AMD FX-3600 - Problem Question - Fluctuations on defaults

Davedree · 30 Nov 2014 at 02:43

With llc on you are over working the vrms and phases harder, so they will heat up quicker, With it disabled you reduce the workload on them but suffer v-droop but it's not a problem unless you want to push big clocks.

Yeah problem is you're still hitting 1.28v, we need it down to 1.20v ideally then i reacon there won't be any throttling, then on the other hand another board could get you to 4.4ghz or more.

OOCT reporting errors with current settings now! If I'm aiming for a lower voltage does that mean I'll have to underclock my cpu to get it stable and not fluctuating in speed?

Also, just re-did test 5 without errors and gettings big drops like before, damn this motherboard! Will try a fan now if I can squeeze it in.

Re-done test 5:

just looking actually you might be holding 1.2v but peaking at 1.28v

Davedree · 30 Nov 2014 at 02:52

yeah your hanging is not enough juice for the cpu, and we're already 300 mhz down from 3.8ghz so don't want to go lower than 3.5ghz

I reacon get the voltage upto 1.225-1.3v and try gaming or the things you do normally.
prime 95 occt and test programs put an unrealistic load onto the cpu, where most apps and games don't push it so hard

Well, 3.5 is the stock speed, I'll monitor in games etc though and see how it goes. (have re-done test 5 and posted in prev post btw)

Planning on upgrading within the next year or so, you can be sure my next motherboard will at a minimum have decent VRAM cooling ^.^ thanks for your help Davedree

3.5 is base clock, but stock is 4.1ghz to 3.8ghz in turbo mode.

Good luck fella

On a Gigabyte board it's called APM (Active Power Management) Disabling it stops the throttling. Not all boards give the option to disable it though.

And when you disable it not all board really disable it.

Just wanted to add, today I extracted some big heat sinks from old motherboards and stuck them over the VRM's with a fan, no difference at all.

Conclusion, cheap board = cheap performance!

My gigabyte does. It did throttle it once with APM disabled during a stress test but I realised it was protecting itself from dying as once I stuck a fan over the MOSFAT heatsink it never throttled again. But without it off it throttles like a bitch on stress tests. Now with the fan I can run stress tests for hours and it stays bang on 4.5GHz.
