ga-990fxa-ud5 and evga 660ti WILL NOT BOOT!

[voices]

On friday i built my new system after triple checking all my connections i powered it up to find it would halt at the flash screen. (later after the raid screen)
SETUP:
GA- 990fxa-ud5 MOBO, evga 660 ti GPU, amd fx 8150 CPU, kingston predator 1866 2x4gb RAM, cooler master 850 silent pro PSU and a WD velociraptor 6gb/s  HD.
After numerous attempts to get into the bios including different keyboards and clearing the cmos i decided to start swapping components.  i pulled a evga geforce 210 from another computer and put it in. i was then able to enter the bios and update it to F11 i used it to install windows. i put the 660 back in hoping a bios update would help with no joy.  i pulled a asus hd 4870 out of another computer and put it in and it worked as well.  now i'm thinking i have a bad gpu so i put the 660 on a ASUS m4a79t deluxe (amd 790fx chipset) mobo and try that with no joy.  i then put the 660 on a GIGABYTE p43t-es3g (intel p43 chipset) mobo and it booted fine.  i also swapped a bunch of ram around which seemed to make no difference.
so all this testing tells me that i don't have any bad components but rather a compatibility problem.  if anyone could help me out that would be great.

If you put the video card in 2 systems and it didnt work even though it worked in the last one id say you have a problem with the video card.

the kind of problem that a different one of the same make and model would fix or a problem that would take a completely different card to fix?

[autotech]

Either or whichever is easiest for you. I had a 4850 that would work fine in 2 different puters but not in mine i did an RMA and got a different 4850 and it worked fine but it wouldnt work in crossfire so i finally just got a 4870 and that fixed both problems.

ok i will get a hold of new egg tomorrow and see what they can do for me.

one more question why won't it let me run my 1866 ram faster than 1333?

this build is seriously starting to piss me off.  seeing what is on sale and what isn't one day to the next and seeing that now i'm sort of stuck with what i have or pay more for something else is becoming super stressful.  plus my cooler master haf 932 advanced blue edition came with a bent thumb screw in the back that also bent the chassis and door.  this build has been cursed from the start i suppose. i hate to even think of what the return shipping will be on it.  i wonder if new egg will send me a shipping voucher.

[autotech]

If you bought it from newegg then contact them alot of time they will send you a return shipping label for free cant get much better than that.

i'm still a little confused about running 1866 ram.  every time i set the bios to 1866 it gives me an error when i boot and clocks it down to 1333.  do i need different ram or different settings?

[Ripshod]

I believe Predator RAM is dual rank, and according to my trusty chart:



The FX-8150 IMC is designed to run it at 1333. Anything over this I consider to be overclocking. Often though the IMCs will easily stretch to 1600, so give it a try

so i assume when the motherboard says it is compatible with 1866 (non oc) they are speaking for future compatibility?
why does it say in the manual "to support a DDR3 1866 mhz (and above) memory,you must install an AM3+ CPU first."  if there is more to it than that?

The CPU should work just fine at 1600 Mhz ,even Phenoms X6 work at such clocks.
The 1866 is as well supported with FX CPU-s.
You ve got the wrong RAM or BIOS updates may be needed.
