now tell me how manny chips u tested befor u found this one :D.
None. First D0 I purchased off the shelf - 3850A796 from SCAN UK..Quote:

Look forward to seeing more results.
Thx Paul, this combo just rocks.
congrats again, bro~ :D
awesome result~ :up:
Thx man, I am shocked myself. Vdroop enabled so load Vcore only 1.4V..
nice result any stable on 3D bench ?
Have not tried yet, board is drying off now. Need to install the right OS too. Wprime likes Vista so I thought I'd get this in before I wipe and go over to XP.
wow, very impressive. Have you tryed this chip on any other boards? QPI link almost 4.3ghz is astonishing.
Impressive Score.. and 238BCLK :clap:
Tried on the REII with LN2 - board was locked to 222 BCLK (from BIOS 221, OS 222 max, 223 = no go). Sacha35 was with me so he can confirm.

Raja
again , outstanding work Raja and as for the board and chip , outstanding work from the respective also
keep 920ing it
wow and this is a retail classified with the nf200. Thanks for answering my question :up: Ive been stuck at 222 for so long its frustrating. Guess this will be my next board. Do you know why the classified can do this?Quote:

Very very nice Raja :up: Mine is 795 and i can only hope it wil do something simular with good board. Looking forward to 3D.
nice run, intels mastered their interconnects
congrats
wow great cpu and of course great results!
Keep it up!:D
Wish I had that cascade. :) Really nice results..
Very impressive!
Yes the Classified board is a work of art! truly a mastery of electrical engineering! Expect 5GHz to be the norm with all good i7 cpu's on that board :)
man these D0's are getting some seriously impressive numbers.. it took me almost that much voltage to get 4.2 with hyperthreading
the DO is a piece of work
the heat load hardly changes from idle to load with wprime @ theses vcores
great results raj
meh nothing special
:D :rocker::rocker::rocker::rocker::rocker::rocker:
that motherboard is UNBELIEVEABLE. That is probably even more remarkeable than the CPU to me.....238MHz QPI wPrime 1024M stable....crazy stuff
:up:
Insane speed ...
Batch Number ?
Lol Dinos, understated as always. The Classified has a couple of nifty features that help with cold benching. I might check out a Xeon W3540 next, seeing how this board can handle 8 thread high BCLK stuff for some of these benches. This one is the full retail board now btw, no longer using the early sample, so it's pretty darn good.
later
Raja
3850A796, they're getting better and better the later they are it seems.Quote:

the other chip has an extra multi right...that should be even more interesting. You'll probably reach the CPU limit before you reach QPI clock limit
Would you say that this QPI speed is CPU dependant or will the board be able to reproduce this sort of clockage on most chips from past experience.
something with shampin and kingmino or so :ROTF:Quote:

Higher QPI bus frequencies are very demanding of optimal signal layout etc, which is typically where EVGA and DFI do a lot of extra work and it is beginning to show now.
This 920 has incredibly low leakage, it draws only 140w at 4.6GHz with 1.438Vid (we checked with a clamp meter) when cold (-85). Conversely, it needs lots of drive current when at ambient so hits very high temps at low VID (not to be confused with gate leakage). Intel must have found a way to increase substrate density which really helps when you go cold.
Not sure how many chips are out there like this as many have not started to bench them yet, or are using boards lie the REII which has high BCLK issues anyway.
regards
Raja
oh i see
interestingly enough the CPUs that i;ve tried so far on Gigabyte UD5 have all come do a dead stop at 221MHz QPI basically.....everything benchable up to that point and then a restart when you try to go a hint better :rofl::D
i might try a new Extreme board they are sending with a D0 chip and see if things have changed i guess as last time i tested anything i7 at home, dinosaurs were still roaming the planet :D
That Gigabyte board sounds like the REII. This good CPU won't go over 222 on the REII for love or money with the current BIOS.
so do you owe these numbers to the chip or the board?
Based on my experience, both are important when you clock QPI this high and bench with HT on.Quote:

the extra $$$ for this board might be justified by being able to handle BCLK values over 220 and therefore not having to fork out the extra for the i7 965 and unlocked multis :p:
A few more runs today, nothing really tweaked over on XP now with 4870X2.

DANG raju !!!!! your D0 chip is truly spectacular.. i wish i had as fast as chip as you do hehe but it also could be cos of the super expensive classified board too, but never the less really impressive..
keep up the torturing dude :toast:
I wonder how that chip would overclock here in the USA. (at my house) :hehe:
Way to go Raja :wave:
Lol Ron, if I lived closer it would already have happened.
The cores on the chip are just plain nasty, I wish it had an unlocked multi. 5GHz wprime only needs 1.40V full load Vcore.
wow
nice cpu and awesome mobo
Come one Raja lets see 7.xx in Spi :D
Excellent results so far! :D
impressive work Raja, way to go man :up:
the Classified is simply outstanding and surely play in its own sandbox
keep pushing it
loving the scores raja, keep em coming!
test 06 and vantage cpu tests..?
Dam nice Raj mate... looks at my dated C0 920 cpu only managing HT enabled @4680Mhz on H20 cooling for super pi 32M hehe
how's the memory controller on D0 for >DDR3-2000-2100Mhz speeds ?
Just sick bclk. Makes the 920 a very attractive chip!
Great results Raja ! Turns out that Intel did a fantastic work with these D0 monsters :up:
Ohhhhhh Very Nice. Man im getting anxious for mine to get here!!!
Just wicked... :up:
grats....
great work raju, those BCLK numbers youre getting are incredible :clap: :clap:
Im just starting to play with my new D0 920 under my cascade on the Classified too...Im still trying to get my head around i7 overclocking though having not done much since socket 775 :D
so did you do much tweaking in the BIOS or mainly in the E-LEET tool? Totally understand if you cant be bothered with the below, but if youre feeling generous Im trying to work out the various voltages and multipliers you used in the Classified BIOS to get these speeds that youre getting hehe
Frequency Control
CPU Clock Ratio: 21X
CPU Host Frequency (Mhz): 239
MCH Strap:
CPU Uncore Frequency (Mhz):
CPU Clock Skew:
Voltage Control
EVGA VDroop Control ( With VDroop )
CPU VCore: 1.45V
CPU VTT Voltage:
CPU PLL VCore: Auto
**IOH PLL VCore: Auto
QPI PLL VCore:
IOH VCore:
IOH/ICH I/O Voltage:
**BR04 ( NF200) Voltage:
**VTT PWM Frequency:
**CPU PWM Frequency:
**CPU Impedance: Less
**QPI Signal Compensation: Less
ICH VCore:
*PWM Frequency:
you'll have to boot around 221~222.
Only voltages you'll need to fiddle with for your chip are CPU VID, VTT, Vdimm
Those 3 will be completely unique to your CPU and will also vary with temp
For 3d over 233, set IOH to around 1.30V. You can pass 3d mark 06 upto around 233-234 BCLK. 231 is rock steady for both 06 and Vanatage oon this CPU. 233 takes a few reboots at times.
QPI COMP and CPU impedance - again will vary with temp and the IOH.
I left all oter voltages at stock, no need to change them from their base values - even upto 245 BCLK.
later
Raja
thanks raju, I'll have a play around but at this stage Im only about to boot at around the 214 BCLK mark...might be CPU limited.
are you on air or cold?
Im playing around with it now on air (well air and a whole lot of dielectric and kneaded erasers hehe) but have the cascade waiting here to fire up when Im comfortable I know what Im doing with i7 ;)
But I thought that as long as Im using low CPU multipliers (Im currently at x14) I would be able to test the BCLK and QPI maximums. Im probably missing something though :yepp:
some chips only scale well under cold for BCLK. This one won't go past 230 on air.
http://valid.canardpc.com/show_oc.php?id=553271 clean validation this time
another 1m
http://img18.imageshack.us/img18/4333/1m8047.png
getting close to cracking under the 8 sec mark :)
also hitting over 240 BCLK is amazing :D
5G's 32m, untweaked.
http://img7.imageshack.us/img7/4690/32m735.png
Wow. Amazing approach^^. :up:
That little d0-b4st4rd goes like hell with the classified! :D
Thx SAE, 1 more http://img13.imageshack.us/img13/451/32m731.png
after Ive been through the learning curve with tis chip I might go looking for one of your batch :D
yup 38xxBxxx batches seem to be a bit better than A batches

The BIOS is beta status - not public yet. As soon as EVGA approves after full in-house trials they'll go public with it.
regards
Raja
are there any good changes with this Bios version?Quote:

THe newer BIOS adds Dram Vref and also individual RTL control per memory channel.
On the template front there's not much to say, 103 PCi/e will get you upto 230. Over 230 you need a minimum 108, 110 will push past 240 BCLK if your CPU is capable.
The only 3 voltages you need to wrry about vary so wildly from CPU to CPU that it's almost impssible to use the settings of one on another (Vcore, VTT and VDimm) and expect the same results. Play with CPU Impedance and QPI Comp for stability at high BCLK, again this varies according to the IOH and your CPU.
later
Raja
ahhh so I need to mess with the PCIE freq too?
Might have to take a look at that cause I am otherwise limited at 4.65G
http://i239.photobucket.com/albums/f...dation_web.jpg
http://valid.canardpc.com/show_oc.php?id=553958
Yes you do need to offset PCI/e. Make sure you do it from BIOS to create the offset necessary during the boot cycle to create BCLK headroom within the OS.
Many many thanks to you raju. I upped the PCIE speed and the CPU just took off :D
http://i239.photobucket.com/albums/f...dation_web.jpg
http://valid.canardpc.com/show_oc.php?id=553974
No probs, you should be able to bench upto 240 quit easily, and possibly even better the stuff I did. There's nothing to it really.
Nice Chip M8 :up:Quote:

Thank you for help i´ve put the PCI/e to 101 for 220 BCLK. i´m priming now but i cannot run the 221 bclk. these are my settings at the momentQuote:

If running a D0, you should have plenty of overhead to scale on the 21x multi without chasing 221X19 for 24/7. I'd use the 21X multi and start off with 200 BCLK. I bet you can run 4.2GHz with around 1.24V load Vcore too.
later
Raja
yes i can. I only test the BCLK at the moment. Look BCLK 221 seams to run at the momentQuote:

This validation used only 1.425 vCore and the CPU is Batch# 3849A837
Try setting it like 102-104 :up:Quote:

Thx to OPB for the tips. Not maxxed out yet, but getting better...
244?! it's incredible...this board really rocks ;)
congrats man! ;)
Astonishing run there Raja :up: Congratulations, keep it up buddy ;)
keep pushing it
Come one, "smack that :banana::banana::banana::banana::banana:"
Nice results;)
Impressive raju :up:
Started playing bclk game here meself tonight. 2/8 divider and 8-8-8 seems to be the sweetspot, exact same settings cannot boot 2/6 9-9-9 :confused: Multi 19 max for now, 20+1 is a lot harder. On air. VTT can be lowerd. Any tips ? :D

Probably needs to be cold to really scale..
254BLCK... :eek:
what are you tweaking to hit these kind of levels raju? Im not getting as much time to play around with my bench setup as I wish I was this week :(
Dude what cooling did you use ?Quote:

are you using sub zero for the mobo also? how is it possible to make bclk scream like that??
Board is cooled by ambient air only - room temp 16 Celsius. Just the CPU on cascade.

Raja
very nice,
could you post the trick you gave to OPB ?
congrats, raja, really impressive, I am still in 241.6 bclk, really need more cooling....:)Quote:
