Hey all. The mac pro 1,1 seems to be getting a bad rap these days, but I picked one up a month ago and have enjoyed it since. It came with a 4870 (now a 6870 though) & 4 GB of ram. It was originally a 4 x 2.66 GHz model, but I picked up two 4 x 1.86 ($200 on eBay, effectively making it an 8-Core), which I have successfully overclocked to 2.33 GHz using the BSEL mod... for an astonishing (IMHO) 8900 GeekBench result. When I run Geekbench on the stock system, it returned a 6100 result. A pretty nice increase. (I'll post screenshots tomorrow) A few notes: 1. Quad channel does make a difference in 1,1's, by a couple hundred points in GeekBench. (This means 4 matching FB-DIMMs in the first upper and lower two slots) 2. Windows 7 64-bit installation was tricky, but not impossible. 3. I have successfully used the 6870 just using the drivers avail for download. 4. I can't find a way (other then looking at the Geekbench results) to show that the chips were overclocked to 1.86 GHz in Mac OS X, but it is easy to verify in Windows. Overall, I find it to be a pretty high performance machine. Does anyone know if Lion drops (official) support for the 1,1s?
