Solved

The speeds of ram, motherboard and CPU are different!

First of all, I am newbie and the case is, I bought a new motherboard and a new set of ram to upgrade my computer.
New motherboard : Asrock G41M-VS3
New set of ram : 2x2gb DDR3 1600mhz ram
Old CPU : Pentium dual core E2180 (FSB 800mhz)

My questions are:
1. The new motherboard supports max 1333mhz memory, but now I have a set of 1600mhz ram, will there be any problems when they are in use together? Do I need to do something with the FSB1 jumper setup?

2. The old CPU speed is only 800mhz, but my ram speed is 1600mhz. What would happen to the ram speed when they are in use together?

3. Is it not preferable to use a high speed ram with a low speed cpu? Because the difference between the speeds seems quite big.

Sorry in advance if the questions are stupid to you experts. I am a newbie and I really need your help, Thanks!

  1. On ram most ram have an EPROM with a few stock ram speeds flashed into the ram. On 1600 and faster ram the ram top speed is set in the EPROM called xmp profile. If your mb bios has that setting some older mb can run 1600 DDR three ram. If not it default to 667 speed the default speed of 1333.
  2. What it will/can run at will depend on you and your skills, to run the sticks at 1333 will require the FSB also run at 1333, this will OC your CPU quite high, which you should be able to lower via the multiplier, will also require additional CPU vCore and NB voltage for the MC Memory Controller, good possibility will need additional DRAM voltage also - not positive if your mobo has a locked FSB or not (if it doesn't you could venture higher)...I remember the early 680I mobos were supposedly only able to go up to a 1333 FSB but many were pushed to 1600 and higher especially the Strikers and XFX mobos, but they weren't G41's obviously

    Thanks for replying.
    But what if I only want the CPU and rams to run at 800 only? Because I am worried that OC will severely damage my already-quite-old cpu.
    Btw, what would be your preference if you have these hardware? Will you OC it to 1333 or to other speeds, or not oc it?

    By default the DRAM (if it boots and it should will boot to the mobos default which is is prob 800, not positive how stable it will be, if any problem give a shout, may want to tighten timings regardless for a performance increase

    So, just to make sure, I can put all these 3 things together and it will run properly, but not sure how stable the performance will be. Am I right?.
  6. Yep - it should

    Thanks a lot. Sorry for asking so many questions.
  8. No problem, if it was a bother I wouldn't be here ;) Can prob go ahead and close the thread, have a good one !
