Help with timings

Greetings all,

I just finished my first build in years. A lot of thing have changed in the time since I last built a rig, and I am feeling a bit lost. I bought the following:

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory
http://www.newegg.com/Product/Prod [...] 6820231303

XFX HD-577X-ZNFC Radeon HD 5770 1GB 128-bit DDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card - Retail

AMD Phenom II X2 555 Callisto 3.2GHz Socket AM3 80W Dual-Core Desktop Processor - C3 Revision Model HDZ555WFGMBOX - Retail

Combo again:

ASUS M4A79XTD EVO AM3 AMD 790X ATX AMD Motherboard - Retail
http://www.newegg.com/Product/Comb [...] mbo.333251

When I run 3d mark, it shows that 1.3 GHz is the frequency. I have gone into the BIOS and tried to change the frequency to 1600, but it won't load windows.

I see a lot of options to change change timings and voltages, but I'm not sure what to set them too. I did go into a page that looked like i could enter frequency, cas latency, ras to cas, ras precharge, tRAS, tRC, and command rate. I believe it also had a prompt for voltage, but it was all very confusing for me. ANY help you all can provide to help me set up an optimal system, with perhaps a minor overclock would be helpful.

The last system I built was 6 years ago with an AGP 4x slot, and I think I overestimated my abilities going into this build. Thank you all in advance.

The software may have been reading the voltages wrong. I would just stick with what the motherboards suggested. Unless there was some other problem you were running into?

I'm not running into a problem really. I just want the memory to run at the timings I bought them to run at. Is there a program I can use to show the true memory settings?

Your links are broke, but I figured out which RAM kit you have by the end part of the Newegg item number. That RAM is rated at 7-8-7-24-2N timings at 1.65v. That's the values that you need to manually set in the BIOS. Your motherboard owners manual will tell you how to change the values.
