Asus A7N8X Deluxe

[Fo_Sho_Bear]

Hi.

I've heard that my motherboard (Asus A7N8X Deluxe) tricks the CPU to think its unlocked, if this is true how come i cant change the multiplier? every time i do that the system wont boot...

specs:
Asus A7N8X Deluxe
AMD Athlon XP 2200+
ATi Radeon 9700pro
512 PC2100

is your CPU the revision or original Throughbred core (or wotever it is spelt like) ???

Hmmm, wonder if I can get a valid page fault ???
these invalid ones are far too commonplace...

its an thoroughbred-A

I also have an Asus A7N8X Deluxe. Your processor must be a thoroughbred-B to be able to manually set the multiplier.

The A7n8X and all other nForce2 boards (IIRC) only unlock T-breds B.

it also may be your bios. I had the same problem and updated to the 1002 and now im ocing my heart out.

hehe okey im gonna update me bios then, just one question should i flash thrue the floppy disk? i had a MSI mobo before and they told me not to use a floppy when flashing bios..

edit:just flashed the bios using that util u get with the cd, worked fine now i can set the mp to 14x only bad thing is i cant get fsb higher than 136, so any ideas on what i can do? except buying new ram 😉 havnt tried mp from 11-13 yet tho..

have you tried uping the ram voltage. It may help you get to 166. If not then youll need some pc 2700 or faster.

hmm it helped a little bit.. but when i get close to 142+ the pc speech thing says system failed memory test, so i guess i need better memory then :/

try lowering the multi to 10 or so and going strait to 166. you may want to set your ram at 133 just to be on the safe side. untill you get everything else figured out.

doesnt work since i cant change multiplier to anything under 13 :/

Weei i just unlocked my CPU by doing this: http://www.lostcircuits.com/cpu/amd_unlock/ and it worked exellent! i can now change my multiplier to whatever i want

hmm just did some benchmarks with 166x10,166x11,166x11.5 and none of them really preformed better than my original clock settings 133x13.5 🙁 any idea why??

hmm seem to have got a new problem.. in bios all settings are normal but when i boot it says its only ~700mhz and in windows with cpuid it says multiplier is on 5.5, tho its set to 13.5, so either i messed up my board/cpu and have to get new one(s) or i can fix it by reflashing bios?

Same problem, but I made some more tests and an email to ASUS for a bad bios.

The fact.

1° phase:
I got an unlocked XP 2400+ for my A7N8X deluxe with BIOS version 1001G. The system booted regularly, but when I was changing the setting (multiplier or FSB) the system did not boot (even with higher voltages) giving me the message "Warning, the CPU is overspeed". In this situation was still possible to chnage again the setting in the BIOS to boot the computer. But if the changes involve the FSB (for more then few MHz) the system does not boot and, to start again the system, it needs to remove the battery and clear the CMOS.
The bios of my other computer mobo (an older A7V333) is much more advanced because when the setting is incorrect, the system the first time does not boot and turning off and on the power gives the possibility to return to the bios setting without the need to open the case and working on jumping batteries and lilliputian jumper in a forest of cable. I wrote to ASUS to ask the reason of such primitive system to reset the system and I am waiting for an answer.

2° phase:
I upgraded the bios to the 1002 version. This Bios does not recognize an unlocked processor giving to the multiplier the lowest value between the couple of values reffering to the transfer table(e.g. the 2400 works with the value 7x/15x and the selected value is incorrectly 7x instead of 15x). I tested a locked XP 2700+ . It works both with BIOS 1001G as well as 1002. But a minimal FSB increase cause the system does not boot with the consequent annoying procedure of clearing the CMOS.
Increasing the multiplier (even if the processor is locked I tried) hang the system with the message "Warning the CPU is....".
As consequence I am not yet able to overclock the A7N8X deluxe. Who was able out there to overclock this board, and which procedure he used ?


Principle of the highest harassment for engineers says: having two events, one bad and one favorable, with the same probability to occur, it is most probable that the bad event will occur

I think I know why your mobo doesn't allow speed changes... you have set some kind of watchdog timer, or speed error check that makes your system not to boot at settings different then stock.
