No, I am ashamed to say it is an even crappier heatsink than the one that came with my A64 Venice. It is nothing like the Phenom II x4 one, which is the same as the one that came with my Denmark Opteron 170.
Also, I'm appalled at Gigabyte for their compatibility list for the Phenom II am2+/am3 here.
It says that my mobo is good to go on bios revision F6. F7 is the latest bios, but it was somewhat unstable for me with the same overclock on my Phenom I, so I kept it at F6. So, I put in the new 720 and it doesn't boot AT ALL! I then try resetting the CMOS and retrying. Still no good. So, then I put in the old Phenom, update the BIOS with @BIOS, then reboot, plug in the 720 and it finally works.
With the Phenom II on the stock cooler, I bumped up the multiplier to get it to 3Ghz from 2.8Ghz without changing voltage, so I could do some speed comparisons with my old Phenom I at 3Ghz, both have the ram set to 1066mhz. Well, it didn't even make it through a 3dmark Vantage run without crashing. It's too early to tell if it is the chip, if it needs more voltage, or what (temperatures seemed in check even at 3Ghz load). I'll retry at stock speed and see if there are any issues. I'll report back when I get my Zalman reinstalled.
