No worries there mate.The size of the L2 cache does not determine MoBo selection so much as the socket itself and the supporting chipset.I once ran a 3500+single core cpu with a 1mb L2 cache.I then repleaced it with a X2 4400+dual core cpu with 2x1mb of L2 cache.So ya dude,go for broke.Goodluck.

As what I have understood your mainboard must support PCG = 05A
Â«Platform Compatibility GuideÂ» label there is the marking Â«05Ð?Â» which is just the factor of platform support. In the motherboard's specification, this factor is normally shown in the "Supported processors"
Intel is really crazy not posting differences between the 2 if Intel 925X supports it. I usually check asus.com for similar chipset and processor support.
Better check with HP, maybe they have bios update on your workstation to support the processor
