DFI JR P45-T2RS Engineering Sample

[NormanABates]

nice mobo, monster matx.

does anybody know when will the ddr3 version be released?

[TheScavenger]

I am so excited for these new Jr. boards. I am trying to force myself to wait for the DDR3 version (which I think is due in September). If Asus doesn't come out with something comparable then I am definitely going DFI.

Benchmarks please

[MassiveOverkill]

Can we get an update? A couple of guys over at [H]ardForum got this board and can't get much past 400 FSB. Of course they have the released version and not Engineering samples.

Nice to test Johnny............. long time no see............

@MassiveOverkill : how about this one ....................... FSB 685

Massive is most likely looking for realistic results, With a 11 August date that submission was most likely done in the lab. What could that mean? All kinds of possibilities. Subzero cooling, handpicked components, custom board most likely tuned with a scope. Lab results mean little if they can't be duplicated by the end user.

[Johnny Bravo]

Couple of results up

[Eldonko]

Nice JB, did you test the top end fsb or is 600 about it? I see you have some more voltage space

[Johnny Bravo]

very much just a case if aiming for a round number I believe 685MHz has been hit in house at DFI - I'm just using air cooling

Yes, JR P45 Micro ATX board has “2 PCIe v2 x16 slots” , due to our SPEC. definition for it, we fixed 2 slot are 8X+8X supported.

Due to the design limitation, there is no jumper array or digital switch to let PCIE1 become 16X supported



But, do not worry about the 3D performance. We believed there is no a bigger performance gap between 8X/16 Gen2, even CF enabled.

Picture is the test we done on ATI 4850 for your reference (DK P45 compare to LT X38)

Have a nice day!

So, fixed at 8x full time, but they claim there's little to no performance hit for this...

[MassiveOverkill]

Thanks for the update. Shortly after I made my last post, one of the guys was able to hit 500FSB on his Core2Duo.

Ok, that does it for me. I was thinking of try this thing out but now I've decided not to.

Why in heavens do they cripple the board like that? And where are the quad results?

Cost savings, must be.

They really cut costs on their DK budget series from what I can see. Anyway, if you are going to do CF, it makes no diff cos P45 is 8x8 limited anyway so I am still getting one - there is no other competing mATX mobo for CF presently.

Yeah good people, let's see some quad results pls.

Nice fsb!

So as i understand it, both slots are fixed at 8x, whether single card or crossfire? If so, will 8x cripple/bottleneck the latest cards? I'd be running one 4870.

[Shadowtester]

I really hope to see some OC results with a quad soon really looking forward to a matx for gaming and currently this looks like the best bet.

Q9550 ES E0-Stepping - Batch L816A850 - 500MHz FSB - 4,25GHz @ 1,376V @ DFI LANparty JR P45-T2RS



Any beta BIOS available? Or Smartguardian in the JR-Edition?

Nice result Chebu! I can't wait to get mine.

This board keeps looking better and better

Great overclock!

[Shadowtester]

Just got mine yesterday from Newegg looking forward to putting my Q6600 G0 on it over the weekend and seeing what I kind of OC I can achieve. I also have a pair of Nvidia 8800gts 512 that will be filling the 2 pcie X8 slots and 4gig G.Skill 1066 ram going to be a busy weekend

Are you going to run dual monitors? The board does not support SLI.

[Shadowtester]

Actually I am going to be using the second card when I am folding for the most part the gaming I do a single 8800 gts will do the job fine.

[G80]

Probably my next board also. Good that they pay attention to the other form factors aswell, ATX is big and boring lol

Sounds like a winner.

[Nanometer]

what voltages are you using to hit that fsb?

[Ice009]

Thanks for the pics.

I do hope DFI doesn't go down now that Foxconn have bought some of the minds . This and the new DK revisions are fantastic signs.

Which DK revisions are you referring to?
