with only 9x225mhz i managed a great feet i think!

im only 850mb/s away from my fastest recorded everest read test, but im at a mear 225mhz!!!

it took a ton of tweaking but i got my BH5 @ 225mhz over 6500mb/s in everest read test :D

real memory timings are: 1.5-2-0-2

tried sandra real fast, over 6gigs bandwidth. :)

how much V do you give 'em?

When Benching I was running mine at 253MHz 1.5-2-0-0 3.5V most of the times;)...

nice dominic!
now crank up the speed :D
or cant it go higher with those timings?
what vdimm? :)

Notice the low CPU speed too guys :D

3.6vdimm via bios, 3.58 shown in windows.

ill give more speed a shot but these sticks at least didnt look like they wanted to go faster with these timings :p

Its possible to run 1-2-1-3
Turn volt up and set Async to 8 or 9 then it will boot.
Async 6-7 wont boot (for me)

async is normally 8 for me

cas1 just wouldnt boot.. wouldnt even post actually. :(

i noticed the BW differance from cas 2.5 to 1.5 was minimal though

yah cas really doesnt help much

put your ras to ras delay (trrd) at 1

and you wont get any decent clocks with the cas that low, keep it at 2 or 1.5, and u can clock just fine while tightening other stuff

ill try that. (trrd)

cas 2 -> 1.5 doesnt affect my clocks. i can still hit the same speeds 1.5-2-2-2 or 2-2-2-2. :)

Very nice results and tweaking Sporky! :toast:

May I also suggest TRRD of 1 (although it won't affect much bw wise), and a TREF of 166MHz 7.8us...I get my best bandwidth with my BH6 at that refresh rate, a good 20MBPS in sandra over the setting you use. Best of luck! ;)

i just remembered i used my poorer set of bh5 sticks for these tests.. maybe my others will do better?

There's only 1 way to find out. Put them in, pump 3.7 volts into them, and show us some great clocks.

you mean 3.8v+ ;)

once i finish tweaking this set, ill switch and see what the other does. :)
