I find 3:5 to be more stable as well.

Anybody got a link to 0903? Pm me if you dont mind///
Its available on the ASUS site now.
http://dlsvr03.asus.com/pub/ASUS/mb/...ula/MF0903.zip
I am not experiencing this stablilty problem depending on slots.
With 4gb 4 X1gb I can do DDR 1150 + With two sticks in either colour slots I can easily do DDR 1200 +. These are afew hours Orthos memory and quad 32 mb pi stable.
DAMN!!!!!
How do i get my old bios back 0903 is horrible and I get a message stating that " I cant flash to my previous bios because they are older...or something like that."
Whatever you do please steer clear of 0903!!!
0903 is working well here. To flash back use a flash drive and do it in EZ flash
Sdumper which bios did you have previously and why do you think 0903 is so bad? Just out of interest.
here's my voltages on NB and ram. I used vista x64 in this run. I'm using the white ram slots. this bios I'm using is 0903. I'm doing 3.6Ghz 12x301 mem ratio 3:5 with mem speed at 501mhz
@Warboy, which part of MI you at? East Lansing here.
hey I'm trying to run OCCT and I do get to run it but how do i see the results ?
I ran both 0802 and 0901 at 5175 ghz and benched at 5.088 proof attached
I finally got it working but the damn thing is very picky. Still when I use the bios EZ Flash I cant flash back to 0901.
All of that said the 266 Strap is finally working and I was finally able to get is stable at 4.8ghz at 1.63vCore :( used to take 1.62...go figure.
So maybe i need to flash from a floppy boot...
I hooked up my waterchiller to the chipset to see if it helped my clocks over a normal watercooled chipset. Controlled the temperature so it was 29c with 1.85v (9c over ambient) and yes, it helped get an extra 5FSB higher stable. Hitting the chips max FSB of 470 isn't so dificult now either.

$1000.00? You guys are looking at the QX "Extreme units. Why not look into the mainstream Q9450 for sarting price of $316.00 or Q9300 for $266.00. The Q9300 looks to be replacing the Q6700, where as the E8400 is close to the E6850 in specs.
I'm waiting on the Q8450 @ 2.66GHz/2x6m L2/1333FSB on 45nm scheduled price so far of $316.00 San Jose, CA.
I want to be able to do 11x400 those chips can't do that
lol sorry I added some hard drives to my order so it's all filled up. ;)
proof would be the motherboard tab in that cpu-z screenshot ;)
Well, I just tried 0903 and it is quite simply atrocious.
It is causing ntfs.sys errors, where-as previously everything was fine with 0901.
Is it forcing a higher PCI-E frequency or something? I've locked it to 100, but I remember reading that ntfs.sys errors are usually associated with the PCI-E frequencies being pushed too hard.
Hmm.. odd, the voltages seemed fine according to hardware monitor, so I'm not sure why 0903 is so unstable for me :(
maybe your settings under 0901 weren't fully stable. I'm using my settings from the 0901 bios in 0903 and I'm not having any trouble. My pci-e is at 100 as well. I hope your not using prime to judge stability because I did that and my system was completely unstable.
When I try to flash my bios it doesn't recognize my usb flash drive . I hit Alt=F2 but its not there :( Whats the deal?
Hmm... ok the system is now stable, but only if I set SPD to Auto... I guess the new BIOS must be doing something completely different with the RAM.
I used to have 4-4-4-9-3-25-3(10)-3 and 7-3-5-4-5-4-5 working fine on 0901.
Reason for (10) is because Transaction Booster set to 0 changes tWR to 10 if it is set to 3 in the BIOS.
Everest seems to report Read Delay Phase Adjust as Neutral now, I don't think it was like that with the 0901 BIOS.
Guess I'll have to re-tweak the latencies bit by bit with this new BIOS, should be fun I guess *dies*
RE: "I want to be able to do 11x400 those chips can't do that"
why only aim for 400FSB. This is like stock for these X38's today. If talking bout the "QX", they were never really the better overclockers in the past, so I don't see why now, especially at a high multi like 11x. Why not try 6x or 7x for better FSB? The E8190 @ 2.66 is likely to be a god canidate for 500x8 on air for only $163.00. Why not see if the E8400 can go beyond 540FSB?
The entry level quad, Q9300, is gonna' have a 7.5x multi for 3.50GHz at 1333FSB. It will be interesting to see how the 0.5x works for overclocking
forget my previous question . Updated to 0903 :) woot woot !!! I'm thinking of going with water , this air stuff ain't cutting it .
Actually, just been playing around and 0903 is tons more fluid for some reason. There was definitely something not working with the previous BIOS' which we assumed did, and then they fixed it with 0903... probably to do with DRAM Static Read Control and the Transaction Booster causing big adjustments to the latencies.
So are a lot of people jumping to 0903? Im still on 505 I think...or something like that.
W00T!!!!!!!!!! I'm excited guys. BIOS 0902 is a golden one for me. I can FINALLY boot over 415 :D
Now testing at 415x9
DRAM Static Read Control and Transaction booster are both perforamnce options and if used wrong in an OC, of corse you will get instability. If you have good RAM and can get high FSB, you dont need to use mobo performance boosters. Do it yourself in manual timings if need be. Static Read Control helps keep the DRAM frequency to NB strap at a smooth curv as FSB scales upwards, so of corse if we disable it on top of adding booster, we limit FSB overclock and invoke a risk of instability.
This mobo has done 515FSB since BIOS v0401 and every one since with my E6750. Even though in v0602, I could manually use strap and DRAM frequency, I gained nothing from setting it to 333 and DDR1000 for the same 1:1, so I just leave it to "AUTO" from now on unless I need or want to test an updevider to see if worth the gain.
All right I can't actually boot over 400 FSB if I use DDR2-1066 5-5-5-15 so I'm running DDR2-800 4-4-4-12. Doesn't bother me one bit because I am not a big superpi runner or anything.....the only bench I run (other than SANDRA stuff for testing) is 3dmark06.
I'm currently running 425*9 and I'm going to test that for stability.
Whew.....after 3.6 the VCore scales freaking exponentially......I can boot at the same VCore but I crash instantly in Prime95. I upped it to 1.456 (according to CPU-Z) and I'm running 420*9 *(425 not stable just yet)
I'll be able to run 3dmark so far....I think. Stable for a few minutes in Prime95.....
I know you all like the deviders, but just for fun, give 1:1 a try and you should get 450/475/500x7 with a lil ease. I did, review my recent treads.
Q6600 to 500x7 and 8 in 1:1 DDR1000 @ 4-4-4-10. 3.5GHz as 500x7 felt nice on air w/ ASUS P5K Deluxe. I will try it on this mobo just for the sake of knowing if the trouble is in the mobo set up and report back soon I hope.
It was ok for older versions of OCCTPT in deed, no worry
Here are entry level quad cores:
Core 2 Quad Q9300 2500 MHz 1333 MT/s 7.5x $266
Core 2 Quad Q9450 2667 MHz 1333 MT/s 8x $316
Core 2 Quad Q9550 2833 MHz 1333 MT/s 8.5x $530
To get only 3.6 GHz from the Q9300, you need 480 FSB.
And for the Q9550, a nice overclock would be 3.8 - 4.0 GHz, which needs 447 to 470 FSB
All these clocks can be reached with the actual Q6600 G0 with lower FSB
No motherboard can actually support in a FULLY STABLE way a +450 FSB on a quad core.
Unless X48 makes a huge improvement in overclocking the FSB for a quad core (yet to be proved), the Yorkfield will be a bad overclocker due to a low multiplier yielding to either a NB or a CPU FSB wall.
The OC story is changing: the CPU now has huge potential, but Intel needs to optimize the chipsets as they did with their CPUs. Unless they do it, the NB will be a new limit in OC
do you see anything wrong with my overclock ?
I set everything to auto except for the multiplier and the fsb
http://i220.photobucket.com/albums/d...untitled-4.jpg
I know I could push it to 3.8 but I don't know how to mess with the ram , nb and voltage too :( I'm a total noob
Been reading through the last pages, but a bit unsure about what BIOS to go for, 0802 or 0903?
JH_man
i would say start with 0802 then see how much better 0903 is. 0903 is a noticeable improvement IMO.
whats your vcore electric_eye ?

you think i should give 0903 a try from 0901?
also one more question for you... all my cpu settings are disabled. maybe i could enable some of them, like speedstep for power savings.?
greets
I think if you're just starting out on a 09xx series bios, you may as well go to the latest one? I just switched over and IMO it's A LOT more stable and as some other users have said, "more fluid".
Guys a lot of good information is getting shuffled in this long thread. Kup has a good idea we should start compiling a list of Bios (check), Bios cpu/ram settings, general uses that will benefit anyone who starts reading this thread (preferably in the OP).
Cheers, Eastcoast! I just figured it would be a pain for me to track down older bios' for testing at a later date so I got as many as I could and saved them, and if I can help put other users, why not?
And here is the AsusUpdate that allows downgrading from the 09xx series.
AsusUpdate v6
Here is one example of some of the information lost in the shuffle:
-Check Asus website for bios updates regarding ASUS Maximus Formula and ASUS Maximus Formula SE. Remember there are not removable bios chips for these boards. You use any bios on this forum at your own risk!
-You get better N/S Bridge temps when you remove the factory TIM and apply AS5 Ceramic.
-When updating from one bios to another RESET YOUR CURRENT BIOS TO STOCK, NONE OC SETTINGS BEFORE FLASHING
-If the fusion water block on the chipset doesn't come off you can use a hair dryer to heat it. Or, you can cool the MB in the frig for a few hours in to chill the thermal compound. Either suggestion can damage your MB, you do this at your own risk!
-If you water cool the NB (SE version) it's best to use plastic clamps or worm drive, from Anandtech
-The black PCIe x1 port is proprietary for the included sound cardQuote:
Our biggest gripes revolve around the somewhat disappointing execution of the supplied water block design and unreliable 1/2" tubing clamps when using high flow rate pumps
-Yes, there is a 1.03G out there http://www.xtremesystems.org/forums/...&postcount=806
-It maybe worth the time to put a small 40mm fan on the s/b heatsink
-P5E is an excellent board if you are not looking for the features of the Maximus Formula
-Ultra 120 Extreme and clearance from the South Bridge heat sink using a 8800 http://www.xtremesystems.org/forums/...&postcount=920
-SE has option for 3 thermal sensors however you have to buy the thermal sensor cable separate
-Use a 8-pin 12V connector
-In order to get charted voltage results using OCCT, start Everest and go to:
-Preferences
-External Applications:
Enable shared memory must be checked
There is more but this is all I could find at the moment.
1.02G here :(
903 is still available at the mobo download page, here:

"-Yes, there is a 1.03G out there http://www.xtremesystems.org/forums/...&postcount=806 "
I'm not sure that's correct, there have been many purchases after that date of posting, myself included, none of the SE's have been 1.03g...
Chris
Agreed Eastcoasthandle. if you guys dont mind i can update OP with them tips and the links to bios.
Edit: pphx459, you only need 1.32 for vcore at 400 FSB? weird, I need to retest with this new BIOS... last time I tried 400 FSB, it needed a bare minimum of 1.38 otherwise things would go slightly odd, but I'm starting to believe that this was because I was playing around with RAM latencies too much. 0903 has put the latencies into perspective for me now.
ok,
i probably found why they removed the 0903 bios.
Unless im doing something wrong here, if in cpu configuration u enter a multiplier number (i.e. 9) and you want to change back to "auto" you canīt !! then you loose the speedstep option lololol of course going back to the main oc page the cpu will be 9 of course, and nothin else.
maybe this is not such a major problem, but its irritating not being able to go back to auto settings as an option.
You guys think i could keep the C1E state on to save power on low cpu loads, or just disable it.? any loss of performance on the cicle it takes the cpu to enter normal 9x mode from 6x.?
greets
Seconded. I own the non-SE board and it is a revision 1.03G.
Wow, I am having a helluva time getting my system stable. I got a stable 30min blend test with OCCT at Grnfingers 450x8 settings ONCE, but I could not get a 2nd stable run. I'm air cooling with the TRUE and a Scythe 63 CFM and my temps seem very high. I routinely hit ~68C with the cpu when OCCT load testing. I need to clear and reflash the BIOS I think and start again at 400x9 which I've also run stable before but now it's not wanting to work. I'm even thinking of trying to reseat the TRUE, although I did note that there was a temp increase coming from the earlier BIOSs to the current 901/3.
I had asked before for anyone to post their 450x8 stable BIOS settings. I've seen Grnfinger has started to run into trouble with his, which were at least a good starting point for me. I haven't exhaustively searched, but right now I've just got one BIOS template posted by Maglin on the 11/16 for some good 400x9 BIOS settings.
Since we're trying to consolidate info, would anyone who's able please post their stable 400x9 BIOS settings using the template here:

Thanks.
Here are some more interesting tidbits from this thread:
Below are some OC results using this motherboard with a Q6600 and E6750. I recommend that you make sure that your northbridge chips is below 47C before OC'ing. Also, as with any OC, you do so at your own risk. Please make sure you have proper cooling for N/s bridge chipsets as well as ram, CPU, etc before you OC.

-Yes, this board can handle 4 Gigs of PC8500. However, OC'ing maybe limited. Appears that newer bios address this.
-Those upgrading from a MB with limited bios tweaking (P5W DH for example) may find the tweaking settings in this bios daunting. Please review some of the OC settings listed above to get an idea of what needs tinkering and what doesn't. Also, if your CPU OC is not found it may be better to make a formal request for bios settings using your CPU then to frustrate yourself changing settings.
No Formula Maximus & 6750 OC?? :confused:
I'll pull together some of the Bios before 0404 if people want them.
hi quick question would you guys recommend the se version or the non water blocked version?
Thinking of watercooling but air would be easier.
Thanks.
This is good for bioses 0802/0902/0903 (These are the only bioses I have tested so far and haven't bothered with earlier bioses, however, it should work for all bioses so far released). Also, it may NOT work for you due to hardware limitations. Goodluck.
System Specs.:
Maximum Formula Rev. 102G
Q6600 GO (Low vid. of 1.2125 - needs low voltage overall but heats up quickly as you increase voltage. If your vid. is anything higher, you may need to add more vcore to be stable)
4x1GB RAM (2GB Team Xtreem 6400, and 2GB Corsair Dominator 8500s) If your memory is not capable of DDRII 1100+, then you may want to change to the 1:1 divider by lowering DRAM frequency to the next lower level in bios, in this case DDR II 900 (noobs) :)
Note: I'm watercooling my CPU, Northbridge chipset, and Southbridge chipset on the same loop; in the following order, Pump -> CPU -> NB -> SB (CPU->SB->NB should be best but I had design problems :) )

Thanks Zucker2k, and giorgos th. for some more settings to experiment with.
Question. I'm going for an air-cooled stable OC. I have the non-SE board so I don't even have the fusion water block. I've reseated the heatpipe using MX-2 thermal compound on the NB and SB. At stock, unaltered BIOS settings Everest reports my NB temp as 43C with 1.36 NBvolts. Any time I try to raise the NB voltage to accommodate an overclock my NB temps get up to ~51C. Is this higher than it should be with air-cooling? I haven't yet directed a fan at the NB, and I'm wondering if I reseat my TRUE on the CPU to a South->North orientation as opposed to the current East->West if that will draw a bit more air across the NB. Is that NB temp just wrong? Do I need to try and reseat the heatpipe?
Thanks for any suggestions.
I know the fact that I still have my week24 e6700 is funny to you, but the laughter is hardly necissaray.
I could :rofl: at your x850 XT or your Thermaltake Water Cooling Kit, but I won't. That would be distasteful.
I will :rofl: at your avitar, that's nice.
Thanks, it's actually a 10x multi so I don't think the board will be pushed much. I've had little luck bringing the multi down on this chip, bt I'll try since i ned to get this board ready for a quadcore OC in January.
Yep, sorry I didn't clarify. I am still using bios 0505. I just got the board (non se, rev 1.03g) recently to test several Q6600's and to test Crossfire. Haven't had a chance to play with memory settings and the bios' out there. One of my other q's needed 1.38 and above, try maybe just testing the CPU.
So I'm getting ready to purchase new ram, my G.Skill 6400's can't really do anything higher than 900 so was wondering if the 4:5 divider is working now. I've been following this thread since the beginning (I may just be blind) but haven't seen anything about this one.
Thanks again Zucker2k. I've got a Zalman FB123 w/the included 92mm fan that I intend to point at the NB. I think in order to do so I'm going to have to re-orient the TRUE to the S->N to allow some room for the Zalman fan. I don't have an active solution for the SB at the moment.
How do I even go about this? I wasn't laughing at your CPU, I didn't even notice the cpu model in your sentence, I thought you were actually being sarcastic with your remark - like asus will actually build a bios around an individual customers's cpu woes. No offense meant.
By the way, I own 2 E6700s, 1 ES, and 1 retail. I don't think they're anything to laugh at. I won't even laugh at a 486. People on this forum don't laugh at other people's hardware. When I see a 386, or a 486 all I'm thinking is how to make it ran faster, etc. etc. etc.
Hi, i have an Maximus ofc, and 2x Raptor 36GB SATA and trying to install Vista 64bit, i have enabled RAID in bios, and made both the disks to a RAID thingy, both are working Member Disks, it sais "RAID: INTEL RAPTOR" in bios, since i named it Raptor, but Vista dosnt find any hard drive to install windows on, do i need to download any files to my USB and try to load them so windows can find my raid?
Please Help //wreckage
Edit: What did you guys do for it to work with Vista? I see in alot of signatures that you have Raid 0 with Vista 64bit for example, but why am i having problems? My raid worked fine on ASUS P5W DH Deluxe X975
I was just going by the comment that "Also, if your CPU OC is not found it may be better to make a formal request for bios settings using your CPU then to frustrate yourself changing settings." Knowing Asus or who ever would't waste their time with me, I thought the xtreme systems members might have some advice. It was actually my way of asking people like you for some advice on settings.
I wasn't offended or anything, just saw an opportunity to give you a little good natured ribbing :stick:
As I said in my post, I don't even have my board installed yet and reading this thread being the novice that I am, all those bios settings are starting to intimidate me.
I guess I'll figure it out as I go along. At least RAM is cheap these days incas anything gets fried. :D
Gotta be a Bios setting, jumper or something hardware based. Vista 64 should be just fine with RAID 0.
i need help i just updated my bios to 902 and now i cant overclock nothin but it wont let me go back to 505 because it says its to old how do i get it back??
Good natured huh? :) You got personal there for a moment, but no problem, I love my x850 :), plays Crysis, COD4, and GRAW II, etc. I owned both an Ultra and HD 2900xt but returned them. I will probably be getting two 3870s soon. Should be fun.
Back on topic. The best way to get help is let members know what hardware you've assembled for your build.
Hi people,
I wonder if anyone around has a G0 vid 1.2875 with a full bios (now im on 0903) tweaker list for 400fsbx9multi... full air mobo?
my corsairs suck, thinking of upgrading to Transcend DC Kit 2GB DDR2 AXERAM PC2-9200 TX1200QLJ-2GK which are easy to get here.
not in 3.4 or 3.6ghz league yet,
i just started playing for 3ghz, but having a hard time going to 3.2... im looking for a starting point from 3ghz for cpu/nb/fsb volt, etc..
thks a lot in advance!
Read a few posts up. I believe EastCoastHandle posted the utility you need. Once you install and fire up Asus Update (the utility), check under options, check the option to "make bios downgradable", then locate and flash your desired bios.
Obviously you do this at your own risk!
I can confirm that cpu ratio is locked in 0903 bios.
\Edit not locked just very ...strange..Cpu ratio [08.0]
OK, so what's been happening is I have no problem OCing this processor with enough volts and propper cooling (cooling in sig, last OC on my 680i was 375fsb, 10x milti @ 1.64v), but it has a real hard time with lowered multi's and high fsb. I've had it on a p5w dh, p5b and 680i and same results for all of them. It might just be a processor thing, but I want to get a good fsb OC on this board to get ready for a quadcore (I'll be getting one in Dec or Jan and whatever quadcore I get, it'll reequire a pretty agressive fsb OC)
What's the best way to go about this or will I likey just have to wait til I I get a different processor?
The problem you're having isn't the CPU it's the boards you're using. 400+ with the 9x or 8x multi is putting a lot of stress on the board. Only the best earlier boards or the top end boards did it ok.
Something P35 or upwards would be ok? I think on the Maximus you'll be more than ok with 8x450MHz... Try these for starters...
