My Sager 8790 Review

post #1 of 5
Thread Starter 
First time poster here, so please be gentle!

I ordered my Sager 8790-S from PCTorque last week. It came in a couple days ago, but I had to wait to set it up. I ordered a second 40 gig hard drive and had to get a USB floppy so I could set up the RAID myself. The extra 40 gig hard drive came in today, so I started work on it this morning.

Upon taking this thing out of the box, the first thing I noticed was the weight. I had a Compaq Evo N800 which is a compact laptop and weighs half of what this thing does. I expected this because it is a desktop replacement and I wanted power in my next laptop. This definetly has the specs!

The first thing I did was install the second hard drive, flip the dip switches on the controller, and set up the RAID array. After disabling the card reader in the bios (I followed the 8790 setup instructions on these forums), I installed Windows XP without a problem. The screen is simply awesome to look at. My Evo had a 15 inch screen and I thought that was impressive at the time. This just blows it out of the water!

Windows XP, the latest drivers, bios, and all my productivity software are now installed on this thing. Now I need to install the games and test out how those run. I don't have any here at work, so that will have to wait until I get home.

Installing everything with RAID 0 was as fast as lightning!

I couldn't believe the performance on this thing. I was done in less than an hour when I started the software installations even with all the reboots!

Other things on the list of things to do to this laptop is to apply Artic Silver to the heatsink on the processor. Going to hopefully get to that by the end of the week. I am going to test this laptop out and show it off this weekend. I hope things work well with it!

Benchmarks and a full gaming report are coming in the next week!

Nice mini-review.

Just a quick question. To setup RAID do you absolutely have to use a stiffy disk to setup the RAID drivers? Before installing WinXP?

Or can you just burn it to a CD or something like that?

I had a USB floppy handy so I used that. To my knowledge, after reading the FAQs, you need to have one to install it. When Windows XP setup comes up, it reads the floppy disk, not the CDrom drive for the SCSI driver. I don't think a CD drive will work.

I installed Artic Silver last night. 6 screws to remove the plastic cover and fan to the heatsink and processor. Next, I removed the 4 spring loaded screws to the processor. Gently I pulled up on the heatsink and processor sink and got them apart. I was most nervous during that process. Using the Artic Silver guide to the 5690, I applied that grease to the processor and I went from 45 degrees idle temp to 37-38. Nice.

I am going to start doing benchmark testing this weekend.

The refresh rate of 8790 screen is 60hz at native resolution 1680x1050. 60hz usually gives me a headache. Do you notice any flicker at 60hz? Are you experiencing any headaches? (I'm asking everyone that did a 8790 review this same question)

thanks

hi miller,
To simply answer your question, no you don't get a headache from watching a 60Hz LCD than from a 60Hz CRT. This is because the two screen technologies operate totally differently.

With a CRT screen, an electron gun produces a stream of electrons that is swept swiftly across the (L->R) screen, exciting the phosphor coating on the mask of the screen. It will produce a full picture once the scan has reached the bottom of the screen. And then it repeats this process by going back to the top of the screen and starting all over again. If it does this quickly enough (i.e. over 75 times a second) the eye will not be able to see the flickering. So when a CRT is running at 60Hz you will definitely notice it.

However LCD works differently. Each individual pixel is controlled by the application of a voltage to that element. The amount of voltage will determine the brightness of the pixel. But as you can see no scanning is required in order to create a full picture. i.e. if you want a block of white pixels, you apply maximum voltage to just that matrix of pixels and as long as the voltage is there, they will stay white.

Technically speaking, when compared to the refresh rate of a CRT monitor, then it can said that the LCD panel has a refresh rate of inifinity, since it can be seen to be constantly displaying a full screen at any instance in time.
