Specs: Windows Vista/32-bit, C2D E6700/3 gigs 667 RAM
Hello and thank you for at least viewing the question: I have the eMachines T3604 w/C2D E6700/3GBS 667RAM/Vista 32-bit..425w PS...GT220 nVidia Vid Card.....the PC runs well. I'm curious if you think there's an outside chance that the mobo will support 1066Mhz RAM...the pdf for the D945GCL mobo and BIOS only lists 667RAM the max....but because of the open ended BIOS written for it (and the only from eMachines) surprises abound: such as running more than 2 GBs of RAM, and the C2D going in without a hitch, straight out of the box. The Intel pdf for the mobo says the RAM will run AT or BELOW the CPU FSB...support 1066 CPU FSB for C2D..and while there are no overclocking voltage options to speak of, I can select timing of 400, 533, and 667 RAM selections. Maybe set it for 533 and run it as an inferred 1:2 ratio? The chipset would either set it at 533 or drop it down to the fastest single channel set up with all the RAM being the same speed. (Don't think any more than 3 gig is prudent, vid card has 1 gig memory and want to address it). I'm wondering if you have heard of anyone getting 1:1 ratio @ 1066mhz from a D945GCL mobo...at 1:2 ratio, wouldn't there be a speed bump anyway with the 1066RAM having more modern voltage use and memory utilization? Would you consider it as an upgrade option or not? Thank you for your consideration either way.

"isn't 667mhz RAM a bit faster than 533mhz RAM"

Technically, yes. And DDR2-800 is faster than DDR2-667, & DDR2-1066 is faster than DDR2-800. And if you run memory benchmarks, you can confirm that. But memory benchmarks are designed specifically to test memory bandwidth so of course they would show a difference. Real world benchmarks are another thing altogether. Those benchmarks will show gains of just a few percentage points. Certainly not worth spending $75 (or thereaboouts) for 3GB of DDR2-1066. How is it that you have the money for RAM but low-balled the video card? That is where your money should have been spent, especially if you want to play games.

Thank you Jolicloud for the links provided,however, I'm aware of the Coreyville2 specs and what's posted by eMachines/Gateway/Acer...as well as Intel....so I don't know if 1066mhz DDR2 RAM would even POST. I guess the question I pose concerns the chipset more directly. Is there a flaw in trying to run a 1066mhz RAM (@533 from the BIOS, possibly) or do you think the chipset is hardset @ 667 Max? I have seen where 800mhz RAM would operate (but @667----which is a fear, I think). The BIOS was open-ended to allow for the C2D E6700 to be installed @ 1066mhzFSB...do you think with 1066mhz RAM it would POST at all? 667mhzFSB for RAM would be a default max? My current DRAM:FSB ratio is 10:8.......

"My current DRAM:FSB ratio is 10:8......."

The optimal DRAM:FSB ratio for that setup is either 1:1 or 2:1, so you should be running either DDR2-533 or DDR2-1066. Set your current RAM to run at 533MHz (if that's possible) or just leave it as-is. A RAM upgrade would be a waste of money, there'd be no significant perfomance increase. If you want to invest your money in something, get a decent video card. The GT220 is pretty low end card & isn't much of a gamer, if that's what you're after.

Thank you so much , riider, for the input: the GT220 was all I could afford at the time and think a GT280 or so might be more complimentary to the socket 775 mobo....it has PCIx16 v1.1, so I fear a bottleneck in the PCI rails, ya know? At any rate, I couldn't agree with you more on the marginal performance. I really appreciate the input on the RAM as well, but isn't 667mhz RAM a bit faster than 533mhz RAM? Do you think it would boot with 1066mhz RAM? Seeing how the mobo is 2005-7 tech, I thought someone may have tried this already in the last few years...again, THANK YOU so much for the input---I need the sounding board before I consider some quicker RAM!

The Vid card was bought a few years ago....I've just settled for it for now....the question of the RAM upgrade was just that....a question. No money has been doled out for an upgrade in that regard, but if real-world bench marks wouldn't show an improvement, perhaps I'll just stick with the 667RAM and tighten up the timing @4-4-4-12@667mhz....I'm very glad to have received your response to my question and thank you for taking time to address it....most helpful sound board!! Have a good day!!!
