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

think i'll leave it all to auto and see if the board can do it.. even if its brute force overvolting everything. if successful i can fine tune it from there

edit: anyone else used auto overclocking / know if its any good?

Yep it seems counter to what the bios tooltip suggests too. It is a strange one and may be particular to some systems. Some always recommend leaving it off, some find stability increases with it on. All I can say is that with it on, I am able to get to around 5.25 GHz. With it off I seem to be reaching a ceiling of around 5.1 GHz. I use a combination of multi and FSB. There was a debate about it on overclock.net a while ago.

I'd only recommend enabling it if you have reached a ceiling with your OC to see if it makes a difference. If not, disable again.

Just saw this, sorry for yet another post. I have only ever used auto-OC on my Rampage IV Formula on the 3930k initially when I was learning the ropes with the bios. To my horror it applied close to 1.5Vcore to the chip just to reach 4.2GHz!

Much better to adjust really important parameters (like Vcore) manually. To put it in perspective, my 24/7 OC at 4.5 GHz on the 3930k is at 1.32V!
 
oh i know most auto clocks are rubbish for voltage.. its more just to see if its possible :p

im fine with most platforms to a decent overclock (ivy, haswell,,, AM3).. its those last few mhz i need to find extra skills :D

It basically shoves your CPU full of volts, then puts a crumby clock on it that it knows 100% will work with every single CPU of that model. A failsafe, if you will. It would be a bit funny really if a CHVFZ put an overclock on your CPU automatically that wasn't stable :D

I set the level 2 overclock, then, once I worked out the things it had changed I just went from there. It does all of the fiddly stuff like disables things that could make your OC unstable but are hidden in other menus.

I am currently on 1708 which is 5 months older so I am wondering if the rest of you are on this BIOS or if they are not going to flash for this reason?
 
1708? lol does that even support the 8320 properly? load up CPUZ, does it call your CPU a Zambezi?

The first thing you should do when you get into Windows is check for bios updates dude. My board sucked until I updated it.

Yes it was vishera and was only two updates old spanning 5 months.

Anyway as I was intrigued by the 'improves stability' BIOS I updated it and went back to my last settings however tweaked a few more manual and other OC options.

Interesting to spot that a new option was posed in this version sporting "AMD Turbo Core Tech" seen in the shot below:


Here is the Cinebench result after the update and extra tweaks:

 
Oh and the CPU and PCIe spread spectrum in this BIOS explains in the notes: 'disable for a better chance of overclocking'

Seems like they randomly change bits and cant be ar$ed putting notes into some of the settings.
 
Ran my usual Folding client to test and it gave a Windows Hardware Error Architecture message (WHEA). That's why I think it is a good test to see if the overclock is really stable. Need to think about what else to tweak.

Ah damn not those blasted things. They are a pain. Again a lot of debate about their significance but some (especially if you fold) feel they ought to be eliminated for 100% stability.

I personally never check for them and my guide to stability if the system has no lockups or BSODs in my uses (which doesn't involve folding). A curious thing with WHEA errors is that really often, when the system is not stable or is BSODing while you are refining an overclock, they don't appear. So I personally don't know what to make of them.
 
They are recoverable errors.
Things that can be re processed.
The PC doesn't crash but execution is slowed down by having to do error recovery.
If your seeing WHEA errors your close to the edge stability wise.


A really unstable PC doesn't do error recovery it freezes up or blue screens.
 
Installed win 8.1 so will try to run overclocked cinebench later. I have to say the process of installation was very clunky. Unfortunately I only have Win 8 "upgrade" and it doesn't allow me to do a clean install so it upgrades over win 7 ultimate. So I did that and then downloaded the 8.1 "patch". Computer was at default settings in terms of bios throughout this but it threw several fits when installing 8.1. Display died and I had to clear CMOS as it wouldn't come back on again and normal reset didn't work.

Then when I did finally install it, it kept freezing on the login screen, requiring more resets. Had to start again in the end and now it seems ok.

Edit: Just also noticed Asus brought out bios 1602 2 days ago for the CHVFZ to improve stability on win 8.1
