Amd overdrive vs Bios cpu overclocking

[Tackett351]

Got a good one for you guys, so I've overclocked a few cpu's in my day through the bios and as old as moving jumpers back in the AMD 350mhz days on an old asus board back when there really weren't any synthetic benchmarking tools to test your results, Anyway what I'm here to ask is how am I getting better per core and all six core performance scores using AMD overdrive over using the bios to manually plug in the same setting I'm using in AMD overdrive to achieve the 4.5ghz on my FX6300? CPU Z is my benchmarking tool. Is there something overdrive is dynamically controlling I can't see? I'm baffled by this results and they seem somewhat backwards as using software would theoretically take more cpu power to run right?

Check to see if the overclock is actually stable or not...I remember AI tuner for my 2500K said 4.9GHz was stable when it was far from it. It also wanted to pump 1.5v into the CPU. I remember on the extreme preset, it went to 5.2GHz and the vcore was getting stupid (1.55v+...). Also check the vcore to see if it's actually reasonable to run (They tend to overshoot a lot)

 

My manual overclock (within reason for vcore) was 4.6GHz / 1.38 vcore.

It's stable as I'm not getting the blue screen unhappy face lol! But I'm running what I would consider undervolt really as when amd Turbocore is enabled it jumps over what I have my voltage set to, wich is 1.2625, also another thing to note is, if I change anything in the bios other than leaving the stock settings for this chip it negates the gain I'm receiving from AMD overdrive, even disabling Turbocore in the bios, even tho I'm turning it of in the application anyway so its not throttling my overclock. Mind=blown I know

Have you run a stress test though? Prime 95 / Intel Burn Test / AIDA64?

 

Hmm, that's interesting. Well, I hope it works out for you...my experience with software overclocking still is pretty bad so far...though I'm mostly OCing on the Intel side of things. I didn't even know AMD overdrive existed to overclock CPUs.

Please don't not compare shitsus Ai wrecker to overdrive. 

 

Overdrive stresstests the cpu at 100MHz intervals until it crashes. IT actually works. But you can get lower voltage from bios tweaks.
