AHCI AND G31TM-P21

Hi everyone
I have the motherboard g31tm-p21 and I wish to buy a ssd disk but it doesn't seems ahci settings on bios. Intel g31 chipset seems to have ahci feature but not on msi g31 motherboard.
Without ahci, I'm not sure if I want to buy a ssd disk.
Thanks

No, that is the northbridge. It has nothing to do with SATA stuff. The Southbridge is what counts and your board has an ICH7 southbridge, which does not support AHCI (only ICH7R and ICH7DH southbridges do). The following southbridges support AHCI:

As you can see, the plain ICH7 chipset (non-R and non-DH) is not in the list.

AHCI is in no way a pre-condition for SSDs. IDE/Legacy Mode will work just fine.

G31TM-P21 One of the usb devices attached to this computer has malfunctioned and

Just bought the G31TM-P21 motherboard and installed it with a E3200 proc. Whenever I plug in a USB device in one of the four ports on the back panel I get the message:
"One of the usb devices attached to this computer has malfunctioned and windows does not recognize it. For assistance in solving this problem, click this message."
After clicking the message I get a window with:
"One of the usb devices attached to this computer has malfunctioned and windows does not recognize it." with a tree of USB Root Hub (2 ports) with Unused Port and Unknown device under it.
If I go to Device Manager nothing appears to be uninstalled but if I expand the USB I do have a single instance of Unknown Device among the root hub and host controller. I'm running windows XP home 32 SP3.

G31TM - P21 boot up bios beeps

I just installed this board into the system. It is unable to boot and gives me 1 beep, sometimes 2 beeps.
I changed memory from a good system and still no results.
I also have this same board and processor and swapped memory from this system to verify if memory was at fault. Memory from bad system shows up good at running system.
any ideas, besides RMA.

Ok, here are my specs
I running a Intel E3300 processor with a MSI G31TM - P21 motherboard with AMI v4.6 bios. I have only one stick of Micron 1 gb pc2-5300 ram installed in slot one. Currently running onboard video. I attempted to run this new setup with a preinstalled 32 bit Vista OS HD(sata, 160 gb). I removed all peripherals with the exception of the USB keyboard/mouse (wireless). No add on cards.
The previous setup was running windows XP on a PATA HD. This info is probably irrelevant since there is nothing similar and I did attempt to run this new system on this PATA drive (known good) and got the same results (beeps).
I have this same setup (upgrade) that I did about 1 month ago on another system. This "older" system is working fine.
I swapped memory from the "older" system since my research tells me that two beeps is a parity issue. Known good memory from the "older" system resulted in no new results. Both set of windows (XP and Vista) attempted to "fix" my problem but were unable to.
I have reverted in the meantime to the previous setup using the PATA HD with XP os and am having no problems with this setup.

Video problem after hibernation on g31tm-p21

Hi everyone,
The G31TM-P21 board is 3 days old and I am using the Internal video mode. I just finished installing Win 7 and everything is working perfectly except for one thing, I cannot put the computer in sleep mode (S3 setting in BIOS). Once the computer is awaken, the screen is defective but still readible for about 5 minutes. Past 5 minutes, everything is perfect.
While the screen was still defective, I rebooted the computer and the screen defects were still visible in the BIOS setup screens. CTR-ALT-DEL did not clear the defect. Turning off the computer and restarting it still showed the defects. The only things to clear the defects are to: unplug the computer for 5 sec or wait 5 minutes.
These are my tests/thoughts:
This is not a driver error as the defects are still visible once rebooted and in the BIOS Setup menu.
As it last for only 5 minutes, I suspected a temperature issue but the board is running at 30C and I would wait for 8 hrs before waking up the computer and still see the defects. Therefore, not a temperature issue. It looks like the Hibernate state leaves the video chip in a screwed mode.
The only 2 things to correct the screen defects are wait 5 minutes(computer running in BIOS setup screen or Win7) or unpluging the computer for 5 sec.
I reinstalled the BIOS from MSI with the same results. BIOS version is 4.7
I suspect there is a bug in the BIOS, my BIOS setting is wrong or the board is defective.
If you have any suggestions, please go ahead otherwise I will RMA the board within a week.
Thanks

My computer is a standard Acer Aspire M6540 computer. All parts are original from the 2 years old computer except for the motherboard which died on me and had to be replaced with the G31TM-P21. I have never overclocked or modified the computer and it is now working perfectly with the G31TH-P21 board as long as I do not put in in the sleep mode. I believe the original Acer MB was from MSI.

MSI G31TM-P21

Recently purchased a MSI G31TM-P21 and a Celeron e3400 wolfdale. The board is listed as supporting this cpu but on newegg I found a review stating that there was a problem with this cpu and the bios resulting in a bios flash to resolve the problem. Is this still a problem to anyones knowledge? And if so how can i flash the bios to get these two components to work together? Thank you in advance.

So long as the motherboard's BIOS is updated to version 4.5 it will work fine. >>Use the MSI HQ Forum USB flasher<<
See if it boots first.

P4 HT 650 possible on G31TM-P21?

My sister has a Dell GX280 with a P4 HT 650 that I would like to put in a new case with my old G31TM-P21 board. The are no P4 HTs on the approved list, however this reviewer (neweggdotcom/Product/Product.aspx?Item=13-130-234&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Keywords=ht) claims to be running a 531 on it without issue. Anyone know if it really possible and whether it could hurt to try the combo?
Thanks!

That P4 CPU is too old to use on the G31TM-P21. None of the old P4s will work on it. That 531 is even older than the 650 so I don't see how it would work.
That guy you refer to probably has a G31M3/4 MB of one variety or other and doesn't know what he's doing posting his review/remarks for the G31TM-P21 MB.
You need to go by MSI list or this one which would be more up to date than the MSI CPU support list:

G31TM-P21 Onboard LAN Wont Work!!!!

I have read. I have searched. I have spent almost a day on this. It has to be easier than this. I had a wireless card. I had to move computer. It doesn't receieve the wireless signal that well anymore. I say "I'll run a cable and use the on board LAN". I bought a new cable. Before I started I checked it (worked properly). Then I disconnected and uninstalled the wireless card. Downloaded the drivers for the mobo LAN (I have no idea where my disk is?).
I have it to the point where the computer is recognizing the PCI-E family controller as the Network adapter but it says the cable is unplugged (it is not and has been triple checked). It also wants to install a PCI device and SMS controller (I can't get these to install at all - it rejects all drivers I throw at it). I have the drivers from MSI. It didn't take them.
Windows XP SP2
G31TM-P21 mobo
in Set up I have on board LAN enabled and LAN ROM enabled
PCI-e graphics card (I don't remember which one and I'm too frustrated to go look)
Am I missing something simple?? I usually can solve all my computer problems after this amount of time. I'm severely frustrated (this typing did help though). If I need to post more info let me know.
I need to go take a walk.

I'll check the cable again. But I still can't get past this phantom PCI device it is finding. So when I switched to onboard LAN it found 1.) PCI-e Family 2.) SMS Controller and 3.) PCI device. I have gotten the drivers to taken for items 1 and 2 (I found the install disk) but for the life of me I can't get the third thing (the phantom PCI) to install. It is not giving me any clues what i need either.
I'll try again tonight but any help wouldbe appreciated.
I did this on one of other computers last year and all I had to do was change it in the BIOS. No install. No drivers needed. Why is this so complicated.

Problem with 8800GT + MSI G31TM-P21

For a while now, I've been using an 8800GT + MSI G31TM-P21 as a secondary gaming system. This has been working admirably for a few months. Lately though, I've moved the board to a new case+PSU, have changed out the RAM and added a new hard drive. Now, I'm starting to have problems. The system will boot with the 8800GT + WinXP, but is sluggish and crashes (usually a crash to desktop instead of a complete lockup) within 5 minutes of launching a 3d game. The 8800GT works fine in another system - it stood up fine to an extended gaming session on a different P35 board. I loaded Win8 just for testing purposes, and the display driver crashed just doing desktop operations. I also ran Memtest86+ for about 12 hours on the RAM with no failures. The head scratcher is that an even more ancient Radeon X1800 GTO seems to work fine with the MSI board. System config is below:
MSI G31TM-P21 (not sure about BIOS rev)
Intel Pentium Dual-core E5500 @ 2.8GHz
2x2GB Kingston Value RAM 800MHz DDR2 (dual channel)
LG DVD+RW
2x7200RPM drives and one 5000+ RPM "Green" drive
Windows XP SP3 32-bit
Arrow "500w MAX" PSU
A bit more about the PSU - it's a cheap, older model with a 20-pin power connector. As I understand it (and I could be wrong) the extra 4 pins just power the PCIe video card, which are unnecessary since the video card has a power cable all its own. This setup worked fine in my old case, with an even older PSU. I guess my next step would be to resurrect my old 300w PSU and see if it works properly, but I wanted to see if anyone else had any ideas before I tear my case apart. BTW, there is no overclocking going on anywhere in this setup...
UPDATE: Took a closer look at the old PSU, and it was an Allied/Apex 300 watt with (get this) 10 amps on the +12v rail. Nonetheless the 8800GT seemed to work fine on it. The "new" PSU has 17 amps on the +12v rail.

That $25 Arrow 500W with +12V~17A is a joke. Any decent 500W PSU should have at least +12V~30A. I wouldn't trust that thing any further that I could throw it and at my age that's not very far. Even a Corsair 3 year old VX450W that I have has +12V~33A. You need minimum of +12V~26A for system with that graphics card to begin with, see the chart here: https://forum-en.msi.com/faq/article/power-requirements-for-graphics-cards. You're lucky that PSU you had before worked at all in your system.
Get a Corsair PSU, a CX430W V2 +12V~28A would do but better would be the CX500 V2 +12V~34A. Even more power would be needed if you intend to upgrade to later and greater more power hungry VGA card any time soon.. See the Corsairs here:

New MSI Motherboard G31TM-P21 bios recovery

So I just got a new motherboard delivered to me yesterday from Newegg and installed it right away. At first it was working fine I just had a few other problems going on, just put a newly bought Pentium Dual core inside it and was trying to increase the processor speed thru the bios bus clock. So what happened was my friend recommended me trying to get to 3.8 ghz (originally 3.00 ghz), when I was currently on 3.3 ghz or so from increasing the bus clock to 220 (default 200). That seemed to be working out fine so I decided I'd try to get to 3.8. The bus clock on that turned out to be 254, and at the time I didnt even think about lowering ratios or ram/gpu affections. I restarted after saving the settings and then my computer started to just stop loading all together. It was like it was trying to load everything normally but would stop at random points and stay on whatever screen was there last.
So now comes the problem, after a few reboots of freezing, I finally ended up just getting a Bios recovery requested screen before any type of other screen shows up. Its telling me to put in a usb with the bios file for the motherboard. I've had my friend helping me look up problems and we've tried soo many tests, all of them resulted in the same bios recovery screen.
-Using 1 stick of unnaffected RAM
-Clearing CMOS by taking out battery for at least 5 minutes
-CMOS Jumper clearing
I've also tried to create a bootable USB for bios flashing and put in the latest bios file and flash tool onto the USB. That results in a screen saying,
"Please copy latest BIOS file into USB flash drive to recover your BIOS
File not found"
then it loops that until I take out the USB or turn off the computer.
Also there is no FSB switch on my motherboard like there is supposed to be, there is an empty square with 6 solder holes on the board so I cant toggle the FSB back to default using those switches.
I was using this to make a usb bootable for bios flashing: http://www.biosflash.com/e/bios-boot-usb-stick.htm
and I was using these files from MSI to transfer on USB after making bootable USB: http://www.msi.com/product/mb/G31TM-P21.html#/?div=BIOS
So... if anyone can help me to make this work at all I would very much appreciate it. Once I get the bios working again (assuming I can) I'm keeping to default.

Well with the CMOS clearing I already did all of the above, except I left out the battery for 5 minutes, and ended up with the same result for bios recovery. I want to clarify that I cannot even get to the BIOS, as soon as I boot with that motherboard I get an instant black screen with text telling me to insert a USB flash drive with the latest BIOS file. There is no type of menu or anything of any kind.
The specifications of this build was:
MSI G31TM-P21, MS-7529 Version 1.6 (New motherboard)
Intel Pentium Dual Core E5700 3.00GHz (New Processor)
2 x1GB of DDR2 667 or 800 not sure (same ram on my old motherboard)
Nvidia 8600GT 256 MB DDR3 (same card on old motherboard)
300W Power supply (efficient enough to run old build)
Windows 7 Ultimate 32 bit
Thats about all I can think to add right now that you would possibly need. I know the 2 x1GB of memory still works, as its in my old motherboard again and thats what I'm currently on. I dont have any other way of testing if the Processor was fried, but I'm pretty confident that it was capable of that overclocked speed since there were reviews saying so. If there's any other way I can help please let me know what u need, I would love to get this working.

Problems with G31TM-P21

I`m trying to put a system together but something is wrong with the motherboard .
Mobo: G31TM-P21
Processor: Core 2 Duo E6300
RAM: Apacer 2x1GB 667
GPU: onboard / PALIT 8600GT SONIC
PSU: 400W CHIEFTEC ( 40Amps / 12V Rail )
Bios Version: no idea ( green sticker on bios chip is missing )
Ok so here is the thing ... the E6300 is on the supported CPU list , and should work with any BIOS version . I`ve tested this motherboard about 2-3 months ago with a Celeron dual core , and it was working ( well kinda ) . I couldn`t get into bios though , all i was getting was a message with PXE LAN ROM , can`t remember it . I think it was trying to boot from Lan or something , i might be wrong . So i left it there , in its box , and a couple of days ago i wanted to try a bios update to see if i can fix the PXE LAN ROM thingy . But the board won`t even post with that processor installed .
I tried clearing CMOS ( by jumper , by removing the battery ) a couple of times , and same thing . And no , i didn`t try to reset the bios with the jumper missing , with the board still running , and i did not forger the jumper in clear state .
I`d like to add that im not the first owner , and i have no idea what the previous owner did , or if the motherboard ever worked .
So i have a couple of questions :
1. Is it possible that one CPU ( listed in the PSL as working since the first bios release ) not to actually work ? Anyone encountered such a problem before ?
2. Is it possible that the motherboard came with a wrong bios in the first place ? since i see that its a G31TM-P21 board but under the sticker , there is another motherboard version "hard - printed" . I checked , it seems that there are 3 mobo versions that uses the same PCB and prolly use the same bios anyway , but who knows ..
Things that i want to add : The e6300 is just fine , it works on another motherboard .
The Apacer ram modules work , and are on the QVL .
I tried with different ram modules / same thing , but i really don`t think that the ram is the problem here sinse the board won`t beep without the modules installed . I tried with only one ram module / first slot closer to the cpu socket , switched the ram around . The other modules that i tried with are from Corsair ( 800mhz dimms ) .
The PSU is a pretty decent one , and it`s working properly .
I tried with a dedicated video card , and with the onboard one , same thing .
I cleared cmos everytime i made a hardware change .
I checked some voltages and tbh everything seems OK !
Things that i haven`t tried yet :
BIOS recovery procedures / updating bios , with floppy or cd-rom / sata port . Blind flash or whatever it is called ( but i doubt that would work in my case )...
I don`t have another processor for now , so i can test with . I will try to find another Celeron Dual core that i used the first time and give it another try .

like i said , i tried to clear cmos a couple of times by removing the battery and also by placing the jumper in clear pos. . It didn`t work . I`ve used a true PS/2 keyboard , and also tried an USB one with / without an USB to PS2 adapter . It didn`t work ( the manual says that i should hit DEL key , but i also tried F2 F10 and so on , nothing was happening) . I was seeing that MSI splashscreen (logo) without any messages like : press "key" to enter bios or press F12 for boot menu or whatever . Just the splashscreen and after about 5 seconds that : PXE LAN ROM message . This was when the board was posting with that celeron dual core installed . with the E6300 it wont even post so i can`t really get to the point where i should be able to go into Bios or at least try to . I connected a speaker ( buzzer ) to the SPK headers and i get no beeps whatsoever .
So anyway ... anyone encountered such a problem ? A CPU on the Supported CPU list that doesn`t actually work until you update the BIOS to a more recent version / release ?
Ill try to find a celeron dual core E1200 or E1400 to see if the board still works with it and if it does , ill try to update the bios with the CTRL+HOME method .

"BIOS Expand" after POST, G31TM-P21

I installed a second-hand Adaptec AHA-2940 /2940U PCI SCSI-2 Adapter. Right after POST, I get a "BIOS Expand" message and the boot halts. According to Adaptec's site:
"This error usually indicates that the motherboard BIOS is incompatible with the Adaptec RAID controller BIOS. Please contact the motherboard manufacturer for the latest Motherboard Flash BIOS update."
I haven't tried the latest BIOS update. I'm mostly curious to know if this was ever addressed in an update or if this board can support a SCSI controller card. Yes, I know it's an ancient controller. Has anyone had luck with a newer one?
This is an MSI G31TM-P21 board. MS-7529 Ver. 1.6.

That is something you would need to contact MSI about, there's nothing we can do about BIOS hardware support here.

Pavillion g6 ahci and ide

Hi I have hp pavillion g6-1075er laptop and I'am wondering how to change hdd mode to ahci and ide. I haven't found way in bios. I'm thinking about buying ssd. For firmware update I need accses ide, for general usage ahci to enable trim.

Hi,
If the SSD manufacturer is adamant on IDE mode for updating then chose a differnet SSD manufacturer.
Many of the newer SSDs support W7 trim (ACHI mode) and garbage collection for older PCs and RAID mode (trim is not available in RAID mode).
I am using the Crucial C300 128GB in one laptop and the Vertex 3 in another laptop and in two differnet PCs.
The Vertex 2 120 MB might be a good choice for you. And, since you can update firmware from a boot CD then you don't have to deal with the IDE restriction.
Look over the Vertex SSDs.

G31TM-P21 and E3200 Overclock

Hello gang. I was on another site and many of the people that have this same combo are able to crank the E3200 from it's core speed of 2.4Ghz to 3.00Ghz. There's only one problem. How in the world are people able to get this? Everytime I change the FSB to 250 it flashes a red sentence if I want to keep these settings. I, of course, press the "Y" versus the "N" to confirm the settings. I just want to know what in the world am I doing wrong here. Is there something you have to turn off in the BIOS to get this clock? Is there something I have to do with my 2Ghz paired OCZ 800 DDR2 memory? Please help. Thank you ever so much. :smiley:

The memory clock speed is tied to the FSB Frequency. That means if your memory is set to work @DDR2-800 (via the FSB/Memory Ratio Option) then it will become DDR2-1000 if you increase the FSB Clock Speed to 250 MHz. The memory will be highly overclocked and the system becomes instable.
Again, please give a FULL overview of your system configuration! Read the >>Posting Guide<< to get an idea of what we need know.
Quote
I just changed the fsb to 250 and thought that the CPU would just adjust. I'm really new to MSI as a whole.
The basic clock relation has nothing to do with MSI. It will be exactly the same on every mainboard with this kind of chipset architecture.

In this mobo there are checksum issues with this card that the 9600 GT never had. I know because after i got the first checksum, i removed the card and reinserted the 9600 GT . no checksum. switched to 4850, checksum Here was what I did to try to remedy this
1. Cleared the jumper cable, checksum
2. Removed CMOS battery for 15 minutes and reinserted, checksum
3. Upgraded BIOS from 4.1 to 4.4 via liveupdate. Still checksum but the latest BIOS feels a lot smoother
4. repeated step 2 after the BIOS update, checksum
5. added a Visiontek juicebox, checksum as it's not a Power issue
I seriously doubt it's the voltage battery because it's a new mobo and i never got the checksum error on the 9600 GT.
Can someone help me please?

What issue you have

Windows 8 64-bit install on 970a-g46 Mainboard AHCI and NVIDIA DRIVER issues

My Box:
MSI 970A-G46
BIOS 1.9 (AUG 2012) (Tried 1.11 but the nightmare started then)
AMD FX-6100 (STOCK SPEED AND SETTINGS) WITH OEM HSF
16GB PATRIOT VIPER 3 (1866) RUNNING @ (1600)
USED an EVGA 9800GT 1ST AND UPGRADED TO NVIDIA REFERENCE CARD GTX 550 Ti (1GB) WITH SAME ISSUES
90gb MonsterDigital Daytona SATA III SSD DRIVE (OS and minimal programs)
Antec HE 550
I am at a point of pulling my hair out. I decided to upgrade my system to enhance Diablo III game play. I got a combo deal on the mainboard and cpu, and thought the speed of the game caching on a SSD would also help. The first attempt which took a little struggle was Vista 64-bit. Eventually, I was able to get the OS to work with me, and it was smooth. Since M$ decided to offer the Windows 8 Pro upgrade for only $39.99, I thought, what do I had to lose. Well….lots of time. Now, I am not a newbie, though SSD drives haven’t been more than an interesting thought. So yes, I read many guides on everything from Trim enabled Win 7 and 8, and many other do’s and don’ts. What is driving me to the Netherlands of hell, is the installation and how buggy it has been. It boils down to drivers for the IDE/SATA/AHCI CONTROLLER. First, even thought it “sees” the SSD on installation drive selection, after pulling the USB installation drive, the system forgets it, and there is a “problem with the boot sector”. If you load the driver from the AMD site, it lets the install occur “fine”, but there is an issue with that driver which causes an irq conflict which leads to D3 audio issues and freeze ups. I did finally get things in order (not sure which driver I choose for that), and things were smooth, except I tried to install the GTX 550 ti and that led to a corrupt file error, which the system runs a check disk and cycles the “preparing to repair” and “diagnosing PC” a few times and never allows me to enter SAFE MODE (shift+f8), to disable the NVIDIA driver that is buggy, and doesn’t allow for the NVIDIA Control Panel to install without losing video, and starts the repair cycles again… Leading to ANOTHER RE-INSTALL...
My question, for the Windows 8 Pro installation on the 970a-G46 mainboard and then after install is complete, which driver is the correct choice for the AHCI/SATA Controller? All I find is Win7 64-bit AHCI inf’s, and SB7XX 64-bit inf’s (no SB950 INF). The Driver disk which came with the mainboard is very dated pre Win 8 stuff, ASMEDIA X106 which are not recognized by the OS as written for Win 8. AMD’s latest drivers are the ones causing the IRQ type lags and corruption.
What version, build and type of Windows 8 installations have you used on this mainboard, and what drivers allowed you install it without the above conflicts? Your input may decrease my insanity… So, thank you in advance…

Quote from: m0r9h3u5 on 28-January-13, 12:11:16
I understand what you are telling me, only the generic drivers deliver subpar results. What is the point of running those drivers instead of windows 8 certified drivers written for said devices. My last install is functioning better, but still windows update fails every attempt, the apps i install (ie. weather bug) on the start screen wont load... to me windows 8 is a big fail....but that is just my view...
OK...I also own the 970a G46, and my upgrade experience from Win7 x64 AHCI to Win8 x64 AHCI was flawless the first time. No problems at all. You are running an AMD chipset board with a nVidia gpu, which means that your chipset drivers are not automatically updated with every gpu driver update you do--this would happen automatically if you owned an AMD gpu because AMD includes them in its gpu driver install packages. But--all you have to do to get the proper drivers for your motherboard is go here and download them. You only need the *chipset drivers* from this page--you do not need the RAID drivers, of course. That's it. It's no big deal, and back in the days when nVidia was making motherboard chipsets you had to separately download both the motherboard chipset drivers from nVidia and the AMD gpu drivers from AMD if you did not also own a nVidia gpu.
From your description of your problems it sounds like your installation of Win8 is hosed and you need to format C:\ and clean install from scratch, anyway, so...
A note about AHCI--the *ideal* way to install the AHCI drivers is prior to installing your OS for the first time, you enter the UEFI and set "AHCI" in the appropriate place, instead of IDE, and *then* you reboot from DVD and install your OS which will automatically install the correct AHCI driver from Windows. After the driver installation is complete you should then install the updated 970a drivers from AMD as linked above.
However, it is actually very easy to activate and install AHCI *after* you have installed Windows in normal IDE mode:
To enable AHCI in existing Windows 8 IDE Installation's
Caution: Do NOT enable AHCI in UEFI prior to making the following changes in your Registry! If you had AHCI enabled alreadyin UEFI, disable it first and restart your computer!
Use WinKey + R and type Regedit in the command line and hit the Enter key, this will open the Registration Editor.
Go to:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/iaStorV
right click on Start, select Modify and set Data Value to 0
Close Registration Editor and restart computer.
While booting, open the UEFI Page and set the SATA Mode to AHCI from IDE
Save UEFI settings and restart.
Windows will now install the AHCI drivers automatically and they should work without issues.
In order to avoid installation problems just like you have been experiencing, here is what I would do in your shoes:
1) Set UEFI for normal IDE drive mode
2) Reboot into IDE mode and install your OS
3) After you have finished with the installation, you should be having no troubles in IDE mode. Then go to the instructions above on how to properly enable AHCI *after* you have installed Windows 8 in normal IDE mode.
4) After everything is coming up roses in AHCI mode and you are having no problems, then install the AMD chipset drivers as linked above and you are golden.
Those 4 steps worked perfectly for me the first time (the first time I got them right, that is...).
There's nothing wrong with Win8--this is strictly operator error caused by insufficient research into what AHCI is and how to properly enable it. The Internet has some bad info on Win8 registry settings for AHCI because of the developer preview and the consumer preview versions of Win8 that Microsoft released to the public prior to the final shipping build--many "instructions" for Win8 are therefore not valid for the shipping version of Win8. At first I made some of the same goofs that you did, but now you get to benefit from my hard-won experience... Good luck! Should work like a charm. And, registry AHCI is done differently in Win8 than it is done in Win7 or Vista. Also, the registry settings relative to AHCI in Windows 8 for AMD are different from the registry values that must be changed for an Intel controller.
Parenthetically, My FX-6300 (Vishera) will be here in a couple of days! Yeah!
