my spec...
AMD X2 Windsor 5200++ 2.60 Ghz with AIR Cooling Noctua UHF12(i think - forgot the model number)
Kingston ValueRam DDR2 800Mhz 1GB (1 stick only)
Asus 7950GT with Zalman Full Copper Cooler
M/boad Gigabyte MS59SLI-s5 F7(bios update)

My pc acctually restarted on its own while overclocking till 2850 Mhz...
can anyone tell me why???
plzzz i really need some help...

System unstable due to overclocking...

Possible reason..
1. CPU overheated
2. PSU underpower

and alot more reasons....

if its about the CPU...
my cpu already Cooler Master iGreen Power 600W... dont seem logic my pc got underpowered...

If its about the cpu overheated.. while overclocking the temp only goes fot 40C max...

really need everyone help rite now

how much is the vcore and vdimm btw ?

the vCore? ermm 1.43 volt maybe...
about the vDimm i dunno where to find it

Definitely enough power from PSU. Probably not enough vCore very few Windsors are stable at 2.8Ghz without substantial voltage increase. Btw under what conditions did you take the CPU temperature? 40 is really low for your processor when overclocked on air cooling, unless you're talking about when its just sitting idle.

i tested with super pi 32M... it passed... but... going up till 3GHZ bang.. its restarted...

okay..assume that ur psu is okay and reliable to overclocking..
let see what things left and need to be considered;
- temperature
- vcore
- vdimm
- ram divider and timing

uhm,i think the problem might came from ur vcore, vdimm and the ram divider and timing..
mind to list all the things wrote above ? i mean ur vcore and bla bla..

btw its SuperPI 32M, not 32MB..

i think it was my ram... my friend also said that..
im using value ram only... can u suggest a good ram divider and timing
i wan try it

this is just a suggestion - 5-5-5-15 (1.8v ~ 2.0v) or 4-4-4-12 (2.0v ~ 2.2v)..
use either DDR667 or DDR533..
plz try to use CL5 first..

and then take time to read the existed thread for AM2..
u will find a lot of guide and information there..

it might be your ram limiting the oc. ur ram basically hit the wall already. try push the ram by either using loose timing or increase the vdimm a bit just like what kalakatu mentioned

*if u want cheap ram, i got a pair of Team Elite to let go

forgot to mention, if the same problem occurred, keep lowering the divider and loosing the timing..after DDR667, its DDR533 and DDR400..
for timing use only either CL5 or CL4, but i recommend u to use CL5 first as the timing is looser..

ehem i had i problem now...
dunno where to change the ram timing or the divider...
cannot find in my bios...
getting dizzy oledi...

there should be a way to unlock those setting..
but i forgot already..need to press some buttons to reveal it out..

Do unhide the hidden setting by pressing CTRL + F1 if not mistaken


-pWs-

lolz.... plz remember it back lol... really need to know...
also i need to know how to change the HTT link and NB link...

trying to google 1st..

Added on June 4, 2007, 6:24 pmhurm.. i still had the same problem eventhough i already change the ram timing... T_T..
sad lol...

can u post your cpu-z on your ram setting?? do you try to make it 1:1 (2.00) setting??

what is your vcore then??

why do u need a new thread?
use the ones that are ALREADY there
