Asrock 2core1066-2.13G mobo with XFX Radeon HD 6770 850M GPU

[Legocar]

Hi

I'm in the process of upgrading my stepson's pc so that it's better equipped for gaming. However, having upgraded the CPU, RAM and PSU without too much difficulty, I've hit a problem with the graphics card. The previous card (an NVIDIA 8500GT) was working fine but the replacement isn't being recognised at all.

When its installed, the bios (which I've confirmed is the latest version) just reverts back to the onboard graphics and acts as though the new card isn't even there. I've tried playing with the graphics and PCI-E related BIOS settings and confirmed that the new card is getting power (enough to drive its cooling fan anyway).

The new 600W power supply should be powerful enough to crank the hardware (it has dedicated Graphics Card connectors) so I'm at a loss to understand why I'm not getting any signs of life from it.

My first question is, are there any known compatibility issues with this combo?

Secondly, can anyone think of any other reason for this apart from a faulty graphics card? (I'll be trying it in a donor machine shortly but I need to track one down with the right power supply plugs)

And finally, just in case I've been unlucky enough to receive TWO duff power supplies in a row, can anyone point me in the direction of some information that would tell me what sort of voltage I should be seeing from the relevant pins on a 6-Pin PCI-E connector?

OK so I've just tried the card in a donor machine and it worked fine!

So basically I have a card that works but not in this motherboard and a motherboard that works with other cards.... what gives?

Any help, advice, guidance, etc. gladly received. What are my next steps?

Are you using the latest BIOS?
If so and that didn't help you need to PM ASRock tech rep Emily and point her at this thread.

There's been lots of threads about Graphic card problems and mouse/keyboard problems, etc.
Emily can hopefully supply you with a working BIOS.

Oops, I almost forgot.

PSU colors:
Black - negative
Yellow to any black - 12v
Red to any black - 5v
Orange to any black - 3.3v
Purple to any black - 5v standby (on even when the computer is off).

PCIe cables are 12v (yellow - black).

Those are the common ones used on a modern board.

What is the brand/model of your power supply?
Can you borrow a psu to test with?

Re: Asrock 2core1066-2.13G mobo with XFX Radeon HD 6770 850M GPU

Thanks for the info guys. I've PM'd Emily, so hopefully she can help.

The PSU is brand new and the main reason I replaced it is because the card wasn't working with the previous PSU. It's an Alpine Silent Power 600W. It's not a particularly expensive one (a decision I'll probably end up regretting) but I've just put a voltmeter over it and I'm getting 12.4v across all pins of the GPU connector. The card worked in the donor machine which only has a cheap and cheerful 350W PSU and I had to use molex to 6-pin adaptors!

To be absolutely honest, I discovered after my last post that the BIOS wasn't actually up to date (v1.0 instead of v1.1) but I've now updated it, gone through the same process of trial and error with the settings and still no joy with the new card....

OOPS!

Apologies to Emily for bombarding her with messages.....

I hadn't enabled the "Keep a copy of Sent messages" option in my profile. So when I sent her a message then checked my Sent items to make sure it had been delivered, it was showing nothing.... so I kept trying DOH!

Can you borrow another power supply to test with?
This might help to confirm that your current psu is OK.
On rare occasions, some power supplies have compatibility issues with some motherboard models.

Using a digital multi-meter (DMM) isn't an adequate test, it can only show that one or more of the psu power rails is faulty.
Can you borrow a similar or higher end video card to test in your system?

Re: Asrock 2core1066-2.13G mobo with XFX Radeon HD 6770 850M GPU

I've already tried the graphics card with the original PSU that was in the PC. When it didn't work I ordered this new PSU. I've also confirmed that it DOES work with the PSU in the donor pc.

Everything is pointing to a compatibility issue between this mobo and the card. If I was certain I could find a similar performance card that definitely WOULD work, I'd replace this one. My problem is that on paper at least, there shouldn't be any issues between these two bits of kit.

It could be an issue with your new power supply, but your best bet is probably to buy a similar card in your price range.
Can you exchange your current video card for a different video card brand or model?

[QUOTE=proflim;414196)Can you exchange your current video card for a different video card brand or model?[/QUOTE]

Unfortunately it was bought (new) off an Ebay trader who went to great lengths to point out his stringent Returns Policy. Can't see him being particularly sympathetic if I return a perfectly good card just cos it may or may not be imcompatible with my PC.

And I'm still left with the conundrum that I don't know which cards WILL work and when my only way to find out is to "buy one and see", it becomes a potentially very expensive proposition.
I've already had to pay over the odds to find RAM and a CPU that suit the motherboard AND offer a worthwhile upgrade over the original parts. If I also lose money messing about trying to find a suitable CPU I'll end up worse off than if I'd just bought a new PC

Re: Asrock 2core1066-2.13G mobo with XFX Radeon HD 6770 850M GPU

The only way to be reasonably sure is by testing with different components. If you could test with the "donor" system's psu installed in your system, that might help. You could pay a shop to test your system, but that doesn't come cheap.

In a recent thread, the OP couldn't borrow any hardware to test with. His only option was to have a local shop test his hardware before he paid for out of warranty service to fix his apparently dead motherboard. I suggested that he include his power supply when he brought his system to the shop. In his case, his psu was at fault and the rest of his hardware was fine.

I don't know what your consumer rights are on your side of the pond. Try contacting the seller and tell him you want to swap your video card for a similar brand/model. You might include a link to this thread so that he can see everything that you've tried.

I've been around the block more times than most (i.e. younger) forum members and I've long since learned that you win some and you lose some. At this point it is one of three things; user error, faulty hardware, or hardware incompatibility. From your testing it looks like user error is not the cause unless your motherboard requires some out of the ordinary electrical connections. Re-read your mobo user manual as if you were a newbie who has never installed a video card before. Sometimes getting back to basics will fix things where a required step wasn't done.

Nothing ventured, nothing gained; it can't hurt to ask.

Thanks ProfJim

Regarding consumer rights over here, they pretty much go out the window where Ebay is concerned. There is a small amount of protection from being sold a duff product but even the best sellers would be unlikely to accept a return about 6 weeks after it was originally shipped unless there was something physically wrong with the item.

As for user error, I'm the first to admit that I'm no expert and regularly miss the obvious when searching for the exotic..... but on this occasion I honestly believe that I've gone over everything enough times to be pretty certain that its not (just) me that's wrong. The fact that another graphics card (albeit a less potent one) plugs in and works effortlessly (no bios changes, no special settings, no bother.... it just works) is enough to lead me to believe that this is a compatability issue.

I'm hoping that Emily can provide some insight..... if I haven't upset her too much with my earlier Spam attack
