How do I overclock a Pentium D?

[beyond_amusia]

As you can tell from my specs I have a Pentium D 925, which is just a crippled 930... I'd like to overclock it. My BIOS has all the needed settings to do it, but I've never overclocked a 'modern' CPU, so I don't have the first clue what settings to change. a quick Google search didn't reveal anything obvious except one review that claimed to get the 930 overclocked to 4.125GHz with the stock cooler, but they used a differnt brand of motherboard than mine. I do have an aftermarket cooler installed and idle at 46C (one hot chip, lol). So... What do I do first?

With no multiplier adjustments available it was simply a matter bumping up the bus and adjusting the memory ratio for my P4D overclock.

What kinda temps do you get with that?

 

[hat]

I am interested as well... 1.360 is the same as is read in CPU-z for mine at stock.

Heres mine..... just crank up the fsb and the vcore

I used the Asus Overclock Profile and chose to "Overclock 30%" and got this...

But BIOS is now saying my RAM is PC2 3200...

 

[beyond_amusia]

Okay... When I go into BIOS's overclocking area if I choose to overclock manually, I and presented with a field that allows me to choose the frequancey.... from 200 to 450 I think. Why can't they just say x.xxGHz...?

+1. The Jizzler knows the deal! Bump the bus, watch your temps. That simple. What kinda oc'ing have you attempted with your ram? (If any) Not a necessity, but if you can it will help out..................

the bottom one. I set it to around 260 and got 3.9GHz, but at 4GHz, so as Windows tried to load it shuts off for a couple seconds and then powers back on...
Actually, if I overclock even just a little bit, when i save the settings made in BOIS or Restart from Windows, the tower completely shuts off for a couple seconds and then powers back on; that's not normal, so should it worry me?

Well, if I choose to overclock via the Overclock profile, it underclocks my RAM... BIOS will say it's PC2 3200 but CPUZ says overwise.... atm, the RAM is still set within the PC2 5300 range... Anything above that and Windows will not start.

^^ Asus Mb will do that some times with the bios reload [more ofton than not it shows it's ??? it self as to post or give you the 'F1' option

So Asus should exit the mobo arena and just make over priced shity laptops?

 

[Frogger]

no it's just it "really don't like" the setting you set but it will post any way but not stable ...

Dude, don't use oc profiles. Oc manually, for stability reasons. Start by reading Kursah's OC guide here on TPU, because it's a great guide, seriously! Kurash knows his stuff....(respect)

ty.

I honestly don't know why Asus won't release a BIOS update to support core 2 Duos and Quads... The board supports upto a 1333MHz FSB (but only PC2 6400 RAM), so it's perfectly capable or running the Core 2s with a new BIOS... *sigh*

P4, X700 and RAM OVERCLOCK

lolz!

LMFAO! So true!

I'm going to try to make this bitch hit 4GHz... =D *slaps Intel for not having Hyper-Threading on the regular Pentium D and then kicks them them releasing chips that run hot enough to heat an Antartic orphanage* Asus, you guys are bastards too! lol.

About 58-59 under load.

Using a Scythe Ninja in a Lian-Li A17 (I need to update my system specs).

The P4D is decently lapped, though I didn't do that good on the Ninja. Dropped 2 degrees overall.

Good goal. At 266 FSB, you should be able to get the memory at 333Mhz.

On my board it would be like this:

-img gone-

4Ghz with your 15x mult chip.

If not stable, probably have to bump up the voltage a bit.

 

[beyond_amusia]

I tried 4GHz and Windows would not even start up. I had the memory timing set to Auto and Bios decided I had PC2 4800, so I lower the CPU freq. to 250 and I am sitting at 3.75GHz... I'll keep trying. The voltages are all set to auto; I'm scared of changing them and having my CPU or RAM get fried.
