Maximus Extreme - Results/Info/Bios

[GLENBOY]

glad to see your in the maximus club the 803 bios is a lot better than previous , just superpi'd at under4.2ghz at 1.6volt , with the other bioses i needed around 1.65 volt just to be stable over 4ghz so whatever asus has done has done the job, if you get an error with pc probe after a crash just reinstalling it solves it, loadline calibrator works rock solid shows slightly lower values than reported in bios but rock solid and never moves, not a lot more time tonight to play about with it but seems a winner to me

New bios plays well with yorkfield. 4.4 Ghz on water and I haven't even started pushing it yet:



FSB Term overvolting issue I had before seemed to be a function of early bios; with latest bios FSB Term drops around .04v for me from bios to actual, according to PC Probe.

[GLENBOY]

nice one, only 1.504 volt as well is the load line calibrator working ok on the yorkfield

[Aivas47a]

nice one, only 1.54 volt as well is the load line calibrator working ok on the yorkfield

Yes the loadline calibration is working very well now ... vdrop is maybe .01v at this setting, with another .01 vdroop under full load. So far very pleased with the board.

hi,
i have a probleme with this board and corair dominator 1800 cl7
i have test every thing but i can´t run the ram on 1800.
450x6 ram1200 works perfekt
450x6 ram1800 don´t work
the problem is that memtest says 0 errors but 3dmark and prime hangs on at 5-10sec.
i have test bios versions 701,702,802,803 and nothing works.
i have test default settings and i have the same problems.
is the board bad or the ram? or are you thinking that the cpu are bad?

sorry for my english.

greetings kowa

hiya kowa
what speed are you running 3dmark at and what processor , i have the patriot pc15000 and can bench 3dmark01 at 2012mhz , the board tends to overvolt the ram according to pc probe i get errors on memtest when i run the ram at 2.0v but at 1.94 volt no errors,what volts are you giving the ram 2.0volt ? so if you think its the ram at fault slightly lower the volts on ram and try it

[kowa1981]

@glenboy
ich have a e6600
i have set 1,94v(real 2v) because when i set it to 2v it becomes 2.06.

i become next week a q6600 pretested @ 4,05ghz (450x9) stabil.

bios settings:
all settings are the maximum that i have tested.


cpu 1,6(real 1,56)
cpuvtt 1,65
fsbt 1,46
nbk 1,45
sbk 1,07 (real 1,075)
sb pll 1,52
dimm 1,94 (real 2), i have test 2v(real 2,06) but the same problem.
dimm vtt auto.
pci 110

cpu features all disabled.
temps from cpu mb gfx ... are ok!
cpu,mb,gfx,hdd are @ watercooling.
here a link to my system
http://www.sysprofile.de/id46864

edit:
i have test 1t and 2t. the same problem.


memtest works with 0 errors! everthing perfekt. but 3dmark games or prime hangs on.

kowa, honestly I believe this is an issue with the Asus X38 boards. I had a P5E3 Deluxe with the same 1800 C7 Corsair ram. It would boot at 1333 but no higher, no matter what timings or voltages I used. I knew the ram was good because I had used it on a P5K3, so I traded the P5E3 board for a Maximus Extreme. The Corsair runs fine for me on this one, but I have seen at least 3-4 other reports around the web (besides mine and yours) of folks having boot issues with Corsair 1800 C7 + Asus X38.

How is hot PCIe chip? I am building rig with this mobo, but i want to use my watercool setup and i have only TWO chipset blocks ... ONE for NB, ONE for SB ... is it necessary to active cool that IDC chip?

[Infa]

Dont know how warm it is, couse there are no sensor for the crosslinx, that im guessing that you mean, but putting my hand on the BLue cover, it feels pretty warm.. NB keeps around 40ish MB, that may be the PWM, keeps lower than 40.. SB around 40 too.. and this with a fan blowing over the Sinks.

it gets pretty warm, even if it works the fuzion are the way

[OBR]

i need to know how hot is only PCIe chip, not with SB under blue heatsink ... but only way to test it is disassembling of cooling system and touch the IDT chip ...

big thanks. now i have my q6600.now i can run it @ 9x425 and the ram 1700mhz 7-7-7-20 1t prime stable. i test next weekend more. i report the results.
but with 1800 the board starts and windows too but not stable.
the bios version 803 is very very good.

I cant Downgrade the bios, Ezflash says its older than existing (ofcourse) but it should work anyway? been working all the time until this MB

You must have went to 0803 and want to go back to 0702.Just reflash with 0803 and interrupt the writing of the flash with the reset button.This board has crash free bios so put your disk in the dvd and a usb flash drive I a usb port with the bios you want it to write.Just rename it extreme.rom and you can go back.I have done it several times.

I have had this board for 3 weeks with a QX9650 and corsair 1800 C7DF on phase stable at 440x10 with the vcore on auto for some resone I cant raise it but I know it just a bios setting.

How much volts You guys give to the NB? I set it to"AUTO"and at 9x467 (RAM 934MHz at 7-6-5-15 / 2.144 volts) the board set 1.52. This was even not 1M stable...... - so I tried 1.55 now and 1M & 2M is stable, but 4M did not complete. Seems the board needs hi voltage on the NB - maybe I should try 1.6?

At 9x445 with the same RAM settings (RAM 2.000 volts) the board is 32M stable with only 1.44 volts on the NB. Makes me wonder......

Any ideas?

[Infa]

yeah these X38 seems weird actually.. in some things..

seems rather tricky to find out what will work..

[peterpiper]

http://www.anandtech.com/cpuchipsets...spx?i=3156&p=4 I know this link is for a P5E3, but the I linked into it googling the Maximus Extreme. Bios looks the same. Good Detail and suggested settings for a leg up!

Camo, my board definitely needs to have the NB voltage cranked up when the fsb gets up to 450+. At 10x400 fsb (yorkfield processor) I'm good with NB at 1.4; at 450, NB needs to be 1.61.

[Mitolo]

Yes all this info will help I hope as I should have mine in the next 4 days
Intel Core 2 Quad Q6600
ASUS MAXIMUS EXTREME
G.SKILL 4GB DDR3
Radeon HD 3870 ... X2
Creative X-Fi
PC Power & Cooling Silencer 750 Quad (Crossfire Edition)

hi,
i have a probleme with this board and corair dominator 1800 cl7
i have test every thing but i can´t run the ram on 1800.
450x6 ram1200 works perfekt
450x6 ram1800 don´t work
the problem is that memtest says 0 errors but 3dmark and prime hangs on at 5-10sec.
i have test bios versions 701,702,802,803 and nothing works.
i have test default settings and i have the same problems.
is the board bad or the ram? or are you thinking that the cpu are bad?

sorry for my english.

greetings kowa

Have you tryed the hotfix for 3dmark ???http://www.futuremark.com/download/hotfix_oct07/

[kowa1981]

thanks mitolo but i have this hotfix installed before.
the problem is that prime95 have the problem too.

i wait for a new bios. i hope that the new bios run faster...

Yep - have exactly the same, 1.61 to the NB for 9x467 SP32M stable.

DDR2 X38 on P5E only needed 1.43 to run this stable..............

[Aivas47a]

9x467 stable is a great result for these chips so far.

[peterpiper]

GF is making me stick mine under the christmas tree!! I'll have to wait another 2 weeks..sniffle, sniffle..

[Nosfer@tu]

Im having a HELL of a time with this board and the OCZ DDR3 PC3-12800 Platinum Dual Channel.

Running it with SS on CPU, Water on Nbrige and a E6850.
ALL the time when I change somthing in bios, it has boot problems.
I will have to start from scrats once more, if I cant make it run I will take some bios pictures just to make sure im not messing somthing up.
