i am new to this forum
i want to build my first desktop
cpu: amd opteron 165
mobo: Dfi Ultra-D
Memory: OCZ 2GB (2 x 1GB) 184-Pin DDR SDRAM Dual Channel - Retail
http://www.newegg.com/Product/Product.asp?Item=N82E16820227210

my question is i want to oc my opteron to 2600 Mhz, from what i just learned that have to be 288.889 x 9 = 2600 (not sure if it's right formula or not ><)
is it possible to oc the memory to 288.889 fsb?
or i need buy some other memory?
btw i see there are lots type ocz 3200 memories listed on this forum.
which one is mine?? how do i check what type memory i got?

thanks for the help

well, close but not w/ the fractions. CPU memory controller will adjust to nearest even ratio. If you run mem/CPU @ 1:1 ratio, you will only be able to overclock CPU as high as memory can support it- DDR500 (250mhz double data to make it to 500 MHz) CPU will be overclocked to 250 MHz. sometimes memory modules have a little head room and could go higher than rated. for example DDR500 could go little higher to lets say DDR550. all depends what memory brand and how good they are.
many also use memory dividers to overclock CPU higher than memory. for example: if you use 166/333 memory speed/divider in bios, it means, it is a 5/6 divider(166/200=.83=5/6) so the result will be like this:
CPU @ 280mhz, ram will be @ 280*5/6=233.33, rounded to 233mhz memory speed, which means DDR466(2x233=466double data rate=DDR466).
so w/ a ram rated @ DDR500, you could overclock CPU up to: 500/2=250*6/5=300mhz CPU. bingo. and 300*9=2.7ghz :santa: holy mo.
Now you ought to remember it is not that easy. you got to play w/ vcore, vdimm, NB/SB Hypertransport speed, and memory timing to get it all right.
your winxp and program files may have to be corrupted and reinstalled 10 to 20 times, before everything all right, and you feeling as contempt as a lion hugging a lamb.

Good luck :)

what i can say. thank you so much!!!
now i got the idea how to do it. will try it once i got all parts.
and will post results here.
