Overclocking: Asus Rampage IV Extreme Versus EVGA X79 FTW

By

Many companies claim to offer the best overclocking for your money, yet only two compete for the best overclocking at the very highest price point. Today we put those claims to the test, including a full set of benchmarks to analyze performance gains.

Benchmark Results: The Elder Scrolls V: Skyrim

We started this project a while ago, but Skyrim update 1.4.27 was still good enough to remove most of the game's CPU-bottlenecking tendencies. We’re left primarily comparing identical graphics performance to produce substantially similar performance results.

    Nice article.

    Where is the MSI Big Bang Xpower II? That's known to be a great board for overclocking as well.

    I'd love to see a comparison like this between the Rampage IV Extreme and the Rampage IV Formula. The price difference is over $100 and I don't see WHY. 8 RAM slots is something I would never fill up so the Formula and its 4 slots seems perfect to me.

    Kind of a lukewarm recommendation. Just 'Tom's Hardware Approved award'

    WR2Kind of a lukewarm recommendation. Just 'Tom's Hardware Approved award'Only because there aren't many readers who can get $50 of value out of its specific feature set, compared to the WS.

    I wish I hadn't seen this. I really do. I have no excuse to get an X79 based system. I don't. I..do...not. I want. ...but I can't. Food. Food is important.

    You guys really need to start Testing @ 5760x1080 !!! , Monitors go for really cheap on craiglist now from wholesellers , you can buy 3 24" leds for like 300 bucks so a lot of people that I know have been runing 3 monitor setups for a while.

    Thanks Thomas for another enlightening Article! :)

    Just knowing the ASUS and EVGA from past history (LGA 1366) which may or may not play any role here, ASUS tends to (lets call it adjust) the CPU vCore and VTT/VCCSA higher than advertised vs EVGA which probably explains* the problems with both the high frequency RAM and CPU OC's.

    The disturbing thing to 'me' was the regulator voltages. I know the EVGA uses 12+2 vs ASUS's 8+3+(2+2) PWM and it's all digital controlled on ASUS, (*)but IDK if the EVGA is digitally controlled which might explain the inefficiency and OC.

    The EVGA has always been a very 'manual' MOBO, so in that regard I'm not surprised you had to dive into the BIOS. I have no doubts if you raised the EVGA's voltages vs a cloned ASUS optimized OC set that you'd have no problems obtaining the SAME 4.8GHz OC. Both boards offer voltage check points and I'd be very interesting how they compared.

    Just the other day I updated my ASUS BIOS and right-off I noticed an increased vCore increase by +0.01v~+0.015v and as part of the documented (improvements) was 'Improved Stability' ; yeah sure if you raise the vCore or VTT/VCCSA, phase, etc profiles... Now I have to redo my validations.

    The most important testing here, to me, is the Baseline Comparison which tells me EVGA has some work to do ASAP, and hopefully a BIOS update can close the gaps. Further, personally I won't buy or recommend any X79 MOBO unless it offers an 8xDIMM option. In the forum it's been very clear which X79's I recommend since day one, and the ASUS R4E has always been on top on my list if you can afford it! ;)

    Considering Ivy Bridge is around the corner. Would it be beneficial in buying a Sandy Bridge-E board?
