I have just acquired an ASRock Z75 Pro3 that I am going to pair up with an i7-3770 from an older system. I may be able to get a turbo boost out of the CPU? But I am trying to decide which memory to get? I will be running win 10 on here, but not sure if getting 16mb of 2400mhz memory is worth it? I already have a couple of 1600 MHz sticks (2x4) that I got cheap, but I can get 16gb (2x8) at about $70.00 these days. Latency is 9 on the 1600, and 11 on the 2400. Will the i7-3770 be able to use higher speed ram? Thanks for reading, LT :)

Yes it can be adjusted, can try XMP or try manually. If XMP doesn't work try setting manually to 1866, let me know the model # of the sticks and can propose probably good timings and voltage settings

heres how I see it

the chip is a non ''k'' so its locked [ no overclocking and the memory controller on intel chips like yours -- Memory Types DDR3 1333/1600

http://ark.intel.com/products/65719/Intel-Core-i7-3770-Processor-8M-Cache-up-to-3_90-GHz

memory you use over 1600 is considered overclocked now it may be fine setting the xmp but if you need to ''bump the cpu up to get the higher speed memory stable you may not do it so then you would need to ''down clock the memory

so for me and my opinion if a non ''k'' chip just go with 1600 memory set the xmp and all should be good to go

thing is you don't know how 2400 will act intill you fire it up on the non k chips .. I use non k and 1600 and all works well

I haven't worked with an asrock bios before. I am guess it is straight forward, and like asus, might have memory settings available? In the real world type situation, I wonder if 1600 to 2133 is noticeable...Since the CPU memory clock is 1333/1600mhz. I am guessing the 2 numbers refer to reg & turbo speeds? Will memory try to run up to the speed it is built as, or will it automatically throttle itself down with CPU memory clock and BIOS?

seems to me with a non ''k'' just play safe then sorry and just go 1600 ?? its not like you will see leaps and bounds with higher speed overall everyday use ?? [opinion]

to start its a older platform and do 1600 until it plays out and your ready to do a fresh to the day build by then you will be looking at ddr4 platforms more then likely anyway ?? [more opinion]

look at page 6 intel set up

http://www.tomshardware.com/reviews/dram-benchmark-fluctuations,4080.html

comes down to 1600 out of the box stable or higher speed as tradesman1 and I said may not be stable and you got a non ''k''' that may not make the required adjustments to your satisfaction ??

your call

Thanks guys, it is a processor I am pulling from an older X51. The darn thing was only built big enough to handle it's own stuff. Took me a while to get a mobo that was full size for this socket type, well, at a good price that is. I have 2 sticks gskill 1600 8gb (2x4) that I got for $30, but was mainly asking because 2133 and 2400 is still cheap, and wasn't sure if by using win 10 on this thing I might get use of 16gb @ a higher speed?
This is just a re-build type of system, and will do a new build when Skylake and DDR4 come down in price, probably in 15 months or so.

if me I would just slap that ddr3 you got in it and save the cash to sock it away - run what you got and see what comes after skylake

skylake to me is a platform I would skip over and wait on the next that should have a full ddr4 memory controller on it and not a split one [ddr3/ddr4]

too many funny things about skylake for my liking..

like this guy and his dilemma with ddr3 on it

http://www.tomshardware.com/answers/id-2914984/underclock-ddr3-ram-skylake.html

then the cant install win-7 from a usb cause intel removed some usb support [with out tool to insert whats missing ] ?? I guess its now going proprietary ??

no xeon support and for now limited cpu's to choose from

thing is you can do a haswell and not have any of this crap hang over its head ?? [opinion] so why skylake ?? don't add up today

Well, we'll see about Skylake, or whatever Intel has in the pipeline a year or so from now. I do have an i5-4670k build I use mainly. That was new about Sept of 2013, and seems fine for now... I just like to build away when I get a chance, and it isn't really expensive. Staying on the leading edge is way too expensive....

with intels tic-tock roadmap your still not bad off with that 1155 ive ... lol .. it still can hammer things out nicely and hang right in there with the haswell you got

skylake is not cutting edge its more like stick there toe in the ddr4 water before they jump all in platform
