Can I use 800mhz RAM instead of 667?

Yes, you will benefit from 4gb. A 64bit OS (with 64bit apps)would make better use of that 4gigs. Its not really a good idea to mix different speed RAM, but it might just work for you. i’m running different speeds of RAM in 3 stick and never gave a problem.

Why is my RAM speed 667?

The memory is running at 667 MHz, which equals 1333 MT/s because of the Double Data Rate that gives DDR3 its name. Your kit is rated to run at up to 1866 MT/s, which is actually only 933 MHz. Most kits default to 1333 MT/s = 667 MHz, so you need to go into BIOS/UEFI and set it to the faster speed.

Can I use 1066 and 1333 RAM together?

You can mix RAM of both speeds (1066/1333). The system will automatically use the slower speed, but there is no risk of system crashes.

Is 1066 Mhz RAM good?

Polypheme. In modern editing 1066 is a bit slow. You’ll want to go for something well balanced such as 1866MHz RAM, and buy the same model for all sticks in the future due to the voltage irregularities and recognition issues different modules create.

What is the difference between 667MHz and 800MHz RAM?

Distinguished. It’s more or less a capability rating. The 800MHz RAM is rated to provide data to the CPU faster than the 667MHz. However they can both operate at 667MHz or lower or even higher, though if its higher than the RAM is rated for its considered to be overclocked.

What does pc6400 mean?

The “6400” refers to the module’s bandwidth (the maximum amount of data it can transfer each second), which is 6400MB/s, or 6.4GB/s. DDR2 PC2-8000 (commonly referred to as DDR2-1000) memory is DDR2 providing a 1,000MT/s data transfer rate).

Is 667 Mhz ram good for gaming?

The short answer is yes. The ram has a delay whenever the CPU need to grab some numbers to crunch. Faster ram will make the numbers get crunched faster. If 667 Mhz is okay for you right now, I wouldn’t upgrade.

Can I use 1600MHz ram in 1333MHz motherboard?

The compatibility of the ram depends more on your motherboard than your cpu. If your motherboard supports the 1600mHz, then it is likely that the g3258 will also. However, the cpu spec sheet says that it only supports up to 1333mHz, so if you use 1600mHz sticks it may downclock them to 1333mHz.

How do you know if my RAM is 1333 or 1600?

Clearly, you can see my ram is 1600 mhz from the name. BUT standard setting for all DDR3 sticks is 1333 which is JDEC standard. This is the default setting that most motherboards are set to as long as your Ram can atleast support 1333mhz. You’d need to overclock your bios to get 1600 mhz.

Why does my RAM say 1066?

That’s just how they work. FSB speed to match the CPU. you won’t get the full speed unless you overclock or enable Intel Extreme Memory Profile (XMP) in the bios/UEFI.

Does all RAM have XMP?

All high-performance RAM uses XMP profiles, because they all run above standard DDR industry specifications. If you don’t enable XMP, they will run at your system’s standard specifications that are dependent on the CPU you have. That is to say, you won’t take advantage of the higher clock speeds that your RAM may have.

What is the fastest DDR2 RAM available?

Corsair seems determined to hold the record for the highest memory speed in production memory. We recently reviewed the highest speed memory available at the time in Corsair Dominator DDR2-1111 (PC2-8888).

Why is my RAM running at 1066mhz instead of 1600?

The old ram is 1x4GB PC3 1600MHz, and the new ram is 2x4GB PC3 1600MHz, but the bios insists they are both 1066. I noticed that the bios is very old, so I downloaded and flashed the latest one; no change.

What’s the difference between PC3 8500 and DDR3 1066?

PC3-8500 and DDR3 1066 are two names for the same type of memory. 1066 describes the speed of the RAM. The base speed is 533, which the double pumping method doubles to 1066. This is not to be confused with the actual bandwidth. The 8500 refers to the data bandwidth rate, meaning it can transfer 8500 of data megabytes every second.

Why is my Inspiron 660 running at 1066mhz?

I recently upgraded the ram on my Inspiron 660s, and in the process I discovered that it is running at a much lower speed than the specs ( downloads.dell.com/…/inspiron-660s_reference guide_en-us.pdf) say it can. The old ram is 1x4GB PC3 1600MHz, and the new ram is 2x4GB PC3 1600MHz, but the bios insists they are both 1066.
