It is fully buffered. Other sticks dont even fit.
That is FB-DIMM but it's only PC2-4200F.
The system calls for PC2-5300F. (DDR2-667 Fully Buffered)
And socket 771 boards are very picky about RAM type/speed.

Fortunately 1Gb and 2Gb sticks are quite cheap these days.

You can ignore the ECC part of the description. All FB-DIMM is ECC.

I would go right into 4GB modules. Just at friday i got 2 pieces for $9.90 per piece with free postage ( http://www.ebay.com/itm/New-Micro-4GB-PC2-530 … -/111838425526? ). See no reason to buy 2GB modules - they heats a lot (65-72 degrees with cooler, around 100 without), so more modules, more heat.
Another thing i noticed was fixed memory frequency depending on CPU, with Xeon 5110 (1.6GHz/1066FSB) i wasnt able go over 533Mhz. When i changed cpu to Xeon 5140 (2.33Mhz/1333FSB), frequency went to 667MHz. So if he using PC2-4200F memories with 1333FSB CPU, this could be his problem. Not sure that 533MHz memories are supported with 1333FSB cpus.
Memory is cheap, CPUs are also for good prices, but im unable to find cheap cooler for 2nd CPU (sadly s771 have really uncommon mounting holes).
