Help:With: DDR3 SDRAM DDR3 1600 (PC3 12800)
Hi
I am currently wanting to make my RAM (G.SKILL Ripjaws X Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9Q-32GXM)
Frequency to be at exactly 1600 but it is way lower. I am very ignorant in this matter first time with having the ability to manually adjust RAM speed. CPU-Z shows my max bandwidth at 667 and the frequencies ranging from the 4 sticks of RAM show 609MHz to 800MHz no where near 1600MHz. ROG system Information shows the RAM sticks #1 to #4 frequencies from 381MHz to 685MHz as the highest. This is horrible.
Please somebody explain to me how to adjust my RAM so it puts out 1600 MHZ; I already set in my bios to 1600MHz still made little to no difference.
Here is a link to the RAM that I own I bought from newegg:
http://www.newegg.com/Product/Produc...82E16820231569
My Specs:
MotherBoard: Asus Crosshair V Forumla Z
RAM: (32GB) G.SKILL Ripjaws X Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9Q-32GXM
CPU: AMD-FX 9590
PSU: 1200 watts
OS: Windows 7 Ultimate 64bit

Anybody had this simillar issue and resloved it? Any input is needed. Thanks.

in cpu-z click on memory tab and look at dram frequency if its like 800 just multiply by 2 because the memory is double data rate.

How are you sure that it is double that data rate showing? Where did you get this information and is this accurate?
My DRAM Frequency is 822.8 MHz So when I times 2 it, I get 1645.6 MHz
This make me not trust the cpu-z application. If it is suppose to be accurate it should show my correct Frequency etc... Not make me find out from another source that I have to (times x 2) that amount to get my real DRAM Frequency.
Are you sure about this?

DDR means "Double Date Rate", as opposed to older SDR ("Single Data Rate") memory types. DDR3 article on Wikipedia.
Your DDR3-1600 aka PC3-12800 (aka JEDEC DDR3-1600H) memory has a base memory I/O frequency of 800MHz (1Hz = 1 address clock cycle per second), but because it is DDR-based this rate is doubled to 1600MTps (1Tps = 1 Transfer per second) and it is sometimes even referred to as PC3-12800 (because, ignoring error correction overheads, 1 Transfer = 64 bits = 8 Bytes, while 1600MTps x 8 Bytes = 12800 MBps). People commonly misuse "frequency" in this context, firmware/software commonly makes this mistake as well. Good firmware/software (like CPU-Z) explicitly specifies base frequency units to minimize confusion.
And you won't see 1600MHz GPU-Z frequencies on anything slower than overclocked DDR4-3200, lol.

Ohh, all that is way over my head sorry, I am slow in this area.
Korth you said "And you won't see 1600MHz GPU-Z frequencies on anything slower than overclocked DDR4-3200 ?"
What does that mean?

Your DDR3-1600 is 800MHz and 1600MTps.
DDR4-3200 (which won't run on your motherboard) could have 1600MHz and 3200MTps.
What I was trying to say is that "MHz" and "MTps" are commonly used interchangeably, confusingly, mistakenly. Even though MTps is actually double the MHz when talking about DDR memory.
CPU-Z reports the correct values for your memory.
In the Memory tab, under Timings, DRAM Frequency shows current frequency (in MHz).
In the SPD tab, under Timings Table, Frequency shows all (up to four) possible configurations (in MHz) for each populated Memory Slot. Some of these will be standard JEDEC values, some of these may be faster EPP/AMP/XMP values. Your system will automatically select the fastest of these SPD profiles supported by your processor and motherboard at boot. I think this happens to be "JEDEC DDR3-1333H"
667MHz (1333MTps) 9-9-9-24-2N 1.50V. Your FX-9590 processor natively supports up to DDR3-1866, your CVFZ motherboard officially supports up to DDR3-2400, many people have overclocked these parts to DDR3-2666 speeds and beyond.
You can force your memory to run at faster settings by manually entering the frequencies/timings/voltages into your BIOS. Your G.Skill kit is rated for 800MHz (1600MTps) 9-9-9-24-2N 1.65V, there's no reason it shouldn't work at those settings, copy them right off of the CPU-Z reports and enter them into the correct BIOS fields.

Okay well the "9-9-9-24-2N 1.65V" which of this is the "frequencies/timings/voltages"??? and where at in the bios, sorry this is my first time doing this.
