Im really not all too knowledgeable about ram and timings and such, but im pretty sure that lower timings are better as is higher speed. What If one set of ram has lower timing but another has higher speed, whats the difference in that case?
So now that my question withing a question is done what would you guys buy? I was looking at 8 gigs of the gskill ripjaws but then i saw the new crucial balistix tracers

4GB DDR3 1600 CL7 and call it a day... But it would sure help to know what system it was going in to make sure you are not on triple channel (intel 1156/1366) or dual channel (AMD/Intel 1155).

Ram timings vs speed: http://www.tomshardware.com/reviews/ddr3-1333-speed-latency-shootout,1754-3.html

A bit old but the concepts remain the same.

Im gunna go 5ghz via 2600k
Does that change your recomendation at all?

EarthDog · Jan 25, 2011

For 24/7? No you're not...

Prime · Jan 25, 2011

No no via turbo boost 2.0

EarthDog · Jan 25, 2011

Maybe I dont understand how these things work... but In order to get 5Ghz I think you need to be around 4.5Ghz 24/7 which is doable with the right chip and cooling.

Not sure how you think that will happen though... I guess I just dont know enough about the chip.

For those of you who aren't familiar with it, let's recap what Turbo Boost is and what it does. Turbo Mode is an performance feature that automatically unlocks additional speed bins (multipliers) and allows the processor to self-overclock based on thermal conditions and workload. For example, if the Power Control Unit (PCU) senses that only one core is active and the other three are in an idle state, it will use the unused power and thermal headroom to overclock that single active core to ensure superior single-threaded performance. Conversely, if you are running a multi-threaded application, the PCU will measure the thermal headroom and if the processor is running cool enough it will overclock all six cores. On Sandy Bridge processors, Turbo can provide a 400Mhz speed boost in single-threaded workloads, 300Mhz in dual-threaded workloads, 200Mhz in triple-threaded workloads, and 100Mhz in applications that utilize four threads or more.

As far as changing my reccomendation, no it does not. Turbo adjust the CPU multiplier and voltage and does not touch the ram.

Okay thanks! Ive been seeing 4.8-5.2 in turbo all over the internet so i dont think it should be too hard

EarthDog · Jan 25, 2011

Thats on a single core with a 24/7 overclock of 4.8ghz...which is doable with some effort.

Its on all 4 cores, but almost always when you see those speed its people talking about hitting them for short durations, not using it 24/7 at those speeds/volts.

For example, my 2500k has been up to 5.1GHz, but for 24/7 usage I'm down at 4.4GHz.

I'm not saying you can't hit 5.0GHz and try to use it like that 24/7, just don't expect to be able to do it based on reading reports of people hitting 5.0GHz.

Prime · Jan 25, 2011

Yes I plan on having a 24/7 close to what you do

Sorry for sounding like an idiot, strange day for me haha

DaveHCYJ · Jan 25, 2011

No matter what your CPU and cooling end up being capable of, Earthdog's recommendation is a good one.

I would say also make sure your RAM is rated for 1.65v or less, if you want to be really conservative get 1.55v or less, but if you're shooting for 5.0GHz I'm guessing you aren't worried

I'm stuck on which to get, the Gskill Ripjaw X 4GB that has a CL7 or the Gskill Ripjaw 8GB that has a CL9. Both of em are DDR3 1333 10666 speed.
Lower latency timing or more ram?

I'm running the GSkill Ripjaw X 4GB with CL7 and find that it works great. Just bought another 4GB set to round out my DIMM slots. Also, Newegg currently has 15% off of all desktop memory. Check it out!

The 72 hr. 15% off sale is partly why i had asked,lol. I'm a noob at memory and don't see how CL7 is much faster than CL9 :-/

The Ripjaws X would be a part of a 1090T build i'm putting together, apparently reviewers say its compatible with AM3,even though it states "designed for Intel P67 sandy bridge". Anyways thx Flippedbinary

I honestly don't think you'll notice a difference with CL7 vs CL9 unless you are benching. And as far as being only for Sandy Bridge, someone says they work with AMD as well.

Straight up marketing. new platform, new ram
