DDR3 1600 on P150HM b3

I just bought a Clevo P150HM from BytesAtWork with the following configuration:

2720QM
GTX 460M
Kingston HyperX 8 GB (2* 4Gb) SO-DDR3-1600 Kit KHX1600C9S3K2/8GX

In combination with the 2720QM cpu, using 1600Mhz DDR3 RAM should be possible, yet it is running on 1333Mhz with timings on 9. In the manual on the clevo website on page 264 it states that when using 1600Mhz DDR3 ram you can only use 2 sticks of 2Gb, which seems pretty awkward these days.

As you can see in the following screenshots the memory itself can run on 1333Mhz with timings on 7 or 1600Mhz with timings on 9.




I tried to run memset to see if I could change it, but it got the "not for this system" error, are there any alternatives?

Anyone else also has this problem of found a solution?

 

I was hoping myself that someone found the solution to this before my laptop arrived. I should be getting mine soon and will try tinkering around with it if someone doesn't definitively find the answer first.

 

This has come up before. Only two of the slots run at 1600mhz. You can theoretically do 2x4GB 1600mhz sticks for a total of 8GB, but as soon as you populate the other slots your RAM will be downclocked to a maximum of 1333mhz.

You can have either: 16GB at 1333mhz, OR 8GB at 1333mhz. You can of course, go slower, but those are the two best case scenarios.

 

I think he's aware that the design is for only two of the slots to run at 1600. The manual specifically states that this only works with 2GB modules, but I think he's trying to find a way around that, or if the manual was mistaken.

I've said before that I don't see how it would have supported 1600 in the first place since there is only one brand of 1600 DDR3 that I know of and you have to have XMP to run it @1600, which the P150HM does not have.

I was hoping like him that there would be a way found to manually adjust the speed and timings outside of the BIOS or with an upcoming BIOS update.

 

Right now I am using two slots of 4Gb each, I am aware that you can't use 4 slots.

Only allowing 2 times 2Gb of ram (instead of 2 times 4Gb which I use) would be fairly odd given the fact that we are moving up from 4Gb to 8Gb as default amount of memory for these kind of laptops.

 

Which two slots are you using? Would it make a difference? I believe the two under the keyboard are the primary ones.. Maybe only they support 1600?

 

No primary slots are the ones on the bottom not the ones under the keyboard.

 

Memory speed test for Sandy Bridge. I wouldn't bother with anything more than 1333 Mhz CL9 memory. The performance gain is so minimal that is not worth it at all.

 

This is sort of what I thought to begin with, so I'm glad you provided some good evidence. I think my only consolation for waiting for this memory to come in stock and ordering it is that I'll have some higher binned memory capable of higher speeds in case XMP is eventually supported. If not, I'll just hopefully have a better guarantee that it will run stable and cool.

 

The two sticks were behind the keyboard. I placed them in the primary spots but they still run on 1333Mhz with 9 timings.

I guess we'll have to wait for memset to support sandy bridge or a bios update.

 

Here is an update from Sager pertaining this:


Some Answers related to 1600MHz DDR3 Memory on Sager NP8170, NP8150, NP8130, NP5170, NP5160.

First I would like to provide the following information.

There are two type of DDR3 1600Mhz memory available on the market.
First one is the official 1600Mhz memory which it is profiled by JEDEC memory standards @ 1600MHz
Second version is profiled for Intel XMP @ 1600MHz. (overclocking friendly)

Intel Core i7-2720qm,2820qm,2920xm natively supports maximum 2peices of 1600HMz memory with JEDEC memory standards profile, which it will work on NP8170, NP8150, NP8130. With 2x DIMM max when paired with one of supported processor.

The 1600MHz using Intel XMP is only supported on Sager NP8170 when set to 1600MHz XMP using the Intel Extreme Tuning, and that you will be able to populate all 4 DIMM slots, and it may be paired with any processors. As the 1600MHz speed is achieved by the overclocking function.

At this time Sager is still waiting for more 1600Mhz JEDEC standard memory to be offered by different brands in order to complete our comparability testing and list, so that we can offer the memory option on our systems.


Thanks,

 

so 2x4gb will work? and which 2 slots support 1600mhz? thanks

 

I think think its already known that it can support 2x2gb of 1600 ram, I think what he's trying to say is, by using this Intel XMP ram that can overclock to 1600, it is possible to fill all 4 dims, perhaps up to 16gb depending on the size of the Intel XMP, 8gb if they are only 2gb sticks. So you can have 8 to 16 gb or 2 to 8gb of 1600 ram that will work on any processor via software overclocking.

Well only with the 8170 I guess.

 

@Justin, do we know what brand/company sells this JEDEC rated 1600 RAM? I'm not turning up much using the google machine. Obviously anyone who doesn't own an 8170 will be needing some of that if they want to achieve that speed/timing set. Thanks for any info you can provide.

 

Sager is still working on it, we should have answers soon.

 

Go to newegg.com and pull up all DDR3 1600 laptop RAM. Select any one of them and look under the "Details" tab for features. It will say either "JEDEC compliant" or "XMP ready." At least all the ones I looked at did ...

 

JEDEC compliant-

Newegg.com - Patriot Signature 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model PSD38G1600SK

 

does this mean that the kingston hyperx 8gb kit (KHX1600C9S3K2) also will work @ 1600mhz?

 

I can confirm that the 8gb hyper x 1600mhz ram kit (KHX1600C9S3K2/8G) runs at 1600mhz on my eurocom racer.

Make sure you don't get the KHX1600C9S3K2/8G x version!

 

Dang it all to heck! That wrong part # is exactly what I bought. At the time, I think it was the only thing available. I didn' t know what JEDEC was prior to all this, so that's a lesson worth $100.00 right? I wonder if Newegg or Kingston will let me RMA it.

 

Newegg should let you return it, though you'd have to pay shipping and maybe a restocking fee. If you didn't open the package, you might be able to talk them out of the restock fee if you explain that you just want to exchange it, but I would chat with, call, or e-mail them first.

 

I successfully got Newegg to give me a store credit for the return of the XMP memory. They were trying to shrug me off with their standard policy and then I politely pointed out to them that the incorrect memory's webpage does not and has never explained that the only way to achieve advertised speeds is through XMP Profile/overclocking. I also pointed out that at the time, this was the only memory available on the market rated at that speed. After an exchange or two of courteous e-mails I'll be mailing back the wrong memory for an e-mail gift card that will allow me to purchase the correct memory. I give Newegg a thumbs down on the initial problem, but a big thumbs up on the corrective action.

 

I agree. Reviews have recently appeared on the item listing warning potential buyers (I wrote one of them) - but at the time I bought mine there were no such indications. As of right now, Newegg still hasn't made any kind of notation about this issue, but with the current reviews there, the customer has ample warning.

 

So your XMP 1600MHz memory works fine? What is your BIOS and KBC/EC version?

Mine finally failed again yesterday, nine days after updating the BIOS.

 

Yea i did the same thing told newegg it was not a true 1600mhz ram by default and got a refund with free shipping back. But I wrote a guide how to get 1600mhz workin for sager a while back.

http://forum.notebookreview.com/sag...generation-core-i7-run-ram-1600mhz-speed.html

 

Just for the record,

BIOS: 1.01.05LS1
KBC/EC: 1.00.03

 

Well, for 8150s it doesn't matter because XMP simply isn't an option.
