yep,for 200 bclk most i3 i have had need 1.32v to 1.38v vtt.
my good one neede 1.32v up to 210bclk and my worst one
needed 1.38v to 1.40v for 200bclk running ram at 1600 6-6-6-19
and my UD2H's with all my cpu's would work with these settings
i used when ever i got a new chip to start my basic testing
20x200@4000 DDR3-1600 cl8
vcore - 1.34v
vtt - 1.34v
vdimm - 1.60v(whatever your ram needs)
then if it primes for and 1 1/2 then drop vcore
until it fails(low vcore normally reboots) then set
it one or two notches above the vcore it failed at.
then do the same with vtt,run prime blend until
it fails(normally in prime it will freeze with too low vtt)
Thank you very much for your help, It seems Im getting my system more stable, let me tell you, it only worked until I set PLL as enabled, with PLL disabled I climbed both vcore and vtt up until 1.4v trying all combinations and all I got was BSOD.
Now im using your settings with PLL Enabled and 8-8-8-24 1600mhz ram @ 1.4v.
Ii even got me more GFLOPS in Linx loops (5 loops so far and seems pretty stable) 29.+something, with each value very close to the other. Thank you, of course now I'm fine tunning your settings.
