Hello ! I need some advice.I have a FX 8320 processor and Asus Sabertooth 990FX motherboard R2.0.
My target is 4,2GHz
I use the following settings
CPU LLC - Ultra High
CPU/NB - High
CPU Current Capability - 130%
CPU/NB Current Capability - 130%
CPU Powe Phase Control - Extreme
Cpu Voltage - 1,381
Cpu VDDA Voltage -2.6250
C&N,C1E,SVM,C6,HPC,AMP- Disabled
Multiplier -21
CPU/NB Frequency -2200 default
HT Lin Speed - 2600 default
RAM Profile -DOCP -OC Profile tu run the 1600 MHz (Corsair Vengeance LP 8GB DDR3 1600MHz CL9)
Problem - i run 30 tests in Intel Burn Test and it goes smoothly,in Prime 95 after 3 hours freezes
I have the same setup as you and I can already say some of these settings are too high as in you don't need that much voltage used.
CPU LLC - Low or Medium
CPU/NB - Low or Medium
CPU Current Capability - 100% or auto
CPU/NB Current Capability - 100% or auto
CPU Powe Phase Control - auto
Cpu Voltage - 1,350v's or close to that, if it runs OK with this voltage, go for less voltage used if possible.
Cpu VDDA Voltage -auto
C&N,C1E,SVM,C6,HPC,AMP- Disabled
Multiplier -21
CPU/NB Frequency -2200 default
HT Lin Speed - 2600 default
RAM Profile -DOCP -OC Profile tu run the 1600 MHz (Corsair Vengeance LP 8GB DDR3 1600MHz CL9)
Note that I have changed several settings to "Auto" as a suggestion, the 8320 chip runs hot and FX chips respond well to voltage used. "Auto" settings for no more than the speeds you are wanting should be sufficient in just about any case I can think of in reference what I've indicated as such.
OK - I've ran into this with my 8320 and the biggest problem I had was temps under load - You have 8 cores running under the CPU's lid and these will generate alot of heat. You'd want to run things with as little voltage as possible to help combat this problem. If temps
under load, not idle are going past 55c, better cooling is required before these speeds can be used realistically. Load temps are what's important, idle temps are just that but are sometimes an indicator that a temp problem might exist if you know what to look for.
I can also say these chips have a limit as to how much multiplier they like with standard cooling or really any cooling for that fact.
You could try raising the bus to compensate and that might help things some. Remember that the higher your multiplier is, the
harder your CPU is working to operate at that speed, shifting some of this load onto the NB is helpful. As an example, 19x with a bus speed of 222FSB ='s 4218MHz, so you don't have to drop the CPU multi alot or clock up the bus too much to reach that desired speed. Only real thing is to watch how your RAM acts, all else should be OK since under most circumstances the system should be able to run this way without having to do any real overvolting. I'll also throw in using CPU current capability past 100% will cause temps to go higher since the board will attempt to compensate for loads it runs into BUT since you're not going for extreme OC's it's not really needed here.
BTW lower you HT speed, anything past 2400MHz has a chance to corrupt your HDD, effectively hosing your OS if it ever does. I've never had that to happen before but it's best to play it safe than be sorry, besides you won't get any benefit that can be noted from it being that high anyway.
Watch load temps and see what happens.
I'm basing the above on my experience with my 8320 and Sabertooth 2.0 setup so yours should act closely to how mine does overall.
