Seller is "Gadget Lifestyle AU" but it is fulfilled by Amazon so returns and delivery should be very easy. According to this review the images of the DRAM chips show "DTDR" marked on them which means it's Hynix DJR. From a bit of googling it seems to be similar to Hynix CJR but scales further with voltage making it probably the best IC you can buy short of Rev.E and B-die. I can't guarantee it will be DJR, but it's still a good price for 3200CL16 memory.
Also Viper Steel for $99 too if that's your thing.
Should probably add 16GB (2x8GB) to the title.
