Re: DFI Lanparty LT X38-T2R - Info, overclocking tips & photos [56k user friendly]

2x1GB Crucial Ballistix PC2-8500 Tracer @601Mhz 4-4-4-9 at 2.55v

DFI LP LT X38-T2R is the first motherboard ever for me to allow me to pass Super Pi 32M at 600mhz 4-4-4-x settings below <2.60v memory voltage. After fine tuning clock and command fine delay I managed to pull off 32M @601.9Mhz 4-4-4-9 at 2.55v straight boot from bios. Then using Memset tightened tRFC and tRAS and tWR to 25, 8 and 11 (bios or 10 memset) respectively and still pass a Super Pi 32M run.

Unfortunately, it seems the Super Pi 32M time on DFI LP LT X38-T2R even at 9x401FSB 601.9Mhz 4-4-4-9 was around 2-4 seconds slower than on DFI LP UT P35-T2R @9x400FSB 600Mhz 5-4-4-5 at basically same timings/subtimings and bios tweaks.

@601.9Mhz 4-4-4-9 at 2.55v

Tightened subtimings in Memset (same windows session)

It seems to come down to bandwidth and latency differences between DFI LP LT X38-T2R vs LP UT P35-T2R.

X38-T2R


P35-T2R

Yes, tRFC and tWR is a bit tighter at 24 and 10 instead of 30 and 14 but that didn't make up for super pi or everest bandwidth differences much.

Re: DFI Lanparty LT X38-T2R - Info, overclocking tips & photos [56k user friendly]

2x1GB Crucial Ballistix PC2-8500 Tracer @675Mhz 5-5-5-9 at 2.55v


Swapped the dimm slots for this pair of Crucial Ballistix PC2-8500 Tracers from dimm slot 2+4 (yellow slots) to 1+3 (green slots) and seems can overclock a bit better. I can now hit 675Mhz 5-5-5-9 at 2.55v - highest ever CAS5 memory clock for this pair of Crucial Ballistix PC2-8500 Tracers at Super Pi 32M passable speeds!

Still 32M time seems around 4-10 seconds slower at 3600Mhz mark than 965P/P35 chipset. I guess the loosened internal latencies on X38 allow memory to clock higher but at a cost of clock for clock performance ? Still I am looking forward to 3dmark benchmarks with X38 x16+x16 PCI-E slots

Managed to shave 4 seconds off 32M time and drop memory latency a tad

Re: DFI Lanparty LT X38-T2R - Info, overclocking tips & photos [56k user friendly]

E6850 L720A489
@4005Mhz at 1.472v
@4107Mhz at 1.584v

Some quick 1hr Prime95 stability sessions just to find out how my E6850 L720A489 does on DFI LP LT X38-T2R.
  • 4005Mhz at 1.472v (1.3875v + 104.1% bios set) = Prime95 ~1hr
  • 4107Mhz at 1.584v (1.4875v + 103.77%) = Prime95 ~1hr (accidently overwrote the prime95 loaded screenshot when saving the post load idle one )

Re: DFI Lanparty LT X38-T2R - Info, overclocking tips & photos [56k user friendly]

12/28 Beta Bios - 5:8 divider tests

Previously on 11/28 bios, certain memory dividers had stability issues. 4:5 divider couldn't do more than 440FSB, 3:5 divider had issues of stability even at 333FSB due to tight performance level of 4 and 5:8 divider wouldn't even allow system to boot regardless of cpu FSB set.

Now 12/28 beta bios http://www.dfi.com.tw/Support/Downlo...FLAG=B&SITE=US has at least moved one step closer, with fixing the 5:8 divider.

From 11/28 bios 5:8 no system boot, to 12/28 beta bios doing 400FSB 5:8 640Mhz 5-5-5-15 on memory! Having some difficulties tuning clock fine delay for above 400FSB on 5:8 so far since using 2x1GB Crucial Ballistix PC2-8500 Tracers on 2:3 divider manages upto 681mhz 5-5-5-x more easily!

5:8 divider needs slightly more vdimm than 2:3 divider but still pretty good for 640mhz 5-5-5-15 at 2.35v bios set.

DFI LT X38-T2R Other Tests


Spent a bit more time with DFI LT X38-T2R since last with other specific tests. Thought I'd link to these tests here as well.

DFI LT X38-T2R R.A03 GTL Ref voltage measurements


Decided to get off my butt and do some multimeter measurements for GTL Ref CPU & NB voltages as well for my DFI LT X38-T2R as it's pretty tricky with QX9650 quad core cpus and trying to break 450FSB without tweaking GTL Ref CPU & NB voltages. Measurements read from Clunks' photos read points from DFI provided info.

So far these are the measurements I've done for my DFI LT X38-T2R R.A03 revision board with 3/14 official bios and Made in Taiwan PCB. Of interest is seeing what the default GTL Ref volts are when the GTL Ref options are disabled - they default to approximately, 63%, 63% and 67% respectively.
