8 PACK MEMORY RANGE GROWING: SAY HELLO TO 8 PACK RIPPED EDITION & 32GB KITS!!!

@opethdisciple
Your originally posted screenshot did not show the memory details top right of the membench screen which is why i queried it.
Version 1.73 of Dram calc as i have said previously seems buggy. if you use version 1.70 it behaves correctly and does not lose the imported XMP details no matter you select manual, fast etc.
version 1.73 loses the data and also fails to populate some of the data eg gear down can be blanks.
I was watching this thread to see if these were better than my patriot Vipers but on present membench scores shown they are nowhere near as fast hopefully thats just down to not having tuned them yet.

You can get Easy Membench scores of 105 and below using 3600 timings for Memory and IF and remain stable.
Whether its down to being lucky and getting perfect match of components I do not know. Maybe I got very lucky.

@Space Monkey
As Inoton says your XMP settings have some really slow values that will be hurting your membench scores a lot.
You really should be able to get close to if not beat the shown best results for membench and remain stable doing so.

Although motherboards may have a big impact I guess as i put my unused 8 Pack 4000 into a MSI B450 Tomahawk MAX and I could not get anywhere near the timings my Asrock Taichi X570 can run.

I think tfaw and trfc tweaking will massively improve your scores.

Trrds seems high. Aim for 4 and trrds*4 for tfaw.

Then get trfc to about 300-350.

Youll knock 20seconds off...

Done as you mentioned and this is the new Bench time, strange thing is though that my trfc was set in the BIOS under XMP of 315 but the DRAM Calculator read it as 688? So I manually set it to 300 as a test and the result is below:

Hmm I have a feeling the dram calc is giving me incorrect secondary timings.

I am probably best doing what @Space Monkey is doing and that is use the stock timings (14 15 15 35) and auto secondary and just tweaking the secondary by hand as you've done above.

Alternatively I could try version v1.70 as @Shac mentions

I've just tweaked a little bit more and got down to 219.52s, think I can get lower but happy with that for now :)

I compared settings on 1.7.0 vs 1.7.3 and there was only 1 that differed for my sticks and even then only by 1 point.

If I set it to 3800Mhz then the timings were noticeably different.

Can you tell us what settings you changed please? :D
 
Look good.

I'm currently 110 easy and 210 default.

Might be able to shave a couple of seconds off, but it isn't worth my time.
 
Here's mine using the same timings as space monkey.

Similar latency and read and write speeds but still not as good bench time.

Anything else I can do to improve this?

As already said tRC should be = tRAS + tRP so for you change to 42.
tWR seems very high mine is 12.
You also have gear down mode enabled which i would not have thought necessary at 3600 and with only 2 dimms .

The above are the major differences if I run version 1.70 as profile V1
Memory rank 1 and 2 dimm modules.
 
I went and grabbed timings from 1.5.1 dram calculator and this is what I got:

I've tried turning off GDM numerous times and results in immediate memory errors when testing.

Your see that these now follow @Shac advise.

I will go and have a look at 1.7.0

Best yet, had to use 1.5v on the ram to get there but its stable and error free so far. I'm done with 3600 now, want to settle on 3800 with matching FLCK :cool:

Hmm

I will try to see if I can turn off GDM but I am already at 1.47v and the bios overvolts it to 1.488-1.5v so anymore and I will be over 1.5v.

I'm now at 1.51v and with GDM enabled at 1.5v Igor a blue screen during memtest.

Mine will definitely not do GDM off.
