I need help with radeon hd 7950

[parham_dante]

Try this configuration:

cgminer.exe --scrypt -o http://xxx -u xxx -p xxx --lookup-gap 2 --gpu-fan 100 --temp-cutoff 77 --gpu-engine 1000 --gpu-memclock 1350 --gpu-vddc 1.105 --shaders 1792 --thread-concurrency 21712 -g 1 -v 1 --worksize 256 -I 17

I use cgminer 3.4.2

I tried that but I got error : GPU 0 failure, disabling !!
I must admit that my cpu is AMD athlon X2 dual core 5200+ 2.70 GHz
and I use 2gig ram DDR 2
my board is a gigabyte GA-M56S-S3 with 200 Megahertz bus clock
I want to know that if hardware failure and "GPU 0 failure, disabling !!" are cause by my poor hardware or not ?
and and I also want to know that is it necessary to upgrade my rig or not? 
thanks a lot for taking time

Model of power supply? Is it at least 20/25 amp on the 12v+?

As indicated in the specifications of your power supply the only channel above 20 amp is channel 12V4 + (which is 26amps). So you must to connect the GPU to this channel (only GPU and no other things like HD, other PCI accessories,fan...) otherwise you do not have enough power to handle LTC mining.

This is a table with the power requirements of each GPU:

how do you see the 7950 requires 25amps.

Is it a brand new or already used 7950 you are using here? Myself, I bought a secondhand 7950 some time ago which would crash if the intensity went any higher than 250 KH/s (Scrypt) but after taking the fan off, scraping the manufacturer heatsink material off and replacing it with a professional ceramic (DON'T USE METALLIC!!) heatsink compound I bought for a few buck from the local computer part store it's been running perfectly between 550 - 600 KH/s since. I make it a practice now to de-gunk and replace the compound on any card I get second-hand now.

Did your card overheat before doing the step you mention?

[lorix]

Yep, though it didn't actually get to the point of overheating it would just go into shutdown/bad card.

Which is really weird, but I guess you solve it by thermal paste so it must be heat related..

I want to upgrade my rig and I do not know whether to choose which of these mobos
760GA-P43 (FX) or 970A-G43
and I want to buy a sempron 145 cpu that I know I must flash the bios in order to use the cpu I mentioned
the main difference between 2 mobos is that 970A-G43 has 2 pcie 16x and 2 pcie 1x while 760GA-P43 (FX) has one pcie 16x and 3 pcie 1x
and I want to use 4 radeon HD 7950 and I have raisers enough
my question is that if I use 3 16x-1x raisers my hash rate drops or it will remain the same ,and please tell that what do you recommend ?
thanks a lot

How much physical RAM do you have in your pc? With Scrypt mining you have to have more or less the same amount of physical ram in the rig as VRAM (gfx ram).

Try to write in your .bat file these commands (before cgminer.exe...) :

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
