NEW TO AMD OVER CLOCKING

[dud54759]

Have not overclocked amd's since the 939 days and have forgot allot of info and what means what.

Trying to push this thuban up to 4.1-4.5 stable but cant get much over 4 before i start getting bsod etc.

So where is a good starting point voltages etc. Is my ram just to crappy to push higher. Basically i have played with multi and fsb settings but have not got very far.

I have yet to see 1100T go over 4.1 mine hits the wall at 4.2, most stable I got mine up was 4.125, and it's been agreed that it's maximum bench speed you could get without doing some insane tweaking or going N2.
I could give you my settings, but for every PSU/BOARD/CHIP it's way different, mine clocks cold and under factory voltages to 4.0... yours might not.

throw out some settings. i though these where capable of close to 5 guess not.

Ok, apparently I lost my 4.125, here is 4.0 that I have been running half the time:
CPU BUS: 200 mHz
CPU Voltage: 1.425
NB Voltage: 1.300
DRAM Voltage: 1.425 (now, this is 1.5v ram, and for some reason it works better undervolted, don't ask, but I did check it with calibrated multimeter, it is really the voltage)
CPU Multiplier: 20
NB BUS: 2600 mHz

give these settings a shot, you could probably dial cpu voltage down a notch or two... I have it flooded for stability test.

Is there any real world reason to jump up to the BD 8 core or 6 core? other than peer overclocking fun?

multi-threaded apps. But honestly I would wait if your current CPU is working for you. Let other people be the early adopters and testers unless that's something you want to be.

BD sucks, end of story, but here is a catch, FX8150 is a "high end" and per cycle efficiency been stated has 20% drop across the board, I'd love to render some serious overprocessed light scenes on that chip, that would give you real world benchmark.
however, there's been many crossed fingers, that AMD will release something of a black edition BDFX chip later, that we can clock trough the roof and generally higher clocks and wider voltage/stability band. let's pray they will.

For the most part, you can only get a Thuban stable at 4.2GHz+ with a high quality water cooling system.
The chip doesn't respond well to high voltages and heat, be happy if you can do 4.0GHz on air or a Corsair Hydro cooler.
Looking at your sig, your weak link will be GTS 250's in SLI, maybe it's time to upgrade your GPU's.

my gpus have ZERO effect on my overclocking lol. They suit me just fine i dont game much and i only play old crap. I see zero reason to spend 500 bucks n a 580 or whatever the hottest card at the moment is. 90% of pc games are console ports how sad is that. Went from doom 3 that will suck your wallet dry to rage.

So why even bother overclocking your 1100T?
