***official amd 83x0 overclocking thread***

From M5A99X bios (I think) for 5GHz

CPU LLC ultrahigh
CPU current 130%
Spread spectrum off
CPU/NB LLC regular or high
CPU/NB current 120%
Power phase control extreme
Dram current 120%
Dram power phase control optimised
CPU 1.5V
Vram 1.65V
CPU/NB 1.25V
VDD/PCIe 1.1V
VDDR 1.23V
NB 1.15V
VDDA 1.269V

everything else auto, try various multis and frequencies, I always synchronise HT and NB freq. Ht should not exceed NB

HT link is not that important really.
I probably meant to have it in SYNC with the NB at 2500 but made a typo in the BIOS.

been tweaking 4.8 some more as this will be my everday overclock im thinking dont want to run it 5 everyday unless u guys think its safe to?

but anyways 8.37 cinebench but putting cpu/nb and ht link to 2500mhz

im sure guys already know this but i added a 40mm fan over mobo vrm and dropped 5 degrees off socket temps maxed out at 62 where as before it was 67 on prime room to add a second may buy one later to see if i gain anymore :D
 
Guys, need some help with my settings, I'm clearly doing something wrong but don't know what. The last two attempts left me with no monitor signal and having to clear the CMOS.

I have a sucessful clock at the moment of a lowly 4ghz at 1.4v. Everything else left at default including power savings options and LLC etc.

The last unsuccessful attempt I raised the multi to give 4.5ghz, raised cpu to 1.45v and switched off C6, C1E, and Cool & quiet. FSB, DRAM, HT & CPU/NB were all left standard and standard volts but no boot/monitor signal.

I realise I'm probably jumping up in stages a bit too quickly, I thought the 8320 would be easier than this tbh, so I'll take things slower from now. How is best to attack this? I need to work out what is giving me the problems?
 
Ok so for 4.8 I have the following

CPU Bus Freq = 240
Cpu Ratio = 20
Turbo = Disabled
PCI Express = 100
CPU Voltage = 1.51875
CPU/NB Volt = 1.265250
Dram Voltage = 1.550
HT Link = 2648
NB = 2400

Ram Timings

11-11-11-27 2T

Speed 1932Mhz

NB Voltage = Auto
VDDA Voltage = 2.55625
NB HT Voltage = Auto
SB Voltage = Auto
NB 1.8v Voltage = Auto

Digi Power Control

CPU LLC = Ultra High
CPU/NB LLC = Extreme
CPU Current Capability = 130%
CPU/NB Current Capability = 130%
CPU Power Phase = Extreme
CPU Voltage Spread Spectrum = off
CPU Power Response = Fast
CPU/NB Power Respose = Fast
CPU Power Thermal Control = 145oC / Extreme
Dram Current Capability = 120%
Dram Phase Control Extreme

All cooled with a Be Quiet Dark Rock Pro 2 which is why I can get away with air.

Click to expand...

Have you disabled turbo? Set PCI frequency to 100. Make sure that your memory frequency is within range.

See settings for LLC in post #221 above. You can play around with the voltages, but at 4.5GHz I would be starting at 1.45V for the vcore, possibly going to 1.5V. To make sure it is not ram, put 1.6-1.65V through it initially, you can always reduce it later

Really though you should be more methodical and go in small steps. Adjust one thing at a time and reboot and test, make notes. Takes ages but it is the most reliable method to overclock a CPU.

CoolBreeze, looks good :)

Thanks guys. Ram is 2 x 4gb viper 3 red ram.

Will be going in slowly from now on.

In my mind, it makes sense to set the power as a high I will need it now, find a stable clock, then look to reduce it, keeping an eye on temps of course. Does that sound sensible?

If so, is 1.5v on the cpu, 1.3v on the cpu nb, and 1.65 on the ram sound good?
 
No need to go so high on the cpu nb unless you plan on running it at 2600 plus, I'd say 1.25 and then wind it up/down if necessary.

1.5 again depends on what clock your trying to reach, 1.5 should be good for 4.7-8 but depends on your chip. 1.65 on the ram is ok but leave this at default timings as it can cause other problems like lock ups and no boots.

Tweak the ram last, so input the rated timings and run it at the rated speed near as you can, then tweak once you have a stable OC on the Cpu.
 
Thanks mate will go with that. Will go with those volts first, check its OK, then enter the options in post 221, check again, and if OK start tweeking one step at a time.
