[SOLVED] Running DDR4 3200 on a Gigabyte B460 MB

[kaddazza]

Hi,

I recently bought a B460MB for an i9 10900 CPU. For ram I picked G.SKILL Ripjaws V series Black DDR4 32GB (F4-3200C16S-32GVK). After assembly it wouldn't POST, with the DRAM light on the MB solid red.

Is this ram not compatible? The vendor has other 3200mhz ram listed as compatible with that MB. I ordered some replacement 2666mhz instead, after assuming it's a compatibility issue. I've never given much weight to the QVL lists from MB manufactures before since they are so restrictive, but was this incompatibility something I could have foreseen because I didn't match up the type of ram with the MB correctly? Just trying to learn if I did make a mistake how to avoid it in the future.

Thanks!

Which B450 model?
Did you check that the RAM was installed properly?
Did you try on different slots?
Reset the BIOS to default and try again.

Gigabyte B460 AORUS PRO AC ATX

I bought 2 x 32gb of the 3200mhz ram. I tried each dimm individually in each MB slot. So fairly confident the ram isn't doa since both had the same trouble.

Reset the BIOS to default and try again.

No luck.

Max RAM speed for your MoBo and CPU is 2933 MHz. It is a limitation of the B460 chipset in general

Thanks. It's strange though, because if you google for "running faster ram than your mb supports" the first two pages of results seem to say that its fine and the ram will just perform less well than if your mb supported. I'm certain I've done this before as well without problems.

The 2666mhz ram got the mb past post, albeit the mb runs it at 2100mhz. So it seems running with higher spec ram than the mb supports does matter. I can't recommend this mb, it seems very poor quality.

Did you try to enable XMP with the 2666 MHz RAM ?
What exact reference of RAM ? Size of the sticks ?

If you go to the GSkill RAM configurator, you'll see that not a single B460 motherboard, from any brand, is validated to run above 2666 MHz RAM.
So running inside published specs does not make a motherboard "poor quality"
