How to manually set up your RAM speed, timings and voltage

Is your RAM running at the speed it should be?

How to Manually set up your RAM Speed, Timings and Voltage

 

Introduction

When a system is first put together, or the BIOS is reset, certain settings will revert to their stock state. This can mean CPU overclocks are reset, fan speed profiles may be lost, hard drive boot priorities may become scrambled, and also the RAM will reset to the default speed of 1333Mhz (on DDR3). We show you how to manually adjust the memory settings to set it to the rated speeds set by the manufacturer.

 

 

Method

First things first, you need to check your memory specifications. To do this, you can either check online from the retailer/manufacturer that you bought the Memory from, or take out one of the sticks of RAM and it will say on the label. Take note of the memory speed (2400MHz for example), the timings (10-12-12-31 for example), and the voltage of the memory (1.65v for example).

Before touching any setting in the BIOS, it would be advisable to download CPU-z here, and under the ‘Memory’ tab, double check what you have your RAM set to. Remember, as ‘DDR’ stands for double data rate, you need to double whatever value it shows next to ‘DRAM Frequency’. For example, if 666.5MHz is showing, then the RAM will be running at 1333MHz. Now, if you’ve bought 2133MHz memory, then you’re losing a considerable amount of speed in not having it set to the correct values.

Now, getting into the BIOS should be a simple case of tapping delete as you turn the system on. It may be another button on the keyboard, so if that doesn’t work, check in your motherboard manual. Once into the BIOS, find your way to the ‘Overclock’ settings and once there, look for memory settings.

From there, you need to look for a setting ‘DRAM Timing Mode’, and then ‘Advanced DRAM Configuration’ which will take you to another screen where you will be able to manually input the values for the Memory Timings. Usually, these will default to 9-9-9-24, and a lot of 1600MHz memory already uses these timings, in which case you won’t need to change anything here. However, with higher memory speeds such as 2133MHz, the timings will often be a little higher, so you will need to manually change them. (its worth remembering each board can be worded slightly differently but we are sure you will be able to work it out)

After doing this, go back to the previous menu and look for DRAM Voltage. This will most likely display ‘Auto’, in which case, you need to change this to your specific value. This will most likely be 1.65v, 1.5v or maybe 1.35v for DDR3, but it may be different if you have low voltage RAM.

Finally, look for the DRAM Frequency and then on the drop down list, choose the correct speed for your RAM.

You can now press F10 to save your settings and reboot the PC. It should start up normally (maybe even a few milliseconds faster if you’re lucky!) and then you can check again in CPU-z to make sure the settings have saved correctly.

It may be worth checking with a benchmark program to make sure your system can support very fast memory. 1600MHz and 1866MHz should be fine with most systems, however, it is worth testing anything higher with something like OCCT, some older CPU's just can not run very high memory speeds and others need a little more tinkering in the BIOS to get them to play ball. If you have any issues or questions, feel free to ask on the OC3D Forums.

Brilliant guide for beginners. Will definitely refer friends and family to this if/when they eventually want to try their hands at basic overclocking.Quote

Anyone know the bios settings for 4 4gb vengeance 1866mhz ram on a gigabyte z97x gaming 7 with an i5 3.5ghz processor. I am having trouble getting it to start up in anything other than 1033mhzQuote

Its written on the side of you ram sticks and in this guide dude.


Are you pressing F10 to save your bios settings when you exit?Quote

I am attempting to adjust my BIOS settings to adjust the RAM speed for new sticks I have installed, but my BIOS seems very basic and doesn't allow me much customization. I read the article on this website that shows how to manually change RAM's speed, timing, and voltage, but my BIOS does not allow for it. Please help!!

I have a Samsung SF510 laptop and I am attempting to upgrade to 8gb of RAM. The compatible RAM for my machine is: http://www.crucial.com/ProductDispla...&storeId=10151

I bought these, thinking they'll work because they have the same specs: http://www.amazon.com/gp/product/B00...ilpage_o02_s00

But when I installed one new stick with an existing (2 gb) stick, I get the BSOD with Win7 with this error: PAGE_FAULT_IN_NONPAGED_AREA

Thanks again for any help!Quote

Laptops are very specific dude - you should probably just run matching sticks so try removing the original 2gb one, also 99% of laptops wont let you change ram speed.Quote

I need help. I bought Vengeance® Pro Series — 8GB (2 x 4G DDR3 DRAM 2133MHz C11 Memory Kit (CMY8GX3M2A2133C11)http://www.corsair.com/en-us/vengean...8gx3m2a2133c11. My MOBO is GA-F2A88XM-HD3 http://www.gigabyte.com/products/pro...px?pid=4727#sp. I tried to enable AMP since I am using an AMD platform. However, it didn't set the speed to 2133 MHz so I did it manually including the timings of course. The problem is that it's not stable. Whenever I try to run Prime95 test on it, it comes up with an error message that says something like "FATAL error: Hardware problem detected..." Games would randomly stop as well and I got 2 different BSODsQuote

Those stick's dont support AMP you need AMD ram sticks or some patriot stick's support it (patriot actualy makes AMD's ram sticks)
AMD chips can be picky with ram try running @ a lower speed with tighter times.

Oh and stop useing prime 95 its out of date and pull's way to much power with AMD chips use occt http://www.ocbase.com/Quote

I need help with something. I followed the instructions and set the overclocking right. But the DRAM Frequency won't let me run on anything higher than 1333Mhz. Whenever i try to crank it up to 1886 (which is the speed of my RAM sticks) the CPU overheats.
Could this be my MOBO not being compatible with 1886Mhz?

My MOBO: ASUS P8H61-M LE
My RAM: G.SKILL F3-1866C9D-8GAB Ares Series 8GB

Please don't post multiple times in a row

If not, what else could be the problem?

It doesnt overheat my bad. But the entire computer wont start up and i get stuck at a black screen where it says "overclocking failed, press F1 for setup" and that takes me back to the bios. After giving that a few tries, thats when it overheats.Quote

Did you also set the timings? If not then that's probably why it fails to boot. Set the correct timings and speed and it should work. However even if setting that does not work, the board is rated to only support as high as 1333mhz. You at most will probably only get to 1600mhz and have to manually enter timings till it finally boots. If that doesn't work, i'd say go down to 1333 and then manually set the timings at a low setting to get the most out of the memory.Quote

I don't think your motherboard can run 1866MHz memory this is from the ASUS website

2 x DIMM, Max. 16GB, DDR3 1333/1066 Hz Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture
* The maximum 16GB memory capacity can be supported with 8GB or above DIMMs. ASUS will update the memory QVL once the DIMMs are available in the market.
* Refer to www.asus.com or user manual for the Memory QVL (Qualified Vendors Lists).
* Due to OS limitation, when installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Install a 64-bit Windows® OS when you want to install 4GB or more memory on the motherboard.

I have the same sorta of issue with my ASrock B75 motherboard even tho ASRock does state on there website that my motherboard should work with 1600MHz memory.Quote

Thank for all the answers. I feared my motherboard wouldn't support more than 1333Mhz. My computer works fine with more RAM now!...But will i notice an improvement if i try change the frequency up from 1333Mhz to 1600Mhz? Even if my motherboard doesnt support it?
Because i've found that my two RAM outlets can take up to a maximum of 800Mhz eachQuote
