Mushkin DDR Redline XP4000
 

After the success of the old "BH-5" PC3500 LVL2, Mushkin tries to continue the success story with the new Redline XP4000. They select the best Winbond UTT CH-5 and use them on these modules to have a big clearance above the specifications. The modules offer 250 MHz with tightest timings of 2-2-2, but require active cooling. We test these sticks at up to 3.5V and see how far they go.
