PC wont POST with 5830.

[wyze]

I've been messing with this for days, tried 2 different cards, 3 different PSU's all with the same results. When I kick the power on, I hear 3 beeps, no video. My card I am replacing is a EVGA GeForce 8800GTX which works fine, but is obviously a shitty mining card.

This is an older system, so I've come to the conclusion that it is a problem with my motherboard. Please correct me if I am wrong.

Motherboard Model: MSI K9NBPM2-FID
Video Card Model: SAPPHIRE 100297-2L Radeon HD 5830 Xtreme
Current PSU: Antec HCG-520 520W

I've also tried the XFX Radeon HD 6950 in the same board with the same result as the 5830.

Any help is greatly appreciated.

Thanks,

Hmmm.. i'd say there is something up with the PCIE slot you are putting the cards into... If neither  'modern' card will work, it could be an issue with the signalling, and it being an older not so standard PCIE 1.0 slot? Remember, both of the cards you mention are PCIE 2.0, and so should be backwards compatible.. but perhaps it is a case where they are backwards compatible with a slightly newer slot then you are sporting on that board.

I'd recommend looking for the latest BIOS flash for your mobo, and flashing... (use the old card)

See if that allows it to boot with your new card.

I also suggest BIOS flashing. I had a problem once with a mobo that said it supported 45nm, but required a BIOS update to actually be able to use it. Most likely the same case.

It has the latest BIOS v5.8, which are from 2008. The board does have on-board video which I can use too and that works fine.

I did a lot of reading and researching before posting and couldn't find anybody anywhere talking about using this board with a PCI-E 2.0 card.

Nor could I, I was just digging around myself... You may be out of luck. If you plug the card in, does it automatically try to disable the onboard? or will it boot if onboard is left on, and the card is just in? Also... does the PS have all required power connects? Like your not running any two molex to 6pin adapters or anything right?

The PC will boot if the card is left in and I plug the monitor into the onboard DVI port. Yes, on the new PSU I am using it has 2x PCI-E connectors and that is what I am using. I think I may be out of luck as well. .. I found a board on Newegg that is AM2/DDR2 with one PCI-E 2.0 port on it for only $50. I think I will just have to order that board. Thanks for all the help.

Once it boots on onboard video, does the machine see the video card at all? If so, can you install drivers for it... If so.. then can you mine with it??? See where I am going with this?

i read that cards since 47xx have problems with "Mobo with old socket 939"
read it in faq for 5850

so i m sure that problem because of ur MOBO

Pci-e 1.0 card is compatible with Pci-e 2.0 slot. However, pci-e 2.0 card NOT backwards compatible with pci-e 1.0 slot. As strange as it is, there some mobos with exceptions, depending on the chipset. But one thing is for sure. That mobo has an OLD nvidia chipset that is definitely NOT compatible with a pci-e 2.0 card.

That actually makes sense.

Anyways, I went up to my buddy's PC shop and got the Foxconn A74ML-K for $50 and everything is working great now. Getting 310Mh/s so, no complaints here!
