Greetings,
I've basically swapped my Gigabyte 3870 DDR3 version for a DDR4 (same card just different memory) version. After running some tests in 3Dmark and playing a few games all seems to be fine but recently I've had quite a few crashes. The ATI CCC (catalyst control centre) crashed quite a few times, possibly while saving data and I think it's stuffed something up.
What I need to know is. is a PCIe speed of 142 MHz safe or not? Sometimes this goes up past 200 MHz and lower. I've always thought this should remain at 100MHz, or 110 max. There is also a PCIe clock which states it's at 100MHz. I gather this is not the same as the PCIe speed? Or is it? Currently freaking out as the numbers do not seem to match and for some reason setting the default speed does nothing in AMD Overdrive.
Notes:
BIOS setting for PCI speed is on Auto.
Didn't update the driver as I thought 3870 replacing another 3870 would be a no issue (only difference is memory).
Motherboard is a Gigabyte 790FX-UD5P (790FX chipset uses DDR2 memory)
Processor is a 9950 AMD Phenom.
Any help is greatly appreciated.
