Asus M4a79 deluxe up close and personal

[SteveLord]

Another solid board from ASUS? =)

[Jethro]

So far so good! Benched at 3.99 last night! Anyone else clocking a 545/550?

[Jethro]

I have a strange issue with quad unlock, for some reason it messes up anything flash related? But otherwise ultra stable. Also cannot get triple core settings to work! Anyone else tried this with 2206?

[ptys]

or 2206 supports the Phenom II c3?

[I.nfraR.ed]

I don't know if here's the appropriate place to ask, but...is there anyone from you that use the board with watercooling? I'm interested in the possibility to remove the heatpipe, so I can place the NB block, without replacing the heatsinks from the mosfets and SB. Is it possible?

2405 BIOS is out, don't know what changed.

[ 2405 ]
----------------------
1. Fix the system may hangs randomly when adjusting VCORE/VDDNB voltages in TurboV with Cool'n'Quiet enabled.
2. Add a prompt string and small icon to show the current number of cores under Unleashing Mode.
3. Add a hotkey to enable Unleashing Mode in POST state.

Bios seems good! I still get adobe flash errors when in unlock! Otherwise ultra stable @ 4ghz......im stumped!

hi what is the best BIOS for my 940BE?
i use 4x2GB kingstone hyperX 8500 and windows7
i have tray BIOS 2206 but i cant past 205x18@3690 1.5Vcore.
in windowsXP with my M3A32 i was get 218x17.5@3815 1.47Vcore with 2x1GB crusial traser 8500
sory for my english

[afireinside]

I'll have to try the new BIOS... still on 2206.

Has anyone else noticed that DDR800 setting OCs better than DDR1066? I'm guessing the higher divider/ratio/whatever its called puts a greater strain on the IMC. Either that or there are more aggressive hidden settings that go with DDR1066

200*18=3.6 DDR1066 setting = fails OCCT consistantly
267*13.5=3.6 DDR800 setting (puts ram at DDR1066 speeds) = passes OCCT

Or maybe I just borked my chip because it used to do 3.7 at this voltage and that was before I lapped it and went push/pull on my TRUE.

[izallica]

If you use am2+ use divider 800, to get better oc, now i use am3 965be, it work well when i use 1066 divider

i set sb volt into bios 1.2v,but AOD report 1.35v in windows, it produce more heat, i must set manual into AOD to get 1.2v sb voltage
i think we don't need 1.35v sb voltage to make system stable on default or overclock condition.



anyone have same problem with me ? It is normal

Sorry about my bad english

I remember having similar issues with this board, and think it was dependant on what bios version I used.

Don’t have the board with me anymore to test it.

1. Fix the system would generate full-reset automatically when pressing key " 4" at RAID Option-ROM.

Unfortunately the Unleash mode is messed up, I can't activate all four cores, only three. Back to 2405 it's working fine.

[Jethro]

I use water cooling and i can tell u that pwm heat is the main issue when clocking this board i think water cooling the pwm would net the most gain

I get the same issue where sb is always 1.35v

Cant get fresh os install to go in quad mode get some crypto strap error
She is prime stable 3.85 1.5v 2660nb. She is stable at 4ghz 1.55 but Over 1.5v seems to hard on pwm and it will overheat also For some reason my cpu nb needs 1.375 to be stable which adds to the heat problem

Just ordered a new primary drive wd 500aaks and will try quad install again once it arrives

I'm on water cooling too, but pwm heat is not an issue if you put a fan on the NB heatsink. Now it's around 30-35 C, still trying to find out my 550BE@X4 limits.

Where did you find that SB voltage? In AOD? I think it's reporting a false value.

[Jethro]

Hmm i have 2 AMD stock cpu fans over my NB/PWM and that certainly helped. When in quad mode she seems to get hot tho. I have my new WD 500aaks here and im just waiting on some new cables and 120mm fans to redo my whole setup. Gonna reinstall OS as quad *hopefully and redo my custom case to a better push pull setup as well as get some more flow under the motherboard.

Yes AOD is what i'm using to monitor volts. Wasnt sure if it was reading right thanks for the tip. Odd you can set it to 1.2 and it sticks with AOD tho... hmm

It doesn't matter what I set in the BIOS for the SB, AOD is always shows 1,35V. That's why I think it's reporting a false value, or maybe it's not fully supported. Yet.

New BIOS arrived:

[ 2603 ]
----------------------
1. Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx

Edit: Four core runing fine, and much quicker RAID HDD initialization @ boot.

[I.nfraR.ed]

Hey guys Anyone had problems with oc'ing...I hardly make it run "everything on default". Every time I try to raise the HT Ref. Clock it boots, but freezes somewhere at the post screen and after restart the board resets its settings. I tried several bios versions, tried to swap memory modules to different slots, tried with one stick of ram also, but I can't make them work even at the rated 1200Mhz. I've checked with all my 3 CPUs - no difference. The unlocking is working although and it unlocked the second 550 to X3, which is more than i got on M3A78-T, the other one unlocks to X4 perfectly like before. I'm gonna try that last bios version (2603) maybe tomorrow, but the mobo swapping is pain in the ass with these waterblocks, because i have to detach them from the old board with the whole mounting hardware (springs and so on), detach all cables and reattach after that to the "new" board. Btw, do you have 1200 RAM profile? I don't have, but thought the board would has, because of the "O.C. 1300" thing on their site. Also on some of the bios versions it was mentioned that it supports 1200MHz DDR2 from that version.

I don't want to go to DDR3 board for now and one of the reasons is this

Update:

I managed to run it with the 24/7 settings I used on the old board, but for some reason it needed 1.5625V to CPU/NB for 2760MHz NB I used to make 2900+ on the old board with 1.45V ! This one did about 3000 with 1.65V, damn...too high. And it was impossible before i switched the position of the CPU_OV jumper. There's another thing - NB voltage max value is 1.4V, but on the old board I could increase it to 1.6. Probably I don't need it, but...

new bios 2708

memory seems real sluggish on this tho anyone else tried it ?

I've got no problem with it.

[ 2708 ]
----------------------
1. Fix the system may hang at OS LOGO when C1E/EnergyStar5.0 is enabled in BIOS with certain CPU.
2. Add two items at chipset\RD790 Configuration\PCIE Configuration to configure PCIE_X16_2/PCIE_X16_4 as X8 mode. This fixes any X4 devices plugged on these two slots is treated as X1 devices.
3. Fix the floppy control is still shown in the Device Manager when floppy drive is disabled in BIOS setup.
4. Remove "GFX Dual Slot Configuration"/"GFX 2 Dual Slot Configuration" in BIOS setup.
5. Fix the system hangs at OS shutdown when overclocking CPU with AOD and enabling EPU function.

[afireinside]

I feel like I'm flashing a new BIOS every other week... I'll give it a go later.

I recently (after 11 months of ownership) put a fan over the PWM area. Just a small 60mm stock AMD heatsink one. Not sure if it made a stability difference but I finally took an IR thermometer to the mosfets and they were running ~190F under OCCT load

[Jethro]

No problems here running great! Seems very refined.

2405 best bios for me to run ddr1200



bios 2206,2502,2603 have failed @primeblend stability
