Is 667 Mhz RAM good?

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.

What is RAM FSB speed?

Stands for “frontside bus.” The FSB connects the computer’s processor to the system memory (RAM) and other components on the motherboard. Most computers’ processors run faster than their system buses, so the FSB speed is typically a ratio of the processor speed.

Which RAM has higher speed?

Memory Speed The speed is the clock rate at which the memory communicates with the CPU over the front side bus. Higher FSB and memory speeds result in better performance. The highest-performing DDR3 memory available to consumers currently can transfer over 12GB of data per second at its peak rate.

Can I use 800MHz RAM instead of 667?

Yes, in general, you can use memory of any speed as long as it fits.

Can I use DDR2 667 with DDR2 800?

Normally they should work without an issue. BIOS automatically sets the speed to the slowest one. So the DDR2 800 stick should be running at DDR2 667.

How do I find the FSB of RAM?

The easiest way if you have Windows 10 is to right-click on the taskbar and choose Task Manager from the menu. If it’s in compact mode, click More details, then click on the Performance tab. Click on Memory and you’ll see how much your computer has in the top-right corner.

What determines FSB speed?

Memory. Setting an FSB speed is related directly to the speed grade of memory a system must use. The memory bus connects the northbridge and RAM, just as the front-side bus connects the CPU and northbridge. Often, these two buses must operate at the same frequency.

How fast should my RAM be?

For us 3,200MHz memory with the common timings of 16-18-18 should be considered the baseline for all but budget systems. The only reason a gamer should go with very fast 4,000MHz+ RAM is if you’re running a high spec Intel system and you’re into competitive first person shooter games on a high refresh monitor.

Can I replace DDR2-667 and 800?

So long as you purchased PC2-6400 DDR2-800 DIMMs in an appropriate capacity, you can safely use them in place of the PC2-5300 DDR2-667 units specified for use with your particular machine. The inverse is not true: you could not use slower memory modules in a later, faster machine.
