Southbridge Intel X38/X48 while OC

[newfellow]

Well, perhaps some smart one can answer me on this. On stock seems SB being 1.100v exact every setup I build, but when you add some decent overclocking (seems what ever OC). The board south bridge voltage always drops to 1.072v-1.088v (jumping).

Usually working with ASUS boards. Maximum Extreme, Formula, P5Q (P45), P5E, etc etc..

Now, should I add/modify on BIOS the usual stock 1.100v back to this chip while OCing or just let it be what ever it goes?
(just for mention this isn't an PSU issue I've has tested since building more than 20 different model power supply's every single one does this same. With very many boards and BIOSes.)

i wouldnt bother unless you've having stability issues with devices attached to the southbridge. all electrical parts of a PC get voltage droops on load, they design them to handle it (stock voltage is never the minimum they need, its always got some room)

Werd, but it's close to minimum.

Yeah, but I found on some really high OCs that this was the cause the lagging USB, All the suddenly none functional Network Adapter and Intel RAID controller also IDE controller was acting up time to time (Rarely but still).

(above happens on really extreme conditions only when you are on edge "450-500FSB". which is why I'm asking.)

-edit #1-

of course there's ways to get those all back with simply booting ones on NIC Boot ROM will restore the NIC and what goes to USB seems to stabilize itself or after full power cycle from PSU at latest with same voltage.

Only real question probably would be does it harm to anything to dump it back (since Drooping isn't exactly same as solid to stability for HDDs for example).
