Pentium D Overclock

[Deleted member 24505]

error,i only have 2x hard discs and 1x dvd/rw thats why i got the 430w.it is a high quality seasonic tho'.


slade,how are you cooling that chip??

 

[error_f0rce]

hey there error,

here are my rails-
+12-1=14A
+12-2=15A
-12=0.8a
+3.3=30A
+5=30A
+5 sb=2A

i dont know what else to try,what about chipset voltages,do they make any differance?

I believe that the only time you would use chipset voltages is if you are having a hard time stabilizing your FSB. I suppose that might become a problem when it at 300... perhaps slade could share what his chipset voltages were at?

Also I'm no pro, but I would wonder with only 14AMPS if that wasn't becoming a problem. I've read several places that if you stress a PSU to the max, often the rated AMPS/watt output on other rails will drop some, as it destablizes.... but like I said, I'm no pro. Anybody else out there do serious OCing with 14A or below?

EDIT: Also, your PSU efficiency will drop drastically if it starts heating up. From what I've read online, the manufacturer tests are run at unrealistic ambient temps, where our case temps would be much higher, therefore seriously reducing the efficiency and output to below the rated levels.

EDIT2: Read this about PSU's: http://www.pcpowercooling.com/technology/myths/
"...power supplies produce 33%-50% less power than their advertised ratings."

my supply is aparently 80% efficiant.it could be we could do to find out and what supply slade has.

I got a rare 930 C1. Got i to 4GHz on stock vcore no problem. 1066fsb is great. So is 1066Mhz Ram

I'll try to go higher later.

And heres my not stable post. But gives me a good idea at what water cooling would give.

 

[Deleted member 24505]

that is a very nice chip m8.and a nice easy oc.i have had my b1 to 4.3 but not on stock vcore.

could you post your specs m8 pleez.

thx.

 

[fenixviper]

Specs are in my sig

what PSU are you using?

 

[BIOHazard87]

On my D 920 B1 I can hit 4.2 @ 1.43v

Im getting my 930 here later today! Ill post back with results

 

[fenixviper]

what PSU are you using?

Right now i'm using a Ultra X-Connect 2. But I have to change it because it makes a buzzing noise under load. It is perfectly normal but I just can't stand it. I'll probably go for a OCZ, TT, Mushkin or a NZXT.

Alright, new topic: Northbridge Coolers

How many of you use them for your OC'd rig?

What is the best way you've found to monitor NB temps?

At what OC % do you suggest implimenting an NB cooler to help preserve your chipset?
(from what I've read you don't really gain performance from cooling an NB, as you would cooling a CPU/GPU)

What are acceptable temps for the NB in your experience?

Well mine has a built on passive one, i touch it and it never gets hot, so

EDIT: btw my 930 fails,

max stable: 3.91 @ 1.41v... so sad

That's really not bad at all, considering average max OC on a 930 out of box is 4.125GHz. I'd be very happy if I could hit 3.91 stable... but must have new mobo to make that possible for me

Yeah, mine has a passive as well, but never feels too hot either. I just saw some reviews for a nice NB cooler, then thought "maybe you don't even need one." So I wanted to see who actually uses them.

It's freakin sweet that newer boards for Pentium D's/Conroe/775 etc OCing are coming stock with what looks like NB and SB active cooling!!!

Nice, how did you decide to mount it, or was it stock like that?

Here's a pic
Intel D930 @ 4.8 Stable

..............picture...................drool.................that has to be one of the cleanest, neatest looking rigs I have ever seen

Your 4.8 OC ​

Now that I've pulled myself together, question: what did you use to mount the Zalman (80mm?) over the NB HS?

P.S. what is the second SATA cable going to? (or is it just for symmetry?)

The Zalman fan is attached to the video card using Velcro The second SATA is my Plextor DVD-Burner

 

[pt]

mine is all passive cooled, it runs pretty hot under load (55ºc), it's the stock cooler, when i get a case with a fan on the side it will probabily lower a bit

 

[Casheti]

WOOOOOOOOW!! Nice 'n' neat rig. Mine is a mess, and it's only stock. But then again, not much room in Micro-ATX cases, eh?? lol

 

[Deleted member 24505]

the highest mine got too was 4392mhz at 290 fsb.i think ita the asus p5wd2 (not premium) board tho'.that was at 1.425 vcore.

mine isnt too bad inside-

 

[Casheti]

That's pretty neat, tig. Shame you can't conceal all the cables.

Heres an updated picture with the A/C Silencer 5 Rev.2

Man, tigger, we have very similar looking rigs, both with Pentium D 930's, AC Freezer 7 Pro's, x800 GTO w/ Zalman vf900 VGA coolers. You should list the badboy Zalman in your specs, that's my favorite component!

EDIT: I will post a pic of mine when I get home tonight, mine and tigger's look a lot the same.

my 940 goes well, it is just a B1, but is working fine.. i miss EIST

3,2 @ 3200 stable (1,16V)
3,2 @ 4000 stable (1,25V)

i'm using a P5WD2 without mods
well my watercooling has 52 degres water when i put 1,55V on core, cpu 77 degres an throtteling... i need dry ice
