AMD FX OC'ers Club

Ok I think I found my limits, I think it may be thermal. at 4.7GHz I run mine at 1.381250Vcore for it to be stable in OCCT. At 4.8GHz OCCT errors out at less than 1.418750Vcore. At 1.418750Vcore OCCT hits 85+ C and stops. I presume my CPU cooler is limiting the overclock beyond 4.7GHz? I have my system specs. Do I need to go water cooling or change the fans to higher pressure models? What about Case fans too or does that matter?

I also noticed when I raise my case fan speeds for both intake and exhaust the CPU fans start jumping in RPMs. I have 2 Intake and 2 Exhaust, 230 and 140. for the CPU its 140 from Scythe

You're definitely limited by your cooling, and 85C is a REALLY high temp for these chips. IIRC, I was told to keep it under 55.
That said, impressive clock on air!

Yes definitely the end of your air cooling and 4.7 is nothing to sneeze at. As for additional cooling it's up to you to decide if the extra 2-300 MHz is worth the investment. I run my HTPC/daily FX-9370 at 4.7 and I haven't found any games that it can't play. Most games these days if you have a good GFX card you won't see too many issues.

Hi there.
Long time since my last visit.

Last night I tried a little more OC to my pc.

4.2GHz at 1.4125v ran prime95 1 hour without errors
4.3GHz at 1.4125v unstable system freezes
4.3GHz at 1.4250v ran prime 95 1 hour without errors
4.5GHz at 1.4250v unstable system freezes

Here are some cinebench scores.

The problem is I've noticed that Load Line Calibration does not work proerly.

LLC possible vaules are: Auto, 1/2, 1/4 and Disable. 1/2 for AM3+ and 1/4 for AM3.

I've bought this mobo (Asrock 970 extreme 4) long time ago with 1.1 bios version and upgraded bios to support fx-6300.

With 2.2 bios version.
LLC set to 1/2 and Vcore set 1.35v, voltage readings (cpu-z, aida64, hwinfo64) are low in both idle and load, but when LLC is set to disable vcore readings are better.

So I decided try newer bios version 2.6, it is messy too.

For exemaple: changing multiplier, vcore and LLC.

4.0 GHz, 1.3500v, LLC set to 1/2. The readings are 1.37-1.38v idle and 1.32-1.33v at load.
4.0 GHz, 1.3500v, LLC set to disable. The readings are 1.44-1.46v idle and 1.41-1.49v at load.

4.3 GHz, 1.4250v, LLC set to 1/2. The readings are 1.44-1.45v idel and 1.39-1.41v at load.

4.2 GHz, 1.4125v, LLC set to 1/2. The readings are 1.43-1.44v idle and 1.37-1.38v at load.
4.2 GHz, 1.4125v, LLC set to 1/4. The readings are 1.44-1.48v idle and 1.43-1.48v at load.
4.2 GHz, 1.4125v, LLC set to auto. The readings are 1.44-1.48v idle and 1.43-1.48v at load.
4.2 GHz, 1.4125v, LLC set to disable. The readings are 1.44-1.48v idle and 1.43-1.48v at load.

Last night I downgraded to 2.5 bios version but it works in the same way that 2.6 version.

Any advice or sugestions are welcome.
Thanks in advance.-

PD: I dont know if other settings in bios affect what I'm doing, so settings in bios are:

Overclock mode ....................=Manual
CPU Frequency (MHz)................=200
CPU Dynamic OC.....................=Disable
PCIE Frequency (MHz)...............=100

CPU Load Line Calibration..........=1/2 (For AM3+ CPU select 1/2)
DRAM Voltage ..............[Manual]=1.50v
NB Voltage ..................[Auto]=1.145v
HT Voltage ..................[Auto]=1.200v
CPU VDDA Voltage ............[Auto]=2.56v

CPU Thermal Throttle...............=Auto

I used to have the 970 Extreme 3 which I has the same 4+2 power phase as the 4. I also got the FX-6300 and I couldn't get past 4.3ghz without one of the cpu core throttling at 1.4ghz during stress test. I come to believe after days of tweaking, even placing a high rpm fan at the vrm area that they are insufficient so I ditched the board, bought a CHV and I could get 4.7ghz without a sweat. 4.9ghz with further tweaking though the Corsair H100i that I've been using started to reach its peak performance during stress test that is.

Eventually no matter what you do the OC won't go past a certain point. That said, impressive OC on air cooling, but those temps are insane. I would reduce the clock and vCore a bit to get the temps down. This won't impact performance all that much. Hopefully the newer upcoming ZEN CPU design changes that, and every little OC will make a huge performance gain.

I hope for AMD's sake it's a rabbit in the hat and not a turkey this time.

85 is absolute maximum temp for the chip, just volts make it reach that in OCCT, under normal load my chip sits in the 40s-50s

the Vcore for 4.7Ghz to pass OCCT is needed though.

yeah a 290 Vapor-X (too bulky) will run for sometime.

Hopefully they will have 1 last chip for AM3+ as of Zen...

as of Today I pushed the CPU up to 5.0GHz, Vcore for stability so far is 1.406250.

 

[Dieinafire]

Any chance we can rename this club the firemans club?

 

[cdawall]

What happened to everyone in here?

 

[VulkanBros]

They have left AMD.....
Well I'll stay

 

[TheoneandonlyMrK]

been a long time out now the FX Brand and this thread has a few points covered already so,nothing new to say i suppose.

 

[JrRacinFan]

I'm still alive n kicking @cdawall

 

[cdawall]

I have been out of the business for a while looks like really nothing has changed with AMD lol.

Only thing I see of interest is newer Intel sh*t.

 

[cdawall]

Hopefully that will change again with Zen. We will see, only time will tell. Hell my 9370 still chugs along fine in anything there really hasn't been a reason to upgrade.

 

[dorsetknob]

Only thing I see of interest is newer Intel sh*t.

And That is all you will See untill AMD release the Next new CPU

Rumor has it that its Slated for a Paper Release on 1st April 2016

 

[suraswami]

PC as such is no more exciting until this GPU re-branding nonsense ends and new CPUs with real innovation shows up.

Moved on to Photography

Unless that's an April Fools ...

I've been away for a while just ghosting and seriously. I feel as tho nothin changed, just a few better graphics cards....

@suraswami

With you on that. Been doing some android dev while away.

 

[dorsetknob]

Unless that's an April Fools ...

would little old me do that to you

Of course its True you read about it on the internet

Our source didn’t go into much detail about Zen, but from what we learned Zen will be AMD’s focus for the duration of 2016.

AMD announces Zen in 2016 (intel is scared)

See no pullie leggie or plonker

 

[Athlonite]

Yup still here and accounted for and very interested in what Zen is going to bring

I'm pretty sure Zen is the reason we are seeing hints that Intel will have more cores on mainstream chips in 2016 (Cannondale?).

I'm actually looking forward to putting a new box together in maybe a smaller case with Zen/Arctic Islands or whatever looks good this time next year.

In the meantime, I don't think I would see any massive benefit from upgrading to the current stuff.

 

[cdawall]

AMD releases graphs like that all the time they have been proven to be a crock of shit every time.

Regardless, I'm still excited to see if Zen can pull AMD's asses out of the fire.

I hope they do, but I also know regardless intel will cheat, lie and steal to hide any AMD improvements.

 

[Johan45]

Just a waiting game at this point, still a year to go.

 

[YautjaLord]

I'm still here. My 4.8GHz OC failed, so now i'm on stock frequency/cooling/etc..., but i got 2nd GTX 760. Waiting for "Zen", in a meantime kicking the sh*t out of everything & everyone in Carma:R, SP (called Career in game) & MP; Car Crusher mode is favorite MP mode, Classic Carma - fav SP/Freeplay mode. Game runs awesome on stock 8350 clocks too, SP & MP.

'ssup everyone, long time no see.
