Another Chaintech 7NJS (nforce2) Boot Problem
RKM
a Corsair 512 MB DDR 400 memory module. After putting it all together
(no small feat given the lack of good documentation), I cannot get it
to post. Basically, the computer turns on (fans power up) and then it
shuts down (blinking light on the power led). I have read other posts
on this subject and tried everything indicated i.e. removed all
connections except main power/power switch, reset jumper JP1 (CMOS
clear), removed all screws to see if it was a contact short problem,
but still nothing works. The computer still won't post.
Any other suggestions? I plan on picking up another socket a
motherboard to see if the CPU/memory are bad, but I suspect the
motherboard is the culprit based on what I have tried and feedback
from other posts on this board.
Any help would be appreciated. Thanks

with cases aren't adequate for the newer AMD-based motherboards. AMD
motherboards supply power to the CPU via the +12 supply. Many are only
rated at 10 amps on that buss, and aren't adequate.

Plus 1080AMG. It comes with an Antec Truepower 430 watt power supply
that according to the manual is an ATX12V form factor power supply.
Here's a link to the case and power supply.

It seems like it should be fine with this motherboard.
Thanks for the input.

post by ragecage. The memory I have is the same that he mentions
below. Corsair XMS 3200 DDR 400 memory (512 MB stick) CAS 2 rated.
I will run over to BestBuy, pick up some CAS 2.5 memory, and see if
that will let me boot the motherboard.
Jeez, if it works, there goes my logic in paying for better memory.
"Thank you. Just a follow up - I get the Asus and wouldn't you know
it, the damn thing wont post out of the box! No beeps, signal,
nothing. Needless to say I am questioning not only my sanity but
second guessing my ability to install a simple mobo (it ain't rocket
science). Some hunting in the groups turns up an incompatibility w/
Corsair XMS 3200 memory. I bought 2 256 sticks for this board and
sure enough -that was the problem. The board incorrectly identifies
the sticks as CAS3 (they are CAS2). Since CAS3 is out of spec, the
board will not post. Solution? Stick in an older CAS2.5 stick,
change to CAS2 rating, powerdown and swap out the other ram -works
like a charm! Corsair is aware of this issue but says it's not really
their problem -more of a standards thing. Anyway, I bring this up
because this same issue might be affecting the Chaintech as well.
Many of the "anomolies" I experienced when trying to get that one
going were similar to the ASUS. I already RMA'd the board so I can't
verify it but it is certainly something to keep aware of if you have
Corsair memory and are having problems with the 7NJS. Cheers!"

still no go. I guess I am stuck right now with RMA back to googlegear
for another board.
Too bad.

There are no industry standards for anything above PC2700 at the moment
(JEDEC standards.) Therefore using > PC2700 at the moment is a bit of pot
luck and it depends on the motherboard. Each manufacturer builds >PC2700 in
the way it seems best to him to do it--not according to an industry standard
design for ram and PCB that virtually guarantees it'll run regardless of
motherboard.
In your case, however, I'd check two things first just to make sure:
(1) Make sure the connector for your floppy drive is not connected backwards
(it's not idiot-proof and so you can do this--I did it myself.) Symptoms
are similar to yours.
(2) If that doesn't work make sure your cpu fan is connected to the correct
power header on the motherboard--I don't think system will post unless it
is. The header will be marked "cpu" and the connection is idiot proof.
(3) If still no luck remove your cpu heatsink/fan and inspect the cpu
visually to make sure it is installed properly, and then reattach your
heatsink carefully, making sure that the heatsink aligns with the contours
of the cpu-socket A block--it is (heatsink) specifically designed to align
to the contours--but you'd be surprised at how many manage to put them on
backwards...;)
(4) If you are getting power and fans are spinning it probably is not your
power supply. BTW, I *was* using an Antec TruePower 430 with mine--and I
swapped it with a Power PC&Cooling PSU I had, temporarily. When I put the
Antec back in, however, it was *dead as a doornail.* I don't know what
happened as I've never had a PSU go out on me before. If your PSU is dead,
however, no fans will spin and nothing will happen.
Just some quick tips from the top of my head--hope you get up and
running...!

The board I was talking about was the new Asus 7N8X not the Chaintech.
I was just giving a heads up to see if that might have been the
problem as well (since I never thought of it when I had the
Chaintech). Looks like it isn't as other people are saying that the
Corsair 3200 boots at CAS 2.5. The Asus recognized it as 3.0 after
first post and would not reboot or post until I reset the CMOS "clear"
jumper. Since the only way I was able to boot the Chaintech was by
clearing the CMOS each time, I thought there might be a RAM
compatibility issue on this board as well -guess not. Go ahead and
return it, it looks like there are a few of these DOA out of the box.
(I couldn't even update the BIOS on the 7NJS as the system would just
hang while it decompressed AWDFLASH.EXE.)
I guess I'm still trolling around in this group because I guess I am
looking for closure on that board. Was it me giving up too early or
was the board really defective? From everything I am reading, it
wasn't me... :)
Good Luck! (BTW, the Asus is running fantastic)

I'm glad you like the Asus--I was going to try it if the 7NJS didn't work
out--but so far it's been a very nice board--no problems to date. I think
it's kind of funny what you can read about products--I'd say the chance is
about equal to pick up a bad board no matter what you buy--out on the
nForcersHQ.com site in the forums many more people are reporting problems
with the Asus boards--*chuckle*--which scared me about as much as the
Chaintech comments scared you...;) Often first production runs of a product
can be a bit iffy regardless of manufacturer. Right now, though, this
Chaintech is a good deal more stable overclocked than my former MSI KT3
Ultra ARU used to be, using the same ram and cpu--and up until the 7NJS I
had considered that MSI board the most stable motherboard I've owned in 15
years...!...;) I just think that some unlucky folks (like you) are picking
up some of the first-run slip-through-the-crack boards which seem to be out
there regardless of manufacturer. I *wish* your 7NJS had worked as well as
mine because I'd like to ask you how they compare with the Asus--but then if
yours had worked as well as mine you'd still be using it *chuckle*--Oh,
well...One thing that I've heard about the Asus nf2 boards that I'm not sure
I like is that they use a socket thermastore for cpu temps instead of the
AXP's internal diode. Is that right, or have you looked into it? It's a
small thing--but basically I think these nf2 boards are the best thing going
right now for Athlon--provided we're lucky enough to get good ones on the
first go, eh?...;)

least this time I get an error code from the digidoc display. The
error code is C1 which indicates a memory compatibility/memory
bad/memory seating problem. I have reseated the memory several times
but still get the problem.
In addition, I get the error code with the corsair 512 M B PC3500
memory and with a stick of 128 MB PC 2100 memory.
Is the motherboard so sensitive that it only works with PC 2700
memory? This is getting ridiculous.
I am heading back to best buy to pick up a stick of PC2700 to see if
that works.
Any other suggestions would be appreciated.
Thanks

why that worked but it did. Yeah! It now works with the 512 MB
corsair memory and I am currently loading Windows 2000 on the PC.
The only hangup has been the onboard LAN. I can't seem to get it
recognized within Windows 2000.
Anybody else having this problem?
