Intel Core 2 Extreme X6800 Black Screen!

[HarleyS79]

Hi All. Thanks for any help in advance.

I am having an issue with this X6800 CPU. I work a lot on computers and i am confident that my rig is up to par with this CPU,
so there may be an issue with the processor being DOA. I have exhausted all possible reason as to why i am getting a black screen on boot.

My specs are:
yes i know sucky parts mixed with new to newish parts ;p

elite group 945gct-m3
Link to specs http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?CategoryID=1&DetailID=719&DetailName=Feature&MenuID=1&LanID=0

Nvidia Geforce GTX 560 ti
2x 1gb Samsung ram,
3 hdds, DVD drive,
sound blaster card
my psu is Tunia 650 watt and i know it's up to the job.

My system is very clean. I also have double checked all connections. My bios is the latest. There is no grounding going on in there. when i put my Intel Pentium D back in it boots just fine! but when i put the x6800 it boots for 2 seconds then turns off then on then sits there. fans are running good, my thermal compound is the best. My system has always run fine, I just don't get, Please help....

Your motherboard does not say it supports the extreme core 2's.

Because the X6800 isn't compatible with the 945GC chipset:

http://ark.intel.com/products/chipsets/28994

Look under compatible products on the left hand side under specifications. It only supports up to Core2Duo E4700 (with 800MHz FSB). That's why you get no boot with it, but do with the P4D.

FSB 1066
Supports the latest 1066MHz front side bus Intel processors

Core 2 Duo
The processor is manufactured on Intel's 65nm fab process, regardless of L2 cache size, resides in an LGA775-style socket and runs up to 1333MHz front-side bus. Its power consumption is really much lower than previous Intel desktop chips.

I am not sure why you guys say it's incompatible, The website clearly says it is

sighs..Man i hope i didn't buy somthing that doesn't go to it.

Click CPU/ top of the list.

I used this list to buy the last CPU for it...

I'm going by what Intel says, and they say that series CPU isn't compatible with that chipset (there are 5 or 6 'versions' of the 945 chipset, each with different compatibilities). It's a bummer I know. I had an old Abit board that would take any P4 (D) or Celeron, but wouldn't touch Core2Duos even with the latest BIOS.

Here's the X6800 compatibilities, lists 6 different 945 chipsets, but not the GC:

[scottiemedic]

The FSB on the 945GC chipset is 533/800 according to Intel, so how can ECS think a 1066 FSB will work? I think ECS got some charts backwards online.

GOT IT, click on Specifications on the ECS website and scroll to the bottom:



Remark

º Only A2 chipset supports FSB1066 MHz, and Memory DDR2 667

There's the kicker. Have to have the right version of the board.

 

[HarleyS79]

so um do you guys think i am safe to keep it, and buy a new mobo?

This is where i got it, http://www.ebay.com/itm/320853483769?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2648

Thanks all for your help

 

[scottiemedic]

I think it's a safe bet to keep it and get a different board. Just make sure to check ark.intel.com and look up the mobo's chipset compatibility before you pull the trigger, or look for the V3.0 of the ECS board you have.

More info from ECS:

http://www.ecs.com.tw/ECSWebSite/ECSSearch.aspx?menuid=0&lanid=0&keyword=945GCT

Looks like 4 versions of the same 945GCT-M series.

So A2 not the M3...Gahhh lol

I made sure that my board is the

945GCT-M3 (V3.0) sighs again...

Looks like you either have to resell or buy a new mobo...

It's all very confusing, I checked all the links, and each of them say they 'can upgrade to 1066FSB' but none list BIOS downloads for CPU compatibility, and the chipset limits to 800, not like you can download a gremlin to make the changes to your board I'd look for something NOT from ECS!!

I used to have this board and it was a beauty. BUT it takes DDR3 instead of the standard DDR2, so you'd have to upgrade RAM (for faster RAM, weee).

http://usa.asus.com/Motherboards/Intel_Socket_775/P5Q3/

It uses a P45 chipset which is listed with Intel for Core2Extreme compatibility. Sorry to be the bearer of previous bad news.

Thank all, I guess it is what it is...
