P4 1.7 OC W/ Standard cooling

[akiraxtc]

Would it be possible to overclock a P4 1.7 to anywhere above 1.8 or 1.9 with the standard Intel HSF?? Or do i need to have more aggresive cooling? I definitely won't go for more than air cooling... no water cooling stuff for me. One more thing... i bought Inwin IW-508 with 300W PSU and i will have 3 HDD and 2 Optical drives and almost full PCI Slot..would 300 W be sufficient?

Please don't crap the tread.. we had enough of those stuff.."P4 sucks!", "why'd you buy p4???". I hope this thread would be informational

Thanks All

dunno if it helps much, but a friend of mine got p4 1.4and his tops off at 1.7 with decent cooling. nothing he can do can get it to go above 1.7, dunno if it's his cpu or just the p4 core. then again, isn't the .18 p4 supposed to ramp to 2ghz?

I would just use motherboard monitor, and watch your temps, Heck, it seems that the P4's clock very well without a voltage adjustment, or perhaps a small 1 may be in order. My 1.5 gig did 1725@ 1.66volts, with the stock cooler, of course the 1.7 may be a different story, I would just try it, and watch your temps, if they don't get over 50c or so on the cpu under a load, you should be fine.

Using the Intel hs/fan and Arctic Silver, I got my P4 to 1900mhz. I tried 2000mhz, to no avail. But I didn't try 1955mhz until I got my Orb.

 

[akiraxtc]

Thanks guys for your inut looks like i'll try to get a higher wattage PSU with the new header. Do any of you know where to get one cheap?
I think i'm going to get an indigo orb and see how it goes

Check out this thread, regarding P4 and power supplies.

Personally, if I sunk the money into a P4,RDRAM, and a motherboard I don't think I'd be looking for a "Cheap power supply unit". Hel! buy the best one you can and keep that system running.

 

[jamesbond007]

Yeah, I went with an Enermax 350W. (EG365P-VE-FC) I will be having a farily loaded setup as well. Enermax makes very strong PSUs, so I'd personally go with them. They're a bit on the pricey side, but you will learn; you get what you pay for.

I've got a 1.7 on the retail heatsink with Arctic Silver II in a reasonably well cooled case and a P4T. It can do 2006Mhz stably but cannot do 2076 reliably. This is my current config:

Asus P4T bios 1004
P4 1.7 Retail at 2006Mhz
1GB of PC800 ECC Rambus (two 512mb rimms and 2 crimms) at 944mhz (472mhz), turbo enabled
Leadtek GF3
Win2k

One thing to keep in mind when overclocking is most PC800 RDRAM can only overclock to about 880-900mhz reliably. I had two Samsung sticks that could only do 880Mhz with solid stability. Luckily, these ones I have now rock.

Congrats man! Have you tried clocking down the ram to 3x? You should be able to hit 2ghz that way easy.

 

[Wingznut]

Yeah, but outside of making myself feel more like a man, what's the point?

 

[akiraxtc]

Thanks for all the inputs... i overclocked my P4 1.7 to 1.9 Ghz without a hitch, using standard intel HSF and its thermal paste. Haven't tried higher clocks. BY the way the memory settings is still set at 4x. Will post here later if i can reach higher speeds with standard cooling and same 4x memory clock

knock it down to 3x bud hit that 2ghz


Might want to invest in a little more cooling as well. My rig can hit 2.03 with the ram at 4x. It may just be a matter of cooling a little more.

 

[Wingznut]

Have you done any benchmarks with the RDRAM @ 3x? I'm guessing the loss there, would kill the benefits of upping the mhz, or more.

 

[akiraxtc]

So are you implying that if we bump down the ram to 3x we would have a loss in performance.. say like a long time ago when we disable the cache on those 300a celerons to get higher speeds?
I'm going to test for myself, 1700 @ 4x and 1900 @ 3x to see the difference in sandra membench

Sisoft really isn't a test because it only stresses one bridge of a chip.

3dmark 2001 is a real test that actually takes time to run and tasks your rig with complicated graphics.

It is true though I got a better score running at 2.03@4x on the ram then I did at 2.07@3x on 3dmark2001.

Memory bandwith does matter

OMG Texmaster just saw your rig pics... that is some serious air cooling.. 120 mms holy sweet mother of jesus what do you use to power those???

[plantboydude]

Those of you that have overclocked you P4s to 1800Mhz+ post some SiSoft Sandra benchmarks especially you Apex.
I'm an Athlon user, but I would just like to see how friggin fast a P4 2000Mhz is.
No cusses intended.
Cheers

Ditto.

I'm planning on migrating to a Dual channel DDR nForce, but the Northwood at 2+Ghz still sounds somewhat appealing.

RE: P4 PSU's.

I said (often enough by now, I would have thought). The ATX12V PSU &quot;requirement&quot; is more to get people used to the idea. Up to a P4 1.7 GHz will work pretty happily with a standard ATX PSU - it's the 2 GHz and above variants that will definately require the additional 12V supplied by the new PSU's.

Hope this sheds (again) some light on the matter .

lol thanks bud. Actually, before the P4 they all ran on a 300PS! (when I had a 933 PIII) Now they run on a 431PS because of the P4. Power hungry little bastard.

Actually, the sisoft benchies are not that impressive especailly the CPU benchmark. I dont like this benchmark particullay because it doesn't really task the cpu nor does it use all of the cpu's speed to test the chip, only one bridge of it. But, follow my pic link and I have some screenies up at 2.07.

I like the 3dmark 2001 more because it actually puts some strain on your system for over a minute
