ummm I was worried the OEM's might be older... Intel often produce the OEM chips first and retail afterwards at launch so that they can supply the likes of Dell and HP quickly.
OCUK Sandy Bridge, SB-E and Ivy Bridge 5GHZ Club
- Thread starter SimonMaltby
- Start date
They don't need to hand pick.. the bundles are well within what all the Sandy Bridge chips seem to do without breaking a sweat. 4.4 and 4.6 are nice overclocks and will keep things nice and cool, but they are not a challenge.

Old chips r no all bad my L040B307 Does 5Ghz 1.345 maybe lower still got to try!
I don't consider L040 as old... my 5.4Ghz is an L040 (I assume that is the week of build?) It all seems to be a lottery tbh
Right, done some work so I think I'll see what it can do for abit
Just done over 3 hours worth of ray trace rendering though at 4.8ghz, without a hiccup, and that was at 1.35v in the bios. No prime testing yet though
Do these run any hotter with the hyperthreading enabled?
Loving the hyper threading by the way. An 8:51 render using my 2500k at 4.8ghz is now done in 6:20

It is when there L053 and 54 and Cbatches! Knocking around!

I am looking for those with C in the batch number.
Sorry I recalled rjkoneill's post wrong, remembered him saying "most of them just stop at 4.4" when he actually said "some of them just stop at 4.4".

As a rule OEM CPU's are no different from full retail. The CPU's are mass produced and packed as the order book dictates. There is no plan at all. Yes it is true that OEM system builders often get first bite of the cherry that does not mean the CPU are better or worse. BUT SB has turned the whole CPU world up side down so why should what has gone before mean anything in this instance. Nothing else with this CPU has.
I'm impressed
Its a bit late for fine tuning, so I went the other way and have just ran superpi at 5.0ghz with 1.35v
My aim is for a 5ghz stable 24/7 with hyperthreading on, so this has potential
Whats the lowest voltage for 5.0ghz that any of you have seen?

1.32vcore is the lowest i have seen for 5Ghz!
My OEM 2600K is L038A653 2179
So probably not going to be brilliant.
Anyway, it's in the machine and I'm just bedding it in

Well I take it back.... although the voltage is way too high for my liking at 1.55v runs super-pi 1M at 5.5GHz 100x55
