TIA for any info.
Yes as long as your motherboard accepts standard 184-pin DDR DIMMs. DDR is backwards compatiable down to PC1600.
i have some ecc ddr's from a 400sc i wanted to stick into a Dell 2400 and it wouldn't let me... it just won't boot.
ECC memory is a totally different compatibility issue. As long as your existing PC will accept non-ECC DDR and you are not mixing RCC and non-ECC DDR these standard non-ECC DDR should work.
Rep + for you, OP. Thanks. Ordered 2 (4GB Total) for my Vista machine. Great $30 for 4GB memory. wohhoo~~ (Yes, I ordered it separately with different name/address)
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.

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.
69ragtop said: Thanks OP. Crucial memory prices continue to fall.Yep . . . assuming the rebates continue to come. They've been rock solid for me, but lots of folks worried about Crucial's future. In for one anyways.
Great deal OP! I grabbed a pair. Has anyone tried to overclock this ram before. Thanks.

I previously had a pair of dual channel 2x512MB running at PC3200 speed. Now after adding these pair of 2x1GB PC3200 with a total ram of 3072MB, the motherboard is running at PC2700 speed instead of PC3200. Why is that?
I've heard upgrading to 3GB even at reduced speed may be a good idea. Is it true?

Why is that?I have the same memory set up in my Dell 4600 and it's running at 200MHz (PC3200).

I have seen PC3200 run at PC2700 speeds in the 400sc is the sticks aren't matched.
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.
Would love to get this but I've been running Corsair 3200 1GB at 235 Mhz & 2.5 CAS (effective 470 mhz) and I know this stuff is not likely to clock anything like that.
So I would take a big performance hit in memory speed, might not be worth the change.
Anyone have an overclocking experience with this memory?

I think this is the 3rd set of this stuff I have picked up!
