OPB's DFI NF4 SLI-DR Basic Tests

hi all, I know some of you laready ordered DFI
So, I did some test on my daily basis setting on this board.
Hope it helps.
Let's see some impotant settings under bios.
These parameters are what I have been discussing with Oskar so far.
from Advance chipset:
" Errata 94 Enhancement"..if you are using winne, you gotta disable this!

some OC:

for me, 292fsb can only use 2.6v vdimm

some Dram parameters
Bank interleave..is here.

thanks all:D

nice LCD

...droooooool

OPB, so what's that "Errata 64 Enhancement" option for then?

nice any windows app to see if bank interleaving is in fact enabled ?

can you do a bank interleave on/off comparison benchmark of memory bandwidth ?

I will definitely do that later on :toast:

OPB. Good results with those setup. Your SMARTGUADIAN is showing ATX 12V as 11.9V. I beleive you are using PC Power & Cooling PSU which is adjustable. Try and adjust it to something like 12.5 +/- 0.2V. for a stable 12V rail. The 3.3 and 5V rail seems okay.

smartguardian has never been accurate normal under reports by 0.2-0.3v probably same for DFI NF4

Always good to have your preview, OPB. :toast:

Looks like in your testing the board favors FSB over tight timings - which GSkill sticks are you using for the DDR600 benches? Was planning on getting OCZ VX for my SLI-DR, but now I'm not so sure ;)

EDIT: I see you're using the TCCD LE's, my bad.

Hey... you mean at High memory FSB... you can't run more than 2.6v? Or you mean at high HTT, you can't run more than 2.6v?

That sucks.. I was planning to run my CPU at 305x9, and use a memory divider on some UTT or OCZ VX at 166Mhz divider... but I would need vdimm to be high at those HTT frequencies.

I wouldn't buy VX if you can get TCCD and want to get high fsb. Simple as that

It's easier to get low timing with VX than getting high FSB with the TCCD running slightly higher timing at 1:1 that is why VX are nice as well too :)

good work guy, OPB... :) Which BIOS use 4 LDT Vol setting ? Thx

:D THX - nice work dude. Cross Ya fingers for me - need 11 x 306 or 10 x 336.

What about " Errata 94 Enhancement" when usin' FX-55 and no winnie ???

On or Off ???

:toast:

:confused: Any answer ???

:toast:

OPB, just a question, is this your work bench computer, or your home pc?

Errata 94 Enhancement? what is that? :toast:

DevilR, that's my personal use computer.:D


**************************************

Zanr Zij,

I think either 1.25 or 2.01:D

*****************

quicksilverXP, sorry to let you confused,
I mean I don't have to use high vdimm to do that high fsb..:D

i think u need to get a good air cooler tbh, 200C a bit high :rolleyes:

the windows hardware shows it wrong, think it is something like 228-250=-22 or something like thata you need to do to get the right temps in windows

Nice results.

Good for you to show us the bios options. Seems to have a load of options on mem...

That LCD of yours rocks :D Im thinking of buying a new LCD. Is it a widescreen btw ? Sorry for off topic ;)

:D Me also don't know - but now I know it has to be off (#17 )........ :toast:

I'm pretty sure it's Apple's Widescreen LCDs.... either the 20 inch of the 23 inch... or if my eyes are deceiving me.. the 30 inch. That alone makes all of us hate you.

You got it right quick...

and then he arrives with these results which are just 'basic' tests :rolleyes:

j/k :D :banana:

OPB does it again...

So what would you guys reccomend for my DFI SLI-DR: G.SKILL LE's or some VX??? :confused:

i'd say either one will be good... looks like opb got some insane stuff with his gskill at low volts... and the board has the high voltage for the VX...

so if you want 2-2-2-5, get the VX, if you wanna show off 300mhz... get the gskill. ;)

:D Yep - but do not foerget the "good old" BH-5, always good to have some reserved.
On my NEO2 they are maxed out at 275MHz 2-2-2-5 with 3,9 Vcore, but who knows, maybe we will see a better performance on DFI NF4 - even with 4,0 Vdimm.
I'm 99% sure we will - tested 2 kits BH-5 (CORSAIR & MUSHKIN) and both maxed out at exactly the same point: 275 - so I think it's the NEO2 and not the BH-5 which is holding me back.

For higher HTT I use the G.Skill 4800LA. :toast:

I've got a very noobish question here... Intel person attempting AMD platform for the 1st time and trying to absorb as much as possible in the last weeks... please bear with me...

OPB, I see above that you have the following settings:
292 HTT X 4x LDT = 1168Mhz HTT Data Rate
300 HTT X 4x LDT = 1200Mhz HTT Data Rate
230 HTT X 5x LDT = 1150Mhz HTT Data Rate

I was under the impression that HTT x LDT cannot exceed 1000Mhz HTT Data Rate as instability would arise. I've checked DFI's site (you've guessed what m/b I'll be attempting :D ) and I can see the NF4 supports up to 2000MT/s or 1000Mhz HTT Data Rate (am I right in concluding this?)...

My question would be how you managed to run your settings as above when you've clearly exceeded the max HTT of the NF4 platform?
What is the max HTT of the NF4 platform?

I appreciate the input and clarification from all :)

Officially, 1000.

Unofficially, whatever you can push it to ;)

Some boards work under higher HTT settings than others, and the DFI would certainly be at the top of the list :banana:

yeah some boards handle >1000 better, i.e. DFI NF4 i think Oskar said 1200-1250 should be fine

This is Errata 94:
"94 Sequential Prefetch Feature May Cause Incorrect Processor
Operation
Description
On an instruction cache miss, the sequential prefetch mechanism may enable the early prefetch of the
next sequential cache line. Under a highly specific set of internal pipeline conditions this mechanism
may cause the processor to hang or execute incorrect code in 64-bit systems running 32-bit
compatibility mode applications.
Potential Effect on System
Processor may deadlock or execute incorrect code.
Suggested Workaround
BIOS should disable IC sequential prefetch by setting IC_CFG.DIS_SEQ_PREFETCH (bit 11 of
MSR C001_1021).
Fix Planned
Yes"

In short, it applies to all 3F,C0 and CG Revisions (Winchesters are D0 revision and should be fine).
It also only is an issue if you run a 64 bit OS with some 32bit applications in compatibility mode.

So you can safely keep it disabled if you don't run a 64-bit OS, otherwise you might want to leave it on for 3F,C0 and CG (e.g. Clawhammer and Newcastle).

Thanks for the heads up matt and eva :)

:D THX - now we all know. :toast:

Are those GSkill TCCD LE 2x512 better than OCZ Plat PC3200 Rev 2? Or similar?

Similar, both have TCCD and a Brainpower PCB.

Nice, i've heard that I could put my plat rev2 to ddr600 with 3.3V, or maybe it's too much voltage for this tccd? :p:

What kinda voltage does TCCD like on these boards? I know normally for 280-300mhz TCCD takes about 2.7-2.8vdimm. But i've been seeing that it takes 2.9-3.1vdimm for same speeds on DFI nf4? BTW I have 2x256 of Gskill LE.

:D Try it....... :toast:

Nope, higher vdimm didn't help, should I be maxing out at 280mhz?

OPB,
Please could you ask Oskar why it takes more voltage on the DFI NF4 with TCCD's than on Neo2 or Neo4 ????

opb whats max. with your fx-55?

heh?you sure? HTT I think by that 1000 he asked for HT not HTT :p

anyway the default iis 1000(200x5) on nF4 800(200x4) on nF3 but both they can go over 1000 1200/1300 nF4 10xx/11xx on nF3 :D

nice thread OPB!!

one Q : how u managed to get high Sandra's Bandwidth efficiency on 512x2 ? you het like .. 91% if im not mistaken

I don't think so..same ram I need to use 2.85 to do 290, but under DFI SLI-DR..I got this: do msn, everything..super pi 8m, 2.67v
what'd you think?:D

http://www.e04hardware.com/ocx/opb/2928m.jpg

I think you got handpicked sticks. :)

Hummm??? my LE's wont even post in the SLI-DR on 2.65v

anyone tried with ocz pc4200EL .....the hynix, that wasnt great on engineer samples...wanna find out if i should purchase more rams...perhaps some Gskill

how about USB trouble? most of my things are connected via usb...and most of them by usb 2.0

weeeeeeeeeeeeeeeeeeee at last i got my modd and equip in place and gets it up and running..at least in the bios...

my problem (and i have read a lot on dfi street and opb and so ons guides...but i cant get the board to run stable at any speeds with 2 sticks of dynamite (RAM)
3200+ winny, dfi sli-dr, ocz pc4200el hynix..a lot of air and no oc so far....only thing i can try tomorrow ould be to them into yellow sockets.

bump, screenshots seem to be down, could anyone help me im having huge problems with my lp nf4 ultra

I'm not sure what you want a screenshot of but WindWithMe has also done a review so perhaps something in there might help...
