Whats a good P4 i can OC and will WC b required.

More about : whats good 0ghz

July 10, 2006 1:16:27 AM

a good old 2.4b will take you to 3.6 or even more. About 775 socket...i don´t know. But 4Ghz it's a bit hard for a p4 to handle.

gee man, there are a lot of threads regarding the d 805. Search the forum for them.u can take them to 4ghz, but you have to buy wc and a great mobo.
July 10, 2006 2:11:46 AM

Plus it would waste a lot of electricity. It can be done but you have to get water cooling and a good motherborad as PMR also stated

P4 506. Cost: $85
July 10, 2006 12:12:01 PM

ya but thats just it i dont want water cooling and im not gonna over due the overclokcing, because i wanna try to get 4.0 without raising the volts much.

I had a celeron d, 2.4 going 3.6 on an asus p4s800 mobo. Probably could have got more if I tried. Ran stable as anything. Although mobo died, chip is now in this machine here, so it lasted many years. Only used stock cooling, and never got above32c, at idle.

I can tell you that a P4 3.0E is definately not a good one to overclock
mines a rev c0 and it will hardly reach 3.2 without crashing windows.

i just cant coo'l it fast enough, i've had it up to 72 deg c under load p95 (2 instances)

Moof:

I've got a P4 Northwood core stock at 3.2Ghz. I've got a zalman 70mm HSF with excellent case cooling (I think that's the key here, CASE COOLING). I've OC'd that baby to 3.9Ghz easy. I did some test to make sure all components were stable. I had el CheapO RAM in there before...some cheap Infineon RAM, 2GB of it..... can't OC past 3.5. I then bought 2GB of PC3200 Corsair XMS XL 2-2-2-5 RAM and BOOM!!! that baby flew past 3.5 and got to 3.9. All this was done stock v-core volt, stock DDR volt, no changes. A solid platform also helps. I've got an Abit IC7-MAX 3 w/ OTES.

I know my system is old compare to you young bucks out there. I don't have all the fancy stuff nor do I have the money to spend but most of all, I don't really need it because this system, though old, still whips most newer systems ass.....(tongue in cheek here)

So, my suggestion: Get a P4 NORTHWOOD core, prob the 2.4, 2.8 or 3.2 version. Solid platform, good case cooling and high-quality RAM. If you've got those things (and you don't have to get what I have, it's just that it has worked for me), you should have no problems raising CLOSE to 4.0Ghz. I've tried to push to 4.0Ghz, but I just can't seem to twest that one little whatever thing I need to tweak to get past this impass.

Hope this helps.

My two cents.

for P4 with 478pins, Northwood series' extreme frequency is about 3.6GHz

and Pressoct series' extreme frequency is about 4GHz

there are some exceptions for sure

about P4 for LGA775, 5XX and 6X0 series are both has a extreme frequency at 4GHz to 4.2GHz

the 6X1 series can always oc up to 4.5G or higher and has a better temperature controlling.

above all are all single core P4 series
July 18, 2006 4:47:53 PM

Best one is the D805. You dont need water cooling just get a zalman 9500 and youll get 3.8 ghz with ease

no they dont. your talking out ur arse.

also. why do you need it to hit 4ghz??? i ask because depending the type of work you will be doing will make a difference on the CPU buy. encoding and the like will be better on a dual core system but if your only going on FPS your not going to notice the difference between 1 or 2 cores. all games at the moment are coded to only use one core.

more mhz does not mean a better CPU. a more efficient one will work faster.
July 19, 2006 12:31:42 AM

i would have to disagree Overclokcing does efect the FPS. my friend has a AMD Athlon 3500+ 2.2Ghz Stock and we OCed it to 2.6 and his score on the 3DMark03 was 1000 more and we can OC it more but my friend didnt want to rais the Vcore. And if we rais the Vcore we could get to 3.0Ghz thats almost 1Ghz overclock it does make a difference.

July 20, 2006 3:58:36 AM

If you just want a p4 running 4ghz because its cool (which it sure as hell is), and dont really care about money, then deffinately go for the 670... it would be a snap to OC it 200 mhz higher

If budget is a factor, then buy the highest speed you can get... a 660 will be harder to oc to 4 then a 670, just as a 650 will be harder then a 660.

buy the best you can afford, and deffinately wat untill the 23 to buy... PRICE CUTS!!!

920 is a better grade CPU than the 805's everyone talks about, will overclock at lower voltage, consume less power at equal speeds, and have better memory access.
July 26, 2006 3:42:27 PM

Wait a month. The Celeron D 360 is coming out.

Before you start screaming "It's not a P4!", well, since people were mentioning old P4s and so on, it's functionally identical, thanks to its 512K cache.

Yes, you read right - that's essentially a re-badged 65nm process Northwood running at 3.46Ghz. $85. "Celeron" instead of "Pentium" on the cover. Overclock it all you want - it's crazy fast for little cost.

Features:
D0 stepping
Silly low power use.
Identical speed to the same Ghz in the older Northwood series.
Socket 775 - so upgrading later on isn't a big deal.
26x clock multiplier - silly overclocking potential.
Should overclock with an aftermarket air-cooler to 5.2Ghz.(200mhz fsb)

Note - it's not out yet, but the 356, at 3.33Ghz gets to 5Ghz easily. The 360 should easily match it.

You essentially get an older P4 to OC to 5.2Ghz. Even by the most recent dual-core standards, that's mighty fast.

http://www.xtremesystems.org/forums/showthread.php?t=10...
1/3 the way down - 5.08Ghz 356 running with a large aftermarket air cooler. 55C temp. 10,000 score in 3dmark2005. That's impressive. I don't care what it's named if it gets scores like that.

The 805D needs water cooling to reach this score - it just gets too hot. 55C is high, but not unreasonable.

I've been overclocking Celeron D's, they do go "fast" but are not on level with Northwoods, clock for clock. My 2.6C at 2.6GHz beats my Celeron D 310 (2.13GHz) at 3.2GHz. The Celeron D's are Prescotts with cache removed.
July 27, 2006 4:07:14 AM

Um - check that again.

THESE ARE ALL NEW CELERONS WITH 512K CACHE.

These are what Intel should have made all along. They are very fast for their cost, especially when you consider that dual-core is mostly wasted for the average user other than the 5% of the time it kicks in in a meaningful manner.
July 27, 2006 4:36:17 AM

I would say go with a D 930 and Thermaltake Big Typhoon to cool it. I've heard those will OC to 4.5 on water without too much effort. I think it'll hit 4 on air though
July 27, 2006 5:01:07 AM

Unless you can cough up a link to some benchmarks comparing a Northwood P4 to one of these new Celeron Ds, you don't have the right to continually make comparisons saying that they have equal performance clock for clock. Everyone knows that the Prescott P4 was slower than the Northwood P4 at the same clock speed (barring applications with SSE3 optimizations), due to the fact that Prescott had a longer pipeline and a higher latency L2 cache. A doubling of the L1 cache and L2 caches still didn't overcome these deficits on Prescott.

If anything, I would think that the new Celeron Ds are comparable to the Prescott P4, perhaps just a little bit behind it on a clock for clock comparison. It depends on where the "fine line" is on L2 cache size being just enough and too little. As we witnessed from the Northwood Celeron to Prescott Celeron, a doubling of the L1 and L2 cache had a MUCH bigger effect on performance (a 10% increase clock for clock) than the Northwood P4 to Prescott P4, where virtually no improvement, and actually some slight decreases in performance were noticed. That was due to the fact that 128 KB of L2 cache just isn't enough on the Netburst architecture to prevent pipeline stalling and flushing. The 256KB L2 on the Prescott Celeron seemed to be the Messiah, greatly increasing performance despite that fact that it still had the same slow latency L2 and increased pipeline length of its big brother P4. Still, comparisons of the Prescott P4 to the Prescott Celeron showed that the diminished L2 cache of the Celeron D still hampered its performance. The question now is whether the 512KB L2 cache will show similar gains in performance that were shown in the move from Celeron to Celeron D, and whether this gain in performance will bring the new 65 nm Celeron D up to the same level of performance as the 65 nm Pentium 4s (which, by the way, still use the same pipeline length and slow cache latency as the Prescott P4, explaining why we don't see any real improvement with the 65 nm P4 over the 90 nm P4 in terms of performance on a clock for clock comparison).

According to the Extreme Systems link you posted (which I gave to you), a 5.0 GHz 65nm Celeron D games as well as a 4.5 GHz P4, so there is obviously a noticeable performance hit going from 1MB L2 to 512KB L2, meaning that the new Celeron Ds SHOULD NOT EQUAL THE PERFORMANCE OF A NORTHWOOD P4 ON A CLOCK FOR CLOCK COMPARISON. Saying different is just ignorance. :?

Still, the new 65nm Celeron Ds are a great processor, without question the best single core Intel processor yet produced. If it can easily overclock to 5 GHz on air, on stock voltage, using the stock Intel hsf, staying under 50C, consuming less than 130 watts, and then go toe to toe with a 3 GHz Opteron and come out the winner, then it definately has my vote. :wink:

Unless you can cough up a link to some benchmarks comparing a Northwood P4 to one of these new Celeron Ds, you don't have the right to continually make comparisons saying that they have equal performance clock for clock.

It's not hard to find comparisons. The chip is within 1-2% as fast as the original P4(533mhz series). Some tests I've seen show it ahead, some a bit behind, but quibbling over .1Ghz isn't really meaningful. The thing is, the 360 overclocked will run like a Northwood in the ~5Ghz range, give or take, IF such a chip could be run that fast. I don't see many people OCing a 3.06 to 5Ghz, though I'm sure someone did it once or twice to see if it could be accomplished.

It's cheap, fast, and going to be great for games.

While it won't do what you listed, it will do 5.2Ghz with any aftermarket cooler, use about 150W, and temps will be at about 55C. Speed-wise, it appears as if it is comparable to a 3.8-4ghz 805. Just a lot less heat, normal cooling, and way less power as well. And that's with the clock set to 200mhz. The beauty of it is that the sepcs are JUST what the current boards can handle. You don't need a $180 4-phase board from ASUS and a super-fancy air cooler. It runs hot, but not unreasonably so.

That was the main problem with the 805, in fact - the thing ran hot enough to seriously stress the motherboard itself. 200W under full load is also crazy. If I can get 80 or even 90% of the results with 2/3-3/4 of the heat and power, sign me up.

BTW:
If the clock is jumped to 250mhz and you go for water-cooling, that's 6.5Ghz and a 3dMArk2005 score in the 12-13,000 range. I am figuring that 200mhz is the sweet spot, though - almost any board these days can handle that and the power/heat stays at reasonable levels.

Dude,

The Pentium 4 805 is perfect for OC'ing. Toms took the 2.66 Ghz 533Mhz processor all the way to 4.1 Ghz. That more than 50% OC'd. See the link here for thier article.

http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=1108460#1108460

On Newegg the 805 is going for $104, you can't beat that. I had it OC'd all the way to 3.6 Ghz with the stock Intel fan, and have it OC'd all the way to 4.0 Ghz with a water cooling rig. Who cares if it uses more power OC'd like that, my computer screams....

The 920 is better than the 805, you can get to 4GHz with less fuss and less power consumption, at higher bus speeds for improved performance.
July 27, 2006 8:46:46 PM

Yes, you might be able to come close with a Dual Core 920, but you have to pay a bit over $200 for that, $212 for a retail box. But the 805 is right around $100, on Newegg. I stand by my answer, take the $100 you save when you buy the 805 and save it for a Conroe in the future or a better graphics card now. Tom's was able to compete with the performance of the Pentium Extreme processors (costing around $1000) when they OC'd the 805 to 4.1 Ghz.

Also, if you run the 805 on a 975 chipset motherboard, and OC it to 4.0 GHZ you will be OC'ing the processor to 800MHZ. That only stresses the processor, because the MB itself is already set to run as high as 1066Mhz. If you keep the processor cool, you can buy a Conroe a year from now when they are cheaper and run it on the same MB, Memory and Graphics card.

The 920 might come close? The 920 overclocks higher than the 805. You're missing the point why the 805 was chosen: it was the cheapest, lowest clocked CPU. A 60% overclock sounds better than a 40% overclock, even if the 40% overclock yeilds the higher frequency.

The question as I recall was for the BEST processor to overclock, not the cheapest. The 920 assures a higher quality core.

My 2.8c becomes unstable at 3.3 and with 5:4 ram freq.
So, went back to 3.2 and 1:1 with ram at 460mhz. Never thought these Buffalo sticks would hang so good at these frequencies.

And never heard about a 2.8c that passed 3.6-3.7. Not impossible though... 8)
