When should louis stop pushing his Q6600 g0?

my Q6600 G0 VID: 1.2125v

currently got it stable at 3.78ghz @ 1.45vCore.
prime95 24 hours
occt 2 hours
temps at or under 60c with water.

if i want to keep this cpu for 5 more years, is 1.45v too much?
what if i wanted to go to 1.5v? can i get 5 more years of CPU life? (assuming i get everthing stable)

are those voltages (1.45v, 1.5v) bad for the MB at all? or is the 420-440FSB bad for the motherboard? i dont want to kill my MB either.
 
Will it last? Who knows...considering your thirst for hardware you KNOW you're not going to be running this system for 5 yrs. as your main rig. But if you do, log it!

What you really have to ask yourself is...what software are you running that you need that extra ghz for? Are you folding? Are you running primes? Are you searching for extra-terrestrials?

Seriously, how much faster do you load Oblivion (or whatever you're currently running) with 1.45v as opposed to your fastest overclock @ 1.40v?

And does it matter?
 
Nice overclock, but there's no way I would run my machine like that for an extended period of time. If I were you, I'd run it as fast as I could take it without changing any voltages. That will make it last longer than you will be using it pretty much guaranteed.
 
Great overclock, LUISSS! That is truly amazing for a Q6600.

In my opinion, 1.45 V for a 65nm chip is not much at all. I would feel safe even at 1.5 V , especially on water. But, nobody knows how long it will last at that voltage and frankly you are really asking a lot of time out from that cpu. 5 years is something, even for a stock clocked chip, it's probably a lot for a heavily overclocked one. Just enjoy your oc for as long as the chip and mobo lives. When you overclock, you assume some risks and bad things might happen. But in the end, when/if the cpu dies, you can say that you've ran it as fast as you could and that really worth the effort. If you don't think this way, then maybe you should leave it at stock. 😉
 
You are already past what I consider a safe upper limit...but I don't think 1.45 is out of reach. I have never been one to reach for that last 200Mhz as I don't think it matters...but that's just me.

I normally run my chips up to the bottom of the vcore ladder, just to where the voltages really start to climb for additional gains...then I drop down 10% or so...but then I also "require" this machine to work for a living.
 
lol all i want is OCCT (2hour) + prime (24hr) stability @ 4.0ghz, i'm stuck at 3.915ghz right now =( lol

then i'll back it down to 3.7, just so i can say i'm a bit above all those 3.6 Q6600ers! 😉

its a hobby... "are you actually going to use all those 10,000 stamps? are you going to mail 10,000 letters?"

btw, i dont play oblivion, only counter strike source 😉
 
Always push it to the limit this is where you know the limit is and you set your real everyday speed comfortably below this so you (ideally) do not crash or experience program errata in everyday use. It's unwise to o/c within a few MHz of absolute max because ambient conditions always change. It's good to back off a few 100 MHz so you have a safety net for hot days, dust on the cooler, etc. Otherwise your system becomes a maintenance intensive piece of machinery that will take away from real work time. (some express that is becoming a bitch!)
 
well temps are NOT a problem right now, my bottleneck is the CPU stability i've ran my MB at 440+ fsb before with no problem (8 multi) so i know its not the FSB bottling me.

my highest core temp i see with OCCT is 54C. i love this water cooling. (until i get my first leak and explosion)
 
I'm pretty sure you're safe from an explosion if there would be a leak. It's really no different than if you wizzed all over your PC. 😉

Punch it to 1.5v and tell us how high of an OC you can get. It would be nice to know, just because, how high it can go.

But 3.8 is serious good stuff on a q6600. Just for the sake of being sure you're not going to cook it (voltages do this, heat helps you maintain a stable OC but mainly voltages are what kill the chip) I'd leave it where it is.

Per Intel you can safely go to 1.5v. If you don't fold with it, just want the high Ghz, then I wouldn't worry too much about the higher voltage. Keep in mind though, it's going to be at 1.4v 24/7 which definitely will damage it more than at 1.35v. I'd feel much better at 1.35v than 1.4.
Personally, because my mobo does not have LLC, I have to run at 1.53v (1.51ish load and 1.43 on lowest speedstep setting) but then again I have a crap chip and don't care if it burns out.

The real answer is: we don't know how fast 1.5v will get you. Will it get you 4Ghz? Unlikely, but if it does, I'd be very tempted to run it at that...
 
when intel says its good up to 1.5v? do they mean in the BIOS or in CPU-Z?
if CPU-z, do they mean 1.5v reading at idle? or at load?

and

should i test with Gigabyte's "performance enhance" on standard, turbo, or extreme? i never understood what these mean. LLC is on for all my OCs BTW

CPU-Z. Doesn't matter whether at idle or load. 1.5v is the max it should have in CPU-Z.

I don't know what the "performance enh" is, you'd have to read about that on your own.

Incorrect, READ THIS AND TRY AGAIN.

Software doesn't have the resolution to record proper voltages.

@Gillbot. So essentially, you use the Vcore reported in BIOS, not from software programmes, such as CPU-Z, etc, because of this:

No software monitoring can do this as the demands are beyond the sensor providing the information. Testpoints taken right off the board to the right equipment would reveal this nicely I gather. 🙂

I've always wondered why the BIOS VID was different (higher) than that shown in CPU-Z.

I've read the thread, but I'm now reading the rest of the article.

Not personal experience but a close equal. A good amount of seawater made its way into a closet and during the storm the seas were bad enough that the PC got tossed around physically destroying all the parts in the process. The CPU did survive though! :Q

I'm surprised the sea water didn't kill the CPU as well.

LGA775 packaging is much more resistant to physical damage than a PGA package. I just washed it off with RO water, let it dry and wiped down the pads with a foam applicator soaked with Caig ProGold G5 and all was well.
 
looks like i'm just going to keep it at 3.6 @ 1.4 vCore.
temps are great.

i highest i've gotten stable was 3.78 (didn't try hard after that, didn't wanna push the chip i planned to keep for 3+ years).

 
3.6 at 1.4 is good. Now just start dropping that VCORE until you get errors just to find out where the floor is.

I had a Q6600 that was running at the default VCORE setting at 9x400 and realized the DFI BIOS with VDROOP off (the programmer was dyslexic hehe) was pushing 1.4! So I dropped it and did not get errors in OCCT/Prime until I was BELOW 1.3! So I settled on 1.35 and it was a happy little chip! I even ran it this way with the stock cooler, fan unplugged and saw coretemp values well into the one hundred and teens! I have a screenshot of that somewhere...

Incredible G0's indeed!
