    Ronnie Pickering reacted to mariushm in Which ram mix is worse ? ddr3 1,5v with ddr3l 1,35 or 2 different brands matching speed and size 1,5V?   
    The DDR3L stick MAY run at 1.5v but keep in mind it's technically overclocking it.
    Some memory chips may not like running at 1.5v and the stick will be hotter in general.
     
    I'd say it's not worth mixing ddr3l with ddr3
     
    You DO NOT have to install sticks of same brand, or same series.
    You can even buy 1866 Mhz memory sticks and run them at 1600 Mhz - memory sticks have multiple presets built into them, the default high frequency (the advertised specs) one and multiple JEDEC compliant presets (1600 Mhz, 1333 Mhz, 1066 Mhz and even 866 Mhz or 667 Mhz in some cases). You are not restricted to using the higher frequency, the sticks will run perfectly fine at the lower preset.
     
    Some sticks are advertised at 1.65v but only need 1.65v for the high frequency (1866 Mhz) and can run perfectly fine at 1600 Mhz with 1.5v
     
    From your previous post history it sounds like you're from Bulgaria? in that case, no clue what shops you can use... but if you link to some online stores you can buy from I could give you some suggestions

    U-DIMM simply means unbuffered DIMM ... unbuffered memory which is the standard memory used in desktop computers.
    Other types are
    ECC Unbuffered DIMM (contains an extra chip on stick for error correction) - these may or may not work on your board with the error correction functionality being ignored
    FB-DIMM ... fully buffered dimm  and Registered DIMM   / RDIMM - these are used in servers.
     
    CL is just a latency parameter, a smaller number is better but it's not really critical or important to you ... it matters mostly in applications that have to read and write lots of very small amounts of data into memory... think databases, web servers... for gaming and every day use it's less important.
     
    All sticks have a bunch of parameters that change with each frequency.. one of those parameter is the CL value ... these parameters along with the frequency and the voltage define a profile or preset ... and each memory stick has multiple such presets stored in the ram stick in a very tiny chip.
    You can see those presets using CPU-Z for example, or Aida64 ... in CPU-Z, click on the SPD tab and you'll see the presets/profiles there (most of them)
     
    If you mix memory sticks, the motherboard (well the bios) will pick the best profile that is supported by both sticks and go with that.
    For example, the laptop i'm typing this message on has two memory sticks installed in them... one rated for 1600 Mhz and one for 1333 Mhz :
     

     
    So you can see the Samsung one can do 1600 Mhz (2x800Mhz) with the profile titled JEDEC #7 ... which tells the bios to set the timings to CL11 (11-11-11) and 1.5v
     
    The second stick is only rated up to 1333 Mhz (2x666 Mhz) and the stick contains TWO profiles (JEDEC #5 and JEDEC #6) which differ only on timings (the JEDEC #5 is better performance, ever so slightly better).
     
    So in my case the BIOS has no choice but to go with the highest frequency supported by both sticks, which is 1333 Mhz.
    Now it compares the profiles and picks profile JEDEC #5 from the Samsung stick (because 685 Mhz is bigger than 666 Mhz), and JEDEC #5 from 2nd stick so the timings 9-9-9-24-33 will be used.
    In the Memory tab I can confirm that :
     

     
    This is why I say you can also buy sticks with higher frequencies like 1866 Mhz or with higher voltages like 1.65v, because they'll have some profiles/presets (whatever you want to call them) which will have the standard 1.5v voltage

    I mean you can't exactly go wrong by picking a new 80+ rated power supply from a trusted manufacturer (except EVGA's 80+ white PSU's). Because I've never exactly heard horror stories about power supplies from EVGA, Corsair or Seasonic for example.

    Agree.
     
    Disagree. Brands means nothing, the model is what's important

    500W is fine for an i5 and a 580. That being said, I would agree with the other posts that that particular PSU is a little sketchy, and I would suggest something at least 80+ bronze
     
    You can definitely try it if you already own the PSU. If you come into power limit issues, your rig will just lock up or crash when gaming. It wont likely damage anything, as the components have built in protections. (I wouldnt recommend it though)

    A 500W power supply does work perfectly fine for the system. The thing is that your power supply isn't exactly great, it's a legacy product and it's questionable how reliable it is. I'd recommend replacing the PSU with essentially anything 500W 80+ bronze from a trusted manufacturer like Corsair, EVGA, Seasonic and others.

    Hello,
     
    No it will not, 500W that can only deliver 360W is awful.
     
    Get something better like a Corsair CX 2017 550W.
