Hi, I have a10 4600m es, and i cant overclock or locking the cpu clocks. I read all things but i can't do it. Bar-edit, pscheck, amdmsrtweaker etc. If i lock or overclock the cpu, games stutter or mouse lagging after overclock. I can turn off apm and turbo. Then simple, increase the cpu clock and increasing voltage for P0. The cpu works normal, for example at 2500mhz or 2700mhz, but in game low fps. The cpu and gpu can't work together, like you said.

I have a simple rig, a10 4600m es and 7670m. I am using 7670m at games. Do you have any idea, what is the problem? Not enought power? Limiting TDP? And sometimes if i success the oc, like 2900mhz(or locking 2400-2500), in game fps is good but stuttering, and characters moves fast, like 1,5x. I can't figure out. Ram things, nb vid? What can i do? I have es cpu but i give up for overclock, just want to locking 2,7ghz. Is this impossible to with cpu+gpu? Do you have any idea, what can i try?

Your problem is the clock control on hardware lavel. There is no way to avoid it. But you can trick it. Use amdmsrtweaker to assign the same values to all Pstates. (example for syntax: AmdMsrTweaker.exe turbo=1 APM=1 [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] [email protected])By doing it there will be the same frequency and voltage in all Pstates and there will be no matter in which Pstates your CPU is. Use WIn8 or 10 to avoid synch problems after overclocking. Win7 doesn't support properly mobile amd cpus.

anyone tried the prema vbios with the 347.25 drivers?

New Drivers doesn't allow overclocking on mobile Maxwell. It seems we need now modded drivers to be able to overcklock in addition to modded bios. Or it is time to start complaining to NViDIA so thay would return overclocking abilities to its drivers
