Hi there,

I create a sort of Opteron&FX trouble guide here.

This only applies to the K8T-Master series as because I have this board, but can work for other boards too.
The part at the end is for K8N-Master series, I add info when I see solutions.

Ok, here we start:

Memory

The board MUST be used with REG-ECC-DDR or it will NOT work.
The CPU is very picky about the ram you use, it's best to use MSI tested memory.
Because the memory-controller is internal in the CPU it's NOT the boards fault if a certain brand doesn't work, it will fail on other brands of boards too.
See the other Sticky for MSI tested memory.

The memory should be inserted in the folowing manor:

1 stick - slot 1 Single channel
2 stick - slot 1&2 for dual channel or 1&3 for single channel.
4 stick - all slots dual channel.

I think it's best if you allway's use the same memory sticks, at least for Dual-Channel operation!
So 2 the same in slot 1&2 and 2 the same in slot 3&4, do not mix!

Allway's check the memory with Memtest86 to be sure it doesn't have problems.

If you have 4GB memory installed (MS-9130 board), it won't report all of them.
This is a BIOS issue as far as I know, MSI promised to look into this matter, as the BIOS lacks memory remapping to above 4GB.

FX not running full speed

Update the BIOS to version 1.10 or above, then it will run just fine.
The latest version at the moment is 1.3B5 and can be gotten from the MSI download pages.
For most people versions 1.10 or 1.20 are sufficient, a new BIOS will probably released at the end of Sept 2005.

MSI Coolers or other ones

They are loud the first minute, after that they drop to about 2200RPM.
I think you must turn on smart-fan-monitor for this.

If you want to use a different type of cooler:

CPU coolers for the K8T-Master type of boards that fit.
The coolers you can use instead of the standard MSI coolers are the ones for Intel Xeon 604 type with screws.
An example for rackmount can be found here:

Thermaltake 1U CPU cooler
Anyway, I tested this cooler, it does the job, but only after I sort of turned it into a Sallman cooler.
Ergo, I have bend all the plates as far as I could to create a wafer of it.
I also putted 2xPC-2700 REG-ECC memory in slot 3+4, because 1+2 will make the CPU overheat in a 1U case.
I also noticed that the BIOS does turn the heat up a lot, Linux made it run at about 45-47C, but after rebooting into the BIOS
I saw it going up stadily to about 65C, ergo, do not trust the BIOS reading much, as e.g. Linux runs the CPU a lot cooler then the BIOS does.
Why? No clue, as I tested 1 FX-51 and 1 Opteron 240, both went way nuts on temps in the BIOS, even the heatsink was very hot.
After running Linux for 30 minutes, then check the BIOS, only 45C and instantly going up a lot.
Tested Linux is Debian 3.1 64-bit.

Harddisk led doesn't go out

I have that too, a newer BIOS didn't fix it, don't know why (yet).
It works normal with 2 CPU's, but stay on with 1 CPU :shocking:
Try every BIOS until you have the right one where it does work :biggthumbsdown:

Core-Center-Pro

Download the latest version from the MSI website.
On my Opteron serveral things don't work like:

FSB x Multiplier
CPU-Fan-speed after it dropped below 2500RPM
(Has been reported to MSI, no answer yet)

Powersupply

Make sure you have enough power!!!!
Most DUAL-Rail 12V PSU's fail because they are not able to deliver enough.
Find a Powersupply like the Enermax 465 - 33A@12V single line or the OCZ 450 12U 26A@12V (or a higher model as long as it's single rail)
Check the manual very carefull on this part, you can use a normal 20pin PSU BUT you must connect the connector to the section that is NOT covered by the sticker!
See MANUAL!!!!!
The 4pin 12V connector goes on the 8pin connector, NOT on the one that is near the AGP slot!!!!
What ever you do, DO NOT use JPWR2 at all!!!

Keyboard
When numlock is turned on in Windows, after shutdown the numlock stay on.
(Can't find a BIOS setting to change this)

BIOS/Windows performance settings

First a warning, DO NOT ATTEMPT to flash any of the 1.4x BIOS versions!!!! It will kill the BIOS Chip!!!!

I have been playing with a few settings, these might give the maximum performance.
Load Optimised Settings first.

Then change:

AGP 1WS Write disable
AGP 1WS Read disable
Spread Spectrum disable
Chipkill disable
DBI disable
PCI 0WS enable
PCI Post enable
PCI Delay enable

Registry entries Win2000 (might work for XP too:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"LargeSystemCache"=dword:00000001 (doesn't seem to work with just 256MB)
"SecondLevelDataCache"=dword:00000400

WinXP with SP2
SP2 seems to cause a lot of trouble.
But there is a quick solution.
Go into the boot.ini and replace the /NoExecute=OptIn to /Execute
This will turn of the 64bit extensions needed for DEP and turn off DEP as well.
After this SP2 works like it should be.

K8T-Master-2-FAR7 (MS-9617)
BIOS 1.10 and below have AGP-videocard problems, if it won't boot, put a PCI videocard in and flash to BIOS 1.12 (worked for me)
My FX-51 CPU doesn't work on the board, problem has been reported to MSI, running an Opteron 240 at this stage.
The BIOS doesn't safe well, the clock changes at the first start, no clue why yet.
Putting a single CPU in will give all sorts of troubles, MSI is working on a new BIOS with new CPU-code to solve this.
With 2 Opterons in, it should work just fine with BIOS 1.12.

K8N-Master Second CPU no boot problem
(Thanks to Diranged for finding the solution)
I found out recently that the board comes with a Voltage Check circuit that makes sure that CPU1 and CPU2 have the same voltage. If they don't, the system powers off after about 1 second. If the board is in any way changing the voltage of the CPU, it changes the CPU1 voltage first -- which causes a trip situation in the circuitry and the board shuts off.
It can be reproduced by going into the BIOS and manually setting the Hammer FID/VID settings. Once you reboot, the system will not stay on. Or, you can try using "RMClock" to manually set the voltage in Windows and your system will shut off instantly.
As it turns out, there is a re-work on the board that is required to make the feature work (they basically disable the voltage check circuitry) -- but you have to send your board in to them. Once they send your board back, Cool'n'Quiet on 2 CPUs will work, and your system should be fine..


That's about it for now, when I see more troubles I alter the post. :beerchug:

Anyone knows what happens if you use 4 sticks with 1 CPU?
64 FX 51
Currently using four sticks of KVR400X72RC3A/512

(SDRAM-DDR, 2.6V, CL3, 400mil, TSOP, Double-Sided, Gold)

It is registered ECC. But here is what I didn't think of. I haven't put together a PC for a couple of years, and I had no idea if this is dual channel or single channel, and from the way my 3dMark scores are looking it seems as if it must be single channel to me. It is only Marking at 4900 or so. I suppose I could try it in slots one and two, if I am reading the manual correctly though it should be 128 bit with all four sticks in. Any way I can find out if it is running dual channel or single channel? Or should I buy different memory? What do you all think?

Why use 3D Mark as a measure memory preformance ?
3D Mark 2003 isn't affected by the system anyway, it's a pure GPU test.
It resaults the same on a PII350 and on a P43.0 with the same VGA card.


Use SANDRA memory bandwidth to test memory bandwidth, your RAM should be running at 333MHz dual channel giving a mak bandwidth of 5333MB/S.
It should be pretty close to that on the FX/opteron because of the efficient memory controller, but not exactly 5333. Anything above 2666MB/S (~2700) means your in dual channel - as it should be with 4 sticks.

Actually, that's not true. People tend to call it "dual channel" because the performance scales to twice as the memory bus data width has been increased to 128 bits wide. Just like you used to have to put 2 32 bit dimms in a Pentium board, you do the same thing for an Opteron. But since we're better programmers now (joke), you can opt to leave a dimm out and fall back to 64 bit wide mode for easier user compatibility.

Trust me, I've got datasheets, and it doesn't say dual channel anywhere. AMD doesn't even us the term "channel."

Cool, I will try that BIOS mod. I have been really mad for this past 'week'. I have been working on this FX51, with 2 Gigs of CL3 Ecc Kingston (I mean Samsung!?!?!) , like 4 fans in this thing. I ran a few different benchmarks, and then I was using CPU-Z that told me that I was running 9x multiplier. I tried turning up the Freq. to 220 (that works) making the chip run at 1.99Mhz. But that of course isn't good enough for me. So I will download the new 'Beta' BIOS for monday, and hope for the best!

I can't wait to get er' up and running at full speed!

I'll keep everyone posted.

P.s. I also am having problems with Windows XP 64-Bit Extended, on the RAID Controller and Audio Drivers. Any Info, or places where I can get some Drivers (Beta, Alpha, or Source Code?)

BAS. Do you just love the punishment or do you use what seems to be a server board for something practical?

It's not only a server board.....
Have you ever looked at the spec's?
No AMD64 board can compete with these type of board.....

Thought I would post to the sticky thread...

2cpu has a whole thread dedicated to the master2-far it's got lots of valuble info:

http://forums.2cpu.com/showindex.php?threadid=43961

Here is my OCZ thread about the master2 far, got a fair amount of relevant info :

http://www.bleedinedge.com/forum/showindex.php?t=2650&page=1&pp=15

And this thread is also pretty usefull (in this board)

Aloha,
one important question.
Is there any chance to work a (or two) 90nm tech CPU(s) (eg. DualCore) in this mb?

Hi,
I have a computer with a fx51 on a msi master far 1 mobo. I want to clock the cpu to 2.4 ghz by changing the multiple to 12 in bios. But the multiple always resets back to 11 when rebooting the system.

any sugestions or ideas...

Sorry, you can't overclock with the K8T-Master-1/2FAR(7), they are not designed for that.
If you want to overclock, use the K8N-Master, that one has the stuff to do it.
As for Dual-core CPU's, they are NOT supported on the K8T-Master-2FAR....only the K8N-Master and the K8T-Master-2FAR7 support those.
