Hello. I need your honest opinion. This is very interesting and COULD BE detrimental to my computer regarding RAM...
For a couple of years now since I built my own ASUS P5Q system, I have been using a total of 4GB of RAM (Corsair XMS2 4GB 2x2GB modules; TWIN2X4096-6400C5) since I was using Windows XP 32-bit at the time. As you know, that is the max. amount of RAM that XP can use for 32-bit (Technically, just over 3 GB.). Several months ago, I upgraded to Windows 7 Professional with 64-bit. Since then, I even purchased more memory, exactly the same type and design I am currently using. The only difference is that the new twin RAM kit is labeled version 6.1 and my original twin RAM kit is labeled version 3.1. Both new and original RAM kits ahve the same 1.80 V ratings labeled on each module. I know my ASUS P5Q can handle up to a max. of 16 GB, so I figured I would take it to 8 GB having 2 sets of 2 kits of the TWIN2X4096-6400C5 modules. So I installed them. For the few months I had 8GB of RAM, the system ran fairly okay most of the time (say 95% good) except for playing longer online videos (like from YouTube) where the system would BSOD and/or the system would freeze during playback (later in the playback). Other than that it ran great. The system seemed more perky than 4 GB! I never modified the BIOS and left everything on "Auto" configuration (like timings and voltages) even after installing the added 4 GB of RAM. However, I never had this random freezing and BSOD happen before since I installed the additional RAM. It always ran great with only 4GB. I have been putting up with this issue for months. Then I decided to get to the bottom of it. I ran Prime95 Torture Test and other software tests to see what the issue was. The system froze exactly 6 minutes into the Prime95 test each time. I decided to take out the added 4 GB of RAM (left with 4 GB) and ran Prime95 and the tests ran smoothly. I played longer online videos with only 4GB of RAM. The videos played smoothly too.
One of things I did is that I looked into ASUS User Guide and RE-CHECKED the QVL (Qualified Vendors Lists) for compatible RAM. I realized I misread the module type in the QVL list before I purchased the same RAM kit thinking just adding another 4 GB to my system would be fine since I know my motherboard can handle up to 16 GB. According to the QVL list, for my type of modules I ALREADY HAD, I CAN NOT add anymore modules. For DIMM socket support per QVL list, these modules do NOT support FOUR modules inserted into both the yellow and black slots as two pairs of dual-channel memory configuration. *ONE* RAM kit only supports *ONE* pair (TWO modules) dual-channel memory configuration per QVL list. WELL, THAT MIGHT EXPLAIN THE ISSUES!!!
Well. I cannot get a refund now and I am stuck with the modules. I wanted and needed more memory too. At 4 GB of RAM, running Prime95 uses ALL the 4 GB of RAM. Also, I do video editing and needed a little more RAM anyways. So I got curious! What if I just install ONE of the TWO modules in the RAM kit (or only add 2 GB) to the already installed 4 GB of RAM for a total of 6 GB of RAM? I would have more RAM (greater than 4 GB)! Would that be okay? BUT WOULD MY SYSTEM BE STABLE??? I knew that my system was "fairly" stable at 8 GB most of the time. Lowering to 6 GB, but more than 4GB MIGHT be a good choice.
I added ONE 2 GB RAM module to the second DIMM slot between the other pair. I ran Prime95 at 6 GB of RAM since Prime95 always seemed to catch issues. RESULT: NO ISSUES!!! Prime 95 ran smoothly. I notice that using 6 GB of RAM, I was left with at least 50% free unused RAM even using labor intensive Prime95. I figure I should be fine for video editing now. I have ran several long You Tube videos for testing purposes. NO SYSTEM FREEZES EITHER!!! I figure my system is stable at 6 GB of RAM FOR A SHORT TIME NOW. My system seems more perky now than with just 4 GB of RAM. I did not make any modifications to my BIOS either.
What is your honest overall opinion of this scenario??? Do you think I am okay or not with 6 GB of RAM???
Please reply!
Thank you!
Some basic general stats of my system:
- Windows 7 Pro 64-Bit.
- Intel Core 2 Quad Q9550 -- Yorkfield 2.83 GHz 1333 MHz processor.
- ASUS P5Q desktop motherboard.
- 6 GB of Corsair XMS2 3x2 GB DDR2 RAM.
- XFX Radeon HD5670 GDDR5 1GB RAM Graphics Card.
