Looking for ram, last two sets bad

post #1 of 10
Thread Starter 
I am in the market for some new ram because I gifted my Corsair Vengeance 2x4gb 1600mhz cl9 to my HTPC.

First try were these G.Skill. After weeks of trouble shooting and help here on the forum it was determined the ram was faulty.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231571




I ran to best buy and picked up a cheap set of PNY xlr8 just to get me back on my feet. One of the sticks wouldn't run at the recommended speeds no matter what I would do. I am very green to this so maybe that was my fault. Took it back to best buy.







I swapped my Corsair back in just to make sure its not the board or user error or whatever. Ram checked out fine, computer was stable again.


Real quick here are my specs.
3570K OC to 4.7ghz (i changed my OC back to factory and still had issues with the above ram with the exception of the Corsair).
msi z77a-g45 mobo
h100i
mx100 512gb
evga 850 gold modular
(RAM is pending)

80% of what I do is gaming. The other 20% is video editing as a hobby. I am using Adobe Premiere.
I am not sure if I NEED 16gb of ram for the latter portion but I just figure why the heck not. I am not too worried about spending an extra few dollars if some benefit can be seen.

Since I had bad luck with G.Skill and PNY I thought I would just go back to Corsair. Might cost a few more bucks but what the heck. After a lot of reading it seems 2133 CL9 is the sweet spot between speed and latency. I am sure this can be argued but i am sold on it.

This was my first choice. 2133mhz and CL9. (99.99)
http://www.newegg.com/Product/Product.aspx?Item=N82E16820233533

I almost walked out of frys with this yesterday but the CL11 scared me off. The 2400mhz seemed interesting though
http://www.frys.com/product/7887489?site=sr:SEARCH:MAIN_RSLT_PG

Seems like everything else at frys is 1600mhz for more money.

I am even curious about this one. Same 2133mhz CL9 but the voltage is lower
http://www.newegg.com/Product/Product.aspx?Item=N82E16820233671

Bottom line I have a lot to learn about memory still and I am just trying to find the best sticks for my setup. I would opt for another set of the corsair vengeance but they are the same price as the Pro and I get faster than 1600mhz at the same latency.

Thanks for your time.

Keep in mind the higher frequency kits you have to know how to set them up. That G.Skill kit is no standard RAM, it requires manual configuration with that motherboard. If you want something easy to set up, stick with DDR3-1600 or lower. If you get DDR3-1600+, just keep in mind even if you can't set them up to the high frequency, you can always set them lower like DDR3-1333 or DDR3-1600 and they should work fine just like any other basic RAM.

Plug and play kits are DDR3-1333 CL9 and DDR3-1600 CL11

Also, if you're playing around with higher speeds, lower latencies, and larger amounts of RAM it may be necessary to bump up IMC voltage - I've had this issue NUMEROUS times in the past. An unstable IMC can show as faulty RAM.

if you're looking at spending $100 on ram, get this kit. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231638

this and the cl10 version are the last of the Samsung hch9, see here what It can do! http://www.techpowerup.com/forums/threads/samsung-hch9-4gb-generic-ddr3-double-sided.166641/

a 1333 rated kit will do 2800 cl11!

and btw, even if you don't go with my suggestion, afaik 2400cl10 is a better pick than 2133cl9, which is what makes that 2400cl9 kit so special thumb.gif

G.Skill has the easiest RMA policy, and a lifetime warranty so RMA that stuff

yeah true that, they're still replacing 4/5 year old psc sets that died from overvolting.

I mean shh, that never happened redface.gif

Agree, that RipJaws X kit is great, also uses sammies so you just need help setting it up properly..

WOW. that set looks amazing. I think I need to brush up my skills on ram before getting higher voltage or frequency.

I bit the bullet and bought a second set of corsair vengeance 1600mhz cl9 just because I had it working fine.

Had no idea there was so much more to learn in the memory department. Feeling like I should have picked this set up though.

This was the kit I just sent back to newegg. Had them less than a month and the memtest confirmed they were bad. At least to my expertise, which is limited, told me they were bad.

How can I learn more about memory, OCing, what all the numbers following CL(9) mean, etc.

It's usually safest to choose the least overclocked, least overvolted memory, and all of the above products are overclocked.

There are no 1.65V DDR3 DRAM chips. All those chips are officially rated 1.50V or lower. Higher voltage ratings (opposed to tolerance for higher voltage) are never advertised unless the chip failed testing at a lower voltage. Worse, that testing by the module company is more lax than the testing by the chip companies.

Similarly there are no chips rated faster than 2133 MHz/CLK14, but I seriously doubt 2133 MHz chips are found on any retail modules, regardless of their advertised speeds. Most likely even the fastest rated modules use 1600 MHz/CLK11 chips, at best, and sometimes those chips are rejects, no-name, or nonprime, and sometimes you can find out from the reviews and photos at . http://www.ocaholic.ch

Memory speed makes very little difference with CPUs because of their big caches. OTOH doubling the speed of the RAM on a graphics card can almost double the performance.
