my NB Vtt is on auto, so im not sure what it is set to, what voltage do you recommend for this.
and i havnt messed with the pci-e frequency, rasing to 102-103 i can try.
i have read many places that 1.30 is near the most you should set the QPI, have i been reading bad info, or was that just playing safe. do you reccomend me setting it to 1.34 for my next OC try.
turbo, should i try to leave this on and get the extra multi's to push my OC past 3800 or no.
i think no because of stability issues. but you know better than i do, so i will listen to what you have to say on this matter.
and ya i do keep my uncore double of my ram frequency so the problem does not lie there.
pci-e frequency and qui voltage i will try to tweek with to see if i can break the 3.8GHz wall i have atm.
thanks for the help, and thx in advance if you supply more!
OK, this is just a guess purely because I dont know your motherboard, Firstly I dont mean PCI-E frequency, I mean vtt, does the board have Voltage (not bandwidth) adjustment for the pci-e lanes? Mine does and my last did.
You mentioned that your NB vtt is set to auto, does it not give you what the ACTUAL setting is in the BIOS anywhere? Often it will be on the Hardware section that shows fan speeds and general voltages? If not, try downloading a hardware info proggie that will give you all the different actual voltages.
Turbo is purely preference, personally I always attemp to manage a stable overclock first without turbo purely because turbo is just increasing one cores speed in reality according to load only, once you have a stable overclock without it, then try it later for even more speed! Thats just my preference as I said, I dont even really count turbo as an overclock really, again it's just personal because as I said, it's only overclocking (in reality) 25% of your CPU.
On the UNcore divider, I beleive it's at LEAST double, I have read where some have dropped the memory divider but not the Uncore divider and had some better results, personally I havent but it might be worth a try? Say 6 for ram and 16 for uncore.
Lastly, sometimes it's just good to go a bit overboard from the word go with VCore and QPI volts just to factor them out of the equation, you can always drop them down if you get a successful boot. Dont forget CPU Pll also, as your BClock increases, you may need a bit more than "auto" juice there also.
My response is very general with a few things to try purely because I dont know your board and it's BIOS, have you tried Googling the board to find forums with other TPower users and steal their settings to try? I think Xtreme Systems has a TPower overclocking thread for example.
Lastly (really lastly) if you still struggle with the overclock, try the x19 multiplier, on my last board I had much more stable overclocking success with 19x, on this board it's the opposite.
