The Trusty Xbox upgrade is a 64MB RAM installation (total of 128MB) & replacement of the CPU to a Pentium III Mobile running at 1GHz with 256KB of L2 cache (standard Xbox is 733MHz, 128KB).
The cost of this upgrade is about $150 USD including labor, parts, postage costs & bank transfer fees.
After some invistgation I came to the conclusion that Trusty uses a 750MHz processor that is designed for a FSB of 100MHz. The Xbox FSB runs at 133MHz so the CPU is overclocked & run at 7.5*133 or 997.5MHz.
Quality & Stability
Trusty is polite & tries to keep his customer happy which I think is important.
The quality of his work is excellent; the soldiering looks perfect & he even put protective coating on the Modchip joints.
I used the standard heatsinks & put Arctic Alumina thermal paste on the CPU & Arctic Silver on the GPU. I have had the upgraded Xbox for a month, played Halo 2, CoD 3, Unreal Champ, run XBMC with 480, 720, 1080 H264 clips & Xbox has always run stable.
I think this upgrade is for those who want the ultimate Xbox, something faster than the original but if you expect applications that require a Pentium 4 3GHz to run correctly (such as High Definition video files) then look elsewhere than the Xbox.
