Zotac GTX 1080 Ti (AMP Edition) 43.94mh/s - low hashrate

[ertank]

I finally understood all advises. It is only after @sarmagedon own OC sharing.

Now, I can run my card stable at 47.48MH

It is not stable if I increase core up to 190. So, This is the best I can approach to 2000mhz core speed.

I am still on T-Rex miner as I checked my frequencies in console. I am just not sure if that “kernel” argument helps. I left it there for the moment.

Now, I am going to test different mt values, but I suspect there will be much difference.

I understand that my card cannot do more than this probably because difficulty of ETH mining and other factors that I do not know.

One thing that I cannot still understand is, All 1080 Ti chips are produced by Nvidia almost same. So, what makes a card to be “high end” or “low end” as long as chip is the same?

As far as I see, “high end” cards can still do 49MH if power usage is omitted. Not my card though.

Thanks.

All those cards are working within NVidia specification (think Founders Edition cards). Since some chips contain less impurities, they respond better to OC and manufacturers (3rd party) usually mark those models as OC or Gaming. They all sport higher then reference clock and memory speeds. Zotac minis most likely are better quality chips with tiny cooling solution since they are similar to Founders Edition in performance but enduring higher temp and slight OC. What we do here is abuse them to the limit outside their specification. If you ran them on Nvidia stock speed they’ll all perform within margin of error from each other.
There is a review on rx5700 on pcgamer that has that explained quite nicely I think:

Modern microchips are made using large (300mm) silicon wafers, cut from a large silicon crystal cylinder. There are impurities in the wafers used for making CPUs and GPUs, and these can lead to errors or differences in performance characteristics. My understanding is that chips from the center of the wafer tend to be ‘better’ than those near the edge, so they may require less voltage to hit the same clockspeed, or they may run at higher clockspeeds at the same voltage. Chips with impurities or errors don’t fully work, so modern processors build in redundancies and some portions of the chip can be disabled to produce a working chip—but one that’s not as fast as a fully enabled chip.

After each wafer gets cut into individual chips, each is tested to determine how good it is in a process called binning. Thus, the best chips usually get sold as the fastest, most expensive parts—the Core i9-9900K, Ryzen 7 3800X, or RX 5700 XT. Meanwhile, the functional but perhaps not quite as good chips are harvested and sold as lower tier parts. Depending on how intensive and accurate the binning process is—and how mature the manufacturing process is—the gap between the ‘best’ and ‘worst’ functional chips from a wafer may be relatively small.

Доброе! Подскажи пожалуйста опыт настройки gtx1080ti.Ошибка разгона в последнее время происходит,случилось все после технической работы в HiveOs,до этого все работало на 150,1400,250ват.Риг больше месяца у меня в работе

[Tbankston]

Can I ask where the 4900mhz number comes from? How do we come to that conclusion?

[frongngng]

Hi I have some problem about 1080ti Zotac
Now my rig not found only one 1080ti zotac and I check that for furmark on pc everything it ok but
Not found on rig plz helppppp

Moring

Now

More info

[Tbankston]

im not sure i understand what you are asking. And your overclocks are all over the place… are you just trying out different ones?

[frongngng]

I am so sorry now I can fix that all good

[jannoke]

For me it came with few hours of trial and error with two totally different cards. It seems to be similar to Hynix memory that needs -1050 underclocks and after certain threshold it will act totally different. This is good to guys who want fairly efficient card without overclocking memory to sky. This also does not need your card memory to have very good cooling from factory (I have one of the 1080ti with free air cooling only , no direct contact with memory chips).

[ertank]

I couldn’t understand what you mean by “-1050” underclock. Does it for memory? For GPU core?
Would you share your OC settings (with captions) to clearly understand what you mean?

Thanks.

This youtube video explains a bit how hynix (downclock) vs samsung (overclock) works on 1660 super cards.

1660 Super - 32 mhs Hynix memory fix! How to Improve Low Hashrate on ETH

I also put it to correct position, but to understand better you should watch the whole video.

It’s memory clock. you can’t downclock gpu -1050 mhz even if you wanted it.

So examining this phenomena further and trying to see if it work on other cards lead me to this 4908 mhz on 1080ti. Just with different clock .

What kind of hashrate are you expecting to acheive?

[ertank]

I already worked on my 1080 Ti and below is all I can get out of my card. These settings below keeps card memory around 4908 Mhz

With below miner options

[SKM]

its for 1080ti ZOTAC mini?

[ertank]

It is zotac mini. Pictures below

Hello! This topic is more appropriate. I decided to try different settings and see the result. Here’s what happened. [trex, ethermine, nvd tablet on -50sec]. outside 25C/77F
inv - do not pay attention, these were problems on the server.
Would like to hear your thoughts? Thank you!

[Rudnikmining1]

Hi can you have a look on mine is well please?
I trying different overclocks and different miners now and still getting similar outcome around 38mh/s on 1080 ti 11gb

Any help or advice will help.
Thank you

See my overclocks here:

1080Ti slower on ETH when overclocked

My settings for MSI Gaming X [image] It can go over 48 but it needs more power at that point so i am keeping it at 46. Using NBMiner with Pill as i couldn’t’'t make it to work with memory tweak. AS much as i like it but not using T-Rex as i have both AMD and Nvidia cards. Hope this helps

[cgoneto]

Will you also know the gtx 1080 memory clock limit?

[kompalol]

Holy shit, your temperatures and rejected shares are through the roof mate!

I definately wouldnt push my cards that much. I can post you my cards. Look at my fanspeed, temperatures, wattage and overclocking. Hope it helps!
