I agree with the statement about timings not really helping real world apps very much though, eg. games, but for media encoding quick ram will speed up this process considerably.

Interesting.

So tighter timings will not help with the quick "lefts and rights or Ups and downs" with the mouse in 3d games?

The only thing that will help that is ram bandwidth(I.E. faster ram)?

In other words, there doesn't seem to be this other realm of how quick a First Person Shooter is?

ONLY frames per second matter in games, not the actual timing of your RAM?

Is there any 300mhz RAM for AMD's??

In that example you give, it pretty obvious what the choice is.
But let's be real here:


It's more like 200mhz ram OC'd to 220mhz at a 2-3-2-5 timing
vs
250mhz ram running at 260mhz at 3-4-4-8

So in a real world comparison the questiion would be this, " is 30-50mhz worth the drop in timings"?

Basically your post is a useless one. (IMO) You have been given the skinny on what we think.

Now do YOUR research and make up YOUR mind which is what really matters to YOU.

:Edit:

Yes there is 300MHz DRAM.

This thread has the awnser to all your questions. Read it. It is a thread showing how much a timing equals in MHZ. It shows that 2-2-2-5 @250mhz = 2.5-3-3-6@255mhz.

Wow, ok then so timings in the end CAN BE equated to MHZ.

Geez the whole time I thought low timings would give you a level of snappy smoothness in games no amount of ram MHZ could give you.

I guess I'm wrong??

In the end they BOTH jsut end up with the same result, just a different way to reach the same goal?

If this is true I just got the answer to the question I've been wondering the last week.

Fairly correct. Timings indicate how many clock cycles (Hz) the ram takes to perform a function:how long it takes to access a row, how long it takes to precahrge a column etc. For example CAS (first number in the x-x-x-x style timings) stands for Column Address Strobe. When you set CAS to 2 the ram has 2 clock cycles to access the column it wants.

For more reading Here is the oc.net ram timing guide.

I'd just like to thank you guys for pointing all this info out.

I just tested my gskill ZX ram and it's hardly better then my 4x512 setup.
I can get it to run at 217mhz at 2.5-3-2-5.
ANYTHING past 200mhz with stock timings(2-3-2-5) and it crashes.
This ram is weak.

After reading what you guys have provided, its clear to me that in my situation I would be MUCH better off going with the HZ stuff running it 1:1 @ 260mhz 3-4-4-8 then this ZX ram @ 217mhz 2.5-3-2-5.

THX guys and also the fellow Oregonian.

That Ram will perform much better at cas 3, as do most 1GB sticks. Try setting it to 3-4-4-8 and see how far you can push it. Should get some good results and speed.

It won't go past 235 at 3-4-4-8

This ram used to be good a few months ago, but if you read the huge thread about this ram over at extremesystems.com, you'll see that my performance is right on par with everyone else.

They switched to different RAM chips abit ago and this ZX really isn't that good anymore. At least, my ram isn't getting the type of clock speeds and timings that people were when this ram first came out.

It's no wonder why the ZX stuff is under the "value" section where as the 500DDR stuff is considered the "extreme" stuff.
