ok,it seems like the v5 was overheating a bit....btw,any idea why I cannot edit my own posts in this thread?

yeah,he measured it and it was more than usual,he had to add extra cooling to keep the temperatures at standard levels.anyway,he doesn't have the board anymore,so no further testing can be done-basically,he scrapped the project as soon as he found out that no extra performance can be gained this way,as k7 barton running on a kt333 chipset board gives almost identical performance,and without (potentially) risky mods.
