This is wrong.
The theoretical maximum of a single PCI-E lane is 640MB/sec, which is above 6.0Gb/sec.
PCIe 2.0 delivers 6 GT/s, but employs an 8b/10b encoding scheme which results in a 20 percent ((10-8)/10) overhead on the raw bit rate, which brings transfer down to about 500MB/s.

640MB/s is not over 6Gb/s, it is exactly 5Gb/s.
Second part is concise explanation of how PCI-E works, how fast and why not as fast as expected.

I can't find the tRRD in the BIOS, is it there at least ?

It's there, where it should be, from the first day - RAS# to RAS# Delay
