Acer Helios 500 - RAM upgrade

Member Posts: 17 Troubleshooter
hi everyone,
i'm seriously considering a purchase of Acer Helios 500 with Ryzen 7 CPU. Apparently it's an issue to have Ryzen 7 CPU paired with RAM with frequency set to 2400 Mhz. I'm no expert in this matter, but i've heard it's a limiting factor for AMD Ryzen. I've seen reviews criticizing Acer for putting such a slow memory into this model. So i consider replacing out of the box memory sticks (2 x 8 GB 2400Mhz) with 2 x 16 GB 2666 Mhz CL 15. Are there any manuals describing how to get to less accessible RAM slots where stock RAM sticks are mounted?

Hello,You'll find informations in this procedure:0

thanks for your reply. The problem is that i want to replace 2 stock RAM sticks with more capable components. This laptop has 4 RAM slots. Two are occupied by stock memory sticks, the other two are free and easily accessible (as described in the link you provided). So the trick is the get rid of 2 slow memory sticks in the less accessible area.0

sri369 said:Out of curiosity, are you intending to replace these cos some reviewers said 2400 is slow and should use 2666, or did you feel that the system was infact slower than what it is supposed to be?0

skyrunner86 said:I want to have as capable piece of hardware as i can without limiting factors. If i hear, that 2400 memory isn't working well with the AMD CPU, then it's a thing to get rid of for me. I will also replace mediocre SSD as well as HDD, but this is not a problem - IF i decide to buy this laptop. I don't own this laptop yet, if it's too difficult too replace those sticks i will simply buy something less problematic to reconfigure.

- Acer memory specs:
1 of 2/CH (xR-0) : SR(2667), DR(2400-2667) MT/s
2 of 2/CH (1R-1R) : 2133-2400 MT/s
2 of 2/CH (2R-xR) : 1866-2133 MT/s - AMD Ryzen™ 7 2700 memory specs:System Memory Specification: 2933MHz maxi
The two other memory slots are located on the other side of the motherboard (under the keyboard) so it will be a big work to change these ones:

For me i guess it's a bit too much of work but i could take it to some laptop repair service and they would do it without any problems. I just wonder about Acer warranty if i decide to replace those. Acer has their official service center in my city so i could take it to them if it would void warranty otherwise. I guess i can call Acer to figure this one out.

skyrunner86 said:Thank you for this information, Laurent. I'm not entirely sure how to interpret information you provided, in terms of what is the max frequency i could put in there. You mention AMD memory specs, does this mean i could insert 2933 Mhz?Hello,I understood the Acer specs like this:
- 1 of 2/CH (xR-0) : SR(2667), DR(2400-2667) MT/s
Simple ram: 2667MHZ maxi - Double Ram: 2667MHZ maxi in the same channel - 2 of 2/CH (1R-1R) : 2133-2400 MT/s
1 Ram + 1 Ram in the both channels: 2400MHZ maxi - 2 of 2/CH (2R-xR) : 1866-2133 MT/s
2 Ram + 1 or 2 Ram in the both channels: 2133MHZ maxi
The AMD specs were just for information. The maxi frequency will be 2667MHZ in the first memory configuration.. no more.0 - 1 of 2/CH (xR-0) : SR(2667), DR(2400-2667) MT/s

2666MHz RAM would compliment the Ryzen system best (at price to performance).
Also as mentioned before the existing RAM is located on the bottom side of the motherboard. Meaning you would have to remove all components inside to get to flipping the board over revealing the RAM slots.- Hotel Hero0 -
I too am interested in this. Looking to get the laptop and pair it with 2x16 GB Hyper X sodimms, but want to know which pair to get. If it is limited to only 2400 no matter what, the CL14 pair would seem the best option. However, faster options would be better to speed up inter cpu communication (2667 CL15 and 2933 CL17).0

Edit: Re-read it. Was mistaken, thinking of the configurations wrong in my head.0 - 1 of 2/CH (xR-0) : SR(2667), DR(2400-2667) MT/s

OK, so the laptop came today. 2 x 8 GB 2400 Mhz inside. I started AIDA64 to check and it tells me the following thing:
The highlighted part is described as "Supported Memory Types". As you can see it's a pretty impressive list ending at 3200 Mhz. So is this information reliable in any way?
I've found this post online:

The occupied slots can be upgraded to 2666MHz according to service guide (some come with 2666MHz from factory).
The empty slots can also be 2666MHz.- Hotel Hero0 -

Well, increasing RAM speed mostly doesn't result in any performance gain:It's the best way to waste money. That being said, I was able to overclock the factory Hynix DDR4 2400Mhz to 2933Mhz (21-21-21-43) by modding the bios (to unlock custom memory settings):The performance improvement was barely noticeable. I'm running 2x16GB G skill 2666Mhz along with the 2400mhz sticks right now, everything at 2666Mhz (19-19-19-43). That's a total of 48GB, with 24GB on each channel.If you want to fully exploit 3200Mhz RAM, then you will need to mod the bios and remove the factory RAM by entirely disassembling the laptop. Not easy but feasible. You may see 0% to 5% performance improvement.
