Cannot reach 1600 ram speeds or 4000 HT

[SevenCorpseMeal]

I just build a new system over the holidays. System setup is Amd Athlon Phenom II 955 Black edition deneb 3.2, Corsair Dominator 1600 DDR 3, ATI Sappire 5870 MSI, 790FX GD70 Motherboard and a 650watt power supply I am wondering why i cannot run my Ram at 1600 and cannot get a Fbs of 4000. if i bump up the ram to 1333 it runs fine sometimes locks up after about a day and half of leaving it run. i do not over clock much and the only thing i did was jump up the ddr voltage to 1.65. when i run prime 95 on 1333 it will run all night without any problems, the minute i bump it up to 1600 it locks the program right after i start it. How do i achieve 1600 speeds and 4000 Ht, Please help Thanks

Check if your CPU or your mobo supports DDR3 memory up to 1600. As an example my intel core i7 860 supports only up to 1333.

Ya my Motherboard supports up to DDR3 2133 OC, the ram is DDR 3 1600

Okay, this seems to be the new fad and a popular question around here these days. Everyone wants 1600mhz memory all of a sudden, and there is really no reason to have it unless you trying to hit big overclocks with your processor.
Raising just the speed of your memory, or the hypertransport bus won't really gain you anything, except unstable memory. You will gain a lot more real world speed, or at least it will "feel" faster if you can simply get it to run with lower timings.

so your saying i should just stick with 1333 and 2000Ht, and i wont notice a difference, i have no problems with that, i just want to know why i cant reach these speeds when i baught everything to get these speeds, not a big deal i just want to get what i payed for you know

what do i need to do to hit higher clock speeds on the cpu, and obtain 4000Ht and 1600 ram speeds, i am new to overclocking but i would really like to do this just to make sure my system is capable of reaching these speeds
