Anyone got the P4 1.8a GHZ northwood yet?

[THUGSROOK]

duh - heres some results...

1.8a @ 2250mhz / 125fsb / 166memory DDR / default voltage / gf3ti500

3DMark2000: 12438
3DMark2001: 8550

SciSoft Sandra 2002:

check my rig link for more specs.
more to come.....

Reinstalling windows right now. It did not like being taken from a KT266A to an Intel 845 board, talk about a blue screen. Currently running at 1.8 and will oc when I get windows reinstalled.

I have a question about the 8irxp though if anyone has any info. I am trying to put a DVD drive and a CD burner on the Promise RAID controller and just use it as a IDE controller and not a RAID device. The Promise controller doesn't see them and I was wondering if like my old A7V266-E if there was a setting somewhere to tell it to be a IDE controller vs a RAID controller.

wierdest thing about this promise controller. If I hit ctrl-f to get into the setup on the boot I have a few options available. It deosn't matter what I select, the second I hit a key......reboot.

ok. finally got windows reinstalled, all device drivers up to date.

the bad news is i can't get the promise portion to get out of raid mode and just be a controller.
the good news is that on the first attempt at oc'in this northwood and I am running 1.8a @ 2.25 using default voltage.

will play more tomorrow and benchmark some then.

etoh

Received the Northwood 1.6A on Monday.

SL668
Dated 01/16/2002
Made in Malaysia

Dropped it onto the Asus P4B266-C. Posted, booted into W2K at 133FSB, 2.13GHz at default voltage. 😉

Heatsink: AVC Sunflower
Memory: Mushkin 512MB PC-2100 Special

No sign of any instability. Run Prime95 for one hour plus. No problem.

I will keep it at this setting for a few day before push it further.

ive got my 1.8A running @ 2.4ghz 1.6v now 😀
(SL63X 12/26/01) this is one sweet chip!

current benchmarks: (im still tweekin 😉 )
2400mhz cpu 1.6v
133mhz fsb
166mhz memory
533mhz system bus

The 1.8A should have no trouble with 2.4GHz @ 1.55V or 1.6V, depending on the motherboard. At the same voltage, the majority of 1.6A's will do this speed as well. A few benchmarks for the 1.6A @ 2400MHz with the P4S333 mainboard and stock Intel heatsink can be found here.

 

[THUGSROOK]

too bad his memory was only clocked @ 150mhz.

the memory in +25% mode (4:5) would be 188mhz
i guess his ram cant handle that. (or he doesnt have that multiplier)
in +33% mode (3:4) it would be 200mhz!

at 2400mhz it needs all the memory thruput it can get.
thats the beauty part of the ddr333 moboards 🙂

 

[Duvie]

what are your memory bandwidth scores in sandra??? I know with the asus p4b266 that with a certain setting you can lock the pci and run the fsb up to 33mhz over 100mhz and it adds it to the 133mhz memory default.

Therefore say a fsb set to 125 will run the memory at 158...I guess it is just a hosk clock + 33mhz...

I wonder if these chipset suffer from lower scores when ran asynch...like the iwill xp333 boards and such. Anybody know?

 

[THUGSROOK]

its not a "+33mhz of fsb" - its actually a "+33% of fsb"

good P4 DDR333 motherboards have 5 memory dividers/multipliers.
they are... (CPU:MEM) 4:3, 1:1, 4:5, 3:4, and 4:5

if the cpu is a stock 100fsb it would look like this...

4:3 = 75mhz memory
1:1 = 100mhz memory
4:5 = 125mhz memory
3:4 = 133mhz memory
3:5 = 166mhz memory

now lets overclock it to 125fsb, and it would look like this...

4:3 = 94mhz memory
1:1 = 125mhz memory
4:5 = 157mhz memory
3:4 = 166mhz memory
3:5 = 208mhz memory!!!

now lets goto 133fsb, and it would look like this...

4:3 = 100mhz memory
1:1 = 133mhz memory
4:5 = 166mhz memory
3:4 = 177mhz memory
3:5 = 221mhz memory!!!

and just for the sake of arguement, heres what a 150fsb would look like...

4:3 = 113mhz memory
1:1 = 150mhz memory
4:5 = 188mhz memory!!!
3:4 = 200mhz memory!!!
3:5 = 249mhz memory!!!

hope this helps 😉

<edit> fixed my dumb arse typos 😱

 

[Duvie]

helps a lot...

I think the 150mhz chart for the 4:5 should be 150:188, right?


Anybody want to guess whether or not the crucial can take 166 if it given a bit more of juice...

1.8A on Abit BD7, now currently 122FSB at 2.2Ghz with stock voltage, stock cooler and Arctic Silver 3 in an SX1040B case, only running around 4-5 degrees hotter than stock speeds, I'm still only at around 43C full load.

The stock intel HSF is a bad ass performer, just lap the base with some sandpaper and put some arctic silver 3 on it and it'll perform like a champ, not even gonna think about getting a 3rd party one until it really whoops this one's ass, all the others out are worse or only a few degrees cooler than the stock fan in all the tests, not worth the extra money for the already cool running northwood, BTW the stock fan is not at 2900 rpm all the time, it speeds up as the temp. goes up, you can also up it's speed with utility programs.

 

[EtOH]

My 1.8a is stable as a rock right now. running 2.4 at 133 bus without flinching. Had to bump the voltage up to 1.65V to get it though, 1.6 just wasn't enough. Stock cooling seems just fine.

Will report later with temps and such if desired.

I must have gotten unlucky. 🙁 I can't get to 2.4GHz at 1.65... plus after 2.25GHz the machine doesn't shut down and restart properly. Weird thing is, I am using the same board as you.

I always get unlucky when getting processors. 🙁 Not worth it to try another though.

 

[EtOH]

Mine doesn't shut down properly either, I think I saw a few other mentions of that issue with the Gigabyte boards on other forums. Over about the 130 fsb when I shut down it gets out of windows but never turns of or restarts. Have to cold boot it to get it back up, its annoying but not a huge issue as long as you don't shut your machine down.

As far as having a slower 1.8 make sure your memory settings are messing you up. Make sure that when your bus is a 133 that your PCI/AGP is set to 33/100 and your memory is set to 266. I noticed the 8irxp is a little confusing with the dividers and async modes.

[Jgtdragon]

I ordered the 1.8a and the p4t-e from z-buy. I know I won't hit the mark you guys got, (dang, rambus! 😉 )but I am happy with 2ghz with default voltage.
