My cpu liked 704 better. 
"Note - Uncore setting will now scale with BCLK settings when set to   Auto.  Manual settings will be required when running BCLKs over 220 to   ensure stability and improved BCLK rates.
Note - LN2 Modes might need to be adjusted to improve cold clocking   capabilities.  Auto = LN2 mode 2, setting to LN2 Mode 1 
will result in   potentially better overclocking below -140C. This is dependent upon CPU   quality and cooling. " 
Wish I had one that would get that cold. On my second GT now both 3003B and 3005F CBugged around -110 to -113 I can barely bench at those temps.
Will have to try a 3rd time
