RAM Timings

[manolz]

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

 

[manolz]

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)

 

[manolz]

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.

 

[Britton30]

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
Mem clock/Manual, X8

When you buy ram, it often does not run at the stated speed out of the box.
For safety and stability reasons, motherboards are built to down clock the ram, if necessary.
Your ram will run at 1600 MHz, but you have to change the timings in the BIOS.

If you look at your CPU-Z, it will give you the timings that your RAM will run at.
Notice the timings, frequency and the voltage that it recommends.

In my example, when I bought my RAM, it was advertised as 8-8-8-21, DDR3 1333, 1.5V.
Every motherboard I've tried it in, runs it at 9-9-9-24, with is great, because if it ran at the advertised 8-8-8-21, it would run at 592 MHz or double the data rate, 1184.

The CPU NB Freq only goes up to 10
my CPU Freq is set at 200
I went along to the DRAM freq and increased it to x8.00 to run at 1600mhz, my CPUZ shows the ram speed it's running at.
Correct me if I'm wrong but my RAM still isn't running at 1600 (It's running at 800mhz I believe?)
Thanks, I'd like it to run at at least 1333mhz.
Also, You were saying how the RAM is running at 1066mhz and to remove those sticks, The RAM i've purchased is 1600mhz (PSD32G 16002 1600mhz CL9), whys is running so slow?
Do I have to discard all my sticks and buy new ones to run into the same problem again?, Can I OC?
thanks

 

[manolz]

my max bandwidth is PC3-8500F (533mhz)
whys this?

 

[manolz]

any comments?

 

[manolz]

If I can get some advice ASAP would be appreciated, I need to know whether I need new RAM that will run at the timings listed (AMD RAM) or If these sticks I have currently can be made to run at 1333 / 1600mhz speeds (their both 1600 mhz sticks)
thanks.

Ok

here are my RAM timings for my OLD ram, Patriot PSD32G

here is my everest benchmark

my questions at the moment are.

is this ram i'm running now currently running at 1600mhz Properly?
If so, Should I buy another 2 of the same identical sticks i'm running now for my upgrade?

The above screenshots in my previous posts are results from the sektor5 sticks, (they're not running at full capacity)
any advice with what to do would be great

if these sticks (psd32g) aren't running at their full speed i'll happily buy new sticks (8gb,amd)
seems i'm running into too many complications, these sektor5 sticks aren't putting out 1600mhz, and i'm unsure as to whether these patriot sticks are putting out 1600mhz either so i'm happy to buy compatible sticks that will do the job without bottleneck
feedback is appreciated, if i could get some direction sometime today it would be great so i can get to work with ram for my pc

Manolz, you have a AMD motherboard. Your memory controller is in your CPU. The memory controller sets the speed of the ram. An AMD system will set your frequency at either 1066 or 1333 automatically. The only way to make it run faster than that is to overclock your system which can damage the memory controller and other components in your system. When you look at CPUz the memory tab shows what your ram is running at now. You have DDR ram which means double data rate. So, if the memory tab in CPUz says your ram is running at 533, that means it is at 1066 (DDR 533 X 2 = 1066) You said yourself that your max frequency is 533. Max means that is the fastest it will run unless you overclock your ram which I am not going to tell you how to do. The problem is not your ram, it is your memory controller. On the side of the sticks of ram are the timings and voltage. Read those and set your voltage at what the sticks say. I think your ram voltage (Dram voltage in your bios) should be 1.65 but look and see. Your motherboard has set the voltage at 1.5V. I believe, if you change your dram voltage to 1.65 and set your timings at 9-9-9-24 that will be as fast as your system will run it without overclocking. As has been explained to you by several people here, just because your ram is rated at a certain speed does not mean your motherboard will run it at that speed, what it means is that the ram is capable of those speeds not that your system will run it that fast.

Ok thanks for the reply, I'll follow these steps and report back.

According to the screenshot of CPUz your ram is running at 1600. remember it is double data rate so multiply the frequency X 2.
