Solved 800mhz ram in 1066 slots? Tags: Memory RAM Product Last response: November 5, 2010 2:01 AM in Memory Share opexx November 4, 2010 9:01:30 AM I have a mobo that says memory standard is 1066Mhz, but my current 8gb of ddr2 is 800mhz.. Is this still usable, even if i have to overclock the memory speed in bios, or is this totally useless? More about : 800mhz ram 1066 slots Emperus a b } Memory November 4, 2010 9:22:20 AM Please mention the make and model of your motherboard.. 1066 MHz may be the max memory speed supported by the motherboard in which case, your 800 MHz modules will be very much supported.. opexx November 4, 2010 10:12:19 AM its an nvidia nforce 750i SLI FTW http://www.newegg.com/Product/Product.aspx?Item=N82E16813188026 Related resources DDR2 RAM : Better performance with 5GB @ 800MHz or 4GB @ 1066 MHz? - Forum DDR2 Ram 800Mhz and DDR2 1066 Mhz in same Mobo...? - Forum 1066 mhz ram running at 800mhz ? - Forum DDR2 1066 Mhz or 800Mhz - Forum Is 2gb ddr2 running at 1066 mhz in dual mode better than 3gb at 800mhz - Forum Can't find your answer ? Ask ! Get the answer jsc a b } Memory November 4, 2010 12:06:22 PM That's basically the max supported. But it won't matter that much. I don't think, regardless of advertising, that you can make the whole system run that fast. It says that FSB is 1333/1066 MHz. That's FSB freqs of 333 and 266 MHz. That corresponds to memory speeds of DDR2-667 and -533. And Core2 systems just do not benefit from overclocking the memory. Then there is very little true DDR2-1066 RAM. Most of it is DDR2-800 RAM that has been tested to run at the higher speed by increasing the voltage and relaxing the memory timing. Save your money and buy good DDR2-800 RAM. opexx November 4, 2010 8:27:37 PM Well I have 8GB of corsair [XMS] ddr2-800 already, I want to make sure I can use that same ram on that mobo. Best solution Emperus a b } Memory November 5, 2010 1:20:32 AM Yes you can.. The motherboard supports a max memory quantity of 8GB at the best rated speed of 1066 MHz.. So yours is well within the specs.. opexx November 5, 2010 2:01:12 AM sweet! thanks for the help opexx November 5, 2010 2:01:29 AM Best answer selected by opexx. Can't find your answer ? Ask !
