I have an Asus B450i Strix, 2700X and 2x8gb FlareX.

I cant use more than 1V SOC then it fails much much faster than 1000%. I am using PBO 3 with offset from -0.1 to -0.05, doesnt seem to make any difference.

Would it be better for me to try for 3466 even tighter than fast or going for 3600 fast?
I've found that the closer I push my RAM to the edge the more sensitive it becomes to temps. Can you try testing while actively cooling your RAM? Or just removing a panel from your case? And what voltage are you running for DRAM?

I ran 1,44V and 1,45V. I can try to cool them and try more. I tried cad bus settings around 20 too but i cant even boot with 20 20 20 20 on the last bios. Is there any noticable gains to be made primarily for gaming going for 3600?

@Iceman1985
1. Set cpu to 1.35v or lower with auto ratio, llc's to 4.
2. SOC 1.024-1.075 or 1.1 and check temps/errors
3. try Dram V from 1.39 to 1.45 by +0.01
4. SCLs to 4 or 6 \ try set CADs, RttWR, RttPARK, RttNOM, tRTP, tRDWR to auto

Hi guys, I need some advice.
I'm trying to stabilized CJR kits @3800c16 on my Asus B350i platform.
I have tested and configured some settings necessary for stability, including procODT, RTT, DRAM & SOC Voltage, CAD_BUS, tRDWR & tWRRD, tFAW, tRTP, tRCD and tRP.
Here's some notes. The first part is tuning 3733c16, the second is 3800.

The question is, a 5-cycles TM5 test, or even 50-cycles test, is easy to pass, but there always happens a single error in an 100-cycles TM5 test. This really annoys me, as this kind of single error will sometimes cause blue screen(happened on my x370taichi).
I'm trying to tune tRFC to fix this problem, will this be effective?

Hi guys, hoping someone here has some experience with Micron 8Gbit E-die memory?

I recently bought 2 x 8gb Ballistix Sport LT 3000Mhz (BLS8G4D30AESBK) and they seem to be a good bit of fun to play around with, but I need advice/help/info regarding some timings.

The be precise, the timings I would like to get lower, but just a small change results in a no post are the following..

• TRCDRD (17)
• TRC (56)
• TRFC (500)

Any help would be appreciated.

Attached is my progress so far..

Hi) I like your notes.
I want to please you, you have already received a phenomenal result.

1) Try to use tRFC as low as possible, since your remaining timings have tuning. For example 480 or 498.

2) Did you monitor the temperature of the processor / RAM for 100 cycles? LLC enabled for SOC?

3) B350 have insufficiently good screens for CAD (this is one of the key differences from older brothers), that is, the only chance to stabilize the system is the jewelry setting of the CAD

why do you have such low tRRDS, tRCDWR , tRTP , tFAW and too high tWR, tRDWR?
honestly I'm surprised they have stability

in your case the SOC will have a “hole” to a certain voltage, try 1.1 volts

Hi 1usmus, thanks you for the reply.

I used your DRAM Calculator to give a starting point, but in your calculator for Micron E/H the max frequency is 3466Mhz. I stayed with that because anything higher would give errors in memtest.

So, because I couldn't go higher. I just started tightening the timings. Primary timing hold the best latency improvement as far as I know, so I started with tCL, tRCDWR, tRCDRD, tRP, tRAS and tRC.

tRCDWR surprised me the most by going all the way down to 10. Believe me, I checked for errors at 16, 14 and 12 as well.

tRAS was also surprising because it is so much lower even XMP.

As far as the secondary timings, I just started tightening timings to see if they offer any further performance compared to the timings provided by DRAM Calculator.

One question I have, maybe I just missed something. In my bios I have 2 parts for CAD Sub settings.

In the DRAM Calculator it doesn't provide any values for the first part below..

First part is: CAD Sub Timing Configuration. (these are all still on auto)

AddrCmdSetup
CsOdtSetup
CkeSetup

Second part is: CAD Sub Strength Configuration.

ClkDrvStren [20 ohm]
AddrCmdDrvStren [20 ohm]
CsOdtDrvStren [20 ohm]
CkeDrvStren [20 ohm]

What values would work best there?

I wanna say I read something from AMD saying tFAW below 12 will bring instability, but I know I read this:
Configured to a minumum 4x tRRD_S, but values >8x tRRD_S are often used for stability.

I got that from:

Hi. Anyone has an idea whats the max safe 24/7 voltage to run a samsung e-die? I see some conflicting reports. Currently at 1.51v, and it scales really well with voltage so far (also when benching at up to 1.6v). I have a 120mm fan blowing on the ram. Tnx .
