CL - Cas Latency

Should be the lower, the better...

like CL2 better than CL3..

Supposedly, the ram capacity should detect your ram as 1024 instead 1023.

for notebook, at the moment there are only mathc pair value ram available. No performance ram yet.

how to check whether the processor can support ddr 800?

actually not check processor.its check your own motherboard manual.they should include all the details.

depend on the mobo chip set..
if for intel...
965 is the only 1 in market able to support ddr2 800

check you mobo manual. For instance, Asus stated on its manual to use corsair ram for stability.

DDR800 Mhz is basically will able to work with 667Mhz DDR2 RAM slot. But by default, it will run at 667Mhz instead of ram default frequency of DDR800Mhz.

Noted: Check and do research on forums to identify which model have good compatibility and stability with your motherboard.

actually need to check both
AMD platform has memory controller built on CPU , not on motherboard .

only one ? are you sure 975 cannot ke ?

Many Intel mobo ccan support DDR2 800Mhz or even higher frequency. But withput having OC, the default setting will detect the ram as what stated in manual.

sure..975 only run 667...

my RAM is Corsair TWIN2X1024A-6400 which is DDR2 in pair 800Mhz. i have checked the CPU-Z, it stats tat my ram frequency is 400Mhz. Is it on the right speed?

Yes it is. By default it is stated like that as the 400/0.5 Mhz.

How bout the latency it is stated 5-5-5-12.
But wad i found is 5-5-5-18 in CPU-Z

Yea agree. I just bought TeamGroup's Value Ram. Its a Micron D9DCN Chipset. This rams can go up to 1020MHZ round 510DDR2. Not too bad for a budget Value Rams.

It should be fine. My DDR400 is showing as 200Mhz as well. I think it got something to do with DDR which means * 2 for the Mhz..

You can manually set to to its default factory setup to 5-5-5-12. If not stable, try to set to default Voltage. If im not mistaken, corsair model that you mentioned is well stable at 1.9V with 5-5-5-12 2T. Same like mine in my system.

Go to bios to change to this setting.

Yea i agree. My Corsair ram previously stated at everywhere is 2.5-3-3-6 as well but when i plug it into my system, it ran at 3-3-3-8. However, you could just manually change the timing at the bios without the need to change any other thing and it will still run smoothly as well...

Actually if i don change it back what will happen?

Nothing will happen.Actually those timing are going to affect the speed of the system but to be honest, whether you notice them or not is going to be different.I personally tested the Corsair Ram (running at 3-3-3-8) and OCZ ram (running at 2-2-2-5) with both of them running at different timing and i couldnt feel any different in it.Other people might but i certainly dont...

Anyway, anyone knows a way to check the temperature of my ram?I just bought the Dominator Airflow Fan and would like to see how much it helps to cool my rams though..

Normally by normal use, it would be Okay to run at default timing detected by your motherboard. Therefore, if you want to achieve what you deserve on having performance ram, you should set the timing to its lower timing. Of cos overclocking will enhance more performance to its, but frankly speaking there is slight faster in the timing is lower.

You will noticed this when comparing two PC running on identical setting but with different ram model and timing.

Hi,
Got noob question here
I have 2x512 kingston DDR2 667,
wanna ask, how to determine whether this is what chipset (hynix)?
See at the RAM itself or the box label?
Cos i'm planning to upgrade my RAM.
Thanks
