Overclocking with a Unlocked 555?

post #1 of 26
Thread Starter 
How much GHz could I get out of a unlocked 555? I hear C3 CPUs can go high, but some others say unlocked 55s can only go up to like 3.6Ghz

I've never heard this cap of 3.6. Talk... News to me.

Many guys with 555 unlocked achieved 4GHz and some of them 4.3/4.5GHz. Depend on what chip you got (poor or golden). You can see that with overclocking.

You'll just have to find out. You could get anywhere from 4GHz - 4.5GHz. Or even maybe only 3.8GHz. It is going to depend on your cooling and if your VRM quality on your motherboard... and of course the chip itself.

It's really a cap, but the core were disabled for a reason, therefore most people should not expect the 4.0 like a normal quad core chip.

Most people tend to get 3.6-3.7 with normal voltage. (Normal as in anything lower than 1.55v)

Probably for Demand as it has went up cause you can unlock. Don't try to go to go over 1.5v as you computer will turn into a Hummer saying "More Fuel!!!" but i think you should crank it to 4.0 with good cooling and a good VRM system.

How good will this motherboard do for Overclocking to 4GHz and overall unlocking the cores?

http://www.newegg.com/Product/Product.aspx?Item=N82E16813157281&Tpk=asrock%20990fx%20extreme3

Also, could a Hyper 212+ get the 555 unlocked to 4 GHz at relatively good temps?

No. Get a board with better VRM's. That looks like a 4+1 phase. (To the left of the CPU socket). A Hyper 212+ is a good cooler, but it would depend on the voltage required for 4GHz.

Dangerous voltage I'd say.

What are your temps?
