warming up my cascade with DFI LP UT X58-T3EH8 and i7-920.. (230 bus speed achieved)

[Solarfall]

hello fellow XS members i've been playing few days with my new toys.. here are the preliminary scores that i was able to achieve.

the gear that was used:

DFI LP UT X58-T3EH8
core i7 920 patch #3841A347 so far this patch seem to be very rare picked it up from ebay
Corsair dominator ddr2 1600 mhz 3 gig triple ram kit
WD raptor
geforce 9800GTX
2 stage cascade ( build by piotres)


lets start with the bench marks shall we first wprime 32M good god those 8 threads are fast


next on the line we have wprime 1024M



mandatory super pi 1m score.. some strange thing is happening with my system i cant run super pi 32m at any clocks. seem like i need to re-install window



and finally max screen... so far

Great start!!!

Any vantage CPU tests yet? That will be interesting

[Sampsa]

Great results with i7-920

[miahallen]

Good start! Keep pushing it

[Solarfall]

yes sir.. right after i've gotten all cpu tests category's that are in hwbot im tackling 3d benchmarks next.

Great results with i7-920

thanks sampsa its always nice to hear kind words from the veterans

[Viss]

Very nice Any luck with multi x22 ?

[TheKarmakazi]

Great work! I was very surprised to see the bclk you were able to run wprime 1024M at!! awesome!

[eva2000]

Nice.. ya prompting me to go back to testing for max bclk on my DFI UT X58

for 32m you may need to play with subtimings i.e. tRFC and possibly more vdimm/cpu vtt

[Solarfall]

Very nice Any luck with multi x22 ?

i did even try yet.

Great work! I was very surprised to see the bclk you were able to run wprime 1024M at!! awesome!

actually i did one run with 227 but right when i was saving the result the damn system crashed ..i will just have to push more

[Oliver]

good work man, seems like you got a nice combo

keep pushing it

[Hazzan]

awesome result...now we can see that board like monster ....

[Solarfall]

good work man, seems like you got a nice combo

hehe dont worry i will keep pushing it

awesome result...now we can see that board like monster ....

yeah aint that the truth btw thanks for the bios template that you had in your thread a while back. it helped me A LOT

[clon22]

Awesome results!
Awesome cpu there Solarfall.

[Solarfall]

Awesome results!
Awesome cpu there Solarfall.

thanks mate i know that this cpu is pretty good

time for a small update.. i found today what my problem with super pi and pifast was my ram. these sticks totally SUCK !! not even raising the ram voltage to 1.85v dont make em stable..damn it !! i think i need to start to look for another pair

[SF3D]

Are you sure, that it is the ram? What VTT/uncore voltage you are using? (Measured from board)

Well.. really good tri channel kits are not so expensive.

Oh.. and very nice scores ..4.83GHz with that price is awesome!

well im pretty sure its the rams fault but i will have to test other vtt volts too to confirm its really the rams fault. the vtt/uncore voltages i already tested were between 1.55 and 1.63v

[eva2000]

check your subtimings as well which you left on AUTO, hence why i was curious about memset/cpu tweaker screenshots

REF to ACT Delay (tRFC): AUTO
Write to PRE Delay (tWR): AUTO
Rank Write to Read (tWTR): AUTO
ACT to ACT Delay (tRRD): AUTO
Row Cycle Time (tRC): AUTO
Read CAS# Precharge (tRTP): AUTO
Four ACT WIN Time (tFAW): AUTO

[joker_x3]

nice results =)

[Solarfall]

i tested the subtimings and no go.. its like anything over 830mhz with any latency ( i even tested cl10) or voltage and the superpi gives an error at some point.. lol i guess i just have to tighten up the latencys cos this damn things just refuse to clock any higher

nice results =)

thanks mate and to XS

Maybe even more voltage to Rams ? I know it kinda looks like a suicide mission, but it worths a shot ...

BTW, great results mate, your 920 is a hell of a chip !

i already tested 1.95v for the ram and it didnt help... this is sooooo weard i've never owned a kit that overclocks soo poorly

Wow! Sweet stuff brother!! Haha, you even gonna look back now?

[Solarfall]

Wow! Sweet stuff brother!! Haha, you even gonna look back now?

thanks bro.. heh im still gonna keep my 775 stuff for those bench programs that use only one core.

update time. as you can see my superpi 32m time sucks cos of the memory, my dominators just cant handle higher clock speeds so there is not much i can do. i ordered a pair of new sticks today and im hoping that im able to improve my memory bandwidth by heaps.

[PcCI2iminal]

sick !!!!
congrats my friend

[Solarfall]

sick !!!!
congrats my friend

thanks mate i got to say this board is looking more and more impressive the more i bench with it.. when you find a setting that works its rock solid
