Asus Crosshair IV 0801 Bios

I will use my invisable powers to fight crime.....

Not only with CPUz Brian, but I've had 2 of my best 3DMark scores not successfully upload because of the FSB/HT fluctuation. When it checks your system between tests, if there is any change of parameters whatsoever it will invalidate your score and it won't submit, I'm sure you've probably had that happen over the years with other boards and setups.

Best regards,

Bleh no need to upload anymore randi. I rarely upload anything. Only need FM link for top 20 spots.

cpu-z cpu-zmem, gpuz and GT details all thats needed for a submission or a review or forums

Well, that's exactly what's happening...



I had it set to 1.200000 and it set itself to 1.052 on the first boot. Meanwhile i did what *chew described (save profile/load defaults/reload profile), hope somehow it fixes it.

Boot the rig, go into the bios and then shutdown the PSU... wait a few secs, turn it up again --> should be an OC failed, press f1 and then :

Try to work with the Offset value instead of manual... and see if pops up again...

Good luck

Hmm, I just assemble my rig, after ln2 session what was yesterday. Board start with full reset bios, and new cpu installed (955BE what was inside yesterday,lol). I set everything, and check swing. Swing is gone.

I set 200 ht speed, cpu-z show 200.7-200.8 -whatever I doing - what was "normal" with 0707 bios. Now, works well with 0801 too. Dunno what happened..

High swing might be under high frequencies only... I set eg only 208 in bios, Turbo V or ROG connect reads out 210... on air I have almost no swing either...

Think we better get data together what swing at what ht clock, total cpu speed, HT link,...cooling used.

Think I'm gonna give the CH IV one last spin on wednesday to see what happens with the Thuban... will prolly have to return the board to Asus on friday...

Yesterday, HT swing was me on air too for both cpu. (955BE, 1090T BE).

It seems, 0801 bios gave more stability for my 955BE.

4Ghz Prime, real ~ 1,421v (before ~1,435)

I did the Bios clear using the button on the back of the board after swapping chips. I also had to do this after major OCing changes. If I clear bois and then make my changes, I have no HT Ref Swing. I am using currently 305HT Ref 4.1ghz 1.53v

Same thing, this BIOS is poop

I was just messing with the offset voltage a while back, saving, booting again to check the values and came up with 1.23v for the NB/CPU.

Happy, booted into Windows to do some testing when i got a BSOD and went "WTF?". I booted into the BIOS again, checked voltages and NB/CPU was at a dangerous 1.38v

I give up, i'll just wait for another BIOS, this was happening with my Maximus 3 GENE and i returned her to get this... useless pile of electronics... Meh @ ASUS, you're starting to disappoint me MAJOR.

[Leeghoofd]

So your board overvolts ? I'm getting lost now ....

I adjusted the OFFSET of the CPU/NB and kept booting with the new settings into the BIOS to check when the voltage was set to 1.23v (the one i wanted). When i was finally reading 1.23v on the CPU/NB, booted again into windows until that BSOD. When i went into the BIOS again and checked voltages, it was reading 1.38v...

What matters here is that the motherboard changes CPU/NB voltage to its content and it appears to be completely random WHEN it does it

[charged3800z24]

well one thing I can say, is for the first time I have been able to get more out of my OCZ 1600BE Cas8 modules then on any other board. Though the timings are not the best, but this ram has never been able to do this on other boards. I'll try a 32M run to see how it is..

GPU's can go much higher but I was focused on CPU passage.

Just noticed the 0801 bios has been removed from the Asus website,i wonder why.????

[NaMcO]

I hope they're working on some sort of fix, the motherboard is simply awesome WHEN it works. It's so annoying not knowing when it's stable or not

Yes this is an awsome board,but like you say,the bios really needs sorting out,all sorts of glitches,overvolting,change something in the bios and it wont boot,etc etc,begining to get on my nerves.

Not very hard to not know. Use RC tweak it or a dmm......when CPU_NB volt drops it's not stable.....

I guess that's the final option until ASUS does something about it. Connect a DMM to the measurement point and keep resetting until the voltage readout is ok

[CrimInalA]

I also use 0801 and i don't seem to have any problems regarding cpu-nb voltage drops .
The only thing i see is the swaying core (bus) speed, and the fact that it overvolts a lot .
Is this only with certain hardware combinations maybe ?
It does hang often on a failed overclock , requiring me to shut off my PSU before trying to boot .


Also CORE implementation is poor as of now .

restarting doesn't fix this usually. Like i said before save your profile. Load setup defaults boot then reload profile, problem solved.

TBH although annoying this is ocing. Nothing is guranteed. Users running at stock should not experience this.

The only overvolting i see under load with LLC enabled. I haven't had any issues regarding CPU-NB voltage, i'm using the manual settings, not the offset.

Still waiting for a new bios though, this one seem to have some quirks.

it is still on the ftp site

[NCspecV81]

I have to physically power down the PSU before the CPU-NB volts are similar to the settings in the bios. A restart just makes it go way lower and stay lower.

[FlanK3r]

to time remain at 0707...some bugs, but great OC for me.

[thijs]

hmm, if you check out the asus FTP, last 'change' is yesterday, the 18th. for bios 0801, perhaps they changed something?

[Leeghoofd]

Exact bios at first glance...

I would call that a workaround Brian, not a problem fix...
