Envy 15 (CPU PLL & GPU oc)

Hii,

I wondered if it's possible to OC your CPU part.
I own a i7 720QM and it's pretty fast, but it only clocks @ 2.4ghz when dualcore mode hits in. That's quite low, considering a i3 part can already get those speeds.

Anyway I read things about clockgen and setfsb. But it seems you need a PLL number to get it work. I don't know the number is motherboard or CPU related?

Anyway does someone managed to OC the cpu of the envy 15? I would already be happy with a 2.53ghz or 2.66ghz speed...


Now let's talk about GPU oc. I currently have the 1st gen of the envy 15, which included a 4830 mobility.
I already managed to get 567/999 with a nice overclock. But I wonder if it can't go further? I get artifacts around 1020 memory, but temps while running 3dmark are just around 65C. Whould a higher voltage be a solution? (1V instead of 0.95V)
But with AMD GPU clock tool you can only select one option. Any ideas to oc further or change the voltage (lower voltage can also be good for battery!)
I would like to do it on a nonBIOS way, but if there is no other solution... tell me
What about radeon bios editor (RBE) program?

Thanks,
Devenox

nobody ??

 

currently there is no way to overclock any of the new ix cpus.... and you are not able to change the voltage on mobile gpus

 

It's possible on some mobile cards, in both ways (under and overclocking)

 

bump for comments

 

bump? Any one found the pll?

 

You can if you dare to extract the vBIOS off from the Insyde BIOS and mod the hex codes (check out the HD 5650 OC Thread in the gaming section, it is doable). However it is highly risky.

Also RBE I heard doesn't work (I think I even dabbed with it on my Envy once and it totally didn't work). What you have to do is use Phoenix BIOS Editor (or something like that) and extract the HP BIOS and specifically the ATI vBIOS that is embedded in it, then use the Hex Editor to modify certain codes in there that relates to the voltage and then recompile the entire vBIOS into the BIOS and flash the modded BIOS. Highly risky and complicated but it is doable. Check out the thread I mentioned above for more details. Now that being said, the HD 5830 only runs on the voltage setting of .9000v. I don't know where you got .9500v from. Also, a jump from .9 to .95 is pretty high, and that alone could overheat the GPU, let altone .9-1.0. Also, overvolting usually helps the core clocks OC better, but I also heard that memory controllers can also get a bit of benefit as well from a overvolt and would also stabilize a memory clock OC, but the boost on memory clocks is still significantly less vs. a core clock OC with a overvolt and it is also dependent on the memory chip's tolerance as well, as a high voltage will fry it if you go beyond it's tolerance levels.

Edit: Oh never mind on the voltage count. You got a 4830, so that explains the .95v. Mah bad, but the explanation of a +.5v boost still stands.
