<< Heres the Prime95 benchie results for those that care... >>


You know I do....! How many hours did u left it running eventually? Did it give u any errors?

 

[THUGSROOK]

at this point, IMHO 166fsb is 100% stable @ 1.69v (1.7v setting).

im not a big fan of Prime95, but just out of curiosity i let it run for 2 hours - error free.
i wont add voltage, kill my system, or go crazy over Prime95 - but eventually i will let it run for as long as it can. ill post those results when completed.

i also ran some of those promised HD benchmark in hopes of finding out if there is a 1/5 PCI divider somewhere. the results showed nothing obvious, but does hint that there may actually be a 1/5 divider at 166fsb and maybe even 150fsb. ill keep trying to get more info on that.

 

[dbal]

I totally agree with you thugs-u know Prime gave an error in my o/c after 7 hours bit I don't care much either since for 5 days now it's been extremely stable in heavy use plus the all night run of 3DMark2001. I would be 1000%confident if Prime was ok for 12hours + but it's ok. 100% confidence is also enough for me!

Hi Thugs you got a great cpu there , nice to see it ran well under stress tests. Congrats.

Superman CK,
What host:memory ratio are you running?

Currently, my system is stable (5+ hours on prime95) on
150fsb, 4:5, Corsair xms pc2700 512 CAS 2-3-3-6
all default voltage and 42c

 

[THUGSROOK]

JTKGY there are no ratios above 132fsb on a P4B266 board. hes running 1:1.

 

[Nighthawk69]

I just wanted to say that I ordered my 1.6A, P4B266-C and 512MB Samsung PC2700 from NewEgg and it shipped today... it should be here Wednesday!!

 

[THUGSROOK]

Nighthawk69 thats great - let us know how well she does
very interested in how well that Samsung runs too.
its only rated cas2.5 but ive heard some really great things about it.

gluck

 

[DinoGucci]

hahah

 

[THUGSROOK]

whats so funny Dino?

 

[Nighthawk69]

Will do I also read a lot of good stuff about overclocking the Samsung PC2700 and that's why I elected to go with that over the XMS2700 from Corsair (also because it's cheaper too) and if I can get the same overclock for cheaper, well I'm there

 

[DinoGucci]

you got the whole forum to buy the P4B266-C including me heheh
you should be an asus/Intel salesman

 

[Nighthawk69]

... and now I have everything together to format. Bring on the overclocking!!!

 

[SupermanCK]

My mem ratio has to be 1:1 since it is over 132 MHz...
Anyone got the BEEPING once they overclock???

 

[THUGSROOK]

DinoGucci hahahahaha

Nighthawk69 well be waitin impatiently for that thread

SupermanCK ill plug a speaker into my board and see if it beeps for me or not. (i never leave those things in my cases)

 

[Richardito]

Removing the 'aluminum foil' (i.e. graphite thermal transfer sheet) did not destroyed the HS. As long as you are using a thermal compound it should be OK.

 

[THUGSROOK]

SupermanCK no beeping as of yet. (except for the single "beep" while booting) ill msg you if it ever does.

BTW: you can use an LED light insted of a speaker

 

[SupermanCK]

Thugsrock - What do you mean by I can use a LED light instead of speaker?

 

[THUGSROOK]

i know alot of ppl that hate hearing that speaker but still want to be able to recieve visual msgs from it.
i had them hookup one of their xtra case LEDs (HD2 or 3 etc) to the board insted of the speaker - they are much happier with it that way.

 

[SupermanCK]

thug - where exactly is the other hdd led at on the p4b266-c?
I think i rather do that cause i am sick of the beeping...and i want to play around with the FSB at night...but I can't cause my gf is sleeping most of the time

 

[THUGSROOK]

no no no - you have it backwords.

take a case LED and plug the leads into the same 2 connections that the speaker used on the board.
the LED leads will need to be the "split" type so they can spread 4 pins away from each other. (like the speaker) take a looksee in the manual, youll see what i mean.

 

[SupermanCK]

thug...how did you split the case LED connector then?

 

[THUGSROOK]

i guess you dont have the "split" type huh?

cut the wires and splice them together so the LED has the speakers connector. doesnt matter which wire goes to which.

 

[THUGSROOK]

<< UPDATE >>
altho i was 100% stable w/1.69v, on a whim i decided to up the vcore another notch giving me 1.72v. i re-ran all my benchmarks and they all ran faster - so ill leave it here @ 1.72v

i also tested the Normal/Turbo1/Turbo2 options in the bios.
Turbo1 mode ran noticibly faster in all benchmarks.
Turbo2 mode ran noticibly slower in all benchmarks.

im still not certain, but i think Turbo1 may have "PCI lock", and Turbo2 may have "PCI & AGP lock". being the gamer that i am, im using Turbo1 mode

any P4B266 owners have any info on this?
