Thanks for that, nifty. Have to try it now. ;)
Those wanting to buy Phenom 9750/9850 with this board -> here's the problems it has, I've wrote them here so you can decide: http://www.xtremesystems.org/forums/...5&postcount=13
I could not get 3100/3000/2700/2800 stable.
Still running 3000/2900/2700/2800 stable, stock volts.
Thats a nice summary KTE. I'm taking a break from the AX78 now , installing my Crosshair again now that there is a new bios I need to test :)
What about the Barcy? :(
BTW, 3000/3000/2700/2800 1.384v stable since my last post :D
It should be under way togehter with the L1N64WS/B unless I'm being ripped off. I sure hope not. BTW It is a BA stepping so I don't have too high hopes of overclocking it.
Oh ok.
Update is, ignore my last post results.
Latest stable is 3000/3000/2800/2800 1.35v ;)
Anything higher on volts will shutdown system within ~5-1200 minutes
Will you be able to auto clock that settings upon logging on? I tested some "apply upon log on" settings with AOD with little luck. You tested that?
I haven't tested it yet TBH but I use Sams MSR tool to change to the required VID and 2800 across all cores on boot, auto.Quote:

Here's my latest: http://www.xtremesystems.org/forums/...&postcount=792
1.352v suddenly switched off idling at 2900/2900/2700/2800 after mre than 30 hours. A PWM thing, cut power at once. :(
Cool, so you found the upper limit. Does it always shutdown or also freeze or fail prime?Quote:

Just shuts down suddenly :(
No load failing or idle failing - its a different problem. PSU cuts power to system at once usually under no load. I think SnM test L2 Cache can replicate it, I'm testing it now.
Tried stock MHz/stock volts, 26°C ambients, low fanspeeds, 221W AC
Attachment 78219
Next up is 1.328v just to see if it can hack it.
I've got little time, quickly adding what I can.
I tested and the limit for the MB PWM causing that shutoff is 1.328v - with 9850BE nothing at that or higher will be stable on this board, S&M will fail during L2 Cache testing.
LIKMARK please keep in mind what I just added.
For x2 owners 1.45v seems to be about max 24/7 for a QUIET setup. My PC is virtually silent. Thats with modded sinks and letting faneq do its thing mind you. YMMV
Current settings 3.22 @ 1.4v (might go lower v yet) Ram = 1076 cas 4 2.2v!! This board pushes ramz REALLY nicely. Back running beta bios, AOD didnt work with official bios 12 for me??. Have extra chip on hand, had to hot flash once already. :) Extra chip cost $13.80 after shipping US monies.
I was a little disappointed with the board pwm wise but in reality she is a stellar board overall if you can live with lower volts to your cpu. In a day and age of trying to live greener it is probably for the best.
Please forgive me for asking this question as I did real the entire thread twice but I saw a few conflicting answers. Does this board indeed post with the shipping BIOS when using a Phenom 9850BE and 2X2GB PC2-6400 ram? I believe you guys say it will, I just would love a verification. I rushed out and bought this damn ASUS board without thinking or logic when I got my Phenom and I need a good $100 board. Thanks in advance!
Todays AX78's are shipped with BIOS 12, 9850BE is not on the support list, but forum user KTE is using 9850BE with this board. I myself have been using ballistix with this board, although mem compatability is not one of this boards strong aspects. KTE is experiencing difficulties when feeding above a certain amount of voltage to the cpu as the PWMs closes down because of "out of spec" load. I think he can run it at about 1,4vcore before shut down.Quote:

EDIT: BTW, just sold my AX78, Phenom 9500 and Ballistix, so there is no more Phenom fun for me for a while. Opteron and L1N64WS/B is in customs right now :)
the general feeling is bios 12 will post with the 9850be fine, and it should run stock fine also. the board is much more picky with phenom/ram than x2/ram however, it apears to be a sotrming board forr am with x2's and meerly ok for phenom.
when it comes to overclocking 125w cpu's then your going to be limited in the volts you can manage - with the 6400+be about 1.475 to 1.5v is the limit. for the phenom about 1.35v to 1.4v
Thanks for the info guys! At this point, it could not be any worse than my current board which is pretty much guaranteed to explode if I try to overclock it. I have such a limited budge that my choice is limited to the 770 based boards and this one seems to be the strongest. Any other info if greatly appreciated!!!
There is at least one person @ the abit forums running a 9850BE + AX78 and it worked with the shipping BIOS. Like LINMARK said, KTE is running one as well. I have v.13beta02 (available here) running and have no problems. When you start overclocking, you're definitely going to want to cool that PWM off, they run quite warm once you put some Vcore to these Phenoms, especially that 125W one.
If it will post with the shipping bios then my life would be complete if for just a short time. I don't have another CPU to flash with and spending $115 (after shipping) is even slightly over what I can scrape up to buy it so it will be a brick if it cannot post with the shipping bios. Thanks again!
Over current mod,
not varified and theory only.
resistor marked 59c, to the very top of board, in the middle of a bank of 5. middle of the ISL6232 chip then head up puts you about correct.
The resistance should be about 40K (its a 40K2 resistor) try nudging this down a little and you should see the v-core drop and the max current drop also (eg now gets even worse) - if someone brave can confirm this with pencil mod then thats the simpleish fix - replace this resistor with trimpots letting you nudge this value up and down from here. pushing resistance UP should raise v-core and OCP limit. down reducing both.
At your own risk!
Not Varified!
Calculated from Pages taken from datasheet for the IC and from much digging about with a cheap multimeter and 5 year old A-level electronics. so dont hurt me if im wrong
hi guys,
i have a question or rather a request. can some please post pictures of what options are available when you enter the PCIEXP1 and PCIEXP2?
what i mean is is there an option to bring down the multiplier to 4x for both slots?
i would really appreciate some screen shots for both.
And has anyone used this mobo in crossfire mode?
link to image of what i mean

here is a screen shot of one of the slots, can someone please post a picture of the other slot please. i would really appreciate it.
Thanks

Hello,
just wanted to buy the board to overclock with an AMD 4850e
Is there anybody who got some experiences? Does it work, does the Board recognize the 4x50e models?
And does the GSkill F2-8000CL5D-4GBPQ Kit work with the board?
Would be nice if anybody has some thoughts on this.
Abit forums have a thread about compatibility for ram/hsf for this board, it is linked to earlier in this thread. I think the ram you mention work with the board. Check out abit homepage for cpu support. The board works without issues for all processors exept 125W cpus, where some users have had issues. That should not be a problem with your 45W cpu..
The linkage you referenced (plus a couple more to some crap I threw together):
- RAM / HSF Compatibility Info.
- How To Build Thread. (Geared toward newer builders; skip the text and look @ the pics.)
- Heatpipe Mod Thread.
(56k warning on the last two, lots of pics...does anyone at Xtreme Systems even have 56k? ;) )
so i just received the board now and everything works fine, especially the overclocking but there is one big problem:
The Network connection is so slow that every page just need hours to open and downloading is impossible, don't know whats going on...
I'm using Windows XP x64 and the latest Marvell Yukon Drivers from their website and i also tried it with the drivers from the packaged cd but there is no chance...
Rest of my HW:
Abit AX78 Bios 12
4GB Gskill - DDR1000
AMD 4850e @ 3,0Ghz (261x11,5)
X1950 Pro
X-Fi
Hitachi HDD
Antec Earth Watts 380
does anybody has an idea, because i need internet on my main pc,
this is soo strange :/
That is rather strange; haven't heard of that before. Just to be sure; it's operating, but not fast, right? Try uninstalling it from device manager and letting Windows auto-detect it. This is a fresh install of Windows, right? You might want to restart your router as well just for giggles.
yeah it works :)
i switched the ports of my two pcs at my network sockets on the wall and then it works but the other pc got the same issues so i made a direct connect to the router and now everything is fine.
Don't know why one of the sockets is broken, but this is very confusing. Because it worked before i changed the motherboard... :/
