5793 ram upgrade worth it?

Just got my 5793 in 2 weeks ago. I love this thing! I got it shipped with 4 gigs of ram but just knowing I can upgrade to 8 gigs if I wanted to is getting quite tempting. My question is this, is it worth $320 to upgrade to 8 gigs? Newegg has the 4 gig sticks for $160 each. Would I notice a difference? Or would it mostly just be the "e-peen" factor?

I'm thinking it would be smart to wait a couple months or so to upgrade, hoping that the price goes down some. If it really isn't worth it the upgrade performance wise, then I may wait longer.

 

It'll be smart to upgrade only if you use up the whole 4GB frequently.

IMO 4GB is enough for intensive tasks.

Keep monitoring the memory usage in tskmgr, and if it doesn't go above 80%, there is no point in upgrading the memory.

 

I agree with Andy, unless u plan on doing some really intensive work, 4GB is more than enough for now

 

The PM965 chipset in the 5793 only supports up to 4GB of ram at 667Mhz.

 

No it does not, it supports up to 8GB addressable space, so you'll see around 7GB if you have 8GB installed (depending on other hardware)

 

Ya I noticed everest said that I have DIMM-1 and DIMM-3 fitted with 2 GB sticks each. I guess this means I have a DIMM-2 and DIMM-4 and thus the possibility for 8 GBs total? I have the older 5793 RU though not the TU.

 

Nope, just 2 slots, but you can put 4GB sticks in each

 

Ohhhh. That sucks. Waste of 2x2GB sticks .

I know, I know, sell them on ebay.

 

The reason that everest reports dimm-1/3 is that the chipset has support for 4 sticks of ram. For dual channel, you need to use slots 1&3 or 2&4, hence why the 2 physical slots are connected to those points on the chipset.

 

I asked SagerTechsupport about 8GB (I'd like to upgrade RAM in my Sager NP5793 from 4GB to 8GB. Is it possible ....?).Answer:

This Model only support up to 4GB running Vista, The Bios has not thing to do with this.

I call bulls**t on this. Vista 64 supports up to 128GB RAM (for business/ultimate) and 16GB for home premium.

The chipset on the 5793 supports 8GB addressable space, so you will not see quite the full 8GB, but you should see 6.5-7.5GB.

If the chipset only supported 4GB addressable space, then you would not see 4GB if you had 4GB installed, and I can personally tell you that you do.

 

Could someone test 8gb in np5793 ?
I don't have 2x4gb ram available to play with.

 

neither do most people...

 

Maybe you want to take it up with Intel since they disagree with you.

We're talking about the limitations of the chipset and not the OS. The 5793 will not accept more than 4GB of ram even if you are running Vista 64. If it could then I would have put 8GB in the notebook a long time ago.

 

You should have upgraded to 8GB a long time ago. That datasheet hasn't been updated since the day it was released, and in June 2007 Intel didn't know what were 4GB SODIMMs. Maybe you could take it up with Intel, as to why they've been so lazy.

 

I have read success test on some notebooks with santa chipset so...?:

G.Skill has nice price for 4GB: linkA
or 8GBkit (2x4GB): linkB

For Windows Vista to use all 4 GB of memory on a computer that has 4 GB of memory installed, the computer must meet the following requirements:
• The chipset must support at least 8 GB of address space. Chipsets that have this capability include the following:
• Intel 975X
• Intel P965
• Intel 955X on Socket 775
• Chipsets that support AMD processors that use socket F, socket 940, socket 939, or socket AM2. These chipsets include any AMD socket and CPU combination in which the memory controller resides in the CPU.

• The CPU must support the x64 instruction set. The AMD64 CPU and the Intel EM64T CPU support this instruction set.
• The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect (PCI) configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer. View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature.
• An x64 (64-bit) version of Windows Vista must be used.
Contact the computer vendor to determine whether your computer meets these requirements.

Note When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating system is always less than the physical RAM that is installed. For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install 8 GB of RAM, the system memory that is available to the operating system will be reduced by the PCI configuration requirements. In this scenario, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately 200 MB and approximately 1 GB. The reduction depends on the configuration.


I think SAGER is in the same possition as other integrator. They need to sell new models and earn as much money as it's possible. Nice example is here (on 13min05sec): The Story of Stuff

 

Here is a nice link where you can combine various HW parts to M57RU (shoud be the same as Sager 5793). Example: Nvidia 9800GT; CPU X9000; 8GB 2x4GB DDR2-800 CL6 200pin; 512GB SSD (crazy price or I have som problem with my eye)...etc.

 

lol...old thread.....

 

woohoo my old thread is back from the dead! Thanks for the link though...

 

8GB RAM works on Sager NP5793 for sure!
I successfully tested two of them:
Kingston SODIMM 2x4GB DDR2 667 MHz CL5 (KVR667D2S5K2/8G)
Kingston SODIMM 2x4GB DDR2 800 MHz CL6 (KVR800D2S6K2/8G)
Now I'm using 800MHz.

 

What brand is that RAM you found on newegg??

I know what we buy our Crucial 4gb sticks for and that price sounds really low. Really Really low...Red flag low if you know what I mean.

Just curious.

Thanks

 

I spent 260Euro. So don't know if it's too much or standard price here in czech republic.

 

Very nice, jrompf. +1 rep for you.
