i have intel 946GZIS.. and 512 mb DDR2 667mhz... i wanna knw if i can do dual channeling on my mobo..??cos i have read tat dual channeling requires 4 Ram slots... but i have only 2 slots on my board...but inside my memory configurations in my bios its listed lik dis (approx) DIMM 0 Slot A - 512 mb Slot B - none DIMM 1 Slot A - none Slot B - none When i have only 2 slots on my mobo how can it show 4 slots inside the bios memory configurations???and how to dual channel in this motherboard??
I'm not sure where you read that dual-channel memory requires 4 slots, but that is incorrect. Chipsets that have a dual-channel memory feature have two memory channels, which typically allow for 2- or 4-memory slot configurations. To enable dual-channel memory you must have 2 sticks of equal size. A stick must be installed in each channel so that both channels are identical. From the looks of it, the BIOS is listing the banks as slots. A bank, as far as DIMM slots are concerned, refer to the sides of the DIMM PCB (Printed Circuit Board) that can have memory chips. There's only two banks per DIMM PCB and slot. The stick you have in there right now appears to be single-sided. To enable dual-channel, you just need to add a second stick of 512MB of DDR2. For best results, you'll want to match it to the stick you have in there now with a second stick of DDR2-667.
Thanks a lot for ur reply.. i understood now.. as i have mentioned before i have a 512mb ddr2 667 mhz ram.. can i get another 512mb same make ram and add with my previous to make it 2x512mb dual channel or shall i get 1 gb ddr2 667mhz ram to make it 1x512mb and 1x1gb totally(1.5gb) single chennel ram??? which wud perform better?? can u pls explain??
That would depend on what you're doing. Lots of gaming and video editing would be better served with more RAM than dual-channel. If you simply e-mail, websurf, and do office apps, adding more RAM won't do much for performance past 512MB under WinXP, so after 1GB, you'd just be throwing money away. Games and video editing love RAM, regardless of dual or single-channel configuration. You'd get more improvement by allowing for more room here, because if they don't get enough RAM to run with, they'll just grab part of the pagefile, which is simply a certain amount of space set aside to act like RAM. RAM is much faster than a hard drive, so having to access is not desirable.
thanks again ... one more doubt... i was previously using intel D102 with ddr2 533mhz ram with dual core 2.8ghz processor..a couple of days ago i bought a new intel 946GZIS and core2duo 1.8ghz E4300,ddr2 512mb 667mhz ram and new SMPS, 160gb SATA, LITE-On 20x DVD writer and an old cd rom...after i installed windows xp, sometimes when i open some applicatons and work or if i see some movies suddenly my systm gets restarted...after my windows starts again i get a msg tat "windows has recovered frm a serious error" n bla bla bla..i tried changing the ram,but still i had the problem.. then i tried changin the smps still i faced the same problem.. then i formatted my system and reinstalled windows xp yet again i face the same problem.. pls help me wat cud b the reason.. i chked the cpu cooler also and i even chked the temperature... its optimum..
