5 out of 5 eggsGet it!

Pros: Love this ram. Its fast, good looking, blue and well worth the cost (if its high when you're reading this).

Cons: None so far. Nothing to remove an egg for, but they need to include the optimal timings for the advanced areas, like tWR, tRFC, tWTR, etc.

Other Thoughts: The Intel DP45SG mother board will not automatically pick up the correct timings, it put it as 9-9-9-24. But after putting it at the correct timings and adjusting the advanced stuff, it increased the boot speed and the load in times for several games.

It was kinda hard to get the ram out of the packing, but I guess that's a good thing too

5 out of 5 eggsSo far so good

Pros: Great price. Perfect set to max out my 790i Ultra. Good looking.

Cons: None

Other Thoughts: This replaced a set of Patriot 2x2GB and so far has worked great. I normally run it linked with my QX6700 with 1066 FSB. 7-7-7-21 and can be set lower. This is a great set of ram.

5 out of 5 eggsExcellent Upgrade!

Pros: *Works at 7-7-7-21-2T
*Easily tweaked in XMP

Cons: *Blue. I hate blue in or on my computer whether it is an LED, paint, or just the heatsink on my RAM. I fail to understand people's obsession with the color. Especially LEDs (I enjoy my night vision!)
* wan't really a con per se...just see other thoughts.

Other Thoughts: So when I first bought this RAM and adjusted the timings, it felt like it was running slower than my previous RAM (, but after doing some performance testing, it did prove to run faster and actually appears to run faster now. Maybe I just needed to give it a swift pat on the romp to get it to work right :)

Also Newegg, I shouldn't have to find out the CR of my RAM myself, please put it for me next time, thanks!

I would like to add that this is the only RAM that is 8GB, comes as 4 sticks, and has CL7. Absolutely perfect combination, wish this wasn't the only kind of RAM in this combination; would like to see other color options, etc.

3 out of 5 eggscan't do it

Pros: looks great

Cons: All I can get out of it at 1333 is 9-9-9-28 at 1.59v, at 1066 I can drop to 8-8-8-24 at 1.53v, haven't been able to run stable at the stated 1333, 7-7-7-21 at 1.5v yet.

Other Thoughts: Maybe some more tweaking will get it to specs listed but I shouldn't have to. Always liked G.skill. I don't think I have bad memory cause all 4 sticks operate exactly the same.

Manufacturer Response:

Dear Customer

We can surely help you achieve the rated specifications of the RAM. This memory is definitely capable of advertised values. Please contact the G.Skill support team with hardware specifications. Once you manually input DRAM frequency, timings, and voltage, the system should be ready to go. If your motherboard supports XMP/DOCP/EOCP, enable that and the motherboard can automatically detect and configure DRAM settings. It is unlikely that the modules are defective, so contact us directly and we will make sure the memory is working fast and stable in your computer.
Thank you

Quality and customer service are our top priorities.

5 out of 5 eggsGreat Ram

Pros: Works great haven't had any problems yet, has a windows index score of 7.6. Great for gamers like myself

Cons: not really a con unless you intend on putting an all-in-one cpu liquid cooling unit. For example,

Other Thoughts: I really like the look and feel of this ram, The Heat-sinks look pretty cool with the ridges on top, i felt like i was less likely to short out this ram when i was installing it, because of the the plastic heat-sinks that are on them.

My Build :
G.SKILL Ripjaws X Series 8GB (4 x 2GB)
AMD FX-4170 Zambezi 4.2GHz (4.3GHz Turbo) Socket AM3+ 125W Quad-Core
EVGA GeForce GTX 560 SE (Fermi) 1GB 192-bit GDDR5
GIGABYTE GA-970A-D3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
60gb SSD
320gb HDD

Runs every game and program I've thrown at it so far no matter how heavy

5 out of 5 eggsGood memory

Pros: This seems to be a strong and very capable set of memory. I read that they were specifically designed for Intel chips a day or so after I ordered them, so I was a little worried until they came in and I used them in an ASUS M4A88T-M motherboard. If they work like this with AMD chips, I would love to see how they perform in the environment that they were designed for.

Cons: None that aren't my fault!

5 out of 5 eggsAwesome

Pros: Great Ram, really fast, and not a single issue here so far. Good overclocking room, and doesn't put out too much, of those of you using a fan to cool the cpu.

Cons: Nothing I can think of. Met my expectations perfectly.

Other Thoughts: Good ram for the price, If you want over 4GB of ram then you should consider this
