Ultimate Sandy Bridge OC Guide + P67A-UD7 Performance Review
Here it is in PDF format if you want to print it or read it on the go.
http://www.mediafire.com/?ala55zrlaaloqa7
With the release of Intel’s 2nd Generation processors, code named Sandy Bridge, come a variety of boards from a variety of companies that fulfill every need that can be imagined. Today I will take an in depth look into overclocking these new CPUs and take an in depth look at the performance offerings of GIGABYTE’s new P67A-UD7.
Previously I did in in depth analysis of the board and all of its various ICs and components P67A-UD7 in Depth Look at The Board
The performance review includes: Voltage read points, SLI performance, Overclocking and CPU performance, SATA6G performance, power consumption, and a look at some board features.Continue to Overclocking Made Simple if you just want to learn to OC, if you want to only see performance review click here:
Overclocking Made Simple:
If you are brand new to overclocking or a veteran from the Pentium 4 days you are in for a crash course in the “new generation” of overclocking to go along with a “new generation” of processors. Turbo multipliers are a new name for ratios and K series chips are the only ones that want to overclock past 4 GHz.
What you want to initially do is increase your turbo multipliers or CPU clock ratio. Now if your board is properly certified for Serial VID, you can usually tell by VDR12 Certified or if you’re VID changes after changing the multiplier. If this does not occur, skip down to the voltage section. If you board has proper SVID implemented you can keep reading (most do).

First you need monitoring and Stability programs. You need CPU-Z, at least one Temperature monitor, a stability tester, and one voltage monitor. You will also need a K series processor to overclock and a P67 Chipset motherboard like this one:
http://img801.imageshack.us/img801/7105/motherboard.jpg
REQUIRED: CPU-Z will give you processor frequency info as well as Vcore
REQUIRED: Stability program, Intel burn Test is popular as is LinX (they are basically identical), Prime 95 is also very good.
Required: Pick one or more or your own monitoring software:
HWMonitor will give you voltages and temperatures
Motherboard Software (such as EasyTune 6(GIGABYTE), TurboV(ASUS)): will give you voltages and temperatures as well as in windows voltage and multiplier change options.
Core Temp for Temperatures
Real Temp for Temperatures
Speed Fan: system monitoring
Step #1: Do not overclock RAM yet, let it run at stock frequencies. RAM is not like it was on previous platforms, it can run at 1333mhz and you can do 5.2ghz, believe me I have. Let’s tackle one thing at a time.
http://img816.imageshack.us/img816/5...sfrequency.jpg
Set the frequency you want for a high but modest overclock (not your final), something like 4.0- 4.5 GHz, set ratio or turbo frequencies (40x-45x), if you only have the option for turbo frequencies make sure they are all the same. If you are on a GIGABYTE board, and just want to use one Ratio setting, you can enable Ratio Change in OS option; this will disable the Turbo Settings (or you can also disable Turbo and OS Ratio Change).
If you enable Turbo Mode (which you do not have to and I recommend not doing) you will need to set each multiplier. Note that on many motherboards you do not have the option to OC without turbo, its ok, 52x multi is 52x multi whether its turbo or not. On GIGABYTE boards, enabling turbo shouldn’t make your multiplier go crazy, I have tested on the latest and even old BIOSes and you can use Turbo and the multiplier not drop. Turbo Mode or no Turbo Mode, your multiplier will stick steady. If for some reason it is jumping around, you have the option to disable Turbo Mode.
http://img543.imageshack.us/img543/9...sableturbo.jpg
I want to also mention that Turbo Mode, Real Time Ratio Change in OS, or even just disabling both make no change to your Overclock or affect its stability. The only thing that can help is with turbo mode you have the options to extend and set maximum TDP and TDC, I will talk about this later. If you have retail CPU please enable Internal CPU PLL Overvoltage option.
Make sure you DISABLE all of the following advanced CPU features (to stabilize multiplier and voltage):
C1E-DISABLE
EIST-DISABLE
C3, C6 States-DISABLE
CPU Thermal Monitor-DISABLE
Do not touch BLCK right now as it always needs to be lowered as you overclock higher, at stock or low OC (under 4.3 GHz you can increase BLCK no problem). Make sure you make note of Stock VID/Vcore/VCC (found under voltage options). Upon reboot if the system boots into BIOS check the new VID under voltages settings or CPU Vcore (VCC) under health monitoring, take this value and compare it to this:
Stock-4GHz on Stock VID
4.0-4.3GHz 1.300v-1.325v
4.3-4.5GHz 1.325v-1.375v
4.5-4.8GHz 1.375v-1.450v
http://img195.imageshack.us/img195/2159/initialvid.jpghttp://img24.imageshack.us/img24/2717/changedvide.jpg
Above you can see the VID change from 1.23 to 1.370 for 3.4 to 4.5 GHz automatically, if this occurs SVID is working properly.
If that fails to boot into BIOS, then set it to 4 GHz (40x), and SVID should work upon reboot. You should end up with a stable 4 GHz overclock with automatically increased Vcore/vcc. Those values listed above are optimal voltage for optimal overclocks up to 4.8 GHz. You want to stay within the low spectrum of those voltages for temperature and processor integrity sake.
Both my 2600Ks will boot into BIOS at 4.5 GHz without anything else changed, only multiplier to 45x, VID changes from 1.18 to 1.365 on one and 1.23-1.370 on the other. While both boot at 4.5 GHz into BIOS, one only can do 4.8 GHz while the other can do 5.2 GHz (the one with higher VID), both D1 stepping chips. Retail D2 stepping chips should be better overclockers.
P67A-UD7 Performance Review
P67A-UD7 Performance Review
I am now going to move on to the board performance review, first let me start by saying that the current BIOS is not the same as the UEFI BIOS that will be out shortly, and because of that, I feel there is no need to show off the BIOS, I provided screen shots of the BIOS for the most important Overclocking Areas above in the OC guide.
Board Spacing:
Focusing on the socket area we can immediately tell that this board has a very hefty VRM design. The board carries 24 phases VRM with Driver MOSFETS (24 of them) cooled by a low profile and very well designed elegant heatsink. The air cooler used in all the testing is a LinSpire Eclipse II, a 5 heat pipe efficient air cooler that tops the charts in performance figures.
Here you can see how the cooler fits with a hefty aftermarket 120mm fan:
http://img715.imageshack.us/img715/600/fanclearance.jpg
As you can see above, the low profile design of the heatsink makes it possible to fit large fans. Around the socket Area we have these shiny cubes that are called Ferrite Core Choke, as well as a small bank of capacitors. In the Intel VRD 12 PWM spec sheet, there was an interesting sentence that read: A faster VR with a small bank of capacitors will provide better end user experience than a slow VR with a large bank of capacitors. Gigabyte took that to heart, and provides the entire P67A line of Ultra Durable 3 boards with extremely high quality Driver MOSFETs, Chokes, and Capacitors. Ferrite Coke Chokes are basically high quality inductors; they reduce electromagnetic interference, noise, flatten current spikes, and filter high frequency signals. They are perfect for motherboard power regulators. Driver MOSFETs make it possible to reduce the overall footprint of the VRM on the motherboard by combining traditional 3 chips into one, a high side MOSFET, a low side MOSFET, and a driver chip. Now they all fit into one integrated circuit. Driver MOSFETs can be fed a range of voltages, such as 12v and then reduce that voltage to 0.5v-2.0v for the CPU. Sticking with same powerful Driver MOSFETs from the X58A series of boards each phase can output 35amps of current continuously. The CPU has a TDC of only 110amps. Capacitors are used to reduce voltage ripple, to provide a constant clean power. Capacitors do this by storing and electrical charge, and then discharging when needed, the discharged electricity would in theory have less variance, and testing proves that capacitors do their job. By using such high quality parts for the rest of the design, GIGABYTE was able to reduce the number of capacitors needed. Gigabyte uses an Intersil PWM, which is why the voltage when set to auto can correctly set its own value. This is due to the fact that the VRM and CPU can talk to each other and decide upon the best VID for the current frequency, and you don’t need to reboot for this to happen, the voltage will change on the fly.
This board's VRM is VRD12 CERTIFIED, it is very important certification that is hard to meet. It depends on VRM response time as well as other factors. This is something to look for when buying a board, because VRM response time indicates how fast the turbo multipliers can change. This board has no lag when using turbo mode. It is an Intel Certification.
http://img440.imageshack.us/img440/8...pheresmall.jpg
Let move on to the other side of the heatsink, the side where the RAM modules are. There is much concern with the spacing between the CPU socket and the RAM. While this might be a cause of concern, it is due to two reasons. The increase in the distance of the traces would decrease electrical performance and this design is by Intel specifications. Most RAM modules like my Dominator set have detachable heatsinks, here are a few shots.
http://img835.imageshack.us/img835/9949/testsetup.jpg
http://img146.imageshack.us/img146/7...uhsspacing.jpg
As you can see with the heatsinks off the RAM modules, clearance is a little bit less of an issue; a taller cooler would make a good fit if you want to add a second 120mm fan.
Now here is a shot of the problem with a large 120mm fan, the fan sits on the Ram modules:
http://img8.imageshack.us/img8/6825/badclearnace.jpg
Of course you can make it work, but it is still an issue. You can always move the modules into different slots to accommodate the fan.
Now let me move onto PCI-E slot spacing. As you can see you have a plethora of PCI-E slots, the first 16x slot is the topmost normal size PCI-E slot, underneath it is a 8x slot, and below that is another 16x slot, and below that a PCI slot and another 8x and another PCI slot.
http://img543.imageshack.us/img543/5...iareasmall.jpg
Here is a look at spacing with two large GTX570 GPUs and a 3rd GT220 for 3-way SLI. Notice that you can fit another dual slotted card in there very easily.
http://img259.imageshack.us/img259/9...slispacing.jpg
Here is a shot of the cards moved around, notice there is one PCI-E slot available with the setup above, and when moving the second GTX570 to the bottom 8X slot it is possible to still have a PCI device and a 3rd single slotted card:
http://img402.imageshack.us/img402/3...6xspaciong.jpg
Now here is the cool thing about the PCH heatsink and angled SATA connectors. There is just enough clearance for these huge GPUs.
http://img502.imageshack.us/img502/3...rnaceagain.jpg
Here is SATA clearance:
http://img30.imageshack.us/img30/8900/sataclearnace.jpg
There are no issues for clearance with long XL GPUs.
P67A-UD7 Voltage Read Points
Voltage Read Points:
I found these points to be the voltage read points for the board. Now I do not have the Data sheet for the ISL 6366 PWM for the CPU so I just indicated voltage read point off of one of the Core Chokes.
CPU Vcore:
http://img832.imageshack.us/img832/4...ereadpoint.jpg
CPU PLL:
http://img411.imageshack.us/img411/2...lreadpoint.jpg
QPI/VTT + System Agent:
http://img9.imageshack.us/img9/2228/vttreadpoint.jpg
DDR3 Voltage:
http://img338.imageshack.us/img338/5...qreadpoint.jpg
Voltage Read Points VS Software and BIOS and Load Line Calibration:
I took manual Digital Multi Meter readings of CPU Vcore, CPU Vcore LLC 1, CPU VCORE LLC2, QPI/VTT, and DDR3 Voltage. System Agent and CPU PLL voltages were only taken from what is set in BIOS to what I found on the board. Now I did not spend much time on this, so if you find a better read point let me know!
http://img526.imageshack.us/img526/9...ltagetable.png
Percent Difference:
Average Vcore percent difference: 0.5% difference
QPI/VTT percent average percent difference: 0.1% difference
DDR3 percent average difference: 0.6% difference
System Agent percent difference: 2%
CPU PLL percent difference: 1.5%
It looks like the Ite voltage monitoring super I/O chip is doing its job. The voltages you should be most concerned with are Vcore and VTT, and they are almost dead on (VTT is really dead on). Now this board is for enthusiasts, so I am sure many will use read points, but software is just fine. You can use the above data on Load Line Calibration to see what level you want to use, if any at all.
Power Consumption:
Here are figures at the socket (the wall) power draw by the PSU, keep in mind that the PSU is about 85-90% efficient, so actual total power draw is about 80-90% of what is stated. Also keep in mind that each of the two GTX570s used has a TDP if 210Watts, so you can subtract 400watts from the load figures to get a rough estimate of board/CPU power consumption. Other than the GPUs, and 1 HDD, RAM, and 2 high power fans, nothing else was powered by the PSU. For load, I used Intel burn Test 8thread maximum level, and Furmark after disabling OCP on the GTX570s, OCP was enabled for all the other tests.
http://img143.imageshack.us/img143/3...ttagetable.png
Now I am going to do some estimation. First multiply by 0.85 for the PSU, then subtract 420watts for the GPUs, then subtract 20 watts for the HDD and 10 watts for the Fans. Now these are rough estimates, and the wattage meter is not perfect, I would give these results about 3-5% error. BUT they look fine, stock numbers on the 2600K are good, the stock TDP is 95watts plus motherboard and Ram would be about 117 watts. On the i7 930, TDP is 130watts, and results are 143.3, now that is a little low, but the Kill-A-Watt meter I used isn’t perfect.
But what is perfect is the reduction in thermal leakage of the CPU, these CPUs run at much higher voltage and amperage (most likely) yet run much cooler. Just like the 6-core Gulftown 32nm chips have the same TDP as the 45nm Bloomfields, but the Gulftowns have 2 extra cores. These numbers look about right, and I did need a 1K PSU for the GTX570s. If you are looking to buy this system, it looks like the motherboard is very efficient, with all those power phases you are probably at 90-95% efficient at the CPU socket, based on the efficiency rating of the MOSFETs.
CPU/ Board performance testing VS X58 system
CPU/ Board performance testing VS X58 system:
Here is a pic of the Sandy Bridge system in my case after testing was done.
http://img406.imageshack.us/img406/4521/beautifuly.jpg
Overclocking settings per chip:
Stock means loaded stock defaults, 1333 MHz ram cas 9 for P67A-UD7 and 1066mhz cas 9 for X58A-UD5. For the 2.8ghz 2600K memory speed of 1066MHz at 9, 9,9,24 was used to even out the bottom comparison line. In some memory benchmarks I used another setting as well with the 2.8 GHz 2600K at 1333MHz to compare speed to stock 3.4 GHz 1333 MHz; same timings were used for all runs, except max OC. I made note where any setting was changed.
Test Systems:
http://img193.imageshack.us/img193/2922/specsx.png
CPU Performance Benchmarks:
SuperPi Mod 1.5 XS, this program calculates Pi 22/7 to the 1 millionth digits, it’s a good indicator of overall CPU/RAM/motherboard performance, and usually is an indicator of pure speed. 5.2 GHz overclock was included.
http://img816.imageshack.us/img816/7756/superpi1m.png
Now 32 million digits
http://img254.imageshack.us/img254/7761/superpi32m.png
As you can tell from the SuperPi results, the 2600K is one fast little sucker. This processor clock for clock beats out the i7 930, remember the 2600K at 2.8 GHz has the same RAM speed as the i7930 at stock.
Now let’s move on to Intel Burn Test, not only does this program test the stability of your system, it also takes all threads to 100%. It has a Giga Flops output that is more consistent than LinX. Now this test also has a result for 5.2 GHz, I need to clarify, that it was one pass, and the system froze up afterwards (b/c of cold bug), I had to use extreme cooling for that test(to maintain heat). I took a picture of the results with my camera. The other results are pretty consistent, all done on air.
http://img713.imageshack.us/img713/2073/ibt.png
You can see that the 2600K scales VERY nicely, almost perfect. You should also not that this benchmark really likes BLCK, as it has a lot to do with how quick the benchmark gets done, that is why clock for clock the i7 930 wins. You should note that as the 2600K at 5.2ghz is a 1000mhz faster than the i7 930 at 4.2, but when you overclock the 930 you increase the BLCK, thus if the 930 was at 5.2ghz with a 21x multiplier, it would most likely beat out the 2600K. Giga FLOP (Floating Point Operation Per Second), means 70 G Flops is 70,000,000,000 operations per second.
Next we are going to use CINEBENCH which gives us an overall estimate of processor computing power, and the result is comparable to other platforms.
http://img143.imageshack.us/img143/4...nebenchcpu.png
The 2600K scores 9.84 Points at 5.2GHz.
http://img135.imageshack.us/img135/9...enchopengl.png
Since the graphics cards were kept consistent throughout the benchmarks, OpenGL difference is made by the processor here. You can see Sandy Bridge really shines.
Now let’s move to ADIA64 Extreme Edition which is like the older benchmarking program Everest. Here the CPU test HASH, FPU Julia, and FPU Mandel are optimized for Sandy Bridge’s AVX instruction that should really take off in the next few years, as it really improves
http://img707.imageshack.us/img707/9669/aidacpuavx.png
Next while we are working with the AIDA64 EE program, I used this program to also do memory benchmarks, here are the memory bandwidth benchmarks:
http://img577.imageshack.us/img577/8...64eememory.png
Now remember that at 2.8 GHz the 2600K is at 1066 MHz memory. I also included 2600K at 2.8 GHz with overclocked memory to show the difference CPU frequency makes to memory bandwidth. As you can see it does improve memory bandwidth some. We are using the i7930 in dual channel configuration, triple channel should do a bit better, but I wanted to compare the systems on an even plane. As you can tell memory bandwidth is an area that Sandy Bridge performs excellent in without a doubt, just look at how even when down clocked it matches the i7930 at 4.2 GHz and 1600MHz.
Here is the last AIDA64 EE benchmark, it is memory latency:
http://img443.imageshack.us/img443/7...orylatency.png
As you can see again, CPU frequency has a great impact on latency with SandyBridge, the fact that I used/set cas 9 even when SPD was lower was so that I could get nice base line readings.
Next we have real world performance benchmarks, First up is WinRAR:
http://img709.imageshack.us/img709/8043/winrars.png
2600K is doing well, not better clock for clock, but its higher stock and overclocked frequency give it a huge edge over i7 930.
Next we have the video encoding program X264, gives us an average FPS.
http://img833.imageshack.us/img833/9917/x264w.png
As you can see the 2600K is faster clock for clock.
Now here are the requested benchmarks, I had two requested, the first one is a Chess Simulator, it is very CPU intensive, and I took a score I think the person was looking for
http://img218.imageshack.us/img218/8797/chessbench.png
Again you can see that the 2600K’s frequency give it an advantage.
Next we have a science benchmark, it is pretty old, but has some nice features, here you go, Science mark:
http://img545.imageshack.us/img545/2624/sciencemark.png
Here you can see that the 2600K clock for clock is a very good contender, this is more of a real life benchmark as is the chess program, as it actually models molecules like the Arena program plays chess.
NF200 SLI and SATA6G Performance
SLI Performance w/ NF200.
Now I should say a little something before I show you results of X58 vs. P67w/nf200. That is that the X58 platform has native support for SLI, it does it naturally. P67 is not meant to replace X58, especially not X58 SLI. P67 natively has 8 lanes of 5GT/S PCI-E 3.0 which goes into 16 lanes of 2.5GT/s PCI-E 2.0 which X58 has 36 lanes of PCI-E 2.0. You can see that P67 is in a huge disadvantage, so motherboard companies have taken it on their own to deliver platforms with the ability for 2-way SLI and 3-way SLI. Now while you can run 8x, 8x SLI, it is slightly better to run with full 16X per lane (not noticeable), and if you want to do 3 Way SLI you have to have at least 24-32 lanes. So the NF200 PCI-E Bridge is added. This bridge takes 16 lanes and turns them into 32. The NF200 is especially good at allocating the lanes correctly, but it has its drawbacks, most of which is its addition of latency to the PCI-E bus.
Theoretically a board with NF200 should perform worse than a board with native 36 lanes of PCI-E. In practice, well let’s see what happens in practice. In theory with just going off what we know SLI with NF200 from 16 lanes of PCI-E should be much worse than true 40 lanes SLI.
SLI Gigabyte GTX 570, two cards, both in 16x slots. Not OCed, at stock.
First let’s take a look at 3DMark Vantage, a very common benchmark used to generate scores that are used to compare systems as well as tell you how well your computer can play games. For this benchmark we used the performance setting. PhysX was left on auto, and it went to GPU, that is why CPU score is so high.
http://img607.imageshack.us/img607/4...ageppuw570.png
At stock and clock for clock the P67A-UD7 bet out the X58A-UD5. It was hard to believe; I had to run everything 5 times, every one of these benchmarks was run 5 times. I couldn’t believe the results, but do not worry it pans out in a little. The margin for the P67A win is extremely small; I would say they are equal.
Now here is the same 3DMark Vantage with PhysX set to CPU.
http://img408.imageshack.us/img408/5...tageppucpu.png
The same thing here, graphics seems to increase with CPU speed, but at clock for clock the P67A-UD7 is faster than the X58A-UD5. But again the margin is a few points, for my standards it has to be 75-100 PTS or above on GPU score for it to be better. I would say that in most cases they are equal.
Now 3DMark 11 is a very new program, and well doesn’t recognize SLI with GTX 570, some of those scores are worse than single card. But never the less I included them because I did all of them.
http://img43.imageshack.us/img43/8633/3dmark11.png
You can see that the X58A-UD5 beats the P67A-UD7, and then ties it later on. Once again doesn’t beat P67A by my standards. I believe that this program likes X58A-UD5 better than P67A-UD7; I can believe it does as well because it doesn’t recognize my processor or SLI on my GPUs. BUT it is a benchmark never the less and has pull. I think we have to wait a few months because this benchmark becomes are legitimate as 3DMark Vantage. Right now we can tell that 3DMark Vantage P67A wins and 3DMark 11 X58A wins, I conclude this by saying they are pretty much equal.
Now let’s shift over to another DX11 benchmark, Unigine Heaven, it is just beautiful the way it benchmarks, actually nice to watch. Futuremark should sit down and watch. The best part is that Unigine is free…. Again Futuremark.
http://img823.imageshack.us/img823/1433/unigenfps.png
Unigine also gives us a score, but I was looking for FPS. You can see they are pretty much on par, also notice that at 4.2 GHz the i7930 ties the stock 2600K. That is a lot of great gaming power the 2600K has.
Now we move onto actual gaming benchmarks, I only did two, the first one is HAWX DX11, and it has its own benchmark program.
http://img221.imageshack.us/img221/245/hawx.png
You can tell that this benchmark is pretty much set on giving you one value, unless you increase GPU performance. (These cards have their chastity belt in tact, later i will have a GTX 570 SLI review, where I break open the belt ). This is a good benchmark for GPU, as it gives a very consistent number, now the scaling got cut off, but the difference is that 2600K max FPS is 65 and 930 stock gives us 63. That is a TWO FPS difference, almost nothing. See that the average FPS did not change, that means that this is almost 100% GPU dependent, as the GPU configuration did not change.
The last SLI benchmark is real world gaming, Call of Duty 4: Modern Warfare. This benchmark was done using fraps, on record for 5 minutes and then spit out an average FPS, min, and max. I start recording on the first level of the first mission. I did this test the most because I actually enjoyed playing the game (I never play games), so the results have been averaged, 5-6 runs for each CPU setting.

SATA6G performance:
Now up until now there were only really a few options if you had an SATA6G capable SSD. But the only SATA6G capable SSD to date is the Crucial C300, luckily for you guys I have one, and have done a comparison of the old Marvell SE9128 which was the best SATA6G controller until now that Intel integrated SATA6G into the PCH. There were a few problems with the Marvell controller, and they lied within early firmware releases, 4Kb Random data speeds were slower than they were on ICH10R (Intel SATA3G). Throughout this past year GIGABYTE worked hand in hand with Marvell to work on the firmware for the Marvell SE9128, through the past 6 months there has been a huge jump in overall performance of the controller on my X58A-UD5. Well those updates where right on time, as Intel’s SATA6G does live up to all its glory. Right now, only Intel RST 10 drivers will work for this, or else you are stuck with MSAHCI.sys which is Windows stock driver for AHCI enabled drives.
Here are side by side pictures of Marvell SE9128 with latest updated firmware VS Intel PCH67
Marvell on the Left with MSAHCI.sys, and P67 on the right with iaStor driver
http://img214.imageshack.us/img214/6...omparision.png
Now as you can see the results are pretty close, if you know a lot about SSDs you know you are looking at a 20% increase on OS performance. How you ask? Well you see where it says seq, that stands for sequential, that means large files, when you use an OS, sequential comes in play when loading the OS, games, or other very large files. Yes this drive only breaks SATA3G border on sequential, but that is not why people buy this drive(well yea its why some do), people buy this drive for its fast 4Kb speeds(4K). That is the file size most used in random windows OS performance. Such as opening a program, using a word processor, loading the internet and browsing web pages. General OS performance is about 90% 4K speeds.
Hard drives don’t touch 20mb/s, let alone 10mb/s. This is what makes SSDs fast. A Sandforce drive can do about 20-25mb/s, and a C300 can do 25-32mb/s. ASSSD is very hard to get a score on the high side of a the secturm, but what you are looking at is the 4K performance of ICH10R on PCH P67. in another program like crystal disk the scores would be higher, 4k read would be able 30mb/s. The reason I am only using AS-SSD is because of its consistency over Crystal Disk. Look at the jump in 4K writes, that is impressive too. Intel finnaly did it, they gave us a perfect SATA6G controller. If you guys want more benchmarks on SATA6G just let me know.
ASSSD is a program built for SSDs unlike hdtun and hdtach and atto.
GIGABYTE Programs and Conclusion
GIGABYTE Programs
Gigabyte packages many interesting programs, in my In-Depth preview of the board, I took a look at Smart 6 and its ability to store your passwords in the BIOS and Backup BIOS. Now I am going to take a look at the new EasyTune6 (ET6) and Dynamic Energy Saver 2(DES2).
Easy Tune 6: Now there is not much change from versions of this program for other boards, but the things that have changed are worth noting. First off, easy overclock options, allow you to OC automatically to 4.1ghz.

Quick boost is a very nice option, but as I stated in my OC Guide you can most likley OC to 4.5ghz without having to mess with anything but the cpu multiplier.
If you are going to more Extreme overclocks, this next image might be useful. Here are the OC options for in-windows OC through easytune.

EasyTune6 also has a new layout for temperature and fan monitoring, it draws nice graphs for you for your voltages:

Now moving on, EasyTune also allows you to OC your GPU:

Lastly we have Dynamic Energy Saver. This litte program is powered by the Intersil PWM, and you can see all 24 phases/”engine cylinders” in action if DES2 is turned on. Now you might be wondering why all those lights on the board went off when Windows Loaded, that is because they are all software controlled. This program will allow yout o turn those lights back on, and seeing the phase LEDs work is pretty cool. This board also has ACPI power state LEDs, they can be turned off in BIOS if needed.

DES2 allows you to see how much power your system is drawing, now I don’t know how accurate it is, but I bet it shows CPU power draw pretty well as it is run by the PWM that controls the power output to the CPU.
Conclusion:
I sum performance up into five categories: Performance, Functionality, Overclocking, Value, and Appeal.
I once had a professor back in college, and he gave us a written exam, I aced everything on it I mean aced it. Well when I got my grade back he had given me a 90%, and when I confronted him he gave me such a crazy answer I just accepted it and took my A. He said, "Yes you got everything right, but 100% is for God, 95% is for me, and 90% is for you." What a nut, but I am not too far off, so no 10 point out of 10 for any manufacturer, because in reality, nothing is perfect.
Scale of 1-10, I don’t give 10s.
Performance:
Motherboard and Processor performance is excellent, that is all I have to say. Yes the increase frequency is what makes the processor very good, but also the fact that it operates at those high frequencies at stock is impressive, and the fact that the motherboard can take it there is just great. SLI performance is much better than expected. With two cards this puppy is as fast if not the smallest bit faster than X58 SLI, I believe this is because of the PCI-E controller built into the CPU is much better than that of the X58 IOH. Although it has less PCI-E lanes, it seems to really boast some amazing performance. Even with the latency increase from the NF200 it still matches X58. I would say that SLI performance is equal and that is much better than expected, because P55 SLI was really not equal to X58 SLI performance. Intel’s PCH P67 really has a very nice SATA6GB/s controller that delivers exactly what people want, excellent SATA6GB/s performance. GIGABYTE has worked closely with Marvell, and even peripheral on-chip SATA6G is impressive compared to on-die. In terms of Turbo mode there is absolutely no lag from multiplier to multiplier that people have been complaining about on other boards. With this board you don’t even have to use turbo, and the multiplier apparently stays fixed at what you set. Max stable BLCK I reached was 107.5MHz. Score: 9.9
Functionality:
This board has more connectivity than I have ever seen. It even provides the ability to change SATA internal ports into eSATA, and vice versa. USB 3.0 is all over the place, two internal connectors and many in the back, I have never seen so many SATA ports. Instead of using the LAN connectivity of the PCH P67 GIGABYTE chose to use dual Realtek NICs, so you can team them and use them in parallel or serial. The heatsinks get pretty hot (the NF200 one does) and this is a good thing, as they are actually working. They are also very low profile, and there were no spacing issues. There is however a little spacing issue with RAM problem but it is just a matter of looks, and actually is like that for better performance. Score: 9.7
Overclocking:
This board is just sick, if max BLCK is quality of the board then this board is extremely high quality at 107.5, 107.7 set. I was able to take my D1 stepping 2600K to 5.2 GHz, the only problem was the heat from the processor, and well that is the processors problem, these might be lower TDP at stock, but OCed they really know how to release heat. 5.1 GHz is my 24/7 OC and that is more than enough. At a minimum auto OC of 4.5GHz you will have a really hard time finding any system that OCs that well. I was able to just walk up the multiplier to 5 GHz and the VID slowly increased. This proper implementation of SVID is just AMAZING. On what other system can you auto overclock like that? X58 systems will just over-volt, might even damage your processor too, so only try this on P67 with a K series processor. This board has CPU PLL Overvoltage option which only works for D2 stepping chips, but that is an option every Overclocking board should have. I have to give this board a 9.9 as it took my processor to its limits; I wish I had a D2 stepping so I could go for 5.5 GHz! Score: 9.9
Value:
This board has a pretty hefty Retail price of $329, but if does have an NF200 chip which is what you are really paying for. If you do not plan on SLI there is really not much of a reason to buy this board other than the power phases and features. I feel as if you have dual video cards, and a hefty PSU to power them, then $329 for a board is not that much to pay. Considering this is a mainstream product, that price is a bit high. You are paying for very high quality components; it’s hard to find any board better built. The fact that Gigabyte manufacturers their own boards is a great thing, they are one of the last of a dying breed of motherboard makers. The UD4 costs $199 and the UD5 $269 respectively. Score: 9.5
Appeal:
This board is such a great change from the baby blue color of X58 and previous Gigabyte boards. I really like it, as do many people I know. One thing that is one of my pet peeves is that many black PCB boards look brown up-close, such as my P6X58D-Premium. It’s because of the copper of the traces and PCB that bleed through. With My P67A-UD7 there was none of that. This board is really black, and matches my GTX 570 SLI and Dominator RAM very nicely. I think GIGABYTE actually used an extra layer of black matte PCB to cover up those traces without bleed through. The Gold accents on the new heatsinks is very nice, they really did a great job with the looks of this board. Right now this board doesn’t have a UEFI BIOS, which many users want. But the fact is you don’t really use your BIOS much, it’s not an OS. You use it to Overclock, and the truth is a traditional style BIOS is much better for overclocking in my opinion it easier to use a keyboard. Because of lack of UEFI I have to take of a fraction of a point, but the hardware is there so it will be implemented shortly. I should mention you CAN boot from 3TB+ HDDs.
Score: 9.7
Total Score: 9.75, this board is Excellent in all areas. It doesn’t fail to exceed all my expectations.
Pros:
High Overclock Ability
VRD 12 Certified (Very good SVID implementation)
Excellent SLI performance
Excellent SATA6G and USB3 connectivity
Very stable board
Nice board and heatsink color scheme
Cons:
UEFI not implemented yet (for most of you, I prefer no UEFI as I feel it just isn’t stable enough yet)
No IDE (overclockers like IDE)
PCI-E 1x slot is blocked by NF200 Heatsink
I would like to thank everyone at GIGABYTE for making this review happen!!! Without you guys we wouldn't have this amazing board!
