Overclocking the core works pretty fine but now i want to downclock the memcore.
My problem is: I am not able to go lower than 1050Mhz with CGMiner...
When i try to go to 1000Mhz with cgminer.conf the memcore is set back to 1250Mhz (standard memclock).
So im pretty much not able to go lower than 1050Mhz..which is too high in my opinion.

Greetings.

I have same problem, with my new Asus Radeon HD 7870 1GHz edition. With 50MINER software (DiabloMiner) running in a Windows 7 64 bits, I can go down to 1050 MHz, but if I try to lower more, it goes to 1200 MHz. again.

How many MHash/s can you do with both cards? With my desktop with AMD Athlon x2 4800+ @ 2513 MHz, I get 451 MHash/s with GPU @ 1200 MHz, Memory @ 1050 MHz & VDDC @ 1.1219 Volts (GPU temp=73ºC).

Happy week-end.
