    Default trying to get the ram up to right speed?

    i hope someone can help me..ive read through some of the posts but i cant figure out what to do...i am pretty new to this and im stuck... i just bought the gigabyte ga-ep45t-ds3r/ds3 motherboard and 2x2gig (patriot memory) PDC34G1600ELK (DDR3 1600MHz 9-9-9-24 1.8v) with the board being 1600 fsb and ddr3 can be overclocked to 1900...i am only getting the memory at 1333 and windows reports the ram at 3.25GB. i think i heard that since im using windows xp pro sp2 i can only get 3.3 out of my 4 Gb of memory...is that true? the processor is at 3.0GHz.. so what i wanna know is how much can i overclock the the 3.0GHZ to (what settings can i do before it becomes unstable),am i only gonna be limited to 3.25GB from the ram instead of the full 4GB, and what do i need to set the bios to so i can run the ram at the number that its supposed to be(1600) and not what its at right now(1333)... hope someone can help..thanks in advance...ROB...sorry..i forgot to add i used memset3.6 just to see whats up...this is what it says...my memory is ddr2 666.8MHz fsb/dram 1:2. I changed the timing from 7-7-7-20 to 9-9-9-24(those are the numbers on the sticker)... i dont understand how thats possible that it says the ram is ddr2 when its supposed to be ddr3.

    Yes, Windows 32bit only sees around 3.25GB of Ram - it's a 32bit OS limitation. You can overcome it by using a 64bit OS.

    yes i know.. thank you for that link(already looked at it) VorLonUK..not to be rude...but thats all gibberish to me.. i dont have that much of an understanding...i dont wanna just start putting random numbers in. maybe ill just call tech support on monday if no one can help me figure it out. thanks

    Your maximum Memory multiplier is 4x, which means 333 x 4 = 1333Mhz
    To run your RAM at the advertised 1600Mhz, which may or may not work on your board, you need to run the CPU Host frequency at 400Mhz, ie 400 x 4 = 1600Mhz.

    Using my telepathic powers, i'm assuming you have an E8400 at 3Ghz?, if you are then you have a 333/1333 FSB CPU which has a CPU Multiplier of 9X, ie 333Mhz x 9 = 3000Mhz aka 3.0Ghz.

    What that means is if you set the CPU Host frequency to 400Mhz and your Ram Multiplier to one of the 4X straps, you'll get your DDR3 running at 1600Mhz and your CPU running at 400 x 9 = 3600Mhz aka 3.6Ghz. ie a CPU overclock, which may need better cooling. Are you using the Intel stock cooler? If you are it's unlikely enough for a 20% overclock.
    But to be honest i doubt very much your your DDR3 will run at 1600Mhz in your board without a lot of tweaking. There are few boards where this is easily achievable.

    i downloaded cpu-z, it was a problem with memset..is ddr3 indeed. here is a screen shot of all the info... http://img518.imageshack.us/img518/2227/cpuzfa4.jpg

    i built the computer myself..it isnt stock.. i used the high performance ultra quiet cpu cooler (CNPS9500 AT) by Zalman.

    thanks VorLonUK but i cant seem to get better than 1333..which is a bunch of BS! oh and tech support when i called was no help...Freakin worthless...so thank you and i guess next time i put together another computer a GIGABYTE motherboard is out of the question...just worthless paper weight and a waste of money, seeing as tech support wont even help...later

    That's what the board is designed to do - what more do you want?, when you make comments like this:-

    That "Gibberish" as you call it is an excellent guide to those who wish to overclock. If you don't wish to overclock then that's fine, your setup appears to be working properly.

    i didnt mean that in a bad way...maybe i used the wrong word...by gibberish i meant that i dont really understand it...i could sit there and read it 50 times and i wouldnt get it..thats why i asked so i could get an answer from a person... im sorry if i offended you.. but i wrote this right after i got done with tech support... half an hour on the phone waiting and no help...i was kinda peaved. if i would of know that ill i could get was 1333 with ddr3 at least thats what its running stable at..i would of just saved some money and bought something cheaper... i had it running a little higher without shuting me down...but my programs were acting funny..they'd freeze up.
