Re: Transwarp GS upgrade article

Andrew,

    You should not modify TransWarp GS, otherwise you risk for the damage.
You don't need to modify to replace RAM cache.  TransWarp GS can only
operate at maximum of 12.5MHz or 14MHz.  You should not modify power supply
or heavy power supply in order to load more amperal current.  It will cause
motherboard to be less reliable.
    TransWarp GS is very stable at 12.5MHz.
