K7N2 Delta reboot by itself... (NO POST)

Hi folks,
Last month I bought a K7N2 and since than it sudenly reeboot by itself...
The best way to simulate this problem is when I play 3d games such as Need for Speed2 Hot Pursuit, but the pc can also reeboot even when you are reading the news on the web or when the system is idle.
Temperature is always ok. Even so, it can also reboot at 38°C.
I've got a doubt on the 12 volts. The bios reads 11,55V when it start up. Can this be the problem? Is this 11,55V ok for the machine? Anyway, I've already tryed other 3 power supplies and all of them shows 11,55V for the bios.
OK, I've already get the bios update to 5.8 but this problem used to happen with the preview version of it too.
If you have any ideia, please post it, please

Hi dude,
I've just replaced my psu again (this morning at the store I bought the first one), so I'm sure this is not the problem.
But the bios still has 11,55V stead of 12v or somewhat close to this value. PC Alert shows 11,55 too, but it may go down to 11,34 when I play 3D games as NFS2HP.
My multimeter reads 11,98 on the psu. Strange, isn't it!?!?
Thanks!

K7N2 delta reboot frequently

Hello ALL
I have a K7N2 delta with arhlon 2600+ 256Mo.
My problem is the following :
My pc reboots frequently since I have upgraded the BIOS (Ver 5.60) and changed my graphic card.
The temperature of the CPU gets up to 80°c....I suppose it is the reason why my PC reboots...But I dont know why the temperature is so high....
Can someone help me please....

Hello,
Welcome to the forum, please start by reading MOAN GUIDE That temp is way to high, sounds like your cooler is not installed properly read CPU Install Guide and Artic Silver

[nforce] K7N2 Delta, having massive lock-ups / random reboots.

Hi all, it's been a while since I last needed your wisdom. Anyway, a couple of days ago my machine began to randomly reboot on me, so I went about trying to figure out what is causing the problem. I've cycled out my PSU, my drives, changed BIOS settings, so on and so forth, and it's still happening. System Specs follow:
MSI K7N2 Delta Mobo
Athlon 2800+ Processor
512 x 2 Kingston ValuRAM PC3200
Generic PSU : 3.3v : 28a, 5v: 30a
EVGA Nvidia Geforce 5950 Ultra 256 MB
Seagate 200GB 7200 RPM Hard drive
Lite-on DVD/CDRW Combo burner
Any ideas? I've been dismantling this thing and rebuilding it over and over for about a week now, and nothing has changed. I get the reboots all the time, graphic-intensive and not. I've even had the machine freeze up in the BIOS menu before. Help me please!!!

Alright, thanks a lot guys for all your help!
Hi there..
I'm not sure if you have fixed the problem or not.....but i have the same board and my pc reboot maybe one or two times a day...
and i'm sure it is my Ram, and i also use 2x512mb Kingston Value pc3200
i have tried with 2x512mb crucial pc3200 from my other pc and then there is no problem...
ps. I haven't been writing in english for a long time.

D-Brackett Lights are 1-Red 2-Red 3-Green 4-Green (Processor Damaged or Not Installed Properly).
I installed the Processor onto a MSI KT4AV (Everything Else same specs) and it booted and ran the OS and several apps without a problem. I re-seated it on the K7N2 Board several times without getting past this error on the D-Bracket.
I have read several of the postings and have checked, and re-checked for possible shorts on the MB. I even removed the brass Mounting screws and replaced them with plastic.
I have also checked (and tried changing) the J10 and J11 Jumpers.
All Peripherals have been removed except for the RAM, Video and D-Brackett. And I still am not even POSTing. I have tried booting without a Video card installed as well (still same error message on the D-Bracket).
My Question:
Can you tell me anything else to try before I RMA this MB?
Thanks,
IBskweak

Bonz,
Thanks for the quick response.
I went and tracked down the following RAM this morning to try:
Mushkin 2x256MB PC3200 Level II Black Line
Corsair 1x512MB PC3200 CL2.5 -L FSB @444MHz 8-2-2-2.5 @ 2.7MHz
Crucial 2x256MB PC3200 HiPerf -ILSR w/IGP 1:1 DC 5-2-2-2
Even after trying each set I got the same results as before.
Still won't even POST. Same results as original message
Unless someone else has a good idea, I'm going to RMA the two MBs that I purchased.

I have k7n2 delta L --6570--amdxp-2500-512 mb pc3200 ram. powmax 400w power .ati 9600 all in wonder. I swapped all parts to a better case to fit a certain location and the system will not post at all. the diagnostic d-bracket has number 1 and 4 in red while 2 and 3 are green. the book only tells me that the processor is initializing with a note saying this will show information regarding the processor (like brand name, system bus. etc. but nothing will show on the monitor. everything was working fine before the swap. i have checked everything i can think of. i would appreciate some advise. sorry if i haven't posted all the proper requrements and spec's. thanks. paul k.

i reset the memory and cpu and video card. i think i disconnected everything in the case a couple of times to make sure it wasn't a simple blunder. nothing! i have a friend that wants to try look at it i may do that. also tomorrow i will try to post all my info like the rest of you guys have done. i'll give it a try anyway. also i done the other things you mentioned, i forgot what the questions were. you can't see the post info that i am replying to keep checking so i can answer properly and i forget things.

dram frequency should be 1:1, particularly so if having problems like so
fsb = 166. Also want memory bus at 166 Mhz, means ddr = 333
see if that gets rid of reboots
I have changed frequency to 1:1.......and i am actually running in dual channel now....
my ram are running 166 with timmings 2.5 - 3 - 3 - 7

my ram was running 200 with timming 3 - 3 - 3 - 8

K7N2 Delta Post Bios Boot faliure

I just bought the motherboard set it all up and powered it on and all the fans spin up but make a rapid speeding up and slowing down noise. i took the motherboard back to the shop and they replaced it and tested my new one in shop and it worked fine. i took it home put the processor ram and gfx card in and the same problem happened again. on the d-bracket it says its a Processor problem ive tried another processor in it and got the same problem. also the Led's on the d-bracket flash on and off instead of being constantly on.
i am using 512mb Corsair 3200 400mhz Platinum Ram, AMD Athlon XP 2400+ also tried 1700+ to no avail and a Radeon 9700pro. i dont understand what could be wrong as it worked fine in the shop with their ram and 1700+ cpu ;( i could just cry. i have also tried swapping out the power supply with another one :O any help into this problem would be greatly appriciated.

Thepower supply im using is a Q Tec 550watt Gold it is a really good power supply the only thing i could check is swap the memory around the slots and take the motherboard out the chassis and see if it works then...could be a short inside the case :'(. i have cleared the cmos memory and set it to safe 100mhz fsb.i was under the imprestion that the MSI K7N2 Delta was a good mobo i must of been mistaken :'(. what make of ram do you guys use and where could i get some :D BTW i live in th UK (England). im not overclocking anything either :]

K7N2 Delta /no post, blank screen/

Hello everyone!
I'm experiencing the same problems as the ones described in:
http://www.short-media.com/forum/showthread.php?t=17501
The D-Bracket shows: green, green, red,red (DEcompressing BIOS image...)
I have nearly the same mobo, MSI K7N2 delta 2 lsr, but there is no J10 jumper on this one. I heard that starting the computer with the Insert button pressed should do the same (safe mode), but it didn't work for me.
I tried to clear CMOS (with the jumper and with the battery as well)
I tried other video cards, memories,... I swapped all parts of the computer.
I really don't know what to do.
Could you help me?

I thought I had to press Insert continuously while turning on the computer
normally thats what you do! let us know how you get on, you could still run into problems yet!
good luck!

K7N2 Delta-L deteriorating cmos resets

Hi
System info :
K7N2 Delta-L mobo
XP2500 Barton
2 x 256mb Samsung (Korean) PC3200
Coolermaster CP5-8JD1F-0L hsf
PNY ti4200 128mb
Maxtor 40g 7,200 hd
Pioneer DVD
LG CD-RW
2 x 80mm case fans
1st psu 400w generic
2nd psu Thermaltake 420w
All installed with first psu, and XP pro. Running no problems. Tested cpu at 11 x 200 (not straight off, gradually built up to it, watching for stability or temp problems), was running fine at stock voltages, ran 3d mark 2001 successfully. Backed things off to 10.5 x 200 to ensure stability. Re-ran 3dmark 2001, then ran prime95 overnight (8+ hours), with no problems at all. Temperatures were fine, I set the cpu temperature alarm well into the safe side in the bios (55deg). The highest cpu temperature PC Alert displayed, was 29 deg.
Updated the bios to 5.3, rebooted and checked the settings in the bios, went back into XP, no probs, re-ran 3dmark, went online, and started to play Dark Age of Camelot. After somewhere around 2 - 3 hours, the display started to "stutter", and the mouse movement became erratic. I logged off, checked PC Alert temps, all was fine, but 12v line had gone down to 11.56v. Rebooted to check the volts in the bios. They were down too, also the blue line selector had acquired a mind of its own, randomly headed anywhere when next item was selected, so I switched off, and guessing the psu to be maybe a bit inadequate, ordered the Thermaltake 420w to replace the 400w generic.
The Thermaltake arrives, install and fire up, after clearing the cmos to start again, and set up with basics. Voltages were all very satisfactory. In the meantime I had checked the cpu seating and thermal compound, and there had been no problems, and I also took the heatsink off the ti4200 to check thermal compound, cleaned and re-applied (as I did with the cpu).
On the fire up into XP, got a bsod with file corruption notice. Booted into Me install cd, formatted the drive, loaded smartdrv, and started a new XP install. The system locked up after a successful install, about 2 minutes into the worktop (went to use windows explorer to access drivers, etc., and it froze). Had to use the reset button, and it would not post. Cleared the cmos, and it posted. Reflashed the bios to 5.2 that was on the distribution cd just in case.
Since then, it has been a catalogue of failed installs, lockups and increasingly difficult clearing of the cmos. It is now at the point that a cmos clear does nothing (with the other pins at 100 and safe mode), and it fails to post. I get to the 3 lights flashing on the keyboard, and that is it.
I removed the board from the case, just in case I had hallucinated and missed a riser or something, but the risers were in the right place, and each had a fibre washer on top. Tried booting with the board out of the system, with just the cpu/hsf/memory/graphics, with no joy, also tried with a Gf 4 mx 440, and also no joy.
In retrospect, I don't think the 400w psu was too bad to drive the system, but it was worth being cautious - it has driven another system with no problems since. The cpu was performing great, as was the memory. There was no problem with the hsf or agp card. Memory was tried single stick in each memory slot (and all of it had flown through 3dmark and prime95 previously).
I am tempted to suspect something is adrift to do with the Athlon powersaving mode that has been mentioned in these forums. Other than that, there was something a bit weak on the mobo, and it has slowly bitten the dust.
Any suggestions gratefully received.

PS.
The case is one of those Superflower Midi towers, with good case volume. Airflow was quite nice with the 2 extra fans, one at front pulling in, the other at rear extracting.
The fan on top of the heatsink, is the standard Coolermaster, which overhangs the heatsink either side, with the bonus of blowing a nice airflow over the northbridge.
The 400w generic psu had 2 fans, which were also pulling a fair airflow through the case. I didn't get any indications of anything even aproaching overheating.

K7n2 delta-L o/c advise (for a newbie)

I have a K7N2 Delta-L, a Athlon XP 2500+ barton, 512 ram (2x256 Kingston/Infineon RAM, CAS 3, dual chanel) and a ATI radeon 3600SE GC.
I have set the bios settings to "High Performance" (preset in the bios), but someone told me that with a Nforce2 chipset, those settings are not "synchronised" (I understand: not optimized). So my question is: how should I set the bios manually to get a better o/c than the automatic "High Performance" settings ?
I don't want to make my motherboard overheat, and I would like to keep it stable ( I enjoy the stability of my MSI). Could someone suggest me a few tweak for the bios (or with Nvidia System utility) to make my system faster, but safely !
Thank you very much !
PS: Here are the settings someone suggested me on MSI France forum, but it made my PC crash seriously, and I could not even reboot... had to cleat the CMOS !
System performances => manual
cpu fsb clock => 200
cpu interface => high performances
FSB/RAM ratio => 1/1
memory timings => manual => 11/3/3/2.5
FSB et AGP spectrum => disabled
AGP aperture size => 128
Frequency/voltage control => DRAM => 2.8 volt
Cpu ratio => 10
Vcore => a little bit more than the default setting

which you already do.
But these settings made my PC crashed... I could not reboot and had to clear the cmos... the problem was with the processor, I think.

vdimm 2.8v is a bit high.
is it neccessary to have it that high ?
I don't undestand if it is necessary... usually I prefer using low voltage to keep my PC cooler. I would prefer "under-volt" my CPU rather than "over-volt" it.

HD or Booting problem on MSI K7N2 Delta 2 Platinum

Hi all,
Ive a weird issue which i cant figure out myself. I've 2 HD's..lets call them A and B where A = 60Gb (Master) and B = 80Gb (Slave)
It's is like this:
A and B are connected to the primary IDE-slot. A will boot when set as Master and B wont start booting when set as Slave mode (i mean, it wont show/appear in the first hardware (detection) bootscreen of yer BIOS where it says its present or the so called POST-screen), but if I set B as Master only (A turned off) it will boot.
What also happens is if I disconnect the power of drive B..drive A will boot..and while OS is loaded...I turn on the powercable from drive B and reboot..suddenly out of the blue it detects both HD's and reboots like it should do normally...but when i reboot from than..the same thing happens again..(it wont recognize B anymore)
Sumtime it regonizes both drives and sumtime it just won't and sumtimes just 1 drive..
Another thing, when it won't recognize one or sumtime both drives...the POST-screen gets stuck at the name and version of the BIOS...and where it says: 'detecting IDE drives...' when it is at this stage..and I press on the DEL-key for example..it's loading damn too slow..I've to wait about 10min before it enters the BIOS-setup..
I am 100% sure I set the jumper correctly for Master or Slave mode on my HD..I know there's sumthing wrong..but don't know where...Ive changed the jumper with a new one ..switched IDE-cables...switched HD's (set B as Master and A as Slave and vice versa, knowing there is no active partition on B..but only to check if it recognizes the drive)..in all cases..the BIOS settings are set as default!
any1 can help me out with this?
It worked smoothly on my system till i noticed my second MEM bank of my mobo broke (Asus A7N8X-E)..so i had to change it quickly (and went to the store with my warranty to fix this board..it was only 3 months old) ..since I've seen/had enough Asus mobo's in my life I went this time for an MSI which looks better in my opinion...so now i have an MSI K7N2 Delta 2 Platinum..it works fine...except that HD issue mentioned above
any help would be appreciated..thnx in advance!
cheers!

Hi,
I've done that already several times...it doesnt work..any other suggestions?
Now I can boot normally when I disconnect the power of the 2nd HD (or just any HD)...when the os is loaded...I turn back on the power of the 2nd drive and reboot...than it will run/boot/restart etc..normally...this is the only workaround I have at the moment...this only works when the system is turned a long time...
My power supply is 400W..so I don't think Ive any prob with that
cheers

K7N2 Delta ILSR won't boot from FDD or HD

I have a serious problem with my new K7N2 delta ILSR based computer.
My machine is
K7N2 delta ILSR 400W
3.3/25 5/32 12/15 V/A PSU
512+256 MB A-data 3200 ram
Athlon XP2500+
BTC 48x24x48 Combo
100 mb Zip int. -disabled
120 GB Seagate barracuda SATA-disabled
120 GB Seagate Barracuda parallel
Triplex parasouls ATI 9600PRO 128MB
The machine POST's normally with all 4 lights doing what they should.
The Promise BIOS can detect the SATA drive correctly but when an attempt is made to write the array an error- 'error modifying array- system is going to reboot- press any key to reboot>" is given.
The M/B BIOS detects the FDD and Seagate Parallel drives correctly but when a correctly formatted XP boot disc (or Mandrake Linux or Caldera DR-DOS) is placed in the floppy drive a "no system disk" error is given.
When you F6 to install RAID drivers in the Windows XP install and the screen comes up where you are prompted to insert the floppy there is no mass storage device detected.
I purchased a new FDD and it gives precisely the same error as the original.
I installed the parallel Seagate in another system and installed and activated windows XP on it. After re-installing it in the K7N2 system I was disappointed to discover that it will not boot off the hard drive. When you boot from the XP CD the machine locks up. (Disconnecting the HD it will boot normally)
This is a real puzzle as it is possible to format the hard drive using Max Blast3- the maxtor disk utility which is based ( as is the Seagate Seatools utility) on Caldera DR-DOS). And I can't see why it should boot from a CD-ROM and not from any other correctly formatted boot disk.
I suspect a problem in either the (South?) bridge that controls the peripherals or the BIOS. I am at a loss how to re-flash the BIOS with out the use of the floppy drive- unless this can be done from a CD-ROM.
The PSU is not being strained and nForce list both RAM sticks as OK.

The Fd light behaves normally. i.e. lights up when the drive is being accessed.
has anybody else noted that the FDD is B by default- That the cables have a few wires twisted like the wires between the first and second plugs on the old cables?
The IDE 80 wire(counted!) is long end in the board- my plugs are all 3 black. You can't put them in the wrong way becaue of the centre key.
All the stands are plastic except for two brass ones that are in the centre of the board that go to circular mount pads. That is how the case came and I thought it was a design feature.
The thing I find most puzzleing is that i can boot a caldera based system that finds everything including the floppy- and read it- (provided you call it drive B!) yet naything DOS based won't go- I have this feeling that it has a screwed up DOS call that is not looking in the right disk sector for NTldr or whatever to boot. I think this is a bios problem- but I am not sure how to find out when you can't boot from the FDD.
My brother has talked to some tech friends and there word is that this is a weird one- probably a dud board RTS.

How to reduce from 5º to 8ºC CPU Temp on your MSI K7N2 Delta!

I've installed this tweak last week and it is working very stable since then. It decreased my Idle CPU Temp from 42º to 36º and Overload from 54º to 48º:
Just go: http://forums.pcper.com/showindex.php?t=280137
AMD ATHLON XP 2600+ 12.5x333mhz 1.65V ~OC 11.5x400mhz 1.55V
Thermaltake Volcano 9
MSI K7N2 Delta L
MSI GF4 4200-8X graphics Card
160GB Maxtor HDD 7200rpm
768MB Samsung DDR3200
LG 48x24x48x/16x CDROM/DVD Reader
Dual Fan 450W Troni Power Suppy

It seems that the link to the tweak is broken, I've found another one:
http://ftp://ftp.vector.co.jp/pack/win95/hardware/other/wpcre14.exe
This is what the article say:
Just tried it for the first time..It works GREAT
My idle temps are now 26c, down from 34c. That's 8C. I can have Winamp, IE and messenger running and CPU temps don't get by 29c. Once i fire up, SETI though...I get back my regular Load temps at 39c.
Some of you probably know about it, already....here's for thousand others that don't.
This tweak can drop your idle CPU temps down as much as 8c, maybe more...depending on your system.
First thing you need to do is download WPCRSET & WPCREDIT.
They're both in this zip.
- Extract to a directory.
- Run "INSTDD.EXE". Click Install. When done, you will be prompted for restart. Hit Yes! -
- Then go back to the folder with extracted files, and open "WPCREDIT.EXE"
- A ms-dos like window will pop-up. Move the blinking block (with arrow keys or your mouse pointer) until it says Offset 6F at the buttom. Now, click on the two digit number where it says "HEX", and change it to 1F (The Hex for Offset 6F would have previously been 9F, 8F or something else). Hit Set.
Your idle temps should now start falling.
You would have to do this hack/tweak everytime you rebooted your computer if it wasn't for WPCRSET.
- Go to directory and run "WPCRSET.EXE"
- Look at the top of the window: Enable select "Start" and make sure Device is on "enable"
- Then click Add. Enter 6F for the register, and 1F for the data
- Click Ok and you'll be prompted to restart.
Once, you rebooted, open WCREDIT again and see if the 6F register is still on 1F. If it is, then that's it..You're all done.
Here's a Screenie of how it should be:
This only brings your idle temps down, and not your full load temps
It should work for all nforce2s, and use at your own risk
Check your nf7-s for CPU Disconnect. Most other nforce2 motherboards do not have this feature in the bios...so this tweak might prove useful.
READ THE WHOLE THREAD BEFORE TRYING THIS!
If you run a Distributed Computing project...then obviously this would be of no use to you

It activates the C1 (and maybe the C2) function Athlon XP CPU's support. Most mainboard brands have this feature as an option in the bios you can enable and disable. I just found out that EPoX doesn't have that feature. So what you're doing is just using a direct reg tweak to activate it. It's not like you're forcing anything, the Athlon XP chips are made to support this feature so it shouldn't do any damage.
When the CPU is idle the mainboard will send a command to the CPU that will cause a part of the CPU to be deactivated (and therefore not produce any heat). That's why this tweak only works on the idle temp and doesn't change anything on the load temp. Ofcourse as soon as the CPU power is needed the deactivated part will become active again, so it should have any influence on the performance of the CPU.
Strangely, my full load temp has decreased 6º C degrees too.
