Missing cores

    Hey lads,

    Came home today to play some wow and i noticed the pc had hanged, So i rebooted and noticed the pc was hanging after it posted. So i ent right to the bios to check my voltages as i was trying to hit 3.8ghz last night. While in there i noticed in the cpu tab that cores 2 and 3 were disabled and was unable to enable them. So first thing was to reset the cmos to see if that worked. But no luck. When booting it shows the cpu as a Q6600 @ clockspeed 2cpu(s)

    Is it possible for two cores to blow ? Surely the cpu should stop completly. There isnt even an error core on the bios.

    Any ideas ? Im not too worried if it is gone, as ill pick up a q9450. But would be nice to get this one working.

    Intel 6600's are made of two interconnected dies with two cores on each, so it's possible to lose one of the dies and thus two cores.

    Next step is to try the CPU in another board and another CPU in your board.

    can you boot into Vista? Have a look under task manager to see if its picking up more than 2 cores.

    More than likely i'd say one of the dies in the CPU has blown and the mobo is simply picking them up as disabled now.

    Nah cant get into windows, even in safe mode. It just hags after post and verifying DMI pool. No error code on the mobos little screen either.

    I'd be just a tad concerned at this point that a decent bit if quad core is now fried.

    OKay Small update, Have taken the E6600 out of my media server ( which 100% works ) and put it on the 780i, but the thing wont boot at all. Turns on, all fans start up And the code on the boards lcd is " FF " which means it should boot..... But its not. I have reset the cmos jumper, tried with 2gb ram in slot 1, and just 1 graphics card.

    Anyone have any ideas ?

    Curious. How did the Q6600 far in the media server? Maybe it's possible that something blew on the board instead.

    maybe its the northbridge or southbridge but that wouldn't explain why its duo in the bios, were they being passively or actively cooled? the 780 southbridge runs quite toasty

    Your kinda stuck with a nvidia chipset mobo with your 3x 8800gtx's. 790i just adds ddr3 support to the 780i.


    BTW, there is an interesting situation developing ATM, Intel have been refusing Nvidia a licence to produce chipsets for their chips, .........consequence of this being no more nvidia motherboards, the 790i could be the last one, ..............which leads to no more Sli as Nvidia wont allow it on any other chipset but theirs.

    Intel are holding out and won't budge on this and serves Nvidia right for their own business tactics. It could eventually lead to Nvidia having no choice but to allow Sli on other chipsets in order to allow Sli to continue as a technology.

    Would be great for consumers, Sli on an Intel chipset motherboard. ATM this is only blocked at driver level.
