Got a video of it.
where's the voltage read check points?

you had to take off the plate covering the memory chips on the backside of pcb?

yeah, the ddr5 memory since 5 series repeats the data transfer instead of artifacting like in past cards.

http://www.anandtech.com/show/2841/12

so with powertune for the core and memory error detection for mem, clocking high on the memory is not advised. Performance decrease will not feel like throttling. The performance loss is very subtle. But more importantly, the clocks won't show this happenening. And like artifact testing, you may be showing gains in crysis, heaven, etc., but that odd one game (we've all been there where the 1 random game gives us artifacts) may have that memory transmission.

On the other hand, the core will clock down enough to throttle, so you'll see the clocks go down if you have OSD enabled on afterburner.

You should runs some tests at different memory speeds. Is 1440MHz really faster than 1400? 1375? 1350? 1325? 1300? etc?

Sure I could go to 1450, but the FPS was no different and sometimes worse than 1350.

not sure, I used the ati overclock guide and thats why it landed me on. FPS are about 10-12frames on average higher then stock in dence combat parts (quick glaces using fraps, nothing writen/tested)

What kinda test?

Any 3D benchmark, but preferably a game benchmark such as the one that comes with Metro 2033.

Hey guys ...
So i'm getting 2 Sapphire 6970's ( those with the blue PCB's ) and 2 EK waterblocks.

My questions ARE:

A) what's the max safe voltage for these cards?
B) How different is to overclock a Radeon vs Nvidia GTX card? I can just use Afterburner ?
C) What oc can i be waiting with these cards? I know each card is different but i would like to know, as average results, what to expect

Thanks

Do you have Metro? If yes, see if you can make it thru the Metro bench using the settings in the bench thread in the bench forum. Damn that was repetitive.

Max volts are around 1.3 and up, *edit, don't want you to get the wrong impression. You shouldn't ramp voltage up willy nilly, the lower the better as with all parts in general. When you get to that level you need proper cooling, which you should have. Typically, you'll know you have a good oc'er if you can max it in CCC overdrive. Great overclocks are 1000/1500 memory (getting golden here), very good is 950/1450, out of this world is anything over a great overclock. You can use AB, but there are some AMD tricks you have to do. You can find them in darookie's how to overclock thread. Oh 1 more thing, disable ulps for crossfire.

Voltage measurement points

Yes i had to take of the backplate
