AMD FX Overclocking

Today I tried some tests, but everything is changing after 5 GHz, one module is bad and high voltage cant much help to stabilize 5100 MHz Cinebench run. So around 5100 MHz is the limit for benchmarks.
At second glance, OC froms tock to the 4.9 GHz stable is still very good :)

They're not anything special, just like the fx9590 isn't anything special.My fx8320 from jan 2014 had the same voltage/freq scaling and clock room as seen by Flank3r.+ It's all luck of the silicon and having a very good cooler, in Flnk3r's example he isn't using it inside a case either.
 
I have managed to get 100% stable @ 4.6ghz @ stock voltages which is good. No temperature increases either via stress tests/games on socket or core. :)

Will leave it like that for a while as a 24/7 setting but it looks like I will have a lot of headroom for pushing further.

Great news Gamble!

To be honest unless your benching I found going above 4.5Ghz was wasted as it only produced more heat and with that instability chance for the 8320 of mine.

I can push it to 5Ghz but it is not stable, I think one core is the culprit and not worth the excessive voltage. 4.5Ghz plays most games just fine so I have mine around this frequency too. :)

hehe should be meldarth or meldarthx :D I've been throwing up a lot of videos with VSR on twitter lately.

Doh will check first link after I get home from work :D I got to do a little clean p and hopefully get some rig pics soon :D

Added you, i think. :p

EDIT

Got myself a new FX8370E and an A10-7850K to play around with.

Has anyone tried clocking the APU's, do they clock like the FX chips? :)

Of course, I did OC of Kaveri chips :)...The limit with good air cooling is around 4400 MHz for CPU. APUNB around 1900-2100 MHz and iGPU 950-1050 MHz.

voltage:
for CPU around 1.45-1.47V
APUNB(iGPU also): 1.35V-1.4V

The chip with voltage at both side is very hot. Ussually CPU scaling very well around 4300 MHz and 1.4V and iGPU 900 MHz with 1.25V. Some as sweetpoint :)

This one was better than average, now I have one and it is worse ´-100MHz







But A10-7870K are clocking better. I have not some in my hand :-(, but Stilt wrote these chips are +200-300 MHz better for OC. I think, its new stepping of Kaveri.
 
I got to disagree on the E chips Davidree; my 8320E hit 5 Ghz with just chaning the mulitplier and going to 1.45v....with ave 1.4 volts; once I started playing with northbridge and fsb I got 5.055 Ghz at 1.46 volts......


I could go higher but I think one of the modules is crappying now; most 8350s don't do 5Ghz easily or a lot higher volts; 9000 series can but not usually that low of volts.

I think the E chips are another stepping; or they've improved the process that much. I could back her back down to something like 4.8 and most likely be 1.35v or less but I kinda like having 5 ghz machine :D
 
Well the 8350 is in. sitting at 20C at stock with all the thermal controls turned off but have to go away for the weekend before I can fiddle with it :(

best stress test is realbench is that the consensus?

Hello fella,
I've already mentioned this in numerous threads including this one.

In late 2013 they refined the fx silicon for less leakage, this led to the marketing of the 9370 and 9590. From this silicon they also reduced the base clock and full turbo, by using 6 refined pstates and marketed these as e editions. If buying an E edition you are guaranteed a newer cpu. Some people think the e editions have more room for overclocking, my opinion is that they do in comparison to most 2012 fx's, but more so they require less voltage to hold 4.5-4.7 ghz. 2 fx8320's I purchased in dec 2013 also overclocked with similar scaling to the e editions, but in stock form had excessive vids and were binned way below their actual potential.

It's a game of chances but i'd say get the cheapest fx8 over a 9370,9590.

as for clocking kaveri on gf28 shp, you will hit a brick wall at roughly 4.3-4.4ghz

Don't take offence but, I must correct people who refer to the ht reference as fsb,

Yeah, Don't use Prime95, it doesn't actually stress the CPU, not properly, it just boils it.

Cheers humbug.

The 8370 is passing a run at 4.7ghz. multi @ 22x, FSB @ 213, HT @ 2500


with a V at 1.380. Cant really go higher due to temps but seems like a reasonable place to stop

Dude as I said I disagree and show me where I said fsb was HT?? I didn't meantion HT as I was at work and didn't remember the numbers off the top of my head ;)
