[JPxM0Dz]

On my second Maximus and have the same issue as the first one I rma'd

Getting...

CMOS Ckecksum Bad
Press F1 to run setup
Press F2 to load default

Hitting F1 or F2, clearing cmos and removing battery has no affect and cannot get into bios at all

Swapped out both sticks of ram, ran one stick and both, no affect

Hardware in my signature

Anyone know what's wrong ?

Thanks in advance

"CMOS Ckecksum Bad"

Don't you get that the first time you startup the MB with unset BIOS? Still tells you that after loading default and saving/exiting? Tried updating to 0505 BIOS?

I can't get that far to even update latest bios

You can get into the BIOS right? Go to Tools-ASUS EZ Flash 2.Page 4-38 of the manual. I would guess you just need the BIOS file on a floppy.

so when you press f1 or f2 it doesn't go into the bios? is your keyboard working for sure??

[ShawnTRD]

or I see a ALT+F2 to enter a flash utility on the splash screen

Figured it out guys!

Was related to the built in hub on my Tarantula KB

Thanks

Poo, I must be doing something wrong, I can't touch your memory timings, even at 339 x 9. What's your detailed bios settings please..
Chris

400 x 9
ram strap 1066
load line on
1,36Vcore
2,32Vdimm
The other setting on AUTO
and work all!

Hi, thanks Langley, I'll give that a try when I get home. Not holding my breath though as I've tried different settings yesterday and I only managed to boot into Vista for 5 mins before it bsod'd on me..

Samurai can u post the detailed settings please?

for my 3.825? it's 425 x 9, i started with the voltages in the high "normal" range that the user guide suggested and then just moved them back from there till it became unstable and went back to the last known stable setting. dram voltage is 2.0*. my ram is 4-4-4-12 with a 1:1 divider. everyboard seems to be reacting different. i can't seem to get too far with the FSB for some reason. tried everything that i can think of as well as others thoughts. i'm waiting for a better bios now. i'd like to get a nice solid 4.*** cpu clock with my 4 gig's of ram in there. we'll see what the future has in store shortly.

Is there any benefit of enabling trans action booster over static read control,

If I disable it on my board I can run 450FSB ( 450 x 8 ) with less than 1.4 NB volts (prime stable), I seem to remember from my P5K Dlx that some users had equal ram bandwith with static read control enabled and transaction booster disabled...

Any input on that ?

I would leave them disabled, they are only a stability annoyance.

Yeah those are the ones i have, great set of memory, can do 550 mhz 5-5-5-15 2.1v no problems.

[grimpy]

Thats alright then got the same kit coming tomorrow.

[GAR]

OK, 0602 Bios installed now, seems to be the same as 0505......i still have the P95 load issue with volts over 1.5...........ummmmm i didnt check to see if divider 4:5 was fixed, if someone could check that would be cool............other then than cant see any difference.

I can't boot yet at 1200MHz with my Ballistix PC8500.

This BIOS is BS.

[Leeghoofd]

400FSB here now with 1002 on the ram works fine here, transaction booster disabled and static read control on auto... NB at 1.3 volts, ram at 1.90 set gives about 2 volts they need according the bios readout...

Gonna try to get the heatpipe structure off, Nb temps at 49°C now SB at 52°C, hope to squeeze a few degrees off...

Hi, tried that, bsod into vista citing FLTMGR_FILE_SYSTEM, any suggestions?

Are you sure your CPU only need 1.36 Vcore for 3.6ghz ?, have you tried with an 8X to rule out the CPU Vcore...

I can't find that bios anywhere on their website. How did you find that? I'd like to read the bios notes first before flashing it.
