RAM for X505-Q894

Hi all.

I notice that Crucial.com has 2 options to upgrade the memory to 8GB.

The option for $108 lists these specs:
Part #: CT1587099 • DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.5V • 512Meg x 64

The option for $116 lists these specs:
Part #: CT1587107 • DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.5V • 512Meg x 64

The only differences I see are in bold. Is the more expensive option any faster?

Thank you much!

 

This is what Toshiba uses for the Qosmios (same as option 2 for $116).

Good luck!

 

Thanks, but do you know if one is faster than the other? I really don't know the difference between
PC3-10600 vs. PC3-8500 or
DDR3-1333 vs. DDR3-1066

I'm scanning through the documentation to figure something else out -- does this laptop have only one internal hard drive bay? (I do not yet have this laptop).

Thank you!

 

SInce your replacing your current ram, you can get the 1333 ram, which is faster; but I wouldn't mix and match 1066 with 1333.

I've read that the i7 can support 1333 ram but the i5 cannot. If the 894(i7 chip) happens to not support 1333 then it should under-clock to 1066 anyways.

Good luck and let us know what you decide and give us updates after you upgrade.

 

Ok, thanks Alex.

I won't have the laptop for another week or so. Just getting ready.

 

Here is the ram I am using in my Q896 and it runs 1333 9-9-9 1T. I don't think the i7's are terribly picky with ram as long as it is nothing exotic.

As to which is faster, 1333 or 1066, that is a good question. The 1066 is typically slower but has tighter timings, 7-7-7 while the 1333 is faster with looser timings, 9-9-9. I need to test this but my theory is the 1333 will have a slight advantage but nothing major since the timings are looser.

 

Can you prove this by screen shots please? I ordered my q896 today and I am looking into 1333mhz ram.. if this motherboards version of the i7 supports 1333.. I dont see why it should'nt. Thanks!

 

Here you go.

 

i believe the i7 processor qosmios can use the 1333mhz, i called toshiba and they said that they couldnt use the higher clocked speed ram, however i ordered the 1066mhz and the company accidently sent me the 1333mhz and it runs it fine. so toshiba doesnt know what they are talking about.

the speed should be noticeable 1333mhz over 1066mhz

 

Awesome. Is the PC's performance significantly faster now that you've doubled your RAM? Moderately faster?

Thank you.

 

I am sure that the Qosmios will run with the 1333 memory even if they are meant to use 1066, BUT the PC may be downclocking the memory speed to for the CPU and Mobo capabilities.

 

So, we'd never really see the benefit of 1333, correct?

 

imo doubling the ram is definitly worth it, as far as the windows expierence index i went from 7.3 to 7.4 going from 4gb 1066mhz to 8gb 1333mhz, however the snapiness of the computer is highly noticable. im running the i7 and 8gb nothing taxes the laptop at all. imo its definitly worth it

also i dont believe that the Cas and latency is being downclocked in my qosmio as im seeing 9-9-9-24 on my cpuz and if the modules were being downclocked you might see 7-7-7-24 cas latency out of 1333mhz to get 1066mhz. thats just my take.

i definitly think toshiba is underrating these qosmio laptops as far as the capability and the motherboard capability.

 

Glad to hear the good news. It will be my first to do upgrade on my list for sure.

 

That's ONLY IF the laptop can run on 1333 RAM but cannot fully utilize it. I could be wrong. I was just offering a possible explanation for why Toshiba said that the PC would not run 1333 RAM and it worked fine for mooses9. In short, either the tech support person that he spoke to was clueless or the laptop can run with that memory only at a downgraded speed and mooses misunderstood the tech.

 

specifically the tech told me if i put 1333mhz memory modules in my dimm's that it would throw a error and would not work with my motherboard. becuase see i bought 8gb of 1066mhz memory and i was wanting to upgrade to 1333mhz and i called toshiba to see weather or not it would work, when i called thats what they said.

it turned out that the memory that they sent me was already 1333mhz running at 9-9-9-24 which was a nice suprise. so the laptop isnt downgrading the memory to run 1066mhz, but is running 1333mhz.

 

Well, that clears that up, mooses, thanks for the information!

 

Yes, thank you! Great news.

 

yeah no problem. they definitly seem to be trying to underrate the capabilities of the older qosmio's, maybe to upplay the newer sandy bridge qosmios that come with 1333mhz from the factory.

 

I just ordered 8gb of 1333 for my qosmio q900s. Didn't receive it yet but if you want to see what speed your memory is running at download the free version of sissoft sandra. If you look under mainboard and scroll to logical/chipset memory banks it will tell you the current memory speed and also the maximum speed of the memory bus which says 2x 667mhz which is 1333 so it should work. Will let you know in 2 days when it arrives.

update:


Now I am really bummed, I knew I should have waited, Qosmio X500-Q930S with Sandy Bridge is now available with 8GB of 1333 for less than what I paid. One good thing though, in the download section for the Q930S there is a newer nvidia driver for the 460m that finally worked. The nvidia driver from Nvidia website will not install on this model.

 

Can you link the ram you got exactly? also.. Lee are you upset about we spent all this money for these laptops and now the sandbridge processors are coming out? lol

 

Don't be too mad (as I just got mine 12/20/10). The Sandy Bridge counterparts will cost MORE than if you were to buy a comparable model today. My 894 cost $1400, but the Sandy Bridge equivalent will cost $1600.

 

kk.. well I just got mine 12/31 lol q896

 

I have the Q892 with an intel i5, will the 1333mhz RAM work on mine? I want to boost the minimum frames per second to get smoother graphics on Battlefield Bad Company 2, would this be a smart investment to accomplish this?

 

I just got it from Crucial.

Computer memory upgrades for Toshiba Qosmio X500-Q900S Laptop/Notebook from Crucial.com

You can use their memory selector tool to find the specific part for the other Qosmio's. I will post if it works after I receive the ram tomorrow.

 

The Sandy Bridge Q930S is 1899, I paid 1999 for the Q900S in November

 

Ya, there's some trade offs. Yours came with windows 7 professional (couple hundred more).

 

you can also use cpu-z to check the memory latency configuration along with the speed.

 

Results are in and my new memory does indeed run at 1333mhz according to sissoft sandra, SIW and CPU-Z. Experience index went from 7.2 to 7.4 for the memory. Don't know why Toshiba told someone here it would not work but their tech support was always iffy at best. I love Toshiba laptops, this is my third but it should have come with 1333 memory from the factory. Sisoft sandra also says max installable memory is 32 gig while SIW reports 16 gig max any volunteers?

 

my thought is that the older models came with 1066mhz instead of 1333mhz so the new ones could come out with 1333mhz chips, i donno maybe im wrong, but it seems like they were trying to bs me about the motherboard not being able to support 1333mhz, maybe in hopes it would get ppl to buy the newer sandybridge qosmios? i donno
