RAM Memory

    You are right, I did not run the test long enough... It only did one pass which only lasted about twenty minutes so I will run it again and leave the comp on overnight. I just thought one pass would be enough... Obviously, my ignorance on these grounds played against what would have been the right thing to do... I will let you know about the results tomorrow.

    Regarding the voltage thing, I can only up it to 1.2V, the BIOS will not allow me to go any further, which I put down to the fact that the PSU must not meet the minimum requirements. However, when I run the "Memory Diagnostic Tool" Windows-native application in standard mode, it gives me the "There were hardware problems detected" message after running for only a few minutes so I guess I must do something about it.

    I have another query on the PSU matter... Can I get it replaced without having to change the computer case? How much can it cost me and what should I have to say to the computer shop assistant so as to get the right PSU?

    To finish up... Can I damage the computer if I keep the 300W PSU? I do intend to get it replaced so that I can enjoy the 16GB of RAM I initially purchased, but in case of it being dangerous to run the computer at such low power, I will just not use it until I get it changed.

    Thanks for your help...

    It is strange. Here's the spec for your MB: GIGABYTE - Motherboard - Socket 1155 - GA-H61M-D2H-USB3 (rev. 1.0)
    and under specification tab for the memory:

    1. 4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory
      * Due to Windows 32-bit operating system limitation, when more than 4 GB of physical memory is installed, the actual memory size displayed will be less than 4 GB.
    2. Dual channel memory architecture
    3. Support for DDR3 1333/1066/800 MHz memory modules
    4. Support for non-ECC memory modules


    In item 1. It says 1.5V and yet you cannot up the voltage. That leads me to have some doubt if the Kingston RAM is compatible with your MB. Your MB manual usually will list all the compatible RAM from different manufacturers that you can use. If it is compatible, is there an XMP option in the BIOS for your RAM ? if so, set that option to see if you can up the voltage. If not then definitely you might want to look for another PSU, I would no matter what.
    I am not sure what your budget is but since you've already upgraded your MB,RAM, CPU and having a good quality case with good airflow, ventilation is also a plus. HP built their cases to fit their customized components and makes them look nice, unfortunately most will not provide adequate airflow.

    PSU. If you decide to re-use the HP case then you need to take into account the size of the PSU, read up the specs and find out if it would fit into your case. Antec or CoolMaster are the 2 popular PSU manufacturers that most people use. I am using both Antec 850W/CoolMaster 750W and very happy with them.

    No, there is no such an option in the BIOS, which leads me to think that what limits the RAM memory performance is not its compatibility with the motherboard but having such a low-consumption PSU. I have already talked to the shop where I got the RAM, CPU and motherboard and the one in charge told me there is an 800W PSU in stock that fits perfectly into my case, so I will take the computer in and have the PSU replaced.

    Good. 800W is even better and don't forget to run memtest86+ again, over night. Please report back and let us know how it goes.
    Good luck !!!

    One last sanity check here.. I'm still a bit concerned because you stated that you did not know how to effectively change the RAM voltage. So, is this where you attempted to make the changes (see image) in your BIOS because it sounds like you may have been trying to change a "different" voltage.

    So, if that is where you were trying to make the change, and it only offered a maximum of 1.2v change, I'm lost because I don't think an upgrade to an 800w power supply is going to fix your problem and I really don't think the cost (for having a shop put one in for you) is justifiable for the following reasons. IMHO, your 300w power supply is adequate for the specs you have listed. Now, if you can't fix your current problem by upping the voltage, and your rig is running fine with 3 sticks, then I'd let it run "as is" and save the "extra module" for future use. So, if you end up being satisfied with the 3 sticks and the current power supply, you probably aren't missing much because 16GB of RAM (compared to 12GB) is not going to give you a noticeable boost in performance unless you do some heavy-duty gaming and/or graphics/video manipulation. Now, in my case, I do, from time-to-time, get into some heavy-duty video modifications and I have never had a problem on my Windows 7 rig using a paltry 8GBs of RAM. So, in summary, make sure you were in the right place to attempt the voltage changes and then decide whether or not to replace the power supply and "see what happens." Good luck.

    First off, thanks so much for your thorough explanation... I truly appreciate it.

    Yes, that is what I changed, the DRAM Voltage. I found it odd that I could read, up above all the possible options, 1.5V yet the options below it were as follows:

    - Auto
    - Normal
    - 1.120V
    - 1.140V
    - 1.160V
    - 1.180V
    - 1.200V

    I tried 1.160 and then 1.120 without success, then I quit trying, thinking it was so weird that it stated that the voltage memory was of 1.500V but still didn't allow me to get anywhere near there.

    Someone in this thread hinted that if I changed the PSU, the problem should be solved due to the low-consumption PSU I have at the moment.

    The computer seems to go smoothly with three sticks, but when I run Windows Memory Diagnostic Tool, it ends up with the "There were hardware problems detected" error, which triggers me to think that there must be an HP hardware component that has become either obsolete or too poor for all the changes I've made inside the case. Any ideas as to why the Windiws Memory Diagnostic Tool gives me the error?

    Sorry I missed the fact that your Windows memory diagnostics failed even though you PC runs OK. However, I'm still somewhat apprehensive about replacing the power supply so I would ask you to try this test (if you are so inclined). Test each memory module individually by installing only one memory module (at a time) in slot DDR3_1 and run your windows diagnostic on each stick as well. Also, I don't know who installed the power supply but I'm hoping your old power supply provided a straight 24 pin to 24 pin connection to the mobo (there should be no pins showing on the main 24 pin mobo connection). In summary, if all of your memory tests OK, and the Windows diagnostic results are important for you to resolve, then I'd definitely agree with topgundcp and say go for the new power supply.

    Weird. There's a QVL (qualified vendors list) for your motherboard:

    http://download.gigabyte.eu/FileList...m-d2h-usb3.pdf

    It has a couple of shortcomings: all RAM is downclocked to DDR3-1333 rates, and there are no listings for 4 DIMMs.

    KVRN9S8/4 doesn't seem to be a Kingston part number, at least as far as Google knows. KVR indicates Kingston Value RAM, but there should be more characters in the part number. Example: KVR1333D3N9K4/16G is a 4 X 4GB memory kit.

    Sometimes, when I was running 4 DIMMs, I had to back off the timings one tick. Some motherboards are stressed if all 4 DIMM sockets are populated. (I see nothing in the FAQ for your board on that, though.) For that, you'd have to set the RAM timings manually.

    I took for granted when OP said he has 4GB Kingston SS and also mentioned about Memory Compatibility in my earlier post and looking at the list, I don't see any 4GB Kingston SS module.

    @Nando
    Can you double check who your RAM manufacturer is ? If it's not Kingston and it's not on the compatibility list then it might have explained why you could not adjust the voltage.

    Nando,

    Please download and run this portable utility, HWInfo32, so your RAM can be properly identified:

    HWiNFO32 Download

    Just unzip it, run it, and post the RAM details as shown below:
