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

Hoping someone can sort me out with an answer on this. When dealing with parameters such as memory timings, and more importantly Read delay phase adjust/TRD Phase adjust settings, do these settings directly rely on the memory itself being able to keep up, or is more of a chipset dependability for stability when adjusting these settings? I am sure the memory has to keep be able to keep up but I am seriously thinking the chipset has more of an impact unless someone can tell me otherwise. The reason I ask is this. After many, many lost days due to issues with prime failing I copied the Anandtech article settings quite closely and achieved some success, however, they are using settings that just don't agree well with me at all. At 445 x 7 I can run prime for up to 10 hours as long as sub timings and TRD Phase adjust settings are left at auto. If I try and change any of these, even slightly, I will fail prime, even if it still isn't as aggressive as others have set them with more voltage to boot. I am trying to narrow down the problem so I can solve it but I am wondering if I am wasting time assuming it is on particular part of my setup when it could be something else completely different. Raising volts does squat and I am really hating tuning the GTL's to their ultra sensitivity when being fooled with. My TFRC is 42 default, most have theirs down to 30 to gain some bandwidth without problems yet I can't even do 40 without prime failing. The TRD Phase adjust settings were adjusted just like the article suggested with all set to auto except one on channel two to allow 'breathing space' for the chipset yet it still fails prime. I would really like to get more from my system though it seems 445 is about max without having to go crazy on the volts which makes my already hot temps even hotter. Cpu is at 1.325 in bios, VTT at 1.60 and chipset at 1.61. My GTL's are 115/114/117. If anyone has an idea what is going on please sort a brother out before I punch this thing and give up. I am loving this setup but its not a smooth ride at all for me. Rest of parts are as sig lists. Sorry for being long.

Thanks for all your help guys!!!

Turtle ;)

Edit: Looped up the GTX and it is fine. Really weird... I honestly think it was the 4 pin floppy connector that got me going :)

The nice thing about having DFI experience under your belt is to expect the unexpected :D

Hey Damon! Glad to see it finally post for you.

I'm confused regarding the 4 pin floppy connector ? Can you elaborate

Thanks

the old expression "your milage may vary" is about all I can say, every board has it's differences as does each stick of ram. you just need to find a "sweet spot" and make minor adjustments from there. other peoples settings are great for them but may not work at all for you.

Are you referring to these ? If so, what was the issue ?

http://aycu16.webshots.com/image/327...6664197_rs.jpg

I honestly dont know what did it. I think it had to do with getting my GTX out (it was bought around launch), getting the 4 pin power connected, waiting for hang, pressing the EZ reset button, and some voodoo love.

I honestly dont know what really did it. But I am glad it happened :D

Thanks for all the help guys ;)

You flash Bios yet? 9/13/07 is infinitely better and more stable than 8/10/07

10/ 05 beta ftw.

For me the Read delay phase adjusts just help you tweak out your setup, theres no need to play with them (leave them on auto) until you have everything else where you want it.

The Read delay phase adjusts help you run in between performance levels, For example with the early BIOS's my rigs ram run with Read delay phase adjusts all on auto Orthos stable @ 1140mhz performance level 7 using the 333/800 divider @ 475 x 8. It would not run if you alter any of the read delay phases. Now if I then changed the ram divider to 266/667 which boosted my ram speed to 1190mhz I found I lost some performance as the 266/667 divider by default runs performance level 6. What I then did was enabled some or all of the Read delay phases to try to run in between PL6 & 7.

I think it was the 1005 or 1019 BETA BIOS that finally let me run all the read delay phases enabled. I later found out my RAM would run PL6 @ 1190mhz with these BIOS's too.

I have played for days with GTL tuning & come to the conclusion (& I am going to be slammed for it) that GTL's although they have a profound effect on stability are an un necessary waste of time. It may just be my setup but I seriously doubt it. If you just switch your "GTL+ Buffers Strength" from default strong to weak then leave the "GTL Ref Voltage Control" disabled you like me will probably be able to make 450-480 x 8 Orthos stable.

GTL tweaking is however vital particularly for the NB to stability when benching/running on the edge.

I would also up the vcore a touch just to be on the safe side & loose 2GB of ram until you get it stable.

CN :)

P.S for those of you that disagree please say so & why but don't all shoot at once.

Thanks a ton C-N for your replies. I have always looked forward to reading what you have to say as it is always knowledgeable and accurate. Thanks for taking the time to sort me out. I was anxious to get the Read Phase Delay working as the article stated it worked for them up to 1125mhz on their 4GB kit with a quad core so I figured it should work for me but it doesn't. I will leave it be for now. I too am getting a little frustrated with the GTL tuning and will definitely be trying out your strong to weak switch and disabling the GTL's to see what I come up with as that is something I haven't tried as of yet. Have you had any luck lowering any of the sub timings, primarily TRFC for some extra performance and if so how low were you able to go. I am going to continue to test here on my own but do like to see what others have come up with on their setups. So far mine doesn't play anywhere near like others are mentioning. YMMV is an understatement on my particular system but in that comes the joy (or curse) of using this board.

Thanks again bud, much appreciated.

Unless I'm not reading correctly the whole Performance Level/Read Delay as written is ass-backwards. The lower numerically the Performance Level is set the higher the performance. Setting the Read Delay to enabled give a -1. Such that if the Performance Level was set at 7 and all Read Delays were set to Enabled, from a practical standpoint, the board would be running at a performance Level of 6 (higher performance).

GTL adjustment is more then a means of stability. Pinned to their optimal setpoint the overclock will require less VCORE, VTT, NB and memory voltage. For the brute-force approach a person is best off to ignore GTL tuning and concentrate on voltages.

I am quite sure you will get there I just hate to see people getting too caught up in what others peoples rigs can do to the point they lose it with their own.

You have to work stuff out for yourself with your equipment & although you may be able to find a ton of different specs try to look for the common ground among them & use this info as a guide not the answer.

This DFI LP P35 is undeniably the most fun board I have had for years I love it & I am sure yours will earn your respect too.

My TRFC is @ 26 for 24/7 use & it will run down to 23/24 @ 1200 for benching but its a tad sketchy down that low.

Here are my specs/setting for your reference.

PRIME95 + 3DMARK2001SE + 3x CPU-Z:(SCORE 64156)

http://i106.photobucket.com/albums/m...S/3DMARK01.jpg

Awesome, thanks again. I will surely keep what you have said in mind. Believe me, it hurts me to come in here whining for answers, but I feel if I truly am stumped, I do need to ask for help once in a while. I surely will keep up on this thing as I am just about 8h prime stable on my current settings, so I at least have something stable to work from. Temps are very hot in this room so I cannot see myself getting my cpu any higher than the 3.1-3.2ghz mark so with cpu clocks/temps pinned at what they are I just want to squeeze every last bit of performance I can from the other parts without any additional voltage which will only cause more heat in the end.

I currently have the PAtriot PC-8500 memory in 2 x 1 GB modules, and find it a bit difficult to get stable at its stated 1066 MHz (533 x 2) frequencies. I remember having read that the Micron D9 GKX chips used in these modules are less overclockable than their D9 GHX counterparts, and am considering buying new memory to go with my new Intel Xeon X6085 CPU.

Memories I am currently considering are:

Crucal Ballistic PC-8500 2 x 1 GB
Kingston HyperX PC-9600 2 x 1 GB
OCZ Flex XLC PC2-9200 2 X 1GB
OCZ Flex XLC PC2-9600 2 X 1GB

The Crucial and Kingston memories are the low cost alternatives, while the OCZ Flex XLC modules are about twice as expensive.

I have two questions:

Does anyone know (or have a link to determine) what memory chips are being used in these memory modules?

What RAM would you recommend for maximum overclocking??

Perhaps I did not make it clear in my example so I will try to simplify it.

I ran PL7 with all the phase adjusts on auto Orthos stable @ 1140mhz performance level 7 using the 333/800 divider @ 475 x 8.

With the exact same settings all be it changing from the 333/800 divider to the 266/667 I was not able to run PL6 with the 913 BIOS so I ran PL7 & enabled 9 out of the 10 read delay phases to try & run closer to PL6.

With the later BIOS's I firstly found I could run all 10 of the phases on enabled & later after more playing I found I could run PL6 @ 1200MHz too.

Well I knew I was going to get slammed for it but I still stand bye what I said.

I know GTL tunning bring voltages across the board back within operating harmony & theoretically should be adjusted as you perhaps unbalance the board as you manually adjust voltages away from stock but how critical are they as they don't appear critical to me.

Who actually knows what the board is set at with GTL's disabled, do they automatically adjust behind the scenes or not. its all very well graphing the manual adjustments but what is the board doing disabled or auto ?

I can run 3.8GHz Orthos stable @ near DDR1200 without touching GTL's & having heard plenty of people telling me I must adjust GTL's for a less brute force more sophisticated & educated overclock that will result in lower voltages I as of yet I haven't seen one single piece of evidence from anyone demonstrating there rig running comparable to mine GTL tuned with less voltage.

Don't get me wrong I too have spent days GTL tuning but for me Mr average they make no appreciable difference on my rig in regards to real life 24/7 stability.

It may be the GTL's have sweet spots for running lower voltages @ certain fsb etc but I cant find them. If you can demonstrate GTL tuning on this board can save voltage I and I am sure everyone subscribed to this thread would like to see your findings.

At the end of the day I am just another chap with off the shelf retail parts running IMO a decent overclock which is comparable if not better than most of the others I see around & although there may be hand picked parts out there to beat mine but they are not accessible to the masses so in my opinion just don't count for comparison against Joe publics parts.

People appear to be getting the best luck with the Ballistix & OCZ personally given the money is no object approach I would snap the 9600 OCZ Flex kit up in 1/2 a heart beat.

Don't get me wrong the Crucials are fine sticks that will probably run shoulder to shoulder with the OCZ @ 1/2 the price but the OCZ's are rated to handle more warranted voltage. Its a tough call maybe you could get 2 sets of Ballistix one for bench pounding & one for best :D :shrug:

I thought it had been stated several times that yes they do dynamically change based on the VTT and NB voltages. The method used to derive Reference voltages leave no other option. As for as who else knows what their board sets I can't say. Can only speak for myself. I know precisely what the board sets when GTL is disabled.

If that is directed at me it couldn't be more off-base. I have never posted anything support related with other then retail. This particular board came straight from MotherboardPro. Grabbed off the shelve just like anyone else's board. The processors I use for posting in these type of threads are not only retail but most are bought used. And I try to keep most of my results to what I feel the majority of users will be able to obtain.

Just one quick question if I may. If you have found manual GTL settings to be of no benefit why are they manually set in the above post? It's just kinda confusing for users trying to make heads or tails out of all these settings.

Yes it had been mentioned several times & yes I knew they dynamically adjusted I think from an early GTL chart over @ TTR.

What I meant was do they must adjust them selfs away from there predetermined settings bye things like voltage fluctuation due to load, droop etc. I have no way of proving or disproving this accurately what does your scope show? I presume it must show a fluctuation in voltages due to load temperature etc & if so surely these factors are enough to effect your manual setting.

Ok you scoped yours & know exactly but you are one of few, mine could be the same then again it may not & as only one point out is enough to throw the rig out of whack I think its fair to say all boards are not going to perform the same. It would be nice if the BIOS showed you what had been automatically applied as a start reference point that you could work from.

No it wasn't aimed directly at you I apologise if thats the impression you got. What I was saying was basically anybody can beat anything with cherry picked components given the resources however there is a difference of opinion here between whether manual GTL tuning is necessary or not. I have on several occasions posted my specs showing that my rig works fine with GTL disabled & I ask anybody that challenges that to show/prove it. If you believe GTL tuning will show gains then show us so we can all benefit.

I haven't exactly found them no benefit but rather my rig runs equally as well disabled as it does manually adjusted which for me begs the questing why bother playing with them when disabled/behind the scenes auto does it all for you with apparently no margin of error.

The above specs have GTL disabled, yes you are right I have manually adjusted everything from 110 to 115 but these figures are greyed out & should not be in effect. I am also a creature of habit if it worked leave it alone.

CN :)

Here's a couple of screenshots for you. The first one is with GTL Reference voltages set to Disabled. The second one is with identical settings with the exception of GTL Reference voltages being set manually. The difference between me and maybe others is I'm not going to offer advice on speculation. Although my methods may not work for others I know they are based on what has been proven to work for me.

Hey guys... I hate to bother you but i have some questions on comparisons to the LT version.

I planned on purchasing the full X38 UT but I think the LT might be better for watercooling. Is there any performance difference between the 2?

Looks like I cannot get my X-Fi to work in the lowest PCI slot. Gonna have to hope that my ATI 550 pro will so I can swap them around...

On a happier note, am priming easily at 3.8Ghz/1050Mhz 5-5-511 on the 9/13/07 bios at 1.5v (which is more than I need, just ruling Vcore out) and it was effortless so far. A long road ahead of me, but I am optomistic based on the results I have had with the last 3 boards I have had.

Although my methods may not work for others I know they are based on what has been proven to work for me.

I appreciate you can show the difference GTL tuning made for you @ that clock but what I said earlier is bye simply switching "GTL+ Buffers Strength" from default strong to weak & leaving the "GTL Ref Voltage Control" disabled has the same effect.

GTL+ buffer strength strong = failure up around 3.6GHz without GTL manual adjustment where as GTL buffer strength to weak & leave GTL's disabled primes for ever so why mess about with GTL's ?

Anyway stability as you said yourself is not really under scrutiny here its whether GTL tuning will allow lower voltages to be used over GTL disabled/auto if you like.

Its 1:00am here so I am off to bed night night everyone.

At this point the two boards should be the same with the exception of onboard cooling. But you know how it is. Nothing is guaranteed until retail. Hopefully I'll have an LT version late next week and will know more.

testing two HIS radeon 3870's that arrived today. trying out crossfire on this board... must say first impressions are good. just put them in 40mins ago so I need some more time to play. First run of 3dmark06 pulled up 17290 at stock settings... doesn't seem like the 4x slot is hurting it as bad as i thought it would :)

so Crossfire isn't a problem with this board?

I would probably expect to get maybe 19-21k if i had an x38. Getting 18k right now with the cards at 860 core/2550 mem. I still want to play around with adjusting PCI-E frequency to see if it improves.

But yeah, other than the second 4x slot slowing it down a bit atm it worked without a hitch. PCI-e spacing was more than adequate (obviously). The only thing i had to do was change the PCIE Config option in bios from '1X 1X' to '4X NC' (effectively taking the 4 lanes from SB that are spread out by default across the board and giving them all to the middle PCI-E slot)

Edit: And crysis looks farkin amazing now :D
