can't quite get the memory timings

[hermeticist]

I`m sure that the Seasonic will be fine, just like to give you a choice.

I was under the impression that nothing has colour as such, only the spectrum of light reflected from its surface gives us the illusion that the pink elephant sat next to me is pink....Damn it`s gone. Although that may be due to the fact my PC cooler has at last descended to zero kelvin!

i have the XFX nForce 680i, i like to get my motherboard and graphics card from the same manufacturer so that's why i went for this.
i don't usually overclock anything but i have tried overclocking my CPU and i have slightly overclocked my graphics card just because it only raised the GPu temp by 2'C.

i don't really know how to overclock RAM..
only the timings of it.

If modular is not an absolute then look at the Corsair VX series, 550 watt. 41 amps on a single rail.
I am in the process of building for a m8 a quad 6600 2 GB ram 2 HDD and a 8800 GT.
Currently soak testing with prime 95 it hasnt missed a beat.

Reading that yes you are

when you say modular do you mean the ability to be able to remove cables from the PSU when you don't need them?

i might take that into consideration, need to see how much i get for my birthday first, 16 years old , march 9th.

i also want to get another 8800GT and SLi them so i also need the new PSU for that i'd reckon..

if you have time could you please explain this amperage thing on the rails to me?
i do systems & control at school and we do this kind of stuff but i don't understand how a higher amperage is better..

First to understand why more "Amps = good" you need to understand a few things firstly power is measured in Watts (guessing you know that ) and Watts are a product of volts and amps so

volts * amps = Watts

Now if you have a 12 volt supply which can provide 120 Watts then the supply is rated to 10 amps if it can provide 240 Watts then its rated at 20 amps.

Hopefully you can see that more amps means more available power, at a given voltage.

Rails are actual or theoretical splits within the PSU which mean that you have 2 or more 12v supplies so if you have a single rail it may be able to produce 30A (360W) or you may have 2 rails which have 18A each so a total of 36A (432W) these rails however are limited to 216W on each rail so if you exceed the total power for a single rail that would be bad, the rails could be distributed to provide 1 for the PCIe connections and the other for everything else, for example.

As you guessed modular means that you can remove cables that you do not require or rather only plug in the ones that you do! This means that you will have fewer cables in the case so it should be tidier, and a tidier case is a happier case!

Hope this helps.

right.. i understand that much better now 12v rail with 40A = 480w?
the higher the amperage on the rails the better?

thanks for the help

personally I would stay clear of SLi. Why you ask?
Well the gains versus expense. On average you may gain a 1.5 increase in speed ie Frames per Second this is game dependent if it wrtten into y=the driver to support that game.
To obtain a visually smooth frame rate 60fps is the general rule, depending on what monitor you are playing on and therefore the resolution a single card such as the one you have is more than capable of giving sooth performance up to a 22 inch LCD.

By the time you come to get that second card a newer generation of card will be out that will provide even better performance.
Evidence of that is the current 8800 GTS 512 G92, this will come within a few frames of the G80 8800 GTX that I paid £400 for early last year
A GTS can be got for £200, see my train of thought?

Get a trial copy of FRAPS run your GT on your favorite game and see what framerate you are getting, hopefully that will provide evidence that you dont need SLi.

[matty-hodgson]

yes, 62FPS i'm getting on average on CoD4 on all very high with AA off.. i see what you mean, good eye candy then, just about it.. and by that i mean inside the PC..
i'll keep my money and buy a good case and silent fans and a good PSU then
and maybe an extra 2GB of RAM.

Overclocking the CPU means increasing the FSB. That also clocks the RAM higher, but I would expect the RAM to be well within its rating unless you did some serious overclocking.

XFX are not a top tier manufacturer. Reviews suggest memory performance is not very good, but nothing suggests that anyone had problems with timings. I'd guess that either the mobo or the RAM are not quite in spec. Try one piece of RAM at a time and see whether either will run at the spec. If neither I'd blame the mobo, but it will be hard getting an RMA.
