It just takes over one minute to detect the two devices during the post screen. Is this normal?

Thanks for the help pantner.

well there you go...you have the hard drive on "Master w/ Slave", but there is no slave...put it on "Master/Alone", which i think is taking the jumper off completly...

I just realized I did that. Instead of using the necessary screws to screw into the standoffs, I stupidly used more motherboard standoffs to screw into the standoffs.

Since I used "standoff to standoff" instead of "screw to standoff", could it be that its not grounding all the way like it should? Could this be causing my problem?

I already tried swapping the video card, so thats ruled out. I swapped the ram, so I can rule that out. Cleared the CMOS, nothing still.

I got the video card seated better. I'm thinking its the standoffs.

Any opinions?

I had similar problem when I built my new system about 3 weeks ago. I tried booting up my new 9NDA3J with the same OS installed for my previous NForce2 system. I was getting a black screen. I just did a clean install of windows XP and the problem was gone. I learned not to try to boot a hard drive that contains drivers from a different motherboard. I do not remmember if my port 80 value was FF.

Good luck.

Yes, BUT, he is getting NO VIDEO AT ALL, it will not post, nothing, nada, zip, zilch, zero...
its not a case of it not booting into windows...its a case of him getting absolutly no display on his monitor at all..

well, thats how i understand the problem...

Yeah that is exactly the problem Partner. Sorry for not answering back sooner, the only time I get any free time anymore is on Wednesday nights and weekends.

I just fixed the screws and standoffs issue I messed up, unfortunately nothing.

Here is a listing of my system specs:

Epox 9NDA3
A64 3200
1 gig of Corsair PC4400C25
Sapphire X800XT
Seagate 300gb IDE hard drive
Plextor PX-716A
OCZ Powerstream 520watt PSU
Cooler Master Stacker
XP-90 heatsink and 92mm Ultra high speed Panaflo fan, thermal compound AS5

When I hit the power switch it seems like everything fires up, except that I have no video to my monitor. Port 80 is still just saying FF. My monitor just sits in standby, can't get to bios or anything.

I'm going to disassemble the computer this weekend and put it back together again.

Any advice you guys could give would be greatly appreciated.

p.s. Also, this is my first time using an aftermarket heatsink and thermal compound. My question on this is; If I remove the heatsink will I have to clean it and the processor and redo the thermal compound?

 

[Goldenboy]

Hi Andy Bogard, it is good to clean the thermal compound off the cpu and heatsink when you take it off and reapply. You can use 90%+ isopropyl alcohol to clean it.

Replying to pantner:
I finally took off the jumper to make the hd single setting, and now post detect the drives at normal speed. I guess having the jumper set to master w/ slave setting really slows down the detection during posting, weird.

Now I have a new question. I have the antec P160 case, it doesn't come with a CSPK cable to connect to the 9nda3J CSPK header connector. Normally posting makes one beep sound, but does it really matter if posting makes no sound? Sorry it is kinda off topic here. But advise greatly appreciated.

 

[Goldenboy]

Hi Andy Bogard, I was just surfing online and found that the Sapphire X800XT requires a power extension cable to connect to the vid card. Just curious if the agp version needs the extension cable or not. Maybe that was for the PCI-e version. Sorry if I can't be much more help.

 

[pantner]

@AndyBogard,

unplug everything that is not nessesary for the computer to post...this includes all hard drives and CD drives, case fans, neons/cold cathodes and re-seat all connections (ie the ATX 20pin and 4pin connectors, and any other connectors, ie GFX Card Power/AGP Port)

then clear the CMOS, and also try booting with only 1 stick of RAM...

@Goldenboy,

told ya so

the reason it takes a long time to post when it is on the "Master W/ Slave" setting, is because THERE WAS NO SLAVE, and it was looking for it/trying to detect it...

thats one of the things i hate about WDs...everyone else (Seagate, Maxtor, Hitachi, Samsung) just has Master or Slave....

 

[tpicciani]

I've been running a rev 1.x motherboard since late November. I've had a few issues but the board is stable.

I'm not overclocking but I'm using PDP ram in slots 3 and 4. 1 gig (2x512 meg) Dual Channel DDR.

The problems I've had:

Pc would shut down unexpectedly. --> tracked to a bad Thermaltake 560 ps. Replaced with an Enermax 475 Noisetaker.

PC would hang at the first screen and while in the bios.

Found that there might be a bug in the health check routine. Turned off display health info on boot option. No more boot issues.

Upgraded yesterday to an MSI Nvidia 6800GT card. System is stable but +12v is now reading 10.69. I don't know how the thing boots but it is fine.

Only problem now: the bios hangs when I go to the health check screen. Updated bios but same problem.

Tom P.

 

[alexandreBR]

as far as I know the EPoX 9NDA3+ doesn't inform on +12v rail.... if you use any program which is trying to read it, certainly it will give crazy voltages... well, at least here I have no information on +12v rail.

Oh guys, I've had a bit of courage and I've overclocked my system... now it's 245x9.... I've run 3DMark01, 3DMark03, SuperPI and OCCT with no erros... also, I've run Prime 95 during 6 hours and no error message was shown... really pretty stable... and with default vcore.. I've set it in BIOS as +0.075 because, as I've told you before, the Default Vcore is a bit low, always between 1.328-1.360... now it's between 1.392 and 1.460 (this voltage in full sometimes)..

well, towards the memos that I've asked you to give me a piece of advice, now I'm really confused... I can't decide between DDR PC4000 OCZ 1GB GOLD REV2 DUAL (2.5-3-3-8) and KINGSTON HYPER X UL DDR400 (2-2-2-5-1)... well, there's also the DDR PC4000 GEIL 1GB ULTRA DUAL (2.5-7-4-4).. the Geil one is really much cheaper than the others

and now, which do you think I should buy?

Geil is a good choice?

 

[Goldenboy]

Replying to pantner:

Yeah, it is my first WD hd so it is kinda weird as to how their hd jumper setting works. Like you said maxtor just have master, slave, CS. Gotta keep that in mind next time working with WD hd Again thx for the help.

Replying to alexandreBR:

As to the ram selection you have listed, I believe they are all good brands. It lies more on the cost and latency timing. For OCing, OCZ provides good performance but cost is higher. Geil and Kingston just as good but can be had at lesser cost than OCZ. You might also want to see which IC these rams are using too. I believe one of the forum guys did a sticky ram guide just search for it. I believe it was in the CPU/overclocking section, but don't hold my word to it. Just merely my $.02.

Tried reseating the connectors and nothing.

I know its probaly a stupid question, but: Do I have to put the CD that came with my motherboard into my dvd burner and do something through that?

I still get FF for a post code on PORT 80, and from I can tell that looks like a motherboard problem.

I'm about to order a NEO2 and see if I have better luck.

The Drivers etc are on the motherboard CD...it won't help with your problem...

Do you know anyone else with a Socket 939 Processor???

do you have a spare PSU to try on the motherboard???

 

[AndyBogard]

@Partner

I knew it was a long shot about the cd thing, I'm just annoyed that this computer won't work. I figured I would give my stupidity a chance to see if it could help.

Unfortunately no I know has a 939 processor setup.

I have 2 generic PSUs, one is a 500 watt PSU powering my current system, its CompUSA brand. The other is a 350watt PSU (Manhattan brand), I was going to build another non gaming machine using this one.

Do you think its the PSU? I'm not saying its not possible, but everything else connected fires up, and the rail indicator lights are in the green.

 

[UKnowWhat]

AndyBogard,

Here is my post over the OCW Forum and few posts down, how I solved my WD drives problem. I don't know whether it applies to you but I think my problem is very similar to yours.

----- My post ----
I just finished putting in my A64 3000+ with a 9NDA3+ MB. Everything went OK except for 1 thing, WinXP SP2 installation causes system repetitively crash with BSOD error 07E during installation. Update to the new Epox Bios ver date 2/15/05 won't solve the problem. After pulling a few hairs here & there, reading about certain type of RAM doesn't work, and especially after reading so many posts about the glory PSU with extravaganza juices on 12V supply, and read much of bugstop error 7E, I decided to put in a vanilla ATI PCI Rage video card as my primary video source instead of using my Matrox G400 AGP card (yes, I did all of the disabled fast write before doing this). Guess what? XP installed perfectly. Later I went to Matrox to download a new driver for my G400, everything went smooth since.

The moral of this story is don't replace your RAM or your PSU right away. There might be something else in your system that WinXP doesn't like. No one's problem is alike and Epox manual specified their MB only requires 200W and 300W PSU should be good enough for common people without a lot of toys in their system. I will tell whether my "400W" PSU will be good enough when I start tinkering with my A64.

A64 3000 not OC yet
512MB "cheap" value Kingston DDR-RAM PC3200
PSU A1 Power "400W" with only "15A" @ 12V
Matrox G400 AGP
WD 160GB
NEC DVD ND-2500
---- end of my post ---

I suggest you to

1) Set your BIOS to fail safe mode.
2) Put a vanilla PCI video card in and set your BIOS to power up with PCI video card as primary device.

Regarding the WD drive problem. I noticed that during power up, the MB hanged on detecting IDE so I just set the jumper position to single (no jumper). That solved the hanging of IDE drives detection, but then I ran into another problem after I have installed WinXP. See the post following that about how I solved my 2nd drive installed after I have successfully installed my WinXP. Right now my system runs stable at standard speed. No OC yet but I will do it later just for the heck of it.

I appreciate the fact your trying to help me UKnowWhat, but I have a different problem.

I can't even get to my bios. I can power on the computer and it seems like everything fires up, except that I get no video going to my monitor. I can't get to bios, or post. I haven't installed Windows yet because I have no video output. I already swapped out the video card and tried a 9700 pro that I have and still nothing, and I know the 9700 pro works because its powering the computer I'm typing this on.

I don't have a PCI video card around, if I did I would have tried that. The 2 PSUs I listed are PSUs not meant for the computer I'm having this problem with. In that computer I have an OCZ Powerstream 520watt PSU.

Heres my system specs (this is the one I'm having this problem with, newly built, everything is new):

Epox 9NDA3+
Athlon 64 3200+
1 gig of Corsair XMS PC4400C25 (DDR550)
Sapphire X800XT AGP
Seagate 300gb IDE hard drive
Plextor PX-716A
Cooler Master Stacker
OCZ Powerstream 520watt PSU

I've tried a different video card and no luck. I tried different ram and no luck. I've cleared the CMOS, no luck. I reinserted the processor, memory, and reseated my ATX and 12V connectors and still no luck.

Everything turns on in my system, even the fan on my X800XT (and my 9700pro fan runs too when that was installed) works. Since both cards won't output video on this setup I don't think its the PSU since both cards require different power connectors, anyways the fans on both cards work in this setup too.

My port 80 displays code FF, which from the manual looks like a motherboard problem.

I think its the motherboard. I'm probaly going to order a MSI Neo2 Platinum and hope I have better luck.

 

[UKnowWhat]

AndyBogard,

I know your video card works with other system, but I don't know whether your video card working with the one you are building right now in certain steps of power up. That's my point. First rule of troubleshooting anything is unless you have 2 identical systems, previous assumption does not hold.

When you said you have tried a different video card, what exactly have you replaced? Based on what you said about you don't have a PCI card around, I can deduce that it is also an AGP card, is that right? My speculation is for whatever the reason, the video primary is pointing to a PCI resource and that's you don't have one in it. To elimilate this possibility, you just have to have a pure vanilla PCI video card in to verify the theory. If you still have the same problem then the issue is some place else but divide and conquer of problems is the way to go.

FYI, my LED also displayed code FF when I have trouble with my board during my AGP video card BSOD error 7E.

 

[flipcody]

I have installed a A64 3200+ (939 winchester) in a EpOX 9NDA3+ motherboard. It is a great board and CPU but seems very finicky when it comes to memory. I know that the Athlon 64s are more touchy on memory. I can not run 2 dimms, the system only sees one stick. The machine will not boot if I try to run in dual mode (slots 1 and 2 or 3 and 4). It will boot when in single mode (1 and 3) but it does not read all the memory and memory runs slower. My power supply which is an Antec True 430 12v rail is 20A.

I have 2x512mb sticks of Corsair XMS 3200C2 (CMX512-3200) memory. When trying in 1 and 2 or 3 and 4, I get long beeps and a C1 message and can not even get into bios. When running in dimm slot 1 and 3 it boots fine but memory is only running at 167, and it only sees a total of 512mb of ram. These were not a matched pair, they were bought months apart. One is v2.2 and the other is v3.1. It looks as though arswihart on a post on page 2 used this same memory in dual channel mode. Arswihart, was this a matched pair when you bought them?

When in slots 1 and 3 I only see 512mb in boot screen. It only shows 512mb in windows and memory tab in CPU-Z. However, In CPU-Z I see both dimms in the SPD tab. If I have one stick in, it runs at 200 and if 2 in at 167 (even though the bios and windows does not see second dimm). I'm running the latest bios for the motherboard. These sticks ran dual channel on an ASUS A7N8X V2 Deluxe mobo.

I have tried the following:
1. I have tried changing memory settings with no luck. This includes memory timings and uncerclocking memory to 166, 133, and 100.
2. I have tried all the dimm slot combinations. I have confirmed that dimm slots 1 and 3 work and that all sticks work.
3. Tried 3 more different sticks (256mb PNY 2700 one sided, 512mb Corsair 3200 Value select, and 256mb Giel 2100). They all work on motherboard but no combination of 2 dimms works. It appears that when I have a stick in dimm slot 1 and dimm slot 3 (the only way to run non-dual channel with 2 dimms) the system is only running the memory in dimm slot 3: when I have the 512mb Corsair stick in dimm slot 1 and the 256mb stick in dimm slot 3 the system only read 256mb of ram.
4. Tested memory, I ran memtest86+ with no issues.
5. Tried all different settings on HT (1X - 5X).
6. Uping memory voltage to 2.6v.
7. Tried every bios version available for motherboard.

Any ideas out there? Do you think this a motherboard problem, faulty memory controller in CPU, or is the board/CPU that picky when running 2 dimms?

Anyone out there running this board with mismatched memory?

I have had a support ticket in EpOX's US websight and they have not responded to it in 3 days.

Thank you!

Both video cards I have are AGP.

I don't understand and see how my motherboard could be pointing to a PCI slot for video from default.

 

[tpicciani]

There's a setting in the bios that asks which bus to poll first, AGP or PCI. For some strange reason the default is PCI. You would think that Award or NVidia would set this to default to AGP.

A lot of people had problems in the past when the Soundblaster live cards were introduced because their pc's would think the sound card was a video card. So they got no video.

Check that setting and make sure you're looking for AGP as the first video device.

Or if your monitor's power light is just blinking (most monitors are designed to blink if it doesn't see a valid signal on its RGB)

 

[UKnowWhat]

Flipcody,

According to this Intel Dual DDR channel white paper DDR minimum requirement on matched pair (page 8)

1) Both modules are the same capacity <- you meet the spec
2) Both modules are the same speed <- you meet the spec on your 2 PC3200
3) Both have the same number of chips and module sides <- I don't know whether you meet the spec or not

That is if your modules also meet the spec on #3, your computer should reports 1GB at minimum when you installed those 2 on slot 1 & 3 (Single channel 64 bit wide - Epox manual page 3-5). If you do and the fact your system didn't report the correct memory size then here is some possiblities

1) Your CPU is defect <- memory controller
2) Your MB is defect
3) Epox has problem in their BIOS and also in their memory controller driver
4) Epox design didn't meet the DDR spec

You can eliminate #1 if you have another 939 MB to try out. So with the exception of your CPU (very low probability) and your modules having different technology, all fingers are pointing to Epox problem. And I just hope that #4 is not the main cupid, because then I will be on the same boat with you

 

[pantner]

@flipcody

try putting the VDimm voltages a little high, since you have corsair RAM it should run fine at 2.8v...BTW is that 2-2-2-5 RAM??? (sorry, i don't know Corsair item codes off by heart )

@AndyBogar,

no real help...im just curious, wat is the "Plextor PX-716A" you listed in your system specs???

 

[arswihart]

flipcody - Yes, I also have Corsair XMS3200 2x512mb from around 2002. I ran them in dual-channel on my previous 8rda+ and now on my 9nda3+. I could only run stable at 183mhz on the 8rda+ (limited by chipset more than RAM i think), now stable on the 9nda3+ at 200mhz @ 1t 2-3-3-10. They are in RAM slots 3/4 @ default voltage.

I have a 3200+ (core = +0.1v), and my other BIOS settings are 240htt (10x = 2.4ghz), mem 166 (ddr400), httx4 (960mhz). I have all other performance settings, like "turbo" "enhanced" all turned on in the BIOS.

Here's the rest of my specs:
Athlon 64 3200+ (zalman alcu-7000 at 1800rpm)
9nda3+ rev2.1 (2/2/05 bios)
Corsair XMS3200 2x512mb
Abit ti4400 (nv1 cooler)
Chaintech av-710 soundcard
LynxOne sound card
2xwd800jb
nec3500a dvd-rw
pioneer108d dvd-rw
Antec Neopower 480 PSU
Lian-Li PC60-USB (3xL1a panaflos)

I have my NB hsf unplugged and it never even gets warm to the touch (some peripheral air movement from arctic cooling nv1 video card cooler + intake air flow). My CPU and system temps are typically 39/39. CPU never goes over 41 i think, these temps seem pretty low compared to others, and I'm happy about this in particular.

The only problem I've had with this mobo is that the lower back panel USB ports drop their connections, either after rebooting/shutdown-restart/and sometimes randomly while in Windows, making them basically unusable. The USB headers on the board seem to work fine though, so I decided not to RMA.

Thank you for the reply arswihart! Did you buy your memory as a matched set? Would you happen to know details of the chips of your memory?

My Corsair XMS 3200C2 memory (2 dimms) detail is as follows:
v 2.2
no brand but chip has what looks like globe with W on it.
W942508CH-6
03165I

v3.1
infineon

Thanks!

FYI, if your RAM's module utilized one kind of RAM chips organized as 32Mx8 bits and other module utilizes different RAM chip organized as 32Mx16 bits, then it will never work together as dual channel. On the other hand, the most common problem is the MB designed with low density type memory architecture and if you try to use the high density memory it will report incorrect size of memory or not even boot up into OS.

PS: I just order another 512MB Kingston no-name PC3200 from another retailer with same manufacturing number as my original RAM in my A64 system now. If it works in dual channel, that means Epox MB meets the DDR dual channel spec. If it doesn't work, my children will each have 1GB in their computers to play their games or watching movies more "efficiently".
