OCUK Sandy Bridge, SB-E and Ivy Bridge 5GHZ Club

My OEM 2600K is on it's way back for RMA. It runs perfectly on the P8P67 Pro although the voltages are higher than I would like the top clock is good. But it will not run in my P8H67 Pro which is what it was brought for... I'm presuming the Intergrated Graphics are bad.

Anyway, so i'm sat trying to decide what to do... order another OEM or wait to see if some C batch turn up - although it seems the C Batch is far from a guarantee, really just the chance of lower volts ant temps.
 
Simon here is my OEM CPU arrieved this morning. Ignore the volts that is not correct.

The OEM CPU was ordered yesterday afternoon from OCUK yes. I had a quick ten minute play with the CPU as soon as it was delivered. Nothing more than that. So no idea what the max is. Will find that out on the weekend. Just did not have time as yet.

But very surprised how good it clocked on first boot. :)
 
No batch numbers

Sorry if I missed a post, but why no batch numbers?

Is it against ockers.uk policy?

There would be too many shop requests for a particular batch?

(or is it just that different batches just don't show up as golden selections)

With SB there is no point in having batch numbers. Of the 12 CPU's in total that I have binned for both myself and others. There can be sequential following batch numbers with completely different over clocking profiles.

To illustrate. Three CPU same batch, different wafer number. Two would bench at 5.386 (54x) with very little effort. The third would not even boot into OS at 50x multi.

But as a rule most CPU's will get to 5GHz or close to it.
A few will get to 5.4GHz
And very very rare to get one going past that and able to bench with.

So you were spot on. There is no golden batches like there was for 920's. :)
 
What do you believe to be possible as far as overclocking is concerned with
the new Sandybridge chips on air or water?

I'd also be interested to know if any one has done anything in this group has done anything extreme as far as overclocking is concerned and what raw speeds you managed to achieve. E.g. blending your tower into a fridge or pumping/routing in air from your air conditioner to your tower to keep in
extra cool?

I am hoping to join this club in the near future as I am going to be doing a new build this year. I have already bought a case. I am going to buy a power supply this weekend for it so any advice on power supply I'd appreciate it. I was thinking of going with an i5 Sandy 2500k.

My present system is caput. It was an ancient AMD barton 2500 system. It had a 430w power supply but at max it only ever drew about 130w. What do you think I am likely to need for a new 2500k build? I am not a gamer btw. Will be using it for video editing though, audio, maybe a bit of flight sim and an F1 game but that's about it.

Finally, just interested to know what bugs have been reported with these new chips/mobos or any issues you've had with stability? Which mobo do you recommend? MSI? Giga? Asus?

Hopefully anything like this will be ironed out by the time I purchase the mobo and cpu etc as I usually buy certain components last. I buy in a certain order especially if I can't afford the parts all at once and am putting the system together over e.g. a few to six months to avoid depreciation on parts more likely to go down quicker in price.

Cheers,
John

Thanks for putting me straight. At last, somebody who has seen past the hype.

I am an ock/uk customer of many years, from day one I think (my join date, left, is one of many) and have just purchased my UD7 and 2600K. (Do not mention the batch number!! :eek:;)).

Now that I can see past the BS I can concentrate on membership of the 5GHz club (Or not:)).

5ghz 12 hour prime stable

Finally!!! :D

5ghz.png


I'm happy now, not gonna even attempt for a single mhz more :) (maybe)

Just for info, I was superpi 'stable' at 1.365 @ the 5ghz mark with a 50x multi, and slowly creeping the voltages up .005 at a time, I was at 1.43v in the bios and it was still dropping out - after around 6 hours

So, I dropped the multi to 49, and increased the bclk to 102.1 and its stuck. Slowly taking the voltage back down now to see if there is anything to discover when using the bclk to overclock i.e. can you use less voltage

Coming from superpi stable to this though, with the 0.005 increments I have used in the bios voltage, I have dropped out at 20mins, 45mins, 2hours, 3hours, and even 6hours.. so from what I can see (purely based on myself admittedly) being 3+ prime stable doesnt count for much
