1405 bios is open for discussion and linkage

[Tony]

Guys I have word its now ok to link the bios if you have it, Anandtech will have a review up that explains what the bios does and shows some gains in overclocking.

If Asus is reading this thread, please in future bios get rid of that power-down thing during overclocking and restarting. We would like our other hardwares to survive too.

The board is reseting the pll (changing strap).
That is a feature, not a fault.

my experience so far:
with 1305 bios, at 1.95v pcie crapped out, with all 14xx bioses, the limit is 1.89v.
no fsb gain whatsoever. though i flashed using afudos, but i didn't reset cmos.
there's no chipset subtimings yet and looking at memset, all timings were the same, with 1305 and 1405.
+there's a new "digital home" option now. dunno exactly what it does

[BulldogPO]

Yeh, I wondered that Digital Home feature also.
Seems to be very stable bios.
We want adjustable subtimings!

Links?

as I heard, this happens due to the chipset limitations, unable to restore clocks, it only happens if system is oced, what would be possible benification of this, i have no idea, but I am quite sure that disks don't love it

Any idea when the Anand article will come online? It's last thing on a friday afternoon (in the UK at least) and i don't want to have to wait until monday for it (although of course, i have no choice in the matter).

If i go ahead and flash it now, am i likely to run into any trouble? e.g. my board not booting up, or the world exploding?

[don_vercetti]

Ok, have flashed to 1405. Just a few things; no new memory timings, everything seems very much the same as with 1402, but i haven't tried clockin' yet.

the Digital Home feature claims to control fans, vcore, etc presumably as a replacement for C1E to keep the PC cool. I may try it out later, right now, i want to see (a) if my memory will run above 370mhz FSB with manual timings and (b) what is the max fsb i can hit.

Later.

EDIT;

370mhz fsb with manual timings still doesn't work with the RAM below.

Am now checking for any speed difference between 1402 and 1405 at 400mhz (2.8ghz) and then, will set off on the hunt for highest FSB.

[Tony]

I know some of what was changed but in respect of anandtech i will let them tell you. I hear the review will go up tomorrow.

[sombrio]

Bios 14.05 sucks. I need more vcore to put the same mhz with 9x multi. Back to bios 13.05

People often forget that bios updates are not necessarily designed to improve your overclock. In many cases, they just add support for newer CPU's or fix existing problems.

Your post should be made a sticky. It's getting really annoying to hear people asking about the temporary shutdown feature over and over again.

[Jimi...]

So is this bios final cause it's not on the Asus support site.

good to know its even more than i thought
i liked it because i thought it was simply doing it just to ensure a cold boot.

i have had overclocking problems with other boards because a reset wasnt a full cold boot and thus it made for uncertainty

[don_vercetti]

There is some serious performance deficiencies, that begin between 400mhz and 420mhz fsb. It MIGHT be because i can only run my memory at the lowest freq (640mhz @ 430fsb, so far) but i would hazard that the 1666fsb strap has been made selectable at this high FSB. Which is how it is letting us run much higher FSB.

I've only tested Pi1m so far though, so not entirely conclusive. But i'm getting 20.000s at 430x7, 640mhz where i get <19s with 420x7, 840mhz. Shall test further.

hmm.. did you cleared cmos after flashing?
i did not and i'm not seeing different strap. at least at 437mhz

[Jimi...]

So is this bios a beta then or what?

[WeaponII]

I think it's a beta...

[OBR]

When will be 1405 BIOS official on Asus web? BIOS linked above is beta ... and is THE SAME as 1403 .... no change in max FSB frequency, no change to better OC ..., dont bother to flash it.

UPDATE - I am back with 1305, this beta 1405 causes my 2x Raptor 150 in RAID0 unreadable in POST (because aftef clear CMOS are HDDs in BIOS in Enhanced IDE option). I have to disconnect my HDDs, go into BIOS, set HDDs as RAID, connect HDDs and then is everything OK, but i dont want to do this every clear CMOS ... this 1405 BIOS is c*ap.

[Jimi...]

Well I'm actually more interested in being able to lower the multiplier so I get a bit more out of my RAM.

[politenessman]

i can boot at slightly higher speeds with manual timings. but otherwise samo samo.

Ok but that feature should be one we can disable...

Something odd is going on here. I'm not sure if this is an issue with 1405, but I just setup a 8 X 400 config in the BIOS and I'm getting strange results in windows.

CPU-Z and Everest Ultimate are showing the multiplier as 8, with a resultant CPU frequency of 3.2GHz. However, Orthos, CoreTemp and Windows are displaying my CPU frequency as 3.6GHz, as if the multiplier were still at 9.





Is this normal?
