D830: Clock slippage in El Capitan with Clover

Recommended Posts

Indeed, it's required on all laptops with Intel 945 chipset, otherwise they KP. But it's not required on laptops with Intel 965 chipset.

 

'wondering if the OP's clock slippage could be fixed with setting the bus speed to 200000. If D830 is fitted with a Merom CPU, he should also ensure IDA is disabled in BIOS.

Hi, thank you for your help.

I have a D830 with Bios A17

Chipset ist 965 (I think but not sure)

My CPU is T7700, which should be a Merom CPU.

I tried the VoodooTSCSync.kext. Still I have a Clock slipage which is about 4 mins for 30 min uptime.

there used to be a voodootscsync kext for AMD that had a faster sync rate then the normal voodootsc kext but i think it was on projectosx site. you can try messing with clock/buss speed like herve implies also in clover gui so that it is not permanent untill you get it to sync.

It seems to be ok now. No clock slippage for 30 mins uptime.

IDA was enabled (Intel Dynamic Acceleration). I disabled it.

As explained here

If you know what to look for :-)

 

Thanks again for your help.

Hi,

I change now my CPU to T9300 to be ready for Sierra. 

My machine D830, El captain, NVS140

Clock slippage is back again. 

I changed nothing else. Any more idea?

Please help...
