Hi All, i am seeing 100-120 mv noise on Vcore @ 1Ghz, I think the spec allows upto 40-50 mv, with lower frequency processors noise is within spec just higher freq processor causes the increase in noise on the same board. I tried changing caps to oscon caps, that didnt help plus oscon caps are expensive, are there any other less expensive solutions to clean the voltage rail? Thank for the answers in advance.
