How Low Can You Go? Memory Latency Competition - AIDA64

There's something funky with this board just not wanting me to run the primary timings too low. It will run CL10 with stupid tight secondaries but the moment I ask for CL9 it hard locks. Wanted to see the little guy go under 50ns, but oh well.

CPU..........................AMD A10-6800K @ 4.8GHz
COOLING................NZXT Respire T20 Air Cooling
MEMORY.................2x4GB G.Skill Ripjaws X DDR3-2133 (10-10-10-20 1T)
MOTHERBOARD…..ASUS A85XM-A

Two separate DDR4 kits of: PNY 8GBF1X08LFHH35-12-K & PNY 8GBF1X08QFHH36-135-K
32GB with all slots populated.

i3-6100 4186MHz 1.184v DDR4 1.35v 2866MHz 13-12-12-39-258-1T

Best I'm able to do so far I can get 13-11-11-39-258-1T to post, but it isn't stable. I think it's something cooling related, but it's hard to tell for certain if I bumped up the DDR4 voltage it might be stable though or enough to benchmark AIDA64 it might anyway didn't try, but Firefox Nightly was crashing and left and right when I lowered the tRCD/tRP by 1. I didn't have any luck figuring out how to stabilize it though I didn't try to bump up the DRAM voltage was trying to keep that stock for now anyway. Interestingly AIDA64 is claiming it's Samsung chips on the 2x16GB G.SKILL RIPJAW V DDR4 3200MHz 16-18-18-38 kits. I don't know why that is I was under the impression they were SK hynix chips in the past, but never tried to physically check underneath the heatspreaders. I mean if they are in fact Samsung's that a unexpected positive I suppose if I were to put more voltage to them. I guess 45.9ns isn't too shabby for a i3 though with cheap AsRock pro4s motherboard it cracked the top 20 on here apparently.

Got it down to 44.1 ns overclocked the CPU and DDR4 a bit further to 2900MHz with the same primary times 13-12-12-32-CR1 only needed .025mv more CPU voltage 1.216v total as well to get it stable enough boot and bench. I thinking if I replaced the stock fan on my Sunbeam Core Contact Freezer with a Noctua NF-P12 redux-1700 PWM, High Performance Cooling Fan, 4-Pin, 1700 RPM I could get better cooling efficiency out of it overall and possibly push another 50-100MHz out of the CPU/RAM. I could even re-purpose the older can blow some of the heat upward and out of the case quick as well. I could defiantly zip tie it underneath if I'm not mistaken it's not a show case side windows so I don't care how ghetto it looks on the inside lol long as it's functional.

How low can I go?

I can go Mariana Trench low. I can go florescent rock at the bottom of Mariana Trench low. I can go layer of green slime underneath that damn rock - low. :laugh:

Damn that's impressive. Very good result. Actually, if the competition was still going you would be #1 by a sizable margin. Mariana Trench low? That's more like center of the earth low!

I don't know what type of memory you have there but I want some of it.

Btw, anyone know if Dr4goon(the guy who won the competition) is Luumi? I just sense that he is Luumi for some reason, i don't know why.

would be cool if it said Where did you start from

originally 2different corsair vengeance 2133 c16 hynix m die i believe ... still working on the timings sorta got to this point and got over waiting for memtestpro to reach 100%

I am quite late. I consistently get 64.1ns or 64.0ns , while L3 cache is all over the place and MEM write is usually ~55,000 sometimes getting 58,000. 3760mhz 16-18-18-38-58 @ 1.41V on some EVGA low end memory.

Why is the Memory Write on Ryzen 3600's so much lower than the higher core count parts?

This is an old screenshot but I wanted to post here anyways as this was my best effort on latency on the Phenom II platform.



After some further tinkering and tweaking I was able to get it down to a sub 34ns result...

Pretty good, now let us see the actual benchmark run.

Not even sure if I did a read and write test with this as I was focused on purely on lowest possible latency results, to the exception of all other benchmarks.

My NAS is up north and I'm in the city for a few weeks, so once I go back there I can check my archives for you and will post it here if I can find it.

@Arctucas
So I was not able to find anything else in relation to this run. The 33.9ns run was my last and best run to date with this equipment. Anything higher than 3122MHz on the CPU NB and it would not post...
The actual "run" is simply done by running the aida64 latency test, so the screenshot is the only result you get after the test has run... In other words, I didn't do the complete cache and memory benchmark test here, just latency ONLY and that was the point.

Are you laughing because my DDR3 Phenom II system from 2012 is making your high-tech high-dollar 2020 DDR4 system sweat bullets in the memory latency department?

Cheers boys!

:toast:

'high dollar'
'z390'
Please, get a job buddy. And I own two X299 systems, that z390 '''high''' dollar system is merely a toy now. Cute how you think the 2ns difference does anything with your puny memory bandwidth.

Golly man, how low can you go?

Obviously, not low enough.

Not as low as your terrible insults, unfortunately

Relax, take a deep breath, we are all just friends here at the end of the day! Besides, I thought you thought I was laughing with you, not at you. You know, seeing as how you laugh at all my posts when nobody else does.
