spec check on ram b4 i buy

teppic said:
You can always run RAM rated at a high speed at a lower speed. The best memory to go for is 2133MHz at C9 latency. It doesn't overwork the CPU, and the increase in speed together with low latency gives consistently good results in the few applications where it makes any difference.

Here you can see this in action, as the 2133MHz memory outperforms the 3100MHz memory - but we're talking differences that only apply to benchmarks (about 1-2fps)

The slower RAM is beating the Avexir due to it being double sided, the Hynix MFR ic's are only good for getting maximum Mhz not performance.

That's not the only benchmark that is like this, they all are and always have been. The G Skill TridentX 2933MHz is also beaten by the 2133MHz RAM. As I said already, the performance difference is from nothing to negligible, as every benchmark shows.

Yes because they are single sided Hynix MFR''s, all the RAM at over 2666 basically are, they are the only IC's to do it.

Double sided will always perform better than single sided untill you overclock the MFRs at 3500Mhz or more.

There is a post over at xtremesystewms that shows nearly a 10fps increase in BF3 by going from 1333-2133 (or there abouts)

1333MHz isn't always sufficient bandwidth for modern PCs, and I expect that's at a high latency like C12 too. Nobody has ever suggested people buy 1333MHz C12.

The fact that it really makes no difference to anything but benchmarks is why the reputable tech sites hardly ever bother reviewing memory, nobody wants to see graphs of equal length lines.
 
you guys have lost me in them last 3 posts lol, that means absolutely nothing to me lol, remember i am the biggest noob on here lol, its so much to get my head around and ive not even got one component yet, ive been reading loads i just need to start building it and doing some hands on learning as there is only so much reading i can take in without any form of pc in front of me :(
 
Like I said there is a nice post over at xtremesystems showing how BF3 benefits by around 10fps (may have been 8.9 but whos counting) from faster RAM.

Its simple,

Buy that 2400Mhz Patriot Venom RAM.

Only RAM that uses single sided Hynix MFR chips are slower than dual channel kits at XMP settings.

All RAM that is over 2666Mhz will be Hynix MFR's as these are the only IC's able to be binned (tested) this high.

Please show me the benchmark, it contradicts everything else on reputable sites. If you're counting from 1300MHz C12 RAM, that's entirely meaningless.

Yet more,

Review summary: Genuinely high-end products are released with the lure of exceptional performance. Our benchmarks show an 8GB (2 x 4GB) TridentX pack of DDR3-2,400 memory to be barely any faster, if at all, than well-tuned DDR3-1,600 memory. The explanation for what seems like a performance anomaly is actually quite simple: Intel's recent chips integrate smart, efficient caches that blunt the hoped-for benefits of running premium RAM.

Stop living in the dark ages.

Even 8 Pack would recommend faster RAM;):D

That's a comparison with 1333MHz, which as I've said, is meaningless. It's also a random post in a forum, not a reputable test on a tech site.

If you want to say that all the benchmarks out there on every site are wrong, and you're right, using an anonymous forum post as evidence, there's not really much I can say to that.

Its good enough and the people at xtremesystems know what they are doing, they aren't Bit-tech;)

With Bf4 coming out soon and based on the same engine I expect that to benefit from faster RAM too.

No you haven't. You've posted what some person has said on a forum. Please look at the benchmarks and reviews on every site out there, before telling other people they're wrong.

Its obvious you been looking at wrong benches then, especially ones that show dual sided dimms beating single sided.

Even the number 1 overclocker in the UK would say get the faster RAM to get better efficiency/performance, and don't try and tell me you know better than him.
