Morning all,
Now last night I set about doing my overclock, everything seemed to be going swimmingly, hit 2.6 without problem with a brief 30 min orthos to test it before going higher.
So then onto 2.8 with vcore on auto, (it was pulling 1.28 at 2.6).
Booted into windows fine and then...no local area connection...no internet. Tried various things but to no avail, all other pcs fine in my house, routers fine switch was fine.
Couple of restarts and still nothing. Cleared the CMOS and back to stock...no problems at all, LAN is fine!
Anyone know what on earth is going on?
Or is this another failing of my psu just not being aboe to hack it.
thanks

I think it's something to do with the PCI-E frequency, newer onboard lan uses PCI-E x1 lane rather than traditional PCI so you'll need to lock the PCI-E speed to 100Mhz when overclocking.
 
Hey all,
Just dragging this thread back up because I have just looked into my bios and it states that:
PCIEX16_1 Frequency (MHz) [100]
PCIEX16_2 Frequency (MHz) [100]
PCIEX16_3 Frequency (MHz) [100]

SPP<->MCP Ref Clock, MHz [AUTO]

So does that mean that that the PCI lane that the lan controller is on is running at 100mhz?
And what does the bottom one set to auto do?
Cheers Mark
