AMD FX Overclocking

APM master has the eefect, the TDP of chip is still around 125W (For 125W chip). So example you did OC to 5 GHz with APM master enabled and in Superpi 1M your score will be around 16s, so the same as with APM Master disabled.
But you can run Cinebench R11 or R15 and all threads will be jumping up and down because APM Master ant keep your TDP around 125W and score will be low. Example around 7.7 points. With disabled APM Master it will be correct and it is around 8.6 points at 5 GHz OC.

nice good to know :D

sep mines rated for 95w :D I'll get some more screens of mine up and running tonight *hopefully* she's ave 1.464 volts at 5ghz....figured that's safe range....once I start pushing her higher volts start ramping up and then heat.

I think I might be able to get her to boot at 5.3Ghz; don't know if I could get 5.5 lol......but she's a little champ for the price; she's outclocking a lot out there..
 
Wonder if you could help....





Everytime I go to do a stabitity test in AMD overdrive, The Core voltage drops down to about 1.42 and lock's the the p.c

Have set the vcore to 1.5 in bios...

any reason why it would do this....

Didn't have a chance to test this last night as my internet was down in my whole postcode till about 4am this morning.

Fingers crossed it works :) this was literally the only issue I had, temps fine etc

Well it worked most of the time with a few glitches so today I decided to restart the process.

Reset CMOS, bios back to scratch and instead of using level up I did it manually.

So far, I have only went to 4.4ghz on stock voltage and all is well. Did a quick blast on prime for 15 minutes but will resume for longer after dinner and do it properly for 45 mins/1 hour or something like that.

If all goes well with that, I will see what I can get out of the stock voltage first and then decide if I want to push farther than that. :)
 
MIT/ADVANCED VOLTAGE SETTINGS/vcore load line calibration, this is setting what help you with lower drops or overvolts.
But depends at quality of VRM circuit of the board.

But Im afraid, the UD3 is not able get better LLC settings without drops. Asus has much better this behavior example as Sabertooth 990FX R2 or Crosshairs V boards. So one things what you can do is higher voltage (example 1.55V in BIOS), thats mean, in hard load your real voltage drops to example 1.44V or so and it could be OK. For light work or idle is 1.55V OK. You can still try all combinations of vcore LLC (auto, 50%, 75%, 100%) and how react it with "real" voltage in load CPU-Z

Heheh commmented Flank3r :) I'm running sabertooth board.....and very impressed by it :)

Ok some more pics folks

Cinebench could be light better, if you close all programs at backround, score could be around 790 points, right?

For superpi is good BD x86 fix (some boards have this fix in BIOS, some boards not)

Flank3r yea I thought I could get some better scores on stuff if I wasn't running some things in the background :)

what's safest voltage you'd say to run through it for everday use? I'm a bit worried about going up to 1.5+ volts....pretty sure I shouldn't be LOL.....but just am; damn not had this much fun OCing in a long time
 
Doesnt the top fx chip run at 1.5 as standard? im sure i heard that on a video some time, but im guessing theyve strapped loads more caps on it.

could be right :D guess just coming from old school overclocking; trying to keep the volts as low as possible. but seriously impressed with just this little chip. I'll most likely try as push it tonight to see what I can get :)
 
All depends at temps of chips and leakage.
Example some FX-8350 can VID around 1.27V and some 1.35V. Safe voltage is behind 1.45 to 1.55V depends at temperatures inside the chip.
I had one FX-6300 and with 1.45V was this chip very hot and hit 4950 MHz stable. But another one no problem with 1.55V.

I think, AMD said with Bulldozer launch in 2011 the daily voltage is ok 1.5 V.

ah, I thought its global AMD page, there Im some years :)

My best OC results, hope some day get more (think 8240 or so is possible)

Thanks dude, i sent you an email. :)
 
I got some more for you guys :) Matt you might of seen some of my tweets last couple days on Big Red Machine 2.0 :D

I couldn't get her over 5.26Ghz......at least get her to boot....I'll have to play around but I seriously can't believe how much 8320E is a beast......from 3.2Ghz base to 5 Ghz......without really breaking a sweat; even 5.1 Ghz isn't that hard......anything over most likely hitting voltage or heat limitation.....
