I have different sticks of ram and I'm fine

[Noam123]

my specs:

gigabyte h270-gaming 3 motherboard

core i7-7700

F4-2666C19S-16GIS
F4-2666C19S-16GIS
 

those ram sticks are almost the exact model but with different cl and speeds and I'm fine actually now i think of it I didn't get any blue screen in the all 3 years I used them together exepct two times but it was because of power issues of psu

IIRC, the problem that usually occurs with memory sticks that isn't bought in form of a kit is that RAM manufacturer often revise the models down the road, changing ICs and such on the PCB.

Example :

You can buy the very same exact model later down the road but it may have different ICs.

It may play nice with the existing one, and it may not.

 

But usually the problem that occurs is simply borked XMP/EXPO/DOCP profile, but setting the RAM manually instead of using XMP/EXPO/DOCP usually solves it.

Is there a question involved with this? 

 

Mixed RAM isn't a guarantee that your system will have issues, it's just that it's more likely to have memory issues than a setup with a matched memory config. The issues come with the fact that different memory kits come with different memory ICs (even the same model number can have different ICs on board), and each of those different ICs have a different window of acceptable parameters that are figured out during memory training. Sometimes they overlap and you have two ICs that play nice together, other times you get two that don't and won't even boot in the same system. 

 

With DDR4, especially low speed DDR4 like yours, compatibility is usually pretty good across sticks, it's rare to have a setup where mixed RAM won't boot. It's not impossible, I do own two sticks that will not boot in the same system no matter what I do even though they both work individually, it's just quite uncommon. Issues usually start showing up when you doing stuff that's a bit more exotic, like running 3600MT/s and higher or doing anything with mixed DDR5.

It's all a question of probability. A matched set should almost always work, but it might still have issues. A mismatched set is less likely to work, but it still can, especially when frequencies are lower/timings are higher.

The top issue is lower performance, especially when it comes to XMP, not bluescreening.

I have found a nice deal in micro center for MOBO+CPU+16GB RAM but i need 32GB can't i just buy the exact same model?

You can. But even the same model may have differences (e.g. different ICs) depending on when the particular module was made. There's simply no guarantee it'll work at full speed, but it might.

 

Does the deal come with 2x8 GB or 1x16 GB? Are we talking DDR4 or DDR5?

We're talking DDR5. The bundle comes with the G.Skill Flare X5 1X16 GB (1 x 16 GB) DDR5-6000 CL36 (F5-6000J3636F16GX1-FX5).

I wanna buy same exact module again so from 1X16 it's 2X16

the exact same wont guarantee the sane chip but that lowbin gskill is probably some samsung or micron based garbage so any 5600 or 6000 non 1.25v kit will get you the same or an ic with similar characteristics

ngl i wouldnt bother with the microcenter bundle anyways

 

https://pcpartpicker.com/list/g6zMQd

You can just get a 180$ 9600x or newegg 155$ 7500f alongside a board that doesnt completely suck vrms wise for 120$ and some actually decent ram thats also matching, theres also the b650-s wifi at 130$ if you want an atx board instead of an matx board for whatever reason

 

It may not be as cheap but atleast the board wont have total dogshit vrms and the ram matches so no worries about compatibility not to mention being hynix based and not dogshit micron/samsung based so you can just follow buildzoids easy hynix timings for an easy performance boost and simply clock them to 8000+ or whatevers needed whenever you decide to upgrade the cpu

And already only the motherboard and the cpu together are 50$ more not even including RAM which's easily 80 to 120 bucks more

Link to bundle?

 

If the board is somehow not pure dogshit vrms wise then just buy whatever non 1.25v 6000 high cl bin and youll get a similar ic
