I knwo other had problems so I was worried, but this MB and memory combo seems to work fine for me so far. (p4t533c / kingston 1066 ecc / p4 2.26)
I set it up in "jumper" mode and set to 17x and 133 etc. On boot gave MEMORY error and would not boot up.
I set to JUMPERLESS, and it boots up 100% ok.
Memory is at 4x.
Anyone else have that issue? I double checked my jumper settings and they were all correct.
Weird, but I guess I don't really need the phycical jumper setup to work.
