I'm having booting problems with the Asus Radeon 5850. This is the second one I try (RMA'd the original..) I have an M2N-sli with a 750wtt power supply with 2 dedicated 6pin power connectors.

Put the new card in and the system refuses to boot-up. A few hits of the re-set button seem to get the pc up and running. BUT the system will not re-boot in subsequent times.

I've re-seated the card. I've checked the power connectors. No beeps just the fan spin up with a DVD seek of some sort which just loops till I hit the reset a few times.

I even removed power off an extra Hard drive plus the floppy drive in order to remove any extra power drain. No success.

The system is stable using my older vidcard....an Nvidia 9800gtx+ also with a dual six pin power connector.

Strange. Is the mobo incompatible?

My whole sys is this:

M2N-SLI
Athlon 64 x2 6000+
ATI Radeon HD 5850 (unstable boot ) or Nvidia 9800gtx+ ( stable boot )
Creative X-fi pro
DVD-RW
floppy drive
230gb hd, 300gb hd, 80gb hd.
750wtt PSU Thermaltake
2x120mm fans
Windows XP SP3/ Win7 dual boot

Once the PC boots thru the system seems to work fine, ran some benchmarks wiht no issues. Well I'm about to reboot and change the vidcard.

:(


PS After the vidcard swap the computer boots up fine.... I'm very disappointed.

I can't believe the mobo cant provide sufficient power.

It's unlike that it's the mobo... try unplugging the system and holding the power button for about 30 seconds, and then plugging it back in and see if it works ok.

That motherboard is finicky with pci-e 2.0 cards. I'd make sure to update the motherboards bios with the old card in. Check for a bulging capacitor that is just below the 4 memory slots, its tiny so its hard to tell.

Also do you have an exact link to that power supply?

Here's a link to the PSU manufacturer...

http://www.thermaltakeusa.com/Product.aspx?C=1264&ID=1502

I've tried the pulling the plug and power button hold downs. No good.
The reset button will sometimes give a boot thru...

Some one else mentioned the pci-e version problem elsewhere. That might be the cause. AMD lists this vidcard as a pci-e 2.1 compatible with 2.0 .

I'm going to update the mobo BIOS to the last one. The update info only mentions newer CPUs...we'll see.

I wasn't planing on a mobo upgrade just yet...might have to.

Thanks for the ideas.

:?

So I've updated my mobo BIOS to 1002 ( dated JULY 2009 ). It ran and booted proper with my 9800GTX+.

Plug in the 5850 and it takes over or close to a minute of thrashing about before the PC boots thru. Over a minute! I had never let the pc kick around for that long with the older BIOS ( it may have done the same as with this one ). Once it comes thru the pc works fine...the OS ids the card. CPU-Z ids the card. Drivers install. Games run.

BUT... a whole minute of back and forth before a boot up?

There's talk of a BIOS update for the 5850 to fix some of the wide screen issues the card has. ASUS support site doesn't have any. AMDs site mentions a BIOS update will be available for that issue. No mention of us with old PCI-e mobos and boot issues.

I think I'll live with it for a bit and fool around with the MOBOs BIOS.

I guess this is a subtle hint to buy a new mobo.

:roll: :?

According to a page at the AMD website there should be a BIOS update available soon to fix a display port issue of some sort. No mention of PCI-e version conflict at all.

http://support.amd.com/us/kbarticles/Pa ... yport.aspx

No manufacturer site I've been to claims that the card is compatible with anything less than pci-e 2.0 .

In the mean time I got fed up with the unstable booting and went back to my 9800gtx+.

I may return this card for a refund! Use the money to buy a new mobo/cpu/memory combo....and get a card MUCH later.

I'm so disappointed by this issue.

:(

I've come to the conclusion that this generation of ATI vidcards may not be compatible below pci-e 2.0 . At the very least with this old Nvidia chipset...

Non of the manufacturer sites I've been to mention backwards compatability beyond 2.0....this card is 2.1!

Its my fault really I should have known.

Now to buy a new mobo and swap as much parts as I can over.

:? :x

Ok, maybe this is a dumb question....Do you have both Nvidia and ATI drivers loaded at the same time when you're doing the GPU switches? I think I remember reading somewhere that they don't play well together. Could that possibly be some of the issue?

Just asking.....

NAH...first thing I always do is delete video drivers BEFORE I install a new card.

Besides I was not even getting to the BIOS boot screens. Never mind geting to windows to cause sucha conflict.

Nope...its either the chipset is too old or the 5XXX are not that compatible with pci-e 1.x .
The only dumb question is the one that doesn't get asked!

Anyhow I got a newer mobo to try out this weekend.
I'll keep you updated...

:)

Update.... I got a "new" mobo. Not a new model by any means but all my components moved over no problem.

The new mobo Asus M4A77D. AMD chipset.

So I'm halfway thru installing my OS(s) XP is running fine the computer boot in a timely fashion!

So with this basic install the family can use the PC tomorrow.

Next on to games and bechies.

:D

So yeah that M2N-sli was just too old a chipset or something.

Now ASUS has released a BIOS update that " M2N-SLI BIOS 1103 Fix it may take much time to boot with ATI Radeon 5850 ". I missed this in June when it came out.

Their wording not mine. So a possible fix thru BIOS updates. Nice. Late for me but....

Also the M2N-SLI now actually supports some AM3 4cores with the new BIOS.


:D
