Unlike the three other deals earlier today on what sounds like the same Corsair Vengeance RGB Pro 32GB 3200Mhz RAM, this is the CMW32GX4M2C3200C16 model with tighter timing (16-18-18-36) and at least in my case, confirmed compatibility with my MSI X570 motherboard.
Looking online, this particular set is still running around the $290 mark so Amazon AU is doing a decent price this time. Note that it is "Ships from and sold by Amazon AU" - ie. not Amazon US via AU but actually fulfilled locally.
Interestingly this only came to my attention as I was researching and it's actually the same item as what I previously posted a few months back but fifty dollars less: https://www.ozbargain.com.au/node/475986
EDIT 30/11 Unfortunately the price has gone back up to $266.96 + delivery as it's no longer fulfilled by Amazon AU.
yup.. this is the Corsair RGB Pro RAM which works with my ASUS Prime X570-P motherboard - if you have or are buying an AMD CPU and motherboard be very careful which RAM you buy - it is almost essential to check the manufacturer's web site and look at the qualified vendors list of which RAM has been tested to work successfully with the motherboard.. otherwise you're going to be doing a return of the RAM after the end of the sale period.
