for my particular model. Also I used ComputerRestore's AMD Bulldozer/Piledriver Overclocking Reference Guide
as a template.
Back when I overclocked my 1090T from 3.2 to 4GHz all I did was increase the multiplier and manually set the CPU Voltage to 1.5 (that M4N98TD EVO board had a vdroop issue so manually setting it that way made it drop to around 1.4xx). I left the BUS speed at 200 because if I altered that in any way, Prime95 would shut down cores within the first 10 minutes. However if I left it at 200 I could crank the multiplier all the way up and it would cruise through Prime95 error free. I think I could have gotten even more out of it if I wanted as it was beyond smooth and stable at 4GHz...6+ hours at Prime95 and hours of BF3 (BF3 was the ultimate test as my machine would sail through Prime95 but crash on BF3) (These were my settings: 1090T Settings
My question: Is there an advantage to adjusting the bus speed AND the multiplier? Or should I try the same thing with the 8350 and only adjust the multiplier? My goal is to get it stable 24/7 at 4.8GHz. Not looking to squeeze every drop out of it or 5GHz, just want a solid OC with enough headroom that I can run it all the time and from what Ive read 4.8 is a good number. Im hoping I wasn't spoiled with how great my 1090T ran at 4Ghz lolCPUID ResultsWarning: Spoiler! (Click to show)
Before I got my 8350, I was running a 1090T as well and managed to get 4Ghz 24hr stable on 1.48v, with 2600Mhz NB and 2400Mhz HT. This was done like you, by simply increasing multiplier. I have done the same thing to my 8350, 200 FSB x 25 Ratio to achieve my 5Ghz stable at 1.52v. Correct me if I'm wrong, but I've heard FSB OC'ing might cause instability in your system as NB, HT, RAM will increase as your bump up FSB. Of course, you can change their speeds to match what they would be at 200FSB, but I've tried and did not get lucky anywhere. Could be just me being incapable of looking into FSB OC and sticking to multiplier OC.
If you're able to get 4.8Ghz at 1.48v, I'd say you should have a good overclocker as I am able to get that same speed stable at that voltage
