    I would like to find 1333mhz memory that do not reduce their timings when running at 1066mhz.

    Basically I want 1066mhz with timings like 9-9-9-24.

    I don't quite understand the question. Usually memory will run at better timings at DDR3-1066 than at DDR3-1333.

    Wikipedia ( http://en.wikipedia.org/wiki/Ddr3) says that standard latencies for JEDEC DDR3-1333 are 7-7-7-24, while they are 7-7-7-20 for JEDEC DDR3-1066.

    idk about laptops but with desktop memory it's quite common that you can get better timings if you operate it at a lower rate.

    I want my ram of 1066mhz to have timings like 9-9-9-24, the standard of most 1333mhz. However, most 1333mhz memory will reduce their timings when running at 1066mhz. (my needs have nothing to do with getting better performance).

    By "reduce their timings," I suppose you mean more favorable timings. Just to be sure you understand that for example 9-9-9-20 is better than 9-9-9-24. So I understand you basically don't want to run to have those more favorable timings at DDR3-1066. :confused:

    The answer is, since laptop BIOSes (in contrast to desktop BIOSes) typically don't allow you to set RAM timings, you need to do this using software. memset for example. EDIT: i just googled and it seems memset is out since it doesn't support your chipset. (assuming you have an i7)

    Memset doesn't allow change of cas. I have a qx9300, so memset does work, but not good enough.

    LOL. You have this funny quote in your sig.

    But then you make this weird post. I suggest being a bit more verbose next time, stating what processor you have, that memtest didn't do the trick, etc.

    Also, perhaps work on your English a bit: the OP sounds as if you want to find those new memory sticks that don't change their timings when you go from 1333 to 1066.

    Your statement was as meaningless as your complaint. If it is an English thing, then you'd have to first determine exactly what he meant, then give him a better way of stating it to avoid misinterpretation in the future.

    For the record, English is a very complex language even for native speakers.

    @Krane: I didn't intend to troll. But Darth Bane's original post misses a lot of information. It took me two posts to understand what OP wanted. When I gave him the obvious suggestion (use memset), he told me that it wouldn't do the trick for his specific problem.

    Usually, that's all fine and I wouldn't bother. But OP has this witty sig which talks about the etiquette/netiquette of helping someone. Given that sig, I consider it fair game to tell him about the etiquette/netiquette of asking for help.

    Really, i thought my first post was quite clear.

    All I want is someone to point me to some memory that doesn't reduce/change/alter/insert-your-word-of-choice their timings. I didn't ask for software alternatives like memset. It's a basic question that just needs a basic answer.

    If nobody knows, please let this thread die peacefully.

    I got you. But I wasn't implying you were trolling?
