Crucial Ballistix 4GB (2 x 2GB) DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model BL2KIT25664AA80A

Pros: This is some great ram. I have it running at ddr2 1066/5-5-5-15 2t with only 1.8V. Completely stable. Going from cheap Corsair to this allowed to turn down the voltage on my processor as well while keeping the same speed. At stock speeds of 800/4-4-4-12 2t, it benchmarked at 9.2 gb/s. This compared to the Corsiar at the same timings and speeds which got 8.6 gb/s.

Cons: Can't think of any. I'll see if rebate comes back, haven't had any rejected yet this year.

Overall Review: This is at the top of its class when it comes to ddr2 ram right now. Tests have shown it running as high as 1245, but I'm happy with 1066 right now so I haven't tried. Maybe in a couple years when I get what will be at the time a cheap Intel.

Pros: Fast memory, fast timings, lifetime warranty

Cons: Was not stable at default settings. Machine turned off spontaneously. Need to manually specify voltage. 2V is specified on Crucial's website. Thanks for the tip, Sleeping Panda!

Overall Review: Running on an ASUS M4N72-E motherboard, X2 5800+

Pros: Sometimes, you get that "perfect part". This part is rated as a DDR2-800, 4-4-4-12 at 2.0V on the poackaging - However, after checking the EPP profiles present in the set I received, I saw it was actually binned at higher speeds. It is now working at the 1066Mhz speed, as it actually reports it as a rated speed in the EPP. (SPD, of course, complies with JEDEC spec.) Timings set to 5-3-3-3-6-11. I do not expect this to be common experience, but my personal experience with Crucial/Micron ram has always been exceptional.

Cons: None whatsoever.

Overall Review: Deliberately used a Noctua C12P heatsink with a Scythe Slipstream medium fan. It overhangs the first two ram slots and gives them much higher airflow than RAM usually gets - This might well have contributed to the RAM. The motherboard is also an exceptional design, with an 8phase power voltage regulator module design, which means the power the RAM receives is also cleaner than what one would normally find. However, all this does, at best, is uncover the potential of the RAM. I am very impressed.

Pros: Reliable and stable even at 1066 mhz with 5-5-5-18 timings and 1.8v! That's pretty good considering I have other memory from a different brand that is PC8500 memory and suppose to run at 5-5-5-18 with 2.0v, but doesn't run stable unless it is 2.1v. I also have another PC8500 from the same brand that is suppose to run at 7-7-7-20 at 2.0v, but doesn't run stable even at 2.2v.

Cons: No cons about the performance and reliability of the memory itself, but I'd feel a whole lot better about the memory if the market prices for memory were like they were back months ago.

Overall Review: This memory works better at 1066 than other memory I have that's suppose to work at 1066! I know from experience that not all memory works as advertised and not all people's reviews are reliable, so I recommend finding reviews on the web from sites that have a reputation of doing trustworthy reviews on a variety of computer components. I had found reviews on the web about this memory that I felt were trustworthy so I bought the memory and have been very pleased with it.

Pros: Works BETTER, and at BETTER settings than advertised. Using Asus P5Q-E MB, Q9650 Chip. I'm only using 1.9 VDC, at 867 Mhz (from slight o/C), and latencies at 4-4-4-12. THAT you can't beat. And, it's been doing that fro at LEAAST a month now. And, working HARD all 4 cores MAXED out for 20-30 min. at a time quite often. Stays on 24x7.

Cons: CHEAP Heat sinks. Had to put a 2-40mm fan active cooling solution on it. Temps without the active cooling were getting out of hand.

Overall Review: I've always been a HUGE fan of S**** T***** memory, they are cheaper, and have ALWAYS worked. BUT, this was only a FEW bucks more, and quality, I'm sorry to say for ST, is HIGHER. THIS CRUCIAL, IS GREAT! FAST delivery, 1 day as normal out of CA. to Vegas, and well packed. Can't lose with this memory. I'm using it on a RELALLY high end workstation (and 24 hour a day server of 12 domains worth of pages). NOT much in the way of server duty but, it does it ALL!

Pros: Inexpensive, good advertised timings, relatively low voltage, and actually programmed with SPD settings for up to DDR2-1000. These should overclock quite well though I haven't gone past their official DDR2-800 speed.

Cons: I bought 2 of these kits to replace a DDR2-667 set. The original RAM was manually set to 333MHz @ 4-4-4-12 @ 1.8V in the BIOS so I swapped in the new RAM thinking it would POST at the lower speed. On first boot there was no POST and I was getting motherboard beep codes for memory error. I reseated the RAM and tried again but it was the same. So I reset the CMOS to default the BIOS to 'Auto' and tried again. No POST but no beeps either. I powered down and began to remove the sticks and the one in slot #3 burned my finger! The other three sticks were cool. I was finally able to POST with one stick installed, manually set up the BIOS, and then I was able to boot with all four sticks. All four sticks will not run in memtest and neither will any combination of two sticks in dual channel (memtest freezes or reboots). Each stick passed memtest individually and I haven't had any blue-screens so hopefully all is well. I've tried but have been unsuccessful to replicate the no-POST situatio

Overall Review: Other than the strange behavior on initial install I have had no problems. Here are the SPD values programmed on these sticks from CPU-Z: 333MHz|4-5-5-15-20|1.8V 400MHz|5-5-5-18-23|1.8V 400MHz|4-4-4-12-24-2T|2.0V 500MHz|5-5-5-15-30-2T|2.0V

Pros: On my Gigabyte GA-EP45-UD3R I have this kit overclocked to DDR2 1324 6-6-6-17 @ 2.1v! That setting isn't rock hard stable however, enough to do Super Pi 1M I haven't tested the high frequencies stable yet but it can reach DDR2 1200 6-5-5-16 @ 2.0v DDR2 1108 5-5-5-15 @ 2.1v 8hr Memtest 86+ v2.11 stable

Cons: When I got this for $42 shipped I see none.

Pros: Phenom 9950 with Gigabyte board, plugged in with 2.0v and ran at 5-5-5-15 2T @1066Mhz, rock solid with 10hour of Memtest86 and Vista Memtest, Great Ram very pleased!

Cons: no case sticker...no biggie

Overall Review: Worked better then another (*-*Skill) brand I had to send back twice because it would not even work at stock speeds.
