Please Help when dual ram keeps 3 times beep

[Rendi Azmi]

i just upgraded my old macbook pro mid 2012 from 4gb ram to 16gb ram corsair (2x8gb)

it was fine when i put single ram 8gb in there, no beep sound at all and do perfect booting. also i make sure those both slot work perfectly with switch it back. it means no problem with the ram slots.

but, its getting weird when i put the dual ram 2x8gb in there. it causes 3 beeps. sound not good.

and absolutely im buying the brand new corsair ram from their official online marketplace. the review said it getting works and perfect fit with mbp 2012. so thats why i bought it.

pls help is there any good solution then please? thanks.

Try sending that RAM back to get a different set of chips.
If that also doesn't work, send back to get a refund of your money. It's not compatible for some reason (not unusual with Corsair RAM)
Purchase Crucial memory

Are you sure your new sticks are PC3-12800S that this MacBook requires?

Make sure your firmware has been updated using at least High Sierra 10.13.6

As the above user (DeltaMac) pointed out, Corsair has some compatibly problems, us Crucial, I heard plenty of stories here and other places that corsair does not always work, Crucial though I never heard of any issues.
