HAHA told ya it was safe intel 2400 ddr3 ram specs :)

[blackened23]

The spec sheets are rivised from intel and were posted in augest.it clearly shows 2133 at 1.65 and your warranty is 100& intact using the dims they provided.

They also list 1600-1800 as supported and there are many articles online sayibg ivy will launch with native 2133 support.I got these specs off intel.com

I don't kbow what other proof you guys need that 1.65 is safe

Their latest data sheet covers all 2nd generation core I7 processors and clearly states 1.5v ram is required. Further, when someone working at intel tells us that 1.5V ram is required...I tend to believe it.

complete list of most recent datasheets:

What you posted earlier was a RAM compatibility list and not a product data sheet. Clearly there was an oversight on the RAM compatibility list.

Its freaking intels own xmp certification omg forget it I'm done.

If you buy the ram I showed you and click intel xtreme profile it runs at 1.65 volts and that ram is listed on the sheets I posted from intel.

2 mobths ago there was no 2133 official support and now there is.

How is that not an oversight if the processor data sheet itself says "requires 1.5 RAM"?? Why do intel employees state that SB should use 1.5V RAM? Too much conflicting information, hence why I think the ram compatibility list is an error.

If there's another plausible explanation, i'm sure everyone is all ears

I just called tech support and the guy said they just passed intels jdspec testing and tgose sticks are fulky supported and covered under warranty as long as the right mother board was used.

Go ahead and call them and ask for your self.

With the 2nd generation Intel® Core™ processors like the Intel Core i5-2500K and Intel Core i7-2600K if you use memory at 1.65v you can damage the processor and void the warranty. Back in May I was asked about running memory at 1.65v on the 2nd generation processors and was told that doing so is pushing the tolerance on the memory controller and can damage the processor and void the warranty. The engineer say if you already have memory running at 1.65v as soon as you turn the system on, to go into the Bios and change the setting to 1.5v (which most good memory should have multiple profiles allow it to run at the lower voltage). If you are buying new RAM stay away from anything higher than the 1.5v. I know of 2 cases where someone has run their memory above 1.5v and damaged the processor and tech support has stated that their warranty is void because they are running out of spec.
In the end save yourself the headache; just pick up memory at the supported voltage.

This is what pisses me off about my Asus maximus iv extreme-z mobo.

My ram is 1.5V ram. All the spd settings, including the xmp profile, specify 1.5V. The socket is LGA1155, nothing is going in this thing except for a SB 2nd-gen core product.

And yet ASUS has the bios setup (most recent ver, 403) to automatically overvolt the ram to 1.65V D: until such time that I go in and manually change it to 1.5V.

Is my warranty void? Yes, according to Intel employee Christian Wood above, my warranty has been invalidated because of Asus.

You would think two moderately large companies like Intel and Asus would have their internal programs aligned well enough such that the customer is not exposed to this sort of "whoops, that's interesting, oh well, sucks to be you" customer facing policy.

Just did and they said that I have to use 1.5V ram..as far as I know intel hasn't released a new processor i7 stepping that officially has different IMC specs. And there's the whole datasheet issue as well. Do you have anything more substantial to verify this?

Anyway, my asus board also applies incorrect RAM voltage settings when its auto tuned. The XMP profile for my RAM is 1.5V yet there's an error on numerous asus boards that will apply incorrect voltage using the auto tuning tool. I've mentioned this to asus tech support (who are generally worthless) and they mentioned they are aware of the issue and looking into it.

okay IF they just changed it then how does that make previous advice I was giving to be crap? I was going by what we had officially been told and I can not predict the future. and what magically changed that 1.65 is no longer an issue even though 1.575 was considered to be safe max until now?

 

[grkM3]

Yeah sure did.call and say you have gskill f31700 rame and ask them if your board is supported.

He will ask your exact board and bios and then ask the exact numbers on the ram.

After a min or 2 he will say that ram is xmp supported for your setup.

The only possible way is if intel has a new i7/i5 processor stepping with a different IMC. As far as I know that is not the case.

Everything is pointing to an error on their ram compatibility list.

Well how does gskill have 2133 intel certified 1.65 xmp ram for sale right now on newegg and it specially says intel certified for sandy bridge cpu?

What your saying is the second you boot up with this certified ram you void your cpu warranty

 

[Idontcare]

I don't want to throw cold water on your parade, but you do need to be aware of the fact that Newegg, and its suppliers, have been caught out time and again with false advertising of the products they list.

The reality of Newegg is you really, sad as this is, can't trust them to give you the correct specs and info on the products they are selling.

Doesn't make it right, doesn't justify that they do it, but it is the reality of the situation.

So before you go an burn up your 2600K using dimms that are advertised on newegg as being compatible, albeit at 1.65V, you really should contact Intel and confirm since it is Intel who is going to refuse your warranty coverage should you burn up your CPU and then you tell them "but but but I was using 1.65V dimms advertised somewhere on teh intarwebz as being sandy-bridge compatible!".

They will tell you tough sh!t, they aren't responsible for misguided specs, and you will then be left with a dead cpu and trying to argue with Gskill or Newegg that they are responsible for replacing it. That's when the epic lulz ensues.

What your saying is the second you boot up with this certified ram you void your cpu warranty

Actually it is Intel that is saying that. They even said it here in these forums via their customer rep.

 

[grkM3]

Well its a huge coincidence that intel put that very same model number that gskill says is supported on there web site.

you guys can make your own choices of weather its safe or not.

Why do you keep linking that same document. Its nothing more than a RAM compatibilty list that apparently has an error on it.

Did the 2nd generation i7's get a new stepping that have a different IMC? No.

Does their datasheet for all 2nd gen i7 processors indicate that it reqiures 1.5V ram? yes

Has 1.5V ram been standard for the Lynnfield/SB CPU's since their inception? Yes

Is the only way around this a change in the CPU itself? yes.

If you're trying to prove that I7's suddenly overnight decided that they can now use something other than 1.5V ram for their specification, you'll have to find something more substantial. I'll also point out that intel engineers state that SB requires 1.5V ram, and that has been the standard voltage for DDR3 memory for a long time now.

At least we can agree that a change in the memory voltage requirement would require a change in the CPU itself....has that happened in the past week? Nothing against you but I don't think that document proves that SB can use 1.65V ram "officially" - considering all of the other official information out there it seems to be an error. All of the information from official channels indicate that 1.5V ram is still the requirement.

Get over the RAM compatibility list. Clearly its an oversight on intels part since intel has said since FOREVER that I7's require 1.5V ram. The only way that can change is if there's a new processor stepping with a different IMC.

its also on there i5 sandys list and its revised,you do know when we click on the profile thats programmed in the ram it says intel xmp right?


her is kingstons ces showing

Kingston used the Internet Consumer Electronics Show (CES) to announce that its 8GB 2133MHz HyperX memory kits have achieved XMP certification for the P67 Sandy Bridge platform.
The HyperX T1 8GB memory kits are the first to be validated for the platform. The kits were subjected to extensive testing using the Asus P8P67 PRO and Gigabyte GA-P67-UD4 motherboards in Kingston labs. Following success, Kingston submitted the memory to Intel. Intel posted the XMP certification results seen here.

"The new 8GB HyperX memory kits were designed to push the memory boundaries of the new P67 motherboards in both speed and capacity," said Mark Tekunoff, senior technology [Kingston.

"Our 2133MHz T1 modules featuring the signature tall heatspreaders passed the rigorous testing requirements both in-house and at Intel to achieve XMP certification. This is the perfect kit for enthusiasts who want to maximize from the new Sandy Bridge platform."

Why dont you really call intel tech support and ask if xmp 2133 is supported on p67 for your self

 

[blackened23]

Well here's where its gets interesting.

All of the 2133 kingtson RAM you linked on newegg were old products from 2009 , you know, back when 1.65V ram was acceptable on some platforms. Oddly enough, EVERY SINGLE one of those products have been discontinued and deactivated on newegg, with no intentions of being stocked again.

Why would you link a press release and then the corresponding products on newegg were discontinued 2009 products?

well heres a funny thing,I havnt linked one single kingston kit on newegg.I am only going by what I have and what I bought it for.

the 2 gskill kits I posted are listed with sandy xmp support and are on 2 different intel pages showing on an I7 2600 setup and an I5 setup and also show many other ram kits that are supported for sandy bridge going from 1600,1800,2000 and even up to 2200 xmp.

kingston was brought up becasue they were the first to push intel to support there speeds.

in a few weeks you will see more kits that say xmp 2133 and all the older kits worked but didnt have official compatibilty from intel using them.

 

[RussianSensation]

and 1333 and 1600 memory has been 50 and 40 bucks so whats your point. you are still paying twice the price for nothing in return as for as real world gaming goes.

Exactly. He runs AID64 Memory Bandwidth all day to make him feel good about his chest thumping DDR3-2133.

I guess my chest thumping 2133 kit will last a while huh toyota,maybe even as long as my moms toyota camrey

Oh really? DDR4 is likely to arrive in 2-3 years, at the most.

And then in 5-10 years, RAM up to 10x faster: http://www.nordichardware.com/news/...es-faster-ram-with-new-micron-technology.html

Oh noes! Your "DDR3-2133mhz RAM" $200+ kit futureproofing is questionable since future systems will either move to even lower voltage DDR3 OR ditch it completely in favour of DDR4. Future proofing with RAM is a joke since it practically makes no difference in performance (i.e., those funds are far better invested into the CPU/GPU/SSD).

It's also one of the few components that has been dropping in price for the last 5 years without any sign of slowdown. In 5 months I bet we'll be able to buy a 16GB kit for $60 with rebates.

 

[blackened23]

Exactly.


Better not showing him this then:

http://www.nordichardware.com/news/...es-faster-ram-with-new-micron-technology.html

Oh no! His DDR3-2133mhz RAM is going to be obsolete.

Not only that, but DDR4 is likely to arrive in 2-3 years at the most.

Future proofing with RAM is a joke. It's one of the few components that has been dropping in price for the last 10 years without any sign of slowdown. In 2 years we'll be able to buy a 16GB kit for $60 I bet.

The worst future proofing i've ever done was with rambus ram back in the day.

WHAT was I thinking.

As far as the topic at hand, i'm still not convinced but i'll give it a few weeks for the dust to settle. There's still a lot of conflicting information on this....and I don't see how 1.65V is suddenly in specs when it hasn't been since the launch of lynnfield/SB. Unless there's a new CPU stepping or something.

 

[StrangerGuy]

I'm would be especially proud if I paid extra ~$300 for a mobo and DDR2133 with no real world increases to speak off. That's like buying a GTX 570 only that you don't get to use it!

 

[TakeNoPrisoners]

1.65V ram is not safe with sandy bridge. End of story.

 

[sangyup81]

OP, you'll need at least a second, if not a third example to be convincing here. 1 example does not eliminate the possibility of a mistake on Intel's web team

 

[grkM3]

I called intel tech support,what more do you want?

What does future proofing have anything do with with this?

Who cares when ddr4 comes out,intel is going quad channel ddr3 next year and you people should be happy these will work on socket 2011

ohh I paid 40 bucks more than you did for my ram,omg I blew so much money away for nothing.

 

[grkM3]

OP, you'll need at least a second, if not a third example to be convincing here. 1 example does not eliminate the possibility of a mistake on Intel's web team

I gave you many examples

1 gskill says there ram is intel xmp ceritified for sandy

2 intel shows that ram as certified

3 kingston says it passed intel xmp for sandy

4 I called tech support and asked

5 intel has another spec sheet showing i5s supporting ddr 1600,1800 and 2133 all at 1.65 volts and even lists p67 and z68 boards and bios that support that ram.

Its pretty hard for intel to screw up the whole freaking spec sheet across the board and list bios and boards that support those speeds and even say rivised august compatibilty list.

when you put one of these sticks in and pick the intel xmp profile(something that intel certifies)why is there an option for it on a p67 board?

that xmp has to pass intel certification and all up until now they didnt have that cert and we were just using overclocking ram at are own risk.

here go on intel and see for your self.

http://www.intel.com/content/www/us/en/gaming/gaming-computers/intel-extreme-memory-profile-xmp.html

click the i5 and the i7s and see for your self.the list part numbers and boards with even bios versions.

 

[notty22]

My take on this, I read many launch reviews that mentioned this issue/specification. They said they saw no trouble in running 1.65v ram. Discussed this with their Intel contacts.
They also recommended if buying new ram, buy 1.5v ram. Here is where common sense has to come in. At first it was hard to get 1.5v 1066 ram, now its not. Its now common throughout the market to get 1600 kits at 1.5v. If you want to run ram at o/c speeds than Intel suggests, eventually it requires more voltage.
IMO, they just don't want people to start over-volting ,while over-clocking , taking 1.65 to the next level. There really might not be another 10% wiggle room , without hurting things.

Here are some of those original threads.

http://forums.overclockers.co.uk/showthread.php?t=18227652
Memory - Intel recommend 1.50v plus/minus 5% which means 1.60v is the ideal safe maximum, but we have found in our testing all 1.65v memory is fine. We have also found most new 1.65v like Corsair XMS3 will run at its rated timings with just 1.50-1.55v which is well within Intel specifications. So people upgrading to Sandybridge you can still use your old DDR3, but we do recommend you run it at 1.60v or less. We are shipping most of our bundles which feature Corsair XMS at 1.50v-1.55v at rated timings. We've also discussed with Asus and MSI regarding voltages for memory and they also confirm in their testing 1.65v caused no issues with reliability.
