Fiz o procedimento e funcionou perfeitamente com meu i5, Mobo DP55WB, agora não uso mais o NullCPUPowerManagement.kext.

E notei que o boot ficou muito mais rápido com meu SSD 120G, antes bootava em 19 segundos agora boota em 13 segundos.

O resultado é este agora...

What to serve?

To list wrmsr without patching

As it says, to list offsets that need patching, but don't actually patch them, just list.

If your problem was KP due to write operations to MSR 0xE2, yes you can.

[surfcaster]

following the thread of insanely understand that this patch is specific to Asus Sandy Bridge, fixes a problem KP, am I right?.

sorry for my English

[Cassio]

No, there are other mobos (like Intel and ECS) and laptops (most of the Sandy Bridge I have seen) that need this patch.

[MARIANO]

[Cassio]

This patch is ONLY intended to avoid KP caused by write operations to MSR 0xE2, it's not directly related to sleep problems.

Hi Cassio ...have you a news for patched Bios ?

I ready a news for edited CpuPei in the bios ...it is a great news..or not?

[Cassio]

Sorry, I don't understand.

If you use patched BIOS, you don't need to patch AICPM kext.

[magnifico]

Sorry, I don't understand.

If you use patched BIOS, you don't need to patch AICPM kext.

 

No, I'm not using the patch bios, I ask you if you have news about a patch bios asus.....

I read a news article that you just change the hex values ​​of the two CPU Pei mmtools with the bios, and 'All this safe?

[Cassio]

I've heard about these BIOSes, but never used, don't know what's edited or if it's safe
