  • Community Question: What makes a good motherboard?

Just how BAD is it trying to overclock your cpu with 16 latency ram?

I've heard that to get the best overclocking you want 3200 speed ram, but that you want 14 latency. (or "B" Die). But 14 latency ram looks to straight up cost twice as much as the same speed ram with 16 latency.

How big a difference is it for overclocking Intel?

How big a difference is it for AMD?

For Ryzen, as long as its 3200MHz, latency doesn't matter too much. B-die is much preferred if you try and push past that. Which is into diminishing return territory.

IMHO CL14 is not worth the premium unless you're going for maximum frequency.

The two aren't related. But in games you will see a larger difference in performance based on overall Memory response time. The sweet spot being 3000 or 3200 CL14. Moreso than overclocking a CPU (another reason why it doesn't help when people over focus on ST CPU performance).

On AMD it's even more important. Internal data pathways are based on memory clock speed. So even faster memory with worse CL ratings can see a measurable increase in performance. The end result is both see relatively close amount of uplift from better memory but AMD's increases are slightly higher.

Your question might need some clarification.

Are you referring to how it effects your CPU overclock? It would have negligible affect on how high you can overclock your CPU regardless of brand.

Are you referring to how high you can overclock the memory? Assuming 2x8GB sticks here Samsung B-Die memory will tend to achieve a higher combination of speed/lower latency then the Hynix (M-Die?) memory. This is why kits binned kits for Samsung B-Dies go to 3600CL15 (or faster but with latency penalty) while Hynix goes to 3200CL16 (or faster but at latency penalty).

Are you referring to how it would affect actual performance? I'm going to assume you're referring specifically to gaming here (going to your other posts). Even with that specificity it depends on the work load. Not just in terms of the game but what your trying to achieve in the game (some games like FO4 are more dependent on memory performance). It tends to make a larger impact if you going for high avg fps (to match high refresh displays) and helps alleviate worst case scenarios (so what would be measured with things like min fps, or 1% lows, etc.).

As for your Intel and AMD specific question, It benefits both but relatively a Ryzen system would gain more for gaming going from 3200CL16 to B-Die kits compared to an Intel Coffeelake system. There are lot of factors involved for why this is (some of it isn't clearly explored). Just in terms of setup 3200CL16 kits will just work on Intel CFL systems with Z series boards essentially (they're basically QVLed for Intel) at rated specs with minimal effort (just set XMP) whereas not necessarily for Ryzen systems.

Something you should keep in mind is a lot of the general sentiment regarding B-Dies is that may be rooted in circumstances that do not apply or matter to you. B-Die price differential was not always what it was now. At a time even 3200CL16 carried a heavy premium (whereas now its negligible over the cheapest DDR4) while B-Die kits on top of it weren't much more. Another factor is that pushing the importance of B-Die kits was also important with respect to Ryzen systems (especially Zen) as that represented the optimal (really more favorable) to setup for it.

Well, it looks like it could be samsung b-die, and the price is nice for C14 3200 !

Team Group RAM using Samsung B-Die? That would be... interesting. Price is reasonable.

I’m not sure if this will help or not but I varied the speed of my ram from 2133 to 3333. At the 2133 strap I think the latency defaulted to 15 or 16. The rest were at 14.



This was on my threadripper 1900X. It performs around an 1800X or 2700X.

DIdn't have any issues overclocking my CPU OR RAM on my 1950X, and it's Hynix CL16. 4.2 GHz keeps the bedroom cozy when I'm gaming at night. :)

(note that I can tighten RAM timings quite easily on this board).

There is surprisingly not much information on this on the net, but I was able to stumble across this after a quick google search: https://translate.google.com/translate?sl=fi&tl=en&u=https://www.io-tech.fi/artikkelit/ddr4-muistinopeus-ryzen-2n-suorituskyky/



I believe there is an even more aggressive CL14 3466 version of 'The Stilt's' timing presets available, but this gives you a good idea of what you can expect against the 'baseline 3200 CL16' performance level. It's not the end of the world, but you do stand to gain a solid ~10% in gaming performance it seems.

If the difference between B Die and non B Die is less than $50 I'd probably go with the B Die kits.

Would it work well with Intel or AMD? I see a ram that likes to indicate that it's for one platform or the other.

IMO the extra $50 or $100 is much better spent towards a nicer GPU, Monitor -- just about anything besides faster latency RAM unless you are trying to set records on 3dmark.

Then what would you suggest for either an 8600k or 2600x build? Using a 1060 GTX for 1080p gaming here.

I ran an 8700k at 5GHz on Vcore = 1.37v, AVX2, no reduction for AVX. The RAM was Corsair LPX 3200 with timing of 16-18-18-36, Vdimm = 1.35v. I guess "lax" timing did not interfere with overclocking.

Too late. :p The 3200 14 latency sticks went up from $159 to almost $289. >.<

Looks like one is Red and the other is Grey https://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&N=100007611 50011857 600561668 600546709&Manufactory=11857 . The really high price is a third party seller. Those prices are crazy though, I thought RAM and SSD were on the way down and unaffected by tariffs.

If you don't mind stepping down to 3000 CL15 the Corsair Vengeance LPX (low profile) are priced semi reasonably at $130.

In the first post, OP said he wants to know if he can OC on 3200 with a CL above 14. I think we have established that he can, so he can save some money.
