Here's a strange problem. I generally run BurnInTest 4 or 5 Pro on a machine with CPU MMX/SSE, CPU maths, RAM (torture mode), 2D and 3D video all
at 100%. This loads the machine heavily, and I find, gives the best overall stress test. Normally on a 2000+ MHZ machine with a good video card (FX5200 or better) the 3D video runs at 20 to 40fps. On the machine I'm currently testing (an AMD X2 3800+ with an ATI X1800) I'm getting 2.5fps with the same test (the laptop beside it, which Intel graphics, is getting 15 fps.) The 3D test runs fast when I run drop the CPU tests, which suggests to me that something is bottlenecking the PCIe slot when the CPU is under full load. Is this a known problem (either with BurnInTest or Windows) and is there a fix?
