First time OC, new to PC building and OCing. I want to hit 4.0 on air in a few days when my parts arrive. I will be checking back, help appreciated.
I currently had an OC stable at 3.6Ghz, however I lowered the VTT from 1.17V back to stock 1.10V. CPU-Z records 1.248 idle for Core Voltage however (not sure if thats same volt or turbo increasing it). I have not retested this because I am afraid of temps and dont want to fry my mobo or cpu 1 day before my HS arrives...
My CPU idle temps have dropped to 52-54C compared to 63-65C at 1.17V with stock cooler.
Following this guide
I am told that 100C during IBT (I think it says it on page 3) on max is fine. I did a 3x pass on max with 97C temps on a few cores with some @ high 80's and it passed. My friend also said 85C is fine although I dont know how much he knows. I am currently using stock settings including turbo, 22x multi, 164BCLK.
I have also been playing BFBC2 for several hours at 80-85C for several hours with no problems at the 1.17V mid 60's C idle.
I bought a Scythe Mugen Rev.B, Arctic Silver 5, 4x 110CFM fans, and plan on doing my monthly dusting and do cable management (compared to cable terrible insanity) when everything arrives in a day.
I have 60-70F room temps along with 43C(60C load) OC'd 9800GTX+ 1GB 775/1945/1050 65% fan and 54C CPU full fan. I haven't tested stability at the 1.10 stock volt for CPU due to the fear of explosions.
I am using this forum along with the previous guide and
which uses my mobo and cpu
Im very tired atm, very new to OC and this is my first build. I think I understand most of the things I need except temps and ram timings.
Again any help or tips is appreciated, my sig has full system info along with what I listed here. I also have a Msi GTX 470 Fermi Twin Frozr coming. Im sorry if any of this info is excessive but I'd like to be thorough if anyone answers while I am sleeping.
85C is what mines running right now, but thats with an aftermarket cooler overclocked to 4.2Ghz.. quite a huge jump there.
Perfectly safe temps are from 50-65 under full load. But don't sweat it if you hit 70C. Running with high temps tends to lower the chips life. Just all the excess heat and stuff.
Ram timings are kinda hard to understand to begin with. So don't worry about that either. They don't affect performance that much unless your up in the 10's 8's or 9's are fine.
I would recommend trying 21 X 180 with a vCore of around 1.2 or something. run IBT for a few runs, if it fails then bump the vCore a little bit until it passes IBT on max, then run Prime 95 for a while. Overnight if nothing else.
EDIT: VTT and vCore are two different voltages. When your in CPU Z core voltage = vCore
I don't think it shows VTT in CPUZ
