What DDR5 to buy June 14 2023

The best memory chips are.
Hynix 16Gb A-die: Speeds of 8000Mbps and higher are possible if your CPU/mobo are good enough. Similar timings to 16Gb M-die

Hynix 16Gb M-die: Tends to max out between 7200 and 7600Mbps similar timings to 16Gb A-die

Hynix 24Gb M-die: Even higher clocking than 16Gb A-die. Slightly looser timings

2x16GB ===============================================

Warning if you see a memory kit with a spec like: 6400 36-46-46-100 @ 1.4V it's almost certainly using cut down 24Gb Micron ICs which don't OC very well so don't buy it unless it's really cheap. Corsair seems to have a lot of these high speed loose Micron kits.

TEAMGROUP T-Create Classic 32 GB (2 x 16 GB) DDR5-5600 CL46 Memory (CTCCD532G5600HC46DC01) - PCPartPicker
//should always be Hynix 16Gb A-die. Manually tuning this is way more cost effective than buying high speed (7200+) XMP kits and hoping that they work. Great for both AMD and intel. The stock performance kinda sucks because it's just JEDEC spec.

Kingston FURY Beast 32 GB (2 x 16 GB) DDR5-6000 CL40 Memory (RFBB5-60C40K2/32) - PCPartPicker
//should be Hynix most of the time but can also be Samsung.

G.Skill Ripjaws S5 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory (F5-6000J3040F16GX2-RS5K) - PCPartPicker
//Great for Ryzen if you just want to turn on EXPO/XMP(AM5 boards are able to read XMP)

G.Skill Flare X5 32 GB (2 x 16 GB) DDR5-6000 CL32 Memory (F5-6000J3238F16GX2-FX5) - PCPartPicker
//Great for Ryzen if you just want to turn on EXPO/XMP(AM5 boards are able to read XMP)

PROXMEM KERBEROS 32 GB (2 x 16 GB) DDR5-6400 CL38 Memory (PGD5U64A38XX7-K0WC) - PCPartPicker
// Another Hynix based option. Will need an underclock on Ryzen.

OLOy Blade RGB 32 GB (2 x 16 GB) DDR5-6000 CL32 Memory (ND5U1660320BRKDE) - PCPartPicker
// Another Hynix based option.

Corsair Vengeance 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory (CMK32GX5M2B6000C30) - PCPartPicker
// Another Hynix based option.

Patriot Venom RGB 32 GB (2 x 16 GB) DDR5-6200 CL40 Memory (PVVR532G620C40K) - PCPartPicker
//should be Hynix

GeIL Polaris RGB 32 GB (2 x 16 GB) DDR5-6400 CL38 Memory (GOSG532GB6400C38ADC) - PCPartPicker
// Another Hynix option

TEAMGROUP T-Force Delta RGB 32 GB (2 x 16 GB) DDR5-6800 CL34 Memory (FF4D532G6800HC34BDC01) - PCPartPicker
//Highest XMP speed I'd expect to work on all 13th gen chips. A lot of 12th gen won't run it.

I don't recommend 7200 or higher rated kits because the stability is too RNG.

2x24GB ==============================================

G.Skill Ripjaws S5 48 GB (2 x 24 GB) DDR5-6000 CL40 Memory (F5-6000J4048F24GX2-RS5K) - PCPartPicker
// Can be 24Gb Micron so don't expect it to overclock much but at least it's not expensive

G.Skill Trident Z5 RGB 48 GB (2 x 24 GB) DDR5-7200 CL36 Memory (F5-7200J3646F24GX2-TZ5RK) - PCPartPicker
// Has to be Hynix 24Gb M-die. Great for hitting very high mem clocks on intel

2x32GB ===============================================

TEAMGROUP T-Create Classic 64 GB (2 x 32 GB) DDR5-5600 CL46 Memory (CTCCD564G5600HC46DC01) - PCPartPicker
// Should always be Hynix. So a cost effective option if you overclock it.

// Hynix with a strong profile for both Ryzen and intel

Corsair Vengeance 64 GB (2 x 32 GB) DDR5-6600 CL32 Memory (CMK64GX5M2B6600C32) - PCPartPicker
// strong XMP for intel 13th gen that shouldn't cause stability problems

2x48GB ===============================================

G.Skill Ripjaws S5 96 GB (2 x 48 GB) DDR5-5600 CL40 Memory (F5-5600J4040D48GX2-RS5K) - PCPartPicker
//Should be Hynix 24Gb M-die. Might also be Micron.

G.Skill Trident Z RGB 96 GB (2 x 48 GB) DDR5-6400 CL32 Memory (F5-6400J3239F48GX2-TZ5RK) - PCPartPicker
// has to be Hynix 24Gb M-die. Should be a strong overclocker. Might also work at 6000 on Ryzen.

I have 0 experience with quad rank DDR5 setups(4x32 and 4x48GB) and don't recommend them since they put way too much load on the memory controller.
