[Team.AU] Core i7 920 does sub-8m 32M SuperPi

[dinos22]

Hi guys

Did some quick benching last night on SS and couldnt go to bed until i hit sub 8m time with this i7 920 chip :D

This motherboard is sweet......but i wish i could run higher QPI.......221MHz stable > another MHz up and it bluescreens heh....damn it Intel fix up this QPI limit :D
Gigabyte engineers also confirmed QPI is limiting bus speed

i could run same clocks with 2 and 4 cores...just thought i'd try the latter

I still havent tweaked subtimings in full as it was experimental
there is also a bit more tweaking to do...and have to figure out CW as its not working on i7 CPU

Test Configuration:

Gigabyte X58-UD5 F4F bios
Intel Core i7 920 retail chip 3837A899
3GB 1866MHz CAS8 DDR3 Corsair Dominators (TR3X3G1866C8D)
884MHz 7-7-7-20-1T TRCF-60, TRRD-4 1.9v
(didnt test higher lower just selected save volts for quick runs)
1GB Gigabyte GTX280 Graphics Card
1000W HX1000 Corsair PSU
1hp C-BuZz Single Stage (kayl evap)
160GB IDE Hard Drive
Windows XP Pro 32bit SP3



32M SuperPi - 7m 59.234s

1M SuperPi - 8.890s
Rol-Co says dual channel RAM runs faster in 1M so gotta try that next :D

very nice, time to open up a third color in the 32M LCC. it is killing me to have to watch from the sidelines...next week can't come soon enough.

hi dinos22,cpu tweaker can't adjust cas latency?and any newer version of memset available,is it adjust it?thanks,sorry my poor english

[dinos22]

nah man it cannot adjust it yet :(

[Movieman]

Nice Dino!:up:

[Warboy]

Dinos, Can we get a pick of the rig itself?

[TiTON]

Dino,

Awesome runs :) I see you using 1.52 vcore. What were the other voltages set at to get you 221 Mhz?

Ton

hi mate

very simple setup
Vcore was 1.52v in idle and load as i have the droop mod
vdimm was around 1.9v from memory
QPI volts 1.5v
pretty sure 1.4v was ok for QPI too but i bumped it anyways

thats it :)

[dinos22]

Nice Dino!:up:thanks mate


Dinos, Can we get a pick of the rig itself?yeah i have a big thread in my sig regarding detailed testing so lots of photos in there

[edit] here's one

[taymonxuytuyet]

so cpu tweaker just adjust all timing except cas latency?

[dinos22]

so cpu tweaker just adjust all timing except cas latency?

no. it only reads timings

i adjusted timings in bios

[T_Flight]

thanks mate

Wow it looks like you got the "full ride" with Gigabyte. Did they send one of those sweetie's too? :D

[dinos22]

won the card at one of the comps :)

[Hennels]

Go dinos! That picture looks great with all the blues :up:

[taymonxuytuyet]

yeah,i see,thanks dinos22,so still now,no tools can adjust timing for chipset X58?

[T_Flight]

won the card at one of the comps :)

It is pretty cool. Everything matches. hehe :)

[dread77]

Fine work Dinos!!! You totally maxed out that chip...:yepp:

[dinos22]

Fine work Dinos!!! You totally maxed out that chip...:yepp:

maaaaaaaaaaaaaan
i've squeezed EVERY MHz and KHz for that matter :lol:

[Kabauterman]

great work mate! :up:

whats max Bus Speed on air?
does the cooling improves the max Bus Speed?

realy nice memory dino! I am always wait for mine... *grml*

[dinos22]

realy nice memory dino! I am always wait for mine... *grml*

215MHz on air
so about 6MHz gain :)

[Achill3uS]

sweet run dino, 221bclk 32M stable is like wow, nice mobo :toast:

[SAE]

Hey mate, really top job there! :up:
Is that speed bootable? Do not see clockgen/setfsb there. :D

P.S. I wonder, yeah I am indeed wondering badly, how that guy got to 229MHz QPI... would really come in handy now.

[dinos22]

yeah bennys board or CPU is just a freak

i will experiement some more
i havent touched PLL and some of the other settings

doubt it will do anything but i'll try :D

i was booting at 215 which was my air boot test before i hit cold :)

[Bullet92]

Hy Dino, really nice run with un-tweaked subtimings. Let's play with the other settings that you've left and make some mess there :D

Sretno ;)

[Ghigo]

Benny bios was a special one, he sent it to me , when loaded show version as Dx, it dont have qflash util on boot and showed a orange light near cpu at stock boot, so i got a bit scared and avoid test it on my 24/7 on air pc ;)

If want test it dinos , pm me :)

[dinos22]

were you able to get similar clocks in QPI

[Ghigo]

I no tested it really, saw the orange light from default near cpu socket guessed is a subzero tuned bios ;)

My board is internation shipped no feel to kill it and do another international shipping for the rma.

Well the bios miss the f12 option on boot for qflash but entering the bios menu , qflash here work.

[dinos22]

I no tested it really, saw the orange light from default near cpu socket guessed is a subzero tuned bios ;)

what made you think that
what does orange light mean

send it i'll test it
just post here or PM me the bios

if it works i will get bios engineers to tell me WTF it does and if it would be safe to implement

[Rol-Co]

nice dinos22.....:up:

[dinos22]

hey man
thanks
i will do some dual sticks benching to see what happens with 1M like you were saying in the other thread

[Oliver]

awesome work Dino

your 920 is screaming man

looking forward to more numbers from ya

keep pushing it

[tiborrr]

Bravo Dino! :up: Keep up the good work!

[PcCI2iminal]

very impressive Dino
and I like that stability ,221MHz is just crazy :)

Gigabyte rocks by an Asus fan hehehe

[dinos22]

maaan i swear my next bench session will be spent on max bus speed
if i cant figure out how to run it higher than 221MHz in 7-8 hours straight i give up :D

EX58 Extreme maybe???

:D

[eva2000]

congrats dino - hopefully you figure out the bclocking soon...

i should have some nice cpus later this week as well - no board though LOL

[dinos22]

hey junior this board is good enough
i might get a 965 for higher numbers donno


congrats dino - hopefully you figure out the bclocking soon...

i should have some nice cpus later this week as well - no board though LOLwow avatar change finally :D
thanks mate
look forward to your testing :up:

[youngpro]

superb as per usual!

someone give this man a 965 and let the real action begin

[Spacemaster]

Awesome work mates :)
Go for 965 ;)

[TheKarmakazi]

nice going dinos! sub8 under 4.7Ghz :up::clap: strange how CW isnt working... So you can balance you mem but it has no effect?



very nice, time to open up a third color in the 32M LCC. it is killing me to have to watch from the sidelines...next week can't come soon enough.

Waiting to see some cherry triple chan kits :D

[dinos22]

hey fellas

small improvement :D

[mike]

thta's all the Gigabyte can do???? PFFFFFF!!!!

EDIT: just messing with ya - my bugged non gigabyte board can do 221.8

[jabski]

very nice results mate.

[mike]

very nice results mate.

very nice results indeed

[Dsjjang]

Nice run, dino~ :up:

[HDCHOPPER]

exellent dinos ! 920's are looking sweeter all the time :up:

[Bullet92]

Nice results again... What about your GB? Can do more than 221MHz?

He's probably talking about the voltage indication LEDs. Green for safe, yellow for warning, orange/red for high voltage. I don't have an GA-EX58-xxx yet so I don't know what the voltage scaling is like but I imagine red is around 1.6v :shrug:

[dinos22]

thanks guys :up:

many thanks to dsjjang for pushing me to improve some more :up: with his excellent tweaking on R2E board :up:

[dduckquack]

the next few months should be interesting for spi 32m, OS tweak-wise
