no so-dimm is laptop

make sure these are low density chips for maximum compatibility (more chips = more compatible).

the high density are cheaper by nature of less chips (usually half as many). alot of old mobo's freak out when they see the higher density ram and do not accept it.

ecc has an extra bit (thus an extra chip). most mobo's that do not take ecc do not work with ECC memory.

oh wowzers! what a cheap price. so bummed, paid much more a few months ago

cawman said:these also work in a Dell 400SC, even though Dell specifies ECC ram. Just upgraded to 2 GB.Right. Just be sure not to try and mix any original ECC with these.

I hope it's falling because Christmas season is nearing. In for one.

Got one for my other 400SC. Thanks OP.

Great deal OP! I grabbed a pair.
Has anyone tried to overclock this ram before. Thanks.

I just bought mine a week ago, the rebate for that period is $30. Could have save 5 bucks more...

BTW, my old machine accepts only 1GB max so I got another stick spare, don't know what to do, sell it perhaps.

I've heard upgrading to 3GB even at reduced speed may be a good idea. Is it true?

I have seen PC3200 run at PC2700 speeds in the 400sc is the sticks aren't matched.

MrLateNite said:Warning: These do not work in dual channel 3 or 4 GB mode on a Dell 8300 system. They only will work as a single pair in the system (either single or dual channel), however, never as a quad / as a pair with any others.

I have had PC3200 Kingston value ram, 4x 512MB in dual channel mode running about 2425 MB/s throughput for the last 4 years.

I installed 4 chips of these (ordered last week from Frys at $20 AR vs $15 now )

I then used MemTest86 to test the memory. As soon as the memory got to 1.0 MB test address, it started failing on every address. Windows failed to load as well.

I tried every configuration of 4 chips. 4x 1GB, 2x 1GB + 2x 512MB in 4 different orders, both utilizing dual channel and not. No configuration other than: 4x 512's or just 2x 1GB's would fully work. (and 2x 1GB's worked in either single channel at about 1690 MB/s or dual channel at 2585 MB/s, about 2.5% than 4x 512's.

The chip date codes and mfg info were virtually identical on all 4 chips I received over 2 orders.

Running extended MemTest86 now on just a pair of these to ensure they are good themselves, which they appear to be in the basic tests.

Just thought I'd warn others to save money if they had plans on running 4GB dual channel on the 8300's. BTW--Even with 4GB installed, MemTest only could 'see' 3GB exactly, but Bios reported 4GB. I was hoping for 3.25 or 3.5, but 3GB seems to be the most that the 8300 Bios lets apps see.

Thanks for the warning.
Just curious but isn't that issue more a limitation of the 32-bit MemTest86 app or the 8300 BIOS? I have 4GB of these same Crucial PC3200 sticks running dual channel with no problems in several ASUS socket 478 MB in several servers and all see the full 4GB in dual channel mode under XP 64-bit but only 3GB in DOS based apps like MemTest86.

actually two!?
