Lynnfield finally launches

Well, have you heard of any great stock fans before? xD

Drew:
If you're buying a new CPU within a month of its launch, chances are you're an enthusiast and you'll be buying some sort of third-party cooling apparatus as well.

It seems there are some issues with pin contact between the processor and socket. It won’t affect most people, just the extreme overclockers. Also interesting to note:


--- Quote ---a quick glance at Intel’s white papers for socket 1156 CPU’s reveals that there are around 175 pads for VCC compared to over 250 for socket 1366 CPU’s. This means socket 1156 has around 66% of the current capacity of socket 1366, the caveat being that when overclocked, processors from both platforms draw similar levels of current.
[...] The facts point toward tighter current handling tolerances for socket 1156 when compared to socket 1366, especially when it comes to non-connection of VCC/VSS power delivery pins.

Lesson: If you plan to try heavy overclocking, go for a socket-1366/i7-9XX setup rather than Lynnfield.

Do read the article before replying; it covers some things that I conveniently left out while trotting this out during a short lunch break.

What would be a good price/quality motherboard for an i5 for up to $200 ? I'm not interested in SLI or Crossfire , just  decent build quality and light overclocking, up to 3GHz. Also, do you think a after-market cooler is needed for this kind of overclock, and if so, could you recommend one?

K7IA:
This is a serious design fault on Intel's part imo. The previous design allowed pins to be compressed from both sides (left-right) which allowed better (and may be more) contact surface and a good tolarance for grabbing cpu pins, just like in a conventional 220V power socket.

This was is a conductance design disaster :) . I mean you don't have to overclock it to burn your cpu, due to dust, humidity the resistance will increase between the couplings, resulting in a poor electric transmission.


--- Quote ---We draw your attention to the fact that the processor shown in this pictures exhibits signs of insufficient pin-to-pad contact (little to no contact) in what is a rather reproducible pattern with Foxconn manufactured 1156 sockets

yay!

But it has not moving parts, as far as I can see which means lower production costs and might allow lower design profile.



--- Quote ---At first glance, one might be inclined to think LGA-1156 based processors are intolerant of high-end overclocking, almost as if by design.

What makes us think that Intel will not use this for future designs?

I am not an overclock enthusiasts, but I must say, I see the LGA-1156 pin-pad design now, any electronics guy can realize that there will be a problem once the cpu starts acquiring more current.

ps. it says the CPU uses the 12V line  ::)

[edit] the overclocking dudes could use a thin plastic sheet, put in between the socket and the cpu to test the degree of contact between them before attempting to overclock.
