Z77A-G45 System Instability

Motherboard: MSI Z77A-G45 (BIOS Version E7752IMS V2.4 - I did not update the BIOS, it shipped this way)
CPU: Intel Core i7-2700K Sandy Bridge
PSU: CORSAIR HX850 850W
RAM: G.SKILL Ripjaws X Series 16GB (4 x 4GB) 240-Pin SDRAM DDR3 1600 (PC3 12800) Model F3-12800CL9Q-16GBXL
Case: Antec Three Hundred Illusion Black Steel ATX Mid Tower
HDD: 1TB Western Digital Caviar Black WD1002FAEX (SATA Port 2)
Optical: ASUS 24X DVD Burner DRW-24B1ST/BLK/B/AS (SATA Port 3)
GPU: EVGA 012-P3-1570-AR GeForce GTX 570 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16
OS: Windows 7 Ultimate 64-bit
Main Problem: System Instability. I've managed to get the OS installed, and was able to eventually get VirusScan, Windows Updates, Chipset drivers, and other drivers installed. However, this was a painful process, with several BSOD's, program crashes, and other lock-ups. After doing so, the system is still unstable.
I also have an SSD I intend to use for acceleration via Intel Rapid Storage Technology (RST). I plan to eventually plug this into SATA Port 1. But I didn't get that far...
I am not OC'ing - using Standard Mode. The only change I made in the BIOS was to switch the SATA Mode to "RAID Mode". I did this prior to OS installation, per instructions. And during OS install, I loaded the Intel SATA controller, per instructions.
OS install was unusually rocky. First attempt failed. Second attempt worked, but took longer than it should have. After installation... crashing, instability, and BSODs.
Checked Memory a couple times, via Microsoft's memory checking tools. Also reseated all DIMMs, to no avail.
After some amount of troubleshooting, I saw that my memory was being reported as: F3-12800CL9-4GBXL DIMMs. I assume this is correct, and that the "Model" I bought (F3-12800CL9Q-16GBXL) just describes the whole package of 4 DIMMs. However, the one thing that is incorrect is that the timing is reported in the BIOS as 11-11-11-28. The timing specs on my RAM are 9-9-9-24. Overriding this in the BIOS to those numbers (for TCL, tRCD, tRP, tRAS) did not make any difference. Instability continued. The memory speed and voltage seems to have been set properly to 1600/1.5V.
The other thing to note here is that I just bought the MSI Z77A-G45 to replace an ASUS P8Z68 DELUXE/GEN3, which was experiencing the same (but less frequent) instability. I've been using it for a couple months, and decided to try my luck with a different motherboard. Only this one is worse. The only components that were reused were the CPU and RAM (and optical drive, PSU, and Case, if that matters), and the only other thing in common was that I had both set up in RAID Mode.
Thoughts on how I should proceed?
Thanks in advance,
-Todd

Regarding the memory speed, I'm confused. The maufacturer site (gskill.com/products.php?index=349) says:
CAS Latency 9-9-9-24-2N
Speed DDR3-1600 (PC3 12800)
Also just to confirm, to change the timing, I assume I change this in the BIOS, under DRAM Timing Mode, switch to "Link" (from "Auto"), correct? And when I do this, it enables the "Advanced DRAM Configuration" section. If I double-click that, I can specify 9-9-9-24 (for tCL-tRCD-tRP-tRAS). Former values were 11-11-11-28. I assume I leave all other fields at "Auto"? What is the "-2N" in the CAS Latency description on the GSkill site?
Here is the reason:
They are real DDR3-1600, but that means CAS = 11 @ 1.5V
Their XMP profile is buggy (in fact that's the DDR3-1333 profile).
For 1600MHz with CAS = 9, they need 1.60-1.65V

Z77A-G45 start up-shut down loop with more than 1 stick RAM

New Build, personal use and doing it myself:
BOARD: MSI Z77A-G45
BIOS: *?* click-bios reports "E7752IMS V2.5", but "MS-7752 VER: 1.4" printed on board?
PSU: Thermaltake 850-watt Black Widow 69A 12v rail
CPU: Intel Core i7-3770K BX80667i73770K - Quad Core, 8MB L3 Cache, 3.50GHz, 77W, Unlocked, fan included, no extra cooler yet
MEM: Corsair Vengeance CMZ8GX3M2A1600C9B 2x4GB 1600 MHz, 9-9-9-24, PC3-12800, 1.5V
HDD: WD Blue WD10EALX 1TB, SATA 6Gbs, 7200RPM, 32MB Cache
CASE: Thermaltake VN770M1W2N Overseer RX-I Full Tower
OS: Win7 Pro 64-bit
System bought as bundle including the 2x4GB Corsair RAM. Assembly went well but took me a long time to make sure I had it all right. Then, nothing happened at power-up, no lights or anything. My first reaction was to replace the included Thermaltake power supply (700 watt 52A 12volt rail) - I disconnected all power to the unit and removed the original psu and, on a whim, I booted up with the original power supply outside the case and the lights came on with the psu laying on it's side! Got the start-up and shut-down loop (lights up and spins all fans for a few seconds, then shuts down and repeats ad infinitum), which I was not expecting. Replaced the original power supply with the Black Widow (specs listed above) and got same shut-down loop.
Started checking the memory sticks one at a time in DIMM2, each produced that shut-down loop. Also tried with two sticks of Patriot Viper 3 PVI316G160C9K 2x8GB 1600 MHz, 9-9-9-24, PC3-12800, 1.5V (which doesn't appear on MSI's compatible list...but I had it handy) Then, With the last 8GB Patriot stick in DIMM2, I finally let it go through that shut-down loop 5-6 times out of frustration, and then it suddenly powered up "normally"!
I took advantage and have smoothly installed Win7 Pro, and mobo drivers from CD, no glitches, USB working fine. Then tested each stick - all 4 RAM sticks work individually in DIMM2, but the board will not accept a 2nd stick in 4 without that same shut-down loop (tried using either matched pairs). Manual specifies using DIMM2 and 4 (which are the black ones) for dual channel. Have also tried slots 1 and 3 (blue) with same shut-down loop results, no BSOD or error codes, not even any beeps. Computer boots normally and runs Win7 just fine with one 8GB stick in DIMM2. Also boots Windows and runs fine with one 4GB Corair chip in DIMM2.
Have done CMOS clears and also re-seated the cpu and heatsink/fan, and all pins and board connections looked OK.
Have some problem getting into the BIOS screen to look at things - seems to boot up so fast with a re-start that Delete key and F11 don't quite catch before Windows starts (8-year-old Logitech USB keyboard?). Have to completely power down and start up to get into BIOS, but that doesn't always work either. System recognized the memory change to the Corsair stick, but the screen went by so quick I couldn't catch it to get into BIOS.
Questions:
1) I've searched this board and read for hours about similar shut-down loops problems, but either nothing seems to match my particular quandary or I don't know what to look for. I don't understand what's happening with this shut-down loop - since all four sticks work individually in DIMM2, could DIMM4 slot be defective and I need to RMA the board?
2) I have not yet removed the board and tried to start it outside the case - could a short be causing the 2nd slot to malfunction? Standoffs are built into the case but they didn't seem too low, and the amount of standoffs matched the mobo mounting holes wiwth nothing else protruding. It's a really solid board that did not bend when being attached. It's also possible to look down behind the board with the front cover off and see that nothing is touching it. Will breadboard it next, since I have to take it out, anyway.
3) Where exactly is the Bios version printed on the board? Click Bios reports version as 2.5 but appears that 1.4 is marked on the board. Have done no updates of any kind, only thing I did was disable the splash screen so I could see POST (like I could read that fast...!). Do I need to contact MSI to find out what Bios version actually shipped with this board? It's OK if I got an older board with updated BIOS, but it's confusing when something different appears to be printed on board.
Additional info: Phase lights - LED is lit and all lights flashed at boot-up. CPU temp running for three hours idle is steady 37-38C, mainboard system temp 25C. Went with a larger power supply because I intend to use Crossfire and more drives in the near future, but using onboard video for now. System to be used for graphics/video processing with multiple programs running.
I'm currently working from an ASUS M3A78-CM board with AMD Phenom 9650 2.4 GHz. I've never dealt with an MSI or an Intel system before, and the Click-Bios is something new to me. Alas, I'm not an expert, but I've followed the basic steps I knew. What did I do wrong, overlook or just plain don't know? I sure would appreciate another opinion before I give up. I'm amazed at the speed of this motherboard/CPU combo - it's probably more than I need, but I'm intrigued to figure it out.
Looking forward to those opinions,
Jilliebob

Do this, and while it is in the open re-examine your cpu pins w/ a bight light and hd zoom or a magnifying glass.
Thanks, xmad, I'll look at th CPU again tomorrow/next day under the glass when I take the board out. I already checked them under magnification and was leaning toward a funky board, but it never hurts to re-check. Eyesight is not what it used to be, for sure (I miss DOS, if that's a clue...). Don't want to flash the BIOS if not necessary, since it runs Windows fine and everything works except that RAM.
Bernhard, I don't have CPU-Z installed on that machine and don't want to install anything else until it's working normally. I'd never seen Click-Bios before and just need to get over my initial suspicion of something new! Also learn my way around it before I change anything. I'd never encountered a board reporting a bios different than printed on it. I've never messed with manual memory settings or done more overclocking than just a little exploratory and suprisingly successful nudge - if you could point me toward a good basic explaination of all those settings, I could learn from there.
Appreciate your input very much.
Have learned a lot just reading the threads here for the last few days. This is the best forum I've ever encountered. I'll report back - some suggestions in other posts resembling my problem ended with no resolution, and that's a shame because one doesn't know if it worked or not.

Brand-new Z77A G45 not booting

Hello all. Just started putting a new build together the other day, using the Z77A G45. When I went to boot it up for the first time, it gave me the "Military Class III" splash screen, with the prompts to switch to POST, start BIOS setup, etc. However, pressing any of the keys doesn't do anything, and it shuts down after about twenty seconds or so. The CPU phase leds all turn on for a few seconds after it's powered on, but after that only the first one remains lit.
I thought it might be because it wasn't recognizing my USB keyboard, but I had the same problem even when I used the PS/2 converter that came with the keyboard. I tried clearing the CMOS, and it gave me a screen showing that it recognized everything plugged into the board, and prompted me to hit F1 to continue setup, which worked, but from there all I got was a black screen with an "underscore" in the upper left hand corner. Rebooting with only one stick of RAM didn't change the problem, and I've tried all the USB ports, with similar results.
I'm thinking that the problem lies in the CPU being damaged during installation, but there don't seem to be any bent pins.
Here's the build:
CPU - Intel Core i3-3220 3.3GHz Dual-Core
Motherboard - MSI Z77A-G45 ATX LGA1155
Memory - Kingston Blu Red Series 8GB (2 x 4GB) DDR3-1333
Storage - Seagate Barracuda 1TB 3.5" 7200RPM
Video Card - MSI GeForce GTX 650 Ti Boost 2GB
Case - NZXT Tempest 410 ATX Mid Tower
Power Supply - SeaSonic 520W ATX12V / EPS12V
Operating System - Microsoft Windows 7 Home Premium SP1 (OEM) (64-bit)
Monitor - Asus VS238H-P 23.0"
Any help or suggestions would be greatly appreciated.

Try it without any ram, you should get a beep. If not it seems to be RMA time.
This is not true depending on the board and bios version. Not all boards/ bios versions beep at all.

MSI Z77A-G45 and Samsung 840 Series weirdness

Ok so here's the thing
about a week ago i decided that it was time to build a new computer with a Z77A-G45 motherboard
put it together, installed windows 7 64-bit and everything was working just fine - for about 5 days -
but then one morning when i turned on my computer it decided not to boot and just sat there with fans running with an A2 code at the bottom left of the screen
i tried taking out the ram leaving just 1 in and moving it to different slots and trying a different ram block boots thinking it might be faulty ram,
when that didn't work i tried removing the graphics card and boot with just the onboard VGA, reset the CMOS jumper, and even replaced that battery on the motherboard thinking the shop might have shipped an almost dead one, took everything apart and booted it outside the case on a glass surface to make sure it wasn't some sort of short
but the only time it actually wanted to get past the A2 code was when i booted with only 1 of my hard drives, so i started changing my drives around using various combinations of SATA cables and ports (luckily had an extra 5 SATA cables lying around)
eventually i narrowed it down to it wanting to boot with 2 of my 3 drives but the 3rd one (a Samsung 840 series 500 GB SSD, that has no system files or anything fancy other then music, movies and a few games at the moment) getting it stuck on the A2 code
so i set it up as an external USB drive with a SATA/USB converter i had sitting around but then it would get stuck on B4 instead if i booted with the drive connected
however everything would work just fine if i connected the drive after the system had booted up (or even just unplugging and replugging it when it got stuck on the B4)
once back in windows with the drive connected i ran all the diagnostics i could think of but nothing showed anything wrong with it
(and the only thing i had done with the drive before it stopped wanting to boot was to defrag it)
eventually i decided to copy all the files from the drive to a different drive and reformat it as sort of a hail-mary
and to my surprise that actually made it boot up just fine
so i moved it back inside the case as a normal drive just to make sure it would still work (which it did) and then moved all the files back to see if any of them were the culprit - that turned out not to be the case however
it booted up without complaint with all the original files on it
so now my question is why?
what the heck is going on?
did defragging cause some sort of data fault that caused the bios to not be able to read the drive properly or did i just buy a haunted computer?
like i said everything is back in the state it was the day before it didn't want to boot and bios and been defaulted so it's not really an issue at the moment but I'd still like to know what's going on so i can hopefully avoid it in the future
any answers or comments will be appreciated

This is strange
I have Z77A-G43, and have exactly the same problem with one 1GB sata drive, that works just fine in every other PC.
In my case PC run into restart loop, but with same code A2 as yours.
Strangest part was PC was restarting even if I put HDD into PCI Sata/Raid card !?
So I am guessing here its not a hardware problem, but a software (BIOS) problem.
Now whole pc with Z77A-G43 is at Service because of faulty DVI output (not working).
Will try reformating drive, but need first to buy >1gb hdd to backup that one
Drive is currently working just fine in this 10y old MSI PC =.=
It seams they have stopped making things as they used to, this old mb is one durrable dog.
which was the main reason I went to same company when in question was mb...

New z77a G45 Motherboard - computer won't start.

Hi everyone,
I would appreciate some help, if possible.
I've purchased the following:-
1) i7 3770 processor;
2) z77a-g45 motherboard;
Installed them just fine (I think?) - first startup I get a 'CPU has changed, update settings' on the BIOS. However, after this message the system shut down. Now there's a faint smell of ozone in the air, and the system won't power on whatsoever. The motherboard has a handy set of LED's labelled CPU phase. When I hit the power button one lights up... then nothing.
I have done the following:-
1) Checked the PSU on another system - it works perfectly;
2) removed and reinstalled the CPU and cooling fan. Reapplied thermal paste.
3) Run the system using only PSU, CPU and RAM.
None of the above seem to do anything. I get the impression I have, through my carelessness, fried something. Any idea, given the vague description of the above, whether it would be the CPU or the mobo?
The power supply I am using is a CIT ATX 12v 700UB supply.
Any help would be greatly appreciated.

Remove the MB from the case and check if there are more than the required MB mounting standoffs. Ensure that there are only the ones that line up with the MB mounting screw holes on the case backplate and no others that would cause short circuit between case and MB. Also ensure that you have no pinched wires or wires with damaged insulation from the PSU that could be short circuiting.
It's always best to assemble the components out of the case on a sheet of bare cardboard to make sure it all fires up and runs OK before installing it in the case. Do this, retest and let us know how it goes.

Will newest intel drivers work on my Z77A-G45 Mobo

Hi so i seen over at the win 8 forums i go to they have a new intel chipset driver that just came out found over here https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=816&DwnldID=20775&ProductFamily=Software+Products&ProductLine=Chipset+Software&ProductProduct=Intel%C2%AE+Chipset+Software+Installation+Utility&lang=eng was wondering if these newest drivers will work on my MSI Z77A-G45 motherboard figured i would update them to the more curent ones if they would work??.

OK thought so and yeah you are right my system is using that rapid storage driver i went in there and it gives me status of drives and also what drivers version its using so i won't touch it , so should i just remove this intel smart stuff its the latest one it looks like it auto updates itself lol.

Re: Z77A-G45 - No Power

MSI Z77A-G45 Can't maintain overlock

I'm having problems overclocking my system. When I enable OC genie it will run 4.2ghz all day np. Now when I reset default values, turn op the vcore and then adjust my CPU frequency I can achieve 4.5ghz quite easily. Run some benchmarks everything is stable no problem.
Now as soon as I shutdown my PC and start it back up it always fails, tries starting about 3-4 times and then decides the OC failed and then restores default settings.
But even when I only up the frequency a little let's say 3500mhz it still won't boot up after powering down. It seems like something is changed after shutting down and powering it up again.
How come manually it can run high speeds but as soon as I power it down and up it fails?
And how come OC genie can run 4200 and power up just fine.
Even when I mimic all values OC genie uses it still wont power up.
update:
I was a little to fast to say it will work with oC genie all the time. At the moment when I load defaults and then enable OC genie it works fine. But shutdown the machine and then start it again it will also fail with OC genie enabled.
So it won't overlock even 100mhz when shutdown, when booted up and resetted there is no problem and I can stabily run 4500mhz with high load np. What is the difference between a reset and a shutdown and start up??? This makes no sense.
I'm running the latest bios version.

Have you installed all of the drivers? I linked win 7 64-bit make sure to select the right one.
Could you post ss's of your cpuid spd / memory tab & bios settings please?
Edit: Did you make sure the memory is installed in the right dimms for dual channel operation it is dimms 2 & 4 which sometimes throws people off.
Edit 2: Don't do this with an I5 2500k, use the multiplier only to increase speed. That cpu does not like that.
Windows & drivers are not the problem. As long as it boots I get into windows, but it will fail at the POST state. Memory is installed as decribed in the manual in slot 2 & 4.
I made some screenshots:
Between pic 1 and the last I changed dram timing to link, but on auto it will fail the same way. Everything is stock. It doesn't matter what I change as long as I don't change the cpu freq it will boot just fine. But god forbid I overclock 100mhz it will fail. But only after shutting down. Like said before I can turn it all the way up to 4500mhz just fine, just don't shutdown and try to boot it up again.
I also did a CMOS reset, didn't help either.

MSI Z77A-G45 can't install window 7 by raid 0

I have a rig which:
CPU: Core i7 3770k
HDD: Two Western Digital 1 TB 7200
Main: MSI Z77A-G45
Power supply: 700W
Ram: 32GB DDR3 1333 MHz
*** VGA card: MSI Geforce nVidia GTX 660 Ti 3GBDDR5 TF
After configuring BIOS to setup RAID 0, I was trying to install Window 7 on my 1.8TB ( which was summed of two HDD )
But I got a problem about couldn't install the O.S on.
***And about the VGA, whenever I plug it in my mobo, my monitor shows black screen as it doesn't recognize the VGA card. What happen if I install window then add the VGA card later? Will it affect on my system later?
And what should I do to install RAID 0 with my stuff? I appreciate all supports.
Thank for read and answer my topic!

The 660ti will require a bios update to use most likely.
Is the system stable enough to flash? The forum flash tool included memtest, run this an so long as no errors or crashes, go ahead a flash to the most recent bios.

Boot problems with Z77A-G45

Quote from: CMaster on 22-June-12, 15:31:08
Processor: Intel i5-3570K retail (new)

Once everything is all connected up, installed in the case, etc etc, upon power up, the fans all spin up, HDDs initialize etc. Then after 10 seconds or so the system powers down again, with the screen (whether on the external or internal graphics) never having been active. There are no beeps from the PC speaker whatsoever, nor do there seem to be any indicator lights as I've had on previous MSI motherboards. The manual is completely absent of any troubleshooting section. So my main question is, is there any way to tell what stage the startup is failing on? Other threads on this forum (here and here) suggest that the problem is due to lack of processor support. As the motherboard was sold as Ivy Bridge ready, I'd like soe way of confirming this as most likely cause before paying for some fix.
Hey I am actaully sharing the similar problem of yours....
I am using MSI H77MA-G43 (BIOS v1.5), and a set of DDR3-1600 4GB RAM x 2.
When i am using both 2 pcs of RAM, i am facing the same problem:
"after 10 seconds or so the system powers down again, with the screen (whether on the external or internal graphics) never having been active. There are no beeps from the PC speaker whatsoever, nor do there seem to be any indicator lights as I've had on previous MSI motherboards. "
When I use 1 pc of DDR3-1600 4GB RAM, it works again.
I just wonder if there is some RAM compatibility problem with MSI motherboard...I have tried below 2 sets of RAM:
AMD DDR3-1600 4GB x 2 (1.5V) (AE38G1609U2K-U)
Kingston HYPER-X DDR3-1600 4GB x 2 (1.65V) (KHX1600C9D3K2/8GX)
Cheers!

Please don't hijack other's topics. >>Please read and comply with the Forum Rules.<<
Your components are not the same, starting with the RAM. >>Posting Guide<<
Please supply your full system spec.
Your RAM is 1,65V overvolted DDR3-1600.
Only add one module as per the instructions. Then do a full CMOS clear with power cord removed. >>Clear CMOS Guide<<
Afterwards go into the BIOS and set that memory to 1333, (ensure that XMP is disabled for now). Set the DRAM voltage to 1,5V. Retest and advise.

MSI Z77A - G45 - CPU multiplier problem

Hi,
I recently bought this PC:
Intel Core i5 3570 k
MSI Z77A - G45 - with BIOS V 2.5
Seasonic S12II-620 620W
Corsair Vengeance Low Profile White 8GB (2x4GB) DDR3 1600
Amd HD 7850
My problem is following:
If I change CPU Ratio (multiplier), in standart mode to 40x and leave CPU core voltage auto, it cause instability, even if use Cpu core voltage 1.25 V for ratio 40x.
But that's not all problem. I could understand, why I cant OC my CPU, but this instability is even if I change multiplier to 30x from default 34x and this makes me uncertain.
Now I will describe you that instability...
OK so, when I change ratio to 40x or 30x it doesn't matter, it runs to windows successfully but after using windows something about 3-6 hours pc turns off.
I also discovered second problem by coincidence. If I hit F11 (Boot menu) , when I am starting pc and I have set ratio 40x or 30x, I can choose what I want to boot only for 10 secs and after that PC restarts by itself....
But if I set default 34x ratio I can choose what I want to boot forever and pc doesnt restart.
I know that boot menu is not some test of stability but it is very strange... Why If I change multiplier, it doesnt matter, if it is higher or lower then default settings it just cause instability ? :-/
Thanks for help.

I was just saying that the beta caused a vga problem, latest release the f11 problem so try the release prior to that, but if you got it working don't touch it! lol
Are you still using the beta bios?
No clue, we are just users like you are, just keep checking the website. You should report the troubles you had with 2.4 to msi too.>>How to contact MSI.<<
Yeah iťs working now. As I said, I wanted flash older Bios 2.4, so for sure I click on restore defualts in bios (for sure before flashing) in that 2.64 Bios version...
PC restarts and my graphic card started working =)...
So now I am running on that the latest Bios as you refered mi (2.64 beta).
I am running some test of stability on @ 4 GHz with 1.070 V (IBT,Prime,memmaxx,linx,cinebench,occt,super pi, 3d mark) temps are 62 C max...
So I guess it's ok now =)
At the end I have one question :
My Cpu is now running on 40 x ratio all the time, there is no some underoverlocking ratio (16x etc.) when it's in idle. I was thinking the Ivy Bridge overclocking is overclocking of turbo only...
I know It's detail, because I have good temps even in idle with 40x ration (33-39 C) but i want to be assured if it is ok.
EDIT:
And btw I didnť have 2.4 bios flash on, I wanted put them on... But before flashing my 2.64 beta started working right with HD 7850 as is wrote upper.
I had Bios 2.5 before 2.64

Need some help with MSI Z77A-G45 Gaming Motherboard

Hey guys I want to buy the z77a-g45 gaming Motherboard.
but i dont now if i could use my RAM that i own now. could you help me out.

None the less that Corsair kit should work although a 4x4GB kit is not optimal for a dual channel system (as 2x4 or 2x8GB would be ideal). That matched 1.5V kit should none the less work.

MSI Z77A-G45 RAID Issue

Greetings...
Just got a new MSI MoBo and wanted to RAID1 my two WD Caviar Black HDDs. However, everytime I enable RAID and reboot it goes to a black screen with two "Z"s randomly placed in the middle. Once I get to the "black screen", it will only boot to that screen afterwards and needs a CMOS reset to fix. I have tried everything I can think of, but always get the same results. I have successfully installed Windows 7 on one of the drives with AHCI mode enabled, and have also had IDE mode work fine... but as soon as I enable RAID - black screen.
Everything else on the board seems to be fine. Anyone have any ideas?
SYSTEM:
MSI Z77A-G45 mobo
Intel i5-3570 CPU
Coolermaster Hyper 212+ EVO
8GB Crucial DDR3-1600

XFX 260GTX XXX Ed. (Physx)
2 x WD Caviar Black Dual-Proc HDDs
LG DVD Super-Multi Burner
Silverstone Decathalon 850W PSU
Windows 7 Home Premium 64-bit

FIXED - Ended up reflashing the BIOS, which restored the RAID utility. BTW, my G15 keyboard would not register the CTRL-I to get into the utility... I had to use a PS/2 keyboard, which required a CMOS reset in order to recognize. Just posting this in case anyone else runs into this.

MSI z77a-G45 Gaming 3770k overclocking?

I just recently purchased the z77a-G45 Gaming mobo and a i7 3770k, most of my googling would leave me to believe that the 3770k can easily obtain 4.6Ghz with fairly low voltages like 1.16-1.20 vcore; here comes the question...in order for me to obtain some level of stability @ 4.6Ghz I must crank my vcore to 1.4150 with 100% cpu offset resulting in a 1.39 vcore in windows with a 1.38 vcore under load. I have all power saving technologies disabled, pll overvoltage enabled, cpu vdroop offset set to 100%; my question is am I missing something with MSI boards as this is the first one I've ever owned or did I just get a very power hungry 3770k?
General system specs
MSI z77a-G45 Gaming MOBO
i7 3770k CPU
16Gb of Gskill Trident X 2400mhz memory
Corsair HX850 Gold PSU
MSI GTX 670 PE OC
Cooled by custom water loop

Alrighty, appreciate the info; gonna back down to 4.4Ghz as I can maintain stability with 1.275 vcore in bios = 1.26 in windows = 1.24 under load resulting in hottest core never exceeding 70...was really hoping for 4.7-5.0Ghz overclock when most everyone who reviewed this chip in the early days was claiming such great overclocks with such low voltage. But I'll chalk that up to either misinformation or non stability checked overclocks, I guess I'm old school; cause if it can't hold up to a minimum 24hr pass of Prime 95 small fft's it isn't stable in my book. Might consider delidding it in a year or so once the new wears off, I had my i7 920 for about that long before I lapped it into a mirror shine lol. So based on my new information 3770k's on average overclock between 4.4-4.6Ghz and can require up to 1.4 vcore and higher past 4.6Ghz which is where you start to really become thermally limited on liquid as the Ivy Bridge's 22nm technology puts the cores to closely together in combination with intel's cheap ass thermal compound solution. Maximum recommended voltage for 24/7 shouldn't exceed 1.4 vcore without some kick ass cooling or a combination of delidded processor and kick ass cooling cause ideally you want your cores mid 70's and below...that about sum it all up?
