Duron 1.8

[cmatt680]

Hey here is my oc as of right now with just the bios flash. a 1.8 GHz Duron running at 2027MHz air cooled running at 43C at full load and 37 at idle. Is this good.

decen't OC, but not that good, some people get 2.5ghz(rare, but happens) and like always on this forum, more info is great. Waht ram, mobo, heatsink/fan. Thermal goop? What's your Vcore? Tell us more, but that is a decent oc.

Depends on cooling, power supply brand, etc, list your full specs so we can talk.

You need to test it for stability using Prime95 like so
est the stability of overclocked CPU, download the latest bug fixed version of Prime95:
http://www.mersenne.org/freesoft.htm

Double click on PRIME95.EXE to start the program.

Just Stress Testing (if prompted) > OK >
Options > Torture Test > Blend (if prompted) > OK


The program should not give any errors.
It may be necessary to run the program 12-24 hours to make sure an overclocked system is stable (no program errors displayed).


If you get errors only after several hours, this is a result of slight instability because the system is running with little or no margin. It's stable enough to boot and to be moderately stressed, but as soon as the system is under enough load to go over that critical point, it will freeze. To be 100% stable, Prime95 should run 12-24 hours without any errors.

The point of testing is to see if you get errors or not thus testing the stability. The meaning of errors themselves is not as important.


Running Prime95 Torture Test for 5 to 30 minutes is enough to get a feeling about general stability. If it seems to be stable, increase the FSB (with 0.025V Vcore increase if needed), or increase the multiplier by 0.5.

Reboot and run Prime95 Torture Test for 5 to 30 minutes and repeat this until the Program displays errors.
It's then time to back down and repeat the Torture Test until there are no errors for at least 12 hours.

It's OK to use the computer while Prime95 Torture Test is running in the background.


After finding your stable point you may want to then retest by going to the Advanced section, setting the password to 9876 and then setting Priority to 10. (You won't be able to use your computer while Priority 10 Prime95 Torture Test is running, but it'll confirm your system stability.)

Use 3DMark to test video card stability.

nice oc

Way to show off dude. :) BTW - the performance+ rating in your sig can't be right - Durons don't have one, and if they did, it would be adjusted lower because of the cache. [/Being a Jerk] Just kiddin' around. That actually is a pretty good overclock, especially at 1.78v. I've been thinking about picking up a 1.4GHz duron or something...it would make a fun XPC box.

A 200mhz overclock isn't bad, but telling us more about your specs would be helpful. Stabilty testing, like c627627 showed you, is absolutely vital. An unstable overclock can result in data corruption, and that's never fun.

Ok here goes, I have a ECS K7S5A PRO v5 with bios update that gave me more FSBs I have a gig of PC2100 v core of 1.52 an Antec heat sink and fan with Antec siliver thermal gel a 250 watt power suply
