FX8350 Overclocking FSB vs Multiplier

1.6 is pushing it though as someone mentioned a bit too far.

AMD will leave a tolerance on there chips they won't be near the max voltage at stock.
FX8350 is stock 1.45v and people push this safely 24/7 @ 1.55v

To be honest I have been emailing AMD regarding the upgrade and even they cannot give a good reason to do so. I think I will stick with my FX8350 shame I thought AMD were finally pulling there finger out.

Not just with the CPUs but drivers, from what I understand AMD has not yet implemented Raid0 trim support for SSDs

What were you going to upgrade to?

Thats a decent improvement then. What fsb are you on now? pic doesn't appear to be working for me...

Fixed it. Bloody skydrive. Temps were good and after a couple hours of BF4 never went higher, time to up it some more!

I was thinking of a FX9590

No. They are just binned versions of your current chip, if you have decent cooling just get it near 5Ghz and save yourself some cash.

I agree with the general consensus of staying on 8350.
Now I read everywhere that stock voltage is around 1.4 however, mine is 1.296, 1.3 max. I've got it at 4.5ghz stable though so I'm not worried but I just findit curious. Also, sometimes, when I apply my OC, I get issues with my usb ports. Any ideas?

Does seem odd, but I suppose as the 83xx series gets older, they improve manufacturing processes, silicon gets better and better chance of getting better chips? hence Lower stock voltage. Who knows

Never had that problem myself. They work perfectly when OC not applied?

What voltage are you using for 4.82?

I use 1.47v for 4.7Ghz

Here is Realbench 2 score when @ 4.58Ghz (254 Bus):

Have we a RealBench 2 thread? Will take a look.

I'm using 1.428v for 4.82Ghz, with ultra-high LLC which means it sometimes pops up to 1.440v while priming

Pic still isnt working for me...

My realbench score is 64998 with a fsb of 260

Yes everything works fine at stock. Even with the oc, I get a message telling me that my usb device is not recognized but everything works fine. I still get an on/ off/ on cycle when I turn it on but everything is fine and stable otherwise.

How odd. Fraid I have nothing in the old memory banks to help.

Just fiddling around with ccc idly, has anyone fiddled with cpu overdrive? If so, does it work?

I find overdrive usless.

Also auto overdrive on the CPU goes to high without enough voltage mine went to over 6GHZ with 1.47V apparently? To the point it locked up but the worst thing is it automatically applies the OC on startup so you end up with constant crashes until you enter safe mode

cwgk91 · 11 Mar 2014 at 22:33

Ah, ok, shan't be trying that then

1.425V for 4.7 GHz my FX-9590

Delta of VID must be similar for low and high leakage and max Coretemp temps around 65 C in load (for shorter time up to 70 - example for some benchmark test with higher voltage and clocks)
Ussually, most of FX is OK with 1.5 V in load (LLC high or ultra high, no extreme) and with highend aircooler as NHD14 or Phanteks or H80/H100 allinone

Is the pic working for anyone else? I can see it but maybe 'cos it's linked to my account.

There was a lad on here I think Panos (who recently sold his rig and went to i7) that managed to let the software overclock doing it's thing. It isn't perfect though. I am just re-reading some old articles as I am sure the odd setting makes a hugh difference in stability. Some of the basic youtube 'guides' are pretty useless.

You own all those rigs in your sig Flanker? :O

Wow, only noticed after you pointed it out... Where would you keep them all??
