I have an A64 3000+ cpu, K8N-E, 512 MB Transcend DDR 400 , BIG Geforce 6600GT , Powersafe 400W PSU. When ever I overclock anything, be it the graphics card or the processor, my comp hangs after a few minutes. :(

I overclocked the cpu for fun using the bios option "overclock 10%" which increased my cpu speed from 2000 mhz to 2200 mhz and HT. I ran some games and after a few seconds the game would pause.

After 25 minutes, the computer hung up. Even if I overclock my graphics card to and 510/1040, it hangs after a fews minutes. :@

What could be the problem ? It is not overheating as after a 3 hour gaming session my Gpu temp is just 59 C and CPU is 45C (stock speed). :huh:
 
The reason for the PC freezing when the CPU is OC'ed is coz the RAM would also have been OC'ed and it's unable to take the speed. Use a RAM divider before OC'ing the CPU, say get the RAM speed to 333MHz and then run the 10% OC for the CPU. As for the G.Card, what r the stock frequencies coz' Saiyan's BIG 6600GT came clocked at 525/1050.
 
Are you saying I should lower my ram speed to 333 mhz ?

My card stock speeds are 500/1000. Even a small overclock causes it to hang.
 
Do not used the stupid 10% overclocks and crap. Do a manual and increase the FSB but 5 at a time.

I did the same, it oc'ed my proccy to 3 ghz, but my ram was brought down to PC2-3200 standard :S.
 
Note:- before u try any thing i aint responsible for any sort of damage
caused to ur hardware u are completely responsible for what you do.
======================================================
Also check if the Cool n quiet technology is disabled before u overclock.
PCI/AGP bus is locked.

Are you saying I should lower my ram speed to 333 mhz ?

No not to run the ram at 333mhz.
Use Ram Divider so that ur ra mruns at slowerspeed than your CPU.
Use 5:6 Divider so that when your CPU runs at for eg 220 x 10 = 2200Mhz
your ram runs at 220 x 5/6 = 183.3333Mhz

Use Manual overclocking and increase ur HTT by 5 Mhz

This is understood :bleh:
 
Cool, I have overclocked to 2200 mhz and have set the ram to run at 183 mhz. Seems fine right now, no issues. Will check if there are any furthur problems and post back. Thanks a lot ! :hap2:
 
Good. But also check the PCI/AGP or PCI/PCI-E speeds as Quad suggested. Under Jumperfree Configuration u should have AGP Speeds or something similar - Set it to 66 from Auto and as for the PCI - Change it to 33 from Auto. This is important as u may end up frying ur card if u don't do that. And this could very well be the reason why ur AGP card kept freezing. The AGP frequency would have increased along with the FSB causing the card to lock-up. Change the AGP/PCI speeds first.
 
One more thing..

This doesnt concern this dude..

What if i increase the PCI-E bus speed to the max? will i get any performance improvement?

Whats the max btw on Nf4 its 145Mhz [if i am not wrong]
i would suggest not to change that freq keep it on whatever stock it is.

Also ask other ppl for there opinion.

Its 5:6 for sure [Am i really wrong]
Check if at stock its DDR400 i.e. 1:1 200x1/1 =200
at DDR 333 Divider it is 5:6 i.e. 200x5/6 = 166.67

Umm, atleast on my A8V its 5:3. After all you have a DFI :P
 
Umm, I checked the speed using NVIDIA SYSTEM UTILITY and it says that my AGP bus is clocked at 75 Mhz !

I changed it to 66 mhz in the bios, but it keeps reverting to 75. Any idea why it is so ? I managed to change it back to 66 using Nvidia Sys util, but it is for the current session only !
 
WTF, doesn't the NF3 chipset have AGP/PCI locks ??? That's strange. How abt. PCI ? Has it also increased in proportion to the FSB ?? And don't set it to Auto - Meaning the frequency increases along with the FSB exactly what u don't want.
 
If its an asus board, you need to set the AGP bus to 67MHz, to lock the PCI/AGP. Anything else and the lock doesnt work. Set the bus to 67 from the bios, bring down the LDT/Hypertransport ratio to 3, set the divider to 166 and then try increasing HTT.
