- Flashing from bios F2 to F6a with @Bios works ok, but will revert to F2 quite fast if you have trouble with oc settings/booting.
- Flashing from F2 to F6A with @Bios, you can then use normal bios flashing from Quick flash on boot. It might still revert to F2, but less frekvent.
My three 2600K are quite different:
L040B690: max 45 mp without "internal PLL", max 50 with it. Runs 4.8 on air with quite good temps. Memory oc not tested.
#1 L040B165: max 48 mp without "internal PLL", max 54 with it. Runs 4.9-5.0 on air with good temps on air. Memory is strange, at or below 4.8 I can use up to 1866 np, above that it struggels.
#2 L040B165: max 50 mp without "internal PLL", max 54 with it (hopefully more with better cooling). Can also do 4.9-5.0 on air, but with higher temps than #1 (+8 - +10c). Memory oc is good, 2133 np.
Gone do some more testing regarding memory oc, hopefully I can figure out why #1 doesnt like increasing QPI/PLL voltage or oc memory above 4.8.
SB really turns out to be a hunt for the golden cpu's with high mp, not much skill required yet.
