well done now !!! however, your efficiency per Mhz is to be improved :P what the max fsb of that chip? :) Ps: date is wrong :o :D

is that one? http://hwbot.org/submission/3885200_tagg_cpu_frequency_core_2_quad_q9550_4780.55_mhz

Yep, same chip, as a matter of fact I only have one

Efficiency was never my thing I don't like tweaking, just clocking

It really likes voltage with LN2 and ~1,9V this chip probbably will do 570FSB...

You guys seem to be having fun, maybe I'll join for some quad core fun. As the FSB is low I can use the 1:2 divider on the EP45T.

yeah crazy to see you do fsb every 5 Mhz and never anything in between

I am glad you don t like tweaking but with your chip you should be able to get in spi32m top3 scores, probably #2. I can do #5 with 150 Mhz less than your frequency...

what are your full 4-4-4-4 28 timings? your d9gmh ram won t do trfc 20-21 ?

your chip has a Vid of 1.15V, which is very nice. would you have the batch number?
I ve had L847C Vid=1.1625 and currently L845B Vid=1.175V, but on air/chilled water they heat up too much (more leakage current perhaps?) and are less stable than those with higher Vid, (1.23, 1.25, 1.26, 1.28, batch L828b, L835B, L845B, L846B) which heat up less.

Low Vids "should" be better on cold, a bit like yours i d say...

it is no fun when guys with big DOD SS LN2 come in

CPU is L845B869, haven't tryed TRFc 20 no idea, what the subs are, left everything except primarys and trfc at auto

I might try measuring power draw, shouldn't be too much at 1,74V the cascade runs -90 under x265...

thanks for sharing that
your Vcore seems fine, I ran mine at 1.68-1.72 V depending on the mood, same L845B batch. your cooling kills, clearly. -90c underload seems great
here on chilled water, it goes to 40C or so underload, starting at ~5C

well, I shouldn t give you all the good tips hum, but your ram surely can be optimised better than it is.

if you have a memset screenshot, send it
