Hello I have an A7N8X deluxe with crucial PC2700 cas2.5 ram. I am using XP1700 thoroughbred B cpu. 430 antec truepower psu. new 1003 bios I am using

My problem is that I was Folding proteins for burning in of my computer at 11.5x151 and after i finished my first WU I wanted to see if my memory had gained any performance from it so I decided to test the FSB limit by using the 10x multiplier and moving the fsb up. I tried 10x175 and it booted fine. Then I treid 10x180 and it booted again. I finally tried 10x185 and no boot. So I said hey there is my new limit before hand it stopped booting at 175fsb. When I went to reset cmos jumper and reboot computer I received no video but the monitor initiatized that there was a connection by saying power on- power save but no boot up sequence. There was no beep that I usually get when the ram test starts. Then I started to sweat really hard. What did I do!!!!!!!!!!!!!!!

I tried changing the memory to different dimm slots. I pulled out the battery and reset cmos, i changed battery from one in soyo dragon to no avail I don't see how that week of an fsb test overclock could have hurt something. Somebody on the forum when I searched mentioned to somebody who had my same exact problem when he booted at 11x160 told him he took out the battery and set jumpers to reset mod and left it to that for a week and it fixed everything. Why would leaving it like that for a week doing anything?

Sorry for the long message. If I get anymore work up I think I will cry. I also tried two differnt types of memory. I haven't tried a different cpu yet but that seems to be my next endevour. I kinda hope it is just the cpu because xp1700's are cheap and this mothorboard is not! Thought this motherboard and would end my K7S5A problems with boots but I guess I was wrong it is just computers. Hopefully I won't loose my desire to overclock after this.

Any help would be appreciated!!!! Thank You!!!!

when you turn the power on, yet hear no beep (assuming the pc speaker is connected) it could be the cpu. if you hear a beep its not the cpu. if you havent tried that already, remove everything connected to the motherboard, and leave a video card and 1 ram stick on it. then power on. if you still get no beeps something is really wrong. also try to remove and reinstall your cpu. i hope this helps

I took the cpu out of the computer and started it up. Lights,camera, but no action!!! no beeps only fans. Guess I have a big problem. Leaving me with a very bad impression on this board.

Edit:

What else can I do?:(

Yeah I did the exact same thing, this thread. (http://forum.oc-forums.com/vb/showthread.php?s=&threadid=187075) And this replacement board freezes practically every time I exit bios, the little red squares thing (166X10.5 relaxed memory timings). Makes me paranoid to go any higher, but i'm getting kind of tired of yanking mobo's in and out RMA ect, (first one rev 1.04 had a defective floppy controller) but I'd like to make this board work, whats anyone think about flashing back to 1002A? Or is it the chip itself?
One things for sure, if I can't get satisfaction out of this one it's on to Abit NF7 most likely.

Somebody told me that the nforce2 chipset and bios are just far from being perfected. Stability in overclocking is a luck of the draw kind of thing. I wasn't too lucky myself. I did this exact same thing last time and went up to 10x175 and couldn't boot and reset cmost work perfectly but 10fsb higher after burning in and the thing dies on me. So is that ABit NF7 pretty cool. I don't like being held off by computers that have the constant same problems with no fixes in the future like my old ECS K7S5A motherboard. That was a budget board but I can say one thing out of three motherboards in here that is the only one is two of 5 that have survived my overclocking tryouts.:rolleyes:
