1600 GHz 4 GB RAM on 1333 motherboard

I bought a 1600 GHz 4 GB RAM on 1333 motherboard how will that effect it ??

  1. Ram will slow down to those speeds and probably allow you to decrease timings (make them tighter).
  2. Typically the 'SPD' per DDR3-1333 offers lower CAS Timings so the overall speed is a negligible if at all different. Your BIOS more than likely offers the option to adjust the CAS Timings.

    Use CPU-z (Memory tab is what the RAM is running at currently) and the (SPD tab is the encoded Frequency, CAS Timings and Voltages per Frequency); see - http://www.cpuid.com/softwares/cpu-z.html

    Frequency vs CAS Chart:
  3. ehhhh, all those 1155 boards that say they only take 1333 are lying. they take 1600 with no problems. hell mines running at 1866.

    I can't understand what you are saying , just tell me how it should run and how its running right now in CPU-Z

    If you looked at CPU-z then you'd have an idea what I said. RAM's 'real speed (Performance)' is a function of both Frequency (Higher = Faster) and CAS Timings (Lower = Faster).

    Examples - DDR3-1600 CAS 9 is about the same Performance as DDR3-1333 CAS 8, and the DDR3-1333 is faster if it runs at CAS 7 than DDR3-1600 at CAS 9. Note the Chart above.

    ANS - "how it should run" ; that entirely depends on both your CPU and MOBO.

    Q - What exact MOBO?
    Q - What exact CPU?
    Q - What exact RAM kit? ; I prefer a link or a screenshot of CPU-z 'SPD' tab

    ANS - "how its running right now in CPU-Z" ; I'd need a screen shot of the 'Memory' tab

    (SPD tab is the encoded Frequency, CAS Timings and Voltages per Frequency) ; represents the JEDEC and XMP encoded and Rated specs of your RAM:


    (Memory tab is what the RAM is running at currently) ; represents the Frequency (x2), CAS Timings and Amount of RAM installed.
    Multiply DRAM Frequency * 2 = Frequency to the FSB/BCLK of the CPU, in this example the RAM is running 533MHz * 2 = DDR3-1066

  7. Duh What?! That RAM is a DDR-1333 kit and you're it @ DDR3-1333 now, i.e. it's fastest aka Rated speed.

    Further, I noted 'Single' Channel vs I assume 'Dual' Channel so I'd double-check your DIMM slots. The RAM must be installed in the SAME colored DIMM Slots for Dual Channel to function, and since you didn't post your MOBO I cannot guess which slots to use.

    Hmm...sometimes CPU-z makes a Dual Channel error. You only have (2) DIMM slots so ignore CPU-z.

    Just to triple-check something, post this image of the Resource Monitor:

    Thx alot for your help :)
  10. Looks fine, I assume the majority of the 521MB i.e. ~500MB is going to the iGPU and you don't have a discrete GPU.

    If both are true then you're good! :sol:

    I have ati HD 6850 , but those 521MB are gone because i have Windows 7 32 bit right now , and Thx alot for your help :D :D ;)
