Topic: Trying to make a list of the rx 480's hash rate power and settings etc. - page 5. (Read 42289 times)

GPU clock not mem clock :p

on claymore miner i jumped my hash rate from 50mh to 54 mh   by moving clock from 2000 (stock) to 2200

this is for the 480x  not the r9 390's

FYI you can down clock the GPU core to around 1160-1180mhz...the GPU waits on the memory controller after those speeds so no point running it full speed. Saves a few watts.

It's getting better and better everyday. Good thing I was able to order 30 480s to send to Oregon mines for hosting. The last ones are scheduled for delivery this Friday from NJ but still waiting on USB risers I ordered from eBay. OM is already hosting my 5 5 card 390 rigs.

I got watts way down  with an 84 setting on asus tweak  my watts now for everything are 320  which is a lot better  still stuck with 43-44 mh

but I am liking the 320 watts.

 this rig has 3 nanos without bios modes  cost was 1500   hash was 81 mh with 580 watts full system

it will soon have 4 480's no mods cost 900    hash will be 84     with  600 watts full system

I used ASUS Tweak to lower power limit and increase memory clock to 9000, then closed Tweak. Opened MSI AfterBurner and set memory clock to 2250 MHz and closed it. Saved settings in AfterBurner and checked apply at start up. Reboot computer, and run Mining software. I found that when running mining software opening AfterBurner sometimes freezes the mining software. It's best to apply settings when miner software is not running. Settings can be verified with Wattman or GPU-z. Results are similar to Nanos at stock settings at half the price

looks like you are using gpu tweak  I am using watt man with my 2  sapphire 8gb cards

I will see if I can get to your level.  my watts are about 320 for the cards and 30 for the pc   my mh is 43.


but I never used wattman

  msiafterburner does not work 

sapphire trixx does not work

Getting much better results at -15% power limit and 2250 MHz memory clock. 55.5 MH/s or 27.5 MH/s/GPU from 2 480s for 355 Watts at the wall. MB, CPU (G1840) etc. take about 45-50 watts, so basically 150-155 watt/GPU.

Firstly: This fix is by no means an official one and you will be using it at your own risk. If you for any reason manage to fry your card while using it, you are not entitled to make any claims for warranty exchange (RMA).

As soon as the bios flashing software supporting Ellesmere becomes available, I'll be releasing a modified bios which makes the necessary changes automatically.

The procedure is rather simple, and can be done on any software which supports I2C control on Radeon graphics. Personally I recommend MSI Afterburner for the job.

- Download and install the newest MSI Afterburner
- Go to the installation folder of MSI Afterburner (where the MSIAfterburner.exe is located) and open a new command window ("Left Shift + Right Mouse Click" when no file is selected)
- Additional step: Verify that the I2C interface to the VRM controller is working by typing following command: "MSIAfterburner /ri06,08,0D" (without the quotes). If the response is ": 20" or ":44" you're good to go.
- The two commands you need to input are following: "MSIAfterburner /wi06,08,1E,BB" and "MSIAfterburner /wi06,08,1F,B0".

Once you have given these commands the power draw from the PCI-E slot has reduced and moved towards the PCI-E power connector. The recommended programming value is "B" (/wi06,08,1E,BB and /wi06,08,1F,B0), however you can go set it to anywhere between "B" and "F". Higher the value, more of the power draw will be directed to the PCI-E power connector.

Do note that this fix must be re-applied after every reboot.

EDIT: Added the I2C response for IR3567B controller (0x44).
IR3567A = 0x20.

The fix applies for both!

i remember in another thread, there were people saying that a 390 can do 27MH/180w, it was bullshit from what you are saying phil
