1600Mhz VS 2133Mhz - Help for i5 2500k Build !

Hi,
I will be building a new computer, with a p67 mobo ( asus most likely ) and i5 2500k.

I am trying to figure out what DDR3 ram I should get ?

I am leaning towards Kingston due to their low failure/rma rate and the fact that they offer lifetime warranty, which i dont think is offered by other memory brand.

Also, I really do not want those tall heat-spreader ram sticks, i find them ridiculous and anyways they probably wouldnt fit because i'll probably have a big chunky heatsink on the CPU.

Finally, I want a minimum of 8gb of ram.

So the bottom line based on the limitation outlined above is that i can choose between these 2 kingston ram modules :


Kingston HyperX Grey Series 8GB (2 x 4GB) KHX1600C9D3X2K2/8GX : 105$
at newegg.ca

OR

Kingston HyperX X2 Grey series 4GB ( 2 x 2GB) KHX2133C9AD3X2K2
: 99$ at newegg.ca except that i would need to buy this bundle twice to get 8gb of ram, therefore the price goes up to 198$.

1 problem I can think of with going with the 2133mhz option is that all my ram slots would be filled up, and this would only give me 8gb, will 8gb be future proof enough at those speed so that i dont need to upgrade in the next 3-4 years ? ( so far I've always keep my computers for 3-4 years, for the past 5 builds, and I maybe do 1 little upgrade in between )

Also, I could alternatively get 4 x 4 gb of the 1600mhz ram, for a total of 16gb and 210$ which is pretty close to what i'd spend for the 4x2gb 2133mhz set, except that from my research 16gb is totally useless right now...

I know some of you will say, to get the 8gb 1600mhz and spend the extra money on the video card, however, my video card is already selected, im getting a gti 560 ti, for its decent performance and low noise... the more performing video cards do not interest me due to their increased heat and noise. Essentially, all the other component in my computer are pretty much selected and any saving on the ram would not be re-allocated elsewhere, just pure savings in my pocket.

I have 16 gigs 1600mhz, it is useless right but nice too have. if you go with that much ram be ready to bump voltage up to around 1.7 or so. My gygabyt board has fits feeding that much memory on 1.5v. Go with 8 gigs 1600 and use the exra cash for a 2600k chip. Mine runs nicely with H70 cooler at 5.0ghz, stable.

Go with the 1600MHz RAM, and 8GB like templar said. The 2133MHz RAM won't give you much if any additional performance and isn't worth the extra cost.

Even going faster than 1333MHz isn't truly needed. I'd go 1600MHz and run it at 1333MHz, only upping the speed to see that the difference is extremely minute.

Go for an 8GB kit, with 1.5V specs, like Corsair Vengeance or Mushkin Silverline. Get 4 x 2GB chips, to populate all the slots on the motherboard. 2133MHz~2200MHz is just cool to have as a number to show off ("Look, I can OC my RAM to 2200MHz! I WIN!!!"), but is useless when it comes to value, as it costs almost twice as much as the 1333MHz RAM kits and performs maybe 5% better.

Yeah, whichever kind you get, make sure it's 1.5v memory. That way, if you need to boost the voltage a bit you have some leeway. If you get 1.65v RAM, you can't increase the voltage any higher without risking damage to the CPU.

I have extremely bad luck with computer components, that as always been the case in all my builds, this time im making a conscious effort trying to get quality/reliable components. ( as opposed to before where all i was looking at was the best bang for buck / performance )

I would rather go with kingston for the lifetime warranty. They seem to have the best quality, here are failure rates for some popular memory brands :

- Kingston 0,30%
- Crucial 0,93%
- Corsair 1,41%
- G.Skill 2,73%
- OCZ 6,76%

Those numbers are for all models combined, if you look at Corsair and ocz they specifically have some awful models :

- 15,08% : Corsair Dominator 2x2 Go DDR2 PC8500 CL5 - TWIN2X4096-8500C5D
- 11,28% : OCZ Value2x1 Go DDR2 PC2-6400 - OCZ2V8002GK
- 10,11% : G.Skill NQ Series 2x2 Go DDR3 PC3-10600 - F3-10666CL9D-4GBNQ
- 8,01% : G.Skill NT Series 2x2 Go DDR3 PC3-10600 - F3-10600CL9D-4GBNT
- 7,19% : OCZ Gold Edition 2x2 Go DDR2 PC2-6400 - OCZ2G8004GK
- 7,14% : G.Skill RM Series RipJaws 2x2 Go DDR3 PC3-10666 - F3-10666CL8D-4GBRM
- 6,65% : Corsair XMS3 2x2 Go DDR3 PC10600 CL9 - TW3X4G1333C9
- 6,05% : OCZ Value2x1 Go DDR2 PC2-5300 - OCZ26672048VDC-K
- 5,88% : G.Skill HK Series 2x2 Go DDR3 PC3-10600 - F3-10600CL8D-4GBHK
- 5,65% : G.Skill RH Series RipJaws 2x2 Go DDR3 PC3-12800 - F3-12800CL7D-4GBRH
- 5,52% : Corsair XMS2 2x2 Go DDR2 PC8500 CL5 - TWIN2X4096-8500C5C
- 5,16% : G.Skill Standard Series 2x2 Go DDR2 PC2-6400 - F2-6400CL5D-4GBNT
- 5,15% : Corsair XMS2 2x2 Go DDR2 PC6400 CL5 - TWIN2X4096-6400C5C
- 5,07% : Corsair Dominator2x1 Go DDR2 PC8500 CL5 - TWIN2X2048-8500C5D

so definitively, corsair and g.skill is out.

I could go with some crucial at worst, but like i said i prefer lifetime warranty...

That being said, I cant find any kingston 1600mhz with lower than 1.65v ... If i want lower than 1.65v with kingston i need to get 1333mhz speed... but I want 1600mhz minimum.

As for Crucial, they dont have 2 x 4gb modules ... what the heck...

what shall i do ! ... i have no choice but to get the 1333mhz kingston ?

Personally I prefer 1600 CL7. Lower timings in general do not provide a bigger boost, however this dependent on application and can be a good boost for certain application - cannot remember the article.

Even based on your above stats I prefer Ripjaws. (For whatever reason seems more popular than Kingston @ newegg.)
My progression (All 1600 CL7): 2 x 2 (4Gigs) -> 4 x 2 (8 Gigs) -> 2 x 4 + 2 X 2 (12 Gigs). In no case did I have to raise Voltage, using 1.60V
Plan on trying 4 x 4 (16 Gigs).

Do recommend going with the 4 gig modules, which allows for >8 gigs downstream WITHOUT having to ditch some of your ram.
As to 8 vs more than 8. Currently no real benefit. However with 12 or more gigs you can run a SUPER fast Ramdrive 4+ gigs - makes an SSD look like a old 4 cyl VW compared to a V-8 sports car.

I don't know where you're getting your info, but all the brands I looked at had lifetime warranties on their RAM. G.Skill, Patriot, Corsair, Mushkin, A-Data, GeIL, etc. In fact, I couldn't find one that didn't have a lifetime warranty.

Oh, and one HUGE reason some brands have large failure rates is overclocking. People tend to buy OCZ, Corsair, and G.Skill for overclocking, and when they fry the RAM because they overclocked/over-volted too high, they RMA it due to "manufacturer defect" or something. Those failure numbers are unnaturally inflated because of that. Kingston isn't generally known as a good overclocking brand, so nobody buys them for overclocking, and they don't have inflated failure numbers.

You didn't mention Muskin, so I'm recommending the Mushkin Silverline 2 x 2GB RAM. 1600MHz, 1.5V and lifetime warranty.

Also, 1333MHz isn't nearly as bad as you make it out to be. TBH, the difference between 1333MHz and 1600MHz on RAM is so minute you wouldn't even see it in hardcore gaming. Only in benchmarking may it bring a little difference.

Hello i have i5-2500k and mobo p8z77-v lk and memory 2x4GB Crucial DDR3 4GB Dimm 1600MHz Ballistix Tactical
but when i set bios to default memory is working 1333? why ? and when i put it 1600Mhz i get blue screen freezing turn off my computer ? why how can i get my memory default valution 1600?
