KA790GX (MS-7551) pci-e @ X4 FAULT?

Hello Guys.
Ive just ran cpuz and It says that the pci-e link width is at x4.
It should be x16 yes?

Msi ka790gx and dual monitor

I have a question about the msi ka790gx
i need to plug two monitor use two monitor it is possible using the igp? i saw that the motherboard have both dvi and vga port, it's possible use both the port concurrently in order to have an expand desktop?
tank you for your kind attention and i'm apologize for my bad english
Luca

Quote from: Bas on 26-February-09, 19:11:56
No, you need an extra card to do that.
How do you set the BIOS to allow use of IGP & Card?
Also I read (damn these magazines) that you could use the DVI & HDMI for 2 monitors. I assume from your comment that is not true?
Thanks

Need Help with a new processor for my KA790GX

Hi guy"s I was just wondering if I can run this Processor
http://www.canadacomputers.com/index.php?do=ShowProduct&cmd=pd&pid=027384&cid=CPU.907
On my KA790GX.
Thx

Quote from: blazing storm on 08-February-10, 05:32:10
The CPU compatibility list for your board indeed states it supports the AMD Phenom II X4 965 Black Edition.
You will need to update the BIOS to version 1.6 though.
Awesome, Thx..... I did the bios update to 1.6 I was just checking to make sure

MSI KA790GX+Mionix Saiph 3200 incompatibility?

Hi guys!
I bought a MSI KA790GX motherboard 2 years ago. One year ago I bought an Mionix Saiph 3200 mouse.
I've plugged it in and everything worked perfect until first reboot. When windows is loading, mouse lights are turned on, but as soon as it's loaded, the lights turn off and I must replug the mouse to work. Sometimes it works well, without the need to replug it, I think in 10% of cases.
I have tried everything: all usb ports, all bios versions available in support section, 3 different OS(Windows Xp, Vista, Seven) and nothing seemed to resolve this problem. Then I tried the mouse with my friends systems and it worked perfect after every reboot. I think it's an incompatibility problem with KA790GX and Mionix Saiph 3200, please, can anyone from MSI support check it and release a bios that resolves this?
Thank you!

You can contact MSI's Technical Support department here: http://support.msi.com/
Done that already, they told me I should contact the store from where I bought the motherboard. I followed their advice, contacted the store and I explained them the problem. One guy from there asked me about some basic settings and after that I asked him nicely to contact MSI technical support. After one month I've contacted him and he told me that romanian MSI supplier didn't reply him. Then, I gave up.

>>Posting Guide<<
In this case, I found system specs somehow irrelevant, but here they are:
Motherboard: MSI KA790GX
CPU: AMD Phenom II 720BE
Memory: 2x2GB Team Xtreem Dark PC2 8500 DDR2
GPU: HIS ATI 4670
PSU: Corsair VX450 - voltages are normal
OS: Windows 7 Ultimate x64
The system isn't overclocked and is stable. For example, my old A4tech SWOP-23 mice and other usb devices work fine.
Thank you!

KA790GX-M fest time cant boot? reset 1 or 2 time boot back!

I have this MSI KA790GX-M about three month old

Problem every time morning i on the CPU not display nothing booting, i need to click reset button one or two time, it booting display runnning. what can i do about this problem?
Pls help me.......

12V1~16A, 12V2~18A, no way. And that is maximum output, sad, very sad.
+12V 216W = 18A.
I sure hope you don't have a separate VGA card you want to use. I would get rid of that PSU in a heartbeat and get a Corsair CX400W or VX450W.

KA790GX HARDWARE VIRTUALISATION

I have a ka790gx with bios 1.4.In bios cpu features there is no option for enable virtualisation.My cpu is AMD Athlon 64 x2 dual Core 5200+ 2,7ghz i think it supports AmdV(vt,hardware virtualisation.It is a very important because i need this option in my work.Is there any way that this option can be enabled?Thanks in advance

Quote from: Bas on 26-May-09, 15:55:04
It is turned off when using an AM2 X2 CPU because of problems in the CPU.
You need an AM2+ or AM3 CPU to use it.
Just got the answer from MSI as I was puzzled too why my CPU has the function and the BIOS disables it.
Simply put, get a newer CPU and it will work.
Which is crap, since AMD-v worked fine on my previous ASRock AM2+ board (paired with an AM2 X2 6000 Windsor). AMD-v always worked fine in VirtualBox 2.2.2. I got a KA790GX since a few days and it is also paired with that 6000+ (until my 7750BE arrives) and now it is disabled.
Pretty stupid since other 790FX/GX boards offer support on those cpu's.

No boot with KA790GX-F and HD4850

Hi all
As the subject say's I am not getting any boot from my pc using a KA790GX-F mobo and 4850. There are no beeps at all and just a blank screen. When I boot the pc the screen tells me there is no signal which it always does at the start but then goes blank as if it's kicked into a power saving mode which the monitor doesn't have. As i'm also using the screens speakers and have also disabled the windows startup sound I have no idea if it's actually booting through to that point BUT the hdd's are being accessed and the dvd drive is being checked so I am assuming that the booting process is happening correctly.
That leaves me thinking my Powercolor graphics card has died (does have the stock cooler on it still and has already melted the sticker they put on to say it's one of theres and not someone elses). Could it be anything else?

Quote from: Hans on 24-September-09, 19:10:48
What sound card is that? The onboard sound or a seperate sound card?
The onboard sound is pretty good. Wouldn't go for seperate sound device.
Creative Labs Audigy ZS Platinum.
Have put it back in and the PC booted fine so have left it in as I actually do hear a difference between the on board and the Audigy even with crappy speakers that are built into my monitor.

Having a small problem with my KA790GX Mobo

Hi guy"s I have recently picked up a KA790GX and when I did the initial build I had installed 4X1gig Crucial Balistix DDR2 1066
The computer would not boot, I tried
1 stick booted fine
2 sticks booted fine
3 sticks booted fine
4 sticks would not boot
I flashed the mobo to the latest BIOS 1.6 with the same result"s.I would like to use all 4 stick"s
Can you help?
Spec"s are as follows
AMD 9850Quad Core
EVGA 260 Pcie video card
My memory (three stick"s running now)
3hd"s
1 DVD rom
And a 600 watt enermax Ps
I can provide any additional info if needed
Thx.

Quote from: Hans on 05-January-10, 02:41:23
Ah, that solves it.
I forgot to mention: you can run 4 dimms, but not at full speed. You need to fall back to 800MHz when the cpu supports 1066. In your case, this is true. So running at 800MHz shouldn't give any trouble.
Is there a particular setting in bios I need to set to do 800 or is it set to AUTO,or just set it to 400.

A few questions about the ka790gx and dka790gx

i have a few questions about the ka790gx and dka790gx , how much better is the dka790gx compaired to the ka790gx ? . how much difference does the ACC function make to overclocking etc , i plan on getting a phenom II 940BE or 720BE . i already have the ka790gx so would it be worth building another system using the dka790gx mobo , or should i keep what i already have and just change the cpu ?

It's largely irrelevant what other boards had VRM issues other than the KA790GX - the fact is it died at stock settings. Since there is little cost difference between the more robust DKA790GX (or Platinum if you really need 1394) why bother with the proven weakling? There are other examples around of the KA not having a robust power section. There's no way I would use even a 95W TDP CPU in the KA and absolutely not O/C.....!
As for the credentials of Custom PC, I have generally found their reviews accurate and balanced, and echo my own findings where applicable. If a little too infrequent.
The fact that the KA has such a huge VRM heatsink leads me to my other comments on the Forum, particularly regarding the "fudge" aspect:
"""Henry is spot on - the notion that adding a heatsink to the top of the D2PAK or whatever MOSFETS is effective is virtually worthless. The device's die thermal junction is the tab on the device back - which is always against the PCB pad. The majority of heat is therefore dissipated in to the board, and the fact that the epoxy plastic encapsulation gets hot is simply due to the inability of the heat to be conducted away from the device die via the tab. Not sure when Epoxy become an effective conductor of heat.... Good practice is to increase the size of the PCB pad (or "land" in American) such that the enlarged PCB copper area acts as an adequate heatsink. This is still not as effective as clamping a power device tab to an actual piece of ali or copper, but since the devices used are SMD devices, this is not possible. However, the surface area required to provide sufficient PCB copper area to act as a heatsink for several devices isn't available in the current motherboard layouts. Where industrial SBC designs differ in this respect is to place the VRM MOSFETs on the back of the PCB on very enlarged PCB pads - where real estate for components is not an issue.
Gigabyte's UD3 2oz copper mainboards sound like a good idea, on the face of it. However, without knowing how they have connected the device tabs to where and what remains a mystery. I suspect it is more hype than solution, although there will be some positive effect. From an electrical perspective, having lower resistance connecting whatever to whatever (probably just a 0V plane) is no bad thing.
The way the likes of ASUS sort of get round the problem is to increase the sheer number of MOSFET devices and effectively spread the heat dissipation over a larger physical area. This works to a degree, there is the same amount of heat being dissipated, but over several more square inches. The other advantage of this is that each leg of the VRM circuit passes less current and therefore localised heat is reduced. Remember that as well as absolute peak operating temperature causing reduced component life, thermal cycling stresses the mechanical aspects of components (die wire bonds for example) as well as the solder joints on the board. Keeping components at a relatively constant temperature, even if this is high (but within operating temperature limits), is a means of promoting longevity.
For myself, the first thing I do with a seperate VRM heatsink is take it off and use a quiet fan to blow air on to the VRM area of the PCB - this is where the heat is. This has the added benefit of actively cooling the inductors and capacitors too....
Cooling the epoxy component body is a fudge. If the epoxy (and thus any heatsink plonked on top of it) is running at 60C, the component die is way above that.....
It's better than nothing, but only just."""

Hyper-V enabled BIOS for DKA790GX / KA790GX / K9A2 / K9A2CF / KA780G

Hi guy's,
Well good news, I received a bunch of BIOS'ses from MSI that have Hyper-V enabled.
The BIOS are released here as Hyper-V doesn't work for every CPU even if it does have it.
If it works it work, if it doesn't you are out of luck.
The BIOS is attached and we STRONLY recommend you >>Use the MSI HQ Forum USB flasher<<!!
Have fun with them, but beware, they are for use at your own risk!! Nor do we know if they will have new versions in the future.

KA790GX overclocking problems!

The oc with the dip switch goes.
But!
When is a change the fsb in bios (and the multipliers-ht,ram,nb- and voltages) the other settings changed well but fsb doesn't! It is still at 200mhz. The bios calculates the fequencies well(eg 2800mhz) i save the settings, and after the restart when i goes to the bios it indicates the same frequencies, BUT when i boot to windows the fsb will 200mhz again :(.
Can you help me?

There is nothing locked, use correct keys to adjust values ==> PageUp/PageDown or Num Pads +/- keys
I've found why doesn't work the ACC on my board...
MSI is liar! MSI lies to us with the cipset!
This is 780G... this is not problem, when the SB is SB750 and whne the overclocking workx, but NOT!

Overclocking with ka790gx

im new to overclocking.. the bios in this board, under cpu voltages, it only allows me to set from 0.01 to 0.4.. wat does that means??
how am i gonna set the cpu voltage??
previously, i check with cpuz.. it showing 1.34v at default. if i set 0.01 in bios will it means i hav a total of 1.35v??

pleas help me oc this cpu

BIOS HTT (FSB) Setting in KA790GX

I also have the problem with this board and BIOS O/C of CPU FSB reported in another thread.
When I try to increase the FSB MHz setting in BIOS 'Cell Menu' from 200MHz to anything else - e.g 201, 210, 215 it can be set OK in BIOS and saved but when booted into Windows or MemTest, it only ever shows 200MHz in CPU-ID, Windows or Memtest. However, the 'Cell Menu' in BIOS always shows the new setting although the set value does not load, it always says 200 in Windows etc and runs at 200MHz.
However, if I set the mainboard hardware OC switches to 10% (Switch 1 on, 2 off), then the resulting setting of 220MHz loads up, the system runs at that setting and is very stable.
However, I would rather fine tune the FSB & RAM settings through 'Cell Menu' than use the coarse mainboard hardware switches.
'Cell Menu' manual RAM settings work properly, if I set 5-4-3-11, then that is what CPU-ID shows the RAM running at.
I have tried all the BIOS's for this board and they are all the same so I think there may be a BIOS error for the KA 790GX system.
I have also contacted MSI directly about this through Online Customer Service.
I also have a MSI DKA 790Gx based system and on this, the BIOS CPU FSB setting does work.

Quote from: Pete B on 19-January-09, 22:00:40
I had not really being trying to achieve any massive O/C from this system, rather just getting the CPU running at it's default 2.5GHz without the RAM taking a hit.
The default CPU speed of 2.5GHz with the default CPU multiplier of x12.5 at FSB (or I suppose, correctly for the AMD based systems - HTT, regardless of what the BIOS setting says) of 200MHz results in RAM running at 714MHz with the ratio set at 1:2.
Reducing the CPU multiplier down to x12 & increasing the HTT to 210MHz then takes the CPU back up to 2.52GHz & the RAM up to 840MHz, a useful speed increase over the default settings. The HTT multiplier is also reduced down to x4 to keep the value below 1GHz.
Quote from: AaronYuri on 19-January-09, 19:12:06
If anything, overclocking is my strongest point.
And why do you think that? Explain why it does? I'll explain why it don't:
The HTT clock will calculate the memory, CPU and HyperTransport clock; having a higher or lower multiplier does not make a difference. It works on Intel's FSB interconnect, yes, because the faster you go, the more bandwidth you get (you also increase the NB clock by decreasing the multiplier.) Putting the HyperTransport link over 1000MHz is damaging for the board. It cannot sustain it for long periods.
According to your theory, it should enhance the performance of these components, but I don't see how it does that?
Well Aaron i haven't spoken about the hypertransport link but only about the fsb clock called htt on new Amd processors :winked: so what you've said in your 1st phrase is my theory or sooner the well known rule by every overclocker.

Problem... High CPU load with HDD. Please Help

Hello all,
Im stuck. Ive got a MSI KA790GX which has poor HDD access/transfer, low burst rate and very high CPU load.
As far as i know the Western Digital 640gb WD6401AALS Black should be a fast hard drive. Which according to reviews/HD Tune,
should be:-
Minimum 60mb/sec
Maximum 120mb/sec
Average 95mb/sec
Access 12ms
Burst 110mb/sec
CPU 5%
No matter what I try, i always get poor results...
My MSI KA790GX
Minimum 41mb/sec ~ 54mb/sec
Maximum 104mb/sec ~ 108mb/sec
Average 86mb/sec ~89mb/sec
Access 12ms
Burst 60mb/sec ~ 80mb/sec
CPU 26% ~ 44%!!!!!!!!
I could accept not getting the same high speed results as the review/reference, even if the burst rate sucked.
But one of the cores goes to 50%-60% load during hdd activity. Thats just crazy!!
I have tried...
IDE mode, AHCI, RAID Ready, RAID Single Disk
SATA Port 1, 2, 3, 4 + 5
Different SATA cables
Flashed bios, cleared bios, optimised defaults, failsafe defaults
Windows XP 32bit, Vista 32bit, Vista 64bit. fresh installs
MSI CD Drivers, MSI Web Drivers, AMD/ATI Web Drivers
... and combinations of.
I have also tested the WD640gb Black on another older PC, with Nvidia (55?) chipset and slower (1.9ghz x2) cpu.
Transfer rates were slightly better than my KA790GX but, Burst Rate = 115mb/sec and CPU usage = 13%.
I also tried a Seagate 1.5tb (ST31500341AS) on both PCs,
Nvidia chipset
Minimum 65mb/sec
Maximum 134mb/sec
Average 107mb/sec
Access 14ms
Burst 83mb/sec
CPU 7%
On my MSI KA790GX
Minimum 55mb/sec
Maximum 120mb/sec
Average 100mb/sec
Access 14ms
Burst 87mb/sec
CPU 33%!!!!
Could someone please please help, ive spent hours and hours on this. Its doin my head in.
I just hope its something stupid ive missed, cos i still not used my HD4850 from christmas :-(
Thanks.

Sm3K3R
Not sure how to check PIO/DMA mode on a SATA device. IDE devices show DMA enabled.
BIOS version 1.4 - 29 December 2008, and now version 1.51
Fredrik
I have Vista 64, but i did try XP32 and Vista32 and got similar poor results.
I tested HDD speed with, HD Tune 2.55 and HD Tune 3.50 trial.
No auto-start programs really, Windows clean installs + any drivers.
Quadrifoglio Verde
CPU @ default 2800mhz, All mem bios options to auto/defaults
Windows Experience Index, CPU Score = 5.3
AMD Overdrive
Integer Computation = 8220
Floating Point Computation = 5325
Memory speed = 1770
Cache Speed = 10790
System Performance = 7403
Bas
I used HDTune because I could reference to other results. Whats a better program to use?
Windows Experience Index, HDD Score = 5.9.
But I have no reference and cant be sure of cpu load.
Sepher
Bios defaults to C&C and C1E off so i have tried them. Also windows power settings, balanced/high performance.
UPDATE
Reinstalled Vista64 but loaded the AHCI driver from the disk config screen. This seems to have stopped the high cpu usage during disk activity.
HDTune with Windows Power settings @ High Performance,
Min = 52mb/sec
Max = 106mb/sec
Ave = 88mb/sec
Access = 12ms
Burst = 77mb/sec
CPU = 3.4%
HDTune with Windows Power settings @ Balanced
Min = 54mb/sec
Max = 104mb/sec
Ave = 87mb/sec
Access = 12ms
Burst = 65mb/sec
CPU = 12%
So now transfer speed is about 10% slower than reference. But burst speed is terrible.
I also used IBM Feature Tool to change the HDD AAM to 'performance mode' 254 as suggested elsewhere.
Long shot as the hdd performs ok with other hardware. same results.
Also MSI support asked me to try a newer bios, version 1.51. same results.
Anyone know what the AMD 7-Series Chipsets Disk Performance Utility does, and should i run it in Vista64?
Thanks for all the replies, hope i can sort this, not played any PC games since Quake 3 on my ti4600...
