AMD FX Overclocking

The chief reason Dave is initially this can interfere with testing for stability. I believe it may have been from early BIOS releases but once you are stable you can enable some of the power saving features.

I recall there is one setting that screwed up performance but it hopefully was ironed out by the manufacturers (considering they are archaic three year old dying technology right?).

Cool and quiet doesnt affect stability on k10 or fx, it just enables the cpu to idle at a minimum p-state. You are aware the fx processors have 6 p-states with predetetmined voltages and multipliers.
The rumour of instability dates back to socket.939, 754 when amd cpu's only had 2 p-states and instability could occur,

The ONLY cpu beating the overclocked FX here is the i7's. One of the many comments proving this inaccurate sweeping statement as a factoid.

Thont, Thont, Thont. I think this is the second time I've suggested you get a pair of glasses, or maybe get your cataracts removed.

Literally the first sentence of my post that you quoted:

It's just about the extra performance a I5 would give you in games, compared to an AMD chip.

Oh wait a minute. Maybe you consider Cinebench a game? That would explain it. Have plan playing that dude.

What's even more amusing is that you didn't even find an up to date benchmark to link - can't you see those are all 3-6+ year old Intel CPU's listed there? Don't you understand that Intel have released many new CPU's since IvyBridge?....
Made my point here, backed it up with benchmarks from the latest games, have fun trying to debunk that :) Cya in the next thread Thont, remember your glasses....

Please just get the hell out of this thread already, you've dragged it off-topic too much already. You expressed your opinion and thats fine, however this is the "AMD FX Overclocking" thread. Coming in and basically telling everyone that's bought an FX processor that they're a fool is not a good idea.

Then ask oursrlves why would caq and c1e now not hold back the overclock or cause stability problems with the cpu when enabled after stress testing.

Because those two settings don't affect stability.
Also wholst I appreciate the quick and dirty advice to someone to achieve an overclock,
People should be thorough im their testing and knowledge.
For example relentless have you now exoerimented with offest voltage so your cpu voltage drops to.0.9v at idle rather thsn holding your macimum.
 
I read in multiple places that when you're constantly monitoring voltages and temps you don't want anything interfering, considering you are constantly in the bios whilst attempting to achieve stable overclocks you might as well just turn them off, I cant see how that's not thorough to be honest
 
When stress testing you are looking at frequency in cpu-z, hwmonitor for voltage held and vdroop and temperatures of vrms package and cpu temps.

Using hwmonitor the voltage side you are looking at peak v-core and realtime voltage to establish your vdroop.

Cool.and quiet and c1e are always quoted as needing to be disabled,or incorrectly blamed as reasons for throttling. Cpb and apm are the settings that need tweaking. Cool and quiet and c1e do not interfere with stress testing
 
I turned them off and turned them on again when I was done, as for teaching me suck eggs my 8350 is currently stress/bench/game stable at 4.7GHZ 1.392v with a single fan air cooler, a 290X one of the highest heat generating GPUs available is also installed but the CPU never goes over 55C in games and most of that was achieved by reading this thread although not one of the bashing posts was useful
 
I gave you advice in particular related to gigabytes and that overclock.
I'm not singling you out i'm trying to get people to provide reasons why just because a written document states to disable all power savings, (caq c1e)
When those settings don't cause a problem, if they did interfere like people say they do during stress testing, how do they ?

Also great overclock relentless but you should tweak your v-core by the method of offset voltage, so to get 0.9v at idle.
 
Apologies I'm getting confused with 2 Dave's :o I just found it frustrating when you are trying to read through this thread when you're overclocking which is very time consuming and having to skip though posts

Like I say I just read to turn them off, I didn't bother to read as to why but its completely stable with them on so there is no reason to suggest you are wrong at all

I intend to take it further, I wasn't going to but the itch gets itchier everyday, its addictive :D

I haven't read into offset voltages before, I've not noticed anything in my BIOS that suggests this but I'll have another look
 
Don't apologise I do come across as an arogant ... sometimes, but i'm really only trying to help people. It's just the way I am I like to question things and from my experiences I then question why things are done in a certain way.

My problem is this:
People with little amd overclocking experience come onto the forum and just want the numbers to punch into their bios, they don't care how or what is required they just want 4.5-4.6.4.8ghz etc. When experienced users on this forum give them a quick dirty config setup that's fine, but there's situations where I think hey noo you want to learn how to overclock then do it properly.

If you have the uefi bios on gigabyte, Fail safe way is to reduce your cpu multi down to 18 or so just until you get the voltage right from testing in windows. Remember the voltage you required for your manual overclock.

Then under advanced voltage settings You set v-core to normal, and there is a (dynamic v-core) option. You use the + key or click mouse on it, You work out how much offset to apply over your Vid. So say the vid is 1.3 and you need 1.43v then your dynamic would be 0.130v, but the level of LLC can also affect this.

So with the cpu multi low you can still test the voltage without the cpu locking up because the dynamic voltage might not be enough. Once you're getting the correct voltage then turn up your cpu multi to your max overclock as before and test for vdroop once more, then add or reduce dynamic voltage as required.
 
I can honestly say I didn't even know about that, I'll have a look but sounds like a lot more time stressing and at the moment I just want to play games as spent of my spare time last week tinkering, stressing and benching to get to where it is now

Whats the ultimate goal with doing the above, to have the voltage drop when idling?
 
Yeah idling clocks and voltages for power saving,
Also lengthens the life of your motherboard in particular 4+1 phases boards.

edit offset voltage was a feature on gigabyte back in the 2008-2009 am2+ am3 days.

Why do you amd people always insist on turning off c1e and cool and quiet?
Why manually input voltage when you can use offset voltage overclocking?

From my own experience, disabling these has given me a slight gain in benches, not by a lot though so could be margin of error. For me, I'm not bothered about saving a few pennies on power and aim for max performance, power saving comes later if I can be bothered (Like I said, I'm lazy). disabling them also eliminate them as possible causes of instability (no matter how small a chance they actually will). I will however be trying these settings again now you have said they shouldnt make a difference. I want to see just how much difference they make again, if any. Hopefully I can report back my findings.

As for the offset, I've never tried as setting the volt manually is so easy and predictable once LLC is set correctly, and I should imagine its much easier to explain to newcomers and for them to understand too. Most have never progressed further, myself included (Probably because the system is up, running and stable using manual)
Your guide Davedree will help as you seem to have the skill and knowledge to help people like me to use these underused settings. ;)

Will go up once more on the multi to get it to 4.4.

I'll test it later on BF4.

Cheers. :)

Hmmm. Passed 15 minutes on RealBench.

I then decided to try the new AMD GPU drivers as I have been having problems with them so have stuck on 14.4.

Left PC, came back, black screen, nothing working, rebooted for the BIOS to tell me that the OC had failed.

Taken it down to 4.0 now will see how it goes. Need to put the two new fans on the cooler as well. I suppose I should have run a temp test when the bench was running as well.
