Need Input! Which Should I Choose? Core 2 Duo T9900 or i7-820?

webadmin@intel.com — Fri, 27 Nov 2009 22:30:28 GMT

I need some input!

I'm in the process of "building" a new Dell Studio XPS 16 laptop. I can't decide whether to get the Core 2 Duo T9900 (3.06 GHz) or the i7-820 (1.73 GHz with 3.06 turbo boost). I do no gaming. I usually run 6 to 10 tabs of Explorer along with Outlook. I also run Photoshop, Word and Acrobat, usually one at a time but sometimes a couple at once, usually Photoshop and Word. I plan to get 8GB RAM. There's only about $300 difference in cost between the two processors, and I don't mind spending the extra money on the i7 if it will benefit me. I'm more concerned with consistent overall speed and heat on my lap. Are there any cons to the i7? Given my usage, will I get or notice any benefit from the i7? Will the combination of T9900, 8GB RAM and Windows 7 handle the apps I run without slowing/bogging down and not get too hot?

Recommendations and comments would be most appreciated!

Thanks!

DP55KG - why doesn't network adapter work or show up in device list?

webadmin@intel.com — Fri, 27 Nov 2009 21:07:33 GMT

I just built a new PC with the DP55KG motherboard. Installed 64-bit Windows 7. System works fine so far except it can't see the network. Device Manager shows two entries under "Network Adapters", but both are for the Bluetooth Device. Under "Other devices" there is an entry for "Ethernet Controller", but the icon has an exclamation mark on a yellow background, and when I view properties for it, it says "The device isn't using any resources because it has a problem."

In any event, when I try to connect to the Internet, I get the message "Windows did not detect any networking hardware".

Do I have a defective motherboard?

DP55WB BIOS boot problem with 2 monitors attached

webadmin@intel.com — Fri, 06 Nov 2009 12:58:45 GMT

I noticed the strangest thing: my DP55WB gets stuck on BIOS code E7 when I boot with a secondary monitor attached to the ATI HD4670 card.

It happens both at cold start, and at reboot.

In order to boot, I must detach the second (VGA) monitor and boot with only my primary (DVI) monitor attached. As soon as the OS is loading I can attach the secondary monitor again and all is well (until the next reboot).

It really is a BIOS issue, it happens *before* the boot device selection.

I use EFI boot, BIOS version 0144 (latest).

The system is not completely dead at E7, I can use Ctrl+Alt+Delete for another reboot.

I can reliably reproduce the problem:

(2 monitors attached) -> boot stuck at E7 -> Ctrl + Alt + Delete -> boot stuck at E7 -> detach monitor -> Ctrl + Alt + Delete -> boot OK

trouble shoot DP43TF POST Problem

webadmin@intel.com — Fri, 27 Nov 2009 21:37:30 GMT

There's some history associated with this problem; I'll try to keep it brief.

Over the last several months booting my computer with its EVGA 780i SLI mobo had become increasingly difficult. This mobo has digital readouts for POST and indicated that it was stalling on C1 which is a memory problem. I could start it, eventually by hitting reset over and over and eventually it would cycle through. Once it booted up it would work fine (you could turn it off / restart it etc.) until it was turned off for the night.

One day, that process, hitting the reset over and over quit working.

I had had the memory tested independently long ago and the memory was fine. I assumed the mobo was at fault again. (Been through several already) I have a warranty with EVGA to replace it.

Meanwhile I really needed access to my data etc.

So I procured an intel DP43TF mobo. I figured that I could put this in and use my components (intel core duo, SATA drives, vid card) to get the machine up and running and later on use this board to build another machine.

Well, I get everything installed. I check and double check everything.

When I fire it up this board is giving me 3 longs beeps at startup.

After a small search I find that this indicates a memory problem.

I'm thinking that maybe the memory is bad now.

So, being the good troubleshooter, I take the memory to a friend who has a machine that accepts DDR2 memory. And guess what? Each memory stick (independently and combined in both slots) works perfectly in his computer.

So, this means I have two socket 775 mobos that say they are experiencing MEMORY errors at POST when, in fact the memory is working fine.

This leaves CPU or Power Supply or the new intel board I purchased is bad out of the box. This happened with an EVGA board so I am not ruling it out. I just don't think that it is plausible.

Any ideas on what could trigger the mobo to have a POST error that indicates a memory problem when the memory is working?

A few questions I have:

If the CPU is faulty on the intel board what would the POST error code be?

If the Pwr Supply (which is a Thermaltake Toughpower 750W unit that is only 2 yrs old) is bad then what POST errors would this throw out?

Thanks for your help.

Which Intel chip do I have?

webadmin@intel.com — Fri, 27 Nov 2009 20:08:46 GMT

I upgraded (aactually clean install) of Vista 64 to Win 7 64 bit.

I was on the ASUS (Mobo) site for updated drivers.

I found one - Intel Chipset Inf Update Program V9.1.1.1014 for Win7 32bit/64bit- but not sure what Intel chip I have.

I ran a Intel INF Update Utility- but that was not helpful.

I wen to: http://www.intel.com/support/chipsets/inf/sb/CS-009270.htm

But not sure what I have qualifies as not sure which Intel family I have.

all I can say is I have a Intel Core i7 940 / 2.93 mhz/8/4.8GT

thanks

Windows 7 Home will run one physical CPU?

webadmin@intel.com — Fri, 27 Nov 2009 19:40:51 GMT

Windows 7 Home runs on one physical CPU. Does this mean I need the Pro version of Win7 to take advantage of a Core 2 Duo?

Intel Desktop Utilities Gone Wild!

webadmin@intel.com — Fri, 27 Nov 2009 19:31:13 GMT

I've been running IDU for about 3 years on this box, and today it went crazy. Firstly, the Diskeeper Lite program keeps opening its warning window-- about every 45-60 seconds-- the disk is not fragmented, since i defragged it the first time it opened... when i click IDU icon to attempt to open the program i get the error msg "service program is not active" .... i tried to re-install it, but that made no difference...

any suggestion? ideas?

TIA
