Was lucky enough to acquire a AMD 7990 - only getting 200khash/s??? LITECOIN

[Sancho]

So I just installed the card and am only getting around 200 khash/s with cgi miner versions both 3.2.2 and 3.7.2

The card freezes my computer at intensity 13 which was recommended by many sites so I've been running it at intensity 11.

Here is the .bat file.

cgminer --scrypt -o stratum+tcp://usa-1.liteguardian.com:3335 -u Sancho.1 -p x --intensity 11

--thread-concurrency 8192 --worksize 256 -d 0,1 -g 2


Can someone please help me out here? This card was a lot of money and I have no idea how to get it mining at capacity, which should be around 1100-1500 khash/s.

Thank you so much ahead of time!

I guess you are using Windows, to get more than 200KH/s you have to use intensity 20. But you will need to solve your freezing problem first. Sorry can't help. I use Linux.

[Sancho]

Yeah - using windows... hmm, I forgot about the OS - I will try it, thank you.

Edit: Was actually getting almost 1000 khash/s a minute ago before comp froze - with windows 7.


hmmm

GPU mining is not good ATM

Not for BTC.

Yeah, I'm mining scrypt.

[ymer]

One important question before troubleshooting, is your card new or did you buy it used?

[Sancho]

I definitely got it used, ymer. Supposedly lightly.

I wonder if that's part of the problem? Maybe some settings are out of whack? Or maybe it's just fried? Hopefully the former.

I can get 450 khash/s now at intensity 11 and haven't frozen yet - but everything above that crashes me.

[zeraTunerse]

hmmm

Do you have big enought PSU ? Also this freezing happens to me when one of the power connectors going to GPU is burned.

My PSU is 850 watts - should be more than enough, right?

The power connectors should be okay, they are new. But I suppose it's a possibility.

Could the fact that I used two 6+2 pins from the PSU to the card instead of the two 8 pins that came with the card have anything to do with it? No, right?

My hunch is that some asshole sold you a bad card, probably flashed with wrong settings, probably it overheats, probably has some power issue that makes it freeze...

This would sadden me greatly.

change the content of your batfile to include the following
"
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECT 1
cgminer --scrypt -o stratum+tcp://usa-1.liteguardian.com:3335 -u Sancho.1 -p x --intensity 13

--thread-concurrency 8192 --worksize 256 -d 0,1 -g 2

"

[Sancho]

I had it holding steady at 1000 khash/s at intensity 12.

F9, I tried your suggestion and it still crashed. Looked good for a second though at 1400. I was in the process of replying here to tell you it was working when it crashed.

Using the PSU dedicated 6+2 dedicated pins is better than using the card adapter, as long as you have all the power pins populated and your PSU is really 850W it should work just fine, what model PSU is it?

Yes, for 1 GPU 850 watts should be enough.

[Sancho]

Yeah, it's just the one GPU. I wanted to run another with it but it was nvidia and I thought it would be too risky.

My PSU is a Cooler Master Silent Pro M 850W Power Supply with Modular Cabling (RS850-AMBAJ3-US).

I got good results with following parameters


start.bat

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECT 1
cgminer --scrypt -o stratum+xyz.com:3334 -u user.1 -p x --expiry 5 --scan-time 5 --queue 0 --lookup-gap 2 --thread-concurrency 8000 -I 17 -g 1 -w 256

maybe this example could help you....

the red parameters reduced my amount of rejected files a lot....

[F9F0F]

What temp does the card reach?

I'm pretty intimidated about using intensity 17 when 13 isn't working. >_<
I'll try it though.

Are you running Linux or Windows?



F9, I've been trying to keep the temp around 85 if possible. I can't say how high it reaches at intensity 13 because it freezes soon after. EDIT: Although, it just crashed at intensity 12 around 88 degrees. Dammit!

[F9F0F]

Might as well try at a lower memclock and work us upward, try changing it to:
"
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECT 1
cgminer --scrypt -o stratum+tcp://usa-1.liteguardian.com:3335 -u Sancho.1 -p x --intensity 13

--thread-concurrency 8192 --worksize 256 -d 0,1 -g 2 --gpu-memclock 1210
