Purchasing new ram for crosshair v formula

post #1 of 7
Thread Starter 
Got a new crosshair v formula from an RMA of my dead Crosshair 3, and am thinking about getting 8 gigs of sweet sweet ram.

Been looking at these:

http://www.amazon.co.uk/Corsair-CML8GX3M2A1600C9-Vengeance-1600MHz-Memory/dp/B00569K7LM/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&coliid=I2VXA97VJDKAKV&colid=25GM5Q8J5IS

Simply because theyre cheap and have the good old Corsair name.

Anyone have any experience with these, or know anything better? Will be going with a Phenom II 965

I would say if you could find it, the Samsung ULV RAM would be great. They're also inexpensive, but overclock very well. If you plan up upgrading to Bulldozer, they would come in handy since they could go to 1866MHz (which is standard for FX) so easily.

If you can't find the Samsung RAM, though, that Corsair set should still work nicely. thumb.gif

They're ten pounds more than the corsair, and have worse specs to boot. But I hear they should perform and oc well... Worth it you guys think?

If you don't want to spend the money, the Corsairs should work just fine.

However, if you want to overclock, go for the Samsung RAM. They have worse specs because of the voltage, but you can tighten up the timings and up the clock speed quite a bit with just a little bump in voltage.
(Corsair voltage is 1.5v, while the Samsung voltage is 1.35v)

I would personally say it's worth it because high RAM speeds and lower latencies on AMD platforms help with performance a TON (compared to Intel platforms).

Extensive objective, scientific RAM testing by numerous sources (including OCN member "damric" on an OC'ed FX-4100), on both AMD and Intel desktop PCs show no "significant gains" with increased RAM frequency or reduced latencies when the RAM is run @ ~1333 MHz or higher. The reason for this is that DDR3 RAM running at ~1333 MHz. is not a system bottleneck thus the only gains are from the minute reduction in clock cycle time. Real time per clock cycle DECREASES as frequency increases, which means you get diminishing gains by reducing latency as frequency increases.

While synthetic benches will show more theoretical gains than real applications, I personally would not pay much extra for RAM with higher than 1600 MHz. rated performance as the return on investment is very poor compared to using that money for a better CPU or GPU. Llano CPUs do show some decent gains because the GPU section can use the increased frequency.

The threads below discuss the test results from OC'ing DDR3 RAM above ~1333 MHz. with actual test results showing no "significant" system gains in real applications. The definition of "significant" for discussion of RAM OC'ing here means that when you OC your RAM that you can actually see or feel the change in real applications on your PC. If you can't see it or feel it even with a 50% OC of the RAM from 1333 MHz. to 2000 MHz. and with a reduced latency @ 2000 MHz., then most people consider this to not be a "significant" performance gain - the same conclusion reached by Tom's Hardware, AnandTech and X-Bit Labs in their DDR3 RAM OC'ing testing. If your conclusion is different, so be it.

Many people buy 1333 MHz. or 1600 MHz RAM and OC it as best they can and move on because there is such minute gains it's not worth spending a lot of money on higher rated frequency RAM for such little gains.

Everyone is free to do whatever makes them happy regarding RAM purchases and OC'ing. The technical info. and RAM test data posted here is for those who want to know --- before they spend their money, that there is little to no system gains in real applications, from the higher RAM frequencies above ~1333 Mhz.

Well, crap. There goes my info... eek.gif + redface.gif

I guess do what AMD4ME said...
