I just bought SZ38GP, English XP Pro but I think it is Asian model, similar to European 5 series, the CPU is T7200, and GPU the 7xxx. SZ are perfect for my DJ work, and secondary notebook, I was using the SZ1 till now and wanted to get the best there is from this series, possibly fastest CPU but no 8xxx Nvidia. It came with single 1G RAM, I could put another 1G from my old SZ but would rather have 3G total= add single 2G chip. I remember that SZ1 had 2G RAM limit but cannot find out about the SZ38GP C. Will I be able to use 3G with it ?

Still owning an old Sony SZ1XP laptop and was wondering if anyone have ever replaced the stock HD with a newer 7200 RPM HD
Main question i would like to ask if i am limited to a certain size of 7200 RPM HD
For example: in this site [url]
It says the following "up to a 120GB 5400RPM hard drive"
Does this mean i can only fit a harddrive of max. 120gb in the laptop?
otherwise that it is possible to put a bigger sized hd

so story is, i jump on a new game called Demigod, cpu running at 2.8ghz , after about 5-10mins of playing, i notice both my cores are running at 100% and the game lags like crazy, frame rate goes down really bad.
so i figure, hm, cpu bottleneck for a game.. strange.. lets have some overclock fun - i go ahead and set my x9000 to 3.4ghz, now the game runs great, my cpu cores dont reach 100% and the frame rate is great, all is good and great. only problem with running at 3.4ghz is that after about 30mins-1hr of playing, my m1730 powers down due to what i can assume to be overheating

I got my system over weekend with following config
P8600
2GB DDR2
160GB
FullHD
Vista 64bit premium
I'm planning to upgrade RAM and I'm thinking if it is worth upgrading to DDR3 instead of DDR2 4GB. Price difference between two seems to be like $20-$30.

I just bought a new Vaio. I want to upgrade the hard drive to a 500GB but there is no Vista DVD in the box.
Is there a way to create a DVD and then install Vista on the new hard disk?

One of my users has a Vaio SR and is trying to create recovery discs (DVDs) using Sony's tool. Sony's application fails at 24% every time with the following error:
"The disc could not be created.: Missing source folder or files."
It's running Vista and is pretty new, although they repartitioned the drive recently have installed a lot of additional software and may have uninstalled some Sony software. I'm thinking these could be the cause.
If not, any recommendations for third party software that provide similar functionality (full system backup images to disc)?

I just installed my 4 gb of RAM in my Inspiron 9400, fully aware and knowing in advance that I won't be able to use more than 3.25 of it with my Vista Ultimate 64-bit OS...
My question is: WHY? Is it because the Bios can't address the memory in 64-bit? Just for curiosity, is there a way to make the OS bypass the BIOS (If it's the cause) and fully use the 4 GB?

I have a e1705 Geforce go 7900gs oc'd to 450/600. Also I have the power supply that is included with the laptop 90watts. I have seen people here in forums that o'cd there card up to 600 core or more. I flashed my rom using the 375/507 to unlock my bios and then i use rivatuner to overclock my video card coz I want to know the limit of my card. And it reached 455/600 so i underclock it to 450 just for safe distance.
Now, I am using ntune to o'c my card and there is no testing whether it will work with the core I specified so I assume again that its 450/600.
My questions will be,
1. What is the max core/mem overclock that is safe for my 90 watts power supply w/o increasing the voltage to 1.24volts?
2. I create a profile in ntune that I enable the overclock (450/600) everytime I will play 3d games and I get it back (370/507) . Is that ok? Will it harm my videocard?
I got a rev 1 card. I am using a windows vista w/ dell performance driver, 2gb ram and 1.73ghz core duo cpu. Weird I got 152 increase in score in 2005 3dmark when using vista to xp . My score is 7196. And also I don't want to use nibitor to o'cd my card .

The instruction booklet says there is a 2GB limit, and that I can only use two 1GBs. That sucks because it comes with two 512MBs. Is this true, or could I go buy a 2GB DDR2 and replace one of the 512MBs? It's a Acer Aspire 5315-2153.

I have an Acer Ferrari 3400 and i just replaced my hard drive with a 160 GB drive, however the computer only sees about 131 GB. I've read abit about the 137 GB limit and wanted to know if the motherboard/BIOS for this model supports 48 bit LBA so that i can see the remaining space on the hard drive. I have windows XP pro service pack II installed, but i don't know how to activate 48 bit addressing or if my BIOS suppoerts it.

I've recently posted a question here Total Memory in task manager incorrect after upgrade to 4gb Aspire 5735 where I received some great help. However I've done a bit more research and I'm starting to fear my notebook may be limited to 3gb by the bios/chipset for some reason. I have just upgraded it from 3gb to 4gb. The bios shows 4gb as the installed amount but memtest in dos mode only shows 3000mb total as does windows task manager.
So it appears the notebook detects the 4gb installed ram but only allocated 3gb.
My question is does anyone know if acer has limited this notebook to 3gb total and if there are any suggestions on getting around this limit?

I set up mail with my Gmail account but I don't want it to download all my messages. Is there a way to set a limit to how many messages get stored in the computer? I have way too many messages and don't want to waste hard disk space.

In my Win 7 X220 and Win 8 Yoga11s, both had Lenovo programs (Power Manager and Lenovo Energy Management respectively) that allowed me to maximize battery health by setting a charging threshold. In the TPY, is there any Lenovo programs that does that too?

Does the Dell Studio XPS 16 use ddr2 or ddr3? I am not sure, but I am going to guess ddr2 based on the 3dmark06 scores. Does anyone know for sure?

I just checked newegg and it looks like you can get 2gb (2x1gb) for like $55? This would be for my 9300. When did prices dip this low? How much longer do you think it will last (will they rise back up?)

I found a nice deal over Dell.com for this memory - yes, I know it's crazy but that was the cheapest place I found, they offered 15% off + FREE Next Business Day @ DHL, which sounds pretty good for me.
I'm going from 2x1GB DDR2 533Mhz to a 2x2GB OCZ DDR2 800Mhz@667Mhz with lifetime warranty for as low as $44 each module. I think will be great upgrade since my 2GB always wasn't enough!

I have Acer Travelmate 7520G (Turion TL-58) and upgraded from 2G of 667Mhz RAM to 4G of 800Mhz, however the memory is still running at 667Mhz and FSB:RAM being CPU/6. Chipset here is Ati RS690 and according to Everest it supports 800Mhz DDR2. There is no option in bios to change the RAM frequency or divider.. I have tried updating the bios with no luck.

there seems to be a consensus that hdx16 is ddr2, but some people seem to be saying hdx18 is gddr3? this doesn't seem to make financial sense from hp's side, but it would be a factor in deciding between the two if it were true.

I see that thread BIOS Update V1.24: 4GB RAM in 9410? was already locked (yes, I missed it by more than a year).
I'm guessing there are still users out there using their Acer Aspire 9410 laptops.
I recently purchased two 2GB DDR2 modules. They both work fine individually and I've tested using memtest86+. When I plug both modules in, the BIOS only sees 3067MB. The Phoenix BIOS in my Acer Aspire 9410-4933 is version 1.24. I would expect that the BIOS sees all 4GB.
Is there any Phoenix BIOS newer than 1.24 that I can use for my Acer Aspire 9410-4933?
I've read that there may be hidden BIOS settings and I'm wondering if anybody can point me to a URL that describes how to un-hide those settings?
Lastly: according to the aforementioned locked thread, the BIOS is the one limiting how much memory is addressable. Is there any way to hack around that?
