CPU chip rocks back and forth in socket. Cause for concern???
Hello All,
I'm putting together a P4 Celeron (socket 478) system and have just installed the CPU into its socket. The problem is that it kind of rocks/seesaws/wiggles across one of its diagonal axes (by a tiny amount). I tried to push in as firmly as I could without applying excessive force, but I couldn't get it to be completely steady. I don't know if it's the chip, the socket, or perhaps some of the pin lengths that are uneven, but when I lock the ZIF lever in place, it doesn't wiggle any more. Should this be cause for concern? How will I know if some of the pins aren't making good electrical contact with the socket? Will the PC just fail to boot if the CPU isn't seated properly and one or more of the pins isn't making contact? Or will the problem show up as subtle CPU errors or program bugs? Any input will be appreciated. |

I suppose that's why the lever *must* be locked down before you can use the CPU? :PpPpp -- L.Angel: I'm looking for web design work.

The ZIF lever gives the CPU a bit of room to move so that you can put chips in and take them out easily. When you lock the lever in place, it doesn't move any more.

If a CPU is improperly seated it usually won't boot at all. ------------- Tony Hill hilla underscore 20 at yahoo dot ca |

HAHAHAHAHAHAHAHA, LMFAO!!!!!!!!!
sorry, but i laughed *s******s* but this is the most over-protective, scaredy-cat post i've ever seen. simple question, what does ZIF stand for? could it be "Zero Insertion Force", by any chance? where you just slap the processor in there, and yes, it does rock about a bit, as most do - restricting the use of a sledge-hammer and some super-glue for the *incredibly* stupid. if your wondering *why* it rocks about, your better off asking "why DOESN'T the prcoessor rock about, when the lever is down??" - try to use logic to understand i'm sorry mate, i'm not sure if your a) very, very stupid or b) a computer hardware virgin "Prick" wrote in message .net...

I have installed two other CPU's but both of them didn't wiggle even when the ZIF lever wasn't locked in place. That's why I was a bit concerned. i'm sorry mate, i'm not sure if your a) very, very stupid or b) a computer hardware virgin As for being very, very stupid, well, it takes one to know one. At the very least, I know when to use "you're" (meaning "you are") and "your," (which is the possessive form for "you"). You, on the other hand, evidently don't seem to know the difference. Before you go calling other people stupid, I suggest you go back and brush up on your third grade English grammar. HA HA HA HA HA HA HA, LMAO. Patrick "Prick" wrote in message .net...

I have installed two other CPU's but both of them didn't wiggle even when the ZIF lever wasn't locked in place. That's why I was a bit concerned. Actually your concern is justified. Normally the CPUs lie flat on the opened ZIF-socket and do not "wiggle". You can move them sideways a bit. I recently installed several cpus where the temperature-sensor pushed them up. They had to be pushed down while closing the ZIF-socket. Other possible explanation is some object between CPU and socket (-remove), a bent pin (Bad. Can sometimes be just bent back, but may also break) and a mainboard/ socket that is not quite flat (not really a problem). Definitely not something to just ignore.

The problem is that it kind of rocks/seesaws/wiggles across one of its diagonal axes (by a tiny amount). Naturally. A ZIF socket is really very loose when open. Otherwise it wouldn't be zero. It is only tight when locked down. The way it works is that it really isn't a socket at all. The top is a comb (template) to position pins. The bottom is a series of carefully designed open sockets that make electrical contact with the sides of the pins. Also arranged in a precise grid. When you lock the lever down, the top comb shoves the pins sideways into the sockets. -- Robert |
