overclocking my 1800+ tbred b cant get through prime95

[eshtog]

I am running at 12.5 *168 = 2100
stock voltage on ram and cpu

I can only get through like 2 mins of prime 95 what could be the problem?

What are the temps and try upping the votlage.

about 35 celsius idle

what should I raise the voltage too?

I believe it's at 1.6 now. Try raising it to 1.625 or 1.65. Do the lower first.

I know default is 1.5, so ill try 1.6 and let you guys know

Your voltage is obviously way too low. 1.5v is the voltage needed for STOCK SPEEDS, and if you're very lucky, up to 2.0Ghz. You would'nt buy a car with a 1.2 litre engine and expect it to do 200mph with it. You need to increase that voltage to reflect the speed youre running at. With my 1800+ DLT3C I can do 2.2Ghz @ 1.65v stable, but for 2.3Ghz I need about 1.75v, still very acceptable. Stick your voltage at 1.7v and have a play around to see what speed you can get it up to, you should find that with your CPU 1.7v will go a long way, but if you want to hit 2.5-2.5Ghz youre going to need to invest in some seriously good cooling, I recommend nothing less than a SLK900A w. 92mm Tornado as you'll need to start using voltages of 1.8v - 1.9v, which isdangerous territory on air cooling.

Anyway good luck experimenting, but remember to keep targets realistic when overclocking, as it is easy to over step your bounds and damage your components. 🙂:beer:

well I raised it to 1.7 and the highest speed I cant get through prime 95 is 11.5 *200= 2300

I am pretty happy do you guys think thats a pretty good overclock?

Anything above 2.2Ghz is a good overclock.:beer:
