DFI NF4 Ultra/SLi-D BUGS and Fixes Thread

[Wingz]

A thing to test for all who are using any kind of high-voltage loving memory (BH-5, BH-6, maybe also CH-5, Twinmos UTT, OCZ VX et al) - well, except maybe for the very big guys (OPP, OPB), as for them it's running fine anyway

I'd like to know how your memory behaves in memtest test #5 IF using 3.5 Vdimm or more (which, of course, is derived from the 5v rail).

What I have observed with my BH-5 kit and OCZ VX as well, as soon as I up the Vdimm to 3.5v or more in bios, and loop memtest test #5 for a few loops (10 is enough, you can see it then), memory starts showing memtest errors EXACTLY AT THE SAME MEMORY ADDRESS all the time. Usually if memory is not memtest stable, it usually throws out errors at various addresses (maybe in the same range but almost never in the same address, as one chip on the memory is failing, and it is usually the size of 64 Mb now). Moreover, this happens also (my VX is memtest stable up to 262 htt 1:1) on lower speeds, say, 255 htt. The only variable here which seems to impact these errors, is the Vdimm. As soon as I lower it, the errors disappear.

Thanks.

i have the same issue but with my Msi NF3 board anything over 3.4v i get errors at the same place on every pass and even lowering to 240HTT will still get the errors.

i think that i find new issue in my sli-dr
when first boot set to floopy the post jest stuck when the boot is starting to run, and the os dont boot.
when the the floopy is disabled the os start fine.

Hmm, could those perhaps be memtest errors itself? Anybody else experiencing this?

No problem here, boot order is as follows: floppy, cd-rom, hdd. Are you sure you have set it everything right? These boards have the most tricky boot order sequence algorithm I've ever seen.

No more problem with ram .. It appears it doesnt like the yellow dimms

after 2 formats this is still happening

anyone???

im sure , the boot order was :
first - removable - floopy
second - cd rom
third - hd

its jest stuck, but when the first (floopy) set to disabled - work fine

For those that are interested i think i figured it out... the screen gets horribly distorted and shakes like a mofo when the refresh rate is at 75hz.. even though my monitor can handle that... hopefully this is something that nvidia will fix in their next drivers as 60hz runs fine

I've got a problem with 2*512 OCZ VX...

an hour ago they works fine @ 268 (memtest stable)
now they work until 262...

Why???

I'm waiting for OPP screen...

strange, when i run my mushkins bh5 @ 3.4-3.5v i had same problems @ 260-265, always errors on same adress, even when lowering the voltage, checked the ram at friend of me, and looks like its not broken. i will re-check when i get it back today, i ll have a look on which adress it fails.

also have massive usb problems, machine sometimes hangs on bios boot screen with usb plugged in and very often windows doesent recognize usb devices. yesterday changed usb cable and all went fine (usb hhd read speed was 30mb/sec . today turned machine on and no usb devices, even after rebooting / on-off swichting. just gone. i have a look at this after work

I'm gonna jump on the DFI bandwagon after I'll clear some details.

- Which SATA ports are locked in the SLI-DR model? (There are 8 ports, 4xSil and 4xNF4)
- Revisions R.A02 etc. indicates the BIOS date only (not anything that is hardware related) right? If so you can flash to a newer BIOS afterwards.

Thanks!

yo, my SLI-DR setup is now running, but there are a few quirks...

When I initially put everything together and installed XP, everything worked great, no issues. However, as soon as I powered down and tried to power back up, I had no video signal, and I thought maybe it is hanging before the bios screen (I had no video, so I couldn't really tell).

So I tried everything, plugging in 4 pin molex, removing RAM, replacing RAM, etc, and then in one of the tries, I thought I'd just leave it, and then video miraculously came back when XP finishes loading. Now, I have seen the bios startup screen about 3 times, other than those times, I have no video when its POSTING - but as soon as XP finishes loading, video comes on... does anyone have any idea what the issue may be :/

Im thinking its a DFI bios issue - I tried flashing the XFX 6800GT with a newer bios, and still no go. I wanna tweak this beast, but I can't see the bios! :P Thanks in advance!

try lowering the vdimm -.1

using 3.3v via psu rail or 5v jumper ? maybe psu rail fluctuations causing it ?

[eva2000]

I have 2x512 tccd running at 2.87v at 300HTT 1-1 2.5-3-3-7-1T on a beta SLI version. Also bios 0201. I can't figure out why Blue's tccd aren't getting along there.

maybe board/bios is only part of the issue, maybe it's interaction with cpu ondie memory controller as well ? you using FX-55

I'm using the +5v rail.
The psu is a OCZ PS 520W.
It is very stable...

I tried to lower the voltage, but i 've the same errors...

this morning i was able to do 268@ 3.6...

Can someone come out with a procedure and correct BIOS options for using this board with TCCD, since most of us are having this problem... Thanks!

This is also my biggest issue right now.

We need someone from DFI to chime in about now. Any reps in this forum?

What reps ?? Does DFI have reps that come to this forum? Or any forum?

The Guys at DFI-Street are forum moderators only, from what I see.

1. To everyone that owns a DFI Motherboard: I am a full time DFI employee, hired to do support for them in this forum. I am here for all of you, and will work hard to solve any problems that you bring to our attention.

ALSO NOTE: RGone is a fellow DFI Employee here to assist you (and me!)

This means you aren't just getting answers from someone that might or might not know the answer to your question/problem. It means that whatever I cannot answer myself, and no one else has the answer, I will forward your problem/question on to the engineers at DFI themselves.

DFI is, in my opinion, the best motherboard maker I have ever been involved with, and not just because of the products they make. They have the best support efforts in the industry, and work to make sure each customer is happy, which in turn virtually guarantees that we will all be more than willing to try new DFI products as they come out. You will all see the truth of this statement as time goes on!

Hey Lidocaine, why don't you pass around some of yourself to help numb the pain?

hey xgman ...........I had my "dose" this weekend. PSU failed but OCZ is working real hard to rectify this............props to Tony and crew! Fortunately for me, this board is doing great!..............*knocks on wood*

This board is super sweet, just gotta work some "bugs" out. Could it be anything less with Oskar driving the bus? I'd like to see Oskar pay a visit here to help some folks out too.
