Overlocking issue

Last response: in Overclocking

My config:
AMD Athlon64 X2 6000+ 3GHz (with Asus X70 fan)
ASUS M3N H/HDMI mobo
2x2GB 800MHz Corsair RAM in Dual Channel
Coolermaster Silent Pro M600 PSU
Welgate 160 GB SATA
MSI HD4850 512MB
ASUS VH242H LCD monitor

The RAM although is 800MHz, runs 750MHz at this state... I tried Overclocking CPU using Bios settings and achieved 3.3GHz(10% Overclock)... now RAM speed changed to 825MHz. Why is it so?
Also if i play games at 3.3GHz, system hangs in the middle of the game..

Have you stress tested after you overclock? Made sure your CPU, GPU etc. isn't overheating?

How'd i 'stress test'?

If your overclocking and don't understand how/why your bus/RAM speeds change, or don't know how to stress test, STOP OVERCLOCKING. Not only will overclocking void any warranty you have/had, you can DAMAGE the devices in your computer. Do more reading, ask questions, but don't just start changing values in the bios.

You can stress a CPU by running an instance of Prime95 on each core. (info is here. http://www.playtool.com/pages/prime95/prime95.html) You might also want to run memtest86 as well.

*** N SAFE THe worst that can happen is blue screen or crash bios , =D just dont touch voltage if u dont noe what u doIng once again above person is retart / point retart

Actually, that isn't true. Many motherboards (mine included) will happily push voltage to levels that are well above the recommended maximum if you overclock with the voltage on auto.

Yes, indeed. Among the many things you need to know (including overclocking and thermal management) is what settings you can leave on AUTO, and what settings you need to change.
----------
Overclocking since 1978 - Z80 (TRS-80) from 1.77 MHz to 2.01 MHz

I'm doing it in Bios(Asus M3N-H/HDMI has such options like Overclock 1%, 8%,10%).
Voltages and other settings set to 'Auto'. RAM frequency set to Maximum Clock.
At 10% Overclock, CPU charges to 3.3GHz from 3GHz. And RAM's each 412MHz(i.e, total 825MHz). When no Overclocking is done(At 3GHz), RAM speed is 750MHz. I think it need to show 800MHz at no Overclock(coz. they are PC2-6400 RAMs).

With voltages set to Auto they go up to accommodate the Overclock (ie... CPU,NB,memory), building heat. So as always keep an eye on temps!!!

+1. Prime95 is a very popular overclocker's stress tool.

Checked with Prime95... At no O.C state, successful...
Failed at all Bios Overclocking modes..

well, the reason the ram isn't running at DDR2-800 with your processor at stock is because the ram speed is tied to the cpu speed, you have to take your cpu **** and divide it bye the muliplier divided by 2 rounded up (so 15 / 2 (rounded up) = 8, 3000 / 8 = 375 or DDR2-750)

If it fails when overclocked, thats why it hangs while playing games. Now you need to figure out why it failed. Could be heat, could be a lack of voltage, could be ??? Have fun.

I've enquired about Blue Screen Troubles at Asus Technical Enquiry dept. They say my mobo and processor are not compatible with each other... I'm using Athlon64 X2 6000+ Windsor(125W) on Asus M3N-H/HDMI. They say its not compatible with 125W version... only compatible with 89W version of the same processor.. Well..i've read technical spec on M3N-H/HDMI as, it support 125W processor.

Go get a phenom ii and stop wasting time with that electric heater.

That could be the problem. If the motherboard only supports up to 89W CPUs and your using a 125W CPU, then overclocking, the motherboard won't be able to handle it. You said you can run it stock, do that until you can afford a better mobo/CPU.

In Asus website, specs show mobo support upto 125W....

Thats why i choose this processor... and now ASus technician report that the board don't support 125W..

I'm not sure why they said it won't support it, as you can run it stock and it says it can. I still get the feeling that although it can run it at stock, overclocking is stressing the board to much. If 125W is right at the upper edge of what it can do, it won't be able to handle a 125W CPU trying to suck even more power in OC'd mode.
