Catalyst 13.4 screwed 7970, how to sort out?

[kjib]

Forgot to give approx #

GPU_MAX_ALLOC_PERCENT is at 100.
For SHA256 I have Core clock = 1160MHz, Memory clock = 1050 and everything else on default.
For scrypt I typically have Core clock = 1130MHz, Memory clock = 1550 and  -I 13 --shaders 2048 --thread-concurrency 8192 --lookup-gap 2 -g 4 -w 256

This gives around 400K# for scrypt and about 649M# for SHA256.

I haven't had a 7950 or 7970 to play with, but I generally need a much higher intensity for scrypt and have seen gains using less threads and smaller work sizes.

my 6970 & 5850s are at intensity 19 and 7770, 7790 & 6850s are at intensity 17

Hello,

I have problem. Who can help me?

I have mining rig hardware:

• 4x XFX7950 FX-795A-TDJC
• ASUS SABERTOOTH 990FXR2.0 motherboard
• 8GB RAM
• CPU AMD FX8320 8x Cores 3.51 Ghz
• PSU Lepa 1600W

Software:

• Windows 7 SP1 x64
• AMD Radeo HD drivers 13.4 x64
• AMD SDK 2.7 x64
• CGMINER 3.3.1

My cgminer.conf

Code:

"api-allow" : "W:127.0.0.1",
"api-listen" : true,
"api-port" : "4028",

"worksize" : "256",
"lookup-gap" : "2",
"shaders" : "2048",
"thread-concurrency" : "21712",
"no-pool-disable" : true

With this configuration 3x GPU cards running stable. But when I connect 4 card and run cgminer works very bad and turnoff motherboard. But PSU still running.

Who can help me with this problem? Maybe not impossible run rig with 4x GPU's? Maybe my configuration is wrong? Or I forget something to install?

Than you in advance,

With this config you should be able to run those cards, but the problem could be either something with Windows when connecting the 4th card.  I believe I have seen posts on this.

But, it also could be a heat issue.If the cards are not breathing properly, then they are overheating, and your mining is getting shut down.

Hi,

Thought in first time about high temperatures,  but XFX7950 its in design with high temperatures. I thought put on then water block but other mining rigs owners run this cards without problems and same setup. And other owners run more than 4 cards. Maybe this could be risers problems? Maybe I need change risers into powered?

OK try these settings for 7970 cards

change your  -g 4 to -g 2 

if that fails:

run "AMD Catalyst Un-install Utility" :   http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx    (reboot PC)

install 13.3beta3 drivers : http://www.guru3d.com/files_get/amd_catalyst_13_3_beta_2_download,1.html   (reboot PC )

Batch file:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://coinotron:3334 -u XXX -p XXX --auto-fan --temp-target 70 --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192 -I 13 -g 2 -w 256

these settings above work for all my Gigabyte 7970 at a stable 710kh/s

or try your settings for the overclock

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://coinotron:3334 -u XXX -p XXX --auto-fan --temp-target 70 --gpu-engine 1130 --gpu-memclock 1550 --thread-concurrency 8192 -I 13 -g 2 -w 256

1. Your shaders 2048 is all wrong, those are for 7970 cards, 7950 is 1792
2. gpu-powertune, change it to 20
3. Lower intensity to 19

when you set your voltage from 1.250 down to 1.087 you need powertune to keep it stable

give that a try, if it dosent help let me know

1. I did. changed
2. I did. Also changed.
3. Also.

Now I have about on 3 cards 590kh/s is limit over I can't squeeze .

But with XFX7950 I can not under volt It's always keep voltage at:
0. Voltage 1.169
1. Voltage 1.250
2. Voltage 1.169

but in config I set vddc 1.087. I tryed with Trixx, Afterburner no of these program helps me to down voltage.

Maybe I need some different soft?
