5 out of 5 eggs

Pros: Excellent pair of sticks. Running 2.1V at 4-4-3-15 @ 800mhz on a M2N-SLi delux, and they're still cold after about 1.5 hours of gaming. The potential for these beauties is amazing, and that's still under manufacturer allowances ^_^

Cons: My board maxes out at 800mhz, so I can't go higher. Oh, and they're BIG!! No way these are going to fit side by side with my board.

BUYER'S WARNING: If you're running a M2N-SLi Delux board, you can only fit 2 sticks.

Other Thoughts: Really wish my board could fix a second pair. If I could I would definitely have bought 8 gigs. If you want 4 sticks though, I strongly recommend buying 2 first as these sticks are very wide. Some reviewers were able to bend a couple pieces out of the way, but in my case that wasn't an option. If you can make em fit side-by-side, then come back for the second pair.

4 out of 5 eggsCouldn't Get 4-4-3-15 Out Of Them

Pros: WOW!!!
These bit(hes are advertised at 4-4-3-15 @ 2.1v 800mhz
Well I couldn't get a 3 out of them, best I got was 4-4-4-12 but at only 1.95v 800mhz. So that was good. Same as the 2GB Corsair XMS2 800mhz I replaced with this 4GB set. Same 4-4-4-12 timings BTW.
So because I couldn't get a 3 (all reviewers could?) out of them I went with mhz, I kept the 4-4-4 but upped it to 15 @ 2.1v and got 1066mhz out of them and they can go more but my mother board maxes out at 1066. Now I'm going to do some gaming, COD4, Combat Arms, etc. and put them to the test. Well I tested them for 3 hours with no problems at those settings.

Cons: One of the reasons I went with these sticks was the 3 timing they got with them. Any other sticks with 3 timings are above $200.

Oh well. :~(

Manufacturer Response:

Hello, while these kits are rated at the specs you mention, your system must be up to the task. In our experience the M2N and the 570 chipset has a few quirks. I personally own the motherboard that you have and it seems you are doing very well with your overclocking and settings. We are always happy to assist our customers with settings on our support forums at the link below.
Thank you

5 out of 5 eggsGood Quality Ram

Pros: Good timings, runs at the rated specs and faster, stays nice and cool thanks to the giant heat sinks. Looks awesome in the side window of my Antec 900. Works with my p5n32-e sli mobo. I was a little worried about buying this ram since it was not on the qvl and I had read about some compatibility issues with this board but no problems so far.

Cons: None come to mind.

Other Thoughts: My new build chews up everything I can throw at it. Got most of it from Newegg.

5 out of 5 eggsGreat Memory, Great Price, Great Cooling

Pros: This memory performs extremely well, its got nice timings and stays incredibly cool to the touch.

Cons: A little cramped if they are side-by-side, and you need to make sure if you have an nForce-based board you enable the "SLI-Ready Memory" option to have the timings automatically set, with it off it defaults to 5-5-5-18. Overclocking hasn't worked too well for me, but It's not necessary so far.

Other Thoughts: Intel Q8300 @ 3.00GHz

5 out of 5 eggsI love these things..Vista does too

Pros: Stays cool runs at lower coltage than the set I replaced. I have the EVGA 680i boards that seems to kill memory, this should fix it. Yes, you must take your time to insert these babies in the slots but the nest just fine if you are patient. Just freakin awesome looking, reliable and have no problems rendering HD video in vista & Premier CS3 I noticed a decent performance jump going to 4GB over 2

Cons: I had no issues whatsoever..

Other Thoughts: Newegg..if you would implement a rebate service for your customers, I could only imagine the impact on your already great business!

1 out of 5 eggs

Pros: They perform as they should.

Cons: Thanks to OCZ beating me out of my rebate, I will stick to buying GEIL memory. They perform just as well and are cheaper. OCZ, you may have beat me out of my rebate, but you lost any future purchases from me.

Other Thoughts: These are too big for Gigabyte GA-MA790FX for one channel operation. They do fit in an ASUS M3A board, same channel. pictures do not do these beasts justice. An overkill. As my GEIL runs the same speed and settings and have no fancy heatpipe and not having heat issues.

Manufacturer Response:

Hello, we are sorry that you had rebate problems. OCZ uses a rebate house for all processing and if the made an error, we can straighten it out for you. Please visit our support forums at the link below and post in the rebate section for assistance. Mention that you were sent by the OCZ rep at Newegg.
Thank you

5 out of 5 eggsWOW!! Great Ram

Pros: got timings to 4-4-3-10 and clock to 900 at 1.8v (nothing set on auto) 100% stable with memtest86+ and a mix of prime95 + orthos, also gamed with crysis and gta4. I am very impressed with this rams preformance and it looks sweet with my uv water setup also 43.99 after rebate not bad at all for these results

Cons: umm... it cant teach my old dominator d9microns to do the same... it also didnt oc itself wtheck was ocz thinking ;-)

Other Thoughts: maybey i just got a spectacular pair or maybey this ram was made to go with my board/cpu (rampage formula/q9450 oc to 3.6) but either way ocz has earned themselves another purchase from me when i build a 1366/ddr3 triplechannel setup when i get my taxes back

5 out of 5 eggsMemeory that works hard for your money

Pros: While I hardly consider looks to merit a good rating for any hardware product I buy, this product is exempt from that. Not only are the large, efficient heat fins and excellent solution to my memory overheating problem, they are bada** looking. If you're hurting for high temps, or looking to upgrade your memory, go no farther than this.

Cons: Heat fins are so large they can be a little tricky to seat the stick on the first few tries, and if your channel slots are next to each other, it can be quite close, but not impossible.

Other Thoughts: Efficient, fast, good looking and powerful. No complaints to me, I'd definitely buy them again.
