Vdroop Question

Message Topic Search Topic Options Post Reply Create New Topic Printable Version

   Just got to thinking....when Vdroop is enabled does it only affect the voltage on the Vcore, or does it affect all the voltages on the board?  I've only seen the substantial difference occur in the vcore voltage, but if that is the case then why is the vcore the only one that Intel requests it for under spec?  I'd just think all the components would have the same safety requirements.  If it does affect the voltages across the entire board, then if for example I had the VTT set at 1.25 and the DRAM set at 1.65 and a temporary spike occurred wouldn't it be possible for the two voltages to fall out of their .5 safety range?  Anyway I'm probably just confused on what its actual primary purpose is, and if someone could help shed some light on it I would be appreciative.

Thanks!

	Vdroop is just for V core. Vdroop is not a safety feature. Vcore is the only one, because it is the only voltage that has so much amperage draw to cause such a large sag in voltage. the .5 safety range is only a suggestion, anyways.

	and as justin pointed out to me, vdroop can make your coretemp/realtemp voltages even more incorrect, so be careful overclocking with it
