could someone link me to arshia's hwbot profile? It's like the user doesn't exist, can't be found through hwbot search. Google also shows no hwbot profile.

I see, that was 26 tRAS on a 7980XE which supports 26 tRAS. I'll also add that the Wikipedia definition that GN used for tRAS wasn't entirely correct and I'll explain.
Wikipedia: “The minimum number of clock cycles required between a row active command and issuing the precharge command. This is the time needed to internally refresh the row, and overlaps with tRCD. In SDRAM modules, it is simply tRCD + CL. Otherwise, approximately equal to tRCD + 2×CL.”
This was the definition GN copied, the first two sentences in this definition are correct but the last one is not. tRAS in SDRAM is able to be below tRCD + tCL as the internal data is already pulled out of the physical memory cells into the prefetch buffers after 1 physical memory clock cycle (4 physical I/O clock cycles). Due to this, the memory is already able to be precharged.
Actual minimum ACT to PRE command period for reads is tRCD + tRTP.
I assumed 8th gen because of the chart above it was with an 8700k, my mistake. Yeah i don't know anything about x series intel stuff, never messed with it. I just use a 9900k because gaming.

Here is the GN video from 2018. It's written that they booted with tras 26 in the tras timing explanation on the webpage. It was 8th gen.

There is a chance that it auto-corrects to the lowest possible value if the bios supports that functionality, even if this happens it will still display the lowest possible value since that is what is in the cpu's register.
Understood. I don't know as much as you guys. Just theorizing here to be honest. But if you think its fake, have a moderator analyze it to be sure. I would maybe contact a moderator first in private before calling someone out, just incase you are mistaken. It can save yourself from having to make an apology later on if you were incorrect. If the person was sponsored or in the process of landing a sponsorship deal and wrongfully accused, they could sue for libel if they suffered any damages/losses from the incident. Always cover all angles. I do respect the questioning of authenticity, it is important. With that said, I also welcome moderators to analyze my recently posted result and have no problem running it again if need be, I could even take camera footage of everything if that is what they desire though I think my screenshots will suffice.

What platform did Gamers nexus use to boot sub 28? Can you link this video?
I'm just curious because not all intel platforms are limited to 28.
It was an older video, he said they got into windows with tras 26 if i recall correctly. I only have 1 year desktop oc learning so I don't know everything but i'm just repeating what was in the video. I will see if i can find it. I think its on the gn website actually. I think it was maybe 6th gen or 7th gen. ALso, if it can't read said value if it is lower than default, is there a chance it displays to the lowest default value if it was lower than default? Can someone test this?

Moderators can detect if a screenshot or result has been modified in any shape or form. Photo metadata can also be analyzed. Sometimes hard rules like tras at x value isn't always concrete, though I cannot speak for amd. Somewhat related but unrelated, Gamers nexus went into this in a video when they somehow booted on intel with tras less than 28, but again that was intel and not amd platform. I'm in no way defending anyone here. I just wanted to bring this up.

Looks pretty good to me. RTLs and IOLs need tweaking, and the subtimings could use some work to bring this OC to its full potential.
I wouldn't call this best configuration worldwide. Hardwareluxx, overclock.net, chiphell, and Facebook are all likely to have competition.
Thank you :). z390 aorus master does not allow rtl/iol adjustment at 4000mhz+ to my knowledge. Subtimings have been brought down as low as they can go without performance suffering while still maintaining stability.
I have searched all of those websites, also clockem up and malaysian oc websites. I could not find a better performing ambient memtest stable Z390 4x8GB Configuration anywhere. I also posted this on ocnet. No one has come forth to dispute my #1 claim. I don't mind correcting myself as long as someone provides proof of concept as I have done. -
Hi HWBOT. Duplicity here.I bring to you my result of 1 year of desktop OC learning. I aimed for #1 ambient memtest stable Z390 4x8GB Configuration Worldwide because i cannot afford to do ln2 or exotic cooling right now. I understand that there is no database ranking for memtest stable results so i did my best to make sure that I could not find another better result when it comes to bandwidth/latency for this configuration before claiming #1 position. If by some chance I missed one or if by some chance i am incorrect, please bring it forth so I can correct my statement about #1 worldwide, retail products only. I do not wish to claim any title that is not rightfully mine. Shout out to ocnet, you guys are great. I appreciate everything you have taught me so far.
To accomplish this result, I used the following:
retail 4x8GB Gskill tridentz rgb 17-17-17-37-2T 4000mhz ram kit (full 32gb usable in windows) - heatsinks/rgb still attached
retail z390 aorus master
retail F9 stock bios
retail kraken x72 360mm aio, 3 factory included fans on rad @ 2080rpm, pump @ 2700rpm
retail Conductonaut between IHS/AIO copper coldplate
retail 9900k R0 stepping chip, NO delid
Free windows 10
retail Karhu ramtest w/ cache enabled 6,400% error free
11 case fans total, 2 fans dedicated to blowing on ram(120mm blowing over the ram, 40mm blowing between the ram) and a 140mm dedicated to blowing over vrms
4 foot long cardboard box contraption routing from central air conditioning ceiling vent to blow cool air into top of PC case, aio fans are intake at top of case
Ambient never below 70F, central air conditioning thermostat set to 70F.

Fairly certain there would still be a profile link on google to his profile though, it just would just direct to not found page. I deleted an older hwbot account before when i thought i was quitting OC awhile back and it still shows up in google even though it no longer exists.
o yeah, almost forgot to mention, i did a second memtest, longer duration than the first and video recorded it. I added it to my post, feel free to verify the authenticity. I'm sure you or someone else already inspected all the photos though.
