KT3 Ultra, have to clear CMOS everyboot?

Hey guys I have a weird problem...everytime (including the first time I installed the hardware) I restart or powerdown the computer, it won't turn on again unless I reset the CMOS by the jumper. I'm thinking this is just a faulty motherboard, but any ideas?

Hi,
I just worked through a similar problem with a KT3 Ultra
MS-6380E board and an Athlon XP 2000+ processor. Every time I booted and configured the BIOS it worked fine until I cycled power. Every time I tried to turn it on - nothing, no fans or anything. I was also thinking bad motehr board, bad processor, bad BIOS, etc. I tripped over an article (I forget if it was here or on AMDs site) that discussed an issue of the motherboard not properly recognizing a processor.
Apparently the MSI board identifies the Athlon processor based on clock speed (someone can correct me here) - when my system booted it was saying I had an Athlon XP 1600+ rather than the 2000+. Anyhow, the solution requires updating the BIOS to the latest rev. What you need to do is :
1. after clearing the BIOS (this needs to be done for about an hour - not mentioned in the manual) power up your system.
2. Enter the BIOS setup and set your date and time only then exit and save your changes.
3. Go through any system install/updates you need to do (disk format, OS load, etc.).
4. Load the MSI live update utility and connet to the Internet.
5. Run the update utility and you will get a selection of results.
6. Run the BIOS update (you will need a 3.5" floppy disk).
7. Following this make sure you also have all of the lates drivers installed.
8. Now your ready for the final test! Reboot and go into the BIOS setup. Set your FSB clock to what it needs to be (in my case 133MHz), exits and save. The system should reboot without any problem now. :D
If you cant make it to #3 you have a different problem than the one I had. If thats the case - Sorry, I don't have any pointers.
Some of this should be in the manual but isn't - Issues of not recognizing the processor, how long it takes to clear BIOS, etc.
Hope this helps

970 GAMING black screen when boot on cold start, have to clear CMOS everytime

I have 970 GAMING w/ FX8320, it shows black screen when boot on cold start, have to clear CMOS everytime to enter default.
I have updated it to the up to date M11 bios. Once it boot up, it functions OK no matter whether you reboot or reset it. But after turned off a few hours (cooled down), it shows on black screen again on boot, all LED lights up OK, but I can hear the fan like keep rebooting, any idea?
PSU seasonic 430W, GPU HD7750.

In what DIMM slots did you insert your memory? I just got and at this moment building a new computer with a 970.
A horrible experience I had with my last build reminded me of it. My board was am MSI A88XM-E45. DIMM1 is blue, DIMM2 is black, DIMM3 is blue, & DIMM4 is black. When using two sticks of RAM, it says to install one on DIMM1 & the other in DIMM3 (Makes sense... After all, it's color colored that way).
Well it would not boot. I reseated every component and for HOURS tried almost everything. Finally I decided to place my two sticks of RAM in the first two DIMMS and viola!
I think I will begin this build the same way.

Do i have to clear cmos after updating bios?

hi im about to update my bios to 1.9 ... do i have to clear cmos after bios update finish? and also clearing cmos is as easy as removing the battery for a while then putting it back in right?

in my opinion Clear Cmos should be always done after flashing,
to ensure that new BIOS will operate as intended
if you need see here for guide:

MOVED: [VIA] Does MSI KT3 Ultra have a 1/5 divider?

This topic has been moved to Overclockers & Modding Corner.
[VIA] Does MSI KT3 Ultra have a 1/5 divider?

That may be possible Wonkanoby , i'm not arguing against that (where the 5 divider kicks in).
But the issue is with going from 166 and upwards divider stays at 5 forever and cause you trouble with agp & pci devices.
Maybe I was unclear with the sentense:
"Fuzzy logic up the fsb so the divider divides by 5 all the way up beyond 166 PCI/AGP frequency then follows ."
What I meant is from 166 and further upwards the divider is 5 nomatter what the fsb/mem freq. is .
This way a fsb overclock to say 190~200 gives near 40mhz 80mhz on pci bus / agp as there is no
divider 6 kicking in on Kt333 . And theese pci/agp frequencys is not any good for your equiptment .

KT3 Ultra only boots after cmos reset

I have a brand new (bought last week) KT3 Ultra v1.0 (MS-6380E) with no RAID and no BlueTooth. I've updated the BIOS to v5.7.
CPU: AMD XP 2200+ (clocked as same)
RAM: Kingston 256MB PC2700 (one stick, tried all slots, tried different stick, also tried 2 sticks at once)
PSU: ANTEC 350W +3.3=20A +5=33A (both = 180A) +12=15A -12=1A -5=1A +5SB=2A (also tried L&C 400W +3.3=28A +5=40A (both = 220W max, amps not labled) +12=17A -12=.8A -5=.3A +5SB=2A)
Cooler: CoolerMaster CP5-6J31C-01 (rated to 3000+ or more)
CPU temp: ATI mach64 PCI (also tried 2 other cards, both PCI and AGP)
D-Link PCI NIC
WD 6.4GB HDD (tried disconnecting)
ancient 4x CDRom (as 2nd master) (also tried disconnecting)
1.44 MB floppy (tried disconnecting)
No hardware changes had any effect.
Before updating bios, the system would boot only about 1/10th of the time. When it didn't boot, usually the screen would stay blank and a beep code of "longer pause, long beep, longer pause, long beep, etc." would occur. Cold booting seemed to increase likelihood of booting. Removing and reseating ram may also have increased likelihood. Putting ram in 2nd slot seemed to help.
After updating bios to v5.7, the system would never boot at all except EVERY TIME after a cmos clear. After the clear, the machine would boot and report "invalid CMOS settings" and if I pressed F2, it would accept defaults and boot OS. If I opened setup and rebooted, it would again fail to boot until another cmos jumper clear.
Lemme know what you guys think. Thanks in advance.

First, thanks for the input.
Second, please note that the cpu cooler is rated for a much faster Athlon XP than I'm using.
Third, do you recommend a specific brand of RAM for best chances of success?
Fourth, do you recommend a specific brand of PSU (if you think mine is underpowered).
Thanks in advance.

[VIA] Does MSI KT3 Ultra have a 1/5 divider?

I have a KT3 Ultra MB,
my CPU is Athlon XP 1800+(Palomino 133*11.5),
I oc it to 166*10, the system seems stable and works well
but I wonder whether PCI/AGP runs at 166/5 or 166/4
I do not want to damage my PCI/AGP/IDE devices
Can someone give me a certain answer?
thx!

KT3 Ultra 2 funny bios

I have a strange situation here. I have been running a XP1700+ palamino unlocked at 9.5x190 (1810) (max ram timings) with the original bios which was v5.5. I decided to pick up 2400+ so before installing it I flashed the bios to v5.6 which is supposed to support it. It does. Tried overclocking a little with it locked got to 2325@155fsb. Over that unstable.
So I decided to unlock the 2400+. Put back in and it was unlocked, so start going up. 12.5 x160 fsb keeping it around 2000mhz. Totally unstable.Drop fsb to155 and its stable. Try to use the 15 multiplier (stock speed) Boots at 933(7x). Try 14 mult. @666(5x) useless multipliers. Now it seems I'm being limited by the fsb, strange because 1700 would run @190fsb( everything the same except CPU and Bios).
I figured I must have got a bad Cpu.So I pull it out to see if something else may have gone bad, and put 1700 back in. Suprise!! max stable fsb 155. .
After Trying slow timings in bios and everything ,still no go. SO I flashed back to bios v5.5. Reboot we're up to 173fsb .Ran tests over and over.Stable.. Better but what happened to 190!!!
So now I put the 2400 back in unlocked and works fine up to 173fsb BUT I still have a max mult of 12.5 and max fsb 173 .
Is the bios these boards ship with different than the ones they have posted on their site?
If anyone has any info, it would be appreciated.

Thanks for the reply Maesus
I have been clearing CMOS each time. I understand that It would seem to be hardware but not sure why I can once again go higher when I flash back to older bios (not as high as original but higher than v5.6) Also with the 1700 the bios was the only change.
The other thing with the multipliers of 14 and 15 not giving the correct result also bothers me. I know it can do a 15x because it does with cpu locked but when unlocked no go. Is this a limit of the KT333 the KT3 Ultra 2 or a bug in the Bios.
One last thing there is an option 12.5/13 but as far as I can tell choosing it only give 12.5 .Is there some way to get 13x ?

Pavilion p6-2133w - Wont post/boot without clearing cmos first

I really need some advice guys. My dad just recemtly bought this computer from a friend (friend says it had no problems) which could be true.
I did a fresh format after downloading all drivers from HP, installed them all incuding the bios update (which i think is my problem) and now i have to clear cmos every single time before it will boot or even post, if i dont clear cmos the computer does turn on (fans have power) but the monitor stays black. When i do clear cmos the pc boots fine and the only thing i notice wrong is some files wont download thru IE (like adobe flash, says no internet connection when the adobe installer trys to download) and im getting constant sec.certificate display blocked errors thru IE other then that it runs fine.
So im assuming something went wrong installing the bios update, im praying somebody has or even knows what the original bios is supposed to be ? or someway i can fix it. I have since done another format and tried reinstalling the bios update and all other drivers but nothing changes
Any advice, opinions, or idea's would be greatly appreciated
Thanks in advance

KT3 Ultra Overclocking

I'm not really an overclocking buff, but if I were to get a KT3 Ultra and overclock the FSB to 166mhz, but lower the processor multiplier to approximately its rated speed, would I experience any horrible instability? Or would this be a very nice performance gain?
I'd be using 333mhz DDR for this, and as an example, say I use a 1.2ghZ athlon.
9*133=1195
7.5*166=1245
What kind of settings would I have to choose?
I would think the ram multiplier would be 1:1, but I don't understand exactly how to set the PCI and AGP dividers. What ratio would I set those at? Or are they not something you set?
Heh. Please excuse my ignorance on the subject.
Just looking for comments on the idea. )

Heh. I guess I've figured out most of the above. I know that the KT3 Ultra uses the 5:1 PCI divider when the fsb is set to 166mhz, so my question is this: Does the KT3 Ultra have the 5:2 (is that right?) AGP divider?
I'm also still interested in any issues with the overclocking I mentioned.
Thanks a lot!

Kt3 Ultra dividers

Does the KT3 Ultra have 1/5 dividers? I have read on some sites that there are none and on another site they said that the 1/5 dividers kick in at 158mhz fsb. I just want to know if this is true or not.

Yes, again. All PCI slots at 152Mhz FSB enjoy 1/5 dividers, for AGP that will be 1/2.5 . That mean only one set of divider for all PCI slots at a time. You can't set 1/4 for PCI-1, and 1/5 for PCI-2.

Can\'t boot without clearing cmos (kt3 ultra2)

Hi,
My kt3 ultra2 board won't boot up unless I clear the CMOS. I am using the following basic configuration:
Athlon 1800+ w/ alpha pal8045 heatsink
256 mb of samsung pc2700 ram
Radeon 8500LE graphics card
My psu is a 400W powmax. Here are the specs from the side of the unit:
3.3V 28A
5V 30A
12V 25A
my cpu temp peaks at 40C and the cmos battery is at 3.39V.
I am running at default settings w/ cpu fsb=100. Everytime I power up the computer (from cold start) I need to clear the CMOS. Otherwise, the D-Link lights hang on memory detection test.
Doing a soft reboot (ctrl - alt - del) once it starts up does not cause it to hang.
Either way once the thing boots it says:
CMOS/GPNV Checksum Bad
(does any one know if this could be why it's scewing up)
What could be causing this problem? Any help would be appreciated.
Thank you

I bought one of these boards about 2 weeks ago and have had terrible problems with my geforce 4 concerning exactly the same issue. Now from the support forums i have been reading, everyone seems to say different things. Either change your ram, power supply, graphics card (how would you feel if someone told you to change your geforce 4 ti4600 that you paid £300 for?)
Now lets face it, motherboards shouldn't have to be picky about components should they? Power supplies are "power supplies" at the end of the day, and yes sometimes there are good and bad makes and models, but it shouldn't stop someone from using a regular bog standard power supply. My thoughts and concerns about the KT3 Ultra 2 is that the motherboard manufacturer is in the wrong here and do not seem to be doing anything about it.
I've worked with PC's for about 4-5 years and have used many makes and models of motherboard and been able to get them working successfully every time, however the MSI KT3 Ultra 2 board is plagued with problems and it's about time someone did something about it. How would you feel if i sold you a car that would only go 10 miles and then stop working?

CMOS won't reset KT3 Ultra

The CMOS on my KT3 Ultra board will not reset. I've tried taking the battery out for over 48 hours and setting the JBAT1 to the 2-3 position. My CMOS settings will not reset.
I'm trying to reset them is because I can not get into the BIOS. When I hit delete, my screen says "Go->Setup" but it never goes into the BIOS. It continues to the MBFastTrak133 screen.
Please help me. Thanks in advance.

hi,
What keyboard are you using? I assume you never go into the BIOS, use a PS/2 keyboard instead, not USB keyboard first. YOu can use USB keyboard later after you managed to enter BIOS and to enable USB.
You can keep on hitting DEL key even at the MBFastTrak133 screen. It will still go into the BIOS after that RAID BIOS screen. Just wait for it to go off.

KT4 Ultra - correct way to clear CMOS JBAT1

Thanks to Piotr56 and Footballfan for bringing this issue out in separate threads , and pelly (although not exactly correct) and others tried to provide the answer
MSI has confirmed the printing error in the manual. "1" supposed to be the bottom pin, while "3" is the top pin. But the information for clearing CMOS is still valid.
The correct setting is :
1-2 Normal
2-3 Clear CMOS
[Socket A on top]
( )3
(|)2
[|]1 - Keep
(|)3
(|)2
[ ]1 - Clear
If you want to confirm yourself, take a close look at the board, the information is printed on the board, so as "1".
* This topic remains sticky until MSI updates the manual on the website.

Many Thanks Maesus for the quick response regarding this error.
Thanks Again.

KT3 Ultra 2R + Barton 3000+

Hi all..
Hope someone can help.
I have a KT3 Ultra 2R board with the following stats:
Athlon XP (Barton) 3000+ FSB 166 CPU
CoolerMaster HHC-001 heatpipe H/sink with 80mm fan
Antec 520W PSU
2 x 100 ATA Maxtor Viper 80Gb HDD's with 8Mb cache each in striped RAID array
Asus TI 4600 Ultra 128Mb V/card
Audigy S/card
Lite-on CD/RW
Lite-on CD/DVD
2 x 512Mb Corsair XMS 3000 DDR Ram (333 and above) with aluminium heat spreaders
Lian-Li PC70 Tower case with 6 x 80mm fans
Rounded cables throughout
Win XP + SP1
The Problem:
This system worked fine with an Athlon XP 2200 CPU and I read MSI's CPU support list and saw the KT3 Ultra 2 6380E supported the Barton XP 3000+ CPU's so I bought one. :P
At first I had trouble booting on the 5.7 version bios, with the lock ups throught the bootup process. I reset the bois to the defaults and slowly worked up the settings using the recommendations in the forums.
At the moment, the system will boot up with fast command set to normal, no agressive DDR timings, 1T command disabled, fastwrite disabled, agp read/write disabled and SDRAM set to SPD (HCLK).
My 3DMark01 & 3DMark03 scores are lower than when I had the XP 2200 CPU installed and the SiSoft sandra results are the equivalent of a Athlon 2000. MSI says the board supports the Barton 3000+, but at what cost ??? :O
The system is very unstable and and requires on average 3 boots to boot up successfully. The 3DMark03 test often locks up mid way.
Any help or the settings MSI or you used to achieve their results would be VERY helpful. Please Help... ;(

I have had a similar problem running my kt3 ultra2 (non raid) at 166 fsb. In mid april I bought a 2600+ 166 fsb athlon to upgrade my system from a 1.2 ghz athlon. I bought some new pc2700 crucial ram to go along with the processor. I had also recently bought a radeon 9700 pro in late march, and a 1.2 athlon would just be a waste of this great vid card. I had been running fine with the radeon and the 1.2 athlon with the msi 5.7 bios and 4.43 via 4-in-1's.
I battled this problem for weeks. I bought a new antec 550 watt PSU, corsair xms 3200 ram, and new antec tower case trying to find out if the problem was ram, power or heat. I should also note that turning on spread spectrum helped a little in stability. Setting it to .50% made it stable in windows and games, but the computer would not turn on if shutdown unless I cleared the cmos. No setting besides this had any effect on stability. Even conservative ram timings. I was about to buy an Asus a7n8x when I realized that I had once run my old cpu and ram at 166 fsb when I had the 5.6 bios a couple of months back. I did not keep it like that in fear of damaging the ram while overclocked.
So I reflashed to 5.6 which still supported the 2600+. That finally worked almost perfectly, although I still have to keep spread spectrum at .25% to be stable (which is odd, people say that is supposed to hurt stability). So in my situation, it was the bios that was faulty. I have had some very ramdom crashes to the desktop (3 of them) in games and one hardlock with a blank bluescreen in unreal2. This is over a span of a month. So it is not perfect. It might be the display drivers causing this, which I have recently upgraded, or I might need to back off my ram timings which are at 2-2-2-5 which this ram can handle easily at 166. 3dmark has yet to crash. Prime 95 passed when I ran it for 30 minutes. Im going to run prime 95 today and see if it will run for like 12 hours stable. Im still looking into getting a new nforce 2 mobo, however (abit or asus).
I hope this helps your situation, you should give it a try. Although, the 5.6 bios does not support the 3000+. It might still work, it will maybe just not show up as a 3000+ in the bios, but as a 2.17 Athlon XP.
I think MSI should be made aware of this possible 5.7 bios fsb instability. Why spread spectrum seems to be related in my situation, is really odd also.

MSI KT3 Ultra ARU - Can\'t install W2K !!

I've just bought my first AMD powered rig and I'm not able to install W2K pro. First let me say I'm not a computer novice and have been handling workstation/server hardware/software for years in the Intel world.
The failure happens at different places in the install, with different results.. sometimes while copying files the system freezes.. sometimes in the middle of a copy i get the BlueSOD... sometimes after copying files when booting into Windows 2000 for the first time the system just reboots to a black screen and is unable to find a boot partition... so we start over and the install deletes copied files and begins again.
KT3 Ultra ARU
AMD 2200+
Corsair CMX512-3000C2
Pri IDE M - Seagate ST313021A 13GB
Pri IDE S - Sony CDROM CDU6111-F
Sec IDE M - Asus CDRW 4012-A
Sec IDE S - none
Raid Disabled in Bios
Followed Mr.Steveo's guides for hardware installation, flashing BIOS from 5.4 (kept a copy) to 5.5. No problems.
Followed Mr.Steveo's guide for BIOS settings, using his recommendations to the letter, then after failure changed SRRAM freq: to HCLK+66 for 3000C2 ram... BUT still fails.
Additional detail - I lost my original W2KPro CD, and my copy is not bootable... so I'm creating a 2GB DOS partition and booting with a Win98 boot disk to get to the CD and running WINNT from there.
I've gone through the posts on both the AMDMB and MSI forums and seen some insightful suggestions... but nothing that exactly duplicates by problems. Hopefully one of you bright bulbs will be able to light my way. :D
When I get the BSOD I get different STOP errors:
0x0000000A IRQL_NOT_LESS_OR_EQUAL
(BIOS or Drivers using improper memory address)
0x0000001E KMODE_EXCEPTION_NOT_HANDLED
(A kernel mode process tried to execute an illegal or unknown processor instruction)
HELP !!

Back Rev'd the Bios to 5.4 but that didn't help. Back to the forums...
Bas - Thanks for reminding me of the KISS principle (Keep It Simple Stupid). I had simplified the HW but was still altering the Bios settings to where I know they should be.
WELL - I HAVE SUCCESS !!
In further research, (being new to this - remember?) I also find threads saying that I'm supposed to clear the CMOS/NVRAM using a motherboard jumper before powering up the board for the first time and after changing processors. I don't know how accurate that is - maybe someone will be kind enough to elaborate.
I've asked Mr.Steveo in the AMDMB forums if he thinks this step needs to be included in his hardware installation guide. I followed it religiously in my install and it doesn't mention doing this.
Anyway, I got the OS installed. After that, I went back into the Bios and added all suggested settings. I'm getting "2200+" in the boot screens and in the OS.
Now lets finish the install and see if we remain stable. After several days of burnin, I'll OC some to see what I can get.
Thanks Guys!!
