8 pack (Ian Parry) who is one of the best overclockers in the world, with many world records from many different benchmark programs. Well I was lucky enough to spend a day with him last week at the OCUK HQ where he has his own cave for playing in. Some cool (no pun intended honest!), video's here https://www.youtube.com/watch?v=]b5KJ7ATblEc https://www.youtube.com/watch?v=KWh8hD5nW8I https://www.youtube.com/watch?v=1DGJkbxE2Gg I have some more videos which I will leave to later to post! The skill involved and all the meters he has soldered onto the boards/cards to regulate the voltage and speeds on the fly in windows in truely astounding. He was like a swirling tornado arms and hands everywhere. Balancing the temps and ensuring they don't drop too low with too much LN is a skill in itself and he was only doing single GPU card benchmarks, I imagine going tri or even quad SLI would be a major thing to view. Overall very impressed with 8 packs skills and the Antec 1300w PSU. Since that day 8 pack has done some more benchmarking and testing. He has run 2 x R295 cards flawlessly from a single HCP 1300w PSU and yesterday I tested the OC Link out using 2 x 1300w units and managed to smash the world record with 2 x GTX 780tis both clocked to 1825 MHz.
