Now it's recommending 15-17-17-17-32-49 timings.


I'll give it a try. I'm a bit worried about going above 1.35v on the ram voltage though. Is it safe?

1) download the new version 0.9.7
2) tRFC 260000 -> 260 or 260.000

and so all is well

For the voltage do not be afraid, memory even at 1.5 volts barely warms up

I get 500Mb/s difference between 1T and 2T, nothing to worry about.

I've seen people warn not to go over 1.4v. Why is that?

If you want your RAM to last 200 years instead of 100 years keep your voltage under 1.45V

What's the verdict on geardownmode? I've had it disabled for a while.

What I heard is that you can have Geardown mode enabled to improve stability a bit.

It is between 1T and 2T and the RAM itself changes from 1T to 2T "on demand".

Helps with stability. In my case:

3200 RAM:

1T: Blue Screen (sometimes can login but unstable)
Geardown:Stable
2T: Stable

3333 RAM:

1T: Blue Screen (sometimes can login but very unstable)
Geardown:Unstable (in HCI, tweaking tCKE atm)
2T: Stable

Stability while in Geardown mode can be tweaked with "tCKE" (Auto recommended, 6 is a good value)

Thanks btw.

EDIT: tRRD_S is reporting as -0,001 ns on thaiphoon burner for some reason. Is this an error or something wrong?
XMP is what Intell calls it
DOCP is the AMD name
It's basically the same. Think of it as a boost mode where the memory runs at a faster speed

And the -0.001 ns must be a glitch in the reading yes.
Suggest to use the newest Thaiphoon Burner available here

That's the one I got.
He says that if XMP doesn't show up in thaiphoon then my ram isn't XMP, but here it says it is

Okay so I tried to put the values using 0.9.7, and couldn't find anywhere in the bios the following things:
PLL voltage (there was two things, neither of them accepted the 1.8 value)
VDDP and the one below it have weird values (855 and 425), I don't know what I'm supposed to put.
tFAWDLR
tFARSLR
BGS

Also tRFC alt means it's another option for me to use?

I tried booting with all the values entered besides these, voltage from 1.375-1.395, couldn't boot.

I later tried 15-16-16-16-31-48 as the program shows, and 1.375 voltage. The rest on auto. I managed to boot, and ran cinebench 3 times. But then it BSOD when opening the browser.
I tried going up to 1.395 later but it kept BSODing.


Back to the docp profile now, 16-18-18-18-36-48, 3200mhz, 1.35v.

That is not Thaiphoon Burner issue. Before reading SPD, make sure your are not running any temperature monitoring and LED control software on the background. Otherwise SPD readings may be corrupted. In your case XMP profile was read with errors.

* Developed anew tRRDL, tRRDS, tFAW for all calculators, built-in automatic conversion of nanoseconds from 2T mode to 1T (in case of incorrect reading SPD)
* HQ and Without XMP calculators were recycled from scratch for accuracy of prediction of all timings, symmetry conditions for timings were added for improved stability
* Increased the accuracy of the prediction of tRFC
* Added the "Additional stability" checkpoint for all calculators and ranks (2T mode)
* The editing of the syntax "procODT 68.8 -> 68.6" etc.
* Changed the sequence of input fields for a more convenient copy-paste with typhoon

p.s. thank you guys for helping test and write reviews smile.gifwubsmiley.gif

When I get a chance, I'd like to experiment with Crossover Linux to see if this will run. @1usmus, have you determined whether your executable will run on earlier versions of Windows besides W10? I'm not sure if W10 is supported yet.

Otherwise, is your google version being revised to the same state as the Windows executable?
