2GB 1T or 3GB 2T??? Need Advise.

[KrEaToR]

Hi guys i got a question. At the moment i have got 2GB of memory, but i also have another 1GB sitting in the cupboard. I want the put that in my computer and make 3GB but if i do that i use up all my slots and therefore go down to 2T. So my question is this, is it worth having the 3GB running at 2T or 2 GB at 1T?

Does having that extra 1GB out weight the cost of having to run at 2T?

Thanks. Andy.

I would have thought that nothing would use the extra 1GB, so there isn't any point - however, I'm perfectly happy on !GB, so perhaps I'm not the best person to answer your question!

It helps if you tell us what you'll be using your system for

What does 1T and 2T mean?
I presume you're talking about the clock speeds (i.e. standard DDR speed with one block of memory, and then Dual speeds for two identical?)

2T = ~5% real world performance loss... I have to run my corsair at that but that's only due to a ****ty bios

and 1T?
~2.5% performance loss.

No, 2t is a 5% performance loss on 1T.. its like cas latency type thingy.. its all the rage these days :-\

Could someone write an 'essay' on this topic as I am still confused......

Command Per Clock is also called Command Rate.

"This BIOS feature allows you to select the delay between the assertion of the Chip Select signal till the time the memory controller starts sending commands to the memory bank. The lower the value, the sooner the memory controller can send commands out to the activated memory bank. When this feature is enabled, the memory controller will only insert a command delay of one clock cycle or 1T. When this feature is disabled, the memory controller will insert a command delay of two clock cycles or 2T.

If the SDRAM command delay is too long, it can reduce performance by unnecessarily preventing the memory controller from issuing the commands sooner. However, if the SDRAM command delay is too short, the memory controller may not be able to translate the addresses in time and the "bad commands" that result will cause data loss and corruption. It is recommended that you try enabling SDRAM 1T Command for better memory performance. But if you face stability issues, disable this BIOS feature."
