Ram overclocking for dummy

[Anjani]

So basically I had single stick Adata Gammix d30 16gb ddr4 ram. I cannot purchase another 16 gb ddr4 ram, as I didn't had the budget and also I have deepcool assassin 3, d30 gammix height would have created problem in closing side panel of case..

So I have corsair vengeance lpx 8gb 3200mhz ram and adata Gammix xpg d30 16gb  3200 mhz. I know they will run in flex mode, meaning until 16gb they will run in dual channel and another 8gb of 24gb will run in single channel. I don't have issue with it. After installing the second stick, the game performance did significantly improved but.. The timings of both ram sticks are different.. Is there any way I can match the timings of corsair vengeance lpx 8gb to that of adata xpg gammix d30 16gb.. I am extremely new, I don't know shit about ram overclocking.. Only I know that ram timings are important...

Ram overclocking is VERY time consuming (I am talking weeks of testing) also there is no guarantee that both chips can run at same timings. In your case I personally wouldnt bother trying to set timings or overclocking but if you want to there is only guide you can follow:

How big is the difference in performance in 18-19-20-16 and 22-23-24-16... Also corsair vengeance lpx 8gb 3200mhz ram advertised 18-18-36.. I checked it online so why it is running at 22-23-24-16

It’s running 16-20-20-38, not any of the numbers you have above. The memory tab is showing the current timings and speed of all RAM in the system.
 

The SPD tab shows what each channels defaults are. 
 

Also, agreed. RAM overclocking is not simple, with lots of room for error… pun intended. RAM instability is really hard to diagnose, and it never actually seems like it would be RAM that is causing the issue. Anything from really weird crashes and bugs to full on data corruption. Don’t try and manually OC RAM unless your ok with losing all the data on your PC and you have a solid week to dedicate to dialing in settings and testing.

From what you have written, I can infer that these are the timings in spd.. Without enabling xmp (1066mhz)..but when I enable xmp the frequency and timings are changed.. Should I really be concerned about it.. Or the Main thing is the memory tab. Also what is jdec17, jdec 18.. Why there are 4 tabs for cas latency whereas from what I know cas latency is cl+trcd+trp... And why the corsair is not running at 18-19-20-16.. As my other ram..

The SPD tab lists what the RAM’s default speeds are (JDEC are the default values, depending on what speed and voltage the chips run at, you can achieve different timings), the SPD tab details those differences. 
 

I think your reading this chart wrong, it goes top to bottom, not side to side. Each vertical column in the SPD tab shows the timing at a different speed. Both sticks show at the far right of the SPD tab that their XMP profile is 16-20-20-38 at 3200MHz at 1.35 volts. Your memory tab is also showing that - the memory tab is reporting what the actual speeds they are current running at is, which confirms they are running at their correct XMP speed (they both have the same XMP speed, and are running at that speed correctly). 
 

The JDEC columns just report what the chips would run at if XMP was not enabled and what timings would be used depending on the MHz used. The chips may have slightly different specifications at the different JDEC speeds, but all we actually care about here is their XMP settings, which are the same, and does match what the memory tab is showing. 
 

Hope that helps.

There is a guide to understand the difference between timings.

You allso need to download taiphoon burner to see wich chips the ram have.

Dang, after reading through a few threads and the link you shared, I feel like I may not be ready to tackle ram OC yet.  I felt pretty good about trying to jump into timing, but feeling a bit less confident now.  Here I thought I was doing something good bumping my Corsair vengeance (3600 MT/s 18-22-22-42) to 1.40v and 3666 and enabling DOCP.  From the sounds of it, my little 66 MT/s bump likely did nothing, and it didn't want to boot at 3800, so I backed it back down.
