Vaio Z memory speed diff from i5-520 to i5-540/i7-620?

Hi, Gang!

I told you they were cool! Cindy Tsan from EWiz was kind enough to answer my email, and they've provided an alternative for us! For those who want to buy more than one of these Samsung modules from EWiz, they have a second listing of the exact same module, which does not have the one module/person limitation. It's $10.86 more for the second module, but this still makes this the most cost-effective solution that I'm aware of. Thank you very much, EWiz!

Here it is!

Cheers!

Howdy!

Something's a little wonky with EWiz's website. If you wind up seeing a URL which ends in CJ, try changing the CJ to PW, and you should see the no limit/person webpage. It's strange, because I'm explicitly referencing the PW webpage in the source code here.

Cheers!

Well, I did it. I pulled the trigger on the 4GB of Samsung from ewiz last week. So I got it today, plugged it in.
As I type this I am reigning lord and master of over 8 beeelion bytes of ddr3 random access memory.

 

Hi, Oscar2!

Excellent! I'm glad that it's working out for you. It's great to hear that someone's actually moved ahead with this... besides just me!

Have Fun!

Sorry, not trying to get off topic but I noticed the memory question and you all seem to be knowledgeable so maybe you can help me out?

Just got my 1647 set up (replacement for my 1640) and got sent an additional 4gb dimm and popped it in for a total of 8 gigs. i7 620m with 8gigs ddr3-1066 (specs in sig)

CPU-Z shows 8 gigs, everything works fine..The Memory tab is blank so it doesn't show what its actually running at or its timings or dual channel mode or not...Which caused me to think it wasn't running in dual channel mode..So I got everest ultimate edition and it indeed showed it was working in dual channel so I was happy..But then I noticed it reported the memory was running at 100mhz and in ddr3 terms that effectively is 800mhz...The ram should be running at a base clock of 133mhz or 1066mhz effectively. All the tabs report it as being rated at 1066 and all that registers fine..Its just the "actual clock" reports it at 100mhz instead of 133..

I thought back to the 4gb dimm I recieved..It was refurbished which made me think it was the culprit..So I did some tests. I tested each dimm individually by themselves and each time (alone and together) everest reported 100mhz (800mhz)..

So is everest to be trusted? Are both my dimms bad? Whats causing my dimms to run at 800mhz instead of 1066? There is nothing in bios to tweak so how can I change this? And let me repeat, both dimms, when installed BY THEMSELVES (so 4gb total) still report 100mhz...so it cant be the refurb dimm...one dimm is hynix one is samsung. And again I ran them each by themselves and got the same results:

CPU-Z screenshot..



Everest CPUid: (notice ram clock)



What gives??

My window index score on memory is 6.8..which is about what it was on my last machine which used the same speed ram..Bios report ram is 1066 (I dunno if thats actual speed or whats its 'rating' is)

Could everest be wrong? I ask because its a new chip, the memory controller is now integrated into the gpu which is off die and no longer on the same chip..

 

How did you get a 1647 as a replacement?

 

You haven't been following all the replacement threads on the Dell XPS forum have you?

I wrote a letter complaining about my throttling. Went from a 1640 t9800 4gigs of ram to a 1647 i7 620m 8 gigs of ram.

 

Hi, Tenknics,

No, most of us in the Sony forum aren't following Dell threads. I notice that you've also been posting in the wrong forums on other boards, too. I mean, it would have been really helpful if you'd at least have identified the manufacturer of the machine in your initial thread, instead of expecting us to intuit it.

Anyway, to try to help anyway, please download SiSoft Sandra 16.26. After it's installed, fire it up, click on the Benchmarks tab, and run the Memory Bandwidth test. Here' I'm only running on an i5-540, so my results should be lower than yours. I see bandwidths of 9.344 GB/s and 9.295 GB/s. Please let us know what you see.

Regards,
Mark

 

mjflash what are you talking about? What initial thread? You mean post? What does the manufacturer of my laptop have anything to do with my ram? Its not relevant to the question I was asking and doesn't have any effect on what I was talking about. All the mobile i5/i7s use the same exact chipsets, its a moot point. Also anyway capable of taking the time to read and ridicule can see all the relevant specs in my sig, including manufacturer.

And again if you were really paying attention, the person before me posted a question regarding about how I was able to get a 1647 as a replacement.

He owns a 1640, which is a Dell...hence the question about him not following the 1640 replacement threads. I would not expect people in this thread to follow Dell threads, but since he owns the same machine I did, it was pretty logical between him and I to ask that question..I don't believe that question was directed at you or anyone else in this thread..thanks though! Are you a moderator? What are you getting at? I have no idea what you are talking about as far as me posting in the wrong threads, but I have not done so. Are you like stalking me or something? I asked a memory question in this thread because it related to the topic, everyone was talking about memory and core i7s. I purposely didn't bring up Dell because it wasn't relevant... we all have the same chipset and memory specs...Anything else?

 

That dude sure has an awful lot of attitude. I say ignore him and maybe he'll go away.

He answered jcomey as if he were mjflash. As far as stalking goes, it's a super simple matter to click on someone's name and notice that their posts tend to be misplaced. Thirdly, mjflash gave him the gentlelest and most deserved of chidings followed by genuine assisance and he comes back with huge attitude. (it was deserved because he comes in here talking about 1647 like we are supposed to care about what a p.o.s. a 1647 is).

Someone should tell that dude to re-read mjflash's post and to re-asses whether all that bad attitude is called for. (and then someone should politely ask that guy to go away)

 

Hi, Folks!

Tenknics: Stalking you? Not quite. To save yourself five letters of typing, you decided to send those who might wish to help you on our own Google search to find out what a "1647" or a "1640" are. Guess what popped up? Your own post on XtremeSystems. You'll notice that you were chided there, as well, for posting your question in the wrong forum. FYI!

Oscar2: You're a gent - thank you very much!

Cheers!
Mark

 

He said on other boards my friend, not this one. And if you clicked on any of my posts you can see they are all in the correct and relevant threads. Please read what I write before you comment, I never asked anyone to care about my 1647. I asked a memory question, and he told me mention manufactures name, not me. Thanks for coming out though!

 

Oh and Fyi, since you seem to be following me so closely, did you also notice the thread I started over there wasn't closed and in the end I was right to post it in that forum? Do you also know the person who originally "chided" me sent me a PM saying he was wrong? no, you didn't...Because you can't google that. I asked a question about memory timings, speed and bandwidth, and it was posted in the GASP, bandwidth forum. Thanks for coming out though!

You have too much time on your hands, googling posts by me? I asked a question about MEMORY. Way to take this entirely too far. Get off your horse man, sheeesh. I never once asked anyone to google anything about a 1647 or a 1640. Why do you keep saying I made people do something when I didn't...Maybe if I re-post what I said you and your followers will read it this time.

Yea I re-read what I said a few times...I dont see anywhere in there where I asked anyone to google what a 1647 is nor did I see where I told anyone to care about my 1647. I can take this further and spell out the logic in posting that post in this thread if you like?

You see this thread is called "Vaio Z memory speed diff from i5-520 to i5-540/i7-620. As I said, I have an i7 620m which also uses the same ram speed as others in this thread.. How do I know that? Well because we all have the same cpus and these cpus can only run in one chipset currently and all the chipsets, REGARDLESS of laptop brand, still function the same way. So if someone had the same hardware as me, and I am curious about an issues or a problem I am having, wouldnt you think it's logical that I asked that person for help? I do and I'm sure most would agree.


I like how you totally turned this from me asking about a memory question to me trying to make everyone care about a 1647. This is hilarious!

Oscar, I'm sure glad you think my 1647 is a POS. Did me asking a memory question in a sony thread even though I have a Dell make you upset? I'm sorry that I don't own a sony like you Really glad I came to this thread to seek an answer on a memory problem I was having. It looks like those only with Sony laptops are welcome here, even though we have the same exact hardware underneath! hahah, irony. How dare I own a Dell laptop and ask a question to someone who owns a sony! Can you ever forgive me?

 

Tenknics: The nature of the system being tested is extremely relevant to any answers I could give you regarding performance. For example, some desktop configurations will show nearly a 2X difference in memory bandwidth compared to notebooks. OK, I'm sorry that I've been unable to, and won't be able to, help you.

Mark

 

tenknics,

You really must slow down and relax. Your responses have proven adept at making mountains out of mole hills, but you must realize that such disproportionate responses will not serve your cause.

To be fair, you are in a Sony-specific forum in a thread titled for the Z, and despite the fact that this may use the same hardware as other computers in existence, owners in brand/model specific areas are often annoyed by "intruding brand" posts. I'm sure there are Dell and/or generic forums more appropriate for such questions, where hostility, condescension and sarcasm need not be in your required conversation tools.

 

I completely agree to disagree with you. You don't seem to know what you are talking about or at least what I am. You say some desktop configurations will show 2x performance of laptops, well of course they will. One is a desktop and one is a laptop. Im talking about IDENTICAL hardware, in this case ours is IDENTICAL. Laptops aren't nearly as powerful as desktops and the hardware isnt even close to be identical, of course they will be more powerful..

 

Tenknics: I'm trying to communicate that I had to search for what hardware you have in order to be able to recognize whether it was similar to, or radically different, from what I have. Sigh. OK:

/ignore Tenknics ON.

 

Howdy, Folks!

OK! After a solid week of additional testing, this setup continues to work flawlessly. For completeness' sake, I swapped the SO-DIMMs around, and performance is identical, while Sandra continues to report that the RAMs are running at the same DDR3-1066 that the modules claim as their 533 MHz (DDR3-1066) capability. These really are great alternatives for Vaio Z owners who wish to expand their memory!

Cheers!

specs are in my signature, which I referenced many a time and in the original post I referenced that I had a i7 620m with 8 gigs of ram.With any i5-520 to i5-540/i7-620, we all use the same chipset and memory type DDR3, so there was no looking up to be done. That was your own fault. Thanks for reading.

 

Just let any with US new Z CTO owners know that the Sony put DDR3 1333MHz Samsung memory to its new Z CTO. If you try to upgrade from 4GB to 8GB, make sure you order the right chip.

Sony VPCZ119GX i5 540m 4GB HD 128GB

 

So tenknics,

Did you ever figure out your deal on the 1066 memory with Everest reporting 100MHz?

I downloaded Everest and, if you are talking about Motherboard | Motherboard | Memory Bus Properties. I notice that mine shows 100MHz whereas the front side bus shows 133MHz

 

It is 1333MHz DIMM but it works in 1066MHz mode so any PC3-8500 DIMM will do . I paired it with Hynix PC3-8500 (1066MHz) 4GB DIMM.

 

I installed the Super Talent DDR3-1333 DIMM (Samsung chip) 4GB DRAM to my new Z. The Win 7 boost the performance index from 5.9 to 6.4. I found that CPU-Z showed the core bus speed is 1333 MHz. The magic of the extra 4GB DRAM pops all of my applications up with lighting speed. The Windows 7 Performance index of my i5 540m also increase to 6.8, which is almost very close to i7. I bought this memory around $177 (include tax and shipping) from SuperBiiz.com (Ewiiz.com). I strongly suggest that anyone has 4GB only with the new Z baby, he or she should invest additional 4GB DRAM.

MJFlash, Thank you for the information.

 

@TheLastOracle
Don't want to spoil anything but I have 6.8 for both memory and processor with 1066 Hynix RAM and i5-540. Also, for CPU, core frequency 1333MHz just means that it currently runs at multiplier 10. That has no relation to memory frequency/speed.

 

Thanks for the information. Frankly speaking, I am not a PC guru. The reason that I pick the 1333MHz chip, is I don't want to mis-pair the 1066 and 1333 chips in a new system.

May ask questions? What is the maximum bus speed for the i5? What is the Z11 maximum speed from memory channels?

 

Intel i5/i7 specs state RAM bus speeds 800 and 1066. Does not mean that future steppings (modifications) would not support higher RAM speeds. Z's CPU is not upgradeable though. But, indeed, your 1333 RAM has a better value as it can be put in future laptops supporting 1333 RAM.

 

I dunno if anyone tried - but when "Advanced" menu is unlocked in the BIOS setup, there is an option to set the memory speed to 1333 MHz

By default it is set to 1066 MHz (of course)

I cannot try this as German CTO Z comes with 1066 MHz memory, but who knows maybe it is an overclocking option that still works, even if chipset was not explicitly validated for it.

Of course, on the other hand, setting this might make notebook unbootable... so beware.
