If you really want to fine tune your memory, let's start with 4000.

By the way, guys, how are you?
What is the advantage and/or effect of setting the _DD to 0?

Removed the stock Ripjaws heatsink from my 32GB 4266C17 kit now sticks are running 3-4C cooler with a 100% noctua fan. Improved Vref/ODTs now I don't need slopes (auto slopes).
32GB 4600 17-17-17-32 1.57v DRAM 1.32v IO 1.33v SA 2H GSAT and 1H Ramtest

i9-11900K (SP89) @stock---4800Mhz-C19-28-28-48-1T----1.66V---SA 1.2V---MCIO 1.26V---Stressapptest----1 Hour

Trying mem OC on my SP89, turns out the IMC is a lot more finicky requiring specific voltage ranges for SA/IO to stay away from errors.

My SP85 would train 5066MHz C20 1T easily though it needs a little more voltage in the IMC and does away with 10-20mV less VDIMM at each frequency point. SP89 has a noticeable hard wall with memory scaling, mostly no POST up till 1.4V SA/IO for 5066 C20.

Might attempt 5066 C20 1T GSAT 1H on my SP85 soon.

Hi, I've been trying for 2 weeks and still can't get below 40 latency
Maybe someone will suggest?

Enable trace centering also. RTLs look a little off, might need to train again
tRRD_L at 6. tRRD_S at 4
Loosen tRAS to 34
Loosen tRTP to 8 and tWR to 16
Retrain memory see what happens.
Your RTLs are 58/65 to far apart

Where is trace centering? And what it does?

Made some progress, this is my current daily configuration. Next up is to reach 70K Read/Write while sticking with CL16 if possible.
  • 4444 MHz 16-17-17-32-2T
  • VDIMM: 1.590 V
  • VCCIO: 1.390 V
  • VCCSA: 1.375 V

Looks good, put it through LinX 0.9.10 or 0.9.11 for an hour at 35k problem size to make sure you are calculating properly. If the residuals don't match, it means you are unstable.
So far this OC has survived GSAT (2hrs), TM5 Extreme (3/3 cycles), and Karhu (15K%), but I'll give LinX a shot.
I haven't used Linpack Xtreme before, is there any reason I shouldn't be installing the latest version, 1.1.15?

Far too many people swear by outdated versions of Prime95 because of misinformation surrounding AVX.
The newer P95 builds are more stressful, find errors faster, and give you the option to disable AVX if desired.

ripjaws b-die owners come here!

how much voltage you have on your sticks before they become unstable at lets say 330 trfc 65024 trefi? Do you use fans at them? Mine have a decent potential but i always get 1-2 errors at 13-14 minutes of TM5 superlight2

Does anyone know if you contact gskill to void the product warranty that they will remove the artificial voltage limit?
What do you mean by artificial voltage limit?? Your bdie still scales over 1.5V it just can't hold full capacity stable above that voltage, this differs along kits. Both my g.skill kits take 1.6V+ stable full capacity.

I had it at full capacity 1.55v 16-16-16-34-2T 4400mhz fully tightened subs LinX stable, results are posted within the last 15 pages(estimate). I also had it aida64 simultaneousl cache/memory tested stable with full capacity. I also had it hci stable with full capacity. I'm 100% certain being artificially voltage limited, i can literally see in real time every time they make a change, My modem wifi blinks right before instability kicks in EVERY SINGLE TIME. I use ethernet cable to internet. 20 out of 20 times wifi modem light will blink/flicker a second before they become unstable. It's not a coincidence. Had them in p95 large fma 3 at the c16-4400 1.55v profile within the last week, same thing, wifi light flickered/blinked and then the test failed. They are artificially limiting me. If I void the warranty, are they gonna let me pump as much voltage as I want for daily use or no? I already know these dimms can handle the heat, had them up to 47c no errors just fine.
Are you sure is not a temperature instability ? Slam a fan on them and try again. B-Die is verry sensitive about temps.

Are you suggesting that g.skill is sending some signal via internet to artificially throttle your ripjaws? Sounds pretty far fetched.

Judging by two over 2000 word dm he sent me and then blocks me straight after thinking I work for gskill he’s had a couple too many drinks.
