When purchasing a memory upgrade for your system, compatibility is the most important factor. In order for memory to work on your system, it must be compatible with your motherboard. Before upgrading your memory, consult our time-tested compatibility tips below, and use our award-winning compatibility tools to find the right memory for your system. The voltage in RAM ranges anywhere between 1.2v to 1.5v generally.The default voltage for DDR4 is 1.2v and for DDR3 it is 1.5v. Another variant that should also be kept in mind is DD3L which has a default RAM voltage of 1.35v. Also, some enthusias. I don't know what voltage they're at, could the board is fixed at 1.35V for the RAM, or fixed at 1.5V, or can detect the what the RAM needs, and sets it appropriately. I'm not sure what speed the Samsung RAM was operating at, but I think it was also 1333MHz, and the RAM was being down-clocked automatically to that speed. I have been playing with my memory frequency from 2066 up to 2933 and I am wondering how to check whether the voltage rises with the frequency. The problem is - SPD only has information about 2066 with 1.2V and 3200 (XMP) with 1.35V. So is there a way to find out what voltage is used by my.
Question: How can I check memory voltages in WindowsXP? I used to be able to check them with my old motherboard using Everest Home Edition. However, with this motherboard, for some reason Everest only shows CPU voltage and not RAM voltage.
Background: I just upgraded to a PCI-Express motherboard, the Asus A8N-E. With my old motherboard, which I loved, I got pretty good overclocks on my CPU/Memory. Now, with overclocks even less than I had before with everything the same except the motherboard, I'm getting a some instability.
I felt the memory to see how hot it was getting and noticed that it was not warm at all! In my BIOS I have the memory set to 2.75V. In my old motherboard, the RAM at this voltage was very warm (almost hot) to the touch. How can I check to make sure my motherboard is actually giving my RAM the right voltage besides looking in the BIOS?
Thanks
Testing the alternator on your 1994-1998 Dodge Ram pickup, to see if it has failed (or not), can be done with a simple multimeter.
In this tutorial, I'll show you how to do it in a step-by-step fashion.
NOTE: Although you could apply the basics of this tutorial to test any alternator... you do have to check the alternator 120 amp mega-fuse in the power distribution center (located under the hood) and the illustration I'm using only apply to the 1994 to 1998 Dodge Ram pick-ups.

Symptoms Of A Bad Alternator
In a nutshell, your Dodge Ram pick-up's alternator has two very important jobs to do:
- Charge the battery, as the engine runs, so that you crank and start your Dodge Ram pick-up the next time you need to.
- Provide electrical current to all of the accessories while the engine runs. These accessories include:
- Headlights.
- Radio.
- Wipers.
- Blower motor (for A/C or heater).
So, when the alternator fails, you'll notice one or several of the following symptoms:
- The charge light (also known as the battery light) will be shining nice and bright on your pick-up's instrument cluster.
- Whenever you turn on the headlights (night driving), they glow very dim.
- The engine won't crank. It will only crank and start if you jump start your pick-up.
- The only way the engine cranks and starts is if you charge the battery.
- The engine stalls and won't crank (unless you jump-start it).
TEST 1: Battery Voltage Test With Engine Running
This first test will confirm that the alternator is either not charging the battery or that it is charging it.
What you'll do is measure the battery's voltage with your Dodge Ram pick-up's engine running.
If your multimeter registers 12.5 Volts (or less), then the alternator is not working and thus not charging the battery.
Now, if your multimeter registers 13.5 to 14.7 Volts with the engine running, then the alternator is working and thus charging the battery.
NOTE: You'll need to make sure that the battery has enough of a charge to keep your Dodge Ram pick-up running for at least 5 minutes to do this test. If the battery is completely dead, charge it up enough so that it can crank and start the engine.
How To Check Ram Voltage
These are the test steps:
- 1
Crank and start your Dodge pick-up and select Volts DC mode on your multimeter.
Probe the positive battery terminal with the red multimeter test lead.
With the black multimeter test lead, probe the negative battery terminal on your Dodge pick-up's battery.- 3
Your multimeter is gonna' register one of two possible readings and they are:
1.) A steady 13.5 to 14.5 Volts DC.
2.) Or 12.5 Volts that will decrease the longer the engine stays running. Put an electrical load on the alternator to further confirm that it's either charging or not charging.
You can do this by turning on every accessory possible (inside the vehicle). For example: Turn on the A/C or heater on high, turn on the windshield wipers, turn on the headlights, turn on everything and anything that uses electricity inside and outside of the vehicle.- 5
Your multimeter will show you one of two things (as you turn on all of this stuff):
1.) The multimeter will register a nice and steady 13.5 to 14.5 Volts DC no matter what gets turned on.
2.) It will register 12.5 V DC and this voltage will decrease more and more as you turn on stuff inside your Dodge vehicle.
OK, let's interpret your multimeter test results:
CASE 1: Your multimeter registered 13.5 to 14.7 Volts. This test result confirms that your Dodge Ram pick-up's alternator is OK and that it is charging the battery.
If the alternator were fried, the voltage your multimeter would have recorded would have been around 12.5 Volts that would have steadily decreased the longer the engine ran.
Now, if you're having to jump-start the pick-up to get it going, then you probably have a bad battery or a parasitic drain. A parasitic drain is tech-speak for something staying on (usually inside the car, for example: a dome-light) and draining the battery while the engine is off.
CASE 2: Your multimeter registered a voltage that steadily dropped down to 9 Volts. This is a clear indication that your Dodge pick-up's alternator IS NOT charging the battery.
How To Check My Ram Voltage
Replacing the alternator at this point usually solves around 90% of the No Charge conditions on any Dodge pick-up around the world. That's right, you could stop testing here and say: ‘The alternator is fried’ and be done but..

I suggest two more easy tests to be absolutely sure it is bad. For the first test of the two, go to: TEST 2: Checking The Continuity Of The Bat (+) Cable.
