Weird problem when I try to overclock my 3800x2

Hello,

When I had my old motherboard I could clock my 3800x2 to 2.8GHz with 1.4v no problem. It has a Toledo core. My old board was a GIGABYTE GA-K8N Ultra-9. Wasn't bad at all. That broke and I was refused RMA so I purchased a cheap(ish) K8N-SLI to replace it. I know it's not as good as the first one but it's all I could afford.

Anyhow, moving on. The old board, entered clocks and voltages etc. Saved and exited bios. Fine boots (if stable). No problems.

Now with my new board I go into bios, I set the fsb, the vcore and HT. I save and exit and boot but when it's posting it says "over cpu frequency" or something similar. That was what my old board did so I thought it was ok. Then I was expecting it to start detecting IDE devices but instead it restarts.. Then at post it says "skip over cpu over clock" or something much the same. Like it does when you press delete to go into bios at post but I didn't press anything. Then boots up as normal.

No matter what I try it does this and it's quite annoying. :(

The bios is latest version and I tried far lower clocks to see if that worked and no luck.

Any ideas?
 
Does amd chips like these have some sort of CPU parameter recall feature? sounds like this is kicking in.. maybe *shrugs* I'm no expert, look thru bios for option called "C.P.R" - i think disabling that should stop it - however if you push chip to hard it means you will have to manually reset cmos every time. well i think so :/ I'm making assumptions lol - wait for someone with a bit more brains on the matter i think :)
 
mine does the same u just gotta tweak the overclock lower, drop the memory to 133 and the ht bus to 3x and pump in two steps up on the cpu voltage
 
Yeah, if the HT is on 4x at 280FSB then the htt link will be going over 1000MHz. Drop to 3x and that'll sort that if this is the case.
 
I set the HT to three anyway and have tried with the HT at 4 and an fsb of 220MHz.. The same problem still comes up. :(
