Hi Maxrat,
I'm not seeing anything like that. In the bios>Advanced>JumperFree Configuration--I have the following that are all adjustable by "X DRAM Clocks":
DRAM Write Recovery Time
DRAM TRFC
DRAM TWTR
DRAM TRRD
DRAM TRTP
There is no "T" anything. Most of the other stuff deals with "spectrum" or voltages......
I assume its one of the above, but, heck, maybe "JumperFree" isn't were I need to be.....
