Help me get a X2 3800+ to 2800Mhz please !!

Shocky-FM · 18 Mar 2006 at 22:06

Using same rig in sig but for different CPU,

Its currently at 2785Mhz ! but just isnt stable at 2800Mhz..

Its at max volts for this mobo, 1.5V ! 280X10 (333) 3xHTT..Latest bios... Any advise getting a it stable at 2.8? Something maybe I havent tried? 52C load before failing prime95 after about 35min

Hacked Bios with 1.5v+ volts maybe?? (Wishful thinking)

The A8N can only supply 1.5v? I find that suprising as my Epox goes to something silly like 1.7v.

Probably a bios update or a vmod, obviously try the bios first

Its quite annoying, a slight voltage increase would probably do it... I'm on the latest bios atm soo.. dunno .. :confused:

I so should have got a DFI but to late now.

im sure you can add a bit more to the 1.5 volts. isnt there a special VID thing on them?

Don't think so, only other settings HTT and Chipset voltage.,

Yep

Usually you can only select up to 1.5 or 1.55V with the CPU Voltage option but there's something like VID which allows you to overvolt slightly

Having said that though, I've just been reading the manual for the board and under "CPU Voltage" in "JumperFree Configuration" you can set it up to 1.65V

Yeah In the manual it shows upto 1.65 but I only have the option upto 1.5V. :confused:

welshtom · 19 Mar 2006 at 09:55

it sounds like 1.5 + 10%? is there no option for the modifyer?

if not, flash the bios to a better one

Hi,

The ASUS A8N-SLI Premium goes up to 1.55vCore, although it says 1.65vCore in the manual I think this is CPU dependant. With an Opteron 170 plugged in the BIOS shows me up to 1.55vCore (same as my 146 mono-core allowed).

I think the X2 is restricting the voltage allowable. . .

Just found this, hope it helps.

There is a control similar to the vid special on the DFIs which should let you have up to 1.95v.
Just noticed youve got the Asus premium board so it might not help!

EDIT/ FORGET THE ABOVE I TYPED had a heavy night.
I found a thread in the EOC forum and one guy says he is using bios 1004 which offers 1.65v on the CPU.

juno_first · 19 Mar 2006 at 13:43

Cant push >1.5v thru my A8Nsli-p either

wish I could as it just ain't stable at 2.8 even if temp is 15c idle

Damn, 1.850 !, my mobo sucks so badly !!

.. Memory wont even overclock 20mhz on this board either... just keep giving me errors behond 270MHz regardless of timings and voltage...

So stuck at 230 2.5.3.3.6.. Joy !

does your mobo not over volt?

i have the same mobo and setting vcore to 1.425 in bios puts out 1.47-1.49.

i want to get 2.8ghz too but theres no way im setting it to 1.5v the way this thing over volts lol

Mine doesnt overvolt unfortunately...

Why are you so desperate to get higher frequency, you've already pushed both cores 750Mhz higher, thats over a 3rd faster than stock....I'd be more than happy with a dual core processor at 2.75! It must be lightening fast!

I just hate being held back when I know it can do more..

Tell you what, I'll swap you with my Opty 170 that can only do 2.6 at 1.55V !

At 2.7, the machine doesn't even boot the bios, so a 3800 X2 @ 2.75... Well...

Yes but I want 2.8 damit !

This 3800+ doesnt overclock much more then my old 4400+ which is disapointing to me..

might help if you crack the ihs off. Maybe, but also maybe not.
