PQI TURBO 1GB (2 x 512MB) DDR2 667 (PC2 5400) Dual Channel Kit Desktop Memory Model PQI25400-1GDB

Pros: it looked nice. it was cheap

Cons: Like a lot of other reviewers, one of my sticks was bad.

Overall Review: I bought this without reading the reviews. I went back and read some after i had my issue. Had I read the reviews first, I would have never bought this. Way to high of a failure.

Pros: one stick worked.

Cons: one stick didn't work.

Overall Review: I kept having lock up that looked like temp issues, I would have random shutdowns while doing something. Then would have trouble rebooting. Finally the mobo gave a error code that the something was wrong with the power supply. Finally narrowed it down to the DDR2 RAM.

Pros: cheap

Cons: Had to RMA twice, each time one of two sticks failed Memtest86 with multiple hard errors, tested on two motherboards at standard clock and voltage. opinion: Stay away.

Overall Review: hope you don't get my sticks later

Pros: ON MY ASUS P5WD2 PREMIUM I OVERCLOCKED MY PENTIUMD 2.66 TO 4.OO WITH NO PROBLEM.THIS RAM RAN AT 800 WITH NO PROBLEM.

Cons: NONE

Overall Review: I AM BUYING ANOTHER GIG OF THIS.

Pros: I would say price but paying anything for memory that doesn't work is too much$$

Cons: First set, each stick worked perfectly, ALONE. When they were both put into the system it would not post. Tried tweaking memory settings with no luck. The replacement set one worked the other did not...

Overall Review: After shipping them back twice and all this messing around, I wish I had gotten better memory from the start. I knew better, just trying to save my girlfriends dad a few$$.

Pros: Ran perfect right out of the box with next to my XMS TWIN2X-5400C4 @ 669 MHz. Running at 690 MHz with 4-3-3-9 timing on all 4 DIMMS.

Cons: I spent over $300 on my XMS nearly a year and a half ago and, well, that just hurts for what I paid for this.

Overall Review: For those complaining about stock timings...CHECK YOUR BIOS. 667 MHz is not the STOCK clock on these, but they are built to easily handle it by means of a small OC in your BIOS. MSI P4N-SLI, P4 530J 3Ghz @ 3.45GHz, 7900GT, XMS2 TWINX1024-5400C4. BF2 runs MUCH better with this in my system.

Pros: Price was outstanding. One of the cheapest prices for DDR2 PC5400. Not only is it FAST and CHEAP, it has the best overclocking ability from the other 667mhz DDR2's that I've tried. On air cooling, with just the heatsinks on the memory and 6 highpowered case fans I was able to overclock all the way up to 800 mhz stable without tweaking the voltage or the memory timings. The memory is paired with an Asus P5ND2-SLI board and a Pentium 4 631 Cedar Mill 3.0ghz processor. Also on aircooling, the cpu reached a phenominal 3.8 ghz without changing the voltage. I was able to run this completely stable for over a week now without one lock up, blue screen or restart.

Cons: Absolutely none.

Overall Review: Had no problems with the board reading the ram as DDR667. I highly recommend the motherboard to all who are looking one under $100. Unfortunately newegg doesn't have this motherboard so you'd have to look somewhere else. BEST BANG FOR THE BUCK! TRUST ME, YOU WON'T BE DISAPPOINTED!

Comments: This memory is working good on my new Asus P5ND2-SLI Deluxe motherboard. You have to configure it by hand to get the 667 speed. Contact PQI for instructions.
