Do you use Windows MSI Afterburner to undervolate the 390? What is the undervolate level? What is the maximum you can do? Is that over -100 mV?

Yes, afterburner. Maximum is -100mV on both cards.

How much is your power consumption for the XFX 390 cards? What is your clock frequency and the power consumption read from the GPUZ?

I did a test, took one old s775 mobo with E8400 + 2 x 2GB DDR2, slammed in two 390's (8GB each), laptop hdd. PSU is not rated corsair CX750M, voltage 228V. Windows 7 x64. Asus has hynix memory and xfx elpida.

Clocks 1125/1500, limiting factor is core. Memory controller load is max 80%.

From the wall:

idle ~100W
mining 680W
mining -100mV 580W

Hashrate ~~30MH+~~ ~~30MH-~~ around 30MH/card. Block

.

How do you find the memory controller load? In which software?

In GPUZ, what is the power in and power out?

What is the temperature? When you use -100mV, does it work at 1125 MHz? Do you notice the change if you change the memory frequency from 1500 to 1250 or 1000MHz?

Yeah, I noticed.
It is drawing exactly the same power as my new R9 380X (150W) and the hash is the same - 20MH/s.
Core/Mem freq are +200 now to 1402/3601.
Maybe there is a coolbit option to enable under/overvolting?

Speaking of which - I am not able to find a way to undervolt my 380X card in Linux...
Gone are the days when you could mod the BIOS with tools like VBE...

You are right, there is some false information floating around on these forums. 20-22MH correctly tuned takes exactly the same wattage on both platforms. Pump up the mem if you want to see where strix really goes, 4000MHz minimum, +20W.

It takes some kind of voodoo to make gpu tuning work in linux imo but when that happens there is a nice reward.

Where I live you can find 390's openbox at ~260€. They overclock & undervolt (well I only have two) really well.

Hi antantti
I guess you are on Windows since you can undervolt your 390s? If you are in Linux then could you please share with me how
to do it?

Yep, right now my mining rigs are all windows. Last time I needed to undervolt amd in linux I had to flash bios.

The main reason I do not use Linux is that it does not have many support software. I use MSI afterburner a lot to control cards.

The Ethereum price has droped from 0.031 to 0.021, that is about 30% drop. Last time, during the correction, the price dropped from 0.017 to 0.008. We may have more to drop.

i doubt it will drop under 0.015, and in any case it is still profitable to mine, around 0.01 or a bit more per card

If the price is above $3 and the difficulty does not rise. It is still profitable to mine. But the profit is marginal.

Now is the time to mine, I can see people kicking themselves in a few months for not taking the time to get it all set up

There is risk in building the new rigs. If you build the new rig and the difficulty rise and the price drop, you cannot mine at more.

this is because you need to oc the 970 because they are more limited in the access for the memory(i don't remember now) when mining ethereum versus amd

wow 2k eth, for how much?

1 btc which i think at the time was around 500 usd .. Grin

Had to be the best investment i made so far in crypto But i havent sold so i guess unless i was to do that then i cant say definitively but i feel we have much more upside to go.. I was nervous it was going up way to fast.. needed to consolidate for a bit.. then the next push can start...

Have any of you solominer's or pool's for that matter seen this issue yet.. And do any of you in the "know" have an idea when we will get binaries with this fix in it..
