Can You Use RAM With Different Timings?

Can you use all 4 RAM slots?

A common misconception about RAM is that you can put any RAM into any slot.

You can do that, but it won’t work, or it will work ineffectively.

If you have four RAM slots, always buy matched pairs of RAM (two sticks from the same company, same speed, and same capacity) for the best results..

Can I use 1333mhz and 1600MHz RAM together?

Yes, you can mix 1333 and 1600 MHz RAM sticks, however the system will downclock all RAM to the speed of the slowest stick. For best performance, try and buy RAM that is the same speed or faster.

Can I mix 1.5 V and 1.35 V RAM?

Yes, you can use a low voltage RAM module, rated at 1.35 V or 1.25V with a normal RAM module rated at 1.5 V. The Low voltage RAMs (DDR3L) are backwards compatible so they would work with most of the CPU and Motherboard combinations. … Will a laptop start without RAM?

Can I add 8gb RAM to 4gb laptop?

If you want to add more RAM than that, say, by adding an 8GB module to your 4GB module, it’ll work but the performance of a portion of the 8GB module will be lower. In the end that extra RAM probably won’t be enough to matter (which you can read more about below.)

What are good RAM timings?

Your millage may vary depending on the word burst allowance being used in a transfer, so these are just basic timing numbers. CL 8/9 is pretty good timing for 1600 sticks, a bit faster than 11. And a good read on what DDR4 is all about with respect to DDR3 and future DRAM configurations…

Can you change RAM speed without BIOS?

You have to enable XMP profile in BIOS to get 1600mhz running (which I doubt an older board can even do). No worries, I had just read in a few places that the RAM doesnt always default properly and you can change the settings manually.

Is it OK to mix and match RAM?

As long as the types of Ram you mix are the same FORM FACTOR (DDR2, DDR3, etc) and voltage, you can use them together. They can be different speeds, and made by different manufacturers. … Different brands of Ram are fine to use together.

Can you change RAM timings?

After you’re in BIOS or UEFI, look for an XMP button. XMP stands for Extreme Memory Profile and is an Intel technology that allows you to select a profile for your memory to change its timings.

Can I use 4gb and 8gb RAM together?

That’s why it’s best to use the same model in all slots. However, this doesn’t mean you can’t use different size RAM sticks together. For example, if your first stick is 4GB, you can still add a new 8GB stick. … Your RAM sticks will work together at the frequency of the lower stick, by default.

How do I optimize RAM timings?

Start off by lowering the first (tCL) and third (tRP) timing by 1. If this passes one round of Memtest86+, try lowering the second timing (tRCD) by 1 and running the test again. Note: If you haven’t reached your maximum RAM voltage, increasing it will usually allow you to tighten your timings even further.

Will Ram with different timings work together?

The timings and maybe even speed are different but the voltages are the same. … When this is done you will have full access to not only the RAM timings but also the voltage requirements. Since both the old and new RAM are the same voltage simply manually hard setting the RAM timings to what ever is the slowest.

Can I use RAM with different voltages?

Brands. We have established that you definitely can’t mix generations of DRAM. And it’s not optimal to mix modules with different speeds, latency, or voltage.
