Solved combining 2 different kinds of RAM?

February 8, 2020 at 17:26:31
Specs: Windows 10, i5-4570 / 8 GB
Hello, i got an ASRock B85 Pro4 Motherboard, which accepts
4x DDR3 DIMM, dual PC3-12800U/​DDR3-1600, max. 32GB (UDIMM)

on it already installed is
Crucial Ballistix Sport DIMM Kit 8GB (2 x 4 GB), DDR3-1600, PC3-12800U CL9-9-9-24

Now the question: i got a spare RAM:
G.Skill DIMM Kit 8GB (2 x 4 GB), DDR3-1333, PC3-10667U CL9-9-9-24

Beside it may be not optimal due to different specifications, could there be any problems if i install it or wouldn't it really matter but have more benefits than disadvantages (simply more RAM)?

Typically once the system detects new RAM it will reset to the slower settings for the memory available.
If it does not then you may need to make changes to get it to run properly.
In order to get them to run at the faster setting you would have to reset that yourself manually. Understand that in order to get the slower memory to run at the higher setting you will probably need to slightly up the RAM voltage (+0.02V typically) or loosen up the individual Timings (Latency from 9 to 10 say, etc.). This may take some experimenting so run it slower or have time to do it and patience.

You have to be a little bit crazy to keep you from going insane.

Just try.
Best you look at your System page first & note what is accepted, then try.

It should work. The lower rated 1333 RAM will dictate the speed but you might be able to override it in the BIOS to make all sticks run at 1600.

Also known as overclocking

Comes with a price obviously. In general, you should know what you are doing, and more importantly : you should be prepared to take the risks.

If anybody could just let everything run faster, just like that, it would be easy.

thanks for the answer, just one more thing ... the PC is not for gaming or other demanding tasks, it's mostly for office, videos and maybe some low profile games (like online games or things like train simulator 2012).

So let's say i stick the higher rated RAM into the board without adjusting the clockspeeds and leave it be ... will there be any real life effects in speed that are recognizeable (for the defined tasks) using 1333 instead of 1600 or is doubling the RAM size outperforming such effects (if there are any anyway). Plus: Are there settings i should change in BIOS while not overclocking or will the RAM just be put to 1333 and that's it?

I just think that why risking anything by overclocking, if it wouldn't have any considerable effects in real life ...

It should work exactly, but the frequency of memory operation will be lower than we would like.

see how far you can go, with 1.65v :))))

Hi, thanks for all the replys, i really appreciate your efforts

meanwhile things have changed, i turned out that at least one of the RAM sticks was malfunctioning (i discovered this while trying to install windows 10 and getting the error code 0 x 80070057.

so i have to throw the ram into the trash bin and just use the 8 GB ...

Sometimes you can get them to work again if it is only the contacts that are causing the errors.
Clean the contacts on the memory stick with a soft clean pencil eraser, wipe off the dust from the eraser, pop the stick into and out of the socket 4 or 5 times to burnish the contacts in the socket.
Test with Memtest86 or Windows memory tester.

Thanks for hints Fingers, such tips may turn out useful for someone with similiar problems - unfortunately i can't try it anymore with my RAM as i disassembled the PC completely to sell the functioning parts over the internet ...

While more memory will always help an old tired system there is no substitute for newer better hardware. I hope you get enough for the hardware where you consider a new build and something much faster. If you do, create a new thread here with your chosen hardware for suggestions to possibly improve on your choices within your budget. Thanks for getting back to us.
