PCs tested with the TimeHarp260

This is an old revision of the document!

~~TOC~~

We have unfortunately encountered compatibility problems of the TimeHarp 260 with a few desktop PCs. The problems are mostly found with the low-end PCs of large manufacturers like DELL and are caused by a wrong implementation of the Active State Power Management (ASPM) in the BIOS of these PCs. For all non-listed motherboards/computers a general rule is that TimeHarp should not be connected directly to the processor. You should search for a PCIe slots that are connected via the chipset (mostly all PCIe x1 or PCIe x4 Slots). The motherboard manual should contain info regarding whether a particular slot is connected directly or via chipset to the processor.
