hello

Yesterday I went to buy more memory to my computer, the seller told me that I need a memory with CL match what exists on the computer, otherwise I will get blue screens.

Is this true? In another store I was they not even mentioned it.

i have  4gb ocz repear kit ddr2 800mhz

thanks.

Complete and utter Rubbish... As long as they are DDR2 and not diffrent like DDR, and DDR2 or DDR2 and DDR3 you will be fine.. the main thing u must do though is make sure they run at the same speed e.g 800mhz for all of them and not 800mhz and 1333mhz must be one set speed otherwise the faster speed will downspeed to the 800mhz and u will get errors.. as long as they are the same TYPE (DDR,DDR2 or DDR2) and are the same speed.. you will have NO problems.

Best of luck.

Blue screens can happen if the motherboard reads one SPD on a memory module and tries to use it to run all the memory modules at that rating and the memory isn't up to that spec.  You can get around that by manually setting the timings to the lowest common denominator; this will guarantee that none of the memory is being run out of spec.

The CAS latency spec has nothing to do with the total bandwidth spec.
there is no point in him playing around with the bios settings, just get memory which are the same speed like i siad. simple and no messing about .

Why are you acting like the ultimate authority on memory?  You obviously gave wrong information about CAS latency, which is what CL means.  He can do what he wants with the info provided.

hello guys

thanks for your replys

Callandor how can i do what i want with the info provided , i have no knowledge to decide that.

is there any reference you can post to the reply above ?

What are the timings on your current OCZ Reaper RAM, and what does your BIOS say they are set to?  If you don't overclock your memory, you can get by with RAM that has slower timings, but you may need to set the timings manually.  Otherwise, you can get memory with the same timings, but it may cost more.

Patriot makes very good memory, and that memory you selected is a good choice.  The timings are the same as what you have now, so there should be no problem using them together, but if you are populating all 4 slots, there is a small chance that the additional load may cause instability.  In general, two RAM modules are the safe way to go, though 4 usually works.  I have a similar motherboard, a GA-EP45-UD3P, with an E8400 cpu and like Gigabyte motherboards for their quality construction and features.

just to know for the future most cases if i buy diffrent CL it will work ? include the bios method
you wrote above ?

If the CL is quicker, it will work.  If the CL is different but faster than the standard configuration for your cpu, it will work.  If the CL is different but slower than the standard configuration, it may not work.  Using the BIOS method will work all the time if it is equal to or slower than the standard configuration.
