Building high-end C2D - motherboard/memory question

Hey all,

I'm building a new PC for high-end server/database work, and I've got the following parts picked out:

4 x 1 GB of OCZ Platinum DDR2 1000 (PC2 8000)
Intel Core 2 Duo E6600 Conroe 2.4GHz
ASUS P5B Socket T

I had problems with my DFI LanParty Ultra-D when I installed four sticks of RAM in the motherboard - the timings skyrocketed and it failed to run in dual channel mode. I hadn't consulted the motherboard's manual to see that it can't handle more than 2 sticks of RAM in dual channel mode. Annoying.

Are the new motherboards (specifically this one) the same way, or can it handle 4 sticks of RAM at 4GB with no loss of speed? Will there be overclocking issues - can it be overclocked better with only 2 sticks installed?

Thanks!

why don`t you go to the mobo site and check it out.....google it if you have too...
 
It appears that the GIGABYTE GA-965P-DS3 will work with 4 modules in dual channel mode, but it says nothing in the manual about speed being reduced.

The Asus board originally referenced cannot handle 4 sticks of memory as per the manual.

Is this not a big issue for most people? You'd think the manual would be more clear about it for all manufacturers...
 
Download The Manual :

If it was me.... Chips is chips.... and you can run them however you need to the Money that you are probably wasting by having 4 GB of High Crank...
You can buy good lower clocked stuff that will do the same thing.

Server and Database work requires stability and Error Correction , and that is also contrary to Overclocking. If you actually need that kind of memory you will end up into a server/workstation motherboard.

And there is No Practical Reason for 4 gigs....I'm sure once you do some reading you will learn this...
You are better off if you want a Conroe to spend the money to get a Better Motherboard Chipset, and you will be happier.... (975x)

There are many articles floating aroud here that shows chips are chips... and it is just how you run them.
 
No practical reason for 4 GB? How about multiple instances of WinXP using VMware, each using 768 MB of RAM? Should I just rely on virtual memory?

That said, I'll look into different motherboards. I just want to find one that supports 4 GB of high-speed memory at a stable overclocking speed for maximum performance of a personal server.

Then you should be looking at Dual Processors and a Tyan Board..... that way it can be Ran Discretely and Have the ability to easily support that kind of memory...

Conroe is a desktop Chip... not really for what you are looking for... but Xeon might have been updated to the new core... but I'll warn you the Motherboard will be High Dolla....

There's no manual in English on Asus's website.

Right Here :

slightly different Board in PCI-X layout.... ... but Memory will be identical.

Excellent, thank you very much. I see the memory layout for the types of chips that will accept 1066 Mhz on the board (up to 8 GB), but how do I know which memory manufacturers use which types of RAM?

For example, I know that Patriot/G.Skill/etc often use different memory chip makers - is there any way to find out which major manufacturers will work in a 4x1 or 4x2 array?

Memory controller is on the motherboard, rather than the CPU like your Ultra-D, the memory doesn't downclock... As for 4gb of ram, unless you are using a 64bit operating system, it won't do much good..32 bit windows won't fully use 4gb of ram, it will show up as ~3.25gb. Overclocking may be slightly limited by using 4 sticks of ram as well, but shouldn't be a major impact.

I will be using Windows 64-bit or Windows Server 2k3, so that won't be an issue.

As for the memory controller comments, the manual seems to only work with specific DS chips, and I have no way of knowing whether or not Patriot/OCZ/etc will use those types of chips. Annoying, but I'll just give it a run with 4x1GB of Patriot 1066 Mhz memory and see what happens. RMA's with Newegg aren't so bad. 🙂
 
All the high end DDR2 is all Micron Chips.... except for the bleeding edge stuff which could be winbond chips....

I have two friends that have bought the Deluxe/wifi version of this board, and One went with Corsair, and one went Crucial...... The Deluxe would be a good choice for you also unless you need all that stuff on the Pro version...
 
Cool stuff. I ended up getting:

Core2Duo E6600
Asus P5W DH Deluxe
Enermax Noisetaker 485W
4x1 GB OCZ 1000/PC8000
36.7 GB 10k SATA Raptor

I have a CoolerMaster case and 2x150 GB Raptors laying around here for data in RAID-0 with daily backups to an external USB HD. Thanks all for the help - hopefully it all works and is a significant improvement over my Pentium-D right now.
 
4 dimm speed issue is an amd problem, NOT an intel problem...

unless recently intel can't run 4 dimms at full speed.. something got changed..

That's VERY expensive and you will be limited to 5300 speeds. It MAY O/C but probably not. The system also won't see all of the 8192 due to addressing (much as many systems that max out at 4096 don't see it all - without using a trick like "memory hole" or NUMA in workstation/server chipsets)

The professional is a good board if you need workstation features - namely PCI-X 133MHz slots. 🙂 It overclocks well and is extremely stable according to folks at xtremesystems.com. 🙂 There is no speed penalty to having all the slots filled with 1GB chips. I'm doing exactly that using GSkill DDR2800 memory. Everyone says that memory is great for o/c. I was going to order the X6800 but decided to get the E6600. (the difference spent on the X6800 is better spent around the holidays on something called Kentsfield. :laugh: ) The memory won't even break a sweat running the cpu at 3.6GHz - and that will scream - if the cpu is up to the task. I have a tuniq tower with a block that was precision faced (lapped) and passed to .0001" on the DNC inspection. 😀 It keeps a 3GHz FX60 tame. :Q
 
Awesome - thanks for the comments and suggestions, everyone!

Is there a guide to overclocking for the Core2Duos at all, much like the A64 guide?
