Question Windows showing more RAM than I think I have.

[JuniorGs]

My PC had a 8 gb 2400Mhz Crucial BallistiX module and now I got a HyperX Fury 2666Mhz also 8gb (product code is
HX426C16FB2/8) but Windows shows that this modules is 16 GB, it shows a total of 24gb of physical mem, also cpu-z and occt are also showing 24gb total, and my BIOS shows the same, and both are 2400Mhz on the BIOS, my mobo is a gygabite a320m s2h.
What could possibly be happening? PS: English is not my first lang.

Can you show the SPD tab in CPU-Z for both RAM sticks ?

Guess you got lucky and got double the size you asked for.

(product code is

This is taken from the sticker on the module?

Yes, its taken from the module, I downloaded aida64 and it shows that the hyperX module has a different code and its indeed a 16gb module.

Your were double Lucky

1. Received a stick with double the amount of RAM you paid for
2. That your 2 different RAM sticks decided to run together in dual channel even they are completely different models

To the OP, your DIMMS are also defaulted to the speed of the 8gb stick (2400mhz). Ryzen loves fast ram, so although you have more ram, it won't benefit you in games, where 2933mhz ram would give you a nice little boost in FPS.

Maybe, but think he changed from single to dualchannel and the boost that will give. Yes 2933 or 3200mhz would of course be nice, but 2400mhz will work fine.

Yep, true on the dual channel too. It will give 10-15% boost, task dependant, but very much so for gaming.

Playing elden ring I noticed less stuttering, before when it was just 8gb it had some stutter when loading too many enemies on screen on open world location, now its much smoother, I guess before with only 8 gb it was using virtual memory which is slower, since windows uses up to 3gb, i had only 5 fir the game, and I work with digital sculpting and I noticed a lot of improvement, the software the I work with, zBrush, eats quite a lot of ram because it works with millions of polygonson screen, normally up to 40-50 millions.

Is it worth overclocking ?

 

[Roland Of Gilead]

If your familiar with the bios, then yes, it can be worth it. For example, on my 1600x/B350 rig, I have my bog standard corsair 2400mhz DIMMs OC'ed to 2733mhz. Whilst not the max boost you can get with faster ram (2933/3000/3200 etc) it gives about a 5-10% boost. This was with an increase of ram voltage from 1.2v to 1.25. Timings remain the same.

However, it all depends on what options your mobo has, the IMC of the CPU. Test it in straps of 133 mhz, or whatever options your mobo allows. Then test with memtest86+ at each new setting ensuring it passes 4 tests with no errors.

Also, keep in mind your particular ram may not overclock well. Add into the mix your other 16gb dimm with different settings. It may be tricky to get them both to work at faster speeds. But, it's possible.

A voltage of 1.35V is perfectly fine for ram so if you need that just use it and maybe playing with other voltages like the SoC voltage might help to, but from what i know don't go over 1.2V with the SoC and 1.15 should be really the max safe.

Well, after 1.25 (and regardless of how much further I went), they weren't stable. 2733mhz seems to be the max for my set. Believe my I tried further, but no joy So at 1.25 and 2733, for generic DIMMs, that's fine for me.

 

[kerberos_20]

only 16GB ram is on dual channel, rest 8GB is single channel

I'm perfectly aware of that, but thanks for pointing that out, JuniorGs might want to know.

 

[JuniorGs]

So its kinda running on something similar as intel's flex mode?

 

[Vic 40]

Yes exactly.
