Went from 6GB to 8GB, only recognizes 4GB dual channel.

[bloodhound50]

O k guys. I recent upgraded my RAM from 6GB to 8GB so I could run dual channeling, however when I installed my new RAM it only recognized 4gb.

-Bios has been flashed
-RAM is known to be working
-All four 2GB ram sticks are 100% matches.
-Reseated several times
-ASUS M4a785td-m evo MOBO
-Corsair tx750v2 PSU (overkill for my setup)

Correct, G.SKILL, Corsair, Mushkin, Kingston, and Crucial. Also Patriot Memory seems to have corrected whatever issues I saw in the past and over the past year have a low failure rate; AMD is using Patriot Memory as a re-brand.

I'm still avoiding Patriot. I bought a couple of their kits that were highly intolerant to overclocking. My old G.SKILL DDR2-800 kit happily ran at 1000+, but the Patriot kits became unstable with as little as a 50 MHz overclock.

Less of an issue now that memory overclocking is much less common, but I've just found G.SKILL to be equal or better quality at a lower price.

Thanks for the insight, I think I will get two 4gb sticks in that dual channel kit linked above of G.SKILL

Kingston and Crucial from above are the only companies that produce their own IC's, the remainders e.g. G.SKILL, Corsair, and Mushkin 'pick' the IC's and produce the PCB/sink and assemble.

It entirely depends on line of kits; example Corsair Vengeance = poor OC (above rated), Dominator's = great OC, and ditto with any Mfg including G.SKILL.

Am I more likely to get a re-marked chip with the companies that don't produce their own IC's?

In your case it really doesn't matter, I seriously doubt you're going to buy DDR3-1333 and try to OC the RAM to DDR3-1866 or faster. The Brands I already listed are all good.

Further, I don't recommend mix-matching RAM: Brands, Lines of Brands, Density (GB), Frequency, CAS Timings, nor especially ever Voltage. In other words, the 'ideal' choice is to buy a Fully Matched Set; least chances of any problems.

You might also be aware that if you plan to O.C., the few slots filled the better. If you want 8g of ram, buy a 2x4 kit. If need be you can probably sell your other sticks on ebay.

 

[bloodhound50]

Because it generates less heat?

Gonna go with this RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231402

 

[Dogsnake]

No because fewer modules for the MB to maintain voltage regulation, timing on and better matching of sticks.

There is no point in OCing ddr3 memory. When you get up to 1333mhz, Ocing wont be noticed. If you want OC'd memory get 2000mhz+ memory. But to manually adjust timing and voltage on current memory is just asking for trouble.

 

[aviconus]

Not really. Memory overall is pretty cheap.

Good Kit. Enjoy
