My cpu can do 213x12 at 1.87v and it won't get unstable till 59°C. Though it will get unstable at 214x12 the second it hits 50°C. |
Exactly, I can't add anything more - the CPU's temperature seems to be some "magic" factor while overclocking and it's always good to keep it beneath 50°C. All those readings come from socket and not from the CPU's thermal diode, so they must be lower than in reality, especially under heavy CPU's load /stress.

And be careful on what you buy. A 420 Watt PSU of no brandname might as well be as crappy as the one you had before. It costs much less but lot's of OC'ers buy the moderate priced component, then hungering for more power end up buying the more expensive one.

I can't disagree!
As to booting - Merlin's bios has a so called "cold boot issue" - you can reboot dozens of times and everything is fine as long as you don't shut down your system. Mobo won't boot then, until you turn off your
PSU for a few secs and turn it on again.

As to the problems i have had, it seems i'm once again stable. The S3 and AGP aperture size of 64mb seem to have done it. I haven't crashed since i tried those settings. With the booster again in place. Though i used to be stable using 128mb aperture size together with the Merlin taipan mod bios before i tried playing with the booster. Now it won't seem to do that anymore at exactly the same specs as i had before, as still in sig. With the booster and 20 pin ATX cable extention for the booster plugged out. These strange things keep sneaking up on me with this board  |
Well, huh, what can I say - strange, wierd, magic - I've never heard of any similar situation, in which AGP aprerture size would have an influence on stability. Must check it on my PC, although I don't see any logic in this
cheers, mate
