How Low Can You Go? Memory Latency Competition - AIDA64

[P4-630]

CPU...….........………..Intel i7 6700K @ 4.3GHz

MOTHERBOARD.....Asus Z170 Pro gaming

 

[DR4G00N]

Here's one for DDR4 with a more typical mobo instead of the glorious MOCF.

That said the board is bad for mem oc even for gigabyte Z270 standards, which is expected for a low end 4 dimm'er. As you can see, once you go beyond 3866 the memory performance tanks although the latency does improve.
Auto timings for secondary's & tertiary's are also terrible, might be able to yield more by setting them all manually but who know's if it'll even boot then.

CPU.......................... Intel i3 7350K @ 5.0GHz 1.375V

MEMORY................. 16GB 2X8GB G.Skill Trident Z F4-4133C19D-16GTZA @ 4000 13-12-12-28 2T 1.6V
MOTHERBOARD….. Gigabyte Z270-Gaming 3

Figured I'd throw my T430s into the mix, seeing as it has some of the fastest (and most overpriced) DDR3 sodimms ever made, so it makes for an interesting data point.

Why it has so low memory bandwidth?

 

[storm-chaser]

Sorry guys I've been neglecting the leaderboards the past few days. So I will get that fixed today at some point.

This is actually a very impressive result... Love me the Athlon 6400+ for that ultra low latency.. not sure what leaderboard to put you on because you are ahead of some of the Ryzen systems and not that far away from my Phenom II result of 49 ns.

Here's a quad channel result. Too bad us quad users don't stand a chance in this contest since dram latency is inherently higher on quad platforms.

Also note, it is the YELLOW jersey in cycling that shows the overall leader. The green jersey has to do with sprints and is not the overall leader.

7960x @ 4.5 ghz, 4x8gb ddr4 3600 cl16.

Go back and re-read the first post, I correctly assigned the green Jersey to the points competition portion of the event, NOT the overall leader.

I hear you on the latency disparity between dual and quad channel. That's why we will eventually have an AIDA64 bandwidth competition. Just gets crazy when you have to tabulate the results from both latency and bandwidth in the same comp...

Please excuse my confusion...

The yellow jersey is awarded....to the rider who is the overall leader of the race so far.

In cycling, the green Jersey represents the winner or current leader in the points classification.

The Green Jersey will be awarded to the rig that dominates the competition across multiple categories.

Isn't the second chart/green chart/points chart determine an overall leader since it combines latency and caches?? Seems so considering it's across multiple(all) categories so a winner there would fall under yellow. Again, apologies if I'm confused...I digress.

Edit: ok..I see where I went wrong. Memory latency determines the winner not the combined result.

Combativity Award*
The combativity award is a prize given to a participant for the most combative overclocker overall.

How does one win this? What is a combative overclocker?

This was won by Phanbouy on Feb 19, 2020 because he substantially improved both his latency and his overclock in one go. Do something exceptional and you might just get it.

I knew you would figure it out eventually.

You technically have the only operational 6400+ rig, so you still win. But I was digging through my archives the other day and came across this little snip from WAY BACK... April 2nd, 2011...

Also found this while I was browsing through some of my benchmarks from the good old days. This was my all out best effort on the Phenom II platform for latency... it doesn't count... but for historical purposes I thought I'd post... wish I still had this ram

Consequently, I got a little nostalgic and had to pull out the old Q9650 rig, still running strong. This is a 100% rock solid overclock...

CPU.......................... Intel Quad Core Q9650 @ 4.275GHz
COOLING................ Thermaltake 120 Extreme

MEMORY................. 4GB DDR3 (2GB x 2) Corsair XMS3 @ 712MHz

This is a 100% stable overclock. However, it gets incredibility tricky to remain stable when you get to the 4.4-4.5 range with this chip, especially on air cooling...

This is my FX4350 rig running at 4.8GHz behind a hyper 212...

Not fast enough on that LGA 775, I got this out of P5B

CPU.......................... Intel Core 2 E8400 @ 4.52GHz
COOLING................ Thermaltake 120 Extreme
MEMORY................. 2x 1GB CellShock CS2221450 1000MHz CL5

Here's going hardcore on E8600 and 4x4GB kit(s) :

CPU.......................... Intel Core 2 E8600 @ 4.33GHz
COOLING................ AIO Alphacool Eisbaer 240
MEMORY................. 4x 4GB Corsair CMX8GX3M2A2000C9 @ 1850MHz CL9
MOTHERBOARD….. Asus P5B (with Vdroop mod)

@storm-chaser Win98 result :
CPU.......................... Intel Core i7 980X @ 4.3GHz
COOLING................ Stock (Intel tower cooler)
MEMORY................. 3x 4GB Corsair CMX8GX3M2A2000C9 @ 1953MHz CL9 (max. 3GB usable because 32-bit OS)
MOTHERBOARD….. Asus Rampage II Extreme (with Vdroop mod)

Also, I should point out that doing it as average puts L1 + L2 at enormous disadvantage, since you get to divide by 4 on everything with L3 cache, while only by three on L2 max. system.

^L4 is as slow as IMC on this, so not exactly usefull.

Platform :
CPU.......................... Intel Core i7 5775C @ 3.6GHz (w/Turbo)
COOLING................ Stock (Intel BOX cooler)

Awesome hardware choices you have there. The 3950X will likely be going in my next rig, I may PM you with about 20 questions later.

EDIT: Have you tried tweaking and tuning the NB speed?

Alright, thanks for the subs... I will be busy well into the evening, so uploading these will be slightly delayed.

Hey, thank you kindly, stranger
Don't mind questions at all, isn't that how we all learn. I may be a little slow, but I clocked a flat 66ns the other day. I'm getting there.

Here I tried just a touch of boost. Maybe update my entry?

 

[storm-chaser]

Okay Guys. I just added a number of subs to the leaderboard and made some modifications as I saw fit. Please tell me if any of your data is missing or moved around.

I think it's all there but it gets difficult working with the data set when you have to keep track of multiple pages.

@agent_x007

I need your AIDA64 result for the windows 98 rig... EDIT: nevermind got it....

 

[freeagent]

I’ll have a run after work today, I should be able to squeeze my 3770K into the top ten for latency.. maybe
