Advice for 6800, 6800xt and 6900 xt OC settings

[Kujko]

Thank you for the fast reply - i have set it to my 6800XT and try it. Hope this works fine for my MSI card

[yashveeer]

Can anyone confirm the hash rate of RX6600 and RX6800 are optimal? or can it be tuned more ?

[mustafayuzuak]

I don’t know 6600 but 6800 is super

Can you post your Settings for your 6800 please?

[yashveeer]

sure

Which miner would be helpful as well Thank you!

Teamblackminer v1.22

Hello,

I don’t think the reported hashrate from TeamBlackMiner is accurate at all.
There is a lot of stales and some rejected shares

I gave it a try for a couple hours but it’s not as stable as TeamRedMiner or Gminer for nvidia cards.
I had to remove 400 Mhz on memory on my 3070 for TBMiner to start without a crash, it’s just way too agressive on intensity settings

I don’t think 65MH/s is realistic tbh on a RX6800, maybe in windows with ultra agressive OC and MorePowerTool, but it’s pbly not stable.

Reported hashrate increases but not not mean, it’s just BS
If it was for real you would have 10 videos on YT already …

Oh I checked it just now you are right.
What miner should I use? and what OC you suggest?

[momo971]

For Amd cards I would say TeamRedMiner is the best.
For Nvidia Gminer / T-rex are nice.

You can always use 2 miners in a flight sheet for mixed rigs

I posted my settings along with others in this post (RX 6800):

RX6800 - Efficient Overclocking

You could try to add SoC VDDMax @ 850 or 830 [image] [image]

Grea also has some nice posts there.

RX6800 - Efficient Overclocking

Upgraded the kernel with hive-replace to #140, then upgraded to the latest HiveOS version 0.6-211@211029. At my baseline, with no scripts, and no aggressive overclocking, power consumption is up when they were all under 100w, but they are shockingly similar in performance(GPU2 always runs hot in this system): [Image 10-29-21 at 9.20 PM] Edit: Upgraded (4) rigs. Baseline configs, no scripting, and not one of the 4 brands of 6800s is running less than 61MH/s. Where was this combination of K…

It would be nice if 2miners could update their blog post from last year

Best Ethereum Mining Software for Nvidia and AMD

Okay Ill try these settings. I am getting 62.28 on Gminer

I already have two miners in my flight sheet.

Here are some settings for the Radeon family. All reference cards. Finally found stable options. I get the best numbers on NBminer. One issue I encounter sometimes is after a restart, the 6800XT might register ~0.3mh/s less. Also updating settings on the 6700XT on the same rig messes up with the 6800XT. But these settings are proven finally. Just keep in mind all cards are different (even if it is the same model)

thank you, my 6800 now 61,3 mh/s and 110 w

[mustafayuzuak]

I don’t understand, the setting I made for 1 card decreases the mining hash of the other card.

[mustafayuzuak]

First 6800 increased, 6800 xt decreased. Now 6800 xt increased, 6800 decreased.
Every time I change the setting, the mh power of the other card decreases.

[Maahhnian]

Are you on the newest kernel version and os?

[Albinoball66]

Thats my settings they wood work good.

[mustafayuzuak]

Yes, reinstalled from latest image and updated…

[mustafayuzuak]

:((((

[mustafayuzuak]

Now it is better
365 MH/S

[Maahhnian]

Great!
Otherwise try MEM 1066 ore 1069
