Hats off to you sir, I lol'd.

Destroying a chip just to get an epeen screenshot is really beyond me understanding. Almost 1.7v is not going to make that SB feel nice inside. I'd be surprised if it lasts long at that speed/voltage while benching if the rumours about extreme degradation are true.

if you take a moment and look on hwbot.com you can see that 1day holds nr 40 in the WORLD. you can not reach this faime among oc with stock speeds. Like any extreme thing, extreme oc is not for evrybody.
well done 1day

Is it weird to be impressed by having an N2 dewar in a garden? Do Cryoservice turn up every month to top it up...

Have you ever considered He cooling?

1Day · 3 Feb 2011 at 18:59

HE cooling is a very real option. It is available to me but the price is insane. So as a option that has been laughed off. HE has been benched by a number of people elsewhere. I think the price and health and safety issues are insurmountable here in the UK.

I think this is really impressive and interesting about you're findings of maximum clocks acheivable on each them - having one golden cpu

Out of interest, are you able to list you're 2600k's, max clock and batch number of each?

Sure here you go.

How much is it for a full dewar of N2 like you have in the picture? (i'm guessing you only borrow the dewar) Surprised it doesn't hold more than 120 litres.

Did you have to go through a lot of paperwork to be allowed to use it?

No title just forum member same as you mate. Lets leave the titles to the PR people who have to sell the stuff we buy.

24/7 overclock for these CPU's right at the upper limit of daily use. I would say 4.5 to 4.8 on water is a good limit. The SB is very good on water. The H50 or H70 will drop your temps by 15'c. The big thing is to get your fine tuning right. So the balance between enough volts to keep your system stable and not too much so that your system is too hot. Big one to pay attention to is the CPU PLL - that can be undervolted by quite a bit and reduces the heat load considerably. Also bare in mind that no two CPU's are the same or will perform the same. You have to take the time and effort to work out what is the best combination for your CPU and cooling solution.

None of the over-clockers and bencher s I know will be using their SB CPU's in a 24/7 system. So can not help you there. Most of the time we use hardware that is so no longer needed to bench with. The good stuff we bench with.

That being said I have bought a SB 2300 CPU and a H67MA motherboard for the family system. And so far I am very impressed with it. It doubles up as our media centre too. So the built in graphics of the new SB CPU is more than enough for watching our HD or Bluray media on the family telly and the bit of on line gaming my kids are into.

LOL. Coolest mom ever. Imagine that, your mom overclocking for you hahaha. IT blows my mind how different we all can live sometimes!

You will be surprised by how many people (benchers that is) do own their own Dewar. And the dewar in question is privately owned and not rented.

Renting a Dewar would push the price of the the LN2 out of my budget's reach. As it is I have to plan well to manage. The price of LN2 varies from person to person who buys it. Basically it is to do with how much you use and over what period. The 120l dewar costs me just over £140 to fill each time.

There is a fair bit of paperwork involved if you are not in an industry that uses LN2 or if you are a first time user. I certainly would not suggest to anyone that they pop down to the local supplier and fill up a bucket of the stuff. It is a very dangerous substance, and if you have a accident you can end up very dead. Perma-dead as my kids call it. But like all things if you are sensible and follow the correct procedures it is all good. In all the time I have worked with and used LN2 I have not deviated from the safe way of handling the substance. And I have no intention of every being a cowboy with the stuff.

@CmdrTobs I actually would be surprised if my kids thought I was cool. To them I am just Mom. She who makes them clean up their rooms, and do home work, shouts at them when the music is to loud, and do more homework. You know what I mean. Just normal Mom type stuff.

Hi IDay

You tested all these chips? :eek:

What do you do with them after you're done testing? I'd be very interested in a stable air cooled 5GHz chips and a recommendation for the best memory to go with it.

Your sensors are almost certainly wrong. There's no way that ambient + delta = 15.

pingu666 · 4 Feb 2011 at 18:57

nice

how long does 120litres last roughly?

1Day · 4 Feb 2011 at 19:43

It all depends on what is being benched. Some CPU's are hotter than others, and therefore need more LN2 to cool them and to hold them at the right temps. 980X being the hottest of the lot. Plus if you are doing 3D benching then you are cooling graphic cards too. That all adds up. But normally about three weekends of dedicated benching. If things are quite then the LN2 can last over a month. It is a pressurised container.

Baldbloke · 5 Feb 2011 at 13:24

Thank you 1Day for a very interesting perspective to overclocking. I hope you keep posting and letting us know your progress. I bet that is an absorbing hobby. (not to mention - expensive).

Oh I would worry more if you live near Gatwick and Crawley. 30 000 litre LN2 tank alert :eek:

LN2 is used in many industries, far more than most people realise. And is very safe in a well ventilated area. Search youtube for some of the stupid stuff students have done with LN2 and swimming pools. Not my idea of fun but it does take all sorts.

Even though me and PCs go back to 1988 and I was one of the first people through Overclockers doors, I have never shown an interest in overclocking because I couldn't see the point.
You are the first person ever to make me realise the 'point' and total respect which certainly put a few posters in their place.
