Thinking of a Intel Ram Kit for an X570 build

[BTRY B 529th FA BN]

Hi there. I'm thinking of buying parts a little premature for an Ryzen 3000 rig. How strict are the compatibility rules with Intel Kits running on AMD boards? I don't remember ever buying a compatible kit listed on the EVGA site for my EVGA 760 A1 X58 rig. Same memroy is still being used on a Gigabyte UD7 X58 rev.2.0 board. How are things nowadays?

Per a question I asked a few months ago it doesn’t matter that it’s an intel kit

If I remember correctly the intel part just means its compatibility is guaranteed with intel boards. There is nothing in it to prevent it from working with an AMD board.

It's hit or miss.

With the original Ryzen CPUs, a person was wise to buy memory known to work properly.

The Ryzen refresh (2700X, etc.), memory compatibility was improved quite a bit, but not every module out would work at stated speeds (or not at all in some rare cases). I think people wanting to populate all four DIMM slots were the ones that had to be the most careful with what they selected.

RAM prices have been falling over the last several months, so honestly I would just wait and see what works best with the motherboard you pick out. Motherboard manufacturers don't seem to have their RAM QVL lists published yet for their X570 motherboards. However, if you're pre-ordering the new Ryzen stuff, you will just have to roll the dice on a set and hope for the best (I imagine modules that worked well with B450 / X470 motherboards would be a safer choice).

"Intel kits" have always worked in AMD systems. You just had to hand-tune them. I have DDR4-3733 on my 1800x that is b-die like a lot of other b-die. It wasn't any worse than FlareX kits targeted specifically at AMD machines. Only difference was that I couldn't rely on the pre-set XMP settings at all. FlareX had a good chance of working at the advertised speeds in a Ryzen system.

I’m using a 2x16GB kit of Gskill Samsung B die and it has intel stickers on it and it works fine with no issues or tweaking required in the rig in my sig.

I'm looking for a 3733 CL17 2x8 kit for gaming. I seen a kit on New Egg that was cl17.17.17.37 @ 1.35v 2x8 GB but I'm not sure anything else about it. Do I want single rank, dual rank, etc? I'll probably stick with G.Skill, too. What should I be looking for in a gaming kit? I won't be overclocking the ram and will be running it 1:1

You may want to wait for reviews to decide which RAM to get.

Looks like a slightly better kit than the one I have on my 1800x (mine is um 17-19-19-39?) If you're willing to give it 1.4-1.45v then it'll probably go up to DDR4-4000. I wouldn't know where mine can go since my old Summit Ridge is holding it back.

Also, in general, I would shoot for single-rank 8GB DIMMs if that's where you're going.

Is there a way to know if a stick is single-rank with G.Skill?

There's always Thaiphoon Burner.

Otherwise, 8GB b-die sticks are always single-rank. Or almost always. 8GB e-die is possibly dual-rank. e-die is getting rare though. And e-die wouldn't have timings like that.

edit: G.Skill doesn't have a helpful number code (like Corsair) that can tell you what IC they used on the DIMM. You might be able to tell prying off the heatspreader. But at that point, Thaiphoon Burner is the safer/better way to go.

I don't know how to tell if they are Samsung Die-B plus i heard they stopped making them.

 

[DrMrLordX]

Oh indeed they did stop making b-die. They've moved on to 10y ICs now (b-die is 10x). Those DIMMs apparently go back to Sept 2016 in the first run, when there was still b-die in mass production.

Safe bet is that RAM from that era faster than DDR4-3466 has to be b-die. It's the only stuff that would go that fast. My DDR4-3733 17-19-19-39 is b-die.

Is this kit Single-Rank?

Also found some on Amazon:

Almost guaranteed to be single-rank b-die. It's a slightly higher bin than what I have, which is:

https://www.newegg.com/corsair-16gb-288-pin-ddr4-sdram/p/N82E16820236045

And that's single-rank b-die. Any Corsair DDR4 that says "ver 4.31" is b-die. Gotta look at the back of the DIMM. Newegg lets you do that.

 

[BTRY B 529th FA BN]

Looks like a lot of G.Skill kits are using B-Die. I just have to remind myself I never look at the colors on my ram kit, lol

 

[DrMrLordX]

As long as you are picking something above the range of DDR4-3200 to DDR4-3466, it's almost guaranteed b-die. There are some DDR4-3600 DIMMs out there with high latency that may NOT be b-die, but I haven't found anyone who has run Thaiphoon Burner on them to find out exactly what they are, either. For example:

https://www.newegg.com/corsair-16gb-288-pin-ddr4-sdram/p/N82E16820236538

I have no idea what that is, and I can't see the back of the heatspreader to find out. There are DDR4-3600 CAS/CL19 products similarly-priced:

https://www.newegg.com/p/pl?N=100007611 600521523 601203950 601109764 600006072&Order=PRICE

What ICs do they use? I have no idea.

edit: apparently these DIMMs use a newer Hynix IC (CJR). So not b-die.

 

[BTRY B 529th FA BN]

I found some really good links with descriptions of ICs, Rank, etc.

Not sure if they are 100% accurate but

Ok, so it looks like kits are selling like hot cakes. The Ram I linked and some others I've found have already sold out. Should I wait for better kits to come out or should I jump on the price gouging kits I was looking at that jumped 150+ dollars?

If prices went up by that much, you might want to consider some Samsung M-die, depending on what are your clockspeed expectations. I heard the basic (mostly unbinned) M-die DIMMS available right now can hit DDR4-3333 pretty easily on Pinnacle Ridge in a 2x32GB configuration. Of course I'm talking about these:

[BTRY B 529th FA BN]

I've found some B-Die 4133 C19 Single Rank on the QVL list for the motherboard I chose. Does that seem like a good kit? C19 seems fairly high when 4400 kits are doing C19

 

[DrMrLordX]

I wouldn't worry about the timings too much. It just means you're gonna hit a clockspeed wall on those things before the 4400-4600 kits. Aim for DDR4-3733 with tightest timings. Is that kit specced to run at 1.4 or 1.45v?

It's spec'd at 1.35v

Any kit I pick up I'm aiming for 3733 with C17.17.17 or below. The main goal is to keep a 1:1 ratio with the IF for the lowest raw memory latency. According to AMD 3733 with C17 will return 67ns. I have no idea how they got that number but the lower the better, imo.

So should I get a fast kit like the 4133 and tighten the timings at 3733 or should I get a kit around 3200-3600 and push for 3733 c17? I like the option to play with higher frequencies but I could save money going with a lower frequency. The average difference is about $50 in savings.

 

[DrMrLordX]

1.35v huh

I run my DDR4-3733 kit @ 1.42v and have done so since 2017 or so. Personally I will not go past 1.45v on a 1.35v kit. How far you go is up to you.

I would say, get the fast kit, reduce clocks, and then fight for timings. You can probably do better than CAS/CL17. Aim for 14-16, see what you can get. I got my DDR4-3733 CAS/CL 17 running DDR4-3466 CAS/CL 14 pretty easily until UEFI updates ruined everything. The DIMMs were certainly capable.

 

[BTRY B 529th FA BN]

This morning I checked some items I had on a wish list and they were all sold out, I checked my wish list at Amazon and it said there were 7 left. I did a dry run on Amazon to see what would show up with the 4133 kit and it said it was the last one, ooof. I double checked and opened up another tab with the same item and it said they were no longer available. The 4133 kit should arrive on the 19th so it looks like that will be the kit for my X570 setup, it's just gonna be a while before I pick up a chip. I might go with a 3600X for the meantime till the 3950X comes in.

Are there guidelines to follow with DRAM voltages? Is 1.35v not a good thing with that kit?

 

[DrMrLordX]

Only hard-and-fast rule is that 1.5v is the most you should ever give it without LN2 or similar. I try not to go past 1.45v on benchmark runs. As long as it has decent heatspreaders and gets some airflow, you are fine.
