Overclock benchmark scores all over the place?

[BaidDSB]

Using Unigine to benchmark my 3070 overclocks. i settled on an overclock which is stable. now the minimum my gpu temp stays is 43C. so i wait it its stable at 43C and then run a unigine benchmark.

 

One score is above 4600, one is just above 4500, one is 4567... it jumps all over the place.

 

are benchmark scores supposed to be this inconsistent or is something wrong? the OC never crashes once so thats a good thing.

[Kilrah]

This is only 2% variation, within margin of error.

 

But too high an overclock can also cause unstable performance without an outright crash especially on memory.

[Pixel5]

beside that your possibly have a VRM temp issue as is common with the 3000 series this could all be normal variation.

What benchmark do you run? SUPERPOSITION 1080p Extreme or what?

Preset Extreme or Basic? I also have a 3070

Extreme. 8x anti aliasing full-screen system (1080p)

I just ran Heaven 3 times. Here are my results. They are very consistent. Maybe your CPU doing something in the background?

1) what's your ambient temperature? 

 

2) I always have wallpaper engine running, can that affect performance?

 

3) tell me your exact settings of unigine

 

4) what's your overclock? My card just won't go 95 core clock boost.

 

5) does ram affect the benchmark? I have 32 gb cl16 3000mhz trident z

My Heaven benchmarks are all over the place no matter what GPU I use. 

 

The bench uses one thread to feed the GPU so any interrupts do upset things. 

The GPU I have that is close to performance as yours is a 2080 ti and at 1080p, extreme, 8x AA and ultra quality I got, 5011, 4919 and 4975 all with the same GPU and CPU overclock.

 

I usually run 3 and take the best.

what i dont understand is why the guy above me has nearly 300 of a better score than i have. i top out at 4520's. and i have the better processor [5600x]

GPUs with the same name are not equal.

My EVGA XC3 Ultra 3080 ti has no chance against my MSI Gaming X Trio 3080 ti and they would both loose to either a EVGA FTW3 Ultra or ASUS ROG Stix. 

 

I got what I could get and not what I wanted. 

I am just happy to have cards.

1) Ambient temp is 22. My max temp is 55, fan NOT running full, but approx.with a maximum of 30%

2) Your CPU should be able to handle it, try to shut down everything that is not necessary. Try to download HWiNFO and look under GPU and Performance Limit, here you can see what is limiting the GPU (Power, Thermal, Voltage. etc.)

3) API=DirectX 11, Quality=Ultra, Tessellation=Extreme,Sterro 3D=Disabled, Multi-monitor=Disabled,Anti-aliasing=x8, Full Screen=Yes, Resolution=System (1920x1080)

4) I use MSI AFTERBURNER. Power Limit=110, Temp limit=90, Core Voltage=+75, Core Clock=+220, Memory Clock=+1200

5) I use 16gb ram, 32gb should not matter.

 

Remember that I use water cooling on the GPU's processor and on the GPU's ram. 

 

I think I have been lucky and got a good GPU, my graphics card is not that wild, it is an ASUS RTX 3070 TURBO Before I water cooled it I could overclock almost as much. It just made a lot of noise, so I put water cooling on and then it was also a very fun project

 

How did you overclock your card?

Ya my Ambient is like 30 plus my case cooling isn't that great because of my covered desk.

 

I used afterburner for my overclock. +90 and +750

 

Anyway I'd ask you do to one last thing. Maybe do 3 consecutive superposition benchmark in 1080p extreme setting?  

 

My score is about 9040-9088 in my tests with my overclock.

 

I'd like to see what your card is capable of

[MartinLJN]

It's no problem, here are my tests. Max core Clock 2205 Mhz, Memory 8200 MHZ

thanks. my card caps out at 9100 and it never touches even 2000 mhz. oh well. thanks a lot for your time

[MartinLJN]

How is your overclock set? The Core Voltage kan be tricky, I was power limit so I turn down the core voltage and the core clock went up. 
 

Try to download HWiNFO and look under GPU and Performance Limit, here you can see what is limiting the GPU (Power, Thermal, Voltage. etc.) keep it running when you’re running benchmarks. This will tall you if you’re  thermal throttling, if not then you cooling it fine.

core voltage on the afterburner is greyed out.

here's my core voltage and thermals etc in a benchmark i just did https://i.postimg.cc/rFzcvVnh/Desktop-Screenshot-2021-10-02-10-29-39-08.png

what do you think?

[Dr0y]

Quite an interesting discussion ...

 

When OCing memory remember that GDDR6 have error correction which will affect performance negatively before you reach the point of artifacting or crashing ... the highest memory clock before artifact/crash is most likely not the sweet spot in performance for memory OC ... on my 3060 it crashed at +1400 (never saw artifact) but the highest score I got in port royal was with +925 on memory ... everything higher than that lead to lower and lower score ... also port royal score were really consistent between one run and another ...

 

As for the core I was able to get +175 to pass in port royal, superposition, timespy ... crashed in heaven ... I had to dial it back to +160 ... passed all the benchmark I usually do ... crashed in horizon zero dawn ... final OC stable in game was +130 on core and +600 on memory just to be sure I would not crash anywhere. 

 

Hope that sharing my experience helps a bit and that it wasn't too annoying or misplaced.

how TF is a 3060 getting +130 core while i cant even get +90 on a 3070?

no idea ... but my guess would be temperature related cause I got less core than you, smaller die I think or something like that ... silicon lottery maybe ... there's a lot of things that could influence that ...

whats the temperature in the place you live and what's the max temp your card reaches on any benchmark?

Every chip will behave differently, and also importantly every card model will have different targets and headroom. I don't recall you mentioning what exact card brand/model you have.

 

I can only get +30 on my 3080... but it's a heavily factory-overclocked one already, so it's to be expected if they did a good job of it.
