Damn That Elusive 4 Ghz!!!!!!!!!!

[Achilles17]

sigh...why must it be so hard? i got my 3.0C (30 cap SL6WU) up to 3.98ghz at 1.6V...but I CANT GO UP JUST A LITTLE MORE!!! damn it...well, 3.98 is pretty good i GUESS (265 FSB)...3.99 (266 FSB) booted to windows, but crashed immediatly. yeah, this probly isnt too stable, but im on it now and it seems fine, ill prime it overnight at 3.8 or so to test. oh well, heres an SS of 3.98 (ARGH!)

Man, that's excellent! Sooo close. Did you just install it? If so, I think you'll hit 4GHz once it gets burned in. Congrats on the great oc! :thup: :clap:

[Achilles17]

yeah i installed it about 18 hours ago or so. thats a good point, i forgot about the burn in...how much more does one usually get after waiting a day or two? btw i used AS5, and i heard that has a burn in time too, is that true?

oh and btw, im runnin this 1:1 with a gig of OCZ PC4400...heh...

[DocLiv]

I got 7 more fsb on mine after a couple more days. Not a huge diff., but enough to get you that 4GHz. Man 1:1 :drool: What's your Sandra look mem bandwidth look like? I'm so jealous. I got to get me some. :D

[unreal]

wow not bad at all..this cant be air cooled... thats crazy.. good job.. keep us posted.d.

[Achilles17]

it is air cooled, SP94 + 92mm Vantec Tornado. The Tornado is only at 2500prm though, about half speed, so its virtually silent. Heres my Sandra mem bandwith at 3.8ghz, at 3.98 its a little higher, around 5770 i believe. Anyway, here it is:

Wow, people are getting some crazy results with just air cooling lately!

Wow, people are getting some crazy results with just air cooling lately!

its all suicide runs though. With my old 2.6c, I could hit 3.8 on a banzai run. It wasnt at all stable, but it sure did make nice photos.

That's 1:1? That's much lower than I expected. I get 5644 with the 5:4 divider. I thought you'd be well over 6000. You must have some really relaxed timmings.

[Achilles17]

its not a suicide run btw, its runnin at 8ghz perfectly stable, ran prime for maybe 6 hours without errors (ill run it for 12 a little later), so it works. and yeah, i dunno why its only at 5600, but whatever. timings arent relaxed either, 3-4-4-8, ill look into that

when you run the benchmark make sure everything is closed and not running program wise.

many people have a hard time believing 4ghz on air. i dont see why its so hard to believe? but the OC looks great man!

heres specs:

3.0C@3.8ghz
SP-94 + 92mm Vantec Tornado
P4C800-E
2x512 OCZ PC4400
Xaser III Super Tower (V1000D)
Audigy 2 zs
X800 XT (hasnt arrived yet, still waitin on this, have a ti4200 in there for now)
200gb SATA

temps are about 38/46, pretty damn good. The tornado is on a fan controller, so it adjusts to the temp

[Achilles17]

i actually meant 3.8ghz, 4 boots to windows, but freezes soon after. hopefully after a day or so it will start to free up, maybe i will be able to hit 3.9 stable...

[deathstar13]

looks good! depending on what thermal paste you use it may settle more and give better temps and allow the higher oc.you need to let the pc cool at night and run during the day so it sees temps extremes to get it to settle faster.

my point exactly, although suicide runs are fun

[Achilles17]

I used AS5, so that should take some time to settle too. i only installed this about 18 hrs ago, and it hasnt been on the whole time, so it hasnt quite burned in yet.


my point exactly, although suicide runs are fun

yeah, but i just wanted to say that i did hit 4ghz, but i still dont have a damn screen of that :cry:

4ghz?! Thats freakin slow man

5 g's is where its at :eh?:

[ed.howell]

I did it!!!! But look at the voltage it took. I obviously did it for bragging rights as it will not prime nor do I want to run it at this voltage for long.

I have a question though. I am thinking that I need a voltage droop mod. Or maybe some faster ram. When I put a load on it the voltage drops about .12-.17. What do you guys think? I have an Asus P4C800E-dlx and my PSU is an Antec Trueblue 480W. The memory is Hynix D43 PC-3200 ram running at 1:1 3-4-4-8. I tried at 3-3-3-7 but windows wouldn't boot at 236 fsb. Also I tried 5:4 and windows also wouldn't boot it liked 1:1 but maybe I don't have enough voltage. Bios only goes to 2.8 and thats what I have it set at.

I also tried to boot using 1.7 vcore and it wouldn't boot until I set it to 1.725 vcore.

Let me know what you guys think. Your help is appreciated.

Congrats Ed! Way to go man! :eek: at the volts though.

5GHz pfffffft! Who wants something that slow when you have 40GHz! LOL ;)

[deathstar13]

I guess I have to figure out how to get a good picture posted up here.i can see the pic enough.
dont be useing that voltage again or your cpu may do something you may regret.
anyhow you need the vdroop mod badley thats why its taking so much voltage to get it to 4ghz as its fluctuation way to much.
the psu is fine im sure.

the ram doesnt like 2.8vdimm anyhow.
2.7 is the sweet spot.
i max my bt-d43 at 265 3.0-4-4-8 1:1
235 5:4 2.5-4-3-5
may do 200 2.5-3-3-5 i dunno didnt try.its rather flexable ram and runs great and it doesnt respond to high voltage or at least mine dont.

Maybe a droop mod would solve all your probs. :)

Thanks guys. Any idea on where I can get my motherboard vmodded? I am not very good with soldering. How much fluctuation on voltage will I get after I get the board modded?

Thanks again you guys are very helpful

Is it common for most prescotts to be good overclockers? I have access to 6 3.2E chips for my picking and am thinking maybe I should try those if this 3.4C doesn't work out for me. What do you think?

[deathstar13]

What do you think?NP man everyone here is helpfull in the same way as i.i could have never,ever gotten as far as i have without them.

stay with what you have atm,do the droop mod see how that affects it.
granted i cant tell much about the oc ability of the chip.its not in my hands so its even harder and can only make guesses.

but at the moment it isnt looking great.but a mobo with issues is worse than a chip that isnt a great ocer.so fix the mobo and more can be seen.

asus guys will hate me for this but can you send the mobo back and mabey exchange for an ic7? the asus is great once modded but the ic7 is great outa the box imo.

if your staying on air i suggest staying with the C chips.they seem to oc better as they run cooler,and cooler means better oc ability.

prescotts do oc better imo.but bring many issues with them.
1.higher heat
2.high stress on the mobo power circuits.
3.need mobo sinked out "IE" if its warm it gets a heatsink.
4.need very strong psu.

this may change as i see some possabilities of some DO's sneaking in soon.
supposedly they run a tad cooler and dont use as much amperage as the current CO prescotts.
these are what the new lga 775 cpu's are,but are almost impossible to find in socket 478.look here in the intel section you will see some of our search struggles that are on going.

[ed.howell]

Deathstar,

Is your IC7 modded? I am wondering if I switched from my Asus to the Abit would I have to get the IC7 droop modded to do what I wanted? Also if you switched motherboards would you have to reinstall windows and all your software.


PS.. I got one of the 6 Prescotts I was talking about to boot into windows at 3.92GHZ at 1.5vcore. That was just a quick test on a 400Watt PSU and the stock heatsink so I did not do any testing on it. Would you need to do a droop mod on the Asus board with the Prescott? Also what kind of things do you need to do, besides goot CPU cooling, to make a Prescott run this high with no problems?

Thanks a lot

Ed

wooops sorry i missed this post but caught the bump :)
feel free to pm me also for direct questions i dont mind them either.its just alot of times when posted they help others is all.

the only thing done to my ic7 is i have heatsinks added everywhere.
no volt mods atm,altho id like my vdimm modded to get over 2.8vdimm but that requires a vtt mod also.not a big issue tho,and really isnt needed unless i do hardcore ram ocing.
the ic7 seems to have a much more robust power sircuit for the cpu and doesnt need the vdroop mod.
some will say yes you need a windows install when changing mobos.
but long as the chipset is the exact same i say its ok to do.just reinstall the mobo drivers on the new one.
i swicthed from my epox p4ca3+ to this ic7 and didnt reinstall windows. i have no issues i can see.but id bet id get better performance if i did,which i will as im adding 2 raptors in raid0 in a week or so so thats why i did worry about reinstalling yet.

on your asus the vdroop mod will depend on how the mobo is handleing the cpu vcore wise.
if you start seeing big vcore swings like 1.5vcore drops to 1.42 and back up thats bad and needs droop mod.
also if the bios setting is undervolting way to low.this is best to ask the asus gus as they know the mobo better then i.

to run these at the max i suggest these things
the thermal take 112 tower docliv is useing looks great for these.
heatsink all mosfets and the pll. and add a fan over them.
make sure that psu is strong and high quaility as 400wt is pushing it bad for a precott but may be fine if its an fsp or antec.
get some good thermal paste of course. ceramique or as5

the one doing 3.92 at 1.5 looks promissing.
i wouldnt go over 1.55vcore myself and i use a prommy but i dont think much is know about whats best for a prescott vcore wise.
i do know id never go over 1.on your 6vcore tho.

[ed.howell]

Thanks again deathstar, no apology needed

That 3.2 Prescott I tried out on one of my computers at work thats why it only had a 400watt PSU, I think it was an Allied, not very good I don't think. I am going to try it out on my home computer-the one in my sig-probably pretty soon. I just installed the Hyper 6 so I don't want to take it apart just yet. I think this is a good tower too for cooling. I have had good results with it so far. I want the AS5 to settle in on this 3.4 I am going to do a droop mod first to see what I can push this 3.4 too. I am worried about the stress on my mobo with the prescott so if I can make the northwood scream I will do that.

[deathstar13]

i missed you had that hyper6 its just as good imo as the TT 112

i think with a droop mod that C will oc better also. it will see less high voltage spikes and valleys and you can lower the vcore overall.

the prescott is a stress on a mobo when maxed out,thats on a ic7 also.but the asus with a vdroop mod should prove to be just as good.
so yeh id do that mod and see how the C does then before swapping.

btw how high you had that ram 1:1? i like mine also but maxs out at 265 2.7vcore 3.0-4-4-8 and doesnt like higher voltage.
great ram for something sold as 2700 on my end.

[ed.howell]

The highest I have been able to get it because of the droop mod issue is 236fsb at 1:1 and 2.75 volts. I have noticed that it does not like 5:4. 3:2 works but who wants that. When I got it to boot a 236 it would boot at 1:1 but would not at 5:4. Weird huh. I have my timings set at 3-4-4-8. It would not even post whenever I changed the CAS to 2.5. I had to reset the CMOS.
