Z87-G45 CPU Power savings options

Greetings,
What Power Savings options does this motherboard has, and where can I find them? I'm looking for stuff such as  ERP, C1E and EIST (Enhanced Intel Speedstep Technology).

In bios click OC (overclocking menu) after that scroll to the bottom and click on CPU FEATURES there you have what you ask for. Goodluck

  • Z87-G45 CPU Fan Sensor Malfunction

    Seems like pretty much a non issue but none the less I want to figure this out. When monitoring fan speeds on the MSI Z87-G45 Gaming motherboard it keeps reading zero, then returns to a normal level, then reads 0. I noted this even in the motherboards on utility accessed before allowing windows to load and again using a 3rd party monitoring program. I'm going to assume its a faulty sensor but I'm just not sure. Anyone have any ideas?

    the stock coolers with Processors suck and are only meant as basic cooling (if there under load they get very hot and the fan spins at 100% which on them sounds like a jet engine) i too would change that for a good after-market one!
    My I5-4590 hovers around 30C idle, and stays under 60C under gaming loads with the stock cooler ... even with more CPU intensive games, so, they do work well if everything is working correctly..... possible that his CPU fan is getting ready to fail.

  • Z77a-g45 cpu power question

    I am having some issues with my 2500k throttling down to 3.3 when the cpu package exceeds 145-150w. My temps are fine and from the testing I have done I believe it might be a motherboard or bios limit. Right now I am running a 4.7 turbo overclock and the voltage is only hitting 1.308-1.312 on average under load and the only things that cause the issue is ibt and aida fpu only stress test. Under full load gaming and benching about the highest I've seen it hit is 110w and have not noticed any lag or slowdown (hwinfo tracking) even in bf3 multiplayer. Pretty much wondering if I have missed a setting somewhere that is limiting the watts or if it is because it's an ivy bridge board with a sandy processor. I have been able to 3d bench all the way up to 5150 but as soon as you start ibt the system powers off, I believe to protect itself from the watts being drawn by the cpu at those speeds.
    Thanks in advance

    I have settled in on a 4.5 turbo overclock and got it tuned in to where I have no throttle  . There really isn't enough performance improvement to run it any higher with this board. I really think I got a nice chip here though so maybe when I can afford it I'll grab a better board. I actually got 4.8 stable with turbo but not worth the temps and voltage needed. Got easier figuring this board out after I knew what the limits were, I really thought it would handle 180w-200w. I'll toss up the bios screens for you in a little while, alot different than what I expected but controls the throttling and makes sure the board doesn't get overheated and throttle. I tossed a fan in on the vrm's to try and keep them cooler too. Running ibt on max might still cause some throttling but I don't think it is worth running on this board because of the power limit.

  • Disabling "CPU Power Management" through BIOS -- any bad consequences?

    Ok, so my new T440S is emitting a most annoying high-pitched noise. After doing some research, I come to the conclusion that it is the so called CPU Whine.
    According to the diagnostics provided on this page:
    http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T510-T410-W510-ThinkPad-high-pitched-whine/...
    Disabling CPU Power Management may silence the noise - as a diagnotic measure, not a solution (as the post asks the user to contact Lenovo support for assistance).
    So I tried that and indeed it silences the annoying whine. I have already contacted Lenovo and they said they will get back to me after Christmas. Meanwhille, I am still using this computer, and I am keeping the setting for CPU Power Management Disabled, until Lenovo solves the noise problem.
    I was wondering if this (keeping the CPU Power Management disabled) may have some bad consequences - like melting some parts down or something. Would anyone know?
    Thanks!

    Hi yinslaptop!
    I have good news. I have the same problem. My T440s is completely quiet at 43 °C CPU so I don't need any fans to spin. However there is a slight buzz coming out of the middle of the laptop. And it isn't coming from the speakers nor the fan. I didn't bother to open it up yet and check what is causing that noise, but I guess it's related to some coil whine or voltage leakage. As in your case, when I turn off the CPU Power Management option in the BIOS, the sound dissapears completely.
    HOWEVER I conicidentally put one SD Card Adapter into the Card Slot and the sound completely dissapeared. I would say give it a try. Sadly the sound comes back in 20 seconds at my machine, but I am using a Sd card adapter with no card in there. Maybe this will change when I put one in. Have to test, because I don't have one lying around.
    Lenovo has done a great job. You could to better at this price range, especially when the pc market is shrinking .. it's survival of the fittest. You will see what I mean when you won't get foothold in US and Europe anymore and only will supply Asia.
    You won't probably answer this thread and when you do "awww yes, we are deeply sorry, some level buzz is completely normal" CTRL+V bull**bleep**.
    Don't get me wrong. I really like the new T440s as my first ThinkPad, but my high order of quality wasn't meet. However I still bought it, because I needed one laptop with really good battery life, good screen and small footprint. Well sorry for the rant.

    It looks like a PSU/grounding issue.
    You might need to rebuild the entire PC.
    Remove everything from the case and start with a minimal config (barebone).

  • Msi z87 g45 power cycling

    I recently built a new pc in November and haven't had a problem with it until now. It doesn't post doesn't beep and won't boot as well. No display and it does this very thing with nothing plugged in at all (obviously the psu is plugged in).
    My specs:
    Msi z87 g45 gaming
    I5-4670k (not over clocked yet)
    Gtx 660
    Corsair vengeance  2x4 gb ram
    60 gb  Kingston SSD
    Evga supernova nex750b psu
    The problem started yesterday when I had removed all of my components to route my psu cables.
    After getting everything installed correctly I plugged it in and hit the power button and it came on for a second and turned back off I thought I had forgotten to plug the 8 pin cpu power in until it turned on a second later and immediately turn off. I quickly killed the power and had a look inside but nothing appeared to be wrong.
    Now every time I turn it on it sits there turning on and off until I unplug it.
    I've tried switching the ram the psu and reseating the cpu several times and nothing works.
    I did manage to get it to stay on by shorting a jumper labeled "J1" but  there's no display or anything other then the fans and LEDs being on.
    Anyone know what could cause this? Everything is brand new  and  has only been running for a month and was running two days ago.

    I have tried clearing CMOS by the button the battery and the jumper.
    The only bios setting that I changed was to set my ram to run at 1600mhz which is what it's rated for (it was running at 1333 on the auto setting)
    The thing that puzzles me is that J1 jumper that is right next to dim 1.
    If I hold a screwdriver to it during the power cycling thing it stays on as long as it's being shorted but I don't get a display or anything everything is on and spinning but it doesn't boot. As soon as I take it off it reverts back to the cycle of on and off.
    I've searched google for any possible incompatibilities or fixes but I couldn't find any.
    Also something I forgot, I accidentally bent one of my usb 3.0 pins to the point where it touched another pin. Could this have caused my problem? If so rma wouldn't work cause I bent a pin. I'm totally fine with buying a new board but I'm not sure if it's the board or some other component.

  • Z87-G45 has High CPU Usage from "System Interrupts" from USB EHCI#2

    After install of Z87-G45 Board and associated drivers the CPU was being consumed by high System Interrupts.  I finally tracked this down to the device named Intel(R) Series/C220 Series USB EHCI#2 - 8C2D device.  When I disable this in device manager the high cpu immediately drops to 0.1% or less and when I reenable it the CPU consumption goes back to 50% of one core of an i5-4670K under Windows 7 64-bit  Of course disabling it turns off most of the USB 2.0 ports.
    I have unplugged all USB2.0 headers from the board, updated bios to 1.5, updated the device driver from 9.4.0.1017 to 9.4.0.1025 (7/31/2013), installed the new Intel ME 90 driver pack released  on 10/29 and none of this has helped.
    Is this a faulty board or is there something else to try?

    It was a motherboard swap not a fresh install.
    Hopefully you don't have any other problems. This is the recommended way to go.
    Quote
    Problem solved.  For the benefit of others who may run into this kind of problem here is my solution.  Look for articles on "remove unused USB devices" as a guide.  You will be surprised how much junk is left installed on your system.  Anything ever plugged in will leave garbage behind. 
    Go to control panel->System->Advanced system settings on left then under Advanced pick Environment Variables at the bottom.
    Create a new variable name = devmgr_show_nonpresent_devices and value = 1
    logout/reboot
    go to device manager and under view menu pick show hidden devices.
    Now manually go through and remove all the grayed out devices, especially under the USB controllers section but worthwhile to remove all the old garbage.  Reboot when done.
    As always make backups before you start.
    Good work

  • Problem regarding Z87-G45 and graphics card

    Hey guys, I upgraded my PC yesterday and only kept the graphics card from my old one because it was pretty decent. PC now looks like this:
    MB: MSI Z87-G45 Gaming
    CPU: i7 - 4770K
    RAM: Corsair Vengeance 1600 Mhz (2x8GB)
    PSU: bequiet! Straight Power E9 600W
    and my trusty ASUS Geforce GTX 660 Ti
    So basically I installed a copy of Windows 7 on my new SSD, installed the Drivers that came with the MB, and proceeded to download the new nvidia drivers because my graphics card was only being recognized as "standard vga video card". When I rebooted the system my PC froze at the Windows Logo and then rebooted itself over and over, getting stuck at the windows logo. Some times I got onto the desktop, could even open my browser etc. but that only lasted for a couple of seconds. Safe Mode was working fine though and it recognized the card and drivers. So I googled a bit, tried the card in my old PC and it was working fine.I tried my old GTX 260 but that gave my screen a very red-ish tone. Then I set up Windows again and installed every single chipset driver and MB driver, using mainly the MSI Live Update without my card in the system. It's running on the CPU's GPU atm. Then I plugged in my 660 Ti and didn't even get sth on screen this time. Now I've unplugged it again and am using the CPU graphic engine.
    I'm kinda lost by now, I really don't know what else to try and I haven't found a solution I haven't tried on google.
    So I wanted to try my luck with you guys: Am I doing something wrong? Am I missing some distinct BIOS features? Or is my MB/graphics card dying on me? And out of those options, which is the most likely?
    Anyways, any help is much appreciated.

    Well, I tried my luck once again - didn't work out too well. At least I know it can't be the graphics card 'cause that one is working fine here on my old PC.
    But thenagain "compatibility" is a thing.
    Any Samsung SSD's dont have SandForce, that i know of 
    Dosent your BIOS have update software in it? .. that what i used on main (MSI Z87-GD65 Gaming)  and will use in dase on foward when i have it as i dont trust OS's.
    What happend ? ...well youl luck run out but how?
    Did you try different GPU drivers and they did disable your screen?
    You see BIOS but not OS or what? ...
    Edit: if that so then try other storage then your SSD for the os. just to get it out of picture...
    You dont need to "validate" it for test so dont!!!! just set it to get validation later via manual or what ever els it says.
    Edit 2: What if you brack the BD cake and insert that VGA to secend PCI-e x16 slot?
    Edit 3: Samsung 840 have new FW too. So see if yours have one.
    ... i need to update one of my "non Pro Samsung 840" to be present in system, that had other drives in RAID...

  • Help! Can't overclock new Z87-G45 Gaming without Event 41 Task 63 shutdowns

    I'm running into a frustrating problem with Event 41 Task 63 "unexpected shutdowns" when I'm trying to overclock the computer I recently built. The machine shuts down instantly and seemingly randomly under light load, often when it's idle. It doesn't BSOD, there's no crash dump, and the bug check codes are all zeros in event viewer. It doesn't shutdown while stress testing or playing games. It's certainly not overheating.
     If I run the processor at default clock this doesn't happen, or at least, it hasn't so far. But when I dial in a modest 4.2ghz overclock, it'll reliably happen once or twice daily. The thing is, my overclock will stress test for 24 hours stable with every program I've tried (Intel Extreme Tuning Utility, AIDA64, Prime95) and passes Intel Burn Test 10 passes at very high. It only seems to generate the Event 41 errors while idle or web browsing.
     Steps I've taken so far that have not solved the problem:
     - replaced PSU
     - replaced memory
     - checked cable connections to motherboard
     - flashed bios to latest
     - updated all drivers to latest
     - disabled C-states
     - disabled adaptive voltage and dynamic multiplier
     - disabled sleep in Windows power plan
     - disabled all but one audio driver
     - verified hard drive passes dskchk
     - verified memory passes memtest 12 hours
     - verified sfc/scannow gives no errors
     I'm close to abandoning overclocking but that's disappointing.
     Here are my system specs:
     OS: Windows 8
     Motherboard: MSI Z87-G45 gaming
     Processor: Intel i5 4670k
     Cooler: Hyper 212+
     Memory: Gskill 2x4GB 1600mhz 8-8-8-24 (Haswell compatible)
     Video card: MSI 770 GTX Twin Frozer
     PSU: Seasonic G-series 650W (Haswell compatible)
     Firewire Card: SIIG 2-port PCIe
     Drive: Seagate Barracuda 1TB
     Optical: ASUS DRW-24B1ST
     Here's the overclock I've been attempting:
     Core multiplier: 42
     Vcore: 1.16v
     Ring multiplier: 41
     Vrin: 1.15v
     Vccin: 1.85v
     XMP enabled (1600mhz, 1.5v)
     (all other settings default in MSI bios)
    Can anyone suggest to me what might be going on here?
    I've tried raising vcore to 1.19 and running fixed voltage with no difference.
    Are there other settings I should try changing? One thing, for example, is that I've left vdroop control on auto. I have different % options in the MSI bios, should I start experimenting? I read that Haswell has little vdroop so I didn't mess with it.
    Is it right to assume this isn't a motherboard problem, since I don't seem to get the unexpected shutdowns when I'm running stock clocks? I think I've ruled out the PSU and ram since I've replaced them both, so if it's a hardware issue I think it's got to be the motherboard.
    Thanks for any help.

    I know this topic is old but i have been having this same problem as andy and i cant figure it out. Also im sorry if i wasnt suppose to continue on someones thread but i thought it would be easier since we had the same problem. I have the same mobo and cpu, this only happens when i try to OC. when i set it back to stock bios it doesnt happen. Event id 41 with a random reboot and no BSOD. i dont know what to do anymore besides revert back to stock. IF anyone can help me let me know.
    i have oc to 4.4 multiplier with 34x uncore ratio.
    things i have tried. set everything to auto except those two settings above.
    changed oc multiplier to fixed/dynamic.
    turned off xmp lowered ram to 1333mhz ddr3
    tested vcore from 1.15 to 1.265 in bios.
    vccin at 1.9 to 1.95
    vring to 1.15
    auto offset settings (vcore/vrin) - also tried .001 offset as well
    turned off and on c-states
    C1E off
    ram timing and volts to auto or manual timings of 9-10-9-28-2 1.5V which were found on the box of ram
    ive ran memtest+86 for 4 runs with no problems
    sfc/scannow -checked out ok
    ran antivirus/malware
    ccleaner
    lowered cpu multiplier to x40
    i passed AIDA64 and prime95 with 6 hours each with vcore at 1.2 but its reboots randomly when on light load like internet browsing.

  • Z87-G45 usb issues

    I'm having a heck of a time with this board and if I can't get this taken care of today I'll have to RMA it. I'm having many problems with the usb ports. After loading windows and installing the drivers off of the disc, none of my flash drives would work. I received the popular "unknown device" which I could not fix. So I re-installed windows. I tried installing the drivers from MSI's site, but after installing them one by one my keyboard and mouse randomly stop working. If I load in safe mode they do work. Also, not once has any of my flash drives been recognized.
    Is there any hope for me, or is RMA the best option?

  • Z87-G45 overclock not adjusting ratio

    I have the Z87-G45 mobo with an i5 4670k
    I finally got around to setting my overclock on my board. It runs stably for at least 2 hours on Prime95 @ 4.4 ghz w/ 1.210v.
    Now, even though my PC runs fantastically at full load, it's at idle when it just dies. I don't get BSOD or freeze, PC just reboots and tells me OC settings have failed. Now I know that my overclock is fine. After some digging around, I notice that my multiplier seems to be locked at 44 (base clock 100mhz) but the voltages still fluctuate. So my CPU seems to be running at 4.4 around the clock despite having adaptive mode selected in BIOS. I don't have an option to even turn off EIST with an overclock on this board.
     I loaded default settings with EIST enabled at 3.4 ghz and watched the multiplier properly working using the program CPU-z. So multiplier does seem to be working, just not when I'm overclocking.
    What am I missing here? Why won't the multiplier work when I'm overclocking? I have EIST enabled, and have only adjusted the CPU ratio, ring ratio, CPU core voltage, and ring voltage. I've also adjusted the fan speeds for temps but other than that I've touched nothing else. What am I missing?
    Thank you in advance!

    Thanks for the quick reply and suggestions. I did already have those settings tweaked and was still having issues. 
    For posterity, after hours of tweaking every possible thing in BIOS, I found the answer. It wasn't even in BIOS. In control panel > power options, under advanced, there was a processor power management setting that locked the minimum value to 100%. Lowered that down to 40% and voila, working multiplier. I have NO idea why it was still working under default values in BIOS as I haven't touched the Windows power settings since I installed windows. But hey it's working now and as of yet, I have no crashes while my system is in idle.
    Hours in BIOS and I didn't even have to leave Windows to fix the problem.

  • MSI Z87-G45 Gaming, sound from USB mouse?

    Hi!
    I have some issue from my new computer, see spec below.
    For the information I have a MSI Z87-G45 motherboard.
    I have some sound that occurs sometimes (specially during the first 2-5 minutes) when i move the mouse around.
    It occurs as well sometimes when I been using the computer for a while, basically random just more frequently at the start-up.
    It's hard to know from where the sound occurs, could be PSU but today I read something on another forum about the motherboard I'm using:
    - Higher sound quality using USB, thanks to special adapted current power.
    So i wounder if this can be the case? Is that the reason why i get this noise from inside the computer?
    Is there some way to disabled this "feature" in BIOS?
    Greetings

    The sound sounds like the old mechanics hdd kinda.
    It comes inside the computer, not the speakers.
    My feelings is that it can be the PSU as well, just wanted to check this first, since it most often comes when i move my mouse.

  • Z87-G45 Gaming not able to install Win7 x64 with Samsung 840 EVO

    I have a brand new:
    i5 4570
    MSI Z87-G45 Gaming
    250GB Samsung 840 EVO
    1x 8GB Corsair ValueRam DDR3 1600
    I got everything hooked up properly, but I am not able to install Win7 x64 through an USB pen drive (Kingston Datatravel 32GB USB3) I have a proper  official and Legit MSDN ISO, formatted by the Win7 USB tool from MS itself.
    Note that i do not have an optical device (DVD) installed so I cannot use it 'the old way'.
    Bios settings are okay, everything is recognized
    USB Legacy - Kingston Datatraveler
    HDD Legacy - Samsung 840 EVO
    Win7 setup loads properly; but before I can select the Harddrive / SSD to install Win7 on I get prompted that additional (3rd party) drivers are needed to proceed. The volume is not recognized. This happens 9 out of 10 times. In the 10% cases I do get the option to format the SSD and/or create partitions. However, installation fails after all, cannot load or find file ...
    What I've tried so far:
    Switch out the SATA cables and power cables
    Switch through the various SATA ports on the MB 1 through 6
    Tried UEFI and UEFI/Legacy (UEFI doesn't seem to work at all)
    Update UEFI to V 1.50
    All the above result in the case mentioned.
    I have succesfully installed the SSD in an other PC, using the same pen drive and ISO and it worked like a charme, thus ruling out that the SSD, pen drive or image is corrupt.
    Even when I switched out the SSD after Win7 setup has succesfully copied, unpacked and installed all the files (doing this on the other machine where it works like a charm). Then switching it to the MSI Z87...it fails; starting the setup procedure right from the start, like nothing was ever written on the SSD...
    Finally i turned to Win8, and guess what, it installed without any glitches on the MSI Z87
    What am I missing here, I would really want to install Win7 instead of Win8
    Forgot to enable / disable something in the UEFI? I really don't know, google doesn't give much information on this specific problem (SSD is recognized properly by the BIOS / UEFI as far as I can tell)
    The only thing I have not tried out so far is updating the Samsung SSD firmware to the 1.0 version which has been release 3 days ago...
    Any clues, tips, hunches??

    Quote from: Bernhard on 25-October-13, 18:33:41
    Did you disable Secure Boot in the BIOS? If not, then Win7 won't load.
    Hmmm not sure, thanks for the reply, will have to look into that later today!
    I didn't change it from the default setting I think, unless it is part of the Win8 features in the UEFI. All where disabled by default, and I kept them disabled.
    Where is Secure Boot listed in the UEFI, and any idea wether it is enabled by default?
    ::EDIT::
    Found it in some screenshots, I cannot recall from the top of my head wether it was enabled or disabled, allthough my gutt feeling says it already is disabled.

  • MSI Z87 G45 GAMING erratic BSOD/freeze @ 2300, stable @1600. Can't solve.

    Hi All,
    I would welcome some advice. I am about 4 months into a new machine build:
    * MSI Z87 G45 GAMING motherboard
    * i7-4770K Haswell 3.5 GHz & aftermarket heatpipe cooler
    * 4 x 4Gb G.Skill SNIPER DDR3-2133 PC3-1700  (F3-17000CL11D-8GBSR)
    * GeForce GTX 650 Ti  w/ 2 Gb Video RAM
    * Samsung 840 Pro 256 Gb SSD
    * Thermaltake 700W Toughpower
    * Win 7 Pro 64-bit SP1
    The system seems to run fine at the default 1600 MHz RAM speed, however if I implement either of the X.M.P. profiles (which kick the memory speed up to the RAM's advertised  speed of 2133 MHz), the system will occasionally (every 8 to 48 hours) freeze or BSOD.  The BSOD stop codes are inconsistent in number (0x00, 0x41, 0x1E, 0xC4) and driver.  When the system freezes, there is no consistent behavior.  I am not doing any other overclocking besides using the X.M.P. profile in the memory. 
    RAM timing on the 2133 X.M.P. profile is: 11-11-11-30.
    I have updated the BIOS to 1.5, including the ME, and updated all drivers in the system.  All irrelevant hardware and drivers are disabled.  Also I have done the following:
    * MemTest+  5.01 for over 30 hours, all 4 sticks in.  No errors.
    * Intel BurnTest on 'Very High', 10 passes, no errors
    * Prime95 for over day with 90 C CPU temps constantly being hit.  No errors.
    * Unigine Valley Benchmark for 30 minutes; no issues
    I increased V_DRAM from 1.60V (from the XMP profile) to 1.65V, and I also added  +0.10V offset to increase the CPU I/O ANALOG , CPU I/O DIGITAL  and SYSTEM AGENT voltages.  Didn't seem to help.  All other CPU voltages are default from [auto].
    I rolled the memory speed back to the default 1600 MHz, and the system seems stable as a rock.
    I don't really need to have the memory run at 2133 MHz, but it irks me that the system is not stable with the rated components, and I'm befuddled why the stress tests seem to pass just fine, then the system will randomly hang with arguably a far less demanding load than the stress tests.
    Note that I have not yet:
    * reset the CMOS when changing to X.M.P.  Perhaps I should?
    * reseated the graphics card or CPU.  The latter will require R/R of the thermal grease, which I will do if needed, but it's a pain.  Since the system is stable at 1600 MHz, I assumed that all basic systems are working as they should.
    * Tried to work my way up in memory speed step by stem from 1600 to 2133 to see where things fall apart.
    * Tested the video memory
    I suspect main system memory, despite the clean bill of health from MemTest, and based on many of the comments to others with similar problems from the veterans on this board.   I don't want to push the CPU voltages too much above the default/auto values, for fear of damage and reduced lifetime.
    Also, the power supply is a nice unit from an older high-end gaming rig. It is rated at 700W.  The PS does probably have over 30,000 hours on it (24/7 use for 3-4 years), however.  Strange that it would work at 1600 MHz fine, and with only slightly more power load at 2133.  I suppose stranger things have happened. 
    I've read the suggestions to run only 2 sticks, rather than 4, but I can't justify dropping $140 on new memory (I don't really need the extra speed benefit, it's more curiosity and just not knowing at this point).
    Anyway, perhaps more seasoned souls than I can share their thoughts.  The system is perfectly usable at 1600, but I'd really like to know where the lockups are stemming from.  Troubleshooting is maddening because of the inconsistency in the long times before failure and lack of repeatability to reproduce the issue.
    Thanks in advance for your time.

    Thank you both for the prompt replies.  I'm learning a lot.
    Turns out I also found this from G.SKILL in going over reviews of the memory modules I have.  Another user had a similar configuration as mine and was having similar problems.  G.SKILL replied:

    We are sorry to hear you were unable to get two kits working in the same system. It is not guaranteed two kits can operate at the rated specifications since they were not pre-matched, tested, and guaranteed at factory. With multi-channel motherboards, perfectly matching memory is necessary to achieve high frequency. This is why we must offer high capacity 32GB, 64GB kits, otherwise we can just sell one module at a time and have you purchase as many as you need. Unfortunately, memory does not work that way. If you purchase a 16GB kit rated at DDR3-2133, you should have absolutely no issues. For any further questions or concerns, please feel free to contact us directly for assistance.
    Thank you

    Not knowing any better, I simply purchased two "kits" of 2x4 GB each and installed them.  Perhaps worse, if the modules were matched, I may well have mixed them up so the matched modules don't even sit in the same channels 1/3 or 2/4.  G.SKILL seems to have a pretty responsive board, so I'll ask them what they suggest.
    Also in the end, I really just want a stable machine. This is a basically an office/engineering machine.  My initial thinking was that if the system was unstable at 2133 then there is something wrong with it that needs to be fixed.  It sounds instead like getting to 2133 is not guaranteed, and is much more of an art than simply throwing the modules in and powering up the system.
    I'm perfectly happy at 1600 knowing the system is stable.  Indeed realizing now that 2133 requires overclocking, I may well have backed off to 1600 even if everything had worked just fine at 2300, just to trade extra stability for the (small) performance improvement that I would likely never notice anyway.
    I'll put together a post for the G.SKILL forums, and if I get anything useful I'll post what I learn here for completeness. 
    Thanks again for the fast and informative replies.  It's much appreciated.
    Best,
