the VTT charts available are based on actual measurements of VTT voltage on board, it seems that 2/3 is always a bit lower than 0/1. Thats why you see values like
96 (0/3)
95 (1/2)

AS FAR AS I UNDERSTAND now and with the help what praz said:

I look at my VTT voltage in bios (what bios says, not what i SET it...) , then i set 0/3 and 1/2 69% of VTT and NB Ref GTL at 68% of VTT. I think this is how its done.

---> But i STILL didnt get an answer what would be a reasonable, max CPU VTT voltage! <--------- !!

Btw. my 6600 CPU totally sucks, i dont understand it. How can it be prime stable at 3537 - but if i add only 15mhz i immediately BSOD !!

I need to know what causes the BSODS...and why OCCT not only gives me a "crash" (calculation error) but always those BSODs, sometimes 2 seconds after i start OCCT. 15mhz less and i can run prime stable!!

Also, in regards to straps in bios: 266/... 333/... and 400/...

I did some testing and noticed that the 400/... strap gives me higher latencies, also if i run ram FASTER than with 266 strap. Same timings and ram even slower under 266/... everest shows me better benchmarks and lower latencies! Like 57 compared to 65ns udner 400 strap.

I chose 400 strap and set ram fast and SAME timings and get very bad latencies.

Well a good q6600 depends on the batch, whats your batch and VID?

L741, Vid right now (as set in bios) 1.40something - 1.41. Dont want to go higher

my problem is not instability, but rather BSODS if i go higher. playing with GTL ref right now and VTT.
