OCZ OCZ3G1600LV6GK DDR3 PC3-12800 1600 MHz Gold XTC 6GB Triple Channel Kits Review

Well I had read a lot of reviews before buying about DOA sticks, but figured at the price plus rebate, no one had a better deal.First let me say because of the concerns of DOA sticks I ordered from amazon instead of newegg or any other computer company because of return policies and that was a SMART decision on my part.all other companies require you to send back your defective merchandise before they send a replacement, well if its the only RAM you have, that means you can't use your PC for 2 weeks!In my case I did receive defects, at first I thought it was only 1 stick as the other two passed Memtest86 and windows mem check without problems.I asked amazon for a replacement and they sent the replacement the same day (2 day UPS!!!) and said to send back the bad RAM after I received the replacement, that is AWESOME customer service on amazons part.

Well I thought everything was running okay with the 2 sticks but shortly realized that when I tried to open any movie files (no matter the format) or actually just click on the folder they were in, windows 7 would freeze or shut down!I was about to cry (manly cry) because I had spent hours setting everything up on my new build and SSD and thought all my old data was lost!I had all my drivers updated BIOS configured to standard for cpu and memory, but couldn't access the files.I even re-installed windows, after hours of setting it up.Well an hour later UPS came with my replacement memory (remember 2 sticks I was using passed all memory tests).I popped in the first stick (like to test one at a time) and it ran okay, then I went into windows, clicked on the media folder and it OPENED!I was couldn't believe it, the problem was the memory when all the tests showed it was okay.Which means all 3 sticks were bad, not just the one (the one didn't even pass 5% of the tests).One thing I noticed was the replacement RAM had a green color to it (like pictures on amazon show) the memory I first received was black (I thought it was just the dye they used).

I rated it 4 stars because I know have 3 working sticks, which windows rated a 7.8 which is amazing.no issues, runs everything perfectly, and amazon was great with the replacement.the 1 star taken off was because of POOR quality control by OCZ, obviously this is a common problem and you probably have a 50% chance with your order.that has to be fixed.for $130 after rebate, memory that runs at 1600 8-8-8-24, 6 GB, you can't beat it.

oh and you have to configure yourself, if you are looking for an upgrade and don't want to mess with BIOS, don't buy this, if you are comfortable in the BIOS, go for it.just have to set the timing yourself and the multiplier.don't be upset that on default windows and your board see this as 1066 memory, the i7 chip is set that way, easy to change yourself though.8-8-8-24, 12X multiplier on standard bclock, and set your Voltage for the ram to 1.64 or 1.65(standard is 1.50 which is not enough, specs for this are 1.65)

Intel Core i7 Processor i7-920 2.66GHz 8 MB LGA1366 CPU BX80601920 Review

Pros:
It's my first build and coming from a Pentium 4 3.4 ghz in my Dell to this processor is simply amazing. I can now play Oblivion and L4D in the settings I want! Everything else it pretty much cuts through it like butter. It get a Windows 7 WEI of 7.6 3dmark Vantage CPU score P42500+ and I have it overclocked to 3.67 with blck of 184 vcore 1.225 with vdroop. Coupled with a Cooler Master V8 it's prime 95 stable (small ffts - 2 hours, large - 2 hours, blend - 9 hours) and LinX stable (max memory 10 runs) 75 degrees C max. Ambient 80 F

Cons:
None

Other thoughts:
If you are new to overclocking like I was here are some simple steps for a modest overclock:
WARNING: It is entirely possible to burn your CPU! Don't go crazy and set a high base clock from the start. Follow the steps!

1) download Realtemp.exe, cpu-z, prime 95, and LinX (google em)
2) go into your bios and increase the base clock by 5 (or 10 if impatient but remember my warning)
3) Load Windows and breath a sigh of relief if it does. But thats only 1/5 of the battle.
4) Run CPU-z to verify your overclock, close it then run realtemp.
5) Run LinX max memory, 3 runs. If it blue screens, restarts or errors then you've gone too far and you need to dial it down to keep your machine stable. Your last setting is your max overclock without adding vcore (cpu voltage).
6) If it passes with no errors and your max temps aren't above 85 C (some people use 80) then you're good, and you can add more base clock.
7) Go back to step 2 rinse and repeat.

8)Once you get to a speed you're happy with and it passes LinX, and is below 85 C, run prime 95 stress test for at least 6 hours of blend, 2 hours of small ffts, and 2 hours of large ffts. If it survives that then you're good for gaming and most everyday apps. If it survives p95 blend for 24 hours (no errors, < 85 C) then you're rock stable ready for mission critical or server work.

You can run Linx for more passes or folding@home SMP for further stability testing.

Finally don't expect much if you're using the heatsink that came with the processor.

Good luck. If I made a mistake somewhere please correct me in the comments.

BTW my motherboard is the EVGA X58 vanilla. The folks at the forums in their website are the most helpful and supportive folks you can find. Really thats the stuff that money can't buy, I strongly recommend their motherboards just for that. They have guides for more serious overclocks and guides explaining voltages, guides on optimizing Vista etc.

All the info about overclocking and stability testing comes from the stickied threads on the EVGA forums
