So guys, my dad gave me his 2gb ram. Now I thought my laptop will become so fast because my ram has increased (4gb before so 6 gb now). Now, instead of becoming fast, may laptop become even slower. I looked at task manager and cpu-z, it says there that my ram runs at 1333 mhz instead of 1600 mhz which is the original speed. Now I looked up online and i found out that I can edit the ram speed on the bios but since my laptop is an oem, i can’t change the configurations in my bios. I found out that you can install a modded bios but I can’t find a modded bios for my model. Guys, please help me. This is my only one laptop. :(((
My laptop model is Fujitsu Lifebook A573/g
Specs:
*Intel Core i5-3230M 2.6Ghz 3rd gen
ME TOO!!!
@Gilian_Kence - Memory does not increase speed of system generally, it may make some work quicker to process but that’s about all. And mixing memory as you noticed can often make things worse, especially if it’s different sizes of memory. Your best bet is to remove this 2GB stick and keep it as a spare, and find another similar/same 4GB stick
Ram speed is controlled by BIOS, or whichever kit has XMP or is in first slot, or whichever is slower. Sounds like you’ve mixed 4GB 1600 memory with 2GB 1333 memory, remove the 2GB and you’ll be set until you get a proper matching memory stick.
Show me CPU-z SPD tab images for both sticks of memory, you can select which slot is shown at top left. Also, show me Memory tab of CPU-z, so three images total, thanks
Okay dude wait I’ll take a picture. 
There you go dude!
This is what I see in task manager
Please edit your posts if you want to add more info and no one has replied yet
Thanks for the images, yes, it’s exactly as I suspected and described in my initial reply.
Additionally, the 2GB you’ve added runs at 1.5V, your original runs at 1.35V so this would be all that is applied to the 1.5V memory too (so that may cause errors, other than being mix-matched with different size, speed, and timings)
Remove the 2GB of memory, this is not ideal combo to run together. Save that as a spare or backup, or to later add to some other system that uses 2GB modules that run at 1333MHz or less.
Well thanks dude. But I really want to use this ram because my ram is only 4 gb. I’m only a poor 15 year old guy with no work so I can’t afford to buy a new one. But anyways, thank you dude. :((
It’s OK, I know you want to use it, but it’s only going to slow system down and cause errors and crashes on you while you’re in the middle of working on something important.
Link me to your stock BIOS and I will look and see if anything can be adjusted. But ideally, I would say the same reply even with all memory ran at same speed, timings, and voltages, due to 2GB does not mix well with 4GB (That kind of situation would be better than current, but still asking for issues too)
Sell the 2GB one, then you’re halfway to a 4GB module

link of my stock bios. Anyway dude, I’ll sell it if you can’t modify the bios. Again, thank you thank you so much dudeeeeeee
Thanks, heading out now, but I will check it when I get back and let you know what I see.
YEEEEEYYYY THANK YOU DUDE! 
Honestly there is nothing to adjust. The two sticks are incompatible in many ways (Voltage, Frequency, Timings, Manufacturer, Size) in order of importance. You can’t use them together. Sell the 2GB stick and get a matching 4GB one when you can.
Also, adjust the tread title to something which accurately describes the problem and do not use Capital letters as it is rude and means “shouting”.
I kinda have to agree with Pluto here. All due I respect that Lost_n is willing to help, it just doens’t seem to get to work together.
And the laptop won’t even be faster after adding the memory and adjusting settings that can’t be adjusted.
Yup that’s my plan. I removes the 2gb stick now.
As I suspected 
, nothing you can do, the only memory speed related setting is this one and it’s on “Auto” by default, and you already know it’s not set to 1333 due to memory being able to run at 1600 Speed with only the 4GB stick
But, even as I mentioned initially, if you could get them to run at same speed, timings, and voltages (which you can’t adjust any of this), they likely would still cause errors due to 2GB/4GB mix and totally different internal IC chips.

Okay dude. Thank you thank you so much! You are very awesome. May God bless you!
