I downloaded gaming 7 f20d bios from gigabyte and this time is working fine, xmp works and fan control save my settings, system is stable, much better than f20b
Hi I have a question. I saw a lot of updates (and eufis) for many mainboards but i cant find any update for GA-P67A-UD4-B3.Is any uefi version for this mainboard? I will be gratefull for answer.
Hello, I bought myself here again to seek some help on the memory issue with my Z97MX-Gaming 5. I bought two Corsair Vengeance Pro - 16GB DDR3 2400MHz C11 Memory Kit (CMY16GX3M2A2400C11R) to replace the dying 1600MHz ram.
However, this memory modules are not listed in the QVL. The motherboard was able to run XMP with one or two sticks in DDR3_1/DDR3_3 or DDR3_2/DDR3_4, but it didn't work on all sticks in four slots. 2133MHz 10-12-12-31 works fine, but sometimes the compression artifacts would show up in the viral videos at few times. Setting to default speed makes the artifacts go away. The DDR voltage is adjusted to 1.692V automatically as it was specified to run at 1.65V which I'm completely fine with it. I still am using the beta bios f7c and hoping if there will be added compatibility for the new memory kit in the bios.
You bought two RAM kits that are designed to be run on their own (i.e. 2 DIMMS only) when XMP is enabled.
To run all 4 DIMMS using the XMP profile you will likely need to manually set the tRFC value close to double what is in the XMP profile to get the motherboard to POST with 4 DIMMS.
You may also find that the tertiary timings are too tight so loosening them may also be required.
A BIOS "fix" is unlikely as the motherboard is doing what is expected - reading the XMP profile and trying to apply it to 4 RAM sticks instead of 2.

Absolutely, it is not guaranteed to run at the advertised speed depending on how much IMC can push for all 4 DIMMS. My 5675C simply cannot do XMP 2400MHz at default VCCSA/VCCIO voltage, but still happy to run at 2133MHz (9-11-9-30) or 2200MHz (9-11-11-31). Tighter timings at both frequency makes up the loss of latency and speed equivalent to 2400C11, so I am happy what I got away with 2200MHz tighter timings + XMP profile enabled.
I really don't see the point of making a BIOS fix since the motherboard's DRAM VR and CPU's IMC is working fine as intended, so any improvements or bug fixes in the new beta BIOS will be greatly appreciated. Thank you for replying to my post with several helpful tips.
P.S. About the issue of compression artifacts, please disregard it. The main culprit is hardware acceleration, not memory ram. Already tested on MemTest86 7.1 and Windows Memory Diagnostics at several times.
