In The Box

Back in the P67 days, if you remember the P67 Extreme4 by ASRock, for ~$160, we got a substantial haul in the box, including a front panel USB 3.0 panel and SSD holder.  No such luck for the low end here, as we have:

2 x SATA Cables
IO Panel
Driver CD
2 Slot SLI Bridge

I am a little disappointed to be honest, given ASRock’s previous tenacity when it comes to box bundling.

ASRock are starting to use Broadcom NICs on their products, as you will see with the Extreme4 later in this review and the Extreme9 in a later review.  As mentioned in the intro, it is nice to see a high end Realtek Audio Codec in there, even on a mATX board.  On the flip side, with the 4-pin molex CFX/SLI power connector on board in an odd position, one has to wonder whether it is really needed when other boards do not require it.

Overclocking

Over this year, I have had a number of ASRock Sandy Bridge boards through my hands.  On the whole, they tend to overclock well with one button settings, even if not able to overclock to the absolute extreme.  This is usually useful for system builders or amateur users wanting some extra bang for their buck.  But as we have already seen on the Patsburg chipset, these LGA2011 chips are hot beasts waiting to be tamed.  In order to keep everything the same, we are testing the same exact processor on the exact same cooling – the Intel All-In-One Liquid Cooler.

Initial impressions for the X79 Extreme4-M looked good, however it does suffer from various throttling modes to prevent high temperatures.  What I mean by this is that if you set the processor frequency high enough, and the cooler cannot deal with it properly (either it is not a good cooler, or clogged with dust), the system will reduce the multiplier to compensate for temperature.  This is all well and good on the majority of systems, however there was no option to turn it off in the BIOS (think extreme overclocking, or perhaps just experienced users).  So for example, if we set 4.6 GHz in BIOS, it would run at that speed in single threaded scenarios, but in multi-threaded tasks it would reduce back to 3.9 GHz.  Then, as per Intel specifications, the CPU would reduce to stock (3.3 GHz) if it was at full load for a certain time.  There seemed to be no way to turn any of these options off – the last point for 3.3 GHz is usually controlled by a timer stating how long Turbo can be engaged, but ASRock have not offered an option to disable it for ‘safety’.  Each to their own, but it really hurts anyone who overclocks the system.  The only way around this reduction to 3.3 GHz seemed to be to leave the CPU at stock frequencies, then it would only reduce to 3.6 GHz, as per Turbo core rules.  It is rather disappointing.

Nevertheless, I did go through the Auto and Manual OC tasks as usual to see what was possible.  In our Auto tests, we keep everything untouched as much as possible except the one setting.  During our manual OC of X79, we set a CPU voltage limit of 1.4 V for a balance of performance and temperature.

In Auto OC mode, the BIOS offers several options from 4.0 GHz to 5.2 GHz in 200 MHz jumps, with the final three in a red font, showing their ‘extreme’ nature.  I was able to start at 4.8 GHz; however the automatic settings on board gave the CPU 1.54 volts!  This was quite extreme, resulting in throttling almost immediately, but still reaching 83ºC in our multithreaded 3DPM test, with 3.3 GHz scores.

At 4.6 GHz, these issues still persisted, and the CPU was still receiving 1.54 volts.  However at 4.4 GHz, the system seemed stable, even if the CPU was getting 1.48 volts.  No throttling took place, until the turbo period was up and the CPU cut back to 3.3 GHz.

In terms of Manual OC, I set the board to give the CPU 1.4 volts, and rose the Core Current Limit to 500A, to stop as much throttling as possible.  Using this, I was able to reach a 47x multiplier, giving 4.7 GHz.  In the OS, the CPU was recorded as receiving 1.456 volts at load, presumably due to load line calibration.  At full multithreaded load, the CPU would reduce back to 3.9 GHz, and reach 71ºC when under 3DPM.  After the allotted turbo time, the CPU would again reduce back to 3.3 GHz.

For the memory overclock, this was a bit frustrating.  I am currently using a 4x4 GB set of GSkill RipjawsZ (DDR3-2133 9-11-9-28 1.65 V), in which I have had them running at 2752 MHz (even though at silly timings of 13-13-14, but still with 1.65 V) with Llano.  However, it seems the Integrated Memory Controller with my LGA2011 chip is not that good.  While we were able to set our XMP profiles on the memory, the next divider up was at DDR3-2400.  In order to be comparable to XMP, I reduced the timings to 10-12-10-31 2T, but after one successful boot, it failed to get into the OS after many attempts, and thus is not stable.

    Maybe you could explain why you think they're wrong rather than just calling them names. They seem to be pretty much right-on regarding the point of having swap/pagefile on disk. Reply

    You guys surely must have got more modern drives lying around, especially when Anand is constantly reviewing the bleeding edge!

    I would have liked to see what this board can do. It is for enthusiasts after all, isn't it?

    Benchmark platforms can't change rapidly. When they do you can no longer compare new scores to old. As a result the parts not being compared typically don't get swapped out until obsolete. Reply

    I don't consider the thermal throttle to be a bad thing at all. Throttling at 80c+ temperatures is good behaviour. Its a better guarantee for stability when you either have a cooling failure or are too lazy to have good cooling in the first place.

    Clearly these Sandy-E is the hottest overclocking chips ever from Intel.

    Basically, to overclock to the typical 4.7 Ghz range the Intel liquid cooling solution is insufficient. Not that surprising given the performance of that is probably about the same as a mid-range $40 120mm heatsink soluiton.

    To do a decent overclock you'll need a H100 or Noctua D14 at fairly high rpms or better still a real watercool loop.

    I was very impressed with the new ASRock color scheme and heatsink design....until the gratuitous use of "X" labeling distracted me. What a shame. (no need to read review now, it's too ugly to consider buying) Reply

    ASRock released BIOS update few days ago for Extreme4 version 1.60 and for Extreme4M version 1.50, which let's you overclock CPU 4.6Ghz for example with very low voltage. They updated C-2 Microcode etc. I am running i7 i3930k on ASRock Extreme 4 with < 1.36V. Temperature does not exceed 60C in Load. I always say reviews are so misleading when it comes to decide what purchase to make. Reply

    The chart say 6xDDR3 slots. Is that a typo or is that actually how it's setup? Reply

    Yeah, that's strange for X79. But it is 6. There is also a photo of it on the ASRock site. Reply

    Asus also released USB Boost, which is similar to Asrock USB XFast. I'd like to see USB Boost vs USB XFast in future reviews. Reply
