Pentium D-915

hey, just wanted to tell, thats a great chip!! overclocker friendly and very cheap (88 bucks on the egg) I got it a 3.8 stable on air with stock voltage, but at 4.0 the software gets unstable (luckups etc), so I wonder, should I raise the voltage??
 
4.0GHz is always a nice target but before you raise any voltages, be sure to check your temperatures.
I had a 915 as well but my Foxconn motherboard limited my overclock to 3.36GHz (240x14).
 
yeah I know, I should be happy with 3.8, but nevertheless 4.0 its a a very nice target indeed, my temperatures are 50c idle, 75c on like 5 hours into orthos (with the stock fan and some ac5)
 
With those temps, I would be very hesitant to raise the voltage at all.

You might want to look into better cooling before you do more with this chip. If you're using a sub-par air cooler, look into a Tuniq Tower, Thermalright Ultra 120, Scythe Infinity, etc.

Yeah, definitely don't raise the voltage if you're using the stock cooler. To hit 4GHz you'll need better cooling than stock.


 
thanks for the replys guys, but a question, how far can the chip go before it starts throttling or gets some permanent damage? (by heat)
 
1) Turn off all the throttling stuff like CIE and EIST and all that jazz.
2) Get a Tuniq Tower 120.
3) Head for 4.2GHz (300x7).
4) Keep temps below 70C.
 
Man, pickup a used scythe 1000 for cheap on newegg and then you could definitely reach 4.0. There are other heatsinks that are better but I sense that you are on a budget.

what he said...but I don't like my temps over 65C
 
I have a strange/weird scenario for my PD 945 3.4GHz.

Using Asus P5N32-SLI Deluxe; first I run the processor and ram at stock specs:

PD 945 3.4GHZ 800FSB
RAM @ 533

Temp: idle 39-40C; while gaming @ 49C using Thermaltake Big-T.

Then I OC:

PD 945 @ 3.91GHz
RAM @ 460
This is to maintain 1:1 ratio (920FSB/460)

Temp: idle @ 35-36C; while gaming @44C.

My question is why do I see the reverse affect and not the other way around?

yeah thats true, iam on a budget😱, is the scythe 1000 better than a zalman?

That is hard to say. What program gave you those readings?

Are you sure those aren't vice versa?

I use Asus Probe for both instances.

It wasn't vice versa because I've been running PD 945 / RAM at stock speed for about 1-2 months. I just started OC about a week ago and notice the temp idle/load is +-5/6C lower in OC than was in stock. I even switch back and forth between stock and OC; the temp is reproducible.

I don't know what gives!
