Added More Memory (Blue Screen)

Ok here it is MEM 1G|CORSAIR CM2X1024-6400 R i added 2 of thease, to the exact same 2- 2 gig ram i already had in. got BLUE screen thought i had a bad stick took 1 out, Blue screen took that out put iother in Blue screen. took both out left orignal ram in no blue screen. maybe i cant mix 1 and 2 go sticks on this motherboard-

More about added memory blue screen
  1. Is the system stable if only the new modules are installled? According to CPU-Z, SPD tab, are the old and the new modules really the same? Having the same part number doesn't guarantee that they are identical. Did you increase memory voltage a bit to compensate for the additional load? Is the system stable if you lower the memory speed from 800 MHz to 667 MHz?
  2. Are you sure they are exactly the same? The timings voltage and speed?

    Did you set them at 1.9v or just leave it on auto?
  3. go in the bios and adjust the steppings and voltages and check compatibility with ur mobo
  4. Thanks for your replys. i went into bios couldnt find anywhere to adjust voltage on ram. i know the voltage on ram already on the board are 1.8, on the 2 2 gig sticks)
    on the 1 gig sticks its 1.9,

    1.8?
    That seems really high my ddr3 Corsair vengence runs at about 1.6 volts try turning it down below 1.65 volts and see what happens

    EDIT
    My ram runs at 1.5 volts and its set to 1600 mhz

    I presume that the default is 1.8V; therefore you need to set it to +0.100V or more, but don't exceed +0.200V.

    Please don't confuse DDR2 and DDR3 memory as they are different.

    were does he say he is running ddr2 or 3 i just presumed he was running 3

    My fault he posted his brand of memory which is ddr2 is defult memory runs at 1.9

    However he's trying to use both 1.8V and 1.9V memory and that can lead to stability issues.

    Please correct me if i am wrong the mobo by default should clock down to the lower setting so shouldnt he raise to 1.9v he will have a bit of extra juice on the mem but it can have more
    This is how it works on ddr3 atleast
  12. Even if the DIMMs were identical - which clearly they are not, they are NOT guaranteed to work together or at the advertised frequency unless they were purchased as one, tested, matched kit. This is the problem with trying to add memory... Many times it simply will not function properly when mixed.

    You are correct; that's why I wrote that it should be set it to +0.100V (1.9V) or more, but he shouldn't exceed +0.200V (2.0V). Memory voltage is increased from the 1.8V base. It's a bit confusing, but it works.

    o ok the +0.200v confused me lol ok that should be his answer than
  15. your first are 2 gig each the other are 1 gig each your board is working on dual channel
  16. Ok all thanks for you help. nice to have people willing to give me a hand. Ok i found the same ram as i already have installed. same voltage. timming. make everything,,,,, 2 more 2 gig sticks . ill install them when they get here,should i still up the voltage alittle. or leave it in default which is 1.8 volts.,

    Try them at the default voltage. If memtest86+ (perform at least one complete pass - more is better) finds errors, then increase it.

    on the 1 gig sticks its 1.9,

    So you lied. YOu did not get the exact same sticks. Not only are they a different size, but they are a different voltage and probably different timings as well.

    I don't think your listening. You run them at whatever is says on the sticker. NOT whatever the hell you feel like running them at.

    Hey chill out i sent the 1 gig sticks back and just order the others the 2 2 gig sticks. should be here in 3 days, No i didnt lie, the 1 gig where 1.9 volts, the ones i just orderd are 1.8.just like the ram iam presently using.
  22. You just asked in your 2nd to last post if you should raise the voltage....Did you not??

    You don't raise the voltage. You run it at what it says on the sticker. Period.
  23. yes i did, because i really didnt know, if it would help. but anyway thank you for your reply
  24. uat run the ram at the higher voltage and you should be fine james but you always wanna have the same type of sticks in if you can
  25. What do you mean you run the ram at a higher voltage? You run at whatever it's specs are, no more.

    Where do these people come from??

    he has 1 stick run at 1.9 an d1 at 1.8 so i said set to 1.9 and it should work thats it dont get so pissy

    That's not at all what he said. He said he purchased an identicle match and they are both 1.8v. Pay attention.

    whatever lol i was told by the other guy that it was a 1.9 and a 1.8 stick so dont piss your self jeez

    Well Someone needs Meds, Nasty attitude, doesnt belong on this type forum. (dayto11)<> Yes thats what i said you are correct, it did not work because i mixed ram with diff Voltage, so i bought 2 new sticks with 1.8 voltage, Now its the same :) geekapproved, you remind me off my 3 kids when they where around 16 Bad attitude, they grew up. they have kids of there own now. Iam 58 Retired, Iam done babysitting lol. But thanks for the help lol
