Ok... is important to verify the single condition of two modules...
then you must test separately two modules ...
Plug in it in the first module only and in the first slot and set your ram to 275mhz and 2.5-3-3-6 (2.8v and all other parameters). Verify if it does the same problem.
After, you test the second module (always in the first channel) with same values in the bios.

i tested one a8r32mvp in single channel with one module, it's no good.
(i tested with the 2 modules separately )
with 280fsb, which have to be the various voltages? (HT,core voltage,pci express)

When i set in vcore one 1.45V but vcore overvoltage one disabled,which is the real vcore cpu?

I think it's not super like motherboard.
problem with my gskill, low vcore and vcore not stable :-(

With the higher clock (above 280mhz) in cpu frequency the HT voltage must to be to 1.5v
With the higher clock (above 120-130mhz) in PCI-E frequency the voltage must to be to 1.5v
With high frequency and air cooled systems the CPU voltage (overvoltage included) must to be under 1.5v...
Above this value many users (of this forum) with DFI motherboard and without liquid cooled have damaged their CPUs.

The real value is 1.47-1.49v. Asus overvolted tje cpu by deafault (I have the same problem with my A8N-VM CSM... It works, by default, at 1.40v with my 3800x2 and not at 1.35v).

This motherboard is very stable with TCCD chips (on 4800DSU2-1GBFF modules) up to 320mhz (DDR640) at 3-6-6-13 (configuration tested by nyphs: a user of this thread).
About low voltage core if you have an liquid cooled system I don't advise this motherboard. Attention, with high voltage you can risk to damage your processor.
About vcore not stable, i can tell to you this: if you choose a voltage in the bios it will not be never lower to selected value.

devo fare un pò d'ordine...
scusa... ne ho appena cancellato uno...

Salve

oggi ho ordinato la mobo pero mi é venuto un dubbio. Sara sufficiente la mia attuale BeQuiet P5 520 per il mio nuo Pc?

AMD 4600+ dual core
A8r32
Nvidia 6800
3 Hitachi sataII da 250 GB
2 dvdrw + 1 cdrw
creative audigy 2 zs
Avermedia tv pci
8 ventilatori
Zalmann fanbuss per regolare i ventilatori

Credo di si pero.... opinioni

grazie

Hai cambiato solo la main? Prima cosa avevi?

Ho cambiato il processore -prima avevo un venice 3000- la memoria -primza 2x512- ed ho aggiunto un nuovo hard disk.

thank you for your reply nvidia men, but i have got also one dfi nf4 ultra d, and my ram gskill gbff i have got this result:
2.5 3 3 6 @ 300
2.5 4 4 8 @315 easily maybe i can +++

and the asus can't start with 2.5 3 3 7 @275

Then this situation is very strange...
Many DFI bios modify the CMD-ADDR to 2T during the post...
Verify if your nf4 ultra d is really at 1T when you access to Windows with Athlon64 Tweaker.

i have news. I scucceeded to start (on A8R32MVP) at 270 to 2.5-3-3-7, i didn't check stability, but witch 275 fsb the bios crashed, impossible to start

[dyn@]

for the TCCD @280 2.5-4-4-8 fsb to got the maxi performance, it's better skew value faster or 0 or skew value faster and 255?

The best value is that with greater stability increasing by step of 1mhz the frequency (above 280mhz)...
In order to know it, you must test all values...

[dyn@]

but into the bios there are an option "skew value".Which is the best setting for skew value for tccd ram?

[Samoht]

So we start to speak english too... wowo! hwupgrade international

Well well, "skew" value is actually used (best if leaved on "auto") by the mainboard to configure (read "fine tuning") the "compatibility" between different banks of ram. As you may know, even two identical banks (DIMMs) of ram are not totally similar - there might be some phisical differences also during the manifacturing. "Skew" tries then to retard or anticipate a little bit the signal of one (or more) bank(s) to make it work the best way possible with other memory banks, in order to prevent read/write errors.

I suggest you to leave that value on "auto".

[Samoht]

Alla fine ho risolto il problema della ram: erano di fatto i banchi di memoria ad avere qualcosa di strano. Ho provato a mettere 4 banchi da 256Mb identici di TwinMos pc3200 e vanno tutti fino a 210Mhz (420ddr). Poi ho messo 2 banchi di Kingmax HardCore da 512mb (pc4000) e vanno in dual channel fino a 510Mhz. Ma con un paio di Adata Vitesta ddr500 non c'è verso: se ne metto uno, il pc parte. Se ne metto 2 ma non in dual channel, ok, ma se li metto in dual channel, non c'è verso.

I have exposed this before...
For TCCD chips the best skew value (at 300mhz) are:
- Delay 150ps (or normal) for the first channel (A);
- Advance 300ps for the second channel (B).
With other frequencies a manual test is necessary (see the guide).

Hello Samoht. The skew problem does not depend by physical differences between the memory modules, but by different access of the CPU to memory between the first and the second channel to the various frequencies.

azzo io ho appena ordinato il secondo banco di vitesta ddr500 x fare il dual channel....ma t succede cn i banchi da 512mb?

ragazzi prima che sclero help
ho preso un enermax liberty 620W

la spia verde si accende ma non parte una sega, domani mi sa che lo provo su un altro pc. per caso avete notizie di incompatibilita?

Hai "attackmentato" il connettore da 12V direttamente alla presa di alimentazione supplementare vicino alla CPU? Attento al verso con cui lo metti dato che i connettori degli Enermax hanno 4 poli e ne vanno collegati solo due (quelli in cui è serigrafato, in bianco da me, il valore di 12v appunto).
Ciao.

non ho capito sinceramente io ho agganciato il 24 poli, 20+4 e il 4 poli con tutti e 4 i pin attaccati, se puoi postami una foto
