Hi,
I have an issue. I have a 7790, however, I can not get the hash-rate above 125. If I set the intensity above 11, all I get are HW errors. Also, I have not been able to set TC to more than 3584.
Here is my start line: cgminer --scrypt -o xxxx:xxxx -u xx.xx -p xxxx -I 10 -g 2 -w 256 --thread-concurrency 3584
I am running Memory at 1500, and core at 830.
I have a core 2 Duo, and 1 GB of RAM. The card is directly in the PICE slot.
Thanks
Matt

Search here for your card and perhaps you will find some good settings https://litecoin.info/Mining_hardware_comparisonTry -I 18 -g 1 -w 256 --thread-concurrency 8000

Thanks, that's what I did. However, if I set the intensity above 11, I get all HW errors, and TC above 3584 causes this: [2014-03-27 19:42:22] Started cgminer 3.6.6 [2014-03-27 19:42:22] Probing for an alive pool [2014-03-27 19:42:23] Pool 0 difficulty changed to 64 [2014-03-27 19:42:24] Network diff set to 9.3M [2014-03-27 19:42:24] Error -4: Enqueueing kernel onto command queue.

open a command prompt, (Run > CMD) and then run this:
setx GPU_MAX_ALLOC_PERCENT 100
Then it will work.

Just tried that. No difference. Any other ideas? Thanks

What coin are you trying to mine? is it N-Scrypt?

I didn't notice your system has 1 GB RAM, which may interfere with high thread-concurrency. What OS are you using, version, and is it 32 bit?
You can always mine a coin with a different proof-of-work than scrypt.

I am using Vista 32bit.
It does not seem like a RAM issue, because as it is right now, cgminer only uses about 27 MB of RAM, and I trimmed down vista so there is over 512 MB free.
I have been trying to use a multipool, but it does the same thing with a doge pool I tried for comparison.

Yes, cgminer uses low amount of ram when working, but at startup either the videocard ram has to be visible, or scrypt requires a very high peak RAM usage, or lots of address space is required. I really don't know which one of those, but I've read plenty of unconclusive discussions about system ram needed. I already mined with Windows 7 64 bit on 1 GB RAM and it worked. I suggest you upgrade or dual-boot with a 64 bit OS, Windows or Linux, and try again. Perhaps find a cheap used 1 or 2 GB RAM stick, I dunno.

I had read threads with people running 4x 290s on 1 GB, so I thought it would not be an issue. I will try 7 64 bit. I have a few license keys somewhere around here. If not, I will give debian a try.

How about -I 10 -g 3 -w 256 --thread-concurrency 3584 or even -I 10 -g 4 -w 256 --thread-concurrency 3584 ?

Well, that OS is gone. I have 7 installing right now. I will let you know when it's done though.

I tried this, it just cut my hash-rate in half. Well, Windows 7 64bit made no difference either. Still crashed when I try with a higher TC. Any other ideas?

Nothing in the BIOS. That miner did the same thing. I'm using 13.12. Any other Ideas? ALSO: I'm going to add a bounty to this. If anyone can get my hashrate above 200 without hardware errors, I will point the card to a pool of their choice for a week. I know it's not a lot, but it's what I can offer.

first off your new, ditch cgminer. A lot of people may say im wrong but start with guiminer. My 7790 runs @ 875 core 1750 memory 265k 24/7 never over 70 degrees. Get guiminer, input your info and try 800/1500 thread concurrency 8000 worksize 256 1 vector 1 gpu thread and see how it goes at intensity 16 if your monitor is running off it. Make your you have the latest non beta drivers also, not more than one overclocking software present (trixx, afterburner etc). Trixx is much more effective than afterburner on my 7790, afterburner screwed me up a lot. Report back. edit guiminer-scrypt

Guiminer is just a front-end interface for either cgminer,cudaminer or pooler's cpuminer. Guiminer is buggy and gives false readings or freezes. Hi,

Have you tried to make a conf file? You can enter more options and fine tune it. Usually 4GB works best in my personal experience, 64-bit or 32-bit OS. Just nice overhead to have just in case the system needs it. Don't the 7790 core OC to 1Ghz easily? TC could probably run better at 8000~8192 and gpu thread at 1 (-g 1). Gpu thread at 2 (-g 2) works good on the 5970, 6990, 7970, 7990, 280x, 290 and 290x.
