    Ram Upgrade on Asus Rog G15 (Ryzen 9 5900HX, RTX 3070)

    Hey guys,

    After not being amazed by the performance on this laptop (coming from a HP Omen, i7 9750H and RTX 2070 Max Q), specially on Warzone, I found out that a youtuber says that the problem lays on the RAM sticks, he made a test and the differences were more than 20 FPS so naturally im looking to upgrade.

    In my search I came to a Kingston Hyperx 3200Mhz ram kit at 1.2V, but I also found an Apacer Nox running at 1.35V, so I was thinking if this kit could give me problems as I have never tried a higher voltage Ram or if its worth the extra $$.

    Any other recomendation would be useful,

    Thanks !

    Hi Bro! I can nothing say about Nox, but i am using Kingston Hyperx Impact 2x32gb (HX429S17IB/32) 2933Mhz 1.2V. Memory has timings 17-19-19 in XMP profile, but working as 18-19-19 in JEDEC profile. Because Asus didn't make support XMP in BIOS and i think not make ever. We are customers for Asus are free beta testers team. By this reason - no sense use memory with XMP profiles. Also i tested Crucial Ballistix 2x32gb (BL2K32G32C16S4B) 3200Mhz (16-18-18) 1.35V on this laptop working as 2666Mhz CL19 (19-20-20) with 1.2V in JEDEC profile. Apacer Nox with 1.35V should be working similar as Crucial Ballistix. You will get lower frequency with 1.2V because you can't use 1.35V on this laptop as i am say before - no XMP support with overclocking options.

    I don't play in Warzone, but exist opinion what for "fast" online games better use memory with lower timings. For "heavy" games such like Cyberpunk 2077 recommended using memory with higher frequency. The ideal variant for gaming you need min timings and max frequency. If Asus make XMP support in BIOS or you find someone who make custom BIOS for you, i think best choice will be Crucial Ballistix 16T is faster laptop DDR4 memory for today and cost lower than Hyperx Impact.

    Don't buy 1.35v XMP RAM for Ryzen

    Don't do it. Ryzen RAM runs only at 1.2v JEDEC. The 1.35v requires XMP, which requires Intel. If it says 1.35v or XMP, don't buy it. That 3200 1.35v RAM will only run at 2666 on AMD so be careful.

    Best you can do is make sure you are running 1.2v, dual rank, dual channel, 3200MHZ, Micron or Samsung (not Hynix), CL22-22-22@1.2v or CL20-22-22@1.2v, tRFC 560 (or less), bought in a matched pair kit. Unfortunately the retailer won't give you these specs so grab the model number and head to the manufacturers site. Generally 2x16GB RAM kits are more likely to meet the dual rank requirement. If the chip says 1RX16 on it then you don't want it. Opt for 1RX8 or 2RX8.

    Test your RAM before and after with ZenTimings and verify Frequency (3200), tRFC (560 or lower, 350ns or lower), CL22-22-22 (or lower).

    An example of a good spec sheet is Kingston Fury KF432S20IB1K2/32. Note 2Rx8, CL20-22-22@1.2v, tRFC 350ns.

    This stuff is hard to figure out. I've been studying it but I'm still no expert. For example, is there really much difference between 1RX8 and 2RX8? Not sure, but 1RX16 is bad and that's what OEMs are shipping.

    Its not ASUS, its AMD. AMD supports JEDEC 1.2v standard speeds. Intel supports JEDEC 1.2v and XMP 1.35v. The problem is faster speeds can sometimes produce poor performance depending on which Intel CPU you get. It's all very complicated.

    Now ASUS chose to put junk 1RX16 RAM into their systems instead of 1RX8 or 2RX8, so you can blame them for that, but you can't blame them for only operating at 1.2v.

    You wrote complete nonsense!

    I don't know whether on purpose, or from a "very big mind". But i also tested Crucial Ballistix 2x32gb (BL2K32G32C16S4B) on

    - ASUS ROG Strix SCAR 17 G732LV with Intel Core i7 10875H
    - ASUS ROG Strix G G731GW with Intel Core i7 9750H

    On both laptops memory didn't work with XMP. But, for G731GW exist unlocked custom BIOS where you can manage timings and voltage and possible to enable XMP. Unfortunately notebook working unstable with XMP. I think what guy who modify bios firmware did something wrong.

    About AMD starting with Ryzen 2000x series xmp supported on few models. But starting with Ryzen 3000x and higher all CPUs has full support of XMP.

    Therefore, all claims are only to the a##holes from the asus.

    OP, I would run Aida64 or similar and see what exactly is in your laptop first and work from there. This post might be useful for RAM upgrade options, it dealt with previous laptop 4000 series cpu's but may provide some type of baseline for 5000 H series (ymmv).

    My expierience from owning two 4800h laptops is that 1.2v@3200 will run correctly. Sodimms 1.35v@3200 will run @2666 (ymmv)

    SO-DIMMs @ 1.35v also have SPD Table written on them, making them run at different speeds, timings and volts than with XMP. So DDR4 3200MHz CL16 1.35v will work on our laptops according to the memory's SPD table, often 2667MHz CL19 1.2v - not a good buy.

    Best is to buy 1.2v SO-DIMM RAM, 3200MHz, and 2 sticks that have RAM modules on both sides, Ryzen 5000 series CPUs are gimped with "single sided" sticks.
    Buying 1.35v RAM will be a lottery, you won't find the SPD table/timings info easily, maybe from reviews.

    I upgraded bro's PC two weeks ago, added 2x8GB DDR4 3600MHz CL16-18-18 1.35v, mobo sets it according to JEDEC/SPD table, and it was 2667MHz... just needed to enable the XMP Profile in BIOS

    XMP and SPD Table are written on the RAM sticks in binary format, not on stickers
