A novice's RAM confusion

by rivenin / August 4, 2007 4:30 AM PDT

Is there a huge performance difference (speed-wise) between a 2x1GB DDR2 667MHz SDRAM and a 2x1GB DDR2 800MHz? How will Windows Vista Ultimate run on either of these? I ask this question because the difference in the price is too high.

Some, not all the time.

It's a nice up but you should research tomshardware.com to see if he has some machines with that difference. For laptops I head to reviews and benchmarks.

Same for desktops.

However since no make or models were shared I can only note that there could be CPU differences as well since that sets that rate in most if not all machines.

Thanks for the quick reply. I am sorry that I didn't provide you with proper details. I plan on buying a low-end, locally assembled desktop. The processor I am currently interested in is an Intel Core 2 Duo 2.13GHz (E6420), 1066FSB. Also, it will have an ATI PCIe x16 Radeon X1300 Pro, 256MB graphics card to go with it.

So, my questions are as follows -

1. Will an 800MHz 2x1GB RAM make a huge difference as opposed to a 667MHz 2x1GB one?
2. How big is the difference between a 2.13GHz Core 2 Duo, 1066FSB (E6420) and a 1.86GHz Core 2 Duo, 1066FSB (E6320) speed-wise?

It's all about the money. Thanks.

Given the right benchmark program.

In reply to: Details

It's just a simple 800 divided by 677 result. I can't tell if you call that "big".

Other areas will not be affected such as hard disk transfer rate, triangle fill rates, etc.

Nice CPUs with 4M L2 cache so benchmarks should be easy to find on those and should be as easy as 2.13 divided by 1.86 results.

I have the 2.13 but with 2M cache and the real bonus on my new versus my old system is the (non gaming) power draw is now 100 Watts and the old machine run at 200 Watts.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
