Test Setup and Overclocking

ASUS Maximus IV Extreme B3 Revision Review

Test Setup

As we don't have the time nor storage capacity to test long-term data integrity we are taking Intel's word for the fixes and expect the stock performance to remain very much on a par with our previous testing. So today we're going to be looking at the overclocking capabilities of the Maximus compared to our earlier test and another recent review.

Intel Core i5-2500K CPU
4GB Kingston Genesis Grey Edition
Noctua NH-D14
Cougar CM1000 PSU
Windows 7 64-Bit


This is the real meat of our revisit. When we first reviewed the Maximus IV Extreme our Core i5-2500K topped out at a disappointing 4.6 GHz. We know our chip is capable of 5GHz with sufficient, ahem, encouragement so starting off at what we'd consider a 24/7 voltage of 1.4v on the vCore it didn't take long at all to reach a stable 4.8 GHz. Already a massive improvement on the old Maximus as that wouldn't budge past 4.6 GHz even with 1.5v, which is what we use as a maximum.

One of the biggest innovations, and one we definitely enjoy, is the way we can just choose a memory speed regardless of the CPU speed. Our Kingston Genesis happily runs at its rated speed on the M4E without need to adjust anything.

Of course we don't just want to know what our "all day" overclock would be. Could this B3 revision make it up to the 5 GHz we've seen before?

With ease is the answer. So much so we didn't need 1.5v, but a mere 1.48v. Not only could it shift up to 5 GHz but it wasn't just a suicide shot. We managed to run all of our tests except PC Mark Vantage at this speed. If that isn't impressive then you need to check your pulse.

My name is Maximus IV Extreme, Motherboard to an over-clocked processor, foundation to a speedy system, and I will have 5GHz with this attempt or the next.

We could just bump the voltage a little to get through PC Mark, but we prefer to test at speeds we'd live with, because if we could you could and so you know what you're getting for your money.

Out of curiosity, is there a purpose for benchmarking video performance? Will there ever be a difference using different motherboards using the same clocks and hardware? Just curious.Quote

Good motherboard, i'm impressed. 5ghz @ 1.48v stable is good and i'm betting you could push it to 5.5ghz easy.

I'm looking forward to the Big Bang Marshall review now to see who comes out on top, the Maximus or the BBM.

nice 1 Bryan, good read that mate

how does it stack up against the ud7 and other higher end boards? only i thought the gd65 was a bit of a let down when you tested it Quote

The main reason to benchmark video performance is just in case there is some bizarre problem with the PCI-e lanes. Now and again companies add a NF200 or similar to their board, so we run the test just to make sure all is well. It also makes sure that the power-phases are fine and there aren't any bottlenecks anywhere. Plus everyone wants to know the 3D Mark scores, even if they never change.

How does it compare to the BBM? *whistles innocently*

As for the UD7, there isn't much in it tbh. But we could either have graphs that take a week to scroll through, or let you do a tiny bit of legwork. Tabbed browsing has it's benefits Quote
