Trouble with ASUS R9 270 (cgminer 3.7.2)

[l008com]

I have a pair of these cards, that I'm trying to mine LTC with. All over the internet, you can find people getting 450khash or more on these cards. But not this guy. I can't seem to get anything above 250khash per card.

With my intensity set to 11, I don't get any hardware errors. With it set to 12, I get a small amount of hardware errors. Any higher, and I get nothing but hardware errors. Everyone seems to use an intensity of 19 on these cards. I can't seem to get even remotely close to that

I've tried copying countless people's config. I've tried running everything way down slow, except a high intensity. No matter what I do, the outcome is always the same:
-I 11 (no hardware errors)
-I 12 (an error or two per minute)
-I 13 or greater (streams of hardware errors, nothing BUT hardware errors)

My system is Windows 7, I'm running the newest AMD drivers, my PS is rated for 850w but my system only uses about 350w, peaking at 400w. These are my cards: http://www.asus.com/Graphics_Cards/R9270DC2OC2GD5/
No monitors are hooked up to the cards, my screen is hooked up to the integrated graphics. Oh and I'm running cgminer 3.7.2!

Post your other config settings.

Have you tried hooking a monitor up, think sometimes you can have problems without monitor connected.

I am running my Powercolor R9 270 at 460  Khash with Intensity of 18.

Please check if you have added the two lines below to your batch file or system config. Also post your CGminer config.

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

[l008com]

Update:
I'm able to get the cards up to about 308Khash each, using these settings:

--thread-concurrency 8192
--gpu-engine 925
-I 13

[l008com]

Please check if you have added the two lines below to your batch file or system config. Also post your CGminer config.

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

I don't know what this means. What is a batch file, or system config? (This miner is my first windows machine)

Also, there is a monitor hooked up. It's hooked up to the built in video though, not the discrete GPUs. I don't have enough monitors to give every GPU it's own monitor.

The batch or config file are what tells cgminer to connect to the pool/ run certain settings. How are you starting cgminer?

Your TC is too low.  Minimum TC should be at 10240+. If i run anything under 10k i get HW errors.

I run my 10 270s @ TC 24k.  You need to add that setx GPU_MAX_ALLOC_PERCENT 100 command.

I use a .cmd file which, for example right now contains:

Code:

/path/to/cgminer.exe --scrypt -o {pool stuff} -u {username} -p {pass} --thread-concurrency 8192 --gpu-engine 925 -I 13

I run my 10 270s @ TC 24k.  You need to add that setx GPU_MAX_ALLOC_PERCENT 100 command.

Anything other than 8192 gives me error -61 and cgminer won't start. Even with the `setx GPU_MAX_ALLOC_PERCENT 100` added

if your using cmd, just run those commando first before starting cgminer

-> setx GPU_MAX_ALLOC_PERCENT 100
-> setx GPU_USE_SYNC_OBJECTS 1
-> /path/to/cgminer.exe --scrypt -o {pool stuff} -u {username} -p {pass} --thread-concurrency 8192 --gpu-engine 925 -I 13

I did this. I still can't up my TC, else I get the -61 errors. Each of these cards has 2 GB of memory btw.

Try the older Catalyst 13s..  14.1 was causing trouble with my cgminer so I went back.

I'm on the 13.12 driver package.

Hi Everyone,
I have the same card and im finding my temp's go through the roof as soon as I hit 415kh/s or higher.
Card gives no errors no matter how I abuse the settings. Get great speeds up to 475 or so but heating...
Have awesome cooling, airconned office etc with extra case fan pointing straight at it, so not cooling issue.

Settings im using wich are stable temo of 75deg. @388kh/s
Windows 8.1 using 2 monitors on it. 13.251 drivers.

setx GPU_MAX_ALLOC_PERCENT 100

cgminer --scrypt -o stratum+tcp://url -u u -p x --thread-concurrency 15232 --lookup-gap 2 --gpu-engine 900 --gpu-memclock 1500 --gpu-powertune 20 -w 256 -I 18 -g 1 --gpu-fan 100-100

If I bump up the engine the speed goes up nicely but so does temp.
Anything im doing wrong or that im missing?
Seeing guys running similar cards at 450+ at lower temps etc.

Any advice welcome.
Thanks in advance.
Dave

What are you using to see your temperatures? I've been unable to see these card's temps using any utility I could find.

Also, copying your settings, and I'm finally getting some faster speed. About 405khash each card.

[dangerdave]

The CG miner shows the temp for me :/

Where does it show it? Is there something you have to do to get this info to show up? I've been struggling to get temps off my cards, because I really have no idea if i'm cooking them or not.

[l008com]

The CG miner shows the temp for me :/

Also, what driver package are you using for these cards?

Temp shows in top left corner, simple google img search should show you how it looks with temp
