Windows 7 - RAM Timings

Hi, I've got 2 1600MHZ Patriot Sticks, The latest 4GB 2x2gb pc3-12800 1600mhz sticks I installed are running at a slower timing as my other 2 sticks at the minute. Do these need to be overclocked?

or underclocked rather?, (So they all can run at 1333, or 1600mhz even)
any experiance
thanks

Sorry, you can't OC specific RAM slots. All the RAM wil default to the lowest "speed" of the RAM installed. Unless you install two more 1600MHz sticks, it will all run at 1066MHz. Also you could remove the two 1066MHz modules and get your 1600MHz at stock speed.

are there 2 ram slots on my motherboard capped to 1066mhz??
my motherboard is gigabyte 890gpa-ud3h, both sticks have labelled on the Ram package PC-12800 1600mhz.

are only 2 sticks on my board allowed to run at 1600mhz? not really sure why this is, looks like I can't use 2 of my sticks at the minute

Looking at your image, it suggests that you don't have a matched set and they are 2 different types of ram with different latency's etc. as a result as has been previously suggested at best you would only get the lower speed.
your Bios should give you the overall set speed or use something like CPUZ which will again give a total set speed.

It is a limitation of all motherboards. RAM will run at the speed of the slowest you have installed, regardless of the speed of any other RAM sticks or what slots you have them in. You will get the 1600MHz only if you:
1. remove the 1066MHz RAM
2. Replace the 1066MHZ with 1600MHz.
the BIOS will treat any RAM you have installed with the 1066MHz as 1066MHz, no matter what the label reads.

this is the new sektor5 ram i bought of PCCG a couple days ago
this is the speed its running at, my old patriot memory was running at 1600mhz previously,

it has designed for Intel, and ive been told intel ram isn't fussy with AMD. any assistance?
anything in BIOS i can do to OC the timings to where they should be, or should I return this memory (most likely sell it on OC boards) and buy the patriot memory I'm using atm
thanks

the name of my ram states Patriot 1600, it should be running at 1600mhz this is absurd. I'll have to return these sticks if no one has an advancement. Ill be buying the same sticks I previously had in my system (waiting for reply)

this is the speed my rams running at now
is this Slow compared to where it should be?
shouldnt my mhz be at 1600mhz? (I believe this RAM i have running is also intended for Intel chipsets)
Can anyone recommend me RAM that runs at 1600mhz SOLID for AMD chips compatatible with my GB 890gpa-ud3h
motherboard.
appreciate it thanks

Just because they are rated to run up to 1600 Mhz, doesn't mean they will. If you have slower memory in your computer, then your 1600 Mhz sticks will be running down at that speed. This is the way it is and always has been. It is not a defect, nor is it something to be worried/angered/care about. There is nothing absurd about it.

Do this, Remove the 1066MHz sticks and see what you get. Put them in a drawer. Buy 2 more 1600MHz indentical to what you now have, put them in.
In BIOS set CPU NB FREQ to X11
CPU FREQ 200
