@ DemonEyez : How can u get that kind of temperatures from Chipset ( 34* ) couse i have the same board lets say and with 1.28 NB voltage i get like 50*++.

[C-N]

So I'm guessing the board isn't locking the pcie properly?

I never did get to the bottom of it, I tried to work it out nobody could help so I just accepted it & lowered the frequency. I ran 125mhz ish & dropped it down to 115 ish.

Nice! It would be interesting to see what kind of bandwidth and latency you get in Everest.

I am at work atm but off the top of my head I get 10650 across the board & 48~49ns latency. I'll post the screen up when I get home.

On the 266 strap I have to drop the cross setting back to relaxed to run Orthos stable otherwise the Bandwidth is about 10850mbs & 47ns latency again I'll post it up later.

Right now I'm running Orthos for 1.5 hours stable with your settings at 9x500. vNB is 1.41v right now, I have to do some further testing and see if I can lower it.

Looks like I'll be getting a Plus then what have you set in BIOS to get 1.4 in SG?

Anybody noticed these on DFI JR P45 with the 10/07 bios?

This is what "P_1" is referring to but I don't think he has the JR.

OT

C-N : Mine appears good and solid

tasmashumi : Good to you mate

Captain slow here just got the joke

Lowering voltage on NB is a good thought. I'm looking forward for results

>

Just did some tests, I loose stability when lowering vNB and keeping those timings tight. Prime/Orthos fails after 4 hours.
So it seems that 1.40v is the minimum voltage required for those tight settings with my board

I'll revert back to looser NB timings and lower NB voltage (1.31v) for 24/7 use. Running with those tight NB timings and Performance Level only differs 300MB/s in Everest Read Bandwith and 3ns in latency.
In my opinion the 0.1v increase needed for that is far too much and not worth it for daily use.

I run with a Swiftech MCW30 waterblock on it.

thanks for the updates.

it seems that these DFI P45 boards are more with lower voltages & tighter timings

Those are some nice numbers for bandwith and latency. Just for the fun of it i'll try 266 strap this evening

Seems the Plus does have the better chips and does run with less voltage

The board undervolt a bit. I have to set 1.445v in Bios to get 1.40v in SG.
Same goes with vTT. 1.33v set in Bios gives 1.30 in SG.
But those voltages are rock solid, no fluctuations whatsoever

I wouldn't rely on SG/Software to be any where near accurate, I don't think I've had a DFI yet that displayed DMM voltages in SG/Software.
I may have to sit down & work out the read points on the weekend coz not knowing is killing me.

Here's the 266 strap screen shot with more aggressive & fast.
Haven't managed to get this properly Orthos stable yet & tbh I don't think I can do it either but I ain't finished yet

I just tried to boot with the 266 strap , using the same settings as you did but my board refuses to boot. The only thing I get out of it is a nice C1 error, and a message that there's some error with the bios bootblock.
I've never seen such a message and do not hope to see it again. So I'm not trying the 266 strap again.
Seems that although you don't have a Plus board , you got a golden one

For Orthos or Prime to be stable you'll need more volts on the NB is my best guess, and perhaps some NB GTL tweaking?
Would be really great to see those timings stable. That are some wicked latencies

I think you could be right but I cant get any more than 1.55/57 (set in BIOS) to run, it just locks up in Orthos. NB, GTL's & vref are all tweaked out. I have only just scratched the surface with CPU skew control & done nothing with dram skew so theres hope yet.

This is weird, for ahci to work I have to enable the jmicron controller... Otherwise it just won't find any devices, even though the ahci screen shows that my hdd and dvdrw are present.

This is currently an issue with the DK X48, P45 and JR P45 boards.

I just find out my real problem about nb core, it's because my gfx card (ASUS EN8800GT Glaciator) I cant run to my windows with 1.4 nb core after I removed nvidia card driver but after I installed nvidia card driver, it's starting hang on that even after restart

maybe I gotta find other card for this

any 8800GT user's in this forum can boot after nbcore 1.4 pls tell me, at least I must just change the manufacter of this card (to like XFX, Winfast or somethin), thanks

bios can't help, even with latest 10.03

[dz`]

I have XFX 8800GT which I bought on 8800GT release date. Board refuses to POST above NB Core 1.3700v in BIOS. I'm hoping that 1.37v should be enough for a modest OC of 500FSB*9 with either 1:1 or 5:6 FSB : DRAM

hey thanks for telling me that over at DFI street praz,, i am loosing my f'ing mind over this piece of crap P45 JR...
i order my T2RSB Plus tommorrow.
screw P45 i am going back to X48

[GaS]

screw P45 i am going back to X48

That's what I think of, if they not modify the BIOS for GX2 support.

any 8800GT user's in this forum can boot after nbcore 1.4 pls tell me

I'm currently using Inno3D 8800GT(OC version) and didn't find any issue no matter what VNB i change. BTW, you not need other card, try to flash newer BIOS for 8800GT. The most of these cards has reference design and only BIOSes and memory different.

using XFX 8800GT...no problems above 1.4v for NB

[SEPTH]

thanks all of you, now I'm gonna try flashing bios, if it's not work, maybe I'll change to XFX or something

[tamashumi]

I'm now stable on 9x450. Nothing special but this is kinda OC and far better that I could get on non-plus board. I haven't tried higher yet. First gona tune voltages to minimum required for stable work at this frequency. I let you know

@ DemonEyez : How can u get that kind of temperatures from Chipset ( 34* ) couse i have the same board lets say and with 1.28 NB voltage i get like 50*++.

Ofc the answer was a water block, but you could also check how NB cooler fits and maybe change thermal compound. Do you have plus version? Mine plus is like 10-15C cooler then previous non-plus on the same voltage.

Captain slow here just got the joke

Looks like I'll be getting a Plus then what have you set in BIOS to get 1.4 in SG?

Hehe I ment exactly the same what DemonEyez said (quoted below). Maybe you should not raplace it. Are you still going to?

I see you test stability quite hardly. My tests are for now rather briefly. But when I get some WC kit and higher frequencies then I do longer test runs.
Agree that for everyday use one doesn't have to squiz out all juice in a risk of damaging its rig.

But those voltages are rock solid, no fluctuations whatsoever

This is EXACTLY what I observed (and posted before). On non-plus voltages are varying and NB needs more V (at least set in bios).
Have I mist something, did you change your board from non-plus to plus version too?

This is weird, for ahci to work I have to enable the jmicron controller... Otherwise it just won't find any devices, even though the ahci screen shows that my hdd and dvdrw are present.

Damn weird, as you know I had troubles with sata controllers on this board already. This is another thing I observed. Stupid design idea or a bug :/
One more thing to mention to get SSD OCZ working with this board, BIOS has to be 10.03 and SATA controller needs to be in RAID/AHCI mode (with normal 7200rpm drive or non-plus version it isn't necessary).



What are those GTLs? But please do not paste me a link with specific technical details for couple of hours reading.
I gona to find and read something like that sooner or later ;]
For now I just need to know shortly common sense of this setting and what gives its value change.

I still don't think there actually is any difference once you push the board fairly hard I think you will need all the NB voltage you can get. I have no doubt there are good & bad boards but I don't think I have a golden board I think the people that have had bad experiences probably just got unlucky or as I see quite a bit there hardware didn't play nice with the picky DFI.

I have seen a couple of people using 1.5v + on the NB with the JR, STD & Plus boards with both the A2 & A3 revision of the chipset.

I too can run high fsb on tiny NB voltage but you have to back the performance off so far my Casio calculator would win a race

If I find clear evidence the Plus board with the A3 chipset is better than the non plus A2 board I will order one but atm even though my P45 is running nice my P35 still keeps up with it no problem.

[cole2109]

My did 610FSB with 1.38-1.39V on NB...

[dark22]

which is the best bios for t2rs (not the plus) paired with a q6600?

.

I call my system stable only when it has run Orthos or Prime for at least 8 hours. Normally I let it Prime all night and see the results in the morning. Finding the right settings can take up a lot of time in the beginning, but once found i don't change it anymore and use it untill I sell the board for a different better one.

I have the Plus version the beginning. Never had the non-plus. I was comparing my board with C-N's I can do his timings with less voltage (only not the 266 strap)

[tamashumi]

@DemonEyez
I like "rock" stable myself. OCing for just give a try single run of SuperPi or 3dMark hoping that maybe it won't crash till the end of benchmarking and later spanking a monkey over the result really sux
For now I have many different settings to check, so tests have to be shorter. When I reach desired OC then I run some priming over a night (or day when I'm out of home).
Btw. you're welocme to try my test procedure for fast tests (f.e. when new board comes). SuperPi 32M up to the result while Priming with large FFTs single thread. It's heavy demanding, not much can affect stability if this one pass.
Which Prime preset do you use for testing?

Which 'performance' option do you mean?

which is the best bios for t2rs (not the plus) paired with a q6600?

Don't know about quad cores but I recommend 08.12 bios, latest non-beta.
I had no difference between 08.12 and 10.03 (latest beta) on non-plus board. Which cannot be said about plus version (for which I would recommend 10.03).

[Bullet92]

What about max FSB at non-plus version?
I've just got one, not installed yet but looking at "her"
