Grabbed this pair tonight, was offered a deal i couldn't refuse from a local
Looks like ive found a replacement for the 4000vx
Started off in my usual fashion:
Pulled out 4000vx and chucked in these BH-5's without touching BIOS.
Booted - yay
Set BIOS to 1:1 @ 2-2-6-2-7-12-2-2-1-2 1T etc and MAL 6, RP 5.0
5 loops #5
3.2V - 250MHz
3.3V - 252MHz
3.4V - 256MHz
3.5V - 258MHz
3.6V - 260MHz dodgy results that varied each bootup
swapped sticks in the slots
3.6V - 261MHz dodgy results that varied each bootup
3.7V - 261MHz dodgy results that varied each bootup
3.6V + MAL 7 - 265MHz
obviously MUCH more testing to be done, but i'd say this is a good start:
265MHz @ 2-2-6-2-7-12-2-2-1-2 1T rest all tight and MAL 7, RP 5.0
