After reading the article over at THG the other day I decided to go for it and order a new Pentium D 805 etc. to replace my XP-2600M set up. Main components Pentium D 805 CPU Asus P5WDG2-WS i975X Motherboard 2 x 1Gb OCZ PC2-8000 Dual Channel Extreme Edition XTC Platinum Series EL-DDR2 RAM PowerColor ATI Radeon X1900 XT-X 512MB Western Digital Caviar SE16 250GB 2500KS SATA-II 16MB OCZ PowerStream 520 watt PSU Cooling CPU block - Danger Den RBX Chipset block - Danger Den Maze 4 GPU block - Danger Den Maze 4 Acetel Radiator - Austin Mini with 4 x 120mm fans Pump - Eheim 1260 The watercooling set-up uses 25mm ID pipe from pump to radiator and to and from the a custom build inlet and outlet manifolds. 1/2 inch ID pipe is uses from the manifolds to the waterblocks and back. So far I haven't really pushed the system until it fails, but have reached 4Ghz using the same Vcore voltage as suggested in the THG article with no problems at all. Here are some screen shots: Not sure why the Whetstone result is so low, perhaps someone could explain why that might be? Not bad at all for an £80.00 CPU. Later I will push it harder and see how much further it will go.
