Sony :: Vaio Z Memory Speed Diff From I5-520 To I5-540/i7-620?
Mar 26, 2010
While eagerly scouting the Zs, I've greatly enjoyed this forum for the past few weeks. I've been stopping by (ok stalking) my local Sony Style store to check them out in person, and became curious about a discrepancy.
Does anyone know off hand if there is an inherent memory speed or bandwidth difference between the 520m and 540m (or 620m)? I haven't noticed anything official from Intel or the Sony specs, other than they all use DDR3/1066 sticks.
Last week I snapped a picture (rather fuzzy cellphone, sorry) of the WEI screen for the lone silver GX/S (i5-520m) floor model. It shows a lagging score of 5.9 on memory, which doesn't jive with other performance scores mentioned on this forum (that I could find).....
Ive had a vaio Z 2.53Ghz for a few months working very well. Lately Ive been noticing that the system feels really slow. I just ran a CPUZ and got the readings that the CPU is operating at 1/2 speed (around 1.26Ghz). I ran a few benchmarks (SySoft Sandra/Everest) and was confirmed again that the system is running at 1/2 speed. I remember that runnig on batteries usually the CPU slows (lower CPU multiplier) down to conserve batteries but mine is plugged-in and it does not make any difference. I opened it up and took out the CMOS battery for a few seconds to re-set the BIOS to see if that would fix it. Same problem.
Also I noticed that my power settings Tab incontrol panel are all grayed out so I cannot change or access them... this is all so weird... I know that setting power settings in XP's to the maximum performance profile, turn off Intel SpeedStep which is what I suppose is forcing my system to permanently using a lower multiplier...
I've just purchased a VAIO CW2 (VPCCW2S1E) and did a format and fresh install of Windows 7 x64 to rid myself of all the bloatware. The problem is that copying to, from and between external USB flash/harddrives is now extremely slow - often a couple of hundred kb/s, and sometimes 2-3 Mb/s, when the speed should be 20 Mb/s+. I've had the drives for a while and they work flawlessly over USB 2.0 with other computers. I know that USB copying speed was normal before the format as I copied the Windowsdrivers folder to a USB harddrive, though that folder was only a few hundred Mb.
I assume I missed installing some USB chipset driver after the format, though I have installed the following:
1. IPS_Driver_1.0_10Q1_O_188.8.131.520 (unsure what this is)
3. SFEP_Driver_Sony_8.0_10Q1_O_7_184.108.40.206 (unsure what this is)
The list of available drivers is here: [url]
I've installed Windows 7 on a fair number of computers and never had this problem; how typical then that it should happen on my own laptop
It seems for some reason my Z690 does not work well in the speed setting. This results into videos that seem to refresh a lot, games that are slow and have jagged edges and in general slow video performance.
Whats funny is that on stamina setting, all my graphics actually do quite well. Videos play fine as do the games /w smooth edges
I have a Sony Vaio VGN-Z590 with windows 7 32 bit professional installed. When I switch to speed mode and hook up a monitor (24" dell LCD) via HDMI->DVI the graphics card temperature goes up to around 80-95C (measured with real temp 3.40) and the CPU temp also goes up into the 60-70s. No programs are using the CPU heavily. During this process the fans go up to max and the computer gets really loud. I have all the latest drivers installed and the latest BIOS.
I was wondering if anyone else has a problem like this? Would installing 64 bit windows 7 be better? It makes it really noisy when I hook up a monitor via HDMI. Any ideas?
Everything is perfect in stamina mode, low temps, low cpu usage.
Does anyone know what the speed is of the iLink port on the new Sony Vaio Z Series Core I7?
I'm trying to decide whether to get the Vaio Z with 3 usb ports or 2 usb ports and 1 iLink port. If the iLink port is a lot faster then the usb ports i'll probably get it with an ilink port. If it's a slow ilink port (400 mbps) then i'll probably get the laptop with 3 usb ports.
It would be nice if it comes with a fast ilink port (800mbps) so i can get a faster connection if i connect the laptop to an external hard drive.
just can't seem to get my Brightness controls to work in speed mode in windows 7.
I've tried 169.09, 180.70 and the most recent forceware drivers.
I've installed the registry file that was recommended in one thread. I've tried all kinds of orders. Still, nothing.
I've currently installed (in this order) SPEF SonyPI Shared Library SonyUtils DLL Event Service The Registry Patch NVIDIA Drivers
They work fine in STAMINA, but not in SPEED. I can't even access them through Windows Mobility Center or Power Options. I can change them a very small amount though the NVIDIA control panel through the "adjust color settings" tab. Otherwise, theres no mobility options in the NVIDIA panel.
I have had some strange things happen on my Sony Vaio SZ.
I returned from holiday (two days away) and brought my SZ back up from hibernation mode. It hung after I logged in. Rebooted it, and it came back after I put the battery back in and disabled wifi. Not that these actions indicate a problem with either wifi nor the battery (which died back in 2006).
However, it is running rather slowly. I installed the benchmark programme called Performance Test, ( http://www.passmark.com/products/pt.htm ) from an Australian company. It informed me that the T2600 (2.16Ghz) was actually running at 1.006Ghz. On top of this it gave an overall performance rating of 276, which is extremely poor for a Vaio SZ.
The original Sony Windows XP installation was removed a long time ago and an OEM XP Pro and SP3 was installed with a selection of specific drivers for the Vaio SZ components.
I've just installed Windows 7 Ultimate 64bit on my Vaio Z11MNB. As Google told me there is a problem with the FN + F5/F6 brightness adjust in speed mode.
All Sony software ist installed correctly and in the newest version I found.
As in many threads mentioned I followed the right order. But I still cannot adjust the brightness in speed mode
This thread Problem with Vaio Z Windows 7 brightness lead me to the right graphic drivers I thougt... Okay these drivers[url] are for the ZD790 but this shouldn't matter it's the same 9300GS chipset...
The following sony software is installed: SETTING_UTILITY_SERIES_5.1_220.127.116.1100 SFEP_DRIVER_SONY_8.0_10Q1_O_7_18.104.22.168 SPIC_DRIVER_8.0_09Q3_7_22.214.171.124 SONY_SHARED_LIBRARY_5.5_126.96.36.19960 VAIO_CONTROL_CENTER_4.1_188.8.131.5260 VAIO_EVENT_SERVICE_5.1FH_184.108.40.20610 VAIO_POWER_MANAGEMENT_5.0_220.127.116.1100 VAIO_SMART_NETWORK_3.1_18.104.22.16850
Another smaller problem: From time to time there is a yellow exclamation mark at the SD-Hostcontroller in the device manager. I've googled a lot but there seems to be no other driver than the windows included. VEN_1180&DEV_0822
I have a VGNSZ645P3 Vaio which I got as xmas gift. I decided to Max out the RAM and purchased Crucial 4GB kit. Sony recommends Crucial as only authorized after market RAM. I have previously upgraded memory on desktops and laptops and am fully aware about the ESD. I changed the memory 45 degree angle, snap it down....I try turning the computer back on and it will not turn on. Power light is on, the battery light is on but the other 3 lights will not light up and screen does not turn on. I put the original back on and it still will not turn on. I took it to sony store and the guy tries same thing I do and it does not work. He says the motherboard is probably toasted...I said how could it be I followed every direction possible and he said sometimes that the Memory has ESD on it. So they put the original factory RAM back in and shipped it out to San Diego. I thought that warranty was void if you mess with original RAM? Im hoping they'll fix whatever that is wrong with it and not come back with "you messed with RAM warranty is void".....
family member install some additional memory in her Sony VAIO laptop, but seem to be having a problem. Its a VGN-C290 model (May 2007) and currently has one 1GB chip installed & has one open slot. It allows a max of 2GB.
Now, I have purchased an additional 1GB chip from Crucial.com, but after installing it in the one open slot, it appears that it is not recognizing it at all. The laptop will turn on, but doesn't get to the XP screen. Not even the Sony VAIO/Phoenix welcome screen either.
I have never had a problem with Crucial memory, but I contacted them directly to maybe help with this problem. They basically told me to make sure it is really seated in there good and apply a lot of pressure. They also had me put the Crucial memory in the slot #1 where the original Sony memory was. Neither worked.
The only other thing they suggested was that it was a BIOS related issue & to somehow update the BIOS. I checked & it currently is running BIOS version #R0080J4. I'm trying to determine if this is the latest version. If not, then how to update it.
My laptop is an Acer Aspire 6935G with Intel C2D P8400 2.26GHz (1066MHz FSB) and 4GB DDR3 RAM. OS is Vista Home Premium 32-bit.
Under the memory tab in CPU-Z, the DRAM Frequency shows as 399MHz. However, the maximum bandwith for the memory under the SPD tab shows as 533MHz. If I'm correct this means my RAM is running at 800MHz instead of 1066MHz.
I've read other threads mentioning this problem and a solution was a BIOS update to v1.10. My current BIOS is v1.05, which has been on my laptop since new.
I've never updated a BIOS before and therefore reluctant in case anything goes wrong. The laptop is running fine with Vista.
Whats the difference besides $100 less on the E5400 with more bells.
