PC100 + PC133 = hhmmm 1

Ok.. Stupid question that I should know..

I have PC133 in my computer right now.. I have a whole arse load of PC100 sitting right here beside beggin to be used.. Can I combine the two of them in the same computer or is that a bad idea?

Go to crucial dot com or another major supplier and use their "configurator" on the motherboard mfr. make and model and see what they say will work.
They guarantee it!

Most likely they will work together, but remember that the lowest frequency is always used. So in your case, the PC133 will go down to 100 mhz. ~Apex1x

Ok cool.. But If I'm going to have like 500 some meg it really shouldn't matter right? Anyhow.. all mod's are kingston.. so i'm thinking they'll work.. "tis better to remain silent and be thought of as a fool..

use the memory config. LOL

Well, there is perceived speed and actual speed...

With more memory, you can store more applications in memory but they will be loaded slightly slower than if you had it running at 133 mhz.
However, with more capacity, you wont need as many requests and therefore things will appear to load faster.
So what you'd be experiencing is perceived speed.

Its kind of like the difference between bandwidth and latency with internet connections.

snootalope,

Just be careful when mixing the two types. If your motherboard's memory bus runs at 133MHz, PC100 won't work at all unless the motherboard can slow the bus speed. In most cases, that won't be possible.

Usually, it's alright the other way around. If you had a 100MHz memory bus, PC133 usually works fine because it's backward compatible.

Also, there can be a significant difference in some benchmarks between 100MHz and 133MHz bus speeds. Don't use PC100 unless you're absolutely positive that your motherboard's memory bus can't run at 133MHz.

When using 133 Ram on a 100 Motherboard you may find that a 256 will only be recognised as a 128. Or not at all as has happened to me.
