Athlon II is relatively lower power part. 400MHz isnt that much.

I would say it is fine. Maybe put a fan facing the VRM area or something if you want to be safe.

Would you say I reached my OC limits at 3.5mhz?

Honestly I am afraid because all I did was raise the value of the FSB in the bios without lowering any other values.

If I want to overclock any further would you want me to return this and purchase a better motherboard, for say an ASUS motherboard?

I would rather not pay extra and change my motherboard but if it has to come down to it I am willing to pay a few extra dollars to not risk destroying my rig.

At 3.5ghz i think the risk is minimal.

I think you're overstating the importance of mosfet heatsinks. Sure they're good to have, but you can still have a decent overclock with alot of the motherboards on the list you recommend not overclocking with. I'm currently overclocking on two of the boards on the not recommended list (MA-880GM-UD2H 1100T@ 4GHz 1.45v and M4A88T-I Deluxe 1055T@ 3.94GHz 1.475v) for a while now and these computers do alot of heavy lifting.

You're fine, no need to spend more money for nothing.

Better to spend $10 on mosfet heatsinks than $100+ on a new board

Feel free to prove me wrong though. Also been running my overclock with high-ish volts (maxes out at 1.5v) with Cool'n'Quiet disabled, with no issues.
Fix it pretty please

All of AsRock's Extreme4 boards are 8+2 designs.

The Extreme3 870 and Extreme3 770 are only 4+1 designs.

The Ex3 870 can handle quads without an issue, the Ex3 770 needs some MOS-C1's as it has no heatsink on the VRM's.

Ouch, both seem dangerous
880GM-UD2H: 4+1 phase with known problems, old design from Gigabyte
M4A88T-I Deluxe: Not even rated for >95W processors

I just recently OC'd my Athlon II X4 645 to 3.5mhz(originally 3.1mhz) by raising the FSB to 230. Based on what I've seen in this thread I believe it's best for me to downclock it to original speeds? Am I missing something
Well, pioneerisloud had this board VRM-fry on him with a stock 95W TDP Athlon II x4 on stock cooler... not that that is probably going to happen all the time, but this board with these VRMs & similar designs is known to be finicky on higher TDP processors

------

Adding 990FX-UD7 to the list now that there are screenshots. It is 8+2 and Driver MOSFET, something I haven't seen before from GIGABYTE

Circumstances forced me to go inactive back in 2014. I guess I'm back for 2016, but won't be active much! Cheers!

Like all of their top end boards have driver mosfets...

not really new.

What could you expect from a simple thing as a VRM .They can t be revolutionary.
You can t reinvent the wheels ,but you can put better tires on them.
It s the quality of the components used that counts mostly.

What about FM2 motherboards with 2 APU sockets and GDDR5 on-board AMD ?! smile.gif

Maybe i am to sarcastic sometimes smile.gif
