here is the chip I will get a shot without the bridge blocking it in a few minutes. and higher res. it is in my rig right now. Stock volts 2d 1.05v 3d loaded 1.2v it will do 700 core with 1.2v.

Yay! I cannot wait to whack a few of these cards. Hopefully they respond like RV670, 1.1GHz baby!

Thankyou jimmyz for allowing me to feel slightly smug about posting this up so early :p:

pic removed for being wrong :)

Please can you measure the voltage at the points marked in green? :)

No problem .044v idle 2d .054 loaded 3d

LOL well...it aint those points for voltage measurement then! What about the points beside the points I marked (for the top two points- the solder points to the right, for the bottom two, the points underneath them?) :)

Here you go.

cool, I will get some better pics today, I am only working a half day, I would call in sick but I need the money for VR's and such:rofl: got alot to do on my review thread to get it up. It would be done by now but I can't resist updating my favorite forum.

The mod is pretty much the same as for HD3k series.
:)

Only in XS is there a thread on how to volt-mod a card before the card itself is actually released.

I love you guys.
