best overclock settings for 6600 (not XT)

[Filippo Tognola]

hello, I have a rig of 6 Sapphire Radeon RX 6600 Pulse cards (not XT), currently I use the default settings: core clock 950; memory clock 930 and core voltage 625. Memory voltage and memory control voltage I don’t have them set.
Currently I get 28.2MH/s per card and 50W of power consumption.
The fans are on 10% fixed, with a temperature of 50°C fixed.
Do you think it’s a good setting or you could do better, especially to preserve the GPU over time?

for non xt i could get max 29mhs more or less. give core 1100mhs you dont need play with voltages it automaticaly decrease it to i liked that option. then switch memory timings to fast and increase memory clock all the way. then you will get more 29. I think there will be new bios for them to unlock memory speed more like on xt version so it will be 32.5mhs in the future i dont know for sure but with AMD it happens always enjoy 6600 with 70watts

I really hate RX 6600. Everything is weird:

1. Setting is total different between HiveOS and Windows. On those system, they looks like different graphic card.

2. Driver almost in beta. I can't read SoC clock in windows, and there is no SoC VDD reading in HiveOS.

3. Setting and result maybe 2 different things, especially in Windows.  

4. If some GPU crashed, windows will hang up in 1 hours, and reboot is not working. You can connect in remote desktop and bemoan.

5. Run slower and slower in period time (pool hashrate).

6. Every time start miner, you may get different hashrate. Or some card could drop it's hashrate when working.

Lot and lot problems here, but no miner developer care, because break through the LHR is hot, and the Big Navi is suck.

In finally, if you can get 28.2M "pool hashrate" at 50W and stable, it's really great.

Find the lowest core clock, at lowest voltages that lets you run max mem that still gets you max hashrate.
I’ve found my cards run aroun 40w indicated at 900mhz core, around 620mv on cv and mv, around 1300mv on mcv and 950mhz mem.

The rx6600xt bugs have been fixed in hiveOS when using Teamred miner now things works very smoothly you can also use others OC settings which is available at the right side of the GPUs settings, honestly AMD cards are pain in the ass it's why most of my GPUs are Nvidia cards

If you set the memory clock to 950, then you have 29 megahash.
To date, this video card has one of the best energy efficiency indicators in mining.
If your video card breaks down in mining, then reduce the memory clock. No other advice.

I can´t confirm this. For me the AMD cards much smoother than my nvidia cards. Only raise the mem clock to 2300 (for my 6600xt´s) lower voltage to the minimum and set core clock to 900. My cards are running so cold and stable with this settings.

Next week i will order some 6600 non xt. Maybe we can flash an xt bios to it for higher mem clocks. Shaders will not unlock that is clear.

Did you see anyone trying to do this?
I have not compared bios, but I think that a video card is easy to turn into a brick. AMD knows about all the steps of the miners in advance, and they probably came up with some surprises.

Hash only refer to how much it can guass in one second, You can get the correct guass in little guass or take ages to get the correct number
This will not be significant if the scale is big enough.

Use hive OS or Minerstat OS, I don't own this card but I have someone who does, the card is hashing at 29.15MH in a gaming motherboard, here is a few setting I find online for Minerstat OS

Miner: Teamred miner

Core clock
900 MHz
Core voltage
750 mV
Memory clock
950 MHz
Memory voltage MVDD
