overclocking above 1.4
I've been experimenting with a heatsink to see if the tegra2 can go above 1.4 on the gtablet, but I need a kernel to let me try. If the problem is heat related as in some cases. It should be able to handle 1.6. Thanks for your time and all your hard work.

The Tegra 2 can do 1.6 comfortably. In fact, Clemsyn offers a 1.6 flavor. However, it is hit or miss by user in regards to stability and SOD. Some tablets prefer Pershoot's kernel and others prefer Clemsyn's. I remember there was an illusive 1.7 floating around back in the days of VEGAn-TAB, but it proved to be way too unstable. A heat sync is not needed for 1.6, unless I guess you set the min/max at 1600 and used a performance scaling.
You can OC at 1.5ghz using the 1.6ghz OC kernel, use setcpu to undervolt and OC to 1.5. No heatsink needed.
I cant seem to find the 1.6 kernel anymore. If you know where to find it it would be a big help.
What ROM are you using? Froyo, GB or HC? The kernel is different for 2.2, 2.3 and 3.0.
You are better off flashing the combo ROM which support 1.6Ghz
Froyo ............. FrankenTAB RC 1.0
Gingerbread......VEGanTAB 7.1
Honeycomb.......Flashback
Use SetCPU to OC and undervolt all speed above 1ghz by -50mv

antutu record
Thanks to XDA developers and my past overclocking CPU 's. I can now say I have the record for g tablets using antutu benchmark. Thanks to all!
I have it running stable @ 1.7Ghz. I undervolted all steps down 150mv so I would like to try 1.8 at 1.5v if anyone knows how to write a custom kernel. I want to push the G tab to the limit. Thanks again for your time.

not yet. its on my list (to pick apart dvfs/nvodm and backport AOSP's frequency scaling, etc.).4
