Guys i have a good news for cheap btd43 owners...
some guy here suggested that burning in btd43 would result in no increase in performance...but that doesnt applied to me..

These last few days, i ve been running a burn in session with 2.85vdimm for few days---my result before burning in was a decent 264htt.. After a few burning in session, i manage to break 265 and now 2hrs walltime running at DDR540 (270htt) stable so far....i dunno how far this chip can go..but im expecting it to reach max at 275..hopefully..running at 2T of course..Have yet try running 1T

i manage to run memtest stable at 275htt all test stable for 14hrs..
and test no5 stable for also 10++ hours..

so i can conclude:

275htt @ 2.5-4-3-8 @ 2T

Impressive for rm350 ram...
