anyone running 5GHz 24/7 on their SB system?

Also is the Asus p8p67 deluxe board good? Been reading a lot of people on here putting them down? :/

I've had no problems at all but I still have the faulty batch and I am waiting to hear back about B3 replacement which I read is poor. :( Don't know whether to get a refund and replace with another
 
no the cpus are picked from batch numbers, then i overclock them gradually from a 'standard clock' say 4.6ghz
and if it bombs out at say 4.8
then i move onto another cpu. when you get one that goes high on safe volts then i try it on max safe volts and see what it pushes to. if it has a bit more left in it. then it gets put aside for our systems with big overclocks.

or in this case, i buy it and push it to is max limit

@1Day. yes. the cpus are good. i need a bit more time on the 2600. i might actually buy them both and see which i prefer in real terms. then sell the one i decide not to keep as a proven clocker.
 
the deluxe is ok, but no better than the pro.

in fact i would say that all the asus boards over the pro are only worth it if you NEED the extra features that the boards offer.

i have benched on a maximus and it was NO different overclocking wise to the pro.

i could spend that extra cash on an elmcrest ;)

I more directed the question towards 1day but thats cool to know :)

Working at OcUK is like a dream job!

it certainly has its perks :)

no worries, at least you know that if you were to buy a custom system with max oc that you would get an uber cherry picked chip.
 
Will I get a
"rjkoneill chose this CPU for you
Love the OcUK team"

Card with it ? :D

I'd love to visit your shop one day but living down south makes it kinda hard :(

Also what can I actually do about getting a B3 Asus board?
 
the shop is nothing special, typical computer shop affair.
we have a state of the art technical area with all the testing equipment we could ever need hidden away. its best they dont let me out much :D

b3 boards, you just buy one with the b3 revision marker on the listing.

if you have an older one and need it swapping out for b3
post here

and i will sort it out for you :)
 
Yeah I meant as a replacement for my older one.

And you star! I just want to pop in and chat. Around my area there is no computer shop as near a standard as OcUK and the team sound the nuts!

You just bin them if they're not good enough? :(

:eek: No - binning refers to placing the different CPU's into an appropriate bin. Hence the term binning. So there is a 5.7GHz + bin, a 5.6GHz bin, 5.5GHz bin and so on.

Those that do not make the grade less than 5.3GHz bench-able are put to one side and either built into systems that are going to be run at stock or with a very low level of over-clocking. Say 4.4GHz. Not all my mates want heavily over clocked systems. Only the gamers among them do.:p

@ rjkoneill - Any time you find a golden CPU that you will not keep for yourself 58X or better or 109BCLK @54x you give me a call please. :D:D
 
I'm running my 2600k @ 5Ghz 24x7, my config is:

Intel 2600k OEM @ 1.4v
2x 4GB Geil DDR3 1600 RAM
Antec Kúhler H2O 620
Asus P8P67 PRO

You know in all the benching I have done, I have never killed a CPU yet. Not under LN2 and not even running a 980X at 2.1 volts. :D:D

Not one CPU.

Ram yes - I have killed plenty ram.

off topic slightly:

1day....what did you get that 980x up to with those kind of volts (2.1 :eek:)

i would love to get to the end of the month and buy 11 cpus with my wages....theres not many things id rather do than bench 11 x 2600k to see what the golden chip amongst is......its like collecting panini stickers when you were young and finding a great player or a shiny badge in a packet....i can imagine how charlie bucket felt also

mmmm...i would say thats rjk's perk of the job and spie wouldnt approve.
dont mean to talk out of turn but thats the way im seeing it...maybe im wrong

cammy5477 I suspect you are right but heck it does no harm to ask. :)

The 980X was a real dog of a CPU. My other one would go to 6.4GHz with 1.825 Volts and this POS would not get past 5.9 regardless. So I tried way tooooooo much voltage in the hope that it would suddenly scale. But nothing. So it was relegated to a build I did for a bloke who does animation rendering. He got a really good deal on a CPU that cost me far to much. Thems the chances you have to take when you bench.

bet you didnt buy 11 of those mate.....:D;)
 
Nah - 2 in total over a six months span. I had to pay for new motherboards too if I recall that sad and sorry time when they were released. :p

After the second one I just gave it up as a bad job. There was no way I could afford to bin those pricey little toys for a 7GHz chip. Think there are five of them world wide that I know of. :D Well not on my salary anyway.

One bencher that I know went through 144 CPU's to find one really good one. :eek::eek: But he is seriously rich and can afford to.
 
There is a whole heap of people who have 5GHz + over-clocks LINX stable it seems.

(Update: 3 Jan, 2011) Sandy Bridge owners - please only post 5GHz+ submissions. I am keen on preserving the challenge, so I will only add SB to the 5GHz club. Thank you for understanding.
[*]Screenshot must show a LinX window (max memory settings, click "All" button or pick the last memory size option from the drop down menu, the "All" option is highly recommended) either running the 20th+ loop with no errors, or with 20+ successful passes.
(Update: 14 Dec, 2010) Please make sure that LinX is running / calculating (21st or higher number loop) when you're taking your screenshot (on at least one of your screenshots). You obviously want a CPU-Z window with 4.5GHz+ (5GHz+ for Sandy Bridge) frequency on the same screenshot, as well.
This rule will be enforced for all the new submissions.
Friendly reminder: use all the memory you've got. You don't need more than 1GB of memory for OS and applications. Enable Page File. Do a short LinX run to free up some RAM. I don't want to see 2GB LinX runs with 4GB of RAM installed any more.
Click here to download the latest version of LinX with updated Linpack libraries
[*]List the motherboard you used.
[*]List the cooling you used (cooling type at least, such as: air / chilled air / water / chilled water / phase).
[*]List your full batch number (highly recommended, but not a must).
[*]Optionally, you could show us your voltages using a program coming with your motherboard, such as EasyTune, E-Leet, TurboV, etc.

(Update: 19 Feb, 2011) Concerning the AVX issue for Sandy Bridge:
According to the tests I've seen, Sandy Bridge at 5GHz+ frequency is able to output 100+ GFlops with AVX enabled with little effort.
To make sure that you have AVX used you need to do the following:
  1. install Windows 7 Service Pack 1;
  2. download and use the latest version of LinX (you can find the link above);
  3. either disable HT or tell LinX to run on 4 threads (for 4 core chips, etc.) if you have HT enabled (current Linpack is poorly optimized for Sandy Bridge [only] chips; telling it to run on 4 threads doesn't just improve performance but also slightly increases stress levels).
Using AVX enabled LinX increases stress levels. To separate those using AVX from the rest, I am going to divide 5GHz Club into 2 categories: "Over 100 GFlops" and "Under 100 GFlops". This seems to be the only way of determining whether someone uses AVX or not for sure.
To make sure you get into "Over 100 GFlops" category, make sure that at least one of your loops has 100+ GFlops performance. Obviously, it has to be visible on the screenshot of your submission.


Also, please do not post images wider than 1280 pixels, use thumbnails / links if you have to. I strongly recommend cropping images instead of scaling them (stick to 100% scale). Thank you! :up:

Simply amazing what they have managed :eek::eek:
 
I have found Lynx and IBT to be totally useless for testing stability on these chips. I can do hours of Lynx at 1.37 @ 4.8 but Prime Blend fails after a couple of minutes. I have also found the relationship between VTT and VCORE is very important. Just a couple of notches can make the differences between stability and failure.

Anyways, here's mine @ 4.8 on relatively sane volts.

This is the latest UD4 beta bios.

NB: Not sure what's up with my AIDA64 GPU clocks - seems to be reading them wrong.
