AsRock 970 Pro3 vs 970 Extreme3 , please help me

post #1 of 32
Thread Starter 
Hello. I can't decide between the two boards. The extra things that Extreme3 has are the heatskin on the VRM and digital pulse-width modulation (PWM).
In my country the price difference is pretty major between the two boards. I don't want to pay extra because the Extreme3 has heatsink on the VRM. What is that Digital Power (digital pulse-width modulation for the CPU Vcore) ? Do i need this ?
Will the Extreme3 perform better at overclocking ? I have lots of aftermarket copper VRM heatsinks that i can put on the Pro3 (or the Extreme3).
What are the major differences between these boards ? Which one should i get and why ? Please don't tell me that i should get the Extreme3 because of the heatsink on the vrm tongue.gif

Thank you and sorry for my bad English.

The Extreme3 *might* have better quality VRMs than the Pro3. Other than that, the heatsinks, and the arrangement of expansion slots, I can't see much of a difference between the two. I definitely wouldn't overclock without heatsinks on the VRMs, but if you can effectively apply them on your own, the two boards should be more or less the same for overclocking.

If the price difference was small, I'd definitely do for the Extreme3, but the Pro3 will work just fine.

Looks like the power delivery system is identical other than the heatsinked vrms. The only real difference is that the Extreme3 uses higher quality capacitors. Like gungnir said, if the price difference is significant, I'd go for the Pro3.

There is also another difference. The Extreme has digital PWM, the Pro3 doesn't mention it, so it's probably analog. Also, i know from a review, the Extreme has low rds mofsets, i don't know about the Pro3. Another difference in the expansion slots and SATA ports.

In general, i have read that the pro3 is poor overclocker. The extreme3 throttles too at some point, but the pro3 is worse. I don't know if adding a heatsink to the pro3 will solve this.

The overclocking capabilities of this board depends on the cpu you intend to clock with it.
post #7 of 32
I m not an expert in OC, as i am undervolting, but what i can tell, is that there is close to none voltage fluctuation with the digital one. My previous Asrock board was analog and the CPU voltage was going up and down all the time.

You may find this reading more helpful.

I don't know how much important is for OC, but the expensive boards tend to sport digital nowdays.

Extreme 3 is decent for clocking but that`s why i said depends on the chip, for example i own an extreme 3 990fx, it has the wifes fx4170 in it@4.7 but cant handle an 8 core dozer above 4.1, it has a 4+1 power phase which is not sufficient. The similar price board for us in the uk that outperforms it by a mile is the gigabyte ud3, top clocking board at the lowest available cost.
