i7-2760QM cheapest Intel processor that runs 1600mhz memory?

Curious if the i7 2760QM 2nd gen processor is the entry level CPU that actually RUNS DDR3 1600mhz memory? I know some other older i7 processors(Like the 2670, 2630 etc) will accept 1600 DDR3, but will not run the memory higher than 1333. Just want to verify this info.

 

Intel does advertise ability to run 1600MHz memory,however I would think laptop manufacturer would need to support that option in the BIOS.If the laptop,that you are interested in, is being offered with 1600mhz memory option,then it likely does.

Why do you need to use 1600Mhz memory ?

 

It matters not about the processor, but the chipset.

And I wouldn't look at the official intel site for memory limitations. They say that the 2630 and 2670qm do not support 1600 mhz, but they do with the hm65 and hm67 chipsets.

An Asus representative tested 1866 mhz ram with the 2630 and it worked: G73Sw tested with Kingston's new Plug N Play Hyper X
A poster in the Sager/Clevo subforum here tested 1600 mhz ram with the 2670 and it worked: http://forum.notebookreview.com/sag...r-np8130-clevo-p151hm1-owners-lounge-440.html

And I believe there were some posters in the Alienware subforums that got 1866 mhz ram to work with the 2630qm.

If your laptop uses the hm65 chipset, you must use plug and play (PnP) ram to run at greater than 1333 mhz ram, as this chipset does not support overclocking ram. However, if your laptop uses the hm67 chipset, you can overclock the ram through the bios.

 

I know faster rated DDR3 RAM sticks like the 1600 and 1866mhz modules will work with the older i7's like the 2630, but they are clocked down to 1333mhz from what Ive been told by a few sources.

 

2630 works for sure

 

Then they either do not have the hm65/hm67 chipsets, or are not using PnP ram. My guess is the latter. Just look at the pictures in the top two links I provided. Ram is clearly running at the rated frequencies.

Edit:

In case you are too lazy to scroll through the threads:

To read CPU-Z, multiply the frequencies by 2 to get the advertised frequency of the ram.

 

All Sandy Bridge CPUs support up to 1866 MHz RAM through XMP profiles or PnP modules. The reason why Intel have not included the complete support list of RAM is because 1866 are not official specifications from JEDEC. 1600 was recently (4-5 months ago or something) approved I think.

 

Yes, but the hm65 chipset cannot overclock the ram, so XMP ram would stay at 1333 mhz with this chipset.

 

Nope that is wrong. We have many users from this forum using 1866 RAM in setups that only supported up to 1333. Search around and you will find. You have to enable XMP 2 or else it will downclock

EDIT: I see that 1866 is also JEDEC now.

Are they using the hm65 chipset and xmp ram?

I know that pnp ram works with said chipset and any sandy bride cpu.

XMP relies on overclocking the ram, which the hm65 chipset does not support.

 

Yes people are using HM65 with 1866 and 1600 RAM. Search and you will find. It works. Don`t know where you have heard that it doesn`t because that is wrong. Im off to drink some champagne. Happy new year

EDIT: Here is proof. Its a review. kthx bye

I don't think you understand, you cannot change profiles if your chipset/bios does not allow for it.

In that article, they are using pnp ram.

 

I think it's i5-2520M and beyond even then it's hit or miss with most DDR3-1600 sodimm memory with the exception of Kingston HyperX PnP modules which seem to work with all CPU/chipset/motherboard configurations again i5-2520M and beyond.

 

AH. Now I see what youre talking about. LOL
Yeah you are right. XMP doesn`t work with HM65 like you say. Only seen people using PnP. Sorry about the misunderstanding.

Now dear champagne, I missed you. bye people

EDIT: I gotta stop editing my posts lol

 

Whats the difference between PnP and XMP?

 

PnP ram automatically runs at the rated frequency. XMP ram runs at various frequencies that you set through the bios, but not all laptops allow you to change the ram frequency.

am runing 2820QM with kingston 1866
run this in cmd : winsat mem and tell me your memory performance thnx

 

With the 2630qm and 1333mhz ram I get 17.5k mb/s. I was thinking about upgrading to the 1600 or even 1866 mhz ram, but I don't think the price increase justifies the minor performance increase.

 

Please go to cmd and run winsat mem.
I want to know how minor difference it is
thank you

 

Just ran winsat mem and got 10996.11MB/s.

I have a 2630qm and 1333mhz ram (1x 2gb and 1x 4gb, total 6gb).

 

23167.7MB/sec out of my Hyper-X

 

Ah someone get it what i wanted
Thank you guys
mine score is : 24085.57 MB/s runing kingston pnp 1866 along with 2820QM

 

And yet the difference between 1866 and 1333MHz are super minimal

 

what do u mean minimal??
moral hazard has over 10000 and that's more than half less of mine score ..

 

Some people still believe that real life difference between 1333 and faster RAM like 1600 or 1866 which may also have lesser latency in nanoseconds doesn't exist. Why they do believe it? I remember that many people in my country told the same about 1-st gen I-core Cpus. Then the same about 2-nd gen I-core Cpus. They were just envy.

Nowadays some of people have jealousy about this.
Other just do not want to believe in it because they payed a lot $$ just for recently top end Ram 1333 Mhz.
Some really believe that difference is neglible considering its higher cost.
Etc...

I just know that people who buy faster RAM really see the difference. The say about faster responce, faster windows switching etc. Just faster. I suggest some people buy this fast Ram and in a month go back to their stock 1333. I bet half of them won't sell faster RAM and will put it back in machine.

@cloudfire I already saw that benches. But Games do not require faster RAM with that fast Gpus inside. I would likely to see it on a system which has average fps in about 20 fps with slow 1GB max Gpu. Or integrated one.
Also It is good for multitasking. Normal real life computer desn't do single RAM extract job and at the same time on such a fast machine. usually people have many other tasks while extracting smth otherwise why would they buy multitasking machine with 8GB of RAM????? Main reason is faster esponse while something big is in a background.

 

Double memory bandwith and neglible difference in real life applications with the Sandy Bridge memory scaling. That is what sucks

True, unless the price similar to DDR3-1333 or the CL is super low (Corsair Vengeance DDR3-1866 CL10) then the upgrade is hardly worth it and better used towards a SSD or Hybrid HDD.

I just got 8GB Corsair Vengeance DDR3-1600 for $5 more than the similar 8GB G. Skill DDR-1333 (10666 version) so it was a no brainier for me.

Yeah but this is just games but when u doing with graphics or video or photoshop working there must be fell that RAM is faster?

 

You won't be bottlenecked by your RAM in those cases. Your CPU will be the bottleneck, so regardless of how fast your RAM is, there won't be a difference.

 

Here is another one. It is a german review, but it is real world test and is highly valid. "Sekunden" means "Seconds" and "auswirkung des speichertaktes" means "impact of the memory clock"

See? Even the 1333 and 2133MHz don`t have much difference
