HT Multi x9 = 2070
CPU-V = 1.45
NB-V = 1.25
If i try to bump up the CPU multiplier so its 4.2ghz and put voltage at 1.5v I cant get it stable, it makes it to desktop but as soon as i run IBT it crashes, is it safe to go above 1.5? I have watercooling so temps arent the issue i havent gotten over 40C so far.
In my experience Thubans like a higher ref clock, with a lower multiplier vs a higher CPU multiplier.
Try either 250 x 17 or 255 x 16.5 and see how you make out. You'll see better numbers for Dram and NB Freqs at this level making a better blend of overall performance!
Stabilize the 250MHz HTT (Ref Clock) isolated from CPU, Memory, NB Freq OC's, maintain these as close to stock as possible till HTT is stabilized with 2 hrs of prime95. At this point start with small increases with only the CPU Freq increased (along with Vcore but only as needed). I'm sure you have a good idea of what you're doing here. Once this is stabilized than work the NB Freq till stabilized and finish with the Ram.
Get things back to where you're currently stable (4.0, 4.1?) but using the 250MHz HTT than go from there.
