  HyperX PC 3200ULK2 (2-2-2-5-1T) (KHX 3200ULK2)
  Apacer PC4000
  Centon Advanced DDR

"+~300 Mhz" = for sure over 300 Mhz, except rarity.
"~-300 Mhz" = around 300 Mhz, largely under 300 Mhz.
"-300 Mhz" = under 300 Mhz of about 5*(2,)3,4,5(,6) Mhz except rarity.

With V-RAM ~2,85V and relaxed timings.

Winbond UTT vs TCCD (indicative comparison, not scientific):

• Low Timings 2-2-2-X:
  Winbond UTT (265-270 Mhz 1T @ ~3,4V) > TCCD (235-240 Mhz 1T @ ~2,85V)
• Medium Timings 2,5-3-3-X:
  TCCD (~300 Mhz 1T @ 2,85V) > Winbond UTT (270-275 Mhz 1T @ 3,4V)
• High Timings 3-4-4-X:
  TCCD (+300 Mhz 1T/2T @ ~2,85V) > Winbond UTT (275-280 Mhz ~1T/2T @ 3,4V)
• Consumption (max = at which voltage they give their max):
  TCCD: ~2,85V (max)
  Winbond UTT: +3,4V (max unknown)
