Manual overclocking makes no sense on nVidia cards...

[dragonmike]

I'm wondering.
One of my rigs is a 5x1080 (EVGA Superclocked).

Whatever I do in terms of overclocking seems pointless and leads to the same clocks because the cards are power-throttling.

Whether I add a fix offset (eg +100), or raise the curve, I have the feeling it makes no difference at the end of the day because the cards will only boost as far as the (ridiculously low) power limit will allow at the current GPU temperature.

You need to find the reason for the trottleing. Sometimes it can help to reduce the tdp of the card to f.eks 80%. Then each card will draw less power and generate less heat, and can be clocked higher.

Have you got enough powerful PSU? OC in general is very efficient.

[dragonmike]

Yeah I've got plenty of overhead on the PSU (1000W Gold powering 3 of the cards, 750W gold the other 2).
I've steepened the fan curves so the temps are in the 60's under full load.

What I'm saying is it pointless to do a manual OC. The card will boost as high as the power limit will allow anyway.

Unless I'm missing something.

[Heimer]

What are your hashrates? Have you compared them with crypto benchmarks sites?

[dragonmike]

Yep, they're right up there. Which basically seems to support my assumption.

[Nebell]

OCing on Nvidia hardware is fairly easy.

Higher TDP > higher voltage > higher top OC > higher temps
Lower TDP > lower voltage > lower top OC > lower temps
Lower temps > higher stable boost clock
Don't crack up your fans to 100%, it's not good for their life span. I run mine at 70% which makes them rather quiet (depends on the manufacturer).
You shouldn't go above 100% TPD on your cards. Don't touch the voltage. If you go above 74C the cards will start throttling down. Nvidia cards are very temp sensitive.

OC only memory if you mine ETH, lower TDP to 50-60% (check your hashrate, 50% TDP is too low for my cards but 55% is enough).
OC both memory and GPU if you mine a coin which can benefit from both.
Experiment, try this, try that, see what's the best.

I have been working with hardware for over 20 years. It still took me 2 weeks to find the perfect OC/TPD/temps for my 2 rigs.

[dragonmike]

Stop doing so if you have no clue how to do proper OCing while mining.
Let it be to the pro's but don't post bullshit based on your inabilities.

You statement already shows your inability and wrong assumption -> generalize your fault to all others is a certificate every moron likes to get.
100% nobrainer stamp granted to dragonmike

Haha, I would ignore you if you weren't so clueless!

My friend, I'm happy to report I'm on the sixth spot for Time Spy scores on HWbot for water-chilled scores. First if you take my exact hardware combo. Here, see for yourself: http://hwbot.org/benchmark/3dmark_-_time_spy/rankings?cores=1#start=0#interval=20#coolingType=5

I've power modded my card with liquid metal, chilled it with a Hailea chiller, and benched that run with the water at 4C.

I know damn well what the fuck I am doing, you retard.


So, now that we've got this over with, let's get back to topic.

I'm basically agreeing with Nebell on this. It's a fine-tuning exercise, depending on what coin/algo you're going to mine indeed. But for those (the majority on nVidia - except for Equihash mostly) that are core-clock dependent, you'll find yourself power-throttling in most of the cases.

I'm not running my fans at 100%, no, I try to keep the GPU temps in the 60's though (with limit at 79), so fan speed will usually sit around 60-75% depending on ambient.

I've increased voltage limit, so I can be sure there's no problem there, but I've indeed left TDP at 100%. Increasing it will increase clocks a little, but not really worth the while at it'll have a negative effect on power consumption and heat.

As I'm using an auto-switching miner (Nemo's), I found it to be the best short-term compromise. I would probably be able to fine-tune it to be a little more efficient TDP-wise, but tinkering with clocks actually yields nothing as the power limit will kick in anyway.

So because you maybe don't know how to OC your card for mining or if your card is maybe not good for OC you think that OC in general makes no sense for NVidia cards? very interesting

Can you explain me why i get 25 MH/s @ 180W with my GTX 1070 at stock settings and with good OC values i get 29,5-30 MH/s @ 125-130W? That's somehow not confirming your statement, isn't it?
(the same btw. for Sol/s - without OC it takes more power for less Sol/s)

Come on, read my posts again. EThash and Equihash are memory-speed dependent. Obviously they don't fall into the same category.

[dragonmike]

Lol I can claim I'm HWbot master number 1# and now..

Your question reflect a complete different picture of you claim being an OC pro - but it's okay if you need a virtual penis extension.
You are the clueless noob that try hard ..lol HWBot yeah yeah..I'm god. You retard

I've made my case, and I rest it.
Now you've obviously been called out so you're just being even more idiotic by not addressing my points and throwing out more pointless insults. That's going to bring you far in life. Keep "rocking da house" with your 18 GTX1080Ti's and come back to me to talk about your penis extension.

[dragonmike]

I should stop arguing with dimwits, they just drag you down to their level eh. Posting pictures of turds, ad-hominem arguments, insults... How wonderfully mature this place has become.

Go to school kid. You might learn a thing or two.

EDIT: dimwit now ignored.
EDIT2: just noticed dimwit registered in 2016... and he's calling people who were mining back in 2013 "noobs". Epic.

[ioglnx]

Well you are the school kid that proof to be the OC pro and failed to be :-D
Just hit the nerve did I? Oh poor boy

Come on, read my post and try to understand - i wrote about MH/s (e.g. ETH mining) and about Sol/s (e.g. ZEC or HUSH mining) - so also core clock dependent currencies and it's a simple fact that with good OC values i was able to gain higher Sol/s with lower power usage at NVIDIA cards.

About what category you are thinking now where OC wouldn't help? At least not the most common

[dragonmike]

I'm not saying o/c wouldn't help, I'm saying manual o/c doesn't (i.e. increasing clocks like +150 for example). GPUboost will basically go as high as it goes given the TDP, voltage and temp limits you're setting.

I've got two 7xAMD RX570 rigs mining ETH. I've fine-tuned them with special memory straps, undervolted the GPU cores and found a good clock+mem speed combo that will give me 28.5 MH/s + 710MH/s DCR.

On Pascal cards however, I've found tinkering with core clock speeds pointless (because of the behaviour of GPUboost).

lets us try to understand you a little better.

How about this.  

5 cards  do what in mh for eth.  

what are you exact clocks

what is your exact tdp?

what do you draw at the wall in watts?

what is you power cost?

I understand the idea of maxxed mh for a card means more coin.
It seems that is your method of mining  getting max mh  and not caring at all about watts.
Am I correct?

You proved already that you have no clue about manual o/c NVIDIA cards, no need to repeat your alternative facts

The facts which can be measured and proved show that you gain performance and lower your power consumption with good manual O/C at most (i guess nearly all beside yours of course) NVIDIA cards.

I'm trying to strike a balance.

Not mining ETH as I have 5x 1080's (non-Ti).

Clocks will usually move between upper 1800's and upper 1900's, depending on load/algo. They will regularly hit power limit and throttle down.

TDP @ 100%

1050W at the wall for the rig

$0.15 per KWh

As said, trying to strike a balance to get max coin at "acceptable" power draw.

Wasn't it you who said he is pro of OC and enrolled his virtual penis extension of HWbot claiming how cool and good he can OC .. rofl you are one in a million turd.
