Question Highest MHz on a 8K3A/+?

What's the highest overall MHz people have gotten with their 8K3A/+ motherboards? I seem to have hit the wall at 2470MHz which isn't too shabby. I know my CPU is capable of more, but I think the motherboard has reached it's limit... maybe overcurrent protection? Dunno.

Just curious what other people have gotten to.

TIA.

Try lifting pin 16 on the cs5301 m8.

loose the OCP.

I think the highest I ever had mine was about 2.3, that was a long time aggo.

8K3A+ rev 1.2, air-cooled using ThermalRight AX-7/Sunon 80mm 50cfm fan:

Did 2400mHz with an XP2700+ (actually did 2485 with the same CPU but wasn't stable... 166 x 15.0... got the 15.0 multiplier by setting it at 7.5 or 8.0 or something like that in BIOS)

Currently running a Barton 2500+ at 2112mHz (176 x 12.0)... it's a new CPU so I'm not pushing it right now.

Hmm....
What that pin16 does?
And can you explain what OCP means?

Over current protection. I assume lifting pin16 bypasses that protection.

Thanks Holst.

Ok.
I got FX handle more FSB after feeding 2.0V to AGP so i´m now running 2563MHz (12.5x205).
This prolly belongs to other topic,but i have been wondering which makes NB unstable when VIO/mem voltage goes over 3.2V?
I had 3.23V which started to make computation error in Pifast.
By lowering it to 3.14V Pifast started to work.
I tried 3.46V and it didnt even load to windows.
AFAIK there goes other voltage to NB too which is possible to mod,but by raising only that voltage didnt effect anything....so would it need to raise VIO and that other voltage at same time to get it stable again?

I´m just asking if someone have tried it....i´m too lazy to put puter in pieces everyday.
