if you use 3 sticks of mem just try to run Sandra...para mahibal an hehehehe...

im looking for (see page 8. ) sa amd...

in P4 manuals, it clearly says single mode for 3 rams.

im trying to look for AMD version of this. basig naa sa inyung manual?

i believe you have 2 channels with 4 slots
the 3chips/dual channel mode is supported mostly on boards with 2 channels with 3 slots. that means the 2nd channel is composed of 2 slots. if you have an even number of slots, an odd-numbered chip config will not work in dual channel mode. i believe some intel chipsets also support this 3slot/dual mode config

BTW, the system will either work in dual channel mode or single channel. it cant be both like channel one works single and channel two.. dual.

how about the command rate?
1t or 2t?

if your going to have 2x256 on channel 1 and 1x512 on channel
would it be 1t command rate or 2t?

if ur ram can handle 1T, then 1T tanan

great! i'll be getting another stick then.

1t... whosh! lupad nana

Dual Channel requires at least two modules for operation. It is recommended that the modules you use be of the same size, speed, arrangement etc. Dual Channel is optional on the original nforce2 motherboards and nforce2 ultra400. You can choose to run in single channel mode on these motherboards. (Nforce2 400 boards are singe-channel only).

Most dual channel capable nforce2 motherboards come with three slots. On these motherboards the first memory controller controls only the first slot (or the slot by itself), while the second memory controller controls the last two slots (which are usually closer together). Name them slots 1, 2 & 3 respectively. To implement Dual Channel, it is necessary to occupy the slot 1 (channel 0) and either one of the two slots that are closer together, slots 2 or 3 (channel 1) The entire config would be running in 128bit mode.

You can use three modules in Dual Channel Mode, by filling the third unoccupied slot. With three sticks, slots 1 remains as channel 0 while slot 2&3 become channel 1. To maintain 128-bit mode, with all three slots filled, each channel must have an equal amount of memory. For example, slots 1 should be filled with a 512Mb module, while slots 2 & 3 are populated 256Mb modules. If you were to use three modules of the same size, then only first two modules would be running in 128bit Dual Channel Mode. Example, using 3x 256Mb modules will have the first 512Mb running in 128bit Dual Channel mode, while the remaining 256Mb will be in 64-bit Single Channel mode.

Intel dual-channel systems are different. The have either two or four slots, and to run dual channel mode must have either one or two pairs of (hopefully) matching modules. Running three modules on a P4 system will force it to run in single channel mode, and is therefore to be avoided.

Consult your motherboard manual for instruction on exactly which slots exactly to use.

dual channel involves pairing of memory so you can have 2 X 512MB or 4 X 512MB....it can never be 3.....

To be sure you should do a memory bandwidth test which is found is SiSoft.

gahi-a utok uy!!! kapila na ingnan pwede lagi na 3!!! most probably you're not an AMD user
