First try at OC'n

[Sunin]

oh I misunderstood, I thought you were talking about what vcore is being supplied by the mobo if bios is set to x.xx
ur complicating things man, you really dont have to figure out the vcc, just run prime and if prime fails it means the vcc dropped too low and the cpu missed a 1

D

I don't get errors in Prime, that is the problem it just locks... I'll be interested to see the impact of the DDR500 ram on this system.

Using memtest I've determined memory max is 225mhz, and timing of 2.5,3,3,8 ran for hours without a single error.

So then I played with the 5:4 ratio and could not get it solid over 242, just staying stable period... not pushing the cpu with prime or anything. Just to see what the max FSB I could set it at period... everything above 242 would reboot.

Ah well more fun on Tues when my memory comes in!

thing is these EEs dont usually OC that much, try backing it up a bit, say to 3500

3.6ghz with 2.5,4,4,8 mem is stable for 30 minutes in prime, so that is where I left it, just wish I could get over this hump, not sure what to try next if anything. Well if nothing else I've increased system performance by about 15% and made my processor alot happier with proper cooling! All good learning experiences!

its all in the name of fun , otherwise it wouldnt be called a hobby

you need to run prime for more time man and if it errors or hangs you need to lower the oc, an unstable machine is no fun

Will do that today... I've been more futz'n around with trying to figure out where the limits are and playing a few games on my days off. Again thanks for your help!

I'm on like 4hrs of prime... how long do you suggest running it? I had to come down from 225, as it locked after an hour... I guess I can let this goe for a day, temps are under 50c and that is with the fan on quiet setting. I'm seriously considering buying a new processor to play with!!!

 

[Sunin]

Some Final Observations:

WHEW its warm over here! with the new Zalman 9500 the amount of hot air be expelled from the back of my Sonata has increased at least 3x... I know that is good but hell I don't need to turn my heat on in this small 600 sqft condo!!! LOL... Sound is a lot quieter then stock HSF, something with those metal fins just made an awefully loud racket!

I usually run the final oc for 24hrs

P.S. if you want a new cpu you'll need a new board as well

u think thats alot, try running 3-4 comps at once, in summer time

Cool I've got 221.49mhz oc running for nearly 14hrs now, solid as a rock...

And a new processor does not a new board necessarily mean. SL7PM are supposed to overclock very well it is a 478 socket processor. For about 188 I could see 4+ ghz. Its very tempting!!!

the problem is the p4c800 was made before the prescott came out and it doesnt have a good support for it

2x1g DDR 500 mem in, no real change in pcmark a 10% increase in fps etc... but nothing huge....

Decision to buy Pentium M 760 to play with. From threads read and various discussions I should be able to modify my MB and get a decent stable OC of about 3.2ghz out of it. With a drop on my superpi score from 36.5s to 26s...

Realizing the P4 is a sucky processor overall! the 3.2EE is even worse for OC'n so this new processor should be a good base to really learn OC'n!

Should have the new processor Thurs or Friday! Will be a fun OC'n weekend!

First - P4s are far from "sucky", most current bench records are with P4s

Second - dothans are indeed fun to play with, but you need a ct479 adapter to use one on a regular s478 board and they have their weaknesses too, they are built on p3 technology, have no ht and a lower fsb and even though fast in some benches, overall you will loose performance

Don't think I need the adapter with the 478 socket version... that was with the older mobile version which was the socket 479... It will be fun to play with and I can side by side compare them to what I have with the 3.2EE. Ok not sucky but the EE OC's like CRAP...

they are called s478, because both have 478 pins, but the pin config is different and you do need an adapter

unfortunately EEs dont oc alot, but they are very nice cpus and a EE at 3.5 will give you more real life performance than a oced dothan

I'm totally confused now! This Says nothing about it being a 478s, now the older 479s was a different pin... am I missing something?

Also intel's info on the processor

s478 comes from the number of pins, p4s and pMs both have 478 pins, but they have a diff pin config and therefore some call dothans s479 to avoid confusion (unfortunately not everyone does this)
you can run a pM on a few boards designed to run pMs for small factor machines or on a few asus boards, but only with the help of the asus ct479 adapter (which is rather hard to find these days)

So your saying the ones that say 478 are different then normal socket 478? Grr I was under the impression that the CT-479 was used to convert 479 pin versions to the 478 socket... and that the 478 versions were plug and play drop in's for the 478 socket...

Back to researching... grrr

Intel makes two dothans - one with 478 regular pins and one with 479 bga (ball grid array) pins, the s478 can be used on a regular board with the help of the ct479 adapter, the bga chip cant be used on a regular board at all

zipzoomfly has the CT-479, ordered it... wish I would have known this this morning cuz I had originally ordered the CT-479 but cancelled after seeing the info on intel's sight... Ah well I ordered it and sent it over night... so hopefully by Friday I will have both

hmmm didnt know they had it, wow $50, it hurts

man I see ur sig already says dothan, stop doing this
btw did you already mod the board or are those same as the dothan ? you dont need those mods


D

PS: hey about that crappy EE, send it my way, seeing how you dont need it and its so crappy

Have not moded the board yet, plan to down the road as my OC'n hits its limits... I do plan do the vcorre mod on the CT-479 so I can run up to 1.75v
