3770K Mem Question

Hi I am about to buy some new ddr3 and wanted to know what I should go with for the new build for a 3770k on a ASUS p8z77 deluxe board. I am going with 16GB of memory but I am curious as to what speed I should be going with, is there much benifit to going with 1866 or 2133 memory over 1600? I will probably do some marginal overclocking of my cpu but from my understanding memory OC'n no longer depends on memory speed. What are the benifits if any to using 1866 or 2133 over 1600? Should I just go 1600?

Thanks

I have everything else figured out except for what memory to get..
System currently is:
p8z77-v deluxe
3770k(when available)
h100 water cooler(may rig it up push/pull config)
corsair 500r case
240GB Kingston HyperX SSD
3TB Seagate HD
GTX 680 vid card

I can't wait to get all the pieces and put it together, will sure blow away my old 9450. Last thing I am unsure of is the memory and hopefully will get answers here.

Thanks

"Subjectively," both the SB-E and IB share very similar IMC specifications (DDR3-1600), so it depends since there's only been a couple tests I've seen and neither matched-up.

Generally I recommend DDR3-1600 CAS 8/9 'Quad Channel' kits (4x4GB) specifically for the SB-E/LGA 2011 platform and XMP optimized for the CPU/chipsets. However, if you manually set the RAM then there's no advantages with an IB XMP optimized kit. Which brings up the 'problem' there are NO IB/LGA 1155 kits out there yet!

Going on the SB-E and the best IB i7-3770K I've seen:

Pretty much anything faster than DDR3-1866 CAS 9 does very little even in most all benchmarks. Sure SiSoftware Sandra 2012 will show an increase all the way up to the IB/SB-E maximum bandwidth, but it's synthetic. Next, mixing even (2) two sets of >DDR3-1600 2x4GB + 2x4GB is no guarantee of it working at Rated per set specs -- so think ahead.

The IB & SB-E can run ultra-low DIMM voltage RAM to 1.65v DIMM sets, there's a lot more stress on the CPU's IMC as the voltage goes up. In my case, SB-E, I have 1.35v DIMM RAM DDR3-1600 CAS 9 and I can OC the CPU easy @ 4.8GHz.

You have little figured-out in reality, since I cannot even know other than to ASS-U-ME what makes good sense together.

I can GUESS the ASUS P8Z77-V DELUXE will be okay, but when both the SB & SB-E came out there were more problems than I care to write in this post. Thankfully (SB-E), the ASUS was immune from a little known VT-d bug, but next time it could be MSI for all I know.

Next FEW cases can support push/pull H100's, a couple Corsairs but most Corsair cases cannot afford the room short off popping-off the 'roof' i.e. top vent screen. I KNOW the 500R will not fit in push/pull the H100.

My best piece of advice other than 'chatting' is to wait for 2 BIOS updates BEFORE getting the IB, the last few new releases from Intel have been a real PITA to deal with and work around. P67/H67 B2 bug->B3, SB-E CPU C1->C2 + X79 C0->C1, and some previews of the IB showed a decrease in some performance. Early adopters are Guinea Pigs.

Thanks for your responses, I am going to be a guinea pig. I hoped my going with some low profile memory that push/pull maybe possible but if it isn't that is fine. There is always the slim 120mm fans that may work for that as well.. Thanks for the memory advice will let you know how everything turns out after I get a cpu and have the system going.

All fast sets -> http://www.newegg.com/Product/Productcompare.aspx?Submi...

The Domimator's and Vengeance are by no means low profile, most 'good' sets aren't 'low profile.'

Sets like Mushkin Enhanced Redline - http://www.newegg.com/Product/Product.aspx?Item=N82E168... are low profile, but it's nearly impossible to beat the performance of the Dominators.

I know there's new sets coming...


I was considering:
http://ncix.com/products/?sku=65761

or
http://pc.ncix.com/products/productdetail2.cfm?sku=6544...

or
http://ncix.com/products/?sku=65664&vpn=F3-14900CL9Q-16...
The last is 40mm high..

I would just be as happy going with a 1600 set if I am not going to see much in the way of performance difference between them.


Keep in mind the machine I will be moving from is a 9450 with 4GB Ram and a GTX 275 video card.. I have had the computer for 4-5 years now(the graphics card is not as old but still dated) so I will be very happy to have a new machine. There maybe bugs at the first but I am sure it will still be much faster than my old machine :)  I hope at least..

If that's where you're shopping then the Mushkin Enhanced Blackline Frostbyte - http://ncix.com/products/?sku=65762&vpn=993995&manufact...

The KHX1600C9D3K4/16GX is a 1.65v kit and I really don't recommend 1.65v kits, especially a DDR3-1600 kit.


good point I have to check the volts each use, thanks for pointing that out :) 

The one I listed Mushkin Enhanced Redline Frostbyte 16GB 4X4GB PC3-17000 DDR3-2133 9-11-10-28 Quad Channel Memory
runs at 1.65v, not sure what it would run if scaled back..

My head is starting to swim..

You 'can' run 1.65v but it's not really recommended and I'm sure someone will scoff that I said okay. I can see 1.60 or 1.65v RAM @ DDR3-1866 or faster.

Personally, DDR3-2133 or faster is a a lot more difficult to keep stable than DDR3-1600 or DDR3-1866 with a reasonable CAS. I'm more concerned about my CPU OC and keep it stable vs juggling another variable.

When shopping memory there (3) factors that are the real determiners: 1. Frequency, 2. CAS Timings, 3. CPU's IMC. High Frequency + High CAS = crap vs High Frequency + Low CAS = good plus a DIMM & IMC voltages that won't 'fry' the CPU's IMC over time.

The reason I really like the Dominator's is because they're hand picked IC's and aren't a variable even when exceeding their 'Rated' limits a little. Both Dominator/GT and Mushkin are used by folks OC'ing. G.SKILL has the new lines of Ares, but the sets I've seen they set the VCCIO** too high @ 1.25v for 'my liking' which is a sign of poorly implemented IC's; ** (aka DRAM/QPI, VCCSA, etc -- CPU IMC voltage).

Q - what's the drive for a low profile?! // if it's for the Noctua NH-D14 then you've got to be kidding -- get a Corsair H100.

I have a H100 on the way. I do not think I will need to have push pull as I doubt I will be oc'n that heavily, was just something I was trying to keep open as an option.

I can sustain a 4.8GHz @ 1.4v OC on an i7-3930K @ 68C~72C on an H100.

Oh found another that is a little cheaper and uses even less power:
http://www.ncix.com/products/?sku=59978&vpn=F3-12800CL9...

one more question though. I notice they mention dual, triple and quad channel sometimes when refering to memory.. If I want to run 4 sticks of ram together should they been quad channel?

Channels - LGA 1155/1156 and most CPU/MOBO's are Dual Channel (2 or 4 DIMM), LGA 1366/X58 is Tri Channel (3, 6 or server more DIMM), LGA 2011 Quad Channel (4, 8 or server more DIMM).

The LGA 1155/Z77 is Dual Channel,but you can have 2 DIMM per Channel.

The G.SKILL Sniper SR2 low voltage are fine, and typical Frequency and CAS. On the Z77/IB CPU are considered 'Default' speed; same for the LGA 2011/SB-E DDR3-1600 is it's Default.

Good, I think that is what I will go with then. Price on them is pretty good, they price match so should be able to get 16gb for under a hundred bucks. Thanks for answering all the questions, thanks to you know a lot more about memory. Another 19 days or so I will have a 3770k(hopefully) and see how everything works out :)

Before buying the IB or i7-3770K, at least the (ES) have a OC'ing problem and run very hot, read reviews and IMO Early Adopter's feedback. Now perhaps the Consumer lines will have this problem fixed, but I strongly recommend you are cautious.

"Current 22nm chips have high voltage, higher than they should have. The values are similar to Sandy Bridge chips. Properly should be the default voltage below 1V and it is not now. But Ivy Bridge needs a lower voltage, at the same voltage as Sandy Bridge consumption and temperature is significantly higher due to higher currents in the chip."
