Great review thank you. Question - why would having brand silk screen on the ICs is a negative?

 

[b1k3rdude]

But how stable over time is anything over DDR5-6000 on AMD..?

 

[docnorth]

Holy s##t, I didn't even realize the 32GB kit was 480 usd (!!) when reviewed. Less than 15 months later it did cost me 136€. Both kits (32 and 64GB) look still like (very) good choices if the user is not very interested about overclocking.
Thanks @ir_cow.

I'm asking the same question.

 

[MKRonin]

Did you try Thaiphoon Burner to confirm whether it is Hynix M-die or A-die?

That wouldn't tell me and it wasn't very accurate for DDR4 either from my experience. I also don't trust Thaiphoon burner not to wipe my SPD data. Supposedly fixed now, but that was a nasty bug.

Great review thank you. Question - why would having brand silk screen on the ICs is a negative?

The main reason is to keep these companies honest. You get one sample for review and retail is a whole different one. However, in this instance G.SKILL doesn't do that and I've noticed they EOL SKUs when switching stuff. Some companies have been caught red handing doing this stuff in the past.

Secondly, if you are into overclocking, it is much easier to setup your timings and voltages from the get go if you know what to expect.

That's the two major things and neither changes the review outcome. Overclocking is not guaranteed.

But how stable over time is anything over DDR5-6000 on AMD..?

It will vary per CPU. Mine can do 6400 in 1:1, but not all of them can. As for overclocking, well once you enter the 2:1 ratio domain, it kinda defeats the purpose of having this memory kit as you will get major latency penalties.

Thanks for the review. I have never had any issues with their ram.

I just upgraded to a 7800X3D and my Corsair 64GB kit does the EXPO 6400 no problems.

@ir_cow What is this "RAM Test" that is being used for stability testing? Possible to share where we can get it from?

I use Karhu software. It's not free though. https://www.karhusoftware.com/ramtest/#introduction

Good free alternative is memtest5. I just found that Karhu picks up errors faster. No preference otherwise. They both get the job done.

You better use this pricing quick. The DRAM gang has announced prise increase each Q of 2024 about 20%. Where the one does the price jump, all would joint it soon.

Great, thank you for the links.

Somewhat related. What's your method for removing the heatspreader? Isopropyl alcohol and a blade along the sides then top?

Also, thank you for your work. I have the black version of this kit.

No need for all of that, we are well past the DDR2 days of glued heat spreaders.

Hair dryer for 30 seconds, pick a side (with ICs) and start to peal. Usually takes a few tugs before it starts to come apart. Once you get a small gap, if needed apply heat inside that gap as you peal some more.

What you don't want to do is a pull them apart while cold. Best case you just ruin the thermal tape. Worst you pull a IC off or transistors.

Some are really easy and its a single round. XPG is the hardest to get apart. G.SKILL is second. Worse care you just replace the thermal tape after you ruin it. I had to for this kit. Really didn't want to come apart on one side.

Thanks for the insight. I'm feeling a bit more confident about the mod I want to do. Have a great weekend!

Interesting that the PMIC was redesigned to be dual sided. I assume it lowers temps... "First gen" variants of this kit are single sided PMIC like other brands.

Still 10 Layer Hsien Jinn PCB's. Shift from almost using Brainpower 10 layer exclusively on DDR4.

Edit: G.SKILL has been relabeling Hynix IC's since DDR2/3 days. Prob a supply chain/purchasing agreement via Hynix. Other brands are doing the same.

 

[bobbybluz]

Did you try Thaiphoon Burner to confirm whether it is Hynix M-die or A-die?

It's A die. That's reflected in the last digit of the part number. I have the same 64GB kit in my Z790 rig. I'm planning on seeing if 96GB (48x2) will work. No complaints from me, performance has been flawless so far.

These G.Skill 6400 CL32-39-39 1.4v 16GB density kits are both HYNIX A/M RNG, but the specific kit here is obviously A die given sticker ID.

More likely to get A die in 2024 if retail clears inventory often, though there could be certain batches of M 16.. depending on supply chain. Both do these timings fairly consistently.

48GB/96GB variants are currently M-die 24GB density. (Completely different from both M/A 16GB).

Advantage to M 24 on G.SKILL end is 1.35V vs 1.4V spec for specific 6400 CL32-39-39 timing.

@ir_cow

slightly off-topic, but I thought you might find this interesting:

I was looking at a 32gb ram kit recently for my laptop and I noticed it say Intel XMP and AMD Expo certified and it even directly says it supports both. thought that was strange, never seen a desktop kit say that. it also ram at 5600, 5200, or 4800, 3 options to prevent issues/compatibility. Crucial brand, but I find all of that very impressive as it seems to be non-existent on desktop kits for some reason.

Hi Thanks for your review

I have just bought this 64GB kit to help me trouble shoot my AMD system issues.

Asus Crosshair X670E Hero / 7950X / Strix 4090 / Be Quiet 1500W PSU / Lian Li Dynamic Evo XL / G.Skill Trident Z5 NEO RGB 64GB DDR5 6000MHz (F5-6000J3040G32GX2-TZ5NR) 2 X 32GBs

I was having terrible stability issues, random restarts, Code 46 with almost every Windows restart etc...sometimes slot 2 RAM would disappear in Task Manager in windows

EXPO on or off made no difference. 4800MT/s or 6000MT/s had the same problems.

My screen would flicker for about 30-60 seconds, and sometimes that would lead to a random restart.

I narrowed down the issues to one of 3 areas: CPU IMC was bad, Motherboard was bad, RAM was the issue.

I popped the RAM in my Mini ITX B650E / 7900X build, and it works flawlessly.....at 6000MT/s

I still had a feeling that the memory was the issue....

So last week in Microcenter I bought this XMP 3.0 kit, just to experiment...

For some reason, everything works flawlessly now once I swapped out the RAM.

My goal was to downclock this kit from 6400MT/s to 6000MT/s and see if that helps, but for some bizarre reason, 6400MT/s worked flawlessly straight out of the gate.

I am now running G Skill F5-6400J3239G32G, 2 X 32GBs, 6400MT/s on the Hero X670E with zero tweaks, apart from enabling DOCP in the BIOS, and changing MCLK=UCLK

One week rock solid, without any issues.

I have 3 comments on the review:

1-
On page 4, showing AIDA XMP readout, why is the ram showing:
Module Size 16 GB (32 banks)
Weren't you testing 2 x 32GBs sticks?

2-
On Page 5, your CPU-Z shows:
Channel #: 4 x 32-bit
Isn't this kit DUAL CHANNEL memory, rather than Quad channel?
My CPU-Z using this kit shows Channel #: 2 x 32-bit

3-
On Page 15, showing AIDA memory and cache screen shot for the overclock on Intel to 6800MT/s, it indeed shows that the memory configuration is QUAD CHANNEL?
I am confused regarding the QUAD CHANNEL thing?
Aren't all the current Intel and AMD consumer platforms all just Dual channel memory?

Many thanks

Not sure if this is a SPD or AIDA64 error for the readout. Everything is correct it seems. Maybe it's just detailing 1 Rank instead of 2?

This just a different version of CPUz is my guess.

Yes it is dual channel. DDR5 is still 64Bit per channel, but is split into two 32bit sub-channels. Intel and AMD both refer to as a single 64Bit connection per channel. I guess it comes down to if you counting by sub channels instead. Lots of debate here. While I would consider this to be "2 channels" per DIMM since they are independent of each other, I'm not sure where the line is between 2x32(sub) and a single 64bit bus per channel.
