Pros: Best and fastest RAM I ever used. This is definitely best for i7 860. Defaults as 7-7-7-24 1.5v in EVGA E657 motherboard. No problem, just set DIMM timings to 9-9-9-28 1.65v in Bios and turn on XMP. Buy this!

Cons: None.

Overall Review: Just waiting for new generation EVGA graphics card.

Pros: Yes, The looks and preformace is Rock'in. These are running stable @ 1600Mhz.

Cons: None so far.

Overall Review: I started these up on my MSI 790FX-GD70 @ 1600Mhz @1.65v @ 9-9-9-15 and ran for 5 hours perfectly stable. Can't do that with just any brand. If you have this Mobo this is the ram you need for OC. They are solid preformers. Not to memtion the great heat pipe and fin heat spreader technology. They sit 1/8 from the 120mm CPU(Zalman 9700 on top a AM3 955 ) fan and the air is drawn right through the ram heat spreaders. I tried to send a picture.

Pros: I am now able to get this to run at 1063.8 X 2 (2133) in either set now.

Cons: I bought 2 sets of 4GB before going overseas. One set was bad, but my Son took longer than 30 days to tell me, so NewEgg was no help. Sent it back to Taiwan (+$51.00 shipping) and told Geil it wouldn't run at 2133. Geil told me the following:"We will replace your current two Dual Channel Kit as fully functional Quad Channel kit if you could send us all 4 modules back to Taiwan. We will also do the complete testing on the EVGA mobo as well. We want to see 2133MHz C9 works in 8GB total in your current system." Three weeks later they sent 8GB back, but one 4GB set was still bad causing all kinds of file corruption. I sent back the bad 4GB to Taiwan again (+$44.00 shipping). (continues below)

Overall Review: 3 weeks later I got the replacement 4GB, and it works fine alone as 4GB, but it fails memory diagnostics if I try to use it with other set (8GB). So, now I have 4GB in computer plus an unused set as a spare. Geil didn't follow through on their promises. 8GB will not work together as they promised, and they tested it on an Evga E658 motherboard instead of an E657 like mine. Other thoughts: I should have only bought one set of 4GB. It's a terrible inconvenience and expensive if your Geil ram is bad. Hopefully, you'll have better luck.

Pros: easy install. shipped fast.

Cons: none

Overall Review: would recommend to anyone

Pros: Ram runs well at low voltage!

Cons: Not really a con but you need to boot into the bios to get all you can out of this ram

Overall Review: Why Newegg would you combo this ram with XFX nforce 790i when they say it is not compatible with the mobo and causes freezing issues...

Pros: Purchased these with the Asus P7P55D board combo deal and saved $115. RAM scores a 7.9 on Win7/64bit. Settings are 9-9-9-28-2N at 2140MHz, 1.65v. Newegg please give us an option to purchase higher quantity in combo deals. I wanted 8GB but the combo deal was for 4GB only.

Cons: none

Pros: It would probobally work pretty well if it was sold with a compatible mobo

Cons: sold in a combo pack with the ASUS MAXIMUS III mobo and is not compatible. It is also sold with an Intel Core i7 860 but is also not compatible with that either

Pros: So i got this ram with a Gigabyte P55-UD4P combo. Worked like a charm. Have it currently set to 2000mhz with my i7 860 oc to 3.8ghz Memory stay very cool with the provided heat spreaders, but i still wish they could be removed if needed.

Cons: Heat spreader cannot be removed. Atlease i was not able to budget it
