on all ati hd48x0 cards I've seen so far, the max gpu setting available in overdrive (790 or so) seemed stable - no need to run the check :) So don't rely on the button to automaticly find the best frequency if the shader is linked to the gpu speed. So even though it'd run 20 minutes scanning for artefacts in atitool, a 3dmark test would crash at the nature scene when the lights were rendered. It could set the gpu and mem speed, but the artefact check isn't able to figure out if the shader speed is too high. So on oem systems you may not find the solution you were looking for in software.Īnd atitool didn't work very well with my 8800gtx. I suspect hp deliberately did something to prevent it from working. They might be brilliant in some situations, but they don't nessecarily work.įor instance on my work pc, a hp dc7800 with an e6750, setfsb can only read the fsb, it can't set it - no matter which of the 3 types I tried (mmt, slp and the other one). Regarding the programs - I have some comments on them. If you oc from windows, the changes being made are significantly less than from 0 to preset. That I assume is the reason that gigabyte boards shutdown and restart when changing such settings - to avoid the problem. When you're booting your system at an overclocked state, chances are your vrm's can't keep up at powerup for some reason I don't know. There are advantages to overclocking from windows too actually. This is true both because of effectiveness (some programs don’t display the frequencies well, for example) and because of operating system choice (the majority of the programs we’ve mentioned are only for Windows).' 'We’ll end with a recommendation: it’s sometimes better to overclock via the BIOS setup program. Only a theory, but I hope the information helps. Processor based on an electronic keying mechanism' Replacement of a storage device containing a boot-up executable code byĮstablishing a secure path between a secure boot device and a host in the patent which is 'a secure subsystem to prevent unauthorized I'm including the google cache for word reference as well as the original article:Īnother thing I found was the detail of the C.S. (Crypto Subsystem) on their chips runs at a certain clock speed.

One article from IBM discusses it as part of their CPUs.

I don't know if this will help, but I found a couple things regarding the Cryptographic Subsystem:
