How To Check Memory Frequency
To check what your RAM frequency currently is. Of you looking to modify your current BIOS if your RAM is not running at the correct frequency. Check Frequency of RAM Module On Your PC With Specifications While counting the performance of a personal computer, Random Access Memory (RAM) has a very important place. It helps to improve the data transfer rate between hard disk and processor by acting as a buffer. As long as the RAM is DDR3, the system will adjust the memory clock speed to the fastest its and the SO-DIMMs are capable of. In other words, just buy some sticks of DDR3 RAM and you'll be fine. As best I can tell, this set should work just fine: G.SKILL 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1333.
We can easily check the details of RAM in Windows 10 using the Task Manager. The performance tab of task manager shows a majority of memory details including the total amount of RAM, how much is in use, committed/cached and paged/non-paged amount of RAM, RAM speed and frequency, form factor, hardware reserved and even how many slots are being used in the system.
You can also get these details from the command line. For this, you can use two commands, wmic and systeminfo. Systeminfo is a basic command and will only give a limited amount of information about memory while wmic will give the required details. Let’s see how to use these commands.
Quick Summary
- 2 Get RAM details using systeminfo command
Checking RAM details using WMIC command
- Type CMD in the Start Menu and open the first result you get.
- A Command Prompt window will open. Type the “wmic MEMORYCHIP get BankLabel, DeviceLocator, Capacity, informationSpeed ' command to have the complete information about your system’s RAM. And press Enter after writing the command.
- The three columns will be shown in front of you. BankLabel column will tell you which slots the RAM chips are installed in. Capacity columns will tell you that how much large each module is expressed in bytes. And the DeviceLocator is another entity to tell which slots the RAM chips are installed in.
- You can also get the MemoryType and TypeDetail column for your RAM to get some extra detail of your RAM. For this enter the following command.
“wmic MEMORYCHIP get BankLabel, DeviceLocator, MemoryType, TypeDetail, Capacity, Speed'. - MemoryType tells you the type of your physical memory. In my case, I get 24 which means DDR 3. And the value comes from TypeDetail member of the Memory Device structure in the SMBIOS information. I got 128 which says my RAM TypeDetail is synchronous.
- To get complete details about the memory modules, run the following command:
wmic memorychip list full
This command may not give you a user-friendly list of details but it will definitely give you complete details about the hardware.
Get RAM details using systeminfo command
Here is another way to find the RAM details for your system through systeminfo command.
- To find the total physical memory of your system enters the following command. The following command easily displays you the total amount of memory which is on your system.
systeminfo findstr /C:”Total Physical Memory” - If you want to get the information about the available memory of your system then run the following command and immediately get the result.
systeminfo find “Available Physical Memory”
Using commands is very handy and time-saving approach for any purpose. Just enter a command and you are done with what you want to do. So enter commands like I mentioned above and get detailed information about your RAM. If your RAM is not suitable or RAM is less, upgrade it to have a fast and speedy system to perform all operations smoothly and quickly. Thank you.

How do you know what Cas Latency your ram have?
(66 posts)I know how much ram i have, what kind it is and all that but how do i figure out what my cas latency is for my ram?
You have to look it up at the manufacturers website.
Chris,
Download and run this FREE program (CPU-Z version 1.48).
http://www.cpuid.com/cpuz.php
Kindest Regards,
Rick P.♦ :)
Rick, this is for CPU's. I don't see how it will give you the CAS latency numbers for your RAM.
@whs,
Gives info for all critical components.
(Download and try).
(NO) installation required.
Old up to date utility changed every few months with new version.
Been around for years.
Kindest Regards,
Rick P.♦ :)
Hmm, maybe. I myself am actually not very interested in the CAS latency numbers for my systems. It does not buy me anything knowing that. It is what it is. I know it is usually between 4 and 6. But that is not very telling. You need a lot more info to usefully apply the number. Would be different if I were out shopping for Dimms.
@whs,
Try it out.
You will be in for a Pleasant Surprise at what you don't know concerning your systems.
(NO) Installation.
Kindest Regards,
Rick P.♦ :)
You are both right! It is best to get your CL and other timings and voltages from the manufacturer, if you can. Also, it's not that useful to have the numbers for your installed memory, because there is not much you can do to change it.
However, CPU-Z does have a very cool feature on the 'SPD' tab that reads the JEDEC timing tables from the DIMMs. This information is useful when first setting up a new build-your-own system because the default timings may not be the best for your build. The 'Memory' tab in CPU-Z shows the current timing settings.
EDIT: and, BTW, CPU-Z can also show you the manufacturer's name and model number of the DIMMs (SPD tab) which will save you from opening your system to read the tiny print on the DIMMs themselves.
Rick, You were right. It does show the latencies. Now I know that my CAS is 5 (as I suspected between 4 and 6 - right in the middle). But I don't think that this new knowledge will disturb my sleep. lol
Thank you anyhow for the link. I'll keep it around.
chris,
Yes download from link I posted.
Unzip files to desktop and click on CPU-Z icon file.
Enjoy :) :)
Kindest Regards,
Rick P.♦ :)
Chris, This will be a Zip folder. You unzip it and double click on 'cpuz.exe'. That will give you the data - after a couple of minutes. Then click on the 'memory tab' where you'll find your CAS Latency. I don't know though what you are going to do with the data - other than look at it.
@whs,
It gives and (confirms) to us Builders a lot info when configuring a Custom Machine.
Remember on Builder Boards, the Bios has settings for changing about everything.
Kindest Regards,
Rick P.♦ :)
Rick, I know what it means to you. But I was wondering what it means to Chris (whom I know since a long time).
@whs,
Oh - Long time friend - Good.
May be he will reply and you can ask him.
Kindest Regards,
Rick P.♦ :)
@whs,
I see.
That must be one of the longest threads on the site.
A lot of questions and answers given by You and others.
Kindest Regards,
Rick P.♦ :)
shut up @whs.. i know i ask too many questions sometimes.. i'm embarrassed now..
Chris, you may ask as many questions as you want. No problem. But you must also read the answers - 3 times if neccessary.
Btw: With what PC did you finally end up?
i got a laptop.. out of nowhere my brother bought me one.. oh well. oh yea. by the way. lower the cas latency the better.. right? so for example cas latency 3 is better than cas latency 6. right?
Chris, Why your question. You asked whether 3 is better than 6 . right? -- and I said 'right!' to confirm. Where is your problem?
Ah. i have another question.. I was looking at rams and i realized that the memory that i'm using right now uses 1.8Voltage.. Will it have any problems if i get a 2-2.2 Voltage ram?
Chris,
Thousands of articles like this on net.
This is an old old one.
Let me see if can find something Better than below which will easily explain your questions.
http://www.dewassoc.com/performance/memory/cas_latency.htm
This one is a little BETTER.

This is a Good One

Rick P.♦ :)
Chris, 'because i don't get how cas latency work' - typing 'cas latency' into the google field should not be too much asked, even for a laze like you. But for the last time I give you a link because you are my friend. Next time you are going to do it yourself - OK?
whs.. i did research it.. but i still didn't get it before. jeez..whs..
OK, I'll make it easy for you. I assume you use the Internet Explorer. I want you to download and install the IE Spell Checker. That will do the following for you:
1. If you are not sure of a word's spelling, you highlight the word and right click on it. That will open a little context window where you can click on 'Spell Check'. This will come back with either OK or it will give you a list of possible correct words with which you can replace your word.
2. If you want to know what something that you do not understand means, you also have the options of lookup in the Webster or lookup in Wikipedia. When you click on one of those, the webpage explaining the word or expression comes up. This way you are sure you get to the right explanation.
Now go and install that. It will make your life easier.
wow, really slow day. can't believe i followed all the threads of whs and chris. it's like watching Harold and Kumar having a discussion! :-)
no offense guys!
i had another question. I was looking at rams and i realized that the memory that i'm using right now uses 1.8Voltage.. Will it have any problems if i get a 2-2.2 Voltage ram?
chris,
Most builder machines have a Bios that one can change memory voltage.
Most OEM machines do (not) have this feature.
ENSURE the memory you purchase is rated for the voltage that is specified for your machine.
As you tighten up the CAS, RAS and Latency timings, sometimes the memory modules need a small up-tick in voltage to perform well.
If your machine memory voltage is regulated to 1.8 volts, the memory modules you purchase MUST be rated and (Guaranteed) to perform at 1.8 volts.
Kindest Regards,
Rick P.♦ :)
ahh.. really.. hm.. that sucks then.. man so i can't get a memory that runs with 2.0 volt.. tx.
Chris,
Would (NOT) chance it at all.
HOWEVER THE GOOD NEWS IS; If you just change your memory timings without making other modifications to your machine, you will (never) notice a difference in your machine's performance.
Builder machines are built from the ground up, so to speak, with many differences besides just different memory modules so don't worry about the memory you already have.
Kindest Regards,
Rick P.♦ :)
what do you mean.. the memory that i have right now sucks.. i have 2 slots that have 256mb each and my computer's maximum capacity of memory is 4G's.. i was going to get 1 stick of new ram that has 1gig and i bet it will make a huge difference in my computer's performance..
chris,
I assumed you had adequate memory for your machine since your questions have only concerned memory timings.
The simple solution for upgrading your machine's memory capacity is to purchase MATCHED memory modules (Sticks) of the capacity you want with the (same) memory timings that you have now which are guaranteed to run at 1.8 volts which also appears to be the memory voltage your machine is regulated for.
You are by NO means doomed to never upgrade your memory capacity.
It is just matter of searching and finding the correct memory modules that are compatible with your machine.
If you post the make and model number of your machine plus the results from the CPU-Z program, we will help you search for and give some suggested memory modules which should work.
Kindest Regards,
Rick P.♦:)
raphoenix.. you are awsome.. thank you.. man.. but i'm kind of disappointed that i have to purchase MATCHED memory modules (sticks) .. dang it..so i guess i can't get a GOOD memory.. well. my model for my current memory is:

Chris,
Purchase (2) modules for a total of (2) Gigs.
This will (max) out you Asus Mother Board and HP Allowed Specs.
There may be other memory modules which will work but I looked up your computer model number on the kingston site plus cross referenced memory part number to newegg.
You may purchase from either Kingston or Newegg with only a dollar or two difference.
Kindest Regards,
Rick P.♦:)
so you're basically saying that i can only get a memory that's PC-2-3200?
chris,
On the HP Pavilion Slimline s7310n PC, just click the newegg link I posted and purchase (2) one gig sticks of memory.
Your computer will fly like a bird for a very small price !!!!!
Memory timings of 2, 2. 2, and 3, 3, 3 etc. MAKE NO DARN DIFFERENCE IN THE PERFORMANCE OF YOUR MACHINE.
MEMORY CAPACITY IS WHAT COUNTS ON YOUR PARTICULAR HP MACHINE.
Order Tomorrow :) :)
NO more 'this sucks' statements UNLESS you want to build a $2500 custom machine.

Ok. I gave you the answer in above postings so now purchase some memory if your budget permits.
Read orange spec sheet on this memory product.

ahha.. i've got it.. i've concluded that if you want to know what kind of memory you need to upgrade, you first need to know how much memory your motherboard supports PER SLOT and the maximum capacity AND the max speed that it supports. My computer for example supports 2 gig of ram max and 1 gig per slot and it supports a speed PC2-4200max. So the memory I should get is something that's close around PC2-4200 or less. finally i think i understand most of the concept
Chris,
If the Bus Speed were 133 MHz, the HP Spec calls for PC2-4200 - (2) Gigs Max of Memory.
Your Bus Speed is 100 MHz so the HP Spec calls for PC2-3200 - (2) Gigs Max of Memory.
These are the HP Specifications for (2) Different Versions (SKUs) of your machine.
There is (NO) such thing in HP Specifications (as getting close).
I do (NOT) recommend that you deviate from the HP Published Specifications.

what the heck? bus speed?.. hm.. i don't know what it is. but how do you know that my bus speed is 100 MHz?

Quote: 'The system clock is the actual speed of your FSB with out any enhancements (such as double pumping, or quad pumping) on it. The system clock is also sometimes just called the bus speed' :unquote
----------------------------
I'm sorry I (shortcut the nomenclature) just as in the above article quite often.
The Clock is 100 MHz and your Front Side Bus Speed is 400 MHz per HP specs.

Here is the (entire article) I quoted from above.

I am still unsure of what you are trying to do because I gave you the correct memory for your machine per HP Spec.
Kindest Regards,
Rick P.♦:)
i'm confused because you said i can only get PC2-3200 because my bus speed is 100MHz but my computer's bus speed is 400MHz and it actually SAYS that it supports PC2-4200.. as you posted the link
http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c00581382&dlc=en&product=1156509
Chris,
Clock is 100 MHz for Your Particular Machine. (Probably because of CeleronM 370 Processor)
Check Bios Setup for 133 MHz choice if available.

ok.. you said if the speed is 133MHz its PC2-4200MB. Then how do you explain that it says it SUPPORTS PC2-4200MB
Chris,
Please call HP Support for their official recommendation.
Kindest Regards,
Rick P.♦:)
AHHH i think i get some of what your saying. Even though it SAYS that it supports PC2-4200MB, i don't need to get that because my CPU's speed sucks. So it'll be just more of a waste of money if i get PC2-4200 because it won't use its full power since it has to slow down for the CPU? is that it? or..

How To Check Ram Mhz Windows 10
Yes my friend, since you said it first, (in my personal opinion); Celeron CPUs are inferior - (Suck) - for numerous technical reasons. You interpreted my previous postings correctly.
Kindest Regards,
Rick P.♦:)
dude. celeron does suck. no joke.. it's because it's so old and stuff.. anyway. you should've said that you were talking about the Bus speed FOR the CPU. I got confused because i thought you were talking about the memory's bus speed. When i tried to look for the Bus speed for the CPU from the HP website. it's not there right? it only tells you the bus speed for the MEMORY. hmm BUT i used the CPU-Z system to check it out and stuff and I found that it says the bus speed for the CPU is 99.9MHz. which is basically 100. So I believed you. You see.. i can't believe stuff unless i see it for my self. you know?
Chris,
Dude, you made my day because you proved me correct plus you learned something while doing it !!!!
Works just like in school.
You do your homework FIRST, and then the next day ask a teacher questions about the homework problems which you might have had trouble with. :) :)
Kindest Regards,
Rick P.♦:)
Wait.. as I think about it.. does the CPU's bus speed really matter? If you think about it.. isn't it the Front Side Bus that matters? because CPU's bus takes other roads. I'm using 'roads' because i read the article that you gave me. Isn't the Front Side Bus for the road for the Memories bus? I'm confused now.. as i think about it.. does the CPU bus speed matter? i'm confused..
