G3-571 RAM wich is the minimum CL latency and max frequency for G3-571 mobo?

dighi · June 2018

Hi, i would like to upgrade my 2x8gb DDR4, 2400 MHz, No ECC, CL17, X8, 1,2 V, nobuffer, SODIMM, 260 pin. and replace them with 2x16GB HyperX Impact HX424S14IB 16 GB, 2400 MHz, DDR4, CL14 SODIMM o\r even HyperX HX426S15IB2K2/32 Impact Memoria RAM, 2666 MHz, DDR4, CL15

may i ask you for minimum CL and maximum Mhz supported from G3-571 motherboard?
thanks

Hi,
The maximum speed supported is 2400MHz and the HyperX Impact 2400MHz DDR4 CL14 memory module might be the right choice, I couldn't find any max/min value for CL.

According to Crucials website (Acer's partner for the Helios) RAM can be upgraded with 2666mhz DDR4 with a CL of 16

Kingston lists the memory in link below as being compatible. I don't see your HyperX on the list.

https://www.kingston.com/us/memory/search?DeviceType=3&Mfr=ACE&Line=Predator&Model=97103

The JEDEC DDR4 2400 timings are in link below. More than likely, your computer will only run at JEDEC DDR4 2400 (or 2133).

https://en.wikipedia.org/wiki/DDR4_SDRAM

Here's the specs for your Kaby Lake computer (I assume you have Kaby Lake). (I also assume you have Intel i7-7700HQ)

Here's your Intel CPU specs.

https://ark.intel.com/products/97185/Intel-Core-i7-7700HQ-Processor-6M-Cache-up-to-3_80-GHz

If you install 2666, it will probably clock down to 2400......to whatever JEDEC 2400 that is on the SPD chip.

Spec sheets also show HDMI output capped at 60hz while its been shown to allow up to 240hz via HDMI.

I'd be interested in seeing which manufacture is correct.

@Red-Sand

Crucial isn't saying that if you install that 2666 RAM that it will run at 2666. They are simply saying that the part is compatible.

Is this not showing it works?

Even if officially , the max speed supported is 2400Mhz, the Helios 300 can handle flawlessy a 2666Mhz : why am I saying that?

just because my Helios 300 g-3 572 came out of the box with a single 16 Gb 2666 Kingston ram stick as shown in the following screenshot. it's actually working at 1333Mhz on single channel and not at 1200 as a single 2400 Mhz would work, so no clocking down here!

@Red-Sand and @geekromi

Thanks for sharing.

@dighi

Looks like you have some options. It looks like the Crucial memory that @Red-Sand mentioned earlier would be the best all around.

You are welcome

i just want to ask if a 2666mhz ram upgrade is compatible with my Acer Predator Helios 300 (G3-571) 2017 model.... cause i ask acer service what ram speed is compatible upgrade my laptop can support they told me that my unit can only support 2400mhz but when i checked the crucial compatibility scan it recommends to use 2666mhz ram instead of 2400mhz that acer told me..... so i at lost at the moment what to use for upgrading my laptop.......

woofie 7th gen and ryzen only support 2400 only 8th gen and up support 2666 i recommend either hyperx if you want the best or vengeance dual channel kits either 2x8 or 2x16 i dont recommend crucial its cheap budget ram and they are liars when it comes to compatibility but its up to you and your own budget the supported ram by your cpu its on the intel website specs also some manufacturers might lock the speeds lower if they want to good luck

PS: this thread has 2 years old next time please open your own

so i can use that 2666mhz ram of hyperx like red-sand/hotel hero said here? or stick with the 2400mhz hyperx....

xapim · July 2020

woofie as i already stated 7th gen and ryzen mobile only support 2400 only 8th gen and up support 2666 so buy the ram according to the cpu you have check the intel specs for it
