Problems with a 9800GX2

[Buckeye]

Hi everyone.

Trying to get my bench setup with BlackOps. I have flashed to G28 using a E8500 and RAM shown in my sig.

The board works great with a 8800gtx but as soon as I put on a 9800GX2 it will not post, it will not even get to BIOS.

This happen from the very start of setting this up, meaning it was the first GPU I tried to run on this. I could not get it to work so I put in a 8800gtx and everything worked fine.

I have searched around and just not coming up with anything that would explain my problem.

Thanks for any help !

Do you get a post code on your board?

[Slovnaft]

have you tried the card in other mobos? my first guess would be an issue with the card.

[Buckeye]

I believe the code was E7, I will recheck that tho.

Yes the card came from the system in my sig and has had no problems what so ever.

I tried the card in the blue and red PCI slots but recieved the same problem.

ooo hows the quad-sli nowadays? I'm about to go totally nVidia (sig rig is intheworks) and there hasn't been a whisper about quadsli lately.
Sry, a bit OT.

Seeing as there have been recent posts of 9800gx2 with blackops I have no reason to believe it's the board alone.
did you do your driver cleaner, etc?

With the BlackOps you can only use 1x 9800GX2 so no Quad SLI. And with that it has been a complete clean install so no need for driver cleaner.

As soon as I plug in the 9800GX2 it will not post, boot or anything.

Quad SLI runs just fine on the equipment in my sig.

Maybe 1E? If yes, you probably have the same situation like me since r600 on ati-side and g92 on nvidia-side.

A long time ago I had a 8800 gts 320 which worked perfect for me. After I put in a 2900xt (or later a 8800 gts 512) my monitor (HP LP2065) didn´t show a picture. But after several attempts I realized that the system was up and running because I could shut down the rig by pressing windows -> arrow up -> enter -> arrow down -> enter.

Here is the thing that I found out: My monitor has a problem with newer vgas because everytime I boot up the system first time a day, I get a black screen (but as said the system is running fine).

Since I use a kvm-switch I change the pc and start a pc that has a simple onboard-vga. When I get a picture on my monitor I can switch back to the other pc, power it on and then I get a picture on that too.

I don´t know the reason why this happens but I can handle that. If it is the same issue with your gx2 than you can try this: Put in your 8800 gtx and power on your rig. When you have a picture on your screen power down your pc (but don´t switch off your psu). Change cards to gx2 and power on again. If it´s the same problem you will get a screen than....

I've an EVGA e-GeForce 9800GX2 SSC in mine, and it has worked fine from day one even prior to drivers being loaded. No help other than saying it works for me.

have you tried both dvi slots on the card?
did you check if the cards power cables are connected properly?
is the card seated in the pciE slot properly?
whats the boot code, did you check again?

there is a pciE issue with p35/x38/x48 which causes the vga to not initialize properly.
Ive seen this on many boards, especially when i worked at cellshock where i rebooted a dozen systems every couple of minutes each and swapped the memory.
Anyways, moving the vga around from one slot to the other usually solves it after changing it a few times.
sounds like you tried that already tho, so that doesnt seem to be the issue... weird...

what psu are you using?

The PSU I am using on my bench is a Cooler Master UCP 1100W, this is a Beta Test unit that I have used for awhile now. With my rig posted in sig it has held a max load of 861watts with that system and 2x 9800GX2's. I don't think it is the power supply.

I will have to reinstall the 9800GX2 back into the BlackOps again and double check the codes as I do not remember what they were.

[saaya]

if you can do that thatd be great... and can you keep it set up for a few days and try a thing or two our engineers might ask you to check what the problem is?

[TheGanG]

I have my EVGA 9800GX2 SC on BlackOps and works pretty good (on slot 1 or 2)... But a few days ago tested a 4870 and a 3870X2, then my GX2 SC didn't work again, not even a sign of live... Tried a few times to install my VGA again and worked... Installed GX2 SC VGA drivers again...

[saaya]

hmmmm so you had to insert the card a few times?
take it in and out, in and out, and then it worked?

thats exactly the pciE issue i had on so many boards...
actually ive even seen it on amd boards... its some weird pciE thing... hmmmm
maybe its bad contact in the pciE slot?

[SF3D]

Buckeye-

What post code you are getting with 9800GX2? You said it doesn't even get in to bios, so you don't have display signal then.

Have you tried both 1/2 DVI connectors in 9800GX2.

It will not get into BIOS, or post. Yes I have tried both slots and both connectors. All lights light up fine on the card, the green and blue lights, fan comes on. I tired many times reinserting the card to make sure it was installed correctly.

I will install the card back in today and get the codes.

Yeah, PC was working, i kno that, but my LCD was black and sum GX2 lights was out... It may be a pci e issue but i use different VGA cards and it didn't happen again... Jerking* my GX2 right now, it still works without an issue Thanks...

The Nvidia 9800x2 Video configuration mode working only in this mode:

The dvi cable working only when at boot sistem the VGA cable is linked to first port under blue led.


The Vga power plug at sistem boot must be in green led condition .


My Zotac Vga test 9800GX2 working correctly with any official bios P02->05 and any beta bios G25->G30

[Buckeye]

Well interesting. On my Nvidia machine I have the video cable on the other connector and it works fine.

On BlackOps its a no post with error code of 7F

So I just relooked at my Nvidia machine which is in a TJ07 and the video cable is connected to the very top VGA connector, or the closest VGA to the main PCB of the card.

On BlackOps I used the same VGA connector and get error 7F

I just tried the other VGA connector and it now boots. Funny thing is I am 100% sure I tried that on the weekend and had a no boot.

I will keep messing with it to see if I can reporduce the same errors codes or VGA connectors.

[Slovnaft]

See this is why i just traded this board for a QX6850. random seemingly inexplicable problem.
oh and ZillaPct seems you need to update your sig...

Hi Buckeye, the error code 7F has this troubleshooting info:

7F
When the system detects that a critical error happened during the last boot attempt or several boot attempts failed, so OC recovery kicked in. There should be a message displayed on the Display informing you that OC revocery kicked in and that its waiting for your input to enter BIOS. If you cant see this message cause your Display stays black, please check the description for POST Code 2b.

And here is 2b:

2b
When the system powers on and the Debug LED shows the usual POST code sequence but hangs on 2b or you get a beep code as soon as the sequence reaches 2b, then the Mainboard cant detect your Videocard properly. Note that the POST code sequence might not halt at 2b but continue, so the final POST Code it displays could be FF, 1E or 7F which means the Maiboard booted, entered BIOS, or OC recovery kicked in and is waiting for Input to enter BIOS. Since the Videocard couldnt be detected properly you will only see a black Monitor and either 2b, FF, 1E or 7F. Check if there is something wrong with the Videocard, the PCIE slot or BUS, the Monitor or monitor cable. Turn the Monitor on and off, switch the Monitor cable from one D-SUB or DVI plug to the other in case your Videocard has two. If this doesnt help then reboot and load the optimized defaults. If that doesnt help either try another Videocard if possible, or try the Videocard in another system to make sure its working properly. Try another monitor or try the Monitor on another System.

i too am having a problem with my 9800gx2 - only a week old

only got it to work twice and just about managed to get screenshots of 3dmark 06 results and GPU-Z.0.2.7

my board would power on with a post code of FF then power off

on next power on it would continue until post code 40 and sit there for ages -with no display on the monitor

then it would continue on to post code 54 and stays beeping continusly and would go no further

if i disconnected the 6 pin and 8pin power cables my board would get to boot

i have an RMA got from BFG but i am holding off just to see if anyone has any ideas

i am using a bfg 8800gt oc with out any problems with the same settings

any help would be appreciated

my sig is current with my setup at the moment

Thanks Xello !

7F means the board booted fine and is showing you the "OC RECOVERY" message. if you hit any key itll enter BIOS and should jump to 1E.
So basically the board booted fine, the vga just doesnt put out a signal to the display, or the display isnt working for some reason.

you will get these symptoms when:
the wrong vga plug is used
the vga cable is not connected properly
the vga cable is broken
the vga power cable is not connected properly
the psu is too weak for the vga
the monitor is damaged
there is a bug with the vga BIOS
there is a bug with the mainboards BIOS

In case of the 4870x2 cards for example it was the vga BIOS, thought its always hard to point fingers and actually pretty useless, lets just say it was a compatibility issue between vga and mainboard.

See this is why i just traded this board for a QX6850. random seemingly inexplicable problem.

sorry to hear that... what problems exactly did you get?

oh and ZillaPct seems you need to update your sig...

im not sure... hes talking about PL8... not PL12 or whatever the asus 710fsb was with

i too am having a problem with my 9800gx2 - only a week old

only got it to work twice and just about managed to get screenshots of 3dmark 06 results and GPU-Z.0.2.7

what happened after that? so you were benching 3d, all was good, and then the card didnt boot anymore?

my board would power on with a post code of FF then power off

on next power on it would continue until post code 40 and sit there for ages -with no display on the monitor

then it would continue on to post code 54 and stays beeping continusly and would go no further

check the post code guide i wrote here:
http://www.xtremesystems.org/forums/...d.php?t=190952

what you are describing sounds like a memory issue.
Sounds like you pushed the memory/fsb too high and its not stable.
whats memory and cpu are you using and what speeds and voltages are you running it all at? the same configuration works with another vga though?
thats quite weird...

if i disconnected the 6 pin and 8pin power cables my board would get to boot

thats normal afaik, you get the red leds on the power plugs and then it doesnt boot right?

[Xello]

Yeah error code 54 with beeping, i always got that when i tighten CAS too much, so might try looking there.
