im trying to reach 3.6.i got my voltage at 1.5,and i can run prime for 5 minutes till i crash.im scared to go higher with voltage.is there something else holding me back?maybe cpu/nb?my temps are good,so thats not going to be an issue.

flowtek

small fft means its not getting enough vcore, blend mostly about your nb or ram... i say 1.25 - 1.3 for cpu-nb and try to start from 2000 nb, might want to try backing your timming to 5-5-5-18 to see if ram is the problem...

would be nice if you could put your bios settings so others can help

1.5 Volts should be more than enough for 3.6 my 720 BE would do 3.7 on 1.48 volts when I had it.

What are your load temps? Are you running Small FFT or blend? As you may need to give the IMC a little voltage bump.

Also are you using the Multi to overclock or the FSB? -

ive noticed sence i updated my bios,that it seems to take more voltage to get higher ocerclock.does this sound crazy?my ram timings are 5-5-5-18,and i was running prime on blend.can i take my vcore higher?i have a coolermaster n520 on my cpu,does a great job.

flowtek

5 minutes fail on prime blend is still on 1024K fft, i say add more cpu-nb for the IMC just like Riskitall84 wrote.. 1.8 - 1.9 for ram at 800 5-5-5-18, i assume ur using 200x18

happy tweaking

yes,i just flashed back down to 1404 bios to.im going to try 200x18 again.im just using multiplier .and my ram is able to do 4-4-4-12 2.1 v ,but is runnin 5-5-5-18.was hoping to tightin ram up after i get it to 3.6.

getbigtony

what cooler are u using?
what's your temps?

coolermaster n520,never breaks 40c.

Ok so if it never breaks 40 its not temps.

Its either gonna be your ram or your IMC

Find the option in your bios for CPU-NB voltage and give it a little bump

Have you tried an FSB overclock with a lower Multi as my chip did prefered a 15.5 Multi x 239 for 3.7 and 249 for 3.8

see i thought about just going the other way to.i think it would be better to raise everything else ,instead of just cpu.i have a good case and cpu cooler so maybe ill try that route
