How do you get RAM to run at full capacity?

[BootlegUsher]

Hello, I recently purchased DDR3 1600 RAM and my motherboard supports this speed, when overclocked.
For example 1600(O.C.)/1333/1066 ECC,Non-ECC,Un-buffered Memory will be in the specs.
From what I understand this means that my RAM will be set to 1333 by default, and I will need to go into the BIOS to change the speed.

Will it simply be a matter of selecting "1600" or will it be more like this:

If it is that^^^ then I will need further explanation please.

Just because memory CAN run at those speeds doesn't necessarily mean you need to.

i recently bought some patriot viper ddr3 1600 4gb for my asus m4a785td-v evo

they ran at 1066 when first installed with 1.5 volts, i had to go in my bios under jumperfree configuration and do two things.
first i upped my voltage to the recommened spec's (in my case 1.9 volts) and then changed the clock speed from 533 to 800

I new fairly new to this stuff but it appears to have done the trick for me on my board

most good ddr3 can run at 1600@1.5 v so yes normally all you have to do is set it to that and away you go

I always just set up memory settings manually at the speeds, timings, and voltages specified. That way there won't be any confusion there.

lol wtf ram you got which needs 1.9v johnny.
depends what mobo/cpu you got bootleg...
if i5 for example base clock and ram multiplier make it up.

160 base clock with a 10x ram multiplier is an easy way to get 1600mhz

these bad boys Newegg.com - Patriot Viper 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit Desktop Memory Model PVS34G1600LLK - Desktop Memory


they ran stock at 1.5 volts but my computer would freeze up every once in a while

ouch 1.9 for 1600, but those timings are pretty sweet.

Damn thats crazy. Yeah to get my i5 OC stable I need to bump my ram voltage from stock 1.5 to the next step which was 1.56.
I dont know why this is but as soon as I did my OC was stable for as long as I tested in prime95, which was like 21 hours I think.

I have my dram at a nice 1.20625v and run my RAM at 1523Mhz. (rated at 1600Mhz). G.SKILL F3-12800CL9T-6GBNQ. My timings are at 8-8-7-24. It is pretty annoying though that it seems with a lot of brands of ram you have to overclock it to run at its rated speeds. I think most DDR3's on an x58 with an i7 will stock at 1333.
