**Official DFI LanParty UT P35-T2R Review/Overclock/Guide Thread**

1412 has been update for the DDR3 UT board. It's still a work in progress as a couple of the voltages appear to be misreported.

[cantankerous]

Thanks for the reply Praz. Is the misreported voltages only for the DDR3 board or across all boards as a whole? I ask due to my misreported Vdimm, however it had done this before I even installed 1412 as I using 1408 when I first noticed it. I also went back to 1403 and same thing. Don't have a clue. So far that is the only issue and I am running memtest now to be sure things are still stable. I hope nothing comes worse of this with my Vdimm no longer being able to keep at its setting and it just keeps rising, rising, rising. My Ballistix are the original double sided ones and I am VERY LUCKY to have them still running as well as they are with how easily they seem to die. I would hate for them to be fried by high voltage when I didn't even set it myself to do that.

One idea I thought of is the temps have drastically risen with summer being here. Ambients are way up as is humidity. Is it plausible that perhaps the chip that controls the amount of Vdimm going to my sticks has become slightly unstable due to heat, or perhaps it is just the monitoring chip that is out of wack. If anyone of this has to do with heat period, I dunno.

I am not one to put a DMM to my board while running so unfortunately I can't check, but am wondering if there really is more Vdimm going to my board than I have set or if it is giving the same amount as always but it is only the reporting that is wrong.

[Praz]

Don't know about other boards. I did a quick run last night to verify everything was listed. On the DDR3 board reported VDIMM is 0.03 - 0.04 lower then what is reported by Smart Guardian and BIOS. I'm going to do actual voltage measurements tonight.

[cantankerous]

Ok thanks. I wish mine was lower, as instead it is higher. Higher = death to chips where as lower simply means instability. Please do share your findings on idle/load on Vdimm set in bios compared to what Everest is reporting.

Looking forward to the readings. I need to get my DMM out and stop looking at these softwares. Or at least calibrate my readings every time I update the apps.

I posted this in the info and support area, but I'll post it here too.

So I broke down and bought a Prelude, but when I put it in the PCI slot it wasn't detected. The light turned on showing it had power, but it didn't show in the boot list of items, nor does windows detect it. The thought crossed my mind that I had gotten a dead card, so I tried another PCI sound card (old crappy one), and it too wasn't detected. I found an old PCI network card... not worky there too.

I have tried different combinations of enabled and disable options that could deal with the PCI bus, but nothing so far has allowed me to have anything detected on the PCI bus. My google-fu is failing me, as I cannot find anyone else with this problem. I may be missing something simple and stupid, but after an hour of rebooting, I'm not sure what is left for me to try.

If you have any idea on why I can't see the PCI devices, please help me out.

Thanks,
WoZZeR

[cantankerous]

Did you try a different PCI slot? It sounds like you were determined to keep trying the same one. Perhaps that one port is unfortunately dead. Something definitely seems odd if nothing that you put in that slot gets recognized.

Are you on the latest bios?

[WoZZeR999]

I tried all 3 slots, I tried the latest stable and latest beta bios. The cards receive power, but are not seen.

[cantankerous]

Very odd. Did you try on a fresh format?

[WoZZeR999]

I had not tried on a fresh format, but what concerns me is that it's not shown on the PCI device list.

I am getting Random restarts for the past 5 days. I have replaced everything but the Video card, PS and the MB(DFI P35-T2RS ). It happens while I am surfing the net or playing a little TF2. I bought a new HD and did a complete reformat and it still did it. My gut tells me it is the New Enermax pro82+ 625w I bought. Have any of you had this issue with DFI P35-T2RS? I ahve included some pics. Maybe you can see somthing I can`t.
Thanks for your time

I think your "gut" feeling is right. Traditionaly Enermax psu's and DFI's have not played well together at all. A look at something else would be a good idea. OCZ or PCP+C would be a good place to start.

[haoster]

i just bought one yesterday. had some brief test.
now i can get core 0 stable with my old settings on p5k-premium, but core 1 fails after 2-5 mins everytime...
i have vtt=1.3v, cpu gtl ref=64 for both, and nb gtl ref=61. cpu is a 45nm e8400. 4.18g(465x9) at 1.376v in cpu-z, nb=1.41v

anyone have any suggestions? maybe play with the cpu gtl ref?

With an E8400 the board should do 465FSB without the need of adjusting GLTREF voltages.

i can boot up 600fsbx6, with 1.6v vnb...
but, 465-470, the 2nd core just wont be stable...

Hey guys. Something odd going on here that hopefully someone can shed some light on. It has been many months since I bothered tweaking with the bios since I have it pretty much set where I want it for 24/7 use. I have had the 3/16 bios flashed since its release and have not changed it. I currently, and have always had my Vdimm in bios set to 2.00v. This has ALWAYS read between 1.89-1.90v in software readouts such as Everest. The past week or so I noticed the reading was up to 1.92v which I found odd. Just checking now it is reading 1.94v. It is clearly going up and I have no clue why. The second jump to 1.94 is what prompted me to hopefully get an answer on it. I understand it is only a software reading and should be taken as so but with months of it reading 1.90v, why is it now reading 1.92-1.94? What would cause this to happen. I am worried something may be wrong and at some point it may shoot like 2.5v through my ram and fry it without me even knowing.

Hopefully someone can shed some light. I am using latest Everest 4.50.1408.

Yes I am quoting myself but I feel it is important with what I have to share.

I fully believe this is heat related now. For days it was quite hot and the voltage ranged anywhere from 1.92-1.94, sometimes hitting as high as 1.95v when under heavy use. This was all being monitored through Everest. With many different betas being released over the past few days I tried them all with the same results. Rebooting into the bios and checking voltages there showed similar results in the way the voltage was scaling.

This morning temps have really dropped outside. I opened my window and checking about 30 mins later I now noticed it was reading at 1.90v just as it should. I kept my eye on it for a good couple minutes and it never fluctuated. While Everest was reading 1.92v booting into the bios would show 1.98v if set to 2.00v. While I am reading 1.90v in Everest now I rebooted into the bios and it showed 1.96v which explains the scaling I mentioned above. .02v in Everest is .02v in bios. So now that I know it is heat related should I be overly concerned? It seems either the voltage regulators, or the sensor itself is having a hard time tracking tightly/accurately when running above a certain temperature. Whether this is something to be concerned about I don't know. Do you? Lastly I am wondering. Is it my RAM itself drawing more power if unstable due to heat or is the board itself throwing more voltage to my RAM due to the instability while under heat. Is it even throwing more voltage at all or is this just the sensor read out? Either way what on the board should be cooled when ambient temps are up to keep voltages and reading at what they should be. I have never noticed this in the 9 months I had this board until the very hot weather here last week. It is definitely ram related however as regardless of heat my Vcore, NB, VTT and PSU rails were all reading what they should and have been for previous months without falter. Just want to be sure I am maintaining my system as should so I have no premature deaths on my parts. System is running quite well so would like to do upgrades for the sakes of upgrades, not buying new parts to act as replacements. I am going to get some canned air and do a real good cleaning as I know it is quite dusty in my case. Shouldn't hurt even if it does no good.

Thanks for reading my long winded chatter.

[Praz]

Right upper corner of the board where the small silver heatsink is near the last memory slot. Try some air movement in that area. There is an additional FET on the backside of the board that because of ambient temperature may be heating up and causing thermal drift.

[cantankerous]

Gotcha. I had a look at my board after writing my last post and that wast he very area I figured would need the cooling. The silver sink gave it away. I figured since it was a ram issue that the problem must lie near the ram. I can't see the regulator for the ram being too far away from the dimms themselves.

Is it common for heat to cause voltage drifts to a component? I have never once heard of this on any build which have always lived in this room in my house which does get particularly hot. For whatever reason this board now is particularly sensitive to it when it comes to VDIMM. It could just be my personal board and not the DFI's as a whole. Is this something I should be worried about? Is it a risk for something to die? Something I should be worried about? I have an Antec Spot Cool over my ram now that was running at high, but recently down to low as I have been having issues with my ears lately and wanted to quiet down my systems racket. I will try and turn it back up and see if it helps.

Thanks again for the response.

should i trust the voltage reading in bios(1.287v for cpu, 2.07v for ram) or the one in cpuz, smartguardian and everest(1.31v for cpu, 2.03v for ram)

no dont trust bios readin everest is better

[haoster]

no dont trust bios readin everest is better

so the 4 sticks in your sig running at 1200mhz at 2.05v is the reading in smartguardian and everest? more like 2.1-2.15v in bios?
i am scared to add more because the readings in bios are so high

i always talkin real volts dont look in bios readings everest in 99% acurate
the readings you see in everest actual might be -0.01
i always measure my volts with dmm

Hello guys,

Just wanted to see if you could achieve my goal/dream

Q6600 L737A 1.275 Vid
G.Skill 2 x 2 GB DDR2 800mhz

All I want to do is 9 x 400 and I would be a happy camper

If you guys could post/reccomed some settings with simular ram ( I know I am not the only one with this type of ram and cpu ) that would be great and I guess I could work from there.

ATM I have it at 8 x 400 and its been fine for couple of months now.

[mad_skills]

Hi guys, need some assistance, been out of the game for a month or so...
Have a 12/24 bios on my UT so can anyone tell me, i'm a bit lazy to dig through last 50 pages, any new bios that brings some improvement for 65nm cpu's? So far i've tracked 'till February or March and i've seen no need to update, seems like all these new bioses are meant to improve Wolfdales, so anyone can tell me if something from April/May/June is good for 65nm i would appreciate it.

[cantankerous]

I found 3/17 MUCH better than 12/24 for stability. It has a good amount of new features to tweak as well. Been on 3/17 since first day of release and have zero issues whatsoever. 12/24 was good when it was out but 3/17 imo is a much better bios.
