SAPPHIRE 100352-4L 7950 getting terrible speeds, 200-300kh/s.

Get it to work better?

[Punkonjunk]

I FINALLY got it all sorted out.

My previously posted settings are still getting me the best hashrates out of anything I've found. if I drop the TC to 8192 and intensity to 16, the machine stays 100% usable at 550/khs for gaming on alternate monitors. Amaaaaaaazing. So amazing. I also work from this rig 10 hours a day, 4 days a week, so usable/gaming is important to me.

For those googling for this shit though, here are all my myriad of trial and error bullshits:

FIRST AND FOREMOST. Pointer trails ruins everything. TURN OFF POINTER TRAILS. everyone should turn off pointer trails. I love them for the visibility of the mouse, but looks like I'm fucked for that with mining.

FINALLY, this card ISNT voltage locked. it just REALLY likes to control itself, and once you enable in MSI afterburner FORCE CONSTANT VOLTAGE, you will be able to reasonably control your voltage, while it may still spike a little, I'm now keeping my temps WELL under 90 with a setting of 1050mv.
My gpu clock is 1104 and my memclock is 1575.

My two CG miner starty bits pulled from GUI's console is:

Usable: (530ish khs)
 cgminer.exe --scrypt -u username -p password -o stratum+tcp://stratum.us.give-me-ltc.com:3333 --gpu-platform 0 -d 0 -w 256 -v 1 -I 16 -g 1 -l 1 -T --shaders 1792 -g 1 --thread-concurrency 8192

Overnight: (630khs)
cgminer.exe --scrypt -u username -p password -o stratum+tcp://stratum.us.give-me-ltc.com:3333 --gpu-platform 0 -d 0 -w 256 -v 1 -I 19 -g 1 -l 1 -T --shaders 1792 -g 1 --thread-concurrency 16384


with these settings, I'm finally stable at or under 86 degrees with autofan. It's awesome.

Thanks to everyone in the thread for the help, too! A whole lot of it was me being kind of a tool. Fucking pointer trails. You have no idea how hard I fucking screeched when I turned it off and suddenly everything wasn't shitty.

One continued problem, though: My GPU spikes from 64% and 100% after it's been at max for a bit, like this:


Any ideas on making that stop? I tried GPU max alloc command, and guiminer just doesn't like that.

[Benny1985]

Easy-peasy 520 KH with very cool temps:

925 Core
1250 Mem
Undervolt to 0.962

I-19

Gets me said hashrate, and between 60-68C stable, and very low power draw (about 175w per card).

[Shaban]

Oh, and make sure you do +20% power in overclocking software

Would this make it run hotter?

Also, my GPU also bounces around from 100% to 64%, didn't seem to effect my hashrate at all though

Minimize the monitoring program, IE GPU-z or afterburner and it will stop. Mine does the same thing when I have the intensity set to 13.

[Kinetic915]

I'm fairly sure running these commands will fix the 64, 100 gpu deal:


setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

[Punkonjunk]

It was the power limit % fucking thing. I discovered later, if my GPU drivers restart, MSI afterburner doesn't reapply my settings, so it loads them wrong. it loads the correct core/mem clock, but it doesn't load the voltage or power limit settings. When I manually take them down or up a tick, apply, and bring them back to normal, they are applied again and work. It's less of a problem now that i'm finally stable, as long as I don't accidentally open a video or game or something hard on the renderer on one of the GPU mining displays.


I'm finally stable at 1.1mhs between my 7870 and my 7950. Now it's time to order another 7950.

I have two of these cards 100532-4L - they look nice on the outside but aren't the best for mining. It doesn't matter what settings, you get no more than 550kH/s and similar WU. The 100532-2L cards are great - you can push them at 650 KH/s with no problem. I would be OK if these gave 600 KH/s, but... no go.

I even tried your settings above, I got the same hash rate for both -530 kH/s

I currently have many, many 4L's and every single one is above 600.  I've gotten a few to 700 with almost no problems.  It's all about the computer and cgminer.

My understanding is that you aren't going to be mining a scrypt-based coin at a decent rate AND have a useable system.  If anything you've read disagrees with this, then please reference it for me. 

550 kh/s is what I would the target hash rate for a stock GPU. 

ol

610 kh/s and computer completely responsive, and two full HD monitors @ 1080p enabled

What does the computer have to do with it? I've tried every setting I could possibly find on the net and then some - nothing. Certainly nowhere close to 700. The fastest hash I have seen is 650. If you have some settings then let this guy know so we can give them a try.

I say computer because you need enough memory, cooling, etc..

Second is the overclock.  Straight out of the box you should be getting 550 with no overclock on I=19.  If not something's up with your computer.
