fx-8320 overclock

[Guest]

Did I win the silicon lottery? 

 

I am pushing the chip to 4.8 gHz on 1.4116 V with 1.26 NB V.

 

Anybody with personally experience with overclocking this chip? I would like to know if putting more into it would be worth it? I could easily raise the voltage to something like 1.45v comfortably and get to 4.9 or even 5.0 gHZ.

 

I am running at about 45 degrees on load with a cryorig h7.

Sorry for the language but seems like you got a real good chip.

Most of the time, you need like 1.45V to get at least 4.7GHZ.

Even with temps of 45C load at 4.8GHZ, you got a good chip.

Better than mine as it likes 1.28V at 4GHZ when it's summer time and 1.32V at 4GHZ when it's winter time.

they are safe to about 1.45 - 1.5 v. go ahead to 5.0GHz and have a fx 9590

do amd chips do voltage differently then Intel? Intel is 1.35V and your saying 1.5V for amd

yeah, they handle voltage differently

1.5 is the absolute max without ln2

with ln2 they have hit 1.7 - 2

haha, well thanks for the feedback. damn, that's unfortunate that you can't push yours a bit further. 

 

I am sure someone with a bit more knowledge could set some records with this thing. I feel compelled to live up to the responsibility.

yeah, that would be awesome, but I'm on a 970 board which makes me think that it might limit me before the chip does. I am going to test a bit more voltage, but from what it looks like it's not responding well to 1.456 V.

it seems like they do differ, the AMD's require/demand more V for overclocking.

yeah, get a 990FX for 5.0GHZ please. id stay with 4.8 though

this would be perfect ^

WIth a 970 board...i think @Morgan MLGman is the only user on the forum who has gotten to 4.5GHZ with a 970 board.

You have to be careful with a 970 board, it's VRMs aren't the same as the 990FX boards.

But since i'm using stock cooler, i'm not really overclocking that much atm.

I can get to 4,7ghz stable with no issues but I decided it's not worth risking damaging the VRMs since it's a 970 board for 200mhz difference so I kept it 4,5ghz @1,36V as a 24/7 use

I'm considering grabbing a used 990FX Sabertooth and overclock to 4,7/4,8 until Zen comes out and depending if it's good, decide whether to get Zen or Intel's equivalent cause I don't see any reason to upgrade now, the CPU is capable of anything I throw at it

Considering this was a budget build, and the future growth of this pair (Mobo + socket/cpu), or lack there of, I am not trying to spend more money just to overclock into the heavens.

Now what would say is a safe temperature?

 

I am seeing sub 60c on TMPIN1 on HWMonitor, and 30-32c for TMPIN0 and 2. I am not sure what exactly those correspond too, but I am guessing they are socket, and VRM temps, respectively?

65C - 70C is okay for amd

awesome, from what I am reading I am seeing more or less the same, with your information on the prudent side.

 

So, either way, I feel like this is a safe overclock to run. I think the low voltage helps and I can try reducing the NB voltage to see if I can maintain stability with less heat going through there.

Use Speccy to monitor temps, don't go near 70 degrees (remember to stress test both GPU and CPU when using an aircooler cause the heat from the GPU goes onto the aircooler resulting in increased temperatures during gaming than during stressing the CPU only). If with your GPU and CPU @100% you're getting around 65-67c then you're good. Use AIDA64 for stresstesting.

Holy crap. Mine goes to 4.7 with like 1.56V and 1.56 on NB at like 70ish degrees under load with a raijintek triton

So I've been toying around with this more and I at least want to update the thread so someone doesn't stumble upon this, as the information is not complete.

 

I stressed tested and wasn't finding stability with the aforementioned settings. It would run hard for about 30 minutes and then crash. 

 

So I have added .05V to an effective 1.464V. The northbridge voltage remained unchanged. I am almost 100% that it will run 4.8 gHz all day with these settings. All other temperatures are more or less the same. 

 

I was surprised at the delta needed to go from nearly stable to completely stable. I will be testing the bottom end more thoroughly as time moves forward, in an attempt to find lower stable voltage.
