I got this from pc wizard 2008.

Format : Regular UDIMM (133.35 x 3)
Size : 1024 MB (2 ranks, 4 banks)
Module Buffered : No
Module Registered : No
Module SLi Ready (EPP) : No
Width : 64-bit
Error Correction Capability : No
Max. Burst Length : 8

Does this mean My ram is runing slow or had the wrong setting?

Also it seems my system is runing very hot.

:( I need to maybe get a custom fan or water cooling? coz I leave my computer on 24/7 most of the time.

this is why computer got problems due to heats yeah you should :p
if you can't afford getting your aircon for 24/7 :p

Orly? my laptop gpu nvidea not working shows 64 (well dont remember what value is??? just shows temp gpu) normaly, and when working shows 68 and if the weather is hot ,it can go to 71.

Dunno if thats suposed to be bad but since i bought it always showed around 62 or 64 when just turned on, and to think i bought the best support with best cooler for it :P was all talk probably too dunno. (laptop is now 1 year +6 months old)

Nope it's running perfectly fine as you will only see half of what your RAM is capable of as what you see is the memory clock and not the I/O Bus clock which makes up the remaining 400Mhz.

here's a little information for you to digest (http://en.wikipedia.org/wiki/DDR_SDRAM)

If it's on 24/7 make sure you get a custom fan or water cooling system.

ddr2-800 is meant to run at 400mhz.
there's a reason why it's called ddr.
heat doesn't magically lower your
ram clock rates

The highest temp you have listed is 68 on your video thats equal to 154F. Thats hot but most GPUS and CPUS can run safely as high as 170 with no harm. That would be 76C for you metric people. If your that concerned you can use larger or faster fans or maybe a larger heat sink and fan. The only time you really need water cooling is if you have over clocked and you are running very near the temp limit of the device. Go to you GPU and CPU manufacturers website and look up the technical specs for the chip It will usually show the safer operating temperature for the device.

As for the RAM 400 is the correct speed for DDR2 800. DDR means double data rate so they cheat sort of on the number meaning your bus is 0nly 400 but you get double the data flipped on each cycle so effectively your RAM is cycling data at 800 on a 400 bus. Your RAM speed indicated is normal.

I see. thx for the info. but water cooling is quite expansive. So I will just stick with this for now. :( Hope it doesn't overheat.

If need be, open the sides of your case,
and keep it away from a wall. That'll drop
it at least 10-15 degrees.
