Hi.
I would like to ask you..
I have a PC (Pentium 4 at 3Ghz HT, Asus MOBO) with 4 modules of memory at 400Mhz.
The two of them (2x1GB)are Kigston Hypex with faster clockings than the other two modules which they are from Transcent (2x512MB)
With these two modules that have not the same clockings, will it be right to rip off the two slower modules??
I heard that when we have installed memory modules in a PC that have not the same timmings, it's not so good..
Is it right or wrong ?
Thanks

Thank you very much.
It was very helpful.
So 2GB of Kingston Hypex DDR Memory is faster than 3GB of the same memory modules mixed with older.Right?

If the modules run at the same mhz and the only difference is the timimg specs x-x-x-x, the difference is so tiny you probably wouldn't notice it. Milliseconds at the most, and the CAS ratings only apply when the ram is first accessed - if it continues to be accessed, which is frequently the case, there is no difference in the performance of the ram that has the same ratings otherwise.
Also, the mboard chipset and bios must support the faster timings - if it doesn't the mboard bios will default to whatever it's max settings are if the modules exceed those settings.

And my question remains.. :)
3GB of different clocks memory modules? (faster and slower) ? OR 2GB of fast memory modules?
1. 2x1GB Kingston Hypex (fast clocking) WITH 2x512MB (slower clockings)?
..or
2.2x1GB Kingston Hypex (fast clocking) ??
Thank you again.And sorry being a pain in the ass.. :P

As I said, if all the ram runs at the same mhz, the difference is unlikely to even be noticable. You would be better off with more ram of mixed timings. On the other hand, unless you are stressing your system to the max, you don't actually need 3gb and are unlikely to notice the difference between 2 and 3gb of ram anyway.

If you motherboard supports memory timing adjustments, all you need to do is change them. You haven't really told us anything about the RAM other than the brand name though. How about telling us exactly what you have (PC3200?) & what the default timings are for each pair.
When you install RAM with different timings, the BIOS will identify the different timings & run ALL sticks at the "weakest" setting. For example, if your Transcent has timings of 3-4-4-8 & your Kingston has timings of 2.5-3-3-7, the BIOS will run ALL the RAM at 3-4-4-8. However, if you board supports manual adjustment of the timings, all you'd need to do is them to 2.5-3-3-7. Almost all CAS-3 RAM will run at CAS-2.5.
But if your Kingston has extremely tight timings such as 2-2-2-6, there's no way you'll get RAM with 3-4-4-8 to right at those settings. 2.5-3-3-7 would have to be the compromise.
