Asus P5P43TD PRO doesn't POST with new HyperX 1600 RAM

I wanted to get more RAM for my older PC (CPU Q8400 on Asus P5P43TD). The motherboards' specs say it works with 1600Mhz RAM so I bought 8GB of Kingston HyperX Blu (Kit 2x4GB), code KHX1600C9D3B1K2/8GX.

I already have the latest version of BIOS but it doesn't POST for the life of me (fans are working, black screen, no beeps). I tried inserting only one stick (tried all 4 slots). I tried both sticks in slots 1 and 3, both sticks in slots 2 and 4, still no luck.

When I put back my old RAM (2x2048 Kingston Value RAM) it works just fine. Everything in BIOS is set to AUTO. Back to the drawing board for more mining. I tried increasing the RAM voltage to 1.65v as specified on the new sticks without success.

I'm sure the memory is fine but I just can't get it to work. Any suggestions are greatly appreciated!

My existing RAM is two sticks of good old Kingston Value RAM at 1333Mhz. Looks like the motherboard isn't accepting the new HyperX RAM in any configuration, not even mixed with the old RAM. Oh well, it seems I'll have to return them and try to find some old Value RAM instead, possibly only a couple of 2GB sticks to make sure they are compatible.

How many MB/chip is the new RAM vs. the old RAM.

DRAM packages above a certain density won't work with P43/45 chipsets.

You should be able to find compatible memory on Cruical's memory finder and OC it to 1600. (If it works at 1333@1.5v, there's a pretty good chance that it'll work at 1600@1.65v, especially if you slack the timings.)
