Maybe you haven't read, but this pc is second hand, I have NO clue at all where this PC or the ram has been bought, have no manual nothing... it was inherited from my uncle.

but I'll probably just reformat the drive, reinstall windows, reinstall all neccesary drivers and only install the games that I play often.. but just not now..

about the memory issue, it's going to take a while, atleast a month for sure...
Since it hasn't really been solved, I won't mark it as solved, I will reply in a month whether the new ram cards worked or not..

Ok, thanks - I thought you installed the ram, now I understand it came with the 2nd hand machine. It's better to have all four sticks the same - just make certain you get the correct memory.

Leave the thread open, but don't expect anyone to respond unitl you fix the memory, Ok?

Today's DDR3-1333 has a peak bandwidth of 10666 MHz, which can be improperly rounded down and called PC3-10600, rounded up to be called PC3-10700 or stated without rounding as PC3-10666 depending on the manufacturer's desires.
Hyundai RAM is used in OEM computers, they are just naming it 10700 when most others call it 10600, it's the same RAM.
I would stay with the Hyundai RAM, they came with the computer originally.
Remove the Apacer RAM and run Two Hyundai RAM cards until you can get new RAM. It will run at 1333MHz instead of the Apacer (value RAM) causing it to run at 1066MHz.

As Slartybart mentioned, it's better to have the same brand and frequency/timings RAM.

Let us know when you get the RAM set up correctly.

Thanks Dave. I did not know that. I agree with you now that you've cleared up the 10700 identification for me. It's interesting that the reference says "improperly" rounded down - I suppose proper rounding would be up since the bandwidth is higher than the midpoint (10649).

Anyway thanks, as if it's not confusing enough for the consumer and technophile - you need a degree in mathematics to figure out what memory your machine requires =:> Most stores / sites will tell you the correct memory as long as you identify your machine.



So, the rec is
remove the single Apacer PC3-8500F
keep the pair of Hyundai PC3-10700 - installed in slots 1 & 3.
--> If 1 & 3 beep or otherwise cause issues, install in 2 & 4. Always pair the memory and install in the correct dual channel slots.

Your memory will run at higher speeds - thus a net gain. It's not clear that the Apacer memory is being seen anyway - Speccy and CPU-Z see it, but you stated in post #7, that the system only see 4GB when 3 sticks are installed. There have been many changes (memory installed, memory removed) that I think the best thing to do is staick with one configuration and run that way for a while.

Now that I reveiwed the thread , I see that you originally started with 8GB (2GB x 4) For historical purposes, was the stick you removed back in post 2,3, or 4 another Apacer? Dave's comment on what was installed on the machine is why I ask - it's possible that a pair of economy sticks were part of the OEM. This is not an important question, just one of curiosity.

Furthermore if OP buys more RAM, either a pair of 10600 or a pair of 10700 will match - I think that's a correct recommendation based on Dave's reference.

Uhhm, I've seen this before in this thread, but why are you saying the ram cards are > 1000 mhz?
speccy shows this:
slot 1
Max Bandwidth PC3-10700 (667 MHz)
slot 2
Max Bandwidth PC3-8500F (533 MHz)
^ I know this is still the apacher one, haven't read bart's post yet, changing now..

But as you can see, it shows me 533 mhz and 667 mhz, but you're mentioning double that speed, 1066 and 1333 MHz


so just to be clear:
I will install 2x2GB (hyundai) identical ram cards in slots 2 and 4, leaving slots 1 and 3 open (white),
I will then proceed to use my computer on normal wise, cleaning it too..
As far as I tested yesterday, games are working how they should, maybe 1-2 FPS drop and some more (tiny) freezings.. but that's not a problem to me.

All I got left is one question, what cards do I need to buy, or do I just ask an employee to identify it?

I really appreciate all the help that has been given to me by several members, I learned alot
(e.g. Don't change hardware when power still plugged xD), and I hope this issue will be fixed once I buy new ram cards.

This is what Dave and I agree is the best for now. Cleaning is always good - be careful, dust carries static. A few shots of compressed air (any computer store) is safest way.

See Dave's post and read the link for some general guidance. You can always ask the store personnel, be aware that they are sales people and might steer you to the more expensive items. This is an older machine and might not justify the higher cost of "super" memory. You at least want to match the two sticks you have, higher sppeds won't add much - see some post elsewhere on this thread that describes how the mobo uses the lower speed of unmatched speeds

DDR is Double Data Rate, if the RAM is 533MHz the rate that you actually get to use is double, 1066MHz.

That is the correct cards and slots.

I recommend Crucial, their RAM is guaranteed to run in OEM computers, many have good success with them.
