Bloomfield 'best cherry chip' by rjk

bulldog147 · 17 May 2012 at 21:43

I had set up an overclocked bundle 4.20GHz with a cherry picked by rjk back in 2008 (even a crazy cherry chip was clocked 4.20GHz at just 1.264v on full load)

It been stable over 35 hours and was stable over the years with no BSD. The bundle I had set up with the corsair memory ram (triple channels) and mega air cooler with temp of no more than 75C.

Vcore set at the bios 1.325v
Idle at windows 1.296v
Full load prime95 1.264v

Many thanks to rjk for excellent cherry chip and I did push it to 4.5GHz at 1.35v under load. Will be excellent with custom water cooling as it might do 4.7GHz possible.

Wow that's amazing. Do you mind sharing your BIOS settings?

I'm on an i7 920 too. 4.2GHz at 1.39v... watercooled. It's ridiculous how hard this chip is to overclock. I have the same stepping and revision as you, so I'm very interested how you achieved this OC!

Saul, Many thanks but unfortunately not every chip can do the same as my chip as my chip is ridiculous crazy low voltage! It was picked cherry chip by ocuk guy rjk in 2008. I will never sold this cpu chip ever. Doing so well over 4 years now.

I got other sandybridge also overclocked 5GHz at 1.38v under load. See below:

It would be very hard to get 4.7GHz as you'll need a BCLK of 220MHz+ which is highly dependent on how good your motherboard is.

Yeah very true indeed! Need a very good top of the range motherboard but it no point to buy it as long it was fine up to 4.5GHz

Most i ever managed on mine.

Vcore in bios of 1.3125, load iirc was 1.296 or thereabouts. Cooling at the time was a supermega.

Nice one setter

Ceptic · 18 May 2012 at 01:29

Sat at 4.2Ghz 950 under water @1.3v, doing it's job fine and keeping cool, upgrading fans and will hopefully try get 4.6 stable

looks like I may also have a nice chip

wazza300 · 18 May 2012 at 01:48

nearly as good as my chip in my sig

that's pretty good gold chip u had there

wazza300 · 18 May 2012 at 01:53

whats the batch numbers? ill dig my box out and post it,bought mine on launch from the u.s in 09

are you clocked through dvid bulldog? power saving enabled? i am,youll lose a lot of temp at idle if you use dvid

bulldog147 · 18 May 2012 at 01:55

I throw away the retail box but the batch number is here on the forum 4 years ago! Can't be bother to search it. lol

PaulyD · 18 May 2012 at 09:20

my 920 was 4.2ghz @ 1.288v as well with 12gb RAM, 12gb never seemed to hinder the OC

setter · 18 May 2012 at 18:20

Btch no of mine is.

3927A336

Bought from ocuk almost three years ago.

OLDPHART · 18 May 2012 at 19:13

hi, same as setter but not sure what the batch No is and theres still plenty of life in the 920 yet, cracking CPU.

setter · 18 May 2012 at 19:17

I think it'll be a cpu like the q6600, those things were bomb proof. Ran mine at 3.8ghz for a year 24/7. As far as i know it's still going strong.

bulldog147 · 18 May 2012 at 20:02

Yeah 45nm is quite strong chip but I do feel ivybridge 22nm won't last forever (probably less than 3 years due to heat problem) Bloomfield and q6600 are very good cpu, quite strong! I sold my q6600 to my friend Tim, and he still using it, I think q6600 is probably 8 years old now whille my bloomfield i7 920 D0 is 4 years old except my sandybridge is less than 12 months at the moment.

I started buying Q6600s in 2007, its about 5yrs old, bought my first batch of 920s in very late 08 to early 09 so its not quite 4 years yet as i tend to buy within a week or two of launch as i get a few orders in pre launch, sometimes when something is big (core 2 duo for example) i'll get my mitts on an ES and mess about before launch.
