Aircooled Prescott 2.8@3.91 on Max 3

[chainbolt]

Max 3
Prescott 2.8E@3.91
Aircooled with Max3
Radeon 9800XT
4 x WD740 in RAID 0
2 x 512 MB ADATA DDR 500

Prescott is very well responding to additional voltage, very nice scaling. This is a good start, if the first production processors are already so good and easy to oc, it can only become better.

How are temps?

 

[JackBurton]

Not bad at all man! Very nice. And yes, what are your temps?

 

[cowdog]

One of chainbolt's links shows a screen shot of Windbond Hardware Doctor. According to that CPU temp is 50.5 C.

I'm not familiar with the Intel boards, but are the Abit boards known for showing a higher cpu temp than other boards (which is accuracte is a whole different story...)?

edit: of course, is that load or idle?

 

[Soulkeeper]

not bad at all

 

[MegaWorks]

excellent results, lucky bastard lol! Anyway can you give us some benchmarks?
One more thing what kind of cooling are you using?

got to be idle- PWM temp is on the low side. My PWM temps hit 35- 40C loaded.

linked for the

Now, benchmarks or ban!

 

[hytek369]

what hsf?

 

[THUGSROOK]

50.5*C idle is high, even for a IC7.

nice OC :beer:

tell me about it
that's the temps i get under load with my northwood configured below

 

[mamisano]

I am guessing that this is not in a case? The system temps seem a bit on the low side at 21c (70f).

 

[JustStarting]

My system temps are 20- 22C. It's not uncommon with good ventilation.

It's near impossible where I'm at in florida most the year seeing as the ambient temp is either 24c *air* or 21c *heat* thanks to central air&heat I could get it that cool by opening the windows when it rarely dips below 10c here but my blood's too thin for that because I grew up in the :sun: state

Right, but you have a "Hurricane" and also H20 cooling which limits the amount of heat dumped into the case. BTW, what is your room temp when your system is 20-22C?

 

[JustStarting]

I'm in a raised ranch, and my rigs are in the finished basement of the house. heat (NY winters) is set to 65F- 68F, so yes 20- 22C case IS realistic for me (and many other northerers this time of year). Summer temps MAY hit 24C case temps topps.

edit: four 120mm fans dumping into the case don't hurt.

 

[mato7742]

damn, i didn't realize prescott's could take so much damage. maybe this core isn't a fluke after all.

 

[JeremiahTheGreat]

Hm... I would make that statement after a few months...

Like the P4s/XPs before it, we don't know how it takes the voltage for a couple months! Last thing we want is for Prescotts to be frying like flies on a bug zapper.

 

[mamisano]

Chainbolt, what's the status??

 

[beyoku]

probably dead

"Sizzling hot is how we?d described that, as normally a processor temperature of over 60 degrees Celsius isn?t something we?d recommend. We then proceeded to see how the Prescott fared with a little overclocking and we quickly found out that at a mere 5% overclock the temperature would soon be touching upon 70 degrees Celsius, too hot to our liking. Fitting a different cooler, in this case an Akasa King Copper, which basically is a massive, fine finned, copper heatsink, didn?t really improve things much. The resulting temperatures, with the selectable fan speed at maximum, were about 5 degrees lower. Nevertheless we managed to clock it to a maximum of 3.75GHz at default core voltage and temperatures approaching 70 degrees Celsius. It could go a little further, with a bump in core voltage by 0.1-volts we managed to touch 3.8GHz, but quickly shut the system down as the temperature was at 171 degrees Fahrenheit, or 77 degrees Celsius in a matter of minutes. That, by our judgment, is nearing supernova temperatures and doesn?t show much headroom for current Prescott processors."
