I think I kill 2 A64 in one night, need some help please!

[Trader88]

Hi all,

Let me try to keep this brief. I had been running my A64 3200+ 1MB L2 (its one of the early one) fine at 240 x 10 for more than 3 months. The detail is on my sig rig2. The setting was as follow: vcore 1.7v, vdimm 2.7v, vddq 1.6v, and ht default.

Couple days ago when I boot up the system, it posted but with a message "scanning harddrive for bios image". I wasn't freak out at all coz it happen before with single bios chip Gigabyte board. I figured my bios is dead. So I got myself an 8KDA3J, thinking this will fix everything and it¡¦s a much better board. Every other parts remain the same.

I fire up the system. Wow its even worst this time, no post at all. The system is power up alright with the on board debug display "FF". Cdrom and HD are on alright but search looping infinitely. I power off and reset cmos a few time but same result. I took out everything and reseat everything but same result.

I figured, I think this is the famous A64 death I encountered. Although didn't understand how it happen coz I'm not running high vdimm. Anyway, I have another 3200+ right beside me on a KV8MAX3 just finished building for my girl friend. It¡¦s still a clawhammer with 1mb L2 and its running fine on the KV8MAX3.

I want to try the new 8KDA3J so took out that 3200+ and slip it in and fire up.

Damm, same result. At that point, I was thinking it¡¦s definitely somewhere is wrong in this system. Suspected the 9800XT or the PSU. Could these have killed the CPU?

Anyway, slip back the fine 3200+ (I thought) back into the KV8MAX3..... ..... Now this is impossible......the KV8MAX3 system is now no post and siren non stop. Debug light shows "90". Not sure what that means and it¡¦s not on the manual.

So that¡¦s it, I think I kill 2 A64 in 1 night. Is this possible. Is this the famous A64 death?

Any thoughts guys help please.

I will try to test the PSU, ram, and 9800 separately to see if I can isolate the problem. Even if there are bad parts in one of those, could they have contributed in killing the CPU?

Sorry about the long story, and thanks for listening anyway.

IC7 is an Intel board, and how is he going to a get a new BIOS on a board that wont POST Without hotflashing or using a new BIOS Chip.

I have 2 quick question, hoping some of you could help out:

1) Can I assume no post is CPU death? Because I suspected it might be the 9800 that die. But it can't be, the KV8 system also no post, so it must be the cpu.

2) Does anyone know whats "90" mean on the KV8MAX3 debug?

Many many thanks

I got an MSI K8N Neo that wont post with my 9700pro ( any other card is fine )
So i think its NOT ure cpu , try another vga card

Fire up your system with only one HDD (with your OS) some mem and videocard and see what it does.

If it's a no-go try a different videocard and different RAM, still no-go, measure the rails of your PSU with A MM.

If all fails, take your new board+ both CPU's to the store you bought your new mobo and tell them the board killed both.
