___________________________________________________________________

the problem is that when i run a heavy aplication (or game) my pc starts to slow down,... i checked my memory bandwidth with SiSoftware Sandra and it gave me a 30% efficiency (wich is extremly low), i downloaded all kind of patches, updates, etc, looked for the memory timings also, using 2.5 3 3 7 atm.

any suggestion will be highly appreciated, please

Did you build your computer yourself? Do you know who manufactured the RAM? When you mention it happens with games, could it be your graphics card? Any more details on the situation could help.

I would suggest setting the RAM timings, voltage, etc to BY SPD to start with (in the BIOS). this will allow the mobo to auto configure everything for what the ram says it can do. see if that helps with the issues at all.

yes, please do list the make of your ram, etc.

also, check your temps- hopefully you have a monitor program of some sort, that can show you cpu temp. I ask this since you say it slows down when under heavy loads- P4 will start reducing its performance if it gets too hot, to avoid burning up the chip.
if you dont have a monitor program, use everest home it has a temp monitor included. list the idle temp, and the temp under loads- run the game for while, with everest running as well. when you start getting slowdowns, exit the game and check the CPU temp. post those numbers here, and we can make sure your OK.

audioboy has lots of good points..


I will add this..Hit control-alt-delete and check how many background programs your running and check your CPU usage.

Spyware can sneek up on you :tazz:

Warning 5400 : Low bandwidth efficiency (advanced). Check memory timings and settings.
Tip 2 : Double-click tip or press Enter while a tip is selected for more information about the tip.

that's what sisoft sandra tell me about my memo and its performance, as you can see is horrible, about my memo, its suppose to be kingstone but cpu-z tell me this:

Slot 1:
manufacturer: Samsung
part number: M3 68L5423FTN-CCC
serial number: 410B0566

Slot 2:
manufacturer: Samsung
part number: M3 68L5423FTN-CCC
serial number: 410D5A17

im currently running the memo at 3-3-3-6 (from bios)
i dont realy think the problem is spyware because i just format this hard disk and the problem is still there
the tempeture on the cpu is usualy 40-44C

I would still suggest putting the ram settings in the BIOS to "by spd." both for the timings, and voltage.

samsung makes the actual chips that go on many ram sticks, that is likely what sandra is reporting to you.

sounds like it would be good to test that ram out some. use memtest 386. loads onto a floppy, and is a bootable disk. run the test with one stick at a time, for at least an hour each. I prefer longer test times (it will run the same series over and over) sometimes as well. if you start seeing errors, try the other stick, see if you get the same errors.
report the findings back, it should help tell us if you have some bad ram.
