Striker Extreme + Q6600 going at 1333FSB ~ 3GHz (between 58-62°C on full load) - added another fan to Zallman copper heat-sink
took me 2days to get it to be stable!
BIOS 1301!
none of the others worked for me, no matter what voltages i tried with 1333FSB
(had a problem degrading to 1301, i've been on 1801, but it is good only for 45nm proces and doesn't do anything on Q6600, but make it less overclockable.)
when i forced the awdflash to flash back to 1305 (before i knew 1301 was better), i destroyed my BIOS and luckily Striker has a failsafe bootup POST flash, so i could use the ORIG CD of MOBO to restore my BIOS back to the version that was on CD (0906) so flashing then to 1301 was simple, because it was an updated firware compared to 0906. (i always use EZFlash)
put VCORE +.1 ~ 1.35
memory ~ 1.85 (lowered from 2.1, cause i don't need - most striker BIOSes usually just cap it at 2.14V)
VHT +.1 ~ 1.3
NB +.1 ~ 1.3
SB +.1 ~ 1.6
VTT +.1 ~ 1.3
as u see i've raised all the voltages a bit (+.1) NB especially, because i have all 4 DIMMs full.. 2x2GB Geil 5-5-5-18 + 2x2GB Corsair 4-4-4-12 on 2.1V, but im using them UNLIKED on 800 / 5-5-5-18 with memory on 1.85V (over/undervoltage) to cool it a bit, because with 5-5-5-18 u can use 1.8V (the lower specified by the DDRII).
what i recomend is that u try raising these voltages with your proc on def (1066FSB*9) and then always check it out in BIOS
under hardware monitor/voltages, to see if they have rissen accordinglly and if they are somewhat stable (they don't jump up/down for more than let's say .05V).
BTW... disable all spread spectrums and special abilities (SpeedStep and such) i've left only the execute disable bit
If everything OK, try raising FSB to 1200 (2.70GHz) if stable go forth and try 1266 and then finally 1333.. check temperatures regularry and do all this in BIOS, just to see if there are any anomalies.. because u see, u can spot an unstable system early in BIOS if u know what to look for.. and voltage ups/downs are definitely one of the things to be aware of.
If this works, Windows is your next stop and CPUZ, to check if memory is DUAL, ratio mem/fsb and if FSB is ok.
CoreTemp to follow the temps. of cores.. G0 goes to MAX 72°C
PCProbeII for monitoring the voltages and simple temperatures in your box.
(using PCProbeII i've seen some Voltage instabilities when trying to get a stable rig and it always crashed if there was one Warning about the voltages going of charts - it happened when the setup wasn't ok - I remember VHT going crazy for a tenth of a sec or so when it was on DEF 1.2V - too low i guess.. fixed it by raising it to 1.3V which is normal considering the BUS speed now.. from 266-333)
That's about what i've done to make it work.. hope it helps.
regards.
