AMD FX Overclocking

They are not smashing benchmarks or trading blows with i7, but for £100 I think they are great choices. If you didnt have to pair it with a top-end motherboard to cool the VRM's and use a decent cooler there would be a chasm of price/performance between them and the i5's.

All of them seem to do 4.5Ghz no problem for 24/7 use meaning you dont really need the better binned ones as you can put that money to the GPU.

You are 100% correct. I never bought my 8350 thinking it would be the i7 equivalent but i knew it would do me well.

When I got around to overclocking I have now got 4.5ghz out of my chip with NO temperature increases at all!!!!(doing it manually instead of using the rog level up) Absolutely amazing! I just wonder what I can get until temps start to increase. That us this weekends plan :)

hope enxt week I test my new FX-8320e and 8300 and if time will be friendly, my 4th FX-8350 too :D. Im looking forward, if there will be some great chip :)

I just checked your sig, your totally mad........ in a good way.

I think your probably keeping AMD afloat single-handedly.
 
street I must be missing something; what board do you have? You really should be able to push it higher; have you tried straight multiplier first to get over 5 ghz? that's what I did first and hit it no problem on my sabertooth with my 8320E *seriously amazed by this beast of a chip*

also guys do you want me to run anything test anything......I have most games; etc; will be doing some videos on Witcher 3 as soon as it comes out

Board I have/use Is the GA-990FXA-UD3 (rev. 4.0)...

and been told is not the best by FlanK3r for LLC. it really struggles when I try and push it over 5Ghz.
 
you running the latest bios? also you got anything cooling your vrms on the motherboard? I'd highly recommend sabertooth or Rogue *which just has like one or two differences between it and saber; not sure if its worth 40ish more :D* you got 9590....you should be able to hit 5ghz without issues.....really weird you can't.

unless I seriously got a golden 8320E LOL
 
So I want to overclock my 8320. I'd like to get it to 4.5Ghz, but the higher the better :). All the info seems a little overwhelming and a bit all over the place, so I'd like some help.

To start with, what I'm running.

8320.
Sabertooth 990FX rev1
Corsair HX750W
Alpenföhn K2 cooler.
Kingstone Genesis Grey 1600Mhz.

8320 is at 4Ghz via multiplier, all other settings be stock.

Got a few questions now.

1.5V is safe max for cpu. What about cpu-nb?

Temperature? I assume with amd stuff it's the one marked cpu in hardware monitor and not package? Current cpu temp is 30C while package temps are all the way down at 15-20C, which doesn't seem right and max is 62C?

FSB or multiplier. Multiplier is easier, but fsb has better gains? If I do go fsb, then what do I do with the stuff it changes, just set it to nearest/under?

For example, my memory is set to 1600Mhz. If I bump the fsb to 210, that setting changes to 1680Mhz. So should I change it to the next one down (15XXX or something), same with the cpu-nb and so on.

What to test stablity with, if not prime?


Thanks.
 
^ No such thing as a safe voltage. The higher it is the shorter its lifespan.

You can try overclocking the memory but it's sensible to do one thing at a time. Max FSB (underclock CPU and memory), then max CPU, then max memory.

For now I'd leave the memory, maybe give it a small bump if it's convenient and test with memtest but otherwise underclock is fine.
 
I wouldn't exceed 1.4 volts. That should still get you to 4.5Ghz fairly comfortably.

Your mobo should be able to get a decent FSB. Start by reducing your memory and clock multipliers to work out your maximum FSB. Then work out the maximum CPU speed and calculate what FSB x multiplier you need.

After you've worked out the OC speeds and volts, use an offset voltage to leave the power saving features enabled.

This is fairly brief, but is covered in far greater detail earlier in this thread and elsewhere on the Internet.

usually volts are not fangerous, but temps+volts together. That means if you will have 1.6V in CPU and your temps will be up to 50 C in load, its OK. But if you will using 1.45V and your temps are most time around 77 C in load (Coretemp), its more danger than first situation

Just cracked and got a 8370 to give me a bit of a boost over my 3.8ghz 1055t :D

Hoping I can break 4.5/4.8 with sabertooth r1 and akasa venom dual fan.

If you had a thuban at 4.1-4.4ghz then you'd be underwhelmed by the fx8 unless you were way in the 5ghz range, but you should see a little improvement in some game titles, in particular handbrake encoding.

10 to 20% bench's suggest now but honestly I can't say anything I've played has required a CPU upgrade, I'm changing the case and thought since I'm getting the mobo out I might as well take the time to update the CPU.

The itch is just overwhelming after 3 years since my last purchase (a 7970) and 5 for the processor!

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.....

Nice work dude.

Your first link didn't work by the way.

Got any rig pictures? What's your twitter handle?

The main thing is you have a good board which you can reuse,also the thubans sell well second hand so it's worth buying the fx8 even on the cost factor.
With modern titles the Fx instruction set should provide greater throughput, but out of the box performance is poor due to the apm and excessive voltages. When you tweak the fx's they start to become viable cpu's, but they still lack the oomph in particular games.

Like yourself I still use a 7950 and a 2600k. When I used to have an fx8320 I compared the fx8 to the phII x4 and 2600k, this was around the time of far cry 3. I wasn't overally impressed with the fx8 but I did have fun tinkering with it in lot's of games and software.
 
New toy testing....After long time I can tetsing next FX, now FX-8320E. Meantime looks like good CPU for some fun. Im strating from lower values of voltages and goind in smaller step up if my temps are OK.

So, in first day of testing I used 1.4V for CPU and 1.25V for CPUNB and 2.6V for VDDA. If someone will ask me if the FX-8320E working at older motherboard Asus Crosshair V Formula, I can say YES.
Of course, there is not last agesa code (as example more modern Crosshair V Formula-Z) but for performance seems very similar.

First few photos of testing PC


Light in objective :)


Do you see FX logo at cooler/pump?:)


And few test at 4815 MHz, 1.4V in BIOS, LLC high etc...:)

Cinebench R15 - this Cinebench is from my point of view not so objective to the performance as older R11.5. I think, Intel codes are more positives, special Haswell CPU :)


Cinebench R11.5 - older version, but still good rendering schema. Its a bit less stressfull than R15.


Wprime 1.55


GPU PI by CPU 100M and 1B (modern version of superpi)




For first post its all from my side :). I hope, it could be very good piece of CPU, depends on others modules. Usually one module is cripled around 5 GHz Cinebench run and must be aligned by high voltage for complete 5000-5100 MHz test. But sometimes are the chips who are able running at 5200-5300 MHz with 1.55V and AIO cooling or very highend AIR cooler. Remember guys, custom watter cooling setup will be always +100-150 MHz better than AIO cooling.

Flank3r interesting you have a fan over AIO cooler on the cpu - seriously loving my 8320E - one of the best overclockers I've had in forever.....

3.2 Ghz to 5.055Ghz without breaking much of a sweat :D might try the fan over my iH80 to see if I can push her even higher :D that's with all modules; I possibly could hit 5.5 if I took out a module or two :D

As I've said' most fun I've had overclocking since possibly the original Athlon :D
