Topic: Help with 7790. (Bounty) (Read 776 times)
guiminer scrypt has been flawless for me, mining 24/7 with 2 cards only reboot once a week (usually for updates or something). Its just easier to configure for somebody new, especially if they don't understand everything in the config file. I'm running a 7770 and a 7790. The 7790 performs way better with a 70% clock ratio (at least mine). If I set the clock higher (stock or oc'd) I get very poor hash results. Lots of tweaking to get the 265 outta it though. If he just wants to mine and go, guiminer -scrypt is probably what he wants.
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.

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,
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

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.

Bump?
Go to the BIOS and disable everything not needed for mining. Then look around for memory or address space related options and toggle them.
Just to make sure, use this miner https://bitcointalksearch.org/topic/ann-sph-sgminer-multi-coin-multi-algorithm-gpu-miner-added-marucoin-475795 and Catalyst 13.12
Read https://raw.github.com/ckolivas/cgminer/v3.7.2/SCRYPT-README and see if you overlooked something.
But I'm running out of ideas...

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.

How about
-I 10 -g 3 -w 256 --thread-concurrency 3584
or even
-I 10 -g 4 -w 256 --thread-concurrency 3584
?
I tried this, it just cut my hash-rate in half.-I 10 -g 3 -w 256 --thread-concurrency 3584
or even
-I 10 -g 4 -w 256 --thread-concurrency 3584
?
Well, Windows 7 64bit made no difference either. Still crashed when I try with a higher TC.
Any other ideas?

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.
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. 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 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 will try 7 64 bit. I have a few license keys somewhere around here. If not, I will give debian a try.

I have been trying to use a multipool, but it does the same thing with a doge pool I tried for comparison.

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.

What coin are you trying to mine? is it N-Scrypt?
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?setx GPU_MAX_ALLOC_PERCENT 100
Then it will work.
