Hd7970 over 700khs with reaper guide !

[romantic1]

set 1: (with core 1080 mhz)





set 2: (with core 1015 mhz)
speed: 710 - 715 khs

If you interested in, pm me ! I will give you the setting ! (If it's useful for you, please donate me  )

nvc: 4PoeERgVTj8eaAUjcxjoRR5zpBYKR8j4xs (in case you want to donate me nvc)

You know, With hd7970, It's nearly impossible to go 700 khs before ! But not now ! With only core speed 1015 mhz you can go above 700 khs ! The temperature is much lower than bitcoin 700mhs ! (From now on, it's true)

You must have at least 3.5 gb ram with windows 7 64 bits to run these setting ! Just message me !

core speed 1080 mhz, mem 1600 mhz, thread_concurrency 21712, 24000 or 28000, aggression 20?

You're saying 3.5 gbs of ram, do you have the thread_concurrency even higher?

What is the speed as reported by the pool (not reaper)?

What is the speed as reported by the pool (not reaper)?

speed pool reported is incorrect, because it is temp@!calc coin with speed instead of. And let see if your 24h coin equal what y have calc

Show your reaper config file text?

I'm guessing its what I put above. Amd had been working on driver fixes for the 7970 that improved performance, I'm guessing they're out now and it finally works okay with reaper

No, driver isn't the problem ! 12.8 or 13.1 is the same !

This is my graph (with two 7970, sometimes I turn them off)

I'm busy right now ! I will pm some of you later !

[maunderingcabal]

Please PM me, I'm interested as to how you do this.

Ah good, now you know you want to buy one of these in .au

help me get more.

OP
post your settings

[romantic1]

Have replied all the pm !

[nethead]

Have replied all the pm !

send me the guide too, if it really works i will donate ltc

EDIT:
got it, but cannot get it to work, it wants higher lookupgap
nvm, i sent you 1 ltc

For anyone trying to do this, they just use a different core:memory ratio (0.57 instead of 0.68 for 7950) and memory overvolting to achieve these hash rates.

Eg core 900 mhz, core voltage 0.975v, memory 1575 mhz, memory voltage 1.6v (stock should hit this, though), thread_concurrency 21712

So does anyone have the settings that will achieve over 700khs?

I can get 760-800 Kh/s using my 5970 with cgminer -scrypt. Costs a lot less than a 7970 too.

Sorry this is not helpful considering the title of the thread and topic being discussed.  I can also get high hash rates on a 5970 but we're discussing how to get the best hash rates out of a 7970.
