Intel Q965 Express Chipset


Dell Boy

Recommended Posts

I'm wishing to add 4GB of strong ram to my soon-to-arrive new computer.

 

 

Dell OptiPlex 745 Mini Tower

Expansion Slots » 4 sockets

CPU Information » Intel Core 2 Duo

1066MHz FSB, Intel Q965 Express Chipset.

Windows XP, 64 bit

 

The fastest ram that is recommended by the Corsair compatibility check is:

VS2GBKIT667D2 Details

Memory Type » DDR2-667 (PC2-5300)

Size » 2GB Kit (2 x 1GB)

Latency » 5-5-5-15-2T

Format » 240-pin DIMM

Heat Spreader » None

 

After researching reviews at other sites, I'd like to use:

 

CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

TWIN2X2048-6400

 

or:

CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) TWIN2X2048-6400C4

 

Why won't these choices work in my new system?

Most OEM systems will not give you the option to run the memory at a higher Voltage for this system if it will support 2.0 Gig modules and you want 4 Gig I would suggest Twin2x4096-6400C5DHX as they will run at 1.8 Volts the standard your system will support. However, I have not seen this system and you need to make sure there is 2" of clearelce over the memory slots or they might not work as they are a bit taller.

But I would not suggest most of our XMS modules for any OEM system, if not this module set then our Value Select would be the best choice.

Thank you for responding RAM GUY,

 

I think that's good advice on the voltage consideration, others I talked to suggested that the Intel 965 would be OK with RAM configured for 1.9 volts. It makes since to me that the dueling voltages (1.8 v. 1.9) will lead to problems if the BIOS can't be altered.

 

Will the Intel 965 accept 2GB memory modules?

 

I'm fairly confident that 1GB modules are OK...

 

Also, if I go with the Value Select line, would you recommend the VS2GBKIT667D2 or are there stronger choices.

Yes that Chipset will see 2.0 Gig modules and the Twin2x4096-6400C5DHX will run great in an Intel I965 MB, just remember what I said about the clearance.

And Yes VS2GBKit667D2 is the next best choice.

I could only get a general answer ("yeah, that should work") from Dell as to whether the ram space clearance would be an issue with the Twin2x4096-6400C5DHX. Given that it's a mini-tower case I've chosen, I suspect there should be enough room and I've placed an order for the Twins.

 

Thanks for your help RAM GUY in identifying what looks to be great ram for my computer. I've even got room for another 4 GBs if need be...

I just pooped in a 4GB DDR2-800 C5DHX kit into a Dell Optiplex 745, BIOS 2.0.5, and it beeped at me about a half dozen times and remained at a black screen.

 

Going to a single DIMM didn't help.

 

Putting the stock DDR2-667 back in worked fine. And yes, ram clearance is just fine.

 

Not sure if this is an issue specific to this box or not, I just tried it for grins since I happened to have this memory here for a P5B build.

Please check with Dell and see if there is a BIOS Update and again as I said before but maybe I was not clear. The 2.0 Gig modules are compatible with this chipset, but the MB maker may not have included support for these high density IC's, I would see if Dell offers an option of 2.0 Gig modules with that system. The last part was assumed on my part that you would have checked, sorry!

 

Also the memory that came in the system was DDR667 does Dell offer DDR800 for that system as an option?

Dear RAM GUY,

 

Dell does offer two 2 GB memory options with the OptiPlex I chose. They are only available at 667MHz and are described as:

 

4.0GB DDR2 Non-ECC SDRAM, 667MHz, (2DIMM) [add $691.05]

8.0GB DDR2 Non-ECC SDRAM, 667MHz, (4DIMM) [add $1,328.55]

 

They also offer two DDR2 800MHz chips but niether is a 2 GB module. They are described as:

 

2GB DDR2 Non-ECC SDRAM,800MHz, (2 DIMM) [add $141.10]

4.0GB DDR2 Non-ECC SDRAM, 800MHz, (4DIMM) [add $595.85]

RAM GUY,

 

Thanks for being willing to replace the chips.

 

I contacted Intel a couple of days ago about the 2GB module issue and was eventually referred to a table of supported memory configurations for the DQ965GF motherboard today. These configurations appear to be consistent for the various Q965 motherboards they list.

 

DIMM Type, Smallest DIMM, Largest DIMM, Max Capacity

DDR2 533 256 Mbit, 128 MB, 512 MB, 2 GB

DDR2 533 512 Mbit, 256 MB, 1 GB, 4 GB

DDR2 533 1 Gbit, 512 MB, 2 GB, 8 GB

DDR2 667 256 Mbit, 128 MB, 512 MB, 2 GB

DDR2 667 512 Mbit, 256 MB, 1 GB, 4 GB

DDR2 667 1 Gbit, 512 MB, 2 GB, 8 GB

DDR2 800 256 Mbit, 128 MB, 512 MB, 2 GB

DDR2 800 512 Mbit, 256 MB, 1 GB, 4 GB

 

According to these specs, it doesn't look like a DDR2 2GB 800 MHz RAM chip is supported. It's also interesting that an 8GB RAM total is only supported for RAM speeds less than 800 MHz. There was also some information in an Intel document that a machine will beep three times and fail to start when RAM isn't recognized, a condition reported by continuum earlier in this thread when he reported trying the Twin2x4096-6400C5DHX chips.

 

I don't know if Intel considers "not supported" to mean "won't work" or "go ahead and try but don't call us when the machine blows."

 

I'm wondering whether I should consider >4 GB RAM if I'm unable to go with the 2GB 800 MHz chips (Twin2x4096-6400C5DHX) and must rely instead on the Value Select chips (VS2GBKit667D2).

 

Can 64 bit Windows XP with a Core 2 Duo (E6600) make use of more than 4GB RAM at 667MHz?

 

If so, how might computing performance and abilities of 8GB RAM at 667 MHz differ from 4GB at 800 MHz?

The Optiplex and RAM arrived today.

 

I put both of the Corsiar Twin2x4096-6400C5DHX modules in and the system recognized the change in RAM on the next boot.

 

Within the system properties I see:

 

"2.39 GHz, 3.93 GB of RAM"

 

No smoke from the motherboard so far and things appear to be working.

 

Thanks Ram Guy for your recommendation on the Twin2x4096-6400C5DHX.

Nice, good to know it worked. I never got a chance to follow up, it looks like I had a "memory size error" on the Optiplex 745 I was working on-- with a monitor connected to DVI the DVI-D adapter may never have initialized, which is why I couldn't get into BIOS.

 

The TWIN2X4096-6400C5DHX I tried in it is sitting happily in its intended system, a P5B-Deluxe WiFi AP with BIOS 1101. :D
