P4 1.6a. How fast can it be pushed out of the box?

[LogisticalBovine]

>With no RAM burn (Samsung True 512mb PC2700), no CPU burn (if there is such thing), straight out of a box, new board, new cpu, how fast are you able to push this CPU without it frying? I've heard 2.1-2.4ghz right out of the box with a stock HSF. I'm going to be running this thing on a Thermalright AX478 (AX7 model for socket 478) with a Vantec Tornado (84.1CFM goodness). Parts are starting to arrive and I can't wait to slap on the AS3 and overclock this baby on my ASUStek P4B533-V motherboard. I'm planning to hit at least 2.0ghz right out of the box, just to make sure I got a good deal on this processor.

>One more thing. Can someone e-mail me or post a detailed, step-by-step explination of what the 3:4 trick is on this board? I'm probably going to stay SPD or 1:1 as to not kill my RAM but I want to know for future references.

Thanks all you Anandtechies.

Right out of the box you should be able to do 2.1. I ran mine at 1.6 for maybe an hour while I loaded my drivers then it was up to 2.1. I set my ram at 3:4

i was able to get to 166fsb on my 1st day. on the 2nd day i went to 170, 175, and 180fsb.
the performance curve drops off hard past 167fsb, so i settled there.

HTH

There are many of us that believe that no "burn in" is (ever) necessary for a CPU. That is will do its maximum performance immediately if all other variables are right.


There has been many a discussion on this in day of yore here. Do a search of the archives if you don't believe me.

i agree with that.

ive had my 1.6A for 2 months now - it doesnt overclock any better now as it did new.
however i do think that memory and motherboards do require a bit of a "breakin" period.
nothing harsh, just typical use for a couple days til it gets "settled".

I dont know about a burn in but you might want to take a few minutes to make sure the heatsink is mounted right and check the temps before/during/after overclocking.
BTW, Mine went to 2.1 the 1st day and to its max 2.35 the next day.
good luck

sorry LogisticalBovine i forgot your other question...

you dont need to hack for 3:4 ratio - it already has a 4:5 ratio.
a 4:5 ratio is actually better for ppl that could run 160fsb 400DDR.

 

[LogisticalBovine]

What is the 3:4 good for then?

 

[THUGSROOK]

for ppl that cant run 155+fsb

my 1.6A run 2.4 out of the box with the retail HSF and default vcore (1.5v).
using nearly the same mobo p4b533 with DDR 2700 samsung original

Umm ati Radeon VE

But I was just wandering What are the setting/some good settings to Use to Overclock!! Since we have same mobo Maybe U can help me Tanks!

Mine ran 1.6@2.4 too at default 1.5v...wasn't prime stable until 1.55v....I ran it up to 2.46 first day and win98 FE limited me (still does)...slap in winxp and I went to 2.66ghz (167fsb) with 1.66v actual...Will post and load into windows and run a few benchmarks at 2.88ghz (180fsb) w/ 1.79v actual....so I guess for most that is probably calling it stable... However I haven't prime tested and likely wont until I am about ready to get a new one....


I have left it at 2.66ghz for reasons my mentor Thugs states as well as I don't like the heat and the voltage for myself personally....

I would love to get a hand on a 4:5 ratio board so I can run 400+ mhz ddr out of kingmax that did it on my asus p4s333 mobo....

I just got mine up to 2.4, stock hsf, and I haven't upgraded my case or case fans yet (4 years old).
