|  DDR2 memory speed and voltage?
I have a Gigabyte GA-MA78GM-S2H rev 1 motherboard currently running a AMD 4850e processor and two 2GB DDR2 800 1.8 volt modules. I in the process of upgrading the processor to a 905e which supports DDR2 1066 modules. Would the faster memory provide a noticeable improvement in performance? I should be able to sell the DDR 800 modules to recover part of the cost of the 1066.
The processor manual and the Gigabyte website indicates “1.8 volt DDR2 DIMM sockets”. Some of the 1066 memory modules I am seeing at new egg.com indicate 1.9, 2.0, 2.1 or 2.2 volts. If I leave the system voltage control in auto will the BIOS read the SPD and set the memory voltage higher (if needed)? I think it should but I don’t want to order something that won’t work.

No, I wouldn't bother. ddr2 800 is fine.
Before you replace the cpu make sure you update the bios to f8 or later using your old cpu.

I believe those RAM would work fine at a lower voltage, but at a slightly slower speed. What the mobo will do based on the settings in SPD, and what is in the SPD, is anyone's guess. As above, faster memory may not wortjh the extra $$.

 The new processor is working
I updated the BIOS before I ordered the new processor (no point ordering a new processor if your motherboard doesn’t work after a failed BIOS update). I also bought this heat sink/fan.
»www.thermaltake.com/product_info···rent_cp=
I am running a Silverstone Grandia GD02 case and it appears to have between 61 and 63 millimeters between the top of the processor and the bottom of the 5.25 drive housing and the above heatsink is one of a very few I found that were likely to fit. At idle the new processor runs 35 degrees C with the fan running less than 900RPM. The old processor ran 38 degrees C at idle with the stock AMD heat sink/fan.
My only complaint with the Thermaltake heat sink is that you must remove the motherboard from the case to change the processor.
6MB level 3 cache should in theory make DDR2 1066 less important. DDR2 800 is working with no problems.
Thanks for the timely replies. I am going to stick with the DDR2 800 for now.
