12.6+ AMD drivers do not let you change the memory speed of 7xxx (7950, 7970, etc) cards below a certain threshold. To underclock memory, use Afterburner and a dll file.

1) Install MSI afterburner.
...

I have done all this, but I can't go lower than 685MHz on my Sapphire 7970 (Afterburner won't let me).

I use:
Windows7 64bit
MSI Afterburner 2.3.1
Catalyst 13.1

What might be the problem?

All cryptos are FIAT digital currency. Do not use.

It was probably an honest mistake.

Join Slush's pool with any gpu and see for yourself.

ANY 300-700 mhash/s gpu will be easily tossed around when its up against a 3.2+ Thash/s proportional pool.

do you think he sat there and waited for a new block? just so he could bs about it?

crazyates, what is your hash rate at 1050/410? I'm currently using 1050/300 and getting 631 Mh/s. Just trying to compare.

That's a great result! I'm get ~690MH running at 1170/1020.

I know slower mem would drop temps, but MSIA is a PITA. Tongue

I have 692 Mh at 1150/1000.

Ace` on slush's pool gets 725mh/s with a msi 7970...i thought he was bs'in but he did produce a screenshot with miner n clock speed of 1150 dunno how he does it...and that's just with cgminer I9...my 7970 can only do bout 660mh/s at 1150 Sad

Its easy to get abnormally high or low readings with Slush's. Especially right after a block has been found.

My 460 mhash/s 7870 once clocked in at 800+ mhash/s. lol

How many threads, and at what intensity?

Static intensity of 11 appears to have brought me up around 630

630MH/s. 12.8, but with the 12.10 OCL runtime.

What APP SDK are you using? 1050/410 with 12.8 and 12.10 OCL runtime is only getting me around 593 Mh/s

:s im getting 555ish

Hmmm. I WOULD do this, But my hashrate starts to crap out when my memclock goes below 740...

You're using a weird kernel or APP SDK version then. All of my 7970s run at 340Mhz, and the hashrate is pegged. In fact, I'm sure it could run lower (but I don't know how stable it would be).

Play with the settings then. I'm at 1050,410 on my 7970, and it takes a full ~2 minutes to finally stabilize at a hashrate, but it's pretty stable.

yeah, i'm not sure why stuff like that is. the ability to control the memory speeds of the cards has been really wacky in afterburner since 12.6+ drivers. You may want to report it as a bug.

Crazy weird... I have two setups, almost identical... Miner1 has 2x Asus 7970 with an old Intel chipset, Miner2 has 2x Asus 7970 with the 990 AMD chipset. Miner 1 allows me to underclock memory, but miner 2 wont work! I've copied and pasted the CFG files, neither of the rigs has catalyst control center installed, and they both have 12.8... Perplexed...

There is a reason for limiting the underclock...

..if you underclock memory too far you end up with a computer that won't boot up! Grin

How to use MSI Afterburner...
At the bottom are some numbers 1 2 3 4 5 this is where you can store your settings.
There is a tick box to apply your setting at startup (don't tick this until you are sure it works)
In "advance settings menu" MSI lets you switch between multiple cards to change each one and also unlock the safty settings.
