B150 Gaming K4 & High-end graphic cards

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Dear all,

I'm writing this post to share my experience : Had problems with my newly bought B150 Gaming K4 (with core i3-6100) and my graphic card "Sapphire Tri-X R9 290 4GB GDDR5 OC(UEFI), New Edition"

to explain the issue =, Here is the ticket I opened at Sapphire support :
Just bought my new setup ( i3-6100, RAM, Asrock Fatal1ty B150 Gaming 
K4). I installed W10 64b, installed AMD drivers (latest found on AMD 
support site), installed provided drivers (CD that came with MB) and when 
launching a game (tried WoW and GW2) I got driver crash every minute 
(randomly). I think that the English message is "Display Driver Stopped 
Responding and Has Recovered" (French was : "le pilote d'affichage ne 
répondait pas et a récupéré"). Also a lot of BSOD.

So I installed W7 64 bits, same result (but no BSOD). What I did then :

1. Updated MB BIOS to latest version -> No effect
2. Uninstalled AMD drivers, reboot install drivers from Sapphire CD 
-> No effect
3. Upgraded drivers to latest version using Catalyst control center 
-> No effect
4. Reset MB UEFI to default settings -> No effect

2 days ago, I was using the same graphic card on an old Intel Core 
I5-760, on a Gygabyte GA-P55-USB3 MB with 16 GB DDR3 RAM and never had an 
issue.

Sapphire answer was pretty simple : buy a more powerfull PSU, at least 750 (I have a Corsair HX620). Then I asked them why then it was working on my old setup.

I finally found the solution by myself. The B150 Gaming K4 as an extra molex connector. User's manual says that (ftp://europe.asrock.com/Manual/Fatal1ty%20B150%20Gaming%20K4.pdf  page 23) : "Please connect a 4 pin molex power cable to this connector when more than three graphics cards are installed."

I have only one GC but, as I had no lead, I plugged my PSU to this connector. And that's when the "miracle" happened : issue was solved.

So, ASRock TEAM, if you read this, please update your user's manual because with 1 GC that consumes a lot of power, you need to plug this molex connector.

Hope that this post will help someone :)

	Thanks for posting this as it is a common issue posted here with cards that pull a lot of power from the PCIE slots and have usually the two 6-pin or a 6-pin and 8-pin PCIE power sockets on the card itself. The molex provides additional power to the PCIE slots for just this purpose. Newer, power hungry cards.
