How reliable is AMD's Overdrive mode?

I have a G73Jh m5870 graphics.

With the latest AMD update, I had forgotten what I had overclocked my GPU/CPU to, so I did the auto-tune that the Overdrive feature gives me.

Now it didn't budge my CPU at all, but apparently my GPU can get to 860. Can I trust Overdrive in this? It seems a bit high.

Also, any idea why it didn't budge my CPU at all? I've read that people can get 1100 safely, but the auto-tune didn't budge it from 1000.

I'd rather overclock my CPU as I play Rift extensively and MMOs are more CPU intensive than GPU intensive.

 

that 1000 figure is not your cpu clock, its your shader clock (which is just another part of your gpu). Overdrive can only overclock the gpu, it cant do anything with the cpu.
860 is a bit high but if your card can handle it, i.e its running stable and not too hot, its not a problem.

if you want to OC your cpu, you need to get setfsb. There are several threads about g73 cpu overclocking you can search for em and read em.

 

Ah ok. So when people are saying they overclock to 800/1100, is the 1100 the Shader clock or is it the CPU?

 

800 GPU Core, 1100 on video memory

 

You always have the right answer Chastity. Thanks for being so Awesome

Anywho, do you recommend that I mess with my CPU? Or Is clocking my gpu to 800/1100 good enough?

 

That depends on the game. Normally I find OC'ing the CPU to be pointless with gaming. Experimentation is what brings joy to the soul.

 

Well I play Rift, which is cpu intensive. I think I may try Throttlestop first to see if that helps.

Would you recommend running that?

Also, experimentation can also lead to a broken laptop XD. I'm trying to experiment with caution.

 

You won't be able to increase the multipliers with throttlestop on a qm CPU, you'll either need a 920xm or a 940xm to increase the multipliers since they are unlocked. You will need SetFSB if you don't have one of those.
