| Administrator | DFI Lanparty LT X38-T2R Info, overclocking tips & photos [56k user friendly] Short url: http://i4memory.com/dfix38/ Christmas post this is - thought I'd share something special with you folks this time round. I've decided to compile this thread differently from my previous motherboard threads, in that I will try to make it as 56k user friendly as possible - pretty hard for me as you know, I love my screenshots ![]() Thanks to DFI Taiwan, I've been playing with this DFI Lanparty LT X38-T2R for the past 11 days. Still using the initial out of the box bios release which is 11/28 bios. [Click thumbnail for larger version, use keyboard arrow keys to cycle through images] View more images here. Used Artic Cooling MX-2 thermal paste on northbridge and replaced SB and PWM heatsinks' thermal paste with MX-2 as well. Installing WinXP Pro SP2 right now ![]() Downloads:
Latest Official bios:
Latest beta bios:
Some folks asked why cpu heatsink can't be oriented the other way with fan exhausting from back of case. Best I can do to explain, is take a photo of HR-05 side on with stock DFI X38 heatsink to compare. As far as I can tell the stock DFI LT X38 NB heatsink's wider base is what blocks the Thermalright Ultra 120 Extreme's heatpipes from being oriented the way where fan exhausts air out of case. (click thumbnail for larger version) ![]() Not 100% sure but hope that helps some folks. |

System specs
Vcore seems to overvolt - but i have loadline calibration enabled. So will see how it does disabled. Vcore = 1.3125v bios set = 1.344v With Samsung 750GB 32MB HD753LJ SATA disk on DFI LP LT X38-T2R as OS drive. Installed multi-boot windows on several partitions. This is what HDTACH and HDTune looked like on OS drive Not bad I must say for a populated drive |

DFI LP LT X38-T2R has an awesome memory related bios option to adjust read delay phases - basically away of tweaking tRD / performance levels between the set tRD / performance level and the level below it. This can squeeze out a bit more performance in your memory and may help high FSB/memory clocking situations as well. Read delay phase adjusts - all AUTO Update: Seems the best way to tweak this is to work with enabling read delay phase adjustments only on Channel 1, leaving Channel 2's read delay phase adjustments on AUTO. I found the last 3 Phase pull-in settings on each channel don't do much at all for memory performance or latencies when enabled. Only the first 2 phase pull-ins can alter performance. Maybe because my subtimings are already tight ?? Read delay phases - last 3 Phase pull-in settings enabled - 1st and 2nd Phase pull-in settings AUTO |

| Administrator | Re: DFI Lanparty LT X38-T2R - Info, overclocking tips & photos [56k user friendly] Update: From 12/28 bios onwards, the Clock fine delay values changed from numeric values 1-14 IIRC, to xxxPS values. Nothing has changed in the process of finding the optimal Clock fine delay values as outlined at DFI LP UT P35-T2R / DFI LP LT X38-T2R - working with 'CLK Fine Delay' just the values you select has changed. Another memory related option in DFI LP LT X38-T2R bios, is Clock Fine Delay - tuning this can have a dramatic effect on boosting your memory overclocking headroom as well as reducing memory voltage needed. A sticky thread can be found here for some tips on finding optimal clock fine delay values. You will see some examples below of this ![]() Clock Fine Delay At Work Still very early into my testing of how memory behave on DFI LP LT X38-T2R with 11/28 bios. It basically seems like a more matured version of what is implemented on DFI LP UT P35-T2R ![]() Playing with 2:3 divider (266/800) and 2x 1GB Crucial Ballistix PC2-8500, I found myself hitting memory clock wall at several points while doing my routine Memtest86+ v1.70 testing. Only salvation to break through that memory clock wall was fine tuning Clock Fine Delay values for DIMM 1 & 3. To my surprise I broke through that 651Mhz wall and ended up at 666Mhz 5-5-5-9 at 2.49v being single Super Pi 32M stable!
So here's where I end up at so far 666Mhz 5-5-5-9 at 2.49v! Pretty awesome for initially having hit a brick wall at 651Mhz 5-5-5-9!

| Administrator | Re: DFI Lanparty LT X38-T2R - Info, overclocking tips & photos [56k user friendly] Clock Fine Delay At Work Continued.... Swapped out one set of 2x 1GB Crucial Ballistix PC2-8500 for another set of 2x 1GB Crucial Ballistix PC2-8500 since I'm re-testing all my memory on DFI LP LT X38-T2R to find the best matched pair for this board ![]() Seems similar process to gain stability occurs with this set too - meaning fine tuning clock fine delay DIMM 1 + 3 as well as controller clock fine delay allows this memory to fly as high if not slightly better than the first set I tested.

Swapped in a 3rd kit, this time in dimm slot 2+4 with 2x1GB Cruciall Ballistix PC2-8500 Tracer modules. At first had troubles even with 600Mhz 5-5-5-9 PL6 at 2.19v with memtest86+ v1.70 test #5 having a few errors on 1st pass. Fine tune clock fine delay values and I'm memtesting without problems at 640Mhz 5-5-5-9 PL6 at same 2.19v vdimm ! 645Mhz 5-5-5-9 PL6 took only 2.23v bios set for single Super Pi 32M!!!! This particular set of Ballistix Tracers took 2.4-2.45v to do 651mhz 5-5-5-15 on Asus P5K Deluxe!.
