While computer enthusiasts are generally optimistic about overclocking prospects of ATI Technologies’ latest visual processing unit (VPU) RADEON X1800 XT, such optimism may be too early, as in order to boost the clock-speeds of their RADEON X1800 XT-based graphics cards manufacturers have to use new designs of print circuit boards.

ATI Technologies recently allowed its partners to overclock the RADEON X1800 XT 512MB products from stock-speeds of 625MHz/1500MHz for VPU/memory to 700MHz/1600MHz frequencies. However, it seems that for the reasons of stability the manufacturers have to use newer print circuit boards (PCBs) revision 109-A52031-20 that has slightly redesigned power supply circuits with more MOSFETs. Besides, graphics cards makers have to utilize new BIOS versions that push up voltages and apply some other changes.
