E6600, can't get stable at 3.6ghz (400x9) FPO#L632B086

What VID does coretemp say for your cpu?

Mine says 1.325V VID, I guess your cpu has a lower voltage at default.

1.2375 VID

james32 · 2 Mar 2007 at 16:22

yeah i noticed people with startup vid 1.35 usually max out
3.6

my 6400 has a startup vid of 1.35 which is way to high for
my chip as it runs happily at 1.28 volts right upto 3.2ghz

think intel are starting to see this with the newer chips
so there lowering the startup vid.

With the pencil trick on the P5N-E can you use any pencil? As far as i'm aware no pencils contain lead anymore?

smsmasters · 2 Mar 2007 at 16:55

I guess the trick to find a great overclocking core 2 duo cpu is the one that has the lower VID to start with.

marscay · 2 Mar 2007 at 18:52

yep pretty much.

here it is @ 3750 1.4v

Me is planning to get an e6600 as well. Hows the OCUK batch for e6600s. And did u like buy 4 of them to get the one with low VID? Let me know whats the best way to get one with a lower than usual VID.

Thanks

no it's my only c2d chip, it's a raffle mate ...you buy you try ...sometimes you luck out and sometimes you don't.

your best bet is to buy from B&M store so you can at least look at the batch/stepping....but in general most recent processors are clocking nice.

your cooling is a factor too, mine's running under high-end water which tames the temps a lot.

Thanks. What batch/stepping you think I should go for?

any recent revision B seem to be doing pretty good.

Like this.

Don't tell me this is on air.Isnt this B4?

Yes on Air, and yes a B4.

If you like do a google search for the stepping l629B475. I guarantee you won't find many (at least not in the UK

) and the ones that you do find will be running cool, with low volts and with an average (Orthos stable) OC of 3.8Ghz+.

Also, don't read to much into those temps as I made sure my room was *freezing cold* at the time of benching. I'd catch pneumonia if my room was that cold 24/7.

Below is a pic of my normal stock (nearly) idle temps:

smsmasters · 3 Mar 2007 at 11:23

I've just replaced the stock 120mm exhaust fan from my thermaltake soprano case with an Antec Tricool 120mm led at full rpm and my load temps in orthos are ~60-66C.

Not bad

I'm now below 70C, I'm going to see if I can lower the voltage some more.

Just sent u an email regarding some details which you obviously cant answer here.

marscay · 3 Mar 2007 at 18:06

is it just me who finds it hard to believe a c2d @ 4ghz with 1.5v+ is sitting at 52c running orthos on air?

on that 2nd pic your idle is 19c ...my chip under a PA120.3 with the window open never goes below 24c at stock ....

where are you iceland??

netby · 3 Mar 2007 at 20:31

yes it´s possible

my room temp is at 18ºC
pc case is closed (Antec Solo)
and Ido not live in iceland

w3bbo · 3 Mar 2007 at 22:55

Something deffo aint right there tbh. A cpu will be more than 6c above ambient temp even at stock speed and vcore, you sure it was 18c? Not calling anyone here a liar or anything like that it just seems very odd, especially Bizzarres shot of 13c on air lol.

Dude believe what you want, I'm not out to prove anything to anyone. But what I do think you need to understand is that this wasn't a run of the mill air bench with only a couple of 80mm fans. It's what most enthusiasts call an 'extreme' air run, as my rig consisted of 3x120mm intake fans (running at 2100rpm/80 CFM), 1x120mm outake fan (running at 2100rpm/80 CFM), 1x200mm outake fan (running at 800rpm/134 CFM), 2x40mm chipset fans (running at 5200rpm/6CFM), and of course the Tuniq Tower's stock 120mm fan (running at 2000 RPM/80CFM?). I'm not sure of the ambient room temperature at the time but as stated it felt *freezing*. Also take into account that I was running a 8MB PCI card so there was no extra heat generated from a 3D card, and last but certainly not least, my E6600 seems to be a naturally cooler running chip than most. Admittidly my system sounded like a hover craft but to be honest my aim was to achieve 4Ghz stable, not to achieve it whilst running silent.

Just for good measure here's another pic of my stock idle temps for you to question/mull over.

One last thing, I'm based in 'Newcastle Upon Tyne, not Iceland, smart ****.

netby · 4 Mar 2007 at 00:16

yeap is truth

but the cpu Vcore in my case is 1.15 ,cause I have the Asus bios energy savings ( d´ont now the exact name) activated,so when idling the cpu Vcore go down to 1.15 more or less

and belive me the case is closed and fans at minimum
Antec Solo closed make a "tunnel" of airflow,it´s a short and small case with two front 92mm fans a one 120 fan at rear

yf you ake a look in the pic above,you could see the rear 120 mm fan is at one inch of the TT 120,and above it is another fan, a 140mm fan (PSU fan) at one inch too

so this two fans ,so near the cooler,act like an " integrated" system,if you now are I mean

and for the room temp,yes I have a digital thermometer( sorry if this is not the right name in Eng.) wich is at 15 feet of the pc ( in my bedroom- next to the room who is the pc) and during the day it stays at 18/ 19ºC)
I can´t take it near the pc because it´s atached to the wall with a outside probe - but i do not feel any diference when i leave this room to the other room ( maybe 1/ 2ºC more or less)

pic of the digital probe:

( ps - I put a lamp near it for the photo and the temp went to 20ºC ,but in reality it´s 19ºC)

prtscreen with all th cpu programs :

sorry i forget this:

That 13c/15c shot was taken straight after a cold boot, and in the middle of winter, and after my system hadn't been switched on for a couple of days. Is that so hard to believe?

As stated in my last post, I'm not out to prove anything to anyone, so I'll make this my last post in this thread.
