Not what you want to hear but you thought about selling the 9900k they are worth more second hand than their performance warrants, then buying a 5700x + mobo or 12600 + ddr4 mobo.

I should imagine that even with single channel memory you'll find that performance is stronger than the 7700K in the vast majority of games, so long as you have a decent graphics card and don't play at a low resolution.

so can only run my 2 16gb in b1 and b2 slots in single channel is this a problem?

You might want to check the motherboard pins and the CPU cooler mount.

i have read about bent pins or there could be a problem with the cpu or could be the MoBo dont no where to start

Yup, it could be all of the above and add faulty ram slots into that mix too, so start by taking your CPU out as Tetras says and check for bent / missing pins, you can also have a look at the motherboard PCB between the CPU socket and RAM slots for any scratches, check the RAM slots for any missing or bent pins, also look at the CPU itself for any scratches on the PCB part, I de-lidded an Intel haswell once, I got a tiny little nick on the PCB, back then de-lidding was done with a hammer and a vice, it never ran dual channel again.

After all of that, if it bothers you not being able to run dual channel then its a new CPU and/or Motherboard.
