About my two r9 290x cards ..
-
i wanted to get into the mining forum to ask some questions. I will ask here for now.
i have two asus amd radeon r9 290x video cards …
this is my script i have been running so far:
cgminer.exe --scrypt -o stratum+tcp//xxx.xxx.com:3333 -u username -p password -I 15
my cards are hashing at 630kh/s with temps of 95 …
these cards run fine at temp of 95 and according to toms hardware review they will be fine at this temps … however if i try to hash the full power of these cards the temps rise higher to 97+ and that is when i turn them off . these cards are capable of hashing at 900 - 1000 kh/s … how can i achieve higher hash rate and lower temps ?? do i adjust my cgminer script settings above ??
thanks everyone …

and to Calem from newbie board my two cards are close together on the motherboard which is the asus rampage motherboard … however if i remove a card and run just one i still get the same temps … my case has really good airflow and i keep good air conditioning .

Is that your complete miner script?
Get your self over to [url=https://litecoin.info/Mining_hardware_comparison]here[/url] and see what setting other people have used and their hash rates as a starting point

[/quote]i tried the -I 20 and my cards will hash much higher but they start climbing in temperature too … i am not sure what the other setting do: -w or thread concurrency … to be able to use -I 20 then I need to bring the heat down somehow .

A little more information about your setup makes life so much easier when trying to offer help!
Read the scrypt read me.txt in your cgminer folder all the information you need is in there. Once you have read that then go over to the link I posted and chose a card very similar to yours and try their settings
Your command should look something like this, to give you 700-800KH/s
[code]cgminer.exe --scrypt -o stratum+tcp//xxx.xxx.com:3333 -u username -p password -I 20 -g 2 --thread-concurrency 20480 -w 256 --gpu-engine 1000 --gpu-memclock 1500[/code]
But this is the best I can offer given the information I have

This is outa my league, I’ll leave this in the capable hands of muddy and feathers. +1 rep to both of you. Let’s see if you guys can keep his temps down.

Feathers is right on with the 290X’s. I am running a 290 (non X verison) and I’ve had to do the same thing. Kept at stock fan speed, the card underclocked itself to stay at 95C. I am running MSI Afterburner to control clock speeds, fan speeds, and voltage.
I have my fan run between 55%-63% to keep the card in the low to mid 80C’s. I believe stock on the 290X is 40% fan speed in quiet mode and 47% fan speed in uber mode (that small physical switch on the cards controls which mode it is in - make sure the computer is off to switch modes). In uber mode the card should be able to keep closer to it’s max 1000Mhz boost clock, but upping the fan curve in MSI Afterburner would make it even better.
I can help with MSI Afterburner settings if you need it. I’m sure the Sapphire Trixx program is similar. I chose MSI Afterburner because it has voltage controls for the 290 series (undervolting also helps a lot with heat). I’m not sure if Trixx does.

[/quote]what more info did you need ?? your script did not work for me but i am working on it now .

[/quote]downloaded afterburner … set fans at 63% and now cards read temps 86 and 78 … without any changes to my cgminer crypt my cards are hashing 700Gh/s … i am going to test the cgminer scypt changed to I -20 i am getting between 800 and 900 Gh/s at temps 86 and 78 … looks like afterburner is the win. thanks!

[/quote]800 - 900 hash rates is nice. I get right around 800 with my 290.
I forgot to mention I believe you need the latest beta version of Afterburner to have access to voltage on the 290 series. I’m running 3.0.0 Beta 17.

Did you try asking cgminer to control the fans? Such as:
[code]–auto-fan [/code]
Also you can set a temp target in the config, like this:
[code]–temp-target 75[/code]
I found that the hotter my cards get, the more work is rejected (thats with 280x). In other words higher temps and hash rates seemed to be a false economy.
Also, you’re likely to struggle with those cards in a case. It doesn’t sound like you are using any other form of cooling? A slow, but large desk fan makes a massive difference to my rig… just sayin’ ::)
[b]PS.[/b] I limit the intensity to 13 on the newer cards, as recommended by cryptobadger. Wonder if the 290x is a similar case.
