Silicon Lottery or (more likely) lack of understanding RE Memory Benchmarks


Recommended Posts

Hello everybody!

First time posting to the forum, indeed it is my first time viewing the forum.  Ive been using the Engineer version of Aida64 (registered) for about 3 months now, and overall Im impressed with the software.  Its nice to just throw together a few different benchmarks and have them run how and when I want in the order I want.  I was doing all this with macros before ;)

Ive recently gotten back into building PCs, took a long hiatus back in the late 90s my last system having been assembled was a 440BX based chipset on an Abit motherboard, both of which no longer exist at least in a meaningful way lol.  I was an OC neophyte back then, as I am now, although I do enjoy the hobby/sport(?)

I decided to wade into the dark and murky waters of RAM OCing, and went down that rabbit hole for a few weeks.  Long story short, I bought 2 x 16GB sticks of G.Skill 3600mhz XMP mem.  Stock timings sucked at 19-20-20-40-500 but I didnt know or care much about timings at the point I bought and assembled the system and so didnt realize their huge impact (relatively speaking) on ram performance.

I was able to get them to post at 4000mhz 17-22-22-36-485 and ran that for a few months, then last night got the idea to try and tweak them some more, thinking maybe all these on off cycles might have trained them to do better (i dont know if that logic is incorrect or not in regards to training, but its how I justified another sweaty night of swearing out loud and smashing keys to my wife)

Im now resting at 4000mhz 16-22-22-40-500 but I can feel they have more to give in the timings department.  Frankly, im already amazed at how well these Hynix CJR chips are doing on the OC.  My question is basically, Aida shows me as being first place in Latency, and near top tier in every memory bench, with only quad channel or server boards (mostly) beating me.  Are these results typical for these chips and my rig?  What can I do to push it further if anybody has any recommendations?  And am I correct in feeling a sense of accomplishment at being in the top spot for latency, or is my joy tragically misplaced?

Thanks a lot guys, and to the Devs, great product and I will continue to use and support you!

Forgot to include OCd mem speed (4000) :)

These are respectful numbers indeed.  Can they be better?  I don't know, since we're not skilled in OC here at FinalWire :) Others may be able to chime in and give you more meaningful feedback on the OC achievements.

AIDA64 results are quite decent, they will show the averages pretty accurately, what is happening is that you're pairing a low end cpu with a very high end memory (4000mhz) and you will indeed find excellent results, the problem with dual channel memory is that you are on the limit of what is achievable with dual channel.

You will see very often 100GBPS + results with Quad Channel 3400+ Memory. So don't compare yourself against "Stock quad memory".
You're comparing extreme OC Dual Channel vs "Regular" Quad.
But your results are pretty good and I didn't know it was possible to OC the memory on the 9400F 
I've been using exclusively X79, X99 and X299 for far too long so I was unaware of that.
