What is wrong :(

You should include your CPU type with your results. Your numbers are pretty average.

[XtraLongChiliCheese]

its a LOW AMD x3 720BE , but i unlocked the 4th core and i overclocked from 2,8 ghz to 3,0 ghz .

It cant bE :D

[gaslampcomputers]

I would expect slightly better results given OC, but your numbers fall well within the range of reasonable results. If you filter the results page for only 32-bit benchmarks, you actually perform better than average.

I just ran prime95 and looked at my results what else can I do with the program?

[gaslampcomputers]

@numptybaws3 You can join the Great Internet Mersenne Prime Search (GIMPS) and donate your spare CPU cycles to search for very large prime numbers. I link to the GIMPS site in the info.

Can i overclock my Core 2 duo E4500 on D945GCNL ?? Pls reply ... I want to increase the speed frm 2.2GHz to atleast 2.6GHz...

at 00:41 does he say this is the home of the gimps project? XD

[demonsparkx]

is it bad that my cpu only peaked at 51% load?

So i ran prime95 at the test just stressing out the cpu and when I woke up in the morning I see that my computer is on however, when I move my mouse I see the login screen and I log in and it feels like everything is starting up again however, I look at the results and there is no word on it failing how do I know if prime95 failed or did it finish completely?

@McPePsii what's your cpu voltage? I just got mine down to 1.30volts at 3.8ghz on a shitty Hyper N520. Lowering you Vcore helps temps A LOT. This CPU is beast.

What is your CPU volt at? Try 3.8 at 1.35 volts then go down if you can.

[McPePsii]

@rsx123 When I did it I was either on factory setting or I might have changed turbo to 4.0 either way its not a big jump

[rsx123]

@McPePsii What's your core speed?

[rsx123]

If you have an aftermarket cooler, put a 120mm fan maybe 4-5 inches away from the intake. I dropped my temps by 7-8 degrees doing that with a CM N520. Fucking amazing. I'm at 3.6Ghz at 1.35vcore on a PII 955 BE with a shitty fucking cooler. Couldn't even get 3.4 without the fan trick.

[SuperMangn]

My standard i5-2500k scores the same as an average i7-2600 and more than an average 2500k overclocked by 30%.

hey guys... been running this off and on for the last few days checking my cpu...

anyone out there, im looking for a STABLE OC... got a intel core quad extreme (qx6800) stock is 2.93ghz, its on 3.2 right now, how high can i go and where should the voltage be?? using a antec freezer 7 pro cooler...
