K8T master 2far dual processor problem

has anyone installing a second opteron had a similar problem?
diagnosis:
the system works fine with one 242 processor, prior to instaslling the second 242 processor i turn off power using the PSU switch, i install the second processor and then turn on the PSU switch at this point the cpu fans and the system fan spins up for a second and then stop. The main atx on/off switch does not now work!! however after a few minutes it does and then the fans start up at full power and keep running. There is no display signal and no sounds of the system booting. Taking the second processor out allows the system to work normally.
What the hell is going on could there be a short induced by the second processor or something, please help before the whole system gets thrown out of the seventh floor window, closely followed by me.........
AAAAAAHHHHHHHH.........SPLAT.......too late?

let me know first so i can be there to save the computer
are the cpu's identical ?
are you mounting the cpu heatsink correct ?
do you use thermal pad or paste ?
i dont knwo much about your mobo but is there any jumpers you need to change ?

Power Mac G5 dual processor problem

So I've got a Power Mac G5 Dual 1.8Ghz that I bought used that only had one processor working. When started up, the screen hangs after the gray start up screen. I figure replacing both processors would fix the problem. Having bought 2 new processors, I installed them and now the computer won't boot at all. The power light comes on but doesn't stay on, the fans spin but nothing comes up on the screen. Is this a logic board problem? Any help would be appreciated.

After changing CPUs you need to calibrate everything for one, look for Apple Service Diagnostics, ASD 2.6.3 I think, not sure which G5s that is for actually, but it's a start.
2.5.8 should work on that machine as well.

Dual Processor problem

I have been fighting with a cpu problem. my FW800 1.25 dual only works when pressure is applied to the bottom of the cpu, ie: a little "padding" between the MB and cpu around the 2 large chips. i have a sneaking suspicion the technique used to solder them to the daughter card, the ball grid array, has failed. has anyone had this issue or is this known at all?
i know the MB is good. i have tried other cpu's in my machine with no issue.
(in a related issue, ibook's suffered the same fate from this soldering on the video chip)

K8T Master FAR-2 Memory problems

Looked at a bunch of past post found some similar stuff but no luck fixing my issue. I have 2 AMD 248's @ 2.21 ghz, 1 gig of DDR 400 E/R PC3200. It is in slot1. I tried to add additional mem(2 gigs) when i do no signal to monitor, but cdrom looks like its trying to boot. Any thoughts? The power is strong btw.
i read on here that the pc3200 wont work on the 248 but it does, and i read only 2 gigs could be used. Im not to tech smart here so please and thankyou

Mixing memory is often not a very good idea.
Opterons are more able to cope with mixed memory, but it still can go wrong. Better stick to the same make/model for best performance.
i tried that also. I have 2 new sticks and one old. One new stick will work solo, but not 2 new sticks or combined 1 new and 1 old. The power supply is new and the volts are right were they should be for everything.
I put in a new AGP video card in, thinking that the old one was going bad, i have had problems with that in the past. Still no luck here though.

K8d or k8t master far?

Hello to all, looking at a server mobo what do you all think would be the better board?
k8d master far ms-9131 amd chipped
k8t master far ms-9130 via chipped
Ive looked and cant seem to find out if the k8d can use a dual core, I know the k8t is single core Dual processer mobo..
second suggest a PSU
are either boards very picky on ram pc2700
going to be the server for my shop. trouble free and last a long time!!
henrythe9th

Pay attention now!!!!
The MS-9130 is the K8T-Master-2FAR does NOT support Dual-core or new CPU's the FAR7 does, see below !
You are mixing numbers and boards here.
Let me show you the pages of the right boards:
>>K8T Master 2FAR-7<< = MS-9617 and does support ALL new CPU's, incl dual-core. Workstation board socket 940.
>>K8D Master3-133<< = MS-9161 ver2 and does support ALL new CPU's, incl dual-core. Server board socket 940.
As you are looking at the K8T Master 2FAR (MS-9130) and the K8D Master3 (MS-9161 ver1) boards, they are NOT the same and do not support the latest CPU's.
Please pay attention to this, as you are looking at the old boards, not the new ones.

K8T Master 2 FAR dual Opteron 250 Vista 64bit BIOS 1.4 only 1 CPU show!!! Help!!

Hi,
I am new to this forum but had been working on this problems for a week!
Here my system:
MSI K8t Master 2 FAR
ECC ram 2GB
Dual Opteron 250 replaced the dual Opteron 242 one week ago
BIOS upgrade to 1.4
Window Vista 64bit from Window XP Pro
The POST, Device Manager detect two new CPUs. However, there are only one CPU being utilize in task manager (yes, I have check one graph per CPU). It appear from the forum that BIOS 1.35B5? would work but I could not find it. Try to install Window XP Pro but failed (flopppy drive does not work).
Any help and suggestion would be greatly appreciated!

With BIOS 1.1 and dual Opteron 242, I have both CPU work as shown by Device manager and task manager (two CPU graphs). I can only get one CPU work since I upgrade to Opteron 250 and BIOS 1.4. Unfortunately BIOS 1.1 do not support Opteron 250.

ADM K8T Master start up problems

I have just got my self an K8T master motherboard for dual opteron, the problem that i am having is that there is no singal going to the moniter but the CPU fans spin and everthing ells seems to be working. I've tested the graphics card on other motherboards and it works find. There are no bleeps or anything i'm completely stuck on what to do any help would be great,
cheers ric

How many and what kind of Opteron's do you have installed ?
What type of RAM are you using ? (it *has* to be registered, and ECC is recommended).

Urgent : UI refresh problem on dual processor or hyper threaded machine

Hello,
I am developing an applet that displays a set of tabs to the user. Each tab contains JLists.
When user selects from any of the JList(s), all lists are updated to reflect what is still available for selection. Number of elements in the list can be as large as few hundred thousands. This all works fine on single processor machine.
However, when running same on dual processor or Intel hyperthreaded processor, lists are not updated correctly. What I meant is that, for example, if a list originally has 100 thousands elements in it, then when I select an element from it, list is updated with available elements.Assume there are only 2 thousand elements available after above selection.Everything is fine so far, but when I de-select my selection, list is suppose to be updated again with original 100 thousands elements displayed again. The real problem is list indeed gets updated properly but few elements from list are not visible on the screen. However, If I minimize the browser(as it is an applet) and restore it again, all elemnets within the list are displayed correctly. Any help will be highly appreciated.

When your JLIst refresh occurs, the items are loaded into the JList from some other Object right? Nt knowing more about your code, I can't say exactly what that would be.Yes, you are right. Let me explain in breif about the architecture of the code.
I have a class,say CatPanel, that extends from JPanel and has BorderLayout with JList (wrapped in JScrollPane) in the center.
The main GUI class controls all such CatPanels.So, when the list is to be updated, GUI class invokes a method from CatPanel with Vector of elements to be inserted as an argument. Elements are inserted using setListData method of the JList.
If I'm right, the this might explain the behavior you are seeing. In a single processor environment, the data >is not cahced and therefore everything is fine. When you go to the dual-processor machine, the threads >have their own caches and are not always in sync. When you mimize the window and restoer it, this could >trigger a resync of the cache.Is there a way to trigger such synchronization?
One thing I'm not sure about is, when you return to the 'main' list, do you still see the selected sublist or >the main list with some elements missing? When a list is updated as a result of de-selection, few elements from start of the list are not visible.
I can see all other elements by using ScrollBar. So, if there are some selections that belong to the begining portion of the list, then selected sublist is not visible.
Let me explain with following example. Assume that with current selection, I have 100 elements in the list and all of them are visible on the screen. Now as a result of de-selection, suppose now the list should contain 200 elements rather than 100 elements. So, what happens in this case is that if first 50 elements are not visible in the list then I can see blank space corresponding to first 50 elements at the start of the list followed by remaining elements. I tried overloading paint method of an element that is actually inserted into the list, but still the result is same.

Dual processor boot problems

I have had the k8t master 2 far running well with one processor, i recently installed the second and now the system wont boot at all, when you power on the psu and press the system on button the fans both case and cpu spin for a second and then shutdown. The system does not respond despite flashing bios.
I have taken taken the second processor out and the system works fine, maybe not enough power from the 480w tagan? both power cables are ssi and connected.
if you have any suggestions i would be grateful for any assistance as i am completely stumped. TIA

yes both processors are 242 1.6mghz
doesnt make much sense does it?

WARNING... K8T Master 2 FAR Dual Opteron upgrade

Anyone owning this board who has set up with one processor with a view to upgrading to dual beware.
I recently assembled a machine in MAY 2004 using one AMD 242 Opteron, the system works fine and as Opteron prices have dropped i ordered the second one. Despite the short period of time between the two orders the processors are incompatible. I include an extract from an e-mail from AMD tech support
Based on the part numbers that you provided me for your Opteron 242
processors please note that based on their revisions they are not
compatible so will not work together.
OSA242CC05 AH --> AH part # is a B3 revision
OSA242CEP5 AU --> AU part # is a CG revision
Please ensure that when putting these processors on a dual processor
motherboard both processors revision #s are the same. I have included
a link for you below with information on how to determine the revision
# for your processor.
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/30417.pdf
I am assuming that it would be fairly difficult to track down a match for the first processor so i will probabltyhave to order a third processor to match the new one which leaves one spare...for what?
I hope that this information will help to avoid you wasting money and valuable time trying to set up a basic dual opteron system.

Have you tried looking at the serial numbers through the packaging on the retail boxed version, it is difficult enough to read with the processor out of the packaging and there is nothing on the outside of the packaging to diferentiate one batch from another. Pretty pathetic considering AMD designed the 242 series for dual boards.
no i havent but i know its possible to get athlon xp with a certain number in sweden.
and if its like this it will give amd bad reputation.

Z800 dual processor Booting Problem

Hi there,
I got a Z800 dual processor , I tried to operate the motherboard with CPU 1 only without installing CPU 0. now when I turn on the device. the fan of the case spin at maximum and RAM fan doesn't spin. besides bios screen not loading. is that mean my motherboard is gone. or could be bios got corrupted.
Thanks

Labview and AMD 760 MPX Dual Processor Chipset?

Anyone have any experience with Labview on a dual processor motherboard with the AMD 760 MPX chipset [and, of course, Athlon MP 32-bit CPUs]?
Any gotchas? Any known incompatibilities?
On the hardware side, has anyone had any problems with NI-DAQ or NI-DAQmx?
Any info would be most appreciated. Thanks!
PS: Especially interested in opinions of e.g. Tyan Tiger MPX -vs- ASUS A7M266-D [or any other boards you're familiar with]. Thanks again!

It's years I use 6533 high speed digital i/o making 2mhz output without problems on any hardware.
Today I'm trying to use a Tyan Tiger MPX (double AMD)and .....it doesn't work at all. It's surely a problem with the pci bus, dma and bus master. The total speed is 200KB/sec instead of the desired 2MB/sec. I tryied more than one serial number so the problem is a motherboard's design problem.
I dont use labview but only nidaq drivers and C language.
Now I'm changing the motherboard...at least until someone explain me how to work around the problem.
No problems with MSI and Intel motherboards.

K8T Master & Nvidia Quadro4 NVS 400??

I was just wondering if anyone here is using an Nvidia Quadro4 NVS 400 (4 display PCI video card) with the K8T Master-2 FAR motherboard?? After having nothing but problems trying to get two dual-head video cards to work on this mobo (one AGP, 1 PCI) I've decided to maybe try a single quad-display PCI card, but was hoping for some input before I make any purchases.
Thanks in advance,
Bill

Hi and thanks for the reply,
I did use a different switch and it did the same thing.
I haven't tried a higher wattage one but I doubt it needs that much juice,
especially without anything plugged , ie. hdd, cdrom...

K8T Master 2 FAR; Hard Drive Questions About

Greetings!
I just got off the Google bus and stubbed my toe on your doorstep. What luck!
I have many questions, and it's getting harder to find answers for a mainboard that's not being sold "new" anymore. I did see some other topics that go along lines similar to my own, but I figured it would be a good idea to open a new thread with my specific questions.
I have decided to split my questions into three parts. This is part one, "hard drive" questions.
HARD DRIVE RELATED:
Western Digital recently announced a new high-capacity SATA Raptor drive, with 150 GB of storage:
1) Can I mount two of them into my K8T Master 2 FAR system and "hardware stripe" them for Windows/XP?
....1A) If yes, is there a minimum recommended BIOS that I should be running?
....1B) If no, then would it be feasibile to "software stripe" them in Windows/XP Pro?
If I decide to proceed, I will be well-prepared to accept the risk of data loss that would occur if one drive were to crash.
I currently run my system with a removable SATA drive caddy for my system drive. This makes it easy to swap OS's by swapping hard drives without opening my CPU case. If I go with a dual-striped SATA drive arrangement and two Raptors, then I'll replace that removable caddy with a unit that can accomodate two SATA drives.
....1C) Once in a blue moon, I get a BSOD after having swapped SATA drives. It happens when I first boot Windows/XP after having run Linux. Hot-swappable claims notwithstanding, I always swap drives while the system is powered down, although I don't typically shut off the hardware switch at the power power supply. Are there any known issues or reports of other people having similar occurrences?
I also run some IDE devices for data and archival purposes. My system is typically set up as follows:
CH 0/0 - Data drive
CH 0/1 - DVD burner
CH 1/0 - Data drive
CH 1/1 - Data drive
Recently, my system stopped "seeing" any hard drives on CH 1 drive 1. Known good drives won't show up in the BIOS, and auto-detect doesn't "see" a drive in that position. I have tried more than one drive, and the problem stays on that channel and position. I swapped cables with a known good cable, and the problem stays on that channel and position. For the time being, I have disconnected one of the data drives...but I'd really like to resolve this issue if possible.
....1D) Are there any known problems or issues with "disappearing IDE devices" in the K8T Master 2 FAR?
Thanks in advance!

Can't say, this is the first time I hear about SATA caddies....
Maybe a bad contact or so?
Sata is pretty sensitive to connection problems, or even folded cables for that matter...

What is causing a PowerMac G5/2.3GHz Dual Processor sudden abrupt shutdowns

Hi all
I am posting in hope that someone out there can help me solve this very puzzling problem.
The machine: A PowerMac dual processor G5/2.3GHz (early 2005). 1.5G RAM. 250G HD. SuperDrive. Radeon 9650.
The problem: When under some load, this machine will suddenly and abruptly shutdown as though someone pulled the power cord. There is no warning. Just a soft click, and it powers off. The machine can be manually restarted after the sudden shutdown with no problems.
This problem is very replicable. (eg go to a particular website, play an embedded video, and boom, the machine shutsdown. Each and every time.) It was replicated at an Apple Store and at two Apple Authorized Service Providers.
System.log said "PMU forced shutdown, cause = -122"
Before the sudden shutdown, the machine seemed to be operating normally. The fans did not noticeably speed up. Activity Monitor showed no more than 50% CPU activity for each CPU. Temperature on both CPU was around at 70C before the sudden shutdown. Temperature and activity on both CPU goes up and down in tendem.
If I use the Energy Saver system preference to change "Processor performance" to "Reduced", the problem goes away. (As measured by going to the same website and playing the same video. Even playing 5 videos simultaneously did not cause a sudden shutdown.)
What have I done #1: I have reformat the hard drive with a 7-pass security wipe, followed by a clean-install of Tiger which was then brought up-to-date using Software Update. I then installed Safari 4.0.3. No other software is on the machine except Tiger and Safari. (Later installed Hardware Monitor to get me a handle on the temperatures.) The problem persisted.
What have I done #2: I then installed a new PRAM battery and reset PMU using the switch on the motherboard. Resetting the PMU also resetted the PRAM. The problem persisted.
What have I done #3: I then took the machine to an Apple Store. They found that they can replicate the problem easily. But, after 3 days of running the Apple Service Diagnostic, the diagnostic software didn't find any problem. They also did a thermal re-calibration. That didn't help either. Without an error code from the diagnostic software, the only "solution" the Apple Genius offered was to start swapping CPU, power supply and mother board at my expense. And even then, he has no idea which component to start swapping first. (Two independent Apple Authorized Service Providers offered the same non-diagnosis and roughly the same "solution".)
Has anyone encountered such a problem before? What was the solution?
How about an educated guess as to what's wrong?
I want to, if possible, and if reasonable, repair this machine.
Thanks in advance.
Lara

This sounds almost exactly like the problem I have. My G5 is also an Early 05 2.3G. I tried every tip I found on the forums from UPS vs. wall socket to stock RAM vs. 3rd party to booting from external HDs, etc.. I currently have 10.5.8 on it and it's running using the "Reduced" processor setting in Energy Saver prefs.
I have also made a trip to The Apple Store where the AS folks ran their diagnostics but were usable to replicate my problem. I understand they "can't fix it if it ain't broke".
Aside from the "Reduced" setting work-around has ANYONE actually solved this problem definitively? Although I have no interest in spending $1000 to fix this, I can't imagine disposing of it on Ebay.
Assuming this is a hardware issue, this would mark the first insurmountable failure of any of the 10 or so Macs I have owned.
Anyone? Anyone?
