Ok so I want to overclock my CPU

I've just installed a new CPU Heatsink
OCZ Vendetta
just like this one
http://www.newegg.com/Product/Produc...82E16835202008

My temps wre idling at 42C with my stock CPU
now they Idle at 34-35C with the new CPU Heatsink
and I used arctic silver 5 for my thermal compound so the temps may go down even more

I have a AMD 6000+ Windsor socket 125w dual core @ 3.ghz x 2

I was wondering if you could give me the know how to do this

I have already overclocked my GTX 260 by 20% so there's extra power being used there
and I have a Corsair 750w PSU
2 x2 (4 gigs total) gigs Patriot Ram at 5 5 5 15 timings

thought'd post a picture of my computer

Nice Rig Mac


I hate to rain on your parade but your Cpu is pretty much drained at stock speed .......your cpu came from the days when AMD was reeling from a body blow called Core 2D Intel ........... it tried to quell the storm by hitting the streets with a 3.0ghz dual core cpu but in order to do so they squeezed all the juice a 90nm cpu can deliver


if you want to play alittle >>>>>.(dont expect to see much performance gain )

you will need to set your cpu jumper free configuration to MANUAL to see these options

you can raise your CPU host frequency to 215 (its at 200 stock)

cpu multiplier = 15X

cpu voltage to 1.40 volts



then run orthos for atleast two hours ........ if your temps dont exceed 65C

then try 220 and test again ........... if you pass 225 .......... that will "milk" the cow for sure !


keep us posted ...............
Raise your memory voltage (Vdimm) to 1.85 volts or maybe 1.9 volts

Mcninjaguy

will do and I'll keep ya posted

I'll post my CPUZ and Coretemp after

Mcninjaguy

I raised my V core to 1.4 buts ishowing up as 1.28 or something
and I put my ram at 1.9v

I guess its fine but this has only been 10 minutes or 5 minutes after

looking good to me


if you look in your core temp screen shot ............. you will see your CPU VID is 1.35

you can crank up the voltages in the bios until you get close to that 1.35Volts in the cpu-z screenshot ......... where you see you are 1.28 volt now

I personally would leave a dabble of room ........... stop when cpu-z says you are at 1.30volts or 1.32 volts

as long as your stress temps dont exceed 65C .......... you will be fine ...........


knock em dead

linderman

your ram still has more room for added voltage ....... thats a plus as you look for the "end" of your overclock

Mcninjaguy

stress temps? using prime95?

and crank up the voltage to like 1.6 or something and the actual votage will be 1.32 or soemthing?

ok I'm gonna run Prime 95 later on today when I'm out or something but first some more fiddling with my bios

thanks for tip

I just started running Prime 95 and with the highest settings in prime 95 my old idle temps are my new full load temps

full load around 43C

gonna amp it up to 225mhz

linderman

dont use any more juice than needed on the cpu ............. 1.45 in the bios would be my personal max ........... some have gone to 1.5 but I am not a fan of that much

by the sounds of your expereinces thus far ............ 225 should be do-able

you may have to reduce your HTT multiplier to 4X (it usually defaults to 5X) when you go to 225

Mcninjaguy

will reducing the HTT (hyper transport thingy i guess) affect performance at all

I've changed it to 1.45
maybe something around 1.425 is better?

so in CPU-Z it reads 1.312v and 1.328v

I'll post back if any changes arise and with the test results of prime 95 when I go to sleep

I'm gonna leave it a 223mhz

linderman

HTT lower does not lower performance ............... it requires adjustment as the FSB changes to keep in harmony with all aspects of the system

Mcninjaguy

so leaving my CPU at 220mhz is probably the best bet?

linderman

I would try 225 at HTT 4X with volts at 1.40 and check it with prime 95 or orthos

Mcninjaguy

I changed the bios to V to 1.425 and it says 1.3 in CPU-Z on the dot

do you think 225 is the limit? can I get around 3.4 or 3.5ghz?

Mcninjaguy

got a random BSOD with these settings

1.425v
HTT @ 4x
225mhz
15x multiplier

so for now until

im leaving it on

1.425
HTT @ 5x
220mhz
15x multiplier

linderman

your call


but if you get itchy ............ I am confident 1.45 in the bios would finish the 225mhz

and bump the ram to 2.0 volts

Mcninjaguy

really so its the higher voltage eh

ok I think I've got the itch ohh man why do I lawys want everything to go as fast as possible?

linderman

you find a cure for that ............... save some for me, ok ?

Mcninjaguy

Done

Ram @ 2v

HT@ 4x
CPU 1.45v

linderman

looks good to me ............... I personally would call that "The End"


dont forget to "prove" it stable with a minimum of 2 hours in orthos or prime 95 for dual cores ................... verify temps dont exceed 65C during cpu stress

just booting into windows is a far cry from being "proven stable"


enjoy ....................


then let us know if you see any improvement while gaming ?
