Yep, I need 2GB. If there were 1GB PC3200 DDR400 DIMMS at a good price, I'd get those for 4GB.
Here's an email to me from Mushkin - pretty nice to answer my questions - :
The basic green modules should be fine altho i have seen Dell tweaking their specs for memory using the spd program used on memory modules to be specific to their machine, thus purchase the ram thru Dell. i don't think this is a problem with the 8300, but let me know directly if there are any issues.
We package our Dual packs with exact match modules, ,you're right- because you're buying at the same time, they are all from the same lot - all good.
But, sadly, here's my latest post to Mushkin:
Got the Dell 8300 in on Wednesday and got the four DDR400 PC3200 modules yesterday. Pulled the originals and wrote down their configuration for my records:
RAM slots are numbered this way (from rear)
Slot 1,3,2,4
RAM, as installed from Dell, are two 128MB modules:
Channel A DIMM0 - Slot 1 (rear most slot)
MT4VDDT1664AG-40BC3 PC3200U-30330-C1
128mb, DDR, 400MHz, CL3
Channel B DIMM0 - Slot 2
MT4VDDT1664AG-40BC3 PC3200U-30330-C1
128mb, DDR, 400MHz, CL3
Installed the four Mushkin 512MB PC3200 Basic Green ~Weekend Specials~ today in slots 1,3,2,& 4, and unfortunately, they aren't working!
Couldn't even boot to a screen. The Dell immediately starts beeping away. Looking at the lights, it indicates, gosh!, a memory problem. Rats!
So, I pull the Mushkin modules, put one original module back in slot 1 to make sure all is ok, and it works fine. Power down, put the other original in slot 2 for the other channel, and boots up fine. Pull the original modules, and, with appropriate power downs, anti-stat band and all, alternate trying out one Mushkin DIMM at a time in slot 1 only, in case there is a bad DIMM. All individually, as the only DIMM in the case in slot 1, or all together, give the beeps, no bootup and no video.
So, now got to figure out next move besides an RMA from Mushkin!
