nice work zolkorn as usual =)

maybe p55 or its equivalent they will show some mercy?

~ 215MHz if only Spi1M :)

Thanks m8 :up: well from my ideal i think QPIclk it can't run over 4000MHz coz
after i tried alot of time to pass it over 221 to 222.xx(setFSB can't adjust on 222.00MHz :()
it failed every time because if Bclk over 222.5MHz QPI will over 4000MHz you can calculate from....

QPIclk = Bclk x QPI multiplier (4.8GT=18x, 5.86GT=22, 6.4GT=24)

btw. maybe 222MHz Bclk it'll work on my chip if i adjust it by ET6 coz 222x18 = 3996MHz QPI :D

maybe time to fire off an email to GB guys and see if Intel has allowed for some more ratios to reduce qpi frequency heheheh

Yah... i forgot something!!! EX58-UD5 it have lower QPI for setting but... why i haven't try on it :p: so next time i'll try ;)

it does?
sweeeeeeeeeeeeeeeeeeeeeeeeeeeet :D

Yep! look at from bios screen it have " Slow mode " for setting ;)

i should have my board soon
cant wait to do some testing.....i hope that slow mode will alow to break past 220MHz QPI

that would certainly save ppl money and let them buy and bin 920 chips :D

if that slow mode is something like x28 i'm gettin a boner right now :D

i'm assuming that you get QPI speed by dividing 8000 by those numbers

so 8000/36=222MHz
8000/28=285MHz DROOOOOOOL

285*20 =5700MHz boioioioioioioioing :D

hmm.. let me explan about some i7 to you
1. BCLK just a base clock and nomatter cold or airflow, perform the same
i can run 222MHz with StockFAN and very hot.
2. QPI BUS = BCLK*QPI Multi ( 4.8GT/s by x36,5.86GT/s by x44, 6.4GT/s by x
48) n it's not hard to figure out how much Maximum QPI Bus can go. i see
many x58 both stock around same range.
3. QPI BUS not affect too much performance, i have explaned to some friend
of mine, but it affects to server platform.

interesting

thx for showing pic zolkorn

lol Dino, ya lets hope

thx for explanation Hicookie

What is the difference between UD5 and UD3P ?

Slow mode with a BCLK of 133 MHz results in a QPI clock of 67 MHz. I didn't do any testing with the board, because the board I have at hand doesn't want to boot as soon as I change the memory multiplier in BIOS with a 965 XE. With a 920 it works fine, but I am doing the roundup with a 965 XE, so I have to wait for another board =/

But 67 MHz sounds like it will be way slower than 4,8 GT/s.

Slow mode doesn´t help for higher BCLK...

my max. is 222Mhz, but i have also some problems....

My i7-920 doesn´t work with multiplier 20 over ~190Mhz BCLK, with multi 19 is 218Mhz BCLK benchstable (3D) and 211Mhz Primestable.

Thank you for sharing infos bro! ;)

btw. your QPI multi and my QPI multi it same time hahaha but you'r multi twice with me ;)

Yes! Slow mode doesn´t help for higher BCLK i already tried it again today too :(

Maybe new bios will fix it ;)

i tested Bios F2, F3a, F3d and F3e... slow mode doesn´t help ;)

ah ok
so limit is somewhere else

i wonder what is limiting the BCLK clocks

lovely results ZoLKoRn :D

btw anyone tried freesing the x58 chipset yet?

Nice clocks, interesting about those temps - good to know my Kayl Black FrozenSS 1/4HP will have some use hehe

My Max on water with i920 was about 4510 Mhz, SuperPi (1M-32M) Stable and also SS max.
On Dryice i was able to Push about 150Mhz higher, 4650 Mhz, SuperPi 1M stable with 4 Cores (HT=off).
That is what 99% of the chips will do, some rare chips made it to the 4800Mhz zone.

does anyone have a theory on why they arent responding well to subzero?

Your setup is making me think that water is enough for them.

Do you know what your water temps are looking like? do you think the GTZ really transfers heat well enough for the i7's?

To the OP this is a great clock for a base chip!
