Any difference between DFI nF4 board's?

[Dani]

I mean difference in HTT overclocking.
My new Ultra-D R.AB0 cant handle +325HTT, LDT/HTT voltage dont help

4000+ SD can do 2944MHz SP8M, my KHX3500 DW50 2225 1T DC 1:1 271FSB SP8M thruogh but not +325HTT*4-9
Tested lots of BIOSes, no go.
Temps are ok.

My old Ultra-D R.A02 did +370HTT

I read from an other thread that NEW Ultra-D is worst, SLI-D good and SLI-DR best, I'm talking about NEW boards with R.ABO revision and HTT OC

Sorry my horrible english

Here is the photo of that revision, its somewhere between PCI slots

I'm I wrong or is it thru

[ZeroX]

I dont know anything about the revisions, but the most of de DFI nf4 i have seen do +370HTT easy... My dfi nf3 did 410HTT... I think u have bad luck..

I would agree with Zerox, sounds like you got a dud somehow.

[largon]

Oma Ultra-D menee myös vain sen 320, eikä ole bioksesta kiinni.

ZeroX,
nF3 is a totally different animal.

Ei ole BIOSista kiinni, vanhat hyvät 3.10p, 5.10-2 ei tahdo kunnolla toimia tässä R.AB0 lankussa
[/finnish]
Yeah, nF3 is'nt nF4

Photo added with revision (+370HTT revision )

Now I'm Priming with my new DFI nF4 SLI-DR with R.AA0 330HTT (just for test) with similar setup (CPU, mems in orange, BIOS, SATA 4 everything, weird

SO it's fixed Dani? How about your R.B0?

Thanks

[Dani]

I sold my R.AB0 to my friend who dont OC
Now Im pleased with this R.AA0, have'nt try much but at least 350HTT Prime95 stable for hours.
R.AB0 did'nt pass SP1M +320HTT@any settings

[sauria]

Thanks Dani, is this a late revision issue on others R.BO or was yours a dud?

[Dani]

I have read on other forums about this same issue, new boards with R.B0 are'nt the same that old R.AA0, R.A02 and R.A03

[sauria]

Thanks, we'll see how mine does. Do you have any links to those issues threads?

[Dani]

Cant remember, it was 2-3weeks ago...
One thread was here in XS, someone posted in DFI Forums exc.

[The Stilt]

Err...
Don´t you think that there "might" be some variations between the different nForce4 batches? Some batches are good, some of them aren´t. The way it has always been.

I assume that nVidia chooses the best chips to be labeled as nForce4 SLI and the second grade chips as nForce4 Ultra or 4x, etc.

[sauria]

Is that the only diference in the board revision?

[Daved+]

When you said R.B0, you meant R.AB0?

[Dani]

Yes, I mean R.AB0

[sauria]

When you said R.B0, you meant R.AB0?

Do you like your R.AB0 Daved+?

[Daved+]

Do you like your R.AB0 Daved+?

I can't get it stable at 294HTT... yeah, I love it sooo much

I don't know what the f* I'm going to do, I sold my MSI Neo4 because it only did 313HTT and now I got a DFI NF4 that does 293!!!

[sauria]

I sold a MSI Diamond that did 312MHz -- we'll see what my SLI-DR R.AB0 can do

Let us know ASAP... Or I'll be selling my R. AB0

[sauria]

ok will do, CPU, PSU, XP-90C and TCCD should be installed tomorrow.

[sauria]

I do have the SLI-DR, not Ultra-D. Perhaps that will do better?

Who knows?! Try yourself! I can't wait to know how good your mobo is.
