Random BSOD Help please?

Hello all, it seems I'm having a bit of an issue here. I just upgraded my graphics card to a R9 290 and am loving it but just yesterday I've been having these random blue screens when i sometimes load up youtube. I just disabled hardware acceleration and all but when I looked up the mini dump is said it was due to and ATI system thing. Any ideas? And also is hardware acceleration even worth it? My web pages seem to be loading faster with it off xD

Also CCC 14.4 and no overclock on GPU atm. Games work fine at full load and only ever reach 70C.

lots of people have been reporting this same error. It is a bugcheck raised by the graphic driver. It only seems to happen on
overclocked versions of the AMD card. It also seems to happen to people that have power limited power supplies. It also seems
to happen to people that have a BIOS that is overclocking the PCI bus.

So, check your power connections to the card, make sure your lines are well connected and if you have a modular power supply and it is multi rail, make sure each modular connector from the power supply to the GPU is on a different rail.
- also check to make sure your BIOS does not try to overclock your PCI bus from 100 MHz default. (I have seen some set at 103Mhz)
(bad news to run a overclocked card on a overclocked bus)
- you might also check to see if there is a BIOS update for your GPU. (I have seen some cards come out with updates dated in june 2014)

most people have reduced the overclock or returned the cards or we never heard back on what the final solution was.
My best guess it that the card detects a internal error caused by power and generates a bugcheck in windows.
windows displays it as a Unknown bugcheck code.

note: pci slot = 75 watts
8pin connector #1 = 150 watts
8 pin connector #2 = 150 watts

total 375 watts available to the card from the power supply.
assume 80% efficient power supply unless you know the brand.
you might want to add up the power requirements of your system and check it with the power output and efficiency rating
of your PSU. Sometimes you just have to upgrade the PSU when you upgrade the GPU

My card is the Sapphire R9 290 And my PSU is a Corsair 750W fully modular supply. I've checked the power needed for my full setup and this should be completely fine. Although one question, since this card used a 8 and 6 pin can i just use one line or should I connect two for it? I'll check my bios in a little bit just in case for both of your suggestions..

So no Bios update for this card. Also what I've seen is that after disabling Hardware Acceleration on Chrome it hasn't happened again yet. Is Chrome known to do this?

johnbl · Aug 10, 2014

if the GPU requires 2 connectors the 8 pin should supply 150watts, the 6 pin should supply 75 watts and the motherboard should supply 75 watts.
the power supply should provide the 2 connections on different rails from the power supply to the graphics card.
rather than 2 connectors spliced off of one rail of the power supply. (2 separate connectors going to two separate locations in the power supply both the 8 pin line and 6 pin line should be connected or your GPU will be underpowered)

It ended up being google Chrome and the ATI Driver clashing, I did take your advise though and plugged in my GPU with two rails. Thanks!
