Ive recently been having loads of issues with overclocking my 3800+. Basically, Orthos failing after 2-3 mins and games showing corruption and lock ups etc.
Ive reset my A8V bios to default, and then tried 1.3v which didnt boot. Then i tried 1.325v which also didnt work. Finally, at 1.35v it booted fine and all was ok (orthos stable for around an hour) and it has always worked at stock so it was all ok. RAM is left on automatic voltage and settings, as i am running 4 DIMMS and so it automatically uses a 166mhz divider and 2t commands as far as i can remember.
However, as soon as i get to 2250mhz i get orthos failing (on the memory i think) as when i run the CPU test it seems to pass no problem, whereas the memory fails almost instantly. Now ive checked the timings which are rated at 2.5,3,3,5 at 166 which they running at so that shouldn't be causing problems. The ram is rated at 2.6v but i have tried running at 2.7v and 2.8v but with no difference. I've dropped the HTT to 4x from 5x and so it is well under 1000. I then upped the CPU voltage to 1.4v which i thought would be plenty for a 200mhz overclock and it probabily is (as i think it is the ram that is failing). The AGP/PCI lock is at 66/33 as the higher one causes the system to fail to detect my SATA hard drive. (73/something)
I've also upped the AGP voltage from 1.5v to 1.6v but that doesnt seem to make much difference. However, there is a v-link voltage that is currently on 2.5v but can also go to 2.6v, but im not going to touch it unless you can tell me what is it.
CPU temps are pretty hot at around 38 deg idle with an artic cooling cooler (not the pro one, the old school one
) but i may consider applying some new paste (AS5) if you think it'll do the job.
What would be a safe voltage to give this CPU on air. I'm not happy going over 1.45v if im honest, as i was led to believe that it was a 1.3v CPU and that you should only go and extra volt and a half on air.
What else can i try?
Thx

I think because x4 DIMMS are being used it's putting more strain on the motherboard and limiting your overclock.
