Official DFI LanParty UT X38-T2R(and LT) Discussion/Review/Overclock/Guide Thread

I think im going to have to settle on 3.8ghz - i can seem to get it stable and useable on that. (by stable i mean a 30 min OCCT test while ill run for longer)

the weird thing is that @ 9.5x400 i've got slower memory & L1 Cache than the pic below but ive got higher L2 cache speed?



i'm just going to try to concentrate on tightening the timings and leave it at that

Right now I'm testing CPU @445x9=4005 and RAM @534/5-5-4-9 - all (sub)timings the same sa given few posts above

Everest memory performance looks like this

[zsamz_]

i took out my mushkins with d9gkx to test out a pair of kingston value d9ghm
2.2v
i finally broke 11000 lol
with a little tweakin should get better

[zsamz_]

my new 24/7
cpu 1.54v
vdmm 2.1v

[Origin_Unknown]

woot nice one zsamz_

[zanzabar]

zamz nice work, is that your normal 4 gmh sticks but with performance lvl 7 and whats the NB voltage and phase settings still eaeee eaaee

[Panthols]

I was looking in the DFI manual and it said that PCIE 1, 3 and 4 are all x16. I'm wondering if there would be an impact on performance if I run my single GPU in slot 4? In case anyone is wondering why, my OCZ xtc ram cooler won't fit with the GPU in slot 1 and my SB waterblock blocks slot 3.

[zanzabar]

slot 4 is a 4x electrical pci-e1 slot so i wouldent use it for grafix, but slot 3 works great

and u dont need a water block on the SB it barely needs a heat sink

zamz nice work, is that your normal 4 gmh sticks but with performance lvl 7 and whats the NB voltage and phase settings still eaeee eaaee

no bud its my crappy kingston value pc2-667 lol "d9gmh"
i had to go performance level 8 @ 535fsb lol but phase settings are eaeee
i got another pair in my hr-07s
my 2 sets of ballistix 8500 been put away for a rainy day
i put my mushkins that couldnt go past 1155 with 2.32v into my old p35 now they doin 1200+ with 2.22v
i wasnt happy with those d9gkx but my son lovin em now

since i broke 11000mbs my next goal is to break 12000mbs

takin a break soon i will see how high i can go lol gonna try 2.32v next

[zanzabar]

now i really cant wait for my block to arrive so i can flash to the x48 bios on a new block and keep my original intact

[Origin_Unknown]

since i broke 11000mbs my next goal is to break 12000mbs

mine is still something like 7800mbs

[Effet]

dfi board not too crazy for d9gkx
when you get yours you will find out
i can do 1250mhz with d9gmh 2.2v
but with d9gkx had a hard time @1150mhz 2.32v
but you can do 1080mhz 4-4-4-12 2.3v
i personnaly dont like goin over 2.26v on d9s

Hmm..ok. I got mine yesterday and I set the Vdimm to 2,35v, which is the intended volt at 1150MHz, and I ran them at 1280MHz fine. Will try higher clocks and I'll post screens later on.

man i thought you had it already biosdepot is quick n cheap
took 5 days for me to get mine i'm in canada
i paid 24$ for 2 chips shipped
i miss the days when it way 5$ for a damn chip

mine is still something like 7800mbs

my sons pc was @ 8500mbs now he happy with 10200

i just tested mine in p35c-ds3r n they did 1226 with 2.22v
i couldnt do 1055+ with 2.32v in the x38

[quake6]

If you flash it to x48,can you flash it to x38 again?

[Effet]

Anyone tried to flash a x38 to x48 with the 03/20 bios? Results?

[t_ski]

Yes, zsamz did:

It's still working. X48 is just a binned X38.

Ah sweet, might flash aswell.

Btw http://img90.imageshack.us/img90/3228/mem1254rk2.jpg

Was able to boot up at 1300MHz, but as soon as windows started to load, BSOD ruined the fun =/
2,38v is at the edge of doable for me, 2,4 > is quite risky.

I'm not that familiar with the GTL settings. How's the impact of increasing/decreasing them? When is it effective to increase/decrease them?

dont worry i gonna try it verry soon and will report back

edit:ok i loaded it i see nothing different in performance over first bios
btw i used winflash was lazy lol

edit2:i dont like the new bios system reboots n posting code errors

Which hr-07 did you pick up? I'm trying to decide between the older one and the dual. I like the old setup because of the fan mounting and the extra surface area.

the ones i got were the highrise
you gotta get the lower ones to run 4 stix

[PhilDoc]

So you got the H ones? I'll only be running 2 sticks. Trying to decide between the H/L series or the original.

whatever you do get the ones that come in a kit of 2 the singles cost more
i like em high they get more air "no i not smokin"

you gotta get 2 low n 2 high to run 4 stix not 4 high lol

so did i, and proof that itÄs the same thing is

a) the flash works
b) the bios says x38/x48 series on the logon screen, so they dont even differ between x38/x48

Performance increase with X48 bios i'd say is wishful thinking....or as eva2000 said probably because NB voltage-table glitch is still in the bios, resulting in dangerously high NB voltages for all "made in china" boards selecting certain NB voltages, resulting in better stability at tighter timings (yeah, running NB at 1.76V, much luck with that

I personally dont think the X48 bios is worth it:
a) old bugs are sitll in there (still resetting to default cmos values with 8x multi and certain straps on otherwise stable settings)
b) dangerous NB voltages bug might kill china boards
c) no real performance increase (IMHO)

[PhilDoc]

Yeah, I know. Can you put a fan on the H/L series. I know the singles cost more, but you can mount a fan easily and it has more surface area to cool. I haven't seen any reviews to see witch is better and the cost is only about $4 higher. I'm only planing on running 2 sticks anyway. Maybe I'll just flip a coin, lol.
