***official amd 83x0 overclocking thread***

[jimbaw]

Which cooler do you have? Interested in how high you can go with just air cooling - I jumped straight into water when i got my 8350!

a xigmatek loki
not the best but I'm at 4.4ghz with manageable temps.
I'm going to tweak my OC to see how far I can go without problems.
is a safe temp for 24/7 OC about 62?
I still can't find a proper answer anywhere

Throttling occurs around there yes so you may see it perform worse than a lower clock.

 

[jimbaw]

ok thank you

Will be getting a new system soon and was wondering if anyone has experience with the Alpenföhn K2 Mount Doom CPU Cooler on the 8320, will it allow me to push it a little?

I have my FX8350 sat at 4.6GHz on just the multi. (24/7)

Alpenföhn K2 Mount Doom, Sabertooth board, Kingston HyperX Beast, GTX590.

All housed in a HAF 932.

Never goes above 58 deg on Prime/OCCT/Folding.

Took this screen snip while folding.

I am happy at this ..... but, could it do more on air...? One wonders..

Could try the mixed fsb/multi clock, may help. 4.6 seems good though!

 

[gpuerrilla]

I get to about 4.7 before it starts to warrant fine tweaking. For running 24/7 I would say 4.8 would be your max on air.

Just unparked my cores.....so much smoother gameplay in DayZ....

This FX chips handle heat really well and they are soldered too so dont worry.It will start throttling when the core hits 72°C.It would take years to really break one.And if you do you just buy another cuz its cheap as dirt!

Hi Guys,

Been lurking for a bit around various forums and really liked your approach to overclocking as to test it in a real world situation rather than to see if our chips are made of asbestos and Prime them to death.

A few questions though if you'd be so kind to enlighten me:

1. It's been mentioned to cycle cinebench but is there a way to do this as all I can see in the program itself is the option to manually keep running it?
2. I'm interested in trying the FSB method of overclocking but should I drop the multi as low as it can possibly go on my board to find my max FSB as in the BIOS I could go down as low as 4 IIRC! Seems way to low to do the stability test
3. I'm currently sat at 4.8ghz with temps at around the mid 50's when running cinibench and Linx so is there any more room to be had on this chip in your opinion? Currently running a Silver Arrow SB-E Extreme and have a NZXT Phantom 530 with pretty good cable management and airflow.

Anyway guys, been picking up a lot of good info in this thread so keep up the good work showing there are alternatives to running your chip into the ground just for bragging rights

my mutli goes down to 4 as well so i'm interested in knowing as well.

4.8ghz stable is quite good! the only way to know if you can go further is to try it I think.

 

[cwgk91]

Take the multi down to 4 while raising the bus is only to test how far the clock will go without having to raise the voltage. To do this, you only need to see if windows will start, no need to stress test as youll only have 1Ghz or so so definitely wont be stressed!

If windows starts then you raise the bus more, etc. Once it fails to start, then you go back one bus freq, raise multi 'till you get the clock you want, while adding voltage for stability. Then you stress test with your desired program

Brilliant, might give that a ganders this evening then. At the moment I'm on a 1.4v overclock with high LLC and it seems to be performing quite well. I've not bother reducing it further as the temps are fine for my use so I'm hoping the FSB might allow me to push it a little bit further on similar volts

 

[jimbaw]

Just tried it and if my multiplier is all the way down, windows start with my fsb at 230 but as soon as I raise my multiplier, it won't start. Looks like my limit for the fsb is 220. I've got my multiplier on 20 so I've got 4.4 stable with temps of 60 (socket) and 58 (cpu) under full load. That's with my voltages at stock.
Would I be able to raise my fsb with more volts or should I now focus on my multiplier?

If it can't boot with stock volts then I don't think adding more will help, as your multi is so low (4x230Mhz = 0.92Ghz...) adding voltage for stability shouldn't be necessary, thats why you lower the multi to lowest possible. What about 225Mhz fsb?

it wouldn't work with 225 unfortunately. looks like i'll be stuck with 220

 

[cwgk91]

Still an increase on baseline

Which motherboard are you using out of interest?

 

[jimbaw]

Gigabyte 990fxa ud5
Without the multi I can get it up to 230 and still get into windows

 

[ll-Nightfly-ll]

So I had a bit of a tinker round with this new idea and managed to get my FSB up to 285 and still manage to log in to windows. Got panicked at first because it took so long but then realised my system was only chugging away with less than a single Ghz! haha

Anyway, when playing around with the FSB I could get it relatively stable at 4.8ghz (linx and cinebench, didn't do any gaming though as I was pressed for time) but it still required the same 1.4v which I was expecting I'd be able to get away with a little less to help with temps.

Don't get me wrong the temps are fine and only peaking at around 53ish degrees when under heavy load but I was hoping using this method I could reduce my required volts and thus temps allowing me a little more headroom.

Also, when doing this I have changed the power saving functions and some of the LLC stuff but left everything else to auto. I've noticed when I do this though my memory timings go way out of whack compared to the rated 9-9-9-24 that it should be. Any thoughts?

 

[cwgk91]

If you benchmark with cinebench, I found that although temps and voltages are roughly the same, the score went up (managed to get 796 with my fsb at 270 compared to 740ish with fsb at stock, both at the same 4.8Ghz).

You have to set the ram settings manually if you mess around with manual functions for some reason

@jimbaw, never used a gigabyte board but on my asus I can change the power mode to asus optimised, maybe there is something like that on the gigabyte which could help stabilise?

I've got all my settings optimised (I think) so I'll have another look see if I can find something similar.
If not, I'll just try with the multi for now.
