| 269136 | 2004-09-04 04:11:00 | I've read most of the threads i could find on the two different cores, but im still baffled. Would a 3.0E Prescott outperform a 3.0 Northwood? My motherboard has 800FSB and dual channel DDR ram. | dirtbag (6060) | ||
| 269137 | 2004-09-04 04:20:00 | Most probably. I think Prescott get hotter too. | Spacemannz (808) | ||
| 269138 | 2004-09-04 04:26:00 | how certain is 'most probably' :) | dirtbag (6060) | ||
| 269139 | 2004-09-04 04:28:00 | A definite maybe. :O | Graham L (2) | ||
| 269140 | 2004-09-04 04:30:00 | thanks for clearing that up, prescott it is! | dirtbag (6060) | ||
| 269141 | 2004-09-14 00:23:00 | I run a Prescott 2 . 4a chip (No Hyperthreading, 533 FSB) 1mb L2 cache . . When you go over 3 . 5 Ghz then the northwoods fall behind in benchmarks a bit but upto 3 . 5 Ghz they keep up fairly well . I run an Abit AI7 motherboard, and 1GB good DDR400 ram . Just built this 2 weeks ago . On Stock cooling fan and HS my prescott runs at upto 3 . 240 Ghz (Overclocked) with the FSB at 180mhz (720 Mhz effectively) . This is totally stable for gaming and dvd encoding etc . It gets unstable at over 3 . 3 Ghz . My processor idles at 42 degrees to 48 degress and sits at 55-65 under load . I am looking into peltier watercooling and then will get try for over 4 Ghz out of this . They do upto 3 . 8 on big air cooling . The Prescott is the new chip for the future, and I built my system with the intention for upgrades to cooling etc in mind . As it is a HTPC, gaming and video rig, I don't care about hyperthreading in the least . It will backup and burn a DVD with DVD Shrink in 34 minutes . Not bad for ripping, encoding and then burning . That is with 4x DVD+R media too . I am really happy with it . My 2c |

| 269142 | 2004-09-14 00:26:00 | Arh not it wouldnt, were talking about socket 478 are we? What chipset does your motherboard use? | Pete O'Neil (250) | ||

Peltiers are a waste of money, they use to be alright but now days they have no place in the overclockers arsenal. Either go watercooling or spend the big money and make the jump to phase change. |

Prescott when used in a socket 478 motherboard is slower than northwood, theres no debate about it. The only time that Prescott out preforms northwood is when used with the latest ATI chipset. Dude get over peliters there a heap of ****, if you want to overclock you have 3 options, high end air cooling, water or phase change. Peltiers are grossly ineffective and are very costly. Also need to take into account that the preformance gain from peltiers over water is very minimal and the increased cost is large. Oh and another thing, because HardOCP saying a motherboard will do something doesnt many it will. My initial posts weren't intended for you, they were intended for Spacemannz. |
