Northwood P4 1.8A from Newegg experience?

Any recent purchases from Newegg with P4-1.8A? Was it from Malay or Costa Rica? How high did it go, 2.4G easy?
 
Got mine last week....It is a Malay

I am running 2.4ghz @ 1.57v delivered...MSI board is crap...I have it set to highest 1.65v but this is all it will deliver.
prime95 stressed...

Running stock retail heatsink at time being...44c right now...got avc sunflower with as3 coming.

I am getting asus p4s333 board and plan on taking it up to 2.5ghz...2.5 will post on board now but prime 95 will kick out almost immediately which makes me think of voltage, especially since ram is locked, temps don't have time to build up, etc...
 
I also got my 1.8A from newegg, malay chip. I have yet to see a 1.8 costa rica. Everyone seems to be getting Costa Rica 1.6A's, my only guess is Intel shipped a large batch of 1.6 costa rica chips recently, because it's a very hot chip, they could be in short supply and they are using the costa rica factory to churn more out.
 
well, i just installed my 1.8a northwood which is a Malaysia chip, and unfortunately, all i can get up to is 2340 using a 130 fsb, at 1.65v.

i really wanted to get it up to 2400 as well. at 1.70 volts, the Asus P4B266-C motherboard gives a hardware warning, and when i continue, it's a no-go.

any ideas on getting this chip up there, or should i just accept it as it is for this retail unit?

tia 🙂
 
hey rosco6912, at least u can boot up with 2400, hehe. btw, what voltage are you using to get booted? give us some more info of your setup and some of its quirks.
 
sorry for long resopnse time:

lets see... i believe 6.5v is about right i have 2x256 pc2100 ddr's from crucial... i can clock them to 174 and boot fine... just crashes when i do anything 3d oriented...
[ 3:4 132fsb ]
 
the PSU that i am using is the one that comes with the Enlight 7237 case, so it's an Enlight 300 watt power supply.

also, regarding the memory, i swapped it out and replaced it with Crucial 256mb stick, however it isn't letting me getting any higher than 125, cas2-2-2, so from my testing, i can see that my chip does NOT want to go higher.

one question for you guys though:

why are my memory scores running at 1800 faster than when i run at 2012 (112) or 2234 (124), even though in the BIOS, i set the cpu:ram ratio to 1:1 ? Is the bios kicking it back to 3:4 on its own?

lmk... thx

I hear that malay chips are better OCers. Does this hold any water?

Thugsrook, I am a bit weiry of extreme voltages, so I wouldn't push it too high. It accelerates electromigration, which in turn shortens the life of the processor.

Another thing, the PSU could be the problem for those who can't get stable 2.4.

I believe that on certain MBs, it automatically reduces the clock speed once the fsb reachest 124, so many people leave it at 123. I am not 100% sure on the numbers, it is either 133, or 124.

is that so? anyone else know more info about that?
 
my sl63x 1.8a malay from newegg will boot w/ 133 1:1 - but i can't keep it stable =/

i have an enermax 430psu and my ddram is 133 spec so i know its the chip. also i need @ lesast 1.66 to boot 2.4 -> should i use the o/c voltage jumper on my board? my dip switch (instead of bios)? p4b266c

thanks
 
tell me, do people seem to have better o/c'ing results when they use the jumpers on the P4B266-c mobo as compared to using the SoftBIOS options? as i read more, seems that the more stable systems are using the jumpers/dipswitches.
 
x86, Why do you think thugsrock 1.625v is extreme....amny at most sites agree over 1.65v should be when you worry....he is well within range...
 


<< Thugsrook, I am a bit weiry of extreme voltages, so I wouldn't push it too high. >>


yep, thats why im more then happy at 2.4g 1.625v 4:5 DDR 166/333mhz 🙂
