: I know is a few years ago only one question? I hope you can still answer me!

My BIOS Config File: V276-18S.SB is exactly the same as you explained in your presentation Excelent.

But what I cant understand is why musty I flash the same "bios276.rom" according to me no bios update at all that is not an upgrade?

Okay my question is? can you flash bios277.rom instead of bios276.rom on V276-18S.SB?

Just wanted to say thanks for this guide! I just got a 7950 in the mail today and within a couple of hours I managed to go from about 140 Kh/s to a solid 600 Kh/s and only 66 degrees (fan at 56 percent). I know I have more room to play right now but I am at 0.962 v, 1000 Mhz core clock and mem at 1250 with an I=18. No hardware errors. Very pleased and I know this saved me a TON of time!

Now, does anyone know where I can attend a crypto-anonymous meeting, I think drugs are less addicting...

Hahaha np man, glad I could help.

And yes, it can be very addicting Grin

noob question but say i flash a different bios say eg club 3d r9 with a tri x bios would it make it hash as hard

Sorry it has taken me so long to get back to you but I would not recommend that. Flash the bios on a video card, that where not meant for that specific card, could potentially brick it and render it useless.

I'm getting ~638kH/s with 22400 1050/1450 1.025v I18 (MSI set to 1025) but it runs at 77-80 at 85% Fan. I've tried everything that I can think of to still keep the high hash rate but lower temps.
I can't do I20 my gpu doesn't like it, 18 is my max.

Is your miner in a computer case or open?

Had? Did you already get rid of them?

I still got it and I am trying to under volt it.

What are the current settings that you are using? And do you know if the card is voltage locked?

anyone know good volt setting for MSI 7970?

Thank you

Which MSI card do you have? Twin Frozr (http://www.newegg.com/Product/Product.aspx?Item=N82E16814127732) or Lightning BE (http://www.newegg.com/Product/Product.aspx?Item=9SIA3KX16D2328)

What is your current hash rate on the card?

I had 3 Twin Froze and hash not that good like about 1.5Mh/s.

Good deal man, glad to help. Sorry for not mentioning that you need to manually change the voltage, must have overlooked that, I'll be sure to add it.

How is it running after 24 hours?

All good man, awesome.

I've dropped the intensity down to 19, get less rejects this way, I also lowered the gpu-core to 1120 and get a steady 650/660 per card. I had to move things around so have just restarted the rig this morning, will leave it running for a few hours for the numbers to stabilise and post a screenshot.

Edit:

--intensity 19 --lookup-gap 2 --thread-concurrency 22400 --gpu-vddc 0.962 --worksize 256 -g 1 --gpu-engine 1120 --gpu-memclock 1250 --gpu-powertune 20 --auto-fan --gpu-fan 25-85

Thanks for this guide, one thing to note for myself was that I had to manually change the voltage in cgminer/watcher as even after rebooting my rig a couple of times the voltage was still showing stock 1.188. I changed that to 0.962 and it took the change. I'm now playing with the overclock and have it at 1140/1250 @ 670/680kh 73C and 0 HW so far. Will run it for a good 24 hours and see if that is stable.
