Question Post your MaxxMem² score

[igor_kavinski]

Thanks to Det0x for using this utility in his benchmarking and thanks to AdamK47 for posting his score, thus making me aware of this utility.

Det0x's score: https://forums.anandtech.com/threads/zen-4-builders-thread.2605910/post-40890534

AdamK47's score: https://forums.anandtech.com/threads/zen-4-builders-thread.2605910/post-40890893

This is what I got on my Dell Optiplex work PC:



This is the best of three runs.

No other software should be running as it will result in lower scores.



Compare feature for DDR3 shows bandwidth is acceptable but latency could be better.

Up up up I go. Not sure I can get any better than this at 6000. Ran stress testing for over three hours for stability. Will run more to confirm.

Interesting that your tweaking increased the read speed significantly to the slight detriment of the other values. Are you doing anything special to cool the RAM?

No, nothing special. The radiator fans on my 420mm AIO are directly above the modules. They don't spin very fast since I like to keep the system quiet. They probably help a tiny bit.

I recently upgraded from a 2700x to 5900x. I got a stable memory overclock, but I'm still working on getting the VDIMM down from the current "I know it is stable at this voltage" of 1.5v. @Justinus this is the kit you sold me.

Looks good.

I was wrong. I can go higher.

[AdamK47]

Okay, last one. Had to increase tRFC to 400 from 380 since stress tests would fail after a few hours. Still managed to get a higher score.

Chrome blocks the MaxxMem2 link as a trojan.

Edit: got it from MajorGeeks.

Another test with the new build. SAME RAM. Looks like enabling XMP made a big difference. I THOUGHT it was enabled on the old PC, but looking at the timing and speeds, maybe not.

Ran this on my new build and it doesn't show any of my PCs info. And it doesn't show latency. Any ideas?

This is stock settings T-Force 6000MHz C30 kit. So it's running @ 4800 40-40-40-77. Not far off from my daughter's PC from last month running at 6000 C36.

It probably can't retrieve the necessary info. Doesn't matter. Happens for me too on some PCs. Important thing is that you are getting the bandwidth numbers.

My daughter's new PC. No tuning, just enabled the EXPO setting. She has the same kit as lopri so it looks like I could tinker and get better results, but I've never messed with RAM timings and it is my daughter's PC after all, so I'll probably leave it as is.

With XMP enabled not much improvement. And mu C30 kit is slower than my daughter's C36.

Try comparing the Zen timings. That might help to get similar or better BW numbers with some slight manual tweaking.

My 6000C30 Trident Z5 Neo kit at EXPO + increasing to 6200/2067FCLK + Gigabyte high bandwidth/low latency settings.

Not too shabby. I am upgrading to the newer 64GB kit of Trident Z5 Neo 6000C30 that has looser subtimings, so I have no idea how that will perform out of the box. Might be different dies so it may or may not run at 6200+

Here's the EXPO + Gigabyte settings timing profile:

Finally had some time to check this. I have a lot to learn about memory! Not sure why her memory is reporting as DDR4. That's weird.

DDR4-6000 is very impressive indeed.

 

[igor_kavinski]

Weird that there is no Raptor Lake DDR5 score here. Let me ask on the Raptor Lake build thread.

 

[igor_kavinski]

Got DDR5-7000 working on my 12700K.

 

[igor_kavinski]

A very kind user ran these benchmarks for me, without and with 7-max.





Specs:

285K
ASROCK Taichi OCF
DDR5-9400C42

The write bandwidth really takes off with 7-max!

My Arrow-in-the-knee-Lake rig:

 

[AdamK47]

Ran it today to see where I'm at. 64GB dual rank DDR5 6200 28-36-34 with 2200MHz FCLK on the 9800X3D. Been running these settings stable since early December.

 

[igor_kavinski]

^^^ Your Zen timings screenshot please and if possible, 7-Max boosted score too.

Wonder what things look like for @Det0x at almost 8600 MT/s.

 

[igor_kavinski]

I know I'm biased but my tool is lightning quick in providing the approximate latency

 

[igor_kavinski]

Again, this is me being 100% biased in thinking that somehow my tool is immune to different OS versions and more consistent:
