That chip's watercooled. 44C on cores means a main CPU temp of no more than 35. At 1.42V, it wouldn't idle at 35, let alone run like that under load.

sam,
It's also not going to last too long at that voltage either. Even being water cooled, Electro-Migration has already started! While heat does hasten the process, the primary issue is totally electronic, and mathematically predictable! All water cooling can do is slow down the process. LN2 will slow it even more. Error correction in the CPU itself will handle it for now, but eventually the errors will become greater than the ECC can handle, and that's where it gets real interesting, because you'll have no idea from one day to the next, what the hell is wrong with your computer. One day you'll think it's the memory because it fails Memtest with thousands of errors. Yet checking the same memory in another computer yields no errors at all! With my E6750, I knew it was hurt, shortly after I bumped the voltage to 1.576 to get to 4GHz when I first got it, because it never came close to that speed again. It wouldn't do a lick over 3.55GHz after that and be completely stable, and I kept having to add a little voltage every 4-6 weeks to keep it stable. When I ran out of adjustment for the voltage, it just went nuts. I had lock-ups, some requiring the PSU to be shut down to turn the computer off, system re-boots, and File corruption errors on a CD (impossible to have)! It also started to corrupt files all over my hard drives. If I hadn't had backups of all my software, I would have lost about 1/3 of what I own. I had about 150 or more programs stored in my Software folder, and the ones that were corrupted, were trashed! It took me about 2 weeks to figure out that the problem was the CPU. I finally put my spare, brand new D-940 in it and overclocked it to 3.7GHz and all the problems vanished! I had the replacement E6750 Intel sent me up to 3.8GHz with a much lower voltage than it took my hurt one to get to 3.55GHz. Of course I could have lived without those couple of weeks I spent tearing my hair out trying to figure out what was wrong with the damn thing! LOL!!
I might have been the first here on AD to realize what my problem was, but I think Rob was the first to experience Electro Migration with his E8400. In fact, his experience with the things that were happening to his computer, is what finally convinced me to RMA the CPU. If you remember he changed pretty much everything with that build, until there was nothing left but the CPU, and when he changed that all the problems vanished. The most maddening part of the experience is you would short the CMOS and set it all up, and it would run beautiful for a day, day and a half and then wouldn't boot up the next time you turned it on, until finally it wouldn't boot the computer because of a corrupt config file error. If you tried to boot from a floppy or CD, it would pop up the no NTDLR (or something like that) was missing. Time for Killdisk II! LOL!!
That Q9650 will fail! It's not a question of if, it's simply a question of when! Whether it will be covered by warranty or not is a good question. I know that on the higher end CPUs, they do look more closely, and they can tell if it's been run past maximum volts (1.3625v for the Q6750) and determine if the problem is caused by Electro Migration. I have a Dentist friend of mine with a SkullTrail platform, socket 771, and he didn't realize that the voltage wasn't the same for the QX9775 as the socket 775 QX9770 and fried the CPU. The QX9775 has no voltage range, just one voltage, 1.212v! If you exceed it and it blows, Intel will not replace it! You will have to buy a new one! With LN2, Dr Lee had his clocked to just a hair over 6.0GHz at a shade above 1.9v when it quit. It just stopped, never to run again! I personally saw it run at 5.7GHz on LN2! You just got to be nuts, if you ask me! LOL!!

Russ

I use that voltage with my Core 2 Quad. 1.4 to 1.425V is what I've used a lot. I have had it higher than that as well temporarily.
I'm well aware of the issue with electronmigration. 175mV is the gnerally regarded 'upper limit', it isn't usually a breach of the safety zone. If I was using 1.5V, I'd be worried.
Additionally, the 'no voltage range' QX9775 CPUs in Zardon's system at Driverheaven have been running since summer 08 at 1.4V with no issues.

So I have been trying to overclock this processor with no great success:
So far:
400 x 8 = 3200mhz (unstable)
333 x 9 = 2999mhz (stable)
400 x 9 = 3600mhz (unstable)
378 x 9 = 3400mhz (unstable)
with the following settings, can anyone tell me what to do in order to get that 400 x 9 = 3600 stable???

The OCZ memory might be your problem, depending on what speed it is.
I can only assume CPU voltage is Vcore special add, in which case you need to raise it above auto to break free of 3Ghz.

well the cpu vid control is the actual thing that changes the voltage...
even if i set the voltage to 1.45v, i still get 3ghz as the absolute maximum
and the ram is running on a divider of 1:2 so its not going over spec which is pc6400 (800mhz)
maybe my cpu is just a bad overclocker?

The VID is not what should set the voltage. That should be the identifier for what voltage the chip would normally use when stock.

i know what the VID is, but that option does indeed change the voltage...

you were ABSOLUTELY correct sam!
i wad being retarded
thanks for the solution bud!
right now i am at 378 x 9 = 3400mhz but again, it is not stable....
even with 1.4v on the core

1.4 is on the low side. Go for 1.45, that's what I used to get my chip to 3.2.

what cpu do you have? q6600? if it was, what voltage did it take to get to 3.0ghz?
and if its not too much trouble, could you tell me what batch code your cpu is?

I had an E4300, can't remember the batch code, it's currently installed in a system. Would CPUZ tell me? I used 1.45V to get 3.15-3.20Ghz. I used 1.425V to get 3Ghz, but it wasn't very scientific, I tried it and it worked (1.425V) - 1.45V was actually an Autoset.

Sam,
A screen shot of your screen should show it. The picture you get if you do the authentication doesn't show the voltage as far as I know.

Sounds about right, your higher end board will probably have less vdroop than my old P35 did back then.

1.36V is barely any higher than stock. You could almost certainly go significantly higher with 1.45V.

Well, you're using a lower voltage than I did to reach that speed, but my chip was clocked slightly lower to start with, so it's hard to say. (The E4300 is 1.80Ghz, not 1.866)

actually the stock speed is 2.66, not 1.866..........
and its a quad...
stable now at 1.424v speed = 3400mhz
edit:
not stable

I lol'ed. I had you confused with the guy running an E6300.
I owned a Q6600 as well as the E4300, which I have since sold, but I ran that at 1.45V to reach 3.24Ghz. That started at 2.400Ghz. It was the weaker L8 revision. I could get it to about 3.42Ghz with 1.5V, but 24/7 stability wasn't great as I had all four memory slots populated. Since I wanted 4GB of RAM more than I wanted extra mhz, that's how I left it.

lol, i am the same guy....
but the e6300 is absolutely stable at 3400mhz, now i am trying to get the same speed with the Q6700
Q6700 not stable at 3400 mhz with 1.424v
i think i am gonna leave it at 3200mhz, what say you?

Now why would you do that to a man! No wonder I got confused. I had no idea you'd stabilised the E6300. The Q6700 will probably take a similar voltage to reach the same speeds. Quads don't overclock as well as the duals.
