Two different kinds of memory


So I have 8gb of Viper memory, the problem is it is interfering with my CPU heatsink. Basically it is the memory is too tall for it.
The other problem is one I learned of too late. It is 1.65v, when I should've got 1.5v.

So, what I wish to purchase is another 8GB of DDR3 memory, 1.5v. My concern is that it it won't mesh well with the 8GB I have already. I am even considering getting a cheaper 4GB set of memory.

My biggest motivation for this is overclocking, but I would like to have my fan sitting properly on the heat sink. Any information would be appreciated.

  1. What's the Mobo Model, the HSF model and the exact memory Models?
  2. GIGABYTE GA-Z68X-UD5-B3 LGA 1155
    Patriot Viper Xtreme Series, Division 2 Edition 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 1.65v

    As for the memory I'm looking at.. well I haven't decided. I made an ill informed decision once, and I didn't want to repeat that mistake.
  3. What about the CPU HSF? Is it the standard one out of the box or is it an after market cooler?
    If it's an aftermarket cooler, then which one? Make and model.
    Errr another thing, have you check it's memory QVL, 'cos I haven't been able to find that 8GB Model in it, as a matter of fact I haven't seen a single 8GB Model in that list, although the Specs say it supports upto 32GB Max in those 4 Slots, meaning the Max each slot has to support is 8GB, true, but it's till a hitch which I don't like very much. Please confirm you have it in your knowledge that you have read that that particular RAM stick is working on your Board.
  4. I have a Cool Master Hyper 212 Plus

    I don't think it should be that much of a hitch since I plan on getting 2 4GB sticks.. I don't need more than 16GB in this computers life time.

    I was looking at getting Patriot memory now since it doesn't have a ridiculous heat spreader and is cheap at 1.5v Though it does not appear on the tested list, although neither does the memory I have in there now.

  5. If the fan on the HSF does touch the top of the heatsinks of the RAM , you can always move the fan to the other side of the HSF.
  6. The problem with that is my case. I have a raven 03, if I move it to the other side i need to make holes on the other side of the fan so that it pulls hair through the heat sink.

  7. If this is the case, I don't think you need to have to drill holes anywhere, they already have fan supports in three direction which is the normal for most cases.
    Where do you think you'd have to drill holes? A pic would be pretty helpful.

  8. I mean in the heatsink fan. There is plenty of space in the case.
  9. WOW!! I'm lost? I have never heard of anyone even thinking of drilling hole in the HSF assembly. Would it be possible for you to post a pic/few pics here of you HSF so I can get an Idea as to why you feel you would need to drill holes and where is the thing closed from? 'Cos they ain't supposed to be closed from anywhere it's supposed to be a fan, pulls air in one side throws it out the other.....
  10. I will try to get some photos up in the next day or so, but most people don't need to drill holes in the fan because the way the fan is situated is typically important... whether it is up or across. Because of this cases layout, it must blow up, so to put the fan on the other side of the heat sink the fan would blow down, against the airflow. The fan doesn't have threaded holes on the other side so that it could pull air through the heatsink.

    Before we make this more complicated, my memory is running at 1333 instead of 1600 because of the voltage and my i5 processor. If I were to buy another duel kit, whether it is 4 or 8 GB that is 1.5v, would I notice a difference? I am not hoping it will go faster because I know even 8GB is over kill, but I just want to be able to overclock my processor to upwards of 4GHz and still have my memory run at the very least at a rate of 1333.
  11. Just flip the fan the other way round.

    After you turn the HSF the other way you can remove the fan and put it on the other side and reverse it....
    Or Whatever.... it's got mounting Holes on both sides....
    What are you really talking about???

    And know you'll not notice the difference.
    But, if you were planning on picking up a new set of RAM I'd suggest going in for the same make and model of the earlier RAM or atleast the same Capacity, timings and voltages if you want to use them with your earlier RAM.
    The SB has a Memory Controller On-chip so lets not complicate things for the processor while we are going to be making changes in the Mobo Bios too..... meaning OCing....

    You cannot have 2 x 1.65V Modules and 2 x 1.5V modules.....because the 1.65 ones as it is are being under volted to get them to run at base speed, you'd end up under volting the 1.5v ones further..... to give you way too many BSODs....
