Hello, the last saturday at 7pm, i'am a little bored and angry with mine e4300, because can't stabilize 3.472mhz:( and i've lapped one month ago, and only gain 1-2º Celcius) (FINALLY I DID IT, E4300 @ 3472 MHZ)
So I think, that i have 2 options:

A) Remove IHS, (to much danger):down:
B) Sanding the IHS a lot, so the IHS goes really thin :up:

I started lapping with sandpaper of 400, but I think, that i'll take a lot makes thin the IHS from that way, so I think, on something more faster, and it comes to my head some stones, one called Laja Correntina Amarilla (here from Argentine), its very rough and soft, so its perfect to spend the IHS. Now, here some pics of the stone where i passed my e4300:

After a while, with the IHS with less thickness, I continue with the normal lapping, passing 400-600-1000-1200-1500-2000-2500 sandpapers

Results:

Well, you probably ask, if this works? If passing a processor over a stone will get good results?
piedra?

Here the results:

After the hard lapping:

How can be appreciate, I win 4º Celcius less on full load, passing Orthos, over the same conditions, and voltajes. And one more thing, y passed orthos without letting settle the Artic Silver Ceramique for 10 days, only settle for 12 hours, so the temps probably will goes down a few deggress more in 9 days

And here my goal, passing stability for more than 6 hours on Orthos:

Bye:D and really sorry for my bad english :( :(

This shouldn't be in Xtreme Pi...

Good work on lapping, but 3,4GHz stable e4300 is nothing too 1337...

i know, my mistake, i've sent pm to the moderator, some hours ago

almost 3.5 (3472mhz)
whats means 1337 ?
thanks

1337 is nerd speak for extreme, or elite. pronounced leet. 3.4ghz is not much - good cpus on air do up to 4ghz.

good job! 4c temp drop is definitely an accomplishment
i'd love to see some pics of how thin the IHS is though..

ahhh, now I understand, thanks :D.
Well i don;t know so much, but for and e4300 with an TT bigTyp vx, it's not so bad number, I've been looking this ranking of all c2d with stable OC for more than 6hs on Orthos:
http://www.hardforum.com/showthread.php?t=1138241

And looking the e4300, only 2 was hihger, at 3.6ghz and with motherboards with 680i chipset, mine its 650i, and one of then with WC Sfiwtech Apogee GTX, remember its orthos stable my config, not only for the screen :up:
And i forgot, i used on BIOS 1.51v, but with the vDroop on full load, was only 1.464v, and looking that list, the ones at 3.6ghz uses 1.60v. And they are other at 3442 with same motherboard and a Sfiwtech Apogee GTX, using 1.54v.

I post one pic up :)

Nice acomplishment.

Some guys here seem to forget it's only an E4300 that runs 1.8GHz stock, so 3.4GHz isn't bad at all for such a cpu.

Still 70C is pretty hot for the vcore you're pushing.

Thanks man :D :D :D

I have put an offset of 15º celcius on the Speedfan, because I think that the real temp of the e4xxx its the same than coretemp 0.95, but how the speedfan mark the same that coretemp 0.94 (15º than 0.95), i put that offset.

But, i've then my e4300 at 80C :D :D , I've the e4300 with and alarm, that an 81C, shutdowns the PC, just in case :p:

Congrats, not bad considering you used a rock! And that's a pretty decent OC, for a 130-dollar chip. But like already stated, be careful with those temps... may want to get some non-TT hardware. I did. Never again... :)

when i was testing some e4300's i got much better oc with the pin mods .

jajaja, thanks man, and the rock did a good work on the lapping process:p: . Respect to the temps, yes, they are a little high, but will probably goes down 1-2º C more, because it's ASCeramique and takes 10 days to complitely settle, and i only let settle the ASC for 12hours only. On 9 days i'll probably test again to compare the temps



when i was testing some e4300's i got much better oc with the pin mods .

Hi, with wich motherboard used? What pinmod did, 1066 o1333? How much better OC, how much mhz more?
Really thanks :D :D :D

Actually removing the IHS isn't that dangerous, easier (smoother cut) and no smd's compared to AMD.

The problem with hot E4*** chips is the goo application between core and IHS, so there lies the real gain.

With your great clocker you should gain even some more, and most definately lower temps.:up:

I don't was so handy, so scary me a little to remove the IHS:(
