Presler 940 OC and normal temp?

post #1 of 8
Thread Starter 
I am getting a 940 presler * shipped already will arrive on tuesday* and the ASUS P5WD2-E motherboard and the ZALMAN CNPS9500 fan. I was wondering what the presler default temps are and how much oc can i get from that presler?

Not to sure about the Overclocking, but Ive heard good things about the Preslers, I know the 8xx Smithfields are awsome overclockers, and the Presler having the 65nm should be even better, plus it should run cooler (so Ive heard)
I do know that it will run warmer then your older CPU (there is 2 actual cores in the 9xx CPU) But Im sure you could get it a long ways when it comes to overclocking. My PD 820 has already passed a 1ghz overclock on air and it is a space heater.

Even with the shift down to the 65nm process the temperatures still remain high. Sometimes even higher than the 800 series. Having two cores does not help with the amount of temperature that is given out.

As there is a larger amount of cache on the 900 series it is natural for the temperature to be higher, the 65nm technology does help to compensate a bit but on some occasions the temperature will actually be higher. I would make sure that this CPU stays below about 70C though for best results and to make sure there are no problems with the CPU.

The board and fan are good, expect good results with that combination

well i want to buy a presler also... but... i dont know what model to pick...
the 930 looks nice and cheap but i want to oc it to a 5GHz clock speed min!
im thinking of using phase change so it will be easy to oc but can i realy get to 5GHz +? i will buy the Asus P5WD2-E Premium...
will the 940 or the 950 oc alot more than the 930?

What's wrong with your FX-55?

For sky-high overclocking.....Preslers. I know for starters it can do 250fsb with the default-multi and stock volts with the stock heat-sink/fan but who is going to use the "stock hsf?", so the Zalman should be better.

As far as temperature being a factor? I haven't seen that too much rolling around, as much as Smithfields that is.

Althought I'm still not convinced that a P5WD2-E Premium is necessary, specially that for what it seems the current 975X boards will not support Conroe and the difference between 955X and 975X is so miniscule but yet, price wise, cost is greater for the 975X......IMO it's not worth it.

Omri, if you want 5ghz out of a Presler chances are a lot better with a 950, but a 960 will certainly be much better, I'm waiting till October of this year, by then Q3 prices for the 960 would have settled and they'll be in the $316 price range, as stated by Intel. In the meantime if you have lots of $$$ the 950 will take it to (300x17) 5.0ghz with phase.

The ASUS P5WD2 is in my opinion the best board for the job.
Phase change is a very good idea to hit 5GHz with, but make sure that the rest of the components are up to the challenge, i.e. PSU, memory etc as without them that target is too high.

Now as for the CPU, it depends what you want. You can either save money and get a higher bus speed or spend more and get a higher clock speed. Even though the higher end 900 series do have the ability to switch between their default multiplier and a x14 multiplier.

These new CPU's do have a very good overclocking potential though, mainly due to their 65nm technology and their long pipeline. The longer pipeline does lower performance but allows higher clock speeds via overclocking.

I would, looking at overclocking potential and price, say the 940 would be your best bet
