

Well that makes sense - I was worried for a bit thinking I might have gotten dud memory. I’ll try +1210 and see how that goes.

Hi all,

 

I have a Palit 3070 GP (non oc). Can someone please tell me what gpu voltage offset does in thunder master, I’m very new to this so I’m not sure.

 

So far it runs fine at +150 gpu and +1000 memory, and doesn’t get over 62 degrees C. In doom eternal I consistently get around 2100mhz on the gpu, occasionally boosting higher. This is with power target set to 113%.

 

I have had it run at +202 gpu, which will run benchmarks but not gaming as it occasionally boosts to over 2200mhz and crashes.

[SkillTim]

That's sounding pretty good. Mine is mining so I haven't checked for games. I would stick with 150MHz and 1000MHz. That's kind of the stable limit for that card.

[oplix]

I don't know what you mean "risky above 2ghz" my Zotac 3070 is at 2150mhz with zero stability issues.

 

+100 core offset, 110% power limit, +800 memory offset

Hi SkillTim

 

Sorry for resurrecting this somewhat old thread but I think that this might be interesting, also for others.

 

Thundermaster displays the memory clock correctly as Nvidia applies a -200MHz memory clock offset for compute workloads such as mining and CUDA in general. The parameter is called "Force P2 state" and can be disabled with Nvidia Profile Inspector. Nvidia says that they did this to improve reliability for critical calculations but some suspect that its just to promote their professional line of cards for these types of workload. You can find more information, including Nvidias official statement here:

Hope this helps.

Thanks for this info. That explains it. I dare not change it from default though if there is no major improvement and risks program crashes. I've learnt that a stable system is better than a faster system.

[unboxgeeks]

I revive this one, since it has lots of useful input, so Palit 3070 Gaming Pro edition, you guys think its fine go 8000Mhz on Memory and 2150 on Core?

 

I did now 7850Hz on VRAM

And boost up to 2075Mhz on CORE (goes to 2075Mhz while gaming)

Power limit %113

 

Is it safe?

 

btw was it proven totally safe OC the memory so much? doesnt it hurt it in long run?
