+================================================================================
+
+
+============================== RAM Overclocking ================================
+
 [ram_oc=0]
 Set RAM Overclock frequency in KHz.
+
 If you hang or get corruption or artifacts, try to reduce it.
+ `mem-bench` command can use almost all of the available bandwidth so it can be
+ used for a quick testing.
+ Actual stability can only be confirmed by `memtester` command on as high as
+ possible temperature for several hours and with a big test size.
+ Running a secondary GPU benchmark can help raise temperature.

- On T210 (Erista max 1996 MHz):
-  Only frequencies in the following list are supported:
-   1728000, 1795200, 1862400, 1894400, 1932800, 1996800
-  Suggested:
-   - 1862400
+ Any clock increase will also increase RAM power consumption like a CPU/GPU OC.
+ For example on T210B01, with 1z-nm ram, going from 1866 to 2133 causes a
+ 146 mW increase on active reads/writes which is 19.8%.
+ Any other state is affected only with a voltage change.

- On T210B01 (Mariko max 2133 MHz):
-  Any multiple of 38400 KHz can be used.
-  Suggested:
+ Warning: On T210B01, GPU minimum voltage might be raised if very high RAM
+ frequency is used and GPU binning is low.
+
+ T210 (Erista max 2133 MHz):
+  List of supported frequencies:
+  1733000, 1800000, 1866000, 1900000, 1933000, 1966000, 2000000, 2033000,
+  2066000, 2100000, 2133000, 2166000, 2200000, 2233000, 2266000, 2300000,
+  2333000, 2366000.
+
+  Input frequency is generally normalized to one of the above.
+  Actual frequency will differ a bit.
+
+  Suggested Jedec Frequencies:
   - 1866000
   - 2133000

+  Suggested Custom:
+   - Any, if it works.
+
+
+ T210B01 (Mariko max 3000 MHz):
+  List of supported frequencies:
+  1866000, 2133000, 2166000, 2200000, 2233000, 2266000, 2300000, 2333000,
+  2366000, 2400000, 2433000, 2466000, 2500000, 2533000, 2566000, 2600000,
+  2633000, 2666000, 2700000, 2733000, 2766000, 2800000, 2833000, 2866000,
+  2900000, 2933000, 2966000, 3000000, 3033000, 3066000, 3100000, 3133000,
+  3166000, 3200000.
+
+  Input frequency is generally normalized to one of the above.
+  Actual frequency will be exactly one of these.
+
+  Suggested Jedec Frequencies:
+   - 1866000
+   - 2133000
+   - 2400000
+   - 2666000
+
+  Suggested Custom Frequencies:
+   - Any, if it works.
+   Very high ram frequencies might raise GPU power draw on some GPU frequencies
+   if GPU binning is low.
+
+ Timing based overclocking:
+  To enable that, edit the last [2 (T210) or 3 (T210B01) digits] of the frequency.
+
+  It's generally better to find a good base frequency before touching these.
+
+  Do not touch them at all for guaranteed stability on max possible frequency,
+  since without these, the whole configuration is exactly per Nvidia's and
+  RAM vendor's specifications.
+
+ Syntax:
+  T210:    Freq MHz +  BA. FFFFF[BA]. (18624[00] -> 18624[52])
+  T210B01: Freq MHz + CBA. FFFF[CBA]. (2133[000] -> 2133[252])
+
+ Description of F, A, B and C timing overclocking options:
+  [F]: Actual clock frequency. Exceeding chip's real max is actual OC.
+
+  [A]: Base Latency reduction.
+  Base latency decreases based on selected frequency bracket.
+  Brackets: 1333/1600/1866/2133.
+   - Range: 0 - 3. 0 to -3 bracket change.
+   Example 1: 1866 with 2 is 1333 base latency. Originally 1866 bracket.
+   Example 1: 1866 with 3 is 1333 base latency. Originally 1866 bracket.
+   Example 2: 1996 with 3 is 1333 base latency. Originally 2133 bracket.
+   Example 3: 2133 with 2 is 1600 base latency. Originally 2133 bracket.
+   Example 4: 2400 with 0 is 2133 base latency. Originally 2133 bracket.
+
+  [B]: Core Timings reduction.
+  Timings that massively get affected by temperatures are not touched.
+   - Range: 0 - 9. 0% to 45% reduction.
+
+  [C]: BW Increase. T210B01/LPDDR4x only. RAM Temperature limited timings.
+  Can cause significant ram data corruption if ram temperature exceeds max.
+  Reason is not allowed on T210 and LPDDR4.
+   - 0/1/2/3/4: for max 85/75/65/55/45 oC
+
+ RAM Temperature is only related to MEM/PLL sensors and not to Tdiode or Tboard.
+ 45oC is 50/51 oC MEM/PLL (around 43 oC Tdiode, depends on temp equilibrium).
+ 65oC is 68/69 oC MEM/PLL (around 60 oC Tdiode, depends on temp equilibrium).
+
+ Full Examples:
+  Old (no timing adjustments) OC equivalents:
+   - 1862 Old OC: 15% -> [A1,B3,C0] - 1866031
+   - 1996 Old OC: 25% -> [A2,B5,C0] - 2000052
+
+  T210 Examples:
+   - 19968[00] -> 1996800: 1996 MHz with read/write base latency of 2133 MHz
+                           and proper 1996 MHz core timings.
+   - 19968[00] -> 1996852: 1996 MHz with read/write base latency of 1600 MHz
+                           and reduced core timings by 25%.
+  T210B01 Examples:
+   - 2666[000] -> 2666000: 2666 MHz with read/write base latency of 2133 MHz
+                           and proper 2666 MHz core timings.
+   - 2666[000] -> 2666252: 2666 MHz with read/write base latency of 1600 MHz,
+                           reduced core timings by 25% and up to 65C operation.
+
+Again, do not use them if you want the ram running like Nvidia and RAM vendor
+made the tables, and write the frequency `as is` in that case.
+
+
+[ram_oc_vdd2=0]
+ Changes VDDIO/VDDQ voltage for T210. VDDIO only for T210B01.
+ Can stabilize timing reduction or if at frequency limit.
+ Do not use for zero reason. Limits are fully safe (official Jedec).
+ Range: 1100 - 1175. (Unit in mV).
+
+[ram_oc_vddq=0]
+ Changes VDDQ voltage for T210B01.
+ Can stabilize timing reduction or if at frequency limit.
+ Do not use for zero reason. Limits are fully safe (official Jedec).
+ Range: 600 - 650. (Unit in mV).
