upok Posted October 28, 2007 Posted October 28, 2007 Oc'd q6600(SLACR), things are stable at 3.2~, 1.36~ vcore(1.31 with vdroop), OCCT stable(30 Min), but when I use OCCT I get a high pitched, barely audible whine, or maybe a squeal?! Is that from overvolting the board? I've heard about whining mosfets, is that what this is? Board voltages are: fsb 1.4 spp 1.40 mcp 1.5 spp<->mcp 1.4 Any help would be appreciated. Oh and it only happens with OCCT, not orthos, or superpi on 4 instances, not during gaming.. I dunno. Share this post Link to post Share on other sites More sharing options...

hardnrg Posted October 28, 2007 Posted October 28, 2007 I don't think mosfets can whine as they are semiconductors. Inductors make the whining sound, and it's almost always inductive coils of copper wire. Share this post Link to post Share on other sites More sharing options...
Waco Posted October 28, 2007 Posted October 28, 2007 My old nForce 2 and my nForce 4 Ultra squealed when heavily loaded and overclocked. My old X850XT did the same thing when loaded down (even at stock speeds). I never worried about it. Share this post Link to post Share on other sites More sharing options...
upok Posted October 28, 2007 Posted October 28, 2007 My other topic Normal with the 680i reference boards. So, it's nothing for me to worry about? Just keep on oc'ing? I don't think mosfets can whine as they are semiconductors. Inductors make the whining sound, and it's almost always inductive coils of copper wire. Good point. Like I said I just saw it in another forum and was trying to isolate to problem. Inductor whine seems to be the most logical solution, thanks.

suchuwato Posted October 29, 2007 Posted October 29, 2007 It is indeed inductor whine... easiest thing to do is dampen it with some hot glue Share this post Link to post Share on other sites More sharing options...
