I have overclocked my E6850 3.00 to 3.5 and am using a multiplyer of 9

anyway i thought that as people are gettin close to 4 Ghz i went stight for 3.6 GHz and after about 20 mins the system reset. when i restarted i thought it was a loss of power and then it ran for another 20mins and it crashed so i then put it back to 3.5 and its fine but i want to get more out of the processor. i know its not a temp issue as its water coold and at 45 under load and 20 something idle (as i always run prime95 its not often idle)

Anyway i dnt think its a lack voltage issue as i incresed it slightly but not sure so any advice would be well appreciated

Thanks

what ram do you have?

use speedfan in ym sig and post your voltages and temps

any other info neded?

if this is your cpu Core 56 then your limited by the temp of it

if you mean that my CPU can't go over 56 then thats wrong as with the stock fan the temp used to be at 65 regularly and also when i accidently puled out the water cooling power its was at 110 deggrees so i dnt believe that it is this!

up the voltage a bit

Only up it by 0.2v or 0.5v increments. As 0.1v has a ratio of about 2c-4c.
Also i have included an app, its designed for looking at Dual core Temps.
One thing you must watch out tho is the T-Junction temp (Bridge between the cores) If this exceeds the Max temp of that your CPU can handle then you need to back the OC off or get a better heatsink/fan.
You are required to activate the T-Junction temp in the app settings. Now dont freak out when when you see your CPU temps jump up.. I get somthing like this...

Tj. Max : 100c
Core #0: 61c to T-Junction max Remaining
Core #1: 63c to T-Junction max Remaining

What this is telling is in fact i have 29c until core #0 reaches max Tj temp which for me is 100c. Your CPU could differ.
*Note* If your CPU reaches Max Tj temp it will shut off. (This could be the source of your crashes)

I am usin the Asus booster and it only allows me to use a minium CPU voltage of 1.5v however the CPU voltage at present is 1.4V. should i just wack the voltage straight up to 1.5v or what?

1 g0t 0wn3d

V core (V) ? 0.85 - 1.5
Min/Max operating temperature (°C) ? 5 - 72
Min/Max power dissipation (W) ? 8 (Extended Halt mode) / 105.15
Thermal Design Power (W) ? 65


that will be your max voltage your chip can take

That is exactly my spec!

so what do i do with the booster as the temp automaticallly goto 1.4v shall i jack it to 1.5v or will this damage my CPU?

linderman

I would not run your cpu at 1.5 volts!


what is the model of your cpu ????


you need to manually adjust your overclock once you get around 3.4 ghz and higher >>>> booster programs dont cut it any more

you need to give us the exact model of your ram sticks and how many you have ?

you can use Cpu-z for this / then give us a screen shot of each tab within cpu-z

I'll bet your ram voltage needs to be increased and your ram ratio needs adjusting
