7970 @ 790KH/s litecoin / cgminer

[andeekaii]

Hi Guys,

My first post here. I've spent the past few hours looking around the internet and this forum in particular, for cgminer settings for a 7970 mining Litecoin.

I noticed that a lot of people are struggling to get past 600KH/s and even the people that do were maxing around 730KH/s. I figured I'd post my success at reaching a stable 787KH/s, and best of all my fan is only at 45% so the noise is bearable and the temperatures remain reasonable!

Details:
MSI Lightning 7970 BOOSTED Edition
Fan Speed: 45%
Core Temp: 77
Memory Temp: 78
VRM Temp: 76
GPU Power Draw: 250W (Down from 300W stock)

I would be happy to share my full cgminer and core/mem settings and to help individuals to try and increase their hashrate for a small donation of LTC. Contact me via PM.

Would like to hear more about this.


Obviously your using windows (duh) the console window.
Your also under-volting the core. (less power consumption)


I have been trying to find the sweetspot for my GFX card for a while now and i guess I'm going at it all wrong.


Any how i basically ended up with a basic configuration. Tho changing my gpu clock from 1000 to 843 (500 -> 630Kh/s). The stock speeds for my GFX: Engine 1000, Memory 1375. I guess the card could be called first generation 7970 bought mere weeks after they first were seen in stores.

wow! great! i just got today 6 MSI 7970 Lightning, finished setting them up and getting about 740 each. Now i'm looking into fine tuning. Any advice is more than welcome

I must have ended up with a dud card. I have an asus 7970 DirectCUII, and it maxes out at 520 khash, i have tried every setting imaginable and its never higher than that.

wow awesome result.
Any ideas how to undervolt under linux?
I've added option to cgminer config but doesn't work.

I would love to get your config information.  I was getting 740 for a few minutes but now i'm stuck around 710-720 and i keep changing settings and it only goes lower
