I've recieved it today. It's a brand new, unsealed DFI LP DK P35-T2RS sample. :D

AFAIK actual one is the high-end version. The T2RS is built with solid Japanese capacitors.

This board is a piece of gold!! :D Truely one of the best I've ever tested with a QX9650. What an FSB killer! :shocked:

I've tested several boards so far and sometimes felt it a bit monochrome as differencies weren't very clear. But things are clear with the DFI LP DK P35-T2RS. Difference is real. :p:

Check this figure to compare.

Just amazing... :eek:

So; I'm not yet fully confident with the board. BTW, I've started playing with it under cold. As I've said already, FSB was the first good point; then the second was CPU temperature monitoring... Yeah, the temperature as shown by speedfan or the bios, looks very accurate even at about -120C. :D

Nothing is perfect... :shrug: And obviously, the DK P35 isn't. The voltages aren't very good on this one. I mean, CPU core set to AUTO+0.785v corresponds to 'only' 1.81v actual; same matter with vDDR... 2.50v bios is in fact 2.39v actual.

woah nice Bertha has the powa :D

Yeah DFI digital pwm makes selecting right vcore pretty hard.

Good news and very nice ... i ordered one few days ago !
Seems to be a good choice ;)

i need this motherboard

first, combine for my nick name
second, mi p5n e sli sucks!

Congratz Bro !!! impressive little P35 :)

I think the bios isn't good for the Vcore (same problem with the LP P35 with you) you need the futur bios for the true value for the vcore :)

Awesome results!! Now i understand why people love DFI so much.

Maybe i´m getting one to verify that kind of power by myself. ;)

Wow man, this mobo is really awesome!

Hope my TR2 arrive soon...it's in customs for 3 days now :shakes:

Rbs.
:wave:

Nice test! I it is nice to see, that this board is one of the best.

Did you test it with an E8500? I use this combo, but the FSB limitated :(

She is better than the DFI LanParty P35 ?

Great score ;)

Thanks guys! :toast:

Hum; ok I see. :) I've to figure out a vDROOP mod; I can't bench very high because of that crappy vCORE. It fluctuates a lot; and worstly at high skies.

It is! I'm pretty sure you'll appreciate it buddy. :)

You may be right bro. Anyway; I think a simple vDROOP mod would benefit the stabilty a lot.

I don't have a Wolfdale to test. Sorry. What's your max FSB?

You mean the UT LP version, right? So, Yes, it looks like better to me. :)

great results before, ill be sure to pump that thing when my e8400 finally arrives. it seems to be a real great board for the money, it costs around 120euros in germany

Great score Before
i love petite bertha

great FSB-Clocks mate , this is my next investment.

Sweet clocks there !

Thanks guys :toast:

Max FSB so far was 511... Corrupted validation :shrug: Anyway, that's not bad for a CPU which was stuck at about 480FSB on previous boards. :yepp:

Next step will be under the Fat Bertha... :p:

1.83v is your max possibilité of vcore , or you had not test more ?

And what about the memory clocking on this board ?

Have you test others cpus under it ?

I was wondering when this board would be tested/released? A while back windwithme tested the regular DK version (the one available now) and mentioned the more expensive versions (all solid caps, etc...) but he did mention any release dates. Anyway great review and thanks for sharing your results before, much apprecaited!

Wow...where can I get this board on the US????

ps..@0cool Jessica Alba c'est trés precieux:P!!!!!

NewEgg has this board for $135 IIRC.

Thanks guys! :toast:

vCORE is a real matter. Looks like all settings from AUTO+0.700v to +0.785v don't make a clear difference. Additionnally, vDROOP is awfully HUGE! I've to find a vDROOP mod ASAP. Too bad there isn't a voltage damper option in the bios. It would be a great addition.

Didn't try memory clocking too much. Anyway, the board seems to doesn't like tRFC (might be something like that the tighter the PL = the higher the tREF)... and can't say anything else ATM.

I've only tried it with actual QX9650... and will try it with a golden C738 QX9650 (one of K.J.'s) :p: I want mid-500FSB validated. :D

Thanks ;)

I've asked my contact at DFI about availability. I'll let you know.

I cant reach a higher FSB than 520Mhz :(

Which cooling?

wow you tried DFI X38 LT or P35-T2R as well ? they don't seem to have bad a vdroop as the DK P35 ???? Or quad core QX9650 a factor ?

@Roger_D25

in Poland it's available from about 1 month, but users didn't observe any advantage with all solid caps :p:

Power phase are different on DARK , and it seems to vdrop like Blood iron.

Eva, you need the droop man with 45nm, having no droop is worse than bad droop with these CPU's

weird... my E8500 Q740A493T seem to clock higher and more stable with less droop on Asus Blitz Formula and helps on Asus Commando too passing 32M @5155Mhz on 1/4HP SS :)

550FSB under water is pretty good actually. Did you try it under cold?

How does droop help OCing? Or maybe I'm thinking about this in the wrong way...

It was 520Mhz.... not 550Mhz. No, only water at the moment.

No, what settings should i take? Do you have a little tip for me :)

Ok, my bad :)

When you find a Vdrop MOD, can you post here ? :up:

I have 0.048v Drop with my Q6600 :rofl:

Uh, so is Tony or anyone else going to help explain why droop is a good thing for 45nm? I got the LT believing that the droop control would be a benefit :(

nice diagramm about the fsb (pretty awesome how it performs) and some nice clocks. if i wouldn't mind dfi due to personal experiences i maybe would consider benching it ;)

Excellent article on Anandtech.

On the flipside, some other people's thoughts.

Ah ok. Well I suppose being able to turn it on and off is a nice option to have then haha. Another weekend of no overclocking though...must join the e8400 hoard soon.

I've changed the chip for a C738A which is a little better at 500FSB+.

The board definitely doesn't like tRFC tighter than 30... a bit high IMHO. Nevermind, the Spi32M is pretty fast for 5292MHz and 512MBx2 DDR2. Will try with 2x1024MB tomorrow. :)

If I understand correctly this matter, I'd say, vDROOP is still the ennemy of overclocking; at least extreme overclocking.

Ok, eliminating vDROOP causes VID to become useless and peak voltage to exeeds VID value; but who cares? :shrug:

I can confirm this as well... :D
Had all kinds of weird random errors for weeks with low tRFCs... :shakes:
