Fun with 805D

[Absolute_0]

So one of my roommates needed a new computer and i suggested a few parts for him. We ended up with

ASUS P5WD2
Pentium D 805
500w Rosewill PSU
my old X850XTPE Graphics card
1gb G.Skill DDR2

He assembled it yesterday and we got to clockin. Cooling is on a Scythe Ninja that i lapped.

Got to 3.8 GHz with stock volts but needed a minor voltage boost to get prime stable



With more volts it'll go past 3.9 and benches past 4 Ghz, haven't tried more than 1.45v yet, these things get toasty.

But it's good to know that a 129$ dual core can do 3.8 Ghz on aircooling with nearly stock volts.

That is a warm little bugger. Nice job. You just cant beet that CPU for the price.

[EnJoY]

Nearly 4GHz on two cores for that price sure is a damn good deal. Nice results, you plan on freezing it real quick before it goes 24/7?

[Tasselhof]

What rpm/cfm was on fan(that used on SCJN-1000) ?

[PL4YD34D]

is that 60c with the scythe, that is hot hot hot !!!!!!!!

[Supertim0r]

no throttle ?

Yeah, time to put your phase changer to good use!

[Absolute_0]

LOL, hard to use my phase change when it's built into my Lian Li V-2000 case and the 805-D is in my roommate's newly built computer

Anyway, the poor guy has been on a 2.53 Ghz Dell with < 1gb ram and a GF4 Ti4200 for years now. With the 805D he could afford the leap to dual core, 3.8 Ghz dual core isn't too bad coming from 2.53!

The fan on the scythe was bundled with the heatsink, 120x25mm fairly low speed i think. I'm sure it would be cooler if the fan were more powerful. I did use Arctic Ceramique so i'm giving it a few days to set, i expect ~2.5c from that alone.

[greenwar]

good job hooking up your roomie with some good stuff.

[Absolute_0]

got the side of the case off and a fan blowing in



We will get at least 4 Ghz done tonight
Will update with prime soon

More comin'

oh god, i want one of these things to play with... get it cheap, wait a bit on conroe, but have the rest of the system setup for when i get that...

so tempting...

[Squid_Spit]

Nice, if i could just sell my spare S754 rig i'd get one of these in an instant.

Lap the IHS and the temps will go down. You will be able to hit 4200Mhz.

Man 4200 Mhz prime stable on air is pretty hard to do lol! THG needed watercooling and 1.67v to do 4.1 Ghz.

Which we're about to hit on air with 1.5v...

[Absolute_0]

This took a slightly chilly room

[stingush]

Very Nice MATE! GJ! tell me.. can you check the cpu with stock cooling and see if it stable @ 3.32GHZ with normal temps? it will really get me know the cpu better.. because i wanna buy one and :P i dont have much money spending on cooling

Forgot THG!

You have a real nice chip there and with a little bit more voltage and better cooling 4200Mhz is possible. I have seen this chip on air at that speed. In our country this CPU is best buy and a lot of people got it, because it's cheap.

If you lap the IHS you'll see a lot better temps ... 4100@ 1,4 volts right now is 61c. I think that you will be able to run around 50 at least after good lapping.

Got one here on stock cooling @ 3.4Ghz, runs @ ~ 56c with 2 folding clients running on there Although I did clean the standard intel TIM off and put some AS5 on there, its been up less than a week so I'd expect to cool down a little bit more as time goes by. Great result @ 1.4v Absolute_0, I'll push mine once I get some good cooling on there.

[stingush]

nice.. but you aren't in israel.. we got now 25-30C outside here

[irev210]

i plan to play with an 805 when i can get my hands on a conroe board, then upgrade to conroe.

[jimwah]

nice.. but you aren't in israel.. we got now 25-30C outside here

It doesn't rain all the time here check it out: http://www.bbc.co.uk/weather/5day.shtml?world=0008
24c today! Plus my 805's in a room with 5 other machines which fold 24/7 so its hardly cool in there.

I really don't think lapping the IHS is going to give 10c, i've lapped IHSs before and it doesn't do that much. What we need is some watercooling.

The voltage has some pretty bad vdroop. For 4.1 Ghz we set 1.50v and it droops down to 1.4v under load. We are contemplating doing the Vdroop mod but we need a VR iirc.

[[XC]Atomicpineapple]

Its given me at least 10 degrees lapping the IHS on my 805, as it came from intel it was utter rubbish, full load temps of 60 degrees on high end water!

[Absolute_0]

really hmmmm you are starting to tempt me.

I'll run it by my roommate, if we actually get it down 10c and he does the Vdroop mod, then we'll have a ton of headroom

*after doing some research you guys are right. I thought Intel IHSs were better than this but apparently not.
