The Official OC (OverClocking) Thread!

Potentially, it depends what your RAM's typically rated at. If it's 2.1V or above then you're fine. I think yours is.

 

What model and chipset do you have? Paste us a template of the OC settings "Extreme Tweaker Settings". Most ASUS OC nicely, but a few oC better yhen others. So far, sounds like s939, so nF4-SLI would be the good chipset to have, unlucky would be the limited VIA's.

@ cincyrob, What mobo & chpset? The E8400 is a shoe in for 400FSB on even Auto vcore, and that should be right around 1.32 @ 400. But it is also good to 500FSB easy on the right mobo and added vcore. 3.6 - 3.8 will need at least 1.37 - 1.41v loaded (vdroop). Read the voltage under load, this is the volts to aim for since most mobos have a .02 vdroop and some. Some Gigabyte have up to .06v drop under load. If not on a P35/X38, you will need more NB/SB & MCH and or PCI-E volts to help the FSB. And if given any kind of PLL, GTL Ref, or especially FSBT, up a little there too. Or if on a 965/975 and able to strap CPU to NB, try the 266 strapping. it helped my 1333fsb CPU on a !975X. Then of corse as you were adjust the RAM as needed. Even the low end DDR2 533/667 today can hit 800MHz with vdimm up, so you should be fine Beter RAM, more options.

Good luck

 

@Nuck
i have the gigabyte mobo GA-P35-DS3R, E8400 cpu, Crucial ballistic ddr2 1066 (pc2-8500)

right now i got orthos running with those newest increases i just posted. the vcore right now under load is 1.28-1.30 bounces back and forth.
ddr is at 2.21v
+3.3v is at 3.36v
+5v is at 4.92v
+12v is at 12.03v
vbat is at 3.17v

the core temp on both cores is at 64c. havent seen them that high yet. but i guess with the increases i did has to play in on that.
i have my new antec tricool 3 speed fan right above the CPU. i have it on medium speed gonna turn it up to high and see if that helps with the temp some.

 

Hey Cincyrob, Here is a guide for the 8400 to overclock it. Hope this helps.

Cool, great RAM, and yes, this mobo will handle the 500FSB just fine. You won;t get any GTL/PLL/FSBT to tweak, so you only have the PCI-e MCH, and DRAM to up. Take all but the .2+ RAM is good to the +4, but only if you use tight timings or high spd. I'd stick to 1:1 for now to get your CPU stable and you will run out of CPU before RAM easily. you have several options, 500x8 is a snap, but limited by cooling and needed more vcore, 500x7 is easy at only 1.36v as 3.5GHz and 1:1 for DDR1000 @ 4-4-4-12 2.22v. I like the 480x8 for 3.8 at only 1.47v. But this is RAM limited in 1:1 to DDR961. However, once the ig is stable, try the 5:6 divider (I'll test tonight to see if it's stable), and you get a nice DDR1153 at same 2.24v but 5-5-5-18 (or 5-5-5-15 @ 2.22v).

I used to hold 500x8 and DDR1200, but I found very comparable performance at the 480x8 5:6 DDR1153. This CPU overclocks like an E6750 so you can expect simular results as us using them + some. Some can 4.2GHz (water cooled is best for that). But on air, I'd strongly suggest a ThermalRight Ultra 120 eXtreme (w/ your existing 120mm fan) This for sure will keep even a 4GHz OC under 67c loaded. Most other popular models can work if you dont mind 72c +.

 

turning the fan up to high help'd temps down to 60-61c

thats a good link thanks

 

No problem i have that chip myself but dont have all the part for build yet

 

alright i need an alternative for temp monitoring

i use "Core Temp" to watch over my amd's and intel core,
now i just found out that it doesn't support Pentium 4 (p4)
i'll be monitoring a Prescott and we all know how hot they get

any suggestions for a reliable monitoring software that'll be compatible
with "core temp"

btw: does any other older version of core temp work with p4??

 

Try speedfan.

New sig!

 

The Prescott didn't get all too hot (as such bloated about) and OC'd great on the right mobo and good air and better on liquid. They may climb to 70c but can actually handle 80c. I went through just about all the Prescotts since s478 to 660 and I never had an excessive overheat, and they were all 4GHz OC's on air.
What model and mobo will you be workin' with? Non OC'd units with EIST cooled to as low as and below 31c. My P4 3.4E (s478) as 290x14 to 4GHz idled around 38c and only loaded to bout 66c.

I persinally cant remember any of the old and or new utilitys even from Intel to read the core temp of any of the Prescotts or Pressler. All I remember is the die temp and this is just essentially the IHS temp. Everest will display the CPU die temp on chip.

 

I personally think the Athlon XPs got just as hot as the Prescotts, but I haven't seen any CPU get that hot since unless it's big time overclocked.

 

Try PCWizard. linky to utility...

...gm

 

Oh yes, for sure, I can agree. Back when I used to game @ LAN partys, I've seen several Bartons overheat and heast up a small livingroom to trip off TM on an Intel Northwood. I had a lightly frosted pop can defrost in seconds on top (of the aluminum case) of my Barton 2500 to 2.6GHz.

 

Haha, yeah, it was a hottie, fortunately the first PC I took to LANs was my 4200+.

 

thanks for the software suggestion
garmoon, although it doesn't read my temp its a a great app that'll be very helpful to me!

oh no just to keep the poor thing at 44C (idle process) im running a fan that was meant for a 3.4ghz cpu!!! its a pent4 2.8ghs 1mb l2 cache Prescott

compare the Prescott to Northword and the difference is unbelievable, if you can find a rare cedermills core then you'll now the meaning of "A silent pc"

im just glade the "p4" era is over, im very happy to be a duo core user!!

-thanks to all here for the software referrals
-tripplite

 

No offense, just wanted to clear this up.

It's Dual core, not duo core. Unless you were trying to say Core 2 Duo, then the core comes first

 

Yeah, be specific. Pentium Ds weren't exactly great in the heat department...

 

sammorris,

They weren't exactly great in the performance Dept either! LOL!! It's no match for the lowly 3800x2, overclocked or not!

Speaking of my D-940! It died! It ran this morning and this afternoon I get fan, lights and a solid HD light. No post or beeps, but it does nothing! NB is warm but the CPU is cold as ice. I've tried different memory and tested what was in it and that's all OK. I tried a different PS, and a different video card and that's all OK too! I'm open to any suggestions short of Dynamite! LOL!!

Russ

 

Russ I saw some cheapies on TD I think. lol. You might check there and see what you get for an "older" Intel cpu. My only suggestion.

.....gm

 

Maybe not , bat certainly cooler then my early A64 x2's. I was able to Prime my old D-950 (C1) to 4.59GHz as 270x17 @ 1.41v (1.32v vdroop) on air to only 59c primed and idles to low as 42c w/ ThermalRight Ultra 120 eXtreme of corse. Frequent OC for xvid work was 267x17 @ !;@ DDR1067 (several Cs' cooler in idle or load working at 1.272v loaded)

And a P4 2.8E to 44c idle, wow. I had even my P4 3.4E on the 14x to same 2.8 w/ 1.35v and idled to 32c.

This same D-950 (C1) is a daily OC to a gentle 4.25GHz on air and only idles to 38c and barely 53c loaded. It's still in AU"TO vcore for 1.12-1.25v. But just for the record, I had 2 and the 2nd was retired to same OC but on Zalman CNPS9500 and it still did fine, just a bit warmer on both ends.

So ja, they get hot w/ cheap cooling but good air and water did them justice.
