**Official DFI LanParty UT X48-T2R(and LT) Discussion

[merlin76]

you need the new bios which should be up soon, Oskar tuned the board to help overclocking PSC IC's like the ones we use on the 1066 reapers you quoted there.

I will try to post guides for these and the 1150 flex2 over at the ocz forum to help those looking for settings...BUT remember, im not interested in CPU overclocking so those who moan that they can not hit the CPU clocks with the ram where they want it will be asked to test with CPU's (quads especially) at near stock speeds due to the nature of the chipset.

I got my Flex II yesterday and so far they are working great with LT X38 and current BIOS (03/14). I'm very happy with it.

DDR2-1168 was the max stable clock I could achieve:


Although the screen shows tRD 8 it's 7, only one phase is running at 8.
My CPU does not like FSB higher than 460, so I'm a bit limited on dividers.

This could get my new 24/7 setting:


// Edit

I have been able to reduce tRD to 6, so performance improved a bit.



FSB266 and 266/1066 divider or FSB333 and 333/1066 divider did not cause any issues to me. DDR2-1200 was no go with current BIOS, I could get it nearly stable at DDR2-1192. Do you have any news on the new BIOS files with PSC IC optimizations?

[davidk21770]

I'm seeing lots of numbers here, but has anyone formed any opinions yet on whether this board is better than the competition (say Gigabyte or Asus)? Or whether it's a good choice for a fast reliable overclock?

Thanks.

hmm i say it was way better than the maximus formula and rampage that i had.. for ddr2.. .

[Slam]

Any word on next bios release, or is there a good site for beta releases?

Thanks

[ZenEffect]

i could say the exact opposite, but only when referring to "fast" overclock. dfi motherboards definitely take time to set up to run... but once set up THEY ARE FAST AS HELL

[zfactor]

just joined the group.... cant wait to get it.. now i have a basically brand new x38 dfi going up for sale lol just couldnt resist trying this out..

[Martinm210]

I think I'll be buying this board as soon as I save up the $$. Goodbye EVGA 680i, hello DFI..

I might even take the time to fabricate some custom blocks for this one...

[zsamz_]

you guys should be lookin hard @ the dfi ut p35 cause its way better lol
only thing i see better on x38-48 is runing 4 sticks n crossfire
unless they come with a nice bios to give same performance as the dfi p35 lol
i went back to the x38 just to keep my p35 nice n fresh lol

I don't see any difference in performance setting these options to "Fast". Most important seems setting "T2 Dispatch" to "Enabled" whenever possible. When it comes to 24/7 stability I noticed that setting these options to "Normal" improved stability a lot, at least with my old G.Skill HZ, and it did not cost performance. With BIOS versions prior than 1/11 I saw some improvements but now I don't.

only bandwidth increase
just turbo not stable for me

After tRD, those two settings have the biggest influence on performance then any other setting.

[Praz]

Don't know what the problem is there. There should be several hundred MB/s difference in Read and a difference in Latency depending on how the Enhanced settings are configured.

[merlin76]

With BIOS versions prior 1/11 I saw differences in bandwith and latency, with 1/11 and 3/14 it does not seem to matter anymore. I don't know, either.

[Praz]

The only board I have set up at the moment is the UT x48. I'll check what it does. Might be able to point DFI to these posts and find out what's going on.

[merlin76]

That's nice, thanks.

[Martinm210]

I went ahead and made my order for this board a few minutes ago..

This review was convincing enough for me..

after spending a week figuring out this mobo, and tweaking it out. ive come to 2 conclusion. #1 latency on dfi is approx 2ns slower than my asus, and read bandwidth is about 100/mb less however ive been able to run @ the same speed before w/ lower overall volts and my read + write are about 200mb faster. perhaps i have more tweaking to do but im at a kind of a stand still atm. dont know where else i can get a bit more performance from other than more fsb or cpu freq.

i wil post up my full settings w/ bandwidth screen shots @ around 3pst. thanks in advance for any suggestions.

I've noticed this as well. I have nothing left to tweak as far as memory goes and I'm a little slower on the bandwidth and latency. I experienced the same thing with the DFI 680i when comparing it to my P5K-D and EVGA 680i. I can also confirm that this board runs at much lower volts than my Formula Rampage conversion but wasn't that the point of the x48 chipset, the higher binned north bridge?

I think my memory's holding me back at the moment. I couldn't run my 4x1GB Mushkin's on this board so now I am using 2x2GB OCZ Flex II's. For some reason I am having issues running the 400 strap @ 400MHz w/o losening my timmings too much.

[Jokah]

Hi, I just bought the UT mobo and I have some problem to run my ram at stock speed its a Gskill F2-8500CL5D-4GBPK, anyone who use this ram please can share the exact settings?

[ZenEffect]

memset is still reading my tRTP values as 2 higher than set in bios. is this a known issue w/ the software?

quick s/c @ 1200



once again, slower than my asus... but still nothing to sneeze at.

*edit*
also, i can not just set +1.4v in bios as it crashes and i have to reset cmos, however i can set +1.4v in bios if i use the special vid section. is this something w/ the board i should be worried about?

*edit edit*

ok NOW we are getting somewhere. latency is still not as low as on the asus HOWEVER ive exceeded read, write, and copy bandwidth.



apparently i left the pull ins on auto instead of enabling them to get pl7
also tweaked tREF from stock 3120T to 14592T in memset. that netted me 200 more mb read and almost 2ns less latency. now to stability test it. i expect it to pass w/ flying colors as ive done so before w/ same settings. just re-checking at this point.. 2 hours orthos ram test and im calling it a day. this dfi is getting better and better every day

[TouGe]

Great job clocking your RAM Zen. Really impressed.

I've got tRTP set to 3 in BIOS but MemSet 3.5 sees it as 5 as well. All other values are reported correctly.

cost me $45 after rebate

*edit*
had to set trfc to 50 to stabilize it. apparently 46 is too tight
