750878	2009-02-24 20:04:00	One time, I was trying to clean the CPU and use Arctic Silver cos my new Quad Core temp is down to under 30 . I mistakenly put the CPU in wrong way and turned it on . I have bought a used Athlon 754 CPU and still no go . Before was a Sempron . Why would you mess with it if the temp was under 30? Under 30 is cool, not hot . How did you use a Quad core on a socket 754 board?	pctek (84)
750879	2009-02-24 23:06:00	It's not possible to put a socket 754 in backwards unless you use a hammer, or you cut some pins off. Not sure about LGA CPUs as never touched one but I imagine it would be easier to install the wrong way. Which I assume is what you're talking about since there are no such thing as a Quad-core CPU for socket 754 I imagine in any case, the CPU and Motherboard would be damaged and possibly the RAM. Maybe some other cards too. PSU failure sounds unlikely, any good PSU should shutdown if anything weird happens	Agent_24 (57)
750880	2009-02-25 02:28:00	I'm guessing english isn't your first language :) Sounds to me like having seen the temperatures of a new Quad Core pc you decided the old one was running hotter than it should ? Too late now, lesson learnt, but technology and normal temperatures change over time, if it was working ok there was no reason to mess with it . I'm puzzled like everyone else how you got it installed the wrong way round, unless it was the heatsink and not the cpu, as they had a recess on one side that needed to line up with a raised part on the socket in order to sit FLAT . If it was just the heatsink the motherboard should be ok and you just fried the cpu, if you somehow forced the CPU in 90 degrees out of alignment you likely dmaged the socket as well as the cpu .	dugimodo (138)
750881	2009-02-25 04:23:00	Why would you mess with it if the temp was under 30? Under 30 is cool, not hot . How did you use a Quad core on a socket 754 board? The Quad Core was doing over 70 degrees hence I applied Arctic Silver . I got it down to 30 or 25 during idle . The Sempron 754 was doing 35 degrees but I thought, hey, I have spare Arctic Silver, maybe I could get it to a lower temperature . Re: the Sempron 754 on the 754 motherboard, I have no idea, the pins are straight . Someone pointed out that they were a bit unstraight . Not sure, they look pretty straight to me . When I installed it, the OEM heat sink fan just latched on without any problems, hence I didn't notice it . Regarding the 90 degrees . Someone said to me when I took it off, that the CPU was 90 degrees away . Ie . , instead of facing north, it was facing east or west . If you get the idea . . . . . .	Nomad (952)
750882	2009-02-25 05:48:00	So you installed the CPU the wrong way on two different systems? Or the LGA775 was 90 degrees out of alignment, and the Socket754 was just not working and you don't know why? You didn't manage to pull the Socket754 CPU out while still attached on the HSF when you removed it, did you? That's a good way to ruin CPU/Socket	Agent_24 (57)
750883	2009-02-25 05:51:00	Should just scrap the 754 setup, for the price of replacements parts you could get an am2 setup thatd zoom on past it	hueybot3000 (3646)

You didn't manage to pull the Socket754 CPU out while still attached on the HSF when you removed it, did you? That's a good way to ruin CPU/Socket I didn't touch the Quad Core at all . That is fine just sitting there . The Sempron 754 was out of alighment with the 754 motherboard . The 754 CPU, well the only way to take it off was with the HSF . It was stuck on and it was buring with electric smells .	Nomad (952)
750885	2009-02-25 06:12:00	Oh I think got it now... sorry You put AS5 on your Quad and brought the temperature down. Then decided to do the same with the Skt754. However after doing so, it didn't work and smelled of burning because you reattached it incorrectly? My question is, then, when removing the Sempron to clean off the original AMD thermal interface material, did the CPU stay stuck to the HSF and get ripped out of the socket? Or did this only happen the second time? or did it happen both times? In either case, you need to twist heatsinks sideways first (after undoing any clips) to break the seal before removing them, so as not to pull out the CPU as well and damage anything.	Agent_24 (57)
750886	2009-02-25 09:09:00	Initially the HSF dislogdged easily off the CPU b/c I didn't use additional thermal paste. It was jsut the adhesive factory OEM thermal paste off the HSF. Which in the past I had taken it off for some work so the paste was quite weak. Bit like weak cellotape kinda thing. Only the last time with Arctic Silver did I drag it out, cos it was stuck on. Once the HSF and CPU was off (together), the Arctic Silver was not totally hard yet, I had to slide the CPU off the HSF to separate it. It was smoking and smelling. You could see smoke.	Nomad (952)
750887	2009-02-25 12:19:00	Maybe it is easy to install a Socket 754 in the wrong way: Unfortunately, S754 doesn't "float" on top of the socket as well as other sockets . There are only two pins on a corner that would be keeping it up . This means that you can install it around the wrong way, and the chip will somewhat drop into the socket, but not be sitting flat . These two pins are relatively easily bendable in the process, or failing that, the installation of the heatsink will provide the necessary force . Other sockets tend to have more - and more spread out - key pins so that virtually none of the CPU will go into the socket (it will "float" on top) . Anyway, since you tried a new CPU and there still was nothing, I expect the board was also damaged . Not surprising if there was smoke coming off the CPU . . . Trademe has some Socket 754 boards from $50 - $90	Agent_24 (57)
