Aspire V5-573P - upgrade 1600Mhz memory runs at 1333Mhz

I was wondering what kind of memory you all purchased for your Aspire V5-573P or Aspire V5-573G if you have successfully gotten it to run at 1600Mhz. You can check your speed using CPU-Z or memtest86+ (it should report around 800Mhz give or take a few).

Sadly, I have had a lot of trouble finding the right memory, and it's frustrating especially since it takes 17 screws to get to the ram.

The soldered on memory is: 1600Mhz 11-11-11-28.

First I got g.skill cas9 1600Mhz 4gb. I just assumed the timings would get dropped to cas11. Sadly, the bios defaulted the speed to 1333Mhz. Since then I've read that you should try to match the ram as much as possible so the bios doesn't go to it's default setting at 1333Mhz. I purchased Crucial 1600Mhz cas11 memory. I noticed that upon first run, it does run at 1600Mhz. However, if I power down the sysytem and restart, it defaults to 1333Mhz. The only way I can get it back to 1600Mhz is by holding a pin to the battery disconnect button/hole on the bottom of the laptop. As long as I don't power the computer down, the ram stays at 1600Mhz (checked with memtest86+ and CPU-Z). Restarting is fine as long as it's not actually powered off. Once it's powered off, it will default 1333Mhz. I'm guessing the bios analyzes the ram switches to it's defaults when the system is powered off? I really wish the bios had options for the memory, it's been a real headache. Any feedback?

Thanks!

I am sorry to say I do not have an answer for you (and have found this forum to be virtually worthless when it comes to getting help, whereas 30 seconds after asking a question on Toms Hardware *in any forum there* I have an answer and within a half hour I have several answers confirming whatever I needed to know... )

But I am also very interesed, I have a new V5-552PG-X469 and am considering upgrading to both a SSD and the RAM at the same time (as I also just had to remove the damned 17 screws when my laptop froze up for the first time and I had no way of restarting it...) and I am not 100% sure what RAM I should be buying, I have basically the same question as you .

Hard to find out the difference between simply "compatible" and actually compatible/maximum return for the dollar (Why buy the high performance RAMs if they won't run right, right?)

Hey, yeah the help doesn't seem plentiful here yet hopefully it will come.

Did your computer not turn off even when holding down the power button? If not, then I think your V5 (if like mine) has a tiny hole on the bottom of it with a engraving of a battery being removed, if you have a paperclip, you can stick it in there and it should temporarily disconnect the battery so you don't have to open up the case. Be sure to disconnect the AC adpter before doing this.
