Bad Axe 2 at 500 FSB!

[danny_discus]

Time for a drink! Got the Bad Axe 2 board up to 500 FSB :woot: 1MB SuperPi Stable off of water and air cooling. These boards rock, best 975X available! The BIOS is to the MAX!

System:

Intel Bad Axe 2 with Danger Den Chipset waterblock for Bad Axe board and fan over southbridge
X6800 Core 2 Duo with Danger Den TDX waterblock
1 GB Corsair XMS2-8500

Volts:
vMCH - 2.38v
vCore - 1.45v
vFSB - 1.5
vDimm - 2.2v

To be able to hit these voltages on the MCH I had to put a fan over the southbridge before that I was only able to hit 2.1v on the MCH. Waiting on a waterblock to modify for the southbridge. :)

Cheers! :toast:

Wonderful FSB indeed. :cheers: 500MHz on i975x on above-ambient cooling is a very rare sight.

[Blknoel]

Crazy volts on NB explains the FSB I suppose.

Nice work indeed, would be cool if you could pull some more intensive benches on it.

I will try when I get a waterblock setup for the Southbridge.

[Omastar]

Holy crap. Nice work. :)

[Boble76]

vMCH - 2.38v
:rocker: - Uuh..sick!

Nice.

[Radamanthys]

2.38v vmch you are insane....

Nice clocks

[trans am]

Really good job danny

[^don.k's^]

Congrats, but thats A LOT of voltage, ive seen P5W64's which wont need so much VMCH for that, also my p5w dh needs 2,15vmch on air, not 1:1 tho...

[T07N]

wouldn't your nb burn on in couple months due to those voltages?

[danny_discus]

I would suppose so, choosing my time wisely at 500FSB :)

[afireinside]

500 fsb on 975 with 1066 strap is BLAZING FAST! Some very high vmch to. Think you could run with cold water and try to get 500 3d stable? 500 1:1 would do some damage in 01 and am3.

[rick_fx]

Wow, 2.38V Vmch is plain crazy :D

[^don.k's^]

Yes, i know someone who burned the chipset of his p5w dh with ~2,35v after one OC session. :stick: I hope you dont love too much that mobo :p:

[danny_discus]

Well although I do love the motherboard, it wouldn't be worthy of Xtreme if I worried how long it will last. :D

Well, there's a thin line between being "xtreme" and purely ignorant and stupid. You don't burn down hardware because you are rich to replace them every week to prove you are "xtreme", if this is the case, screw that "xtreme" title.

If we consider OCing an art needing much research, attention and patience, so do it exquisitely, using brute force without intellect is silly.

That was not directed at you danny =), more like of what I feel OCers should keep in mind when OCing their hardware.

And a wise one should be worried about how long it will last, because if it turns out to be a hard-to-find good clocker, depending on you luck, it may take you a while to get a hand on a similar or better one if this one goes bad. Also love the environment and your wallet.

Summing it up, "extreme" is different from "brutal" ;)
Example: 2.38v on air is "brutal" and damaging, but 2.38v with DI or good water is "wise" =D

[danny_discus]

LOL, no insult taken as this is not on air and only used when I am lookin for the max. :) 24/7 is 9x400 at 1.55 volts to NB. Also that is why I haven't tried anymore voltage because I am waiting for a waterblock for the SB as keeping this cool has proved to increase and stabilze high FSB. So maybe more than 1M SuperPi stability is obtainable at lower voltage. By all means I am not rich so longevity is a factor.

[rob[GL]]

Good work! You have convinced me to stick with my BADAXE!

[Jaan]

Me too hitting 500MHz BIOS wall- 500 is max in bios and still no clocken for this mobo yet ...Frank? :rolleyes:
Bad Axe 2, E6300, 2x512MB cheap A-data6400, room aircooled, cpu@inbox, NB@default sink+ 80mm vent.
Vcore 1,4V , Vmch 2,1V, Vfsb 1,5V, Vddr 2,3V, 1333 strap, FSB:MEM 1:1

validation: http://valid.x86-secret.com/show_oc?id=157802
Funny thing is how sharply max FSB responds to Vmch- at 2,1V it fully stable@500MHz, dropping Vmch to 2V and mobo is even not capable to load windows :eek:
At 1066 starp and same voltage I have 495MHz stable, so only 5MHz difference.
I'm monitored Vmch voltage (Fluke 123)- there is no such thing as Vmch drop- under load Vmch is even rise a little(+0,002V) :)
Here is a my older post- 490MHz 3D stable
http://www.xtremesystems.org/forums/showthread.php?p=1939141#post1939141
So if Intel make new BIOS where we can change multi down on usual (not xtreme) cpu and move max FSB to...550-600MHz this mobo will be very nice board for OC imho.

[Athens[2004]]

Wtf !!!!!!!!! badaxe2 is on killing spree!!!!!!!! :slapass: :slapass:

[krampak]

Did you mod the Vmch ? (how?) Mine only goes up to 1.7V :stick: I'm stuck at 450Mhz FSB 1.7Vmch.

[icon57]

bad axe 2 looks better and better to me everyday ;)

[danny_discus]

Yeah I modded the vMCH. Its the same as the Bad Axe 1.

[[cTx]Philosophy]

Nice 500 :)

I need something capable of 500 plus, I was looking @ P5B DLX, but this is a sweet fsb for 975..

This would be nice for a Q6600 :) me thinks

[mcstarr25]

that board really is nice

and the price drop is even nicer


..decisions decisions.

[Punisher!]

Wonderful FSB! Which is the mean?

Well. I must say i do not agree :)
If anyone has the means to pursue the records with whatever means it takes, feel free to push on. After all it is just at stupid to take an ln2 container to one's board. It will never stay dry. And hey, water is also known for killing HW. I read that Onepagebook had killed 17 XBX's at a time. I call xtreme.
Being afraid of killing stuff just doesn't go well with being xtreme imo. And it is awful close to brutality, if not equal to.
But i will agree that if you're running on air a good waterloop might be a better investment than a new mobo or two ;)

Some update of my attemt to OC i975 to 100% (533MHz):)
hardware and settings:

500MHz S-pi 32M stable, 1:1 (http://www.oc.pri.ee/BadAxe/BX2/i975@500MHz_32M.png) (and 3D/prime too)
525MHz 1:1 s-pi 1M (http://www.oc.pri.ee/BadAxe/BX2/i975@525_1-1_s-pi.png)
this 525MHz is max for mem, next screen using 4:3 FSB:mem divider:

now some OT result too :P
using same cold air cooling and inbox cooler I switched cpu to lapped E6700:

Very nice, but how does it do on the 1066 strap?

thats I call overclocker, when u mod your house to have better results :D, for the WR I think ~560 is fsb WR for 975X but on vapor phase change & ~2.4V.

:toast:

[nikolas61]

Nice work

:clap:

[uclajd]

Ludicrous! :toast:

To think not too long ago, you couldn't even OC Intel boards by design.

[Jaan]

thank you :toast:

Very nice, but how does it do on the 1066 strap?
515 was 1M stable, 520 not.
Vmch was up to 2,35V. (530, 533MHz)
LN2 pots for chipset is ready, lets hope I'm not be the first artificer, who practicly finds "Vmch sure killing voltage" :D
btw, I'm interested to see this 560MHz on i975 on screen.
And can anyone tell me max safe voltage for it?
uclajd, yes it realy nice to see Intel board, that actualy really good in serious OC.
I see only one bad thing for now- I can't change multy down, only xtreeme cpu's allow that.
But this is easy to fix with bios..lets hope :)

I've used Kentsfield (beta?) inbox cooler- its bigger and with more powerful fan: http://www.oc.pri.ee/Kent/QX6700_inbox.jpg

I remember Stilt was once write here in XS, that DDR1200 is extremly hard on i975..hmm, I have DDR600 1M stable on old Bad Axe,
too bad I don't have any proof of that on screen :( this screen) (http://www.oc.pri.ee/Conroe/ddr1200.PNG)

[Gautam]

Great. :) 515 is awesome.

The old Bad Axe had a broken 4:5 divider on the 1333 strap. In reality it was just running 1:1. Plenty of people hit some ridiculous speeds, even 600Mhz CAS 3 thanks to this glitch. CPU-Z still reported 4:5 of course, but the speeds reported were false.

Hey wanted to congratulate you on an awesome job on the Bad Axe 2 OC's! :woot:

Now onto the "killing voltage" on the Bad Axe 2. I believe the board limits you to around 2.4 something and it will reboot, etc like when you turn vCore up past 1.75v but without the annoying siren alert. This has happened to me when first trying to get 500 FSB on mine. :mad:
