OCZ ReaperX HPC 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model OCZ3RPX1333EB4GK

Pros: Insane cooling. I upgraded from 4x1GB G.Skill sticks, and let me tell you, this blow it completely out of the water! I have it running overclocked @1686mhz w/Timing 8-7-7-27 @1.9v. This is *BY FAR* the fastest RAM you have ever owned. Thanks to this RAM alone, my Crysis FPS have gone up 9FPS over my old DDR2. Combined with a Q6600 & GTX, I am getting 67FPS in Crysis on all High and Q16x AA(I'm in XP and haven't done the Very High mod yet). Worth the cash 100%. Get this and overclock and you won't be disappointed!

Cons: Price I guess. Was s3v3n hundred when I bought it. Price when down ~7hours after I ordered... But newegg was kind enough to give me the difference back. That is why I ONLY shop and newegg, for the amazing support! Hats of you newegg! XD

Overall Review: My Rig: *Intel Q6600 G0 Clocked @3.8Ghz-w/Zalman 9700*4GB of this RAM*150GB WD Raptor*nVidia 8800GTX*ASUS P5K3 DELUXE Mobo*1100W PSU*Creative X-Fi XtremeGamer*Antec NINE HUNDRED w/120mm Middle & Side Fans added All fans are running @ Max RPM. Sounds like a 747 @ Take-off ;-) Temps: Idol: CPU=33C Mobo=28C Load: CPU=44C Mobo 30C

Pros: Nice design.....sped up my machine and doubled my ram qty OCZ....they are a great group of people who have the customers interest as their prime focus. The company realizes without taking care of customers, you have no business. They still care about profits, but are very customer centric(which is probaly one reason why they came out of no where a few years back and are taking loyal customers away from other companies)

Cons: Need better dimensions and better pictures on the websites since some mobo memory slots are closer than others. The last thing you want to do is buy this stuff and then it won't fit in your motherboard in the arrangement that you want.

Pros: Great heat sinks,you can`t ask for more.you will not find faster timing anywhere.customer support is great.

Cons: Can only fit 2 sticks in most boards.beware 1st generation sticks only read 1066 on most boards.OCZ is aware of this problem and will work with you to fix the problem.rma in most cases

Overall Review: As i said you can only fit 2 sticks in most boards,but if you remove the heat sinks and turn them around so they go away from each other they fit.

Pros: extremly powerfull

Cons: you can not put 2 sticks side by side, means that you can only use half of the motherboards max allowed RAM

Overall Review: the mfg needs to rethink the heat spreader on this ram or the motherboard mfg's needs to start spacing out the slots

Pros: Runs smooth as butter. Plug and play. Stays really cool under load. I have not tried pushing it yet, but no worries about it lasting. This is some solid RAM.

Cons: The manufacturer writes on the packaging that you can not fit these side by side. So that means if you have only 4 slots for ram, they do not recommend filling all 4 slots with the reaper.

Overall Review: The speed problems that other readers have might be the mobo and not the ram.

Pros: It works as advertised. Originally loaded at 1066 mhz, I changed it to 1333mhz, lowered the timings, and increased the voltage and everything has worked fine since.

Cons: These modules are huge, though they fit with no problem in my Gigabyte ep35c-ds3r board

Overall Review: Quick shipping from newegg

Pros: The first thing most people, tech savvy people anyway, look at when they look at RAM is the Latency. Unfortunately most people, even intermediate to advanced users, try to compare DDR2 cas to DDR3 cas and that quite simply is not possible. The latency on this ram is unbelievable for its speed. It out performs DDR2 800 at 4-4-4 and is far superior to the OCz Gold 1333 that it replaced in my system. Unfortunately I did not run a benchmark prior to installing this other than the Vista benchmarking program however with the limited tests that I did run I gained .2 (4.8-5.0) in game graphics and .3 (4.9-5.2) from switching out the memory. OCz makes the best DDR3 on the market and over clocking is covered under warranty up to certain voltage increases. Can not beat this RAM for the price...and it looks cool ;)

Cons: Install was complicated slightly due to the massive heat sinks and a tuniq cpu cooler is not going to fit now...

Overall Review: MSI P35D3 E6600 OCz Reaper 1333 Corsair 750 TX ATI HD 3650 (Soon to be GTX 260 Core 216) Antec 900 (first gen)

Pros: Fast shipping. Does its job.

Cons: If you have 4 slots for RAM on your motherboard, you are only going to be able to fit 2 sticks in your machine because the heatsinks are too fat. Do not try to fit them side by side because you might break the ram slot off your motherboard.

Overall Review: If you are running windows xp, you can only use up to 4gb of ram anyways. I heard you can unscrew the heatsinks and put them on backwards to make them fit side by side but that might void your warranty. Plus the black part that goes over your ram is too wide, I don't think it is possible unless you put the ram in at a slight angle.
