So, I've got 2 motherboard and 2 graphics cards. I WANT to use my new XFX 6850 in my ASRock Z68 Extreme3 Gen3;
However, I couldn't get the damn thing to use the discrete card, not the integrate graphics. Even when I tried my old GT 240.
So I switched everything over to a P8P67LE that I also just purchased.
Same problems.... everything works, boots fine, loads up zippy quick with either card... right up until I reboot after installing the drivers. Then it gets to the Windows logo and locks up right before the login screen.
I've tried removing and reinstalling all of the drivers for either card several times on either setup... Anything I could've / did miss?
1st try to login in safe mode
then uninstaller drivers
the proble might be with the drivers get new correct version(drivers ) from the internet
normally this happen when the correct version of driver are not installed...
Hi, yes boot into safe-mode uninstall drivers if it still does the same boot into safe-mode again and go to device manager and under monitors delete all listed monitor(s) restart it should be fine, reinstall drivers
So I've tried both of those solutions; First ran through my BIOS and doubled checked I have all the correct settings/
Also logging into safe mode and then uninstalling the drivers, works fine up to that point. Restarted, boots up and logs in without any drivers; then new software is detected, windows attempts to install some garbage, then I run the Catalyst installer thing; it finishes, then I restart again, same issue.
I feel like it might have something to do with UEFI and having a discrete card? That's the only similarity I can pick out that I've never encountered before.
For clarification, the Z68 does not have integrated grapics, so that wasn't your problem.
Sounds to me like your memory settings are incorrect in bios. Check sticker on your dimms for correct voltage, speed and timings, then set those in bios manually.
This would cause all the problems you mentioned.
Also, if you didn't plug in the pci-e power cables to your video card, it's not going to work. And make sure your monitor is plugged into the video card after you connect it's power cables, not the motherboard.
Bad memory timings may cause my issues, but they would also cause many other issues i'm not having, so i can rule that out.
My PCI-E cables are obviously plugged into my video card... or it wouldn't turn on at all.
Thanks for the advice, I def think I'm going to do that when I get home in a few hours... I'll post back when I get some results.
Memory timings is automatically configured by the bios it's not necessary to manually do that, but it's worth a try.
And if nothing works as suggested format and reinstall windows.
I have only seen 1 out of 4 I have put together that do. Especially if you have ddr3-1600 at 1.65v it will default to 1.5v ddr3-1333 on auto. Mine actually defaulted to 1066. Same problem on my friends machine with DDR2. Her board was on auto which was 667/1.8v. She was having problems with it, I checked it was 800/2.0v ram that she had. I raised the voltage and speed and walah it worked perfect.
I also personally had a machine that would not load windows it would get a stop error. Same issue, the ram voltage wasn't high enough.
Yes i agree with ddr3 1600's you'll probably have to set the timings manually especially when the motherboard does not natively support ddr3 1600, but he is running ddr3 1333's which his motherboard natively supports so no need to manually adjust the timings, voltages etc.
