Ram Suggestion Requested - Page 2

post #11 of 16
Overclocking your ram will have very little to no effect on your machine for what you are using it for. Frequency is also not the only thing you need to look at while overclocking ram. Even if you manage to get the frequency up, if the timings go up as well, you may get worse performance. The trick is getting the frequency high and timings low. Unfortunately this also will end up causing instability while overclocking the cpu. Adding extra voltage to the ram can help but there is a limit to what the cpu will take when it comes to that as well. I recently burned up 2 of my chips pushing them as far as they could go and it did nothing for my gaming.

If it were me, Id stick with what you have. There will be no noticeable benefit to overclocked ram, nor would purchasing higher speed help much. Not worth the cost if you ask me. Put the effort into overclocking the cpu for better performance.

Stock CPU, ddr4-3000 ram
OC Genie CPU (4.5), ddr4-3000 ram
Manual 4.6Ghz OC, ddr4-3000 ram

NovaBench - Benchmark
Prime95 - Max Temps under load.

Any other suggestions for basic testing, since I happen to have some gear to change around. I'm not trying to test/bench a whole weekend, but I'm willing to add a few apps to these 2, if the resulting info/data would be useful to anyone. The point is to deliver possibly useful info, for anyone else OCing similar hardware.

Do post those results. Regarding basic testing, from the little i´ve done so far i used Aida64 and OCCT 4.4.2. Never used Prime, but from some reading i´ve done so far here, there´s at least one version that
stresses the CPU too much.

When i stress test my CPU with different settings, usually post the data in this forum, might help someone like it helped me when i was researching components.

When you say overclocking the ram, do you mean enabling XMP or do you mean manually tweaking the variables?

My goal is to run XMP and speed up memory transfers with faster ram, not to manually OC the ram sticks.

About 1000 years ago, I was big into Overclocking. Then it was much more complicated and on multiplier locked chips, it got real hairy since you were left with only the bus speeds to tweak. I tweaked things to within an inch of their lives. Amusing note, I built one with something like 500 combined CFM in a case. It sounded like the damn thing was about to launch. Cooled reasonable well though. smile.gif

What I learned then was that the added speed wasn't worth the major hassle OCing was back then and it simply ate chips faster. Now, I want to do something more moderate. Something along the lines of bumping up an i5-7600K from 3.8Ghz to 4.6Ghz, Air Cooled, DDR4-3000, SSD drive, etc., with some reasonably silent fans for air flow. I get a noticeable bump in performance, but I don't have to worry about liquid cooled, watching temps like a hawk, etc. My goal is lazy OC, but I wanted to know, from the experts here, what I'm getting into and what really matters these days.

NoveBench results to date:
Lower score is stock CPU speed (3.8Ghz), higher score is OC Genie 1-click OC to 4.5 Ghz

If you just enable XMP it will set your ram at the speed you purchased it at, so 2133. If you dont set it, it will go to default speed. Im not sure what this is for yours as I don't use DDR4. With XMP enabled, you can choose a higher speed, such as the 3000 you are shooting for, but it will auto adjust the timings as well, thus not really making it any faster, if at all. If you really want more out of the ram, you will have to get down and dirty with the overclock which just isn't worth it for what you will do with it.

Luckily, the ddr4-3000 wasn't very expensive. In my case, I'll likely just set XMP to 3000 and leave it.
As you correctly surmised, I'm not trying to tweak the nickels, just a reasonable boost, with basic effort.

Thank you for the insights. I appreciate you taking a moment to share expertise.

DDR4-3000 ram arriving today. I'll run some benchmarks tonight w/ 2133 and CPU stock/OC Genie.
Then repeat with the DDR4-3000, then post results here.

Sorry for the delay in following up here. We're rolling out a new software package at my job and it's had me hopping.

Bechmarks used:
Heaven
NovaBench

Difference in benchmarks 2133 ram vs. 3000 XMP ram.
Essentially, no statically significant difference between the 2 ram types. Benchmarks were within 1-3% of each other. Each test was run 2-3 times.


i5-7600K Stock vs. 4.5Ghz
This made more of an impact. Both benchmarks were 10-15% higher with the higher clock speed. Each benchmark was run 2-3 times.
