I have a Slot 1 board and have heard about using a Powerleap upgrade or Upgradeware adapter to make the newer Tualatin CPUs work, what would you recommend?
A. It depends on whether your motherboard uses the original VRM 8.2 voltage regulator or the later VRM 8.4 version. VRM 8.4 was released for Coppermine core CPU support, and is present on most Slot-1 boards that support 100MHz bus or higher. Early 100MHz bus Slot 1 boards and most 66MHz bus Slot 1 boards use the earlier VRM 8.2 standard. While VRM 8.4 allows voltages down to 1.3v, VRM 8.2 supports voltages only as low as 1.80v. The Upgradeware adapter is cheaper, simpler, and more reliable than the Powerleap IP3/T, because it uses the motherboard’s VRM. Since VRM 8.2 boards can’t detect a CPU at anything lower than 1.80v, the Upgradeware adapter should only be used on VRM 8.4 boards. Conversely, the Powerleap IP3/T adapter is compatible with both VRM 8.2 and 8.4 motherboards, but it’s a waste of money and a sacrifice in reliability to put this adapter on one that already meets VRM 8.4 specification. If your board was designed or revised for use with Coppermine CPU’s, it should work wit
