RAM Sticks Sloth order 1-3 vs 2-4 importance?

Hi,

Today i added 2x 2GB 800Mhz CP5 (different brands) to my existing dual channel 2x 2GB 667Mhz, the computer turned on just fine, Windows 7 detects 8 GB of ram as it should.

My other question is the order in slots, i had the dual channel rams in slots 1 and 3, so i intsalled the new ones in slot 2 and 4, is the order important, should i put the dual channel RAMs in slots 2-4 and the rest in 1-3?

The motherboard is Gigabyte GA-EP35-DS4 (http://www.gigabyte.com/products/product-page.aspx?pid=2744#ov)

Also i noticed a problem with my Google Chrome browser, when i tried to save an image with "save as" option the save and cancel button there didn't work, all the rest worked, i could change directory, file name, all work expect the Save and Cancel buttons in bottom right corner of the window. Can this problem be correlated to the new installed RAM?

  1. Best answer
    With Dual Channel it doesn't matter besides having 2paired ram in the correct slots, 1-3 or 2-4 it doesn't matter, but there is an issue with your ram itself, (I'm not the most tech Savvy person so i may not be 100% correct on this, but from what i have read over the years this is my understanding).
    but the issues here are that
    1: having 4 sticks of ram in 2 different Dual channel slot, won't improve the performance, if anything hinder it, you can still run all the ram slots in unganged mode and take advantage of the bulk amount of ram, only time 4 sticks or ram work great like that is when the motherboard supports quad channel ram (the board will have 8 ram slots) and its best to get a quad channel kit for them
    2: cause your 800Mhz ram is 2 different brands their timings may be not correct to each other, so again best to run in unganged mode
    and finally 3: cause you have 667Mhz ram installed it will bottleneck the 800Mhz ram down to 667. i tried and tested this years ago, with my AthlonX64, the slower ram bottle necked my cpu!

    to see how your computer is performing i would recommend 1 program, CPU-ID (i get the ROG version, it looks fat) http://www.cpuid.com/downloads/cpu-z/1.68-rog-setup-en.exe click the download now, then you can see how whats reading and even validate it and post it on forums eg: my 6 year old beast http://valid.canardpc.com/7nyrxi

    as for your issue with Chrome, i am unsure about that one, not a very software savvy person!

    Well i hope you find my answer helpful, and if anyone else reads this, please inform me if i am incorrect on things, i can take it!
  2. Thank you for info, i made CPU-Z validated report(http://valid.canardpc.com/jymg9r). I was wrong about the Mhz of dual channeled ram, they have 400Mhz, not 667Mhz.

    Also why is it showing my CPU Mhz to be 1600Mhz, it is a 2.40Ghz quad core, shouln't it be 2400Mhz?

    Hmm a few things, it may read your ram as lower, this part i don't fully understand, is that it reads you rams speed at half, eg look at mine it says 805.4 MHz this is cause it gets multiplied by 2 for some reason (but this maynot be the way your system is), and as for your CPU to get a proper reading on mine, i started a cpu stress test, cause otherwise it read it at idle speed which is ALOT lower!

    it actually says up the top Intel Core2 Quad CPU Q6600 @ 2.40GHz, the other readout was a snapshot of your cpu at that current time! eg look at the picture of cpuid beside all the stats, see where the multiplier is, it only says x6 (6-9) means your computer is currently at its idle speed!
  4. In CPU-Z if i check each ram stick seperately it show all 4 are running at 400Mhz, im fine with that, tried few games like Call Of Duty and opened tons of windows in Google Chrom + Firefox, it runs smooth, im happy with it at 400Mhz speed for now, and will not put it to Ungaged mode because Inter doesn't support it, also i need it for games so i will leave it as it is for now.
