So far both CPUs seem to be kicking tail.
but why are OCs so low ???
3.2 on air is great but why is it taking DI and LN2 to reach 3.3-3.6 ghz???
whats holding back these CPUs ???
voltage ???
FSB wall ??
poor mobo oc features??
low Multi ??
Yes, they are fast but an AMD can hit 4ghz with a coldbug shouldn't the Conroe hit 4-5 ghz without problems due to being based on a colder moble design & no IMC.
3.2ghz =air , 3.27ghz= water , 3.3ghz= Dry ice sure seems like a wall and an aburpt one too.

It is because of the trade off in the design between Speed and IPC
Fast computers breed slow, lazy programmers
The price of reliability is the pursuit of the utmost simplicity. It is a price which the very rich find most hard to pay.

Modern Ram, makes an old overclocker miss BH-5 and the fun it was
For atleast the Cornoe, their have not been really any good mobos which alow for nice OC or vcore options etc. Like coolaler oced that conroe on stock volts. 2.13 to 3.2 Ghz on stock Vcore, if thats not a good OC than I dont know what is...
***Main System ***
Intel Core 2 Duo E6400 2.13 Ghz @ 3.6 Ghz
Abit IP35-E
4GB DDR2 RAM
XFX HD 5770
3x 120 GB HD
2x 160 GB HD
Antec Trueblue 2.0 480 Watt
maybe it would go higher IF this revision of the MBs with 975x had voltage control... (which is a sad thing if you come to think of)
Then it would go over the 1600 FSB which is the limit of 975x if I remember correctly reading that.
Higher multies could probably help, I'm sure we will see that verified soon.
My hopes are that the Conroe specific 965 chipsets, will have slightly newer and higher fsb clock, so that we wont need a high multi or XE to get a over 60% overclock

I hope we'll see some good mobos
based on universal tact generator chip (maybe it can increase max FBS due to better sync. e c.t.),
BTW I suppose most of 965 mb will use this as well as new 975 (like DFI...)
You are kidding right?
The motherboard selection is very limited.
The CPU's are engineering samples
We havent even seen conroe EE ES yet
you will see 4ghz intel conroe with 1500mhz fsb. Just wait until they launch some products. Plus, look at how well they scale in terms of performance as you raise the freq. They are very well designed chips.
Consider everything you see now just a PREVIEW of what is to come. I dont know how you can compare how two totally different CPU's. Its like saying, Intel 9xx series can scale to 7ghz under ln2, why cant current conroe?
Plus, look at motherboards for 9xx and amd skt 939. Very mature platforms.
Conroe right now is just getting warmed up

QFT. These are ES mobos with NO voltage options. Honestly, read the threads where coolaler posts his results, he said a million times that he cannot change the voltage from stock. The only Merom mobo has an FSB wall, what do you expect?
i didnt know 4ghz amd chips were so common.
for conroe, it's mainly due to the lack of good m/bs, we only saw some results on Intel BadAxe an Msi 975X, none of them is known for its xtrem o/c ability
for merom, we already have 3.6+ cpus, and 14s Pi, with a 2.16G pre-release cpu, I don't find that so bad :d
Sure ill go buy FX60 and clock it to 4Ghz air
I have only seen one AMD @ 4Ghz I think with a three stage cascade system.
Conroe is being tested way before release and is allready alot faster to whats out. Then new steppings will also come out too
These motherboards touch slightly on OC options. It doesnt even have Vcore settings
A few AMDs made it to 4 Ghz but they're all FX57s and Opty 154Sure ill go buy FX60 and clock it to 4Ghz air

Oh i was just making a point
The hardware you need to be able to do it and along with all the mods. Even if someone says dry ice,ln2 or what ever. Thats not 24/7.
A lot of people have hit right on the mark. Conroe is extremely fast and scales incredible well. My 2.13Ghz ES CPU has no problems overclocking to about 2.9Ghz on stock volts. The 2.4Ghz ES Conroe CPUs will go to about 3.2 on stock volts. I'm sure we'll see 3.4 to 3.5Ghz with the B0 stepping 2.66Ghz Conroe ES processors....
The extra cooling above and beyond air cooling is simply allowing for slightly better silicon efficiency and is buying so very little when it comes to overclocking right now....this is actually GOOD news. It means that the CPU doesn't necessarily need extremely cold temperatures to overclocking well.
What we need right now is the ability to crank about 1.5-1.6v through these CPUs. Extreme cooling on a CPU at this voltage will surely skyrocket the speeds into the 4.5Ghz+ range.
I still stand by my original announcement, Conroe WILL get to 4Ghz on aircooling.
FCG
Coolaler did it and was still far from 4Ghz
The results are impressive still.Vcore:1.47~1.5V
holy #^*$%, did you not read a word I typed? Wait for the XE.
I'm not pretending anything but seeing that was on LN2 too, please explain why there will be such a difference in OC. Yours was supposed to do 4Ghz on air, any clue why it didn't as of yet?holy #^*$%, did you not read a word I typed? Wait for the XE.
FCG, I hope you have Conroe XE ES chip under NDA
to be sure it will do 4Ghz on air.
To be honest, 200% max overclock with TOP 965 Presler makes
4Ghz Conroe a bit closer to reality in my mind...... But Who knows how simple Conroe (not best cores like XE) will go?
AnyWay
Lowrun can you not read. these are early es samples, they will only get better.
That was on merom NOT conroe. The mobo had an fsb wall. Conroe remained at stock volts for coolalers entire test.
Coolaler had a Merom - Core mobile (Yonah and now Merom) cpus have a FSB wall, that's why it can't go further.
It doesnt matter what cooling u have if u cant give VCORE = voltage.
Lets say my cpu runs at 30c and i cannot up the vcore, moving to LN2 or any other cooling wont improve my OC because you cannot give extra volts.
Coolaler could have gone higher with AIR. He never said his chip was running 90c and its holding him back.
Remember Intel will be releasing 3.3Ghz and to go to 4Ghz would be easy. Thats my opinion and we will just have to wait and see.
Seriously read FCG's post. It's hard to clock to 4 Ghz when you're on a beta board with no voltage control
As FCG said the Conroes here are an early revision and the upcoming conroes will be a newer revision good for more Mhz
Yep Orcbeast, 3.33 Ghz Intel model. Which means it will run there on the stock aircooling. We have some definite headroom with Conroe.

Wait for new MB to come out... Im sure will get some good ASUS and DFI boards soon. Then we'll see some better OCs. I think its just the boards that limit the OC.
Id wait for a few months when everyone will get the conroe then well start getting somethin...
Its just waitin now
I can read for what i know, that's how i learned from FCC that his ES was supposed to do 4Ghz on air, does it mean that at some point his proc will turn into something else on his own?
I like other people am surprised how well conroe/merom OC on stock volts but seem to not scale that much with volts and i know this is all preliminary, just curious here.
I'm with FCG, new steppings should help alot.
