I was hoping that would be the case Mondoman, however I was concerned as the motherboard manual says that to enable dual channel mode with two or four memory modules "it is recommended to use memory models of identical brand, size, chips and speed".
Also, would your view on the suitablity of the PC5400 memry change if I was to upgrade the CPU, which I mnay do early next year?
I would vote for option 2 also.
My DS3 (rev 2.0) manual says that when memory modules of different size and chips are installed, a POST messate indicating FLEX memory mode will appear. For a discussion of FLEX mode see: http://www.intel.com/support/motherboards/desktop/sb/CS...
If all else fails, just use the new 2 gb set only.
I think I put the system together back in December 2006. Is there an easy way to tell what revision the motherboard is? (or indeed, isn't).
The manual says it supports 1066/800/533MHz FSB. I was planning on leaving the CPU upgrade a bit longer, but is there a real possibility that could mean that new ones won't work on my motherboard? I can see this leading to another question i.e. which is the best value CPU upgrade!
CPU-Z will tell you the motherboard, what revision it is, and what bios it has. I also bought the same board in december of 2006, so it is likely that yours is rev. 2 also. You must update the bios to F12 in order to support the E6850 processor and other 1333.3 fsb processors. I also had a E6300 and 8800GTS and am pleased with the E6850 upgrade. I decided that the Penryn update due in Jan 2008 would not be that much more powerful, and that it would be surpassed by Nehalem only a year later.
Option 3, if you plan on OC'ing this unit. Sell the 1 gig of 5400 memory to recoup some of the expenses and then wait for a CPU to come around your budget later. Just my opinion, since RAM is really cheap right now. Here are some very good DDR2 RAM to consider, if you go with option 3. ALL are CAS 4!!!
I used the windows based update. I think it is the safest unless you have unreliable electricity and no ups. If you have no other PC, then print out all the installation and recovery instructions first, just in case, and also prepare a recovery bios on a floppy/cd/usb device. The update takes a while and looks like it may be doing strange things, so don't stop the process prematurely.
