28b stock voltages

post #1 of 9
Thread Starter 
i have a 28B e6600 at stock speed and voltage, and i was wondering how high an overclock do you think i could get with a zalman 9700 (tuniq wouldn't fit in my case ). PCprobe says its vcore is at 1.21v and idles at 30C on stock (Zalman is a christmas present). My mobo is at 32C. Do you think i could get it up to 3.8? If so, what voltages should i use?

It's 90 degrees in your house? (32 C ~ 90 F)

are you sure thats not your mobo temp or your case ambient, if it is you need some better airflow in that case

edit: yeah get some better air flow in that case then go to town and see what ya can do

PCprobe says it is the mobo temp, but since i have a 140mm ~68cfm intake and a 250mm 169cfm intake, the air is really moving, so i don't think i need better airflow.

i really don't think it is an airflow problem, that is the reason why i purchased the Aerocool Extreme Engine 3T.

50c with dual instances of prime95. I'm not quite sure if i have the stock heat sink mounted correctly, but it never goes over 50, so i figured i'd leave it until i got the zalman.

The Zalmans are not great heatsinks.....the 9700 is the same poor design as the 9500, just slightly larger. A minor face lift that doesn't help temps very much.

As I said in your other thread, be sure to take Vcore off AUTO, otherwise it will continually increase Vcore as you overclock when it is not needed.

For 24/7 operation, I would try to keep the CPU at 50c or so, defiantly not to exceed 55c which is the recommended maximum for an overclocked Core 2 Duo. Looking into a better heatsink would be highly recommended. The best heatsinks are block style with a changeable 120mm fan.....you want a lot of surface area and you want ALL of the surface area to have air forced over it in a single direction. the Zalmans just "swirl" the air around the fins, with the direct airflow of the open fan going over only the smallest surface area.
