Ok so the title explains itself.
I dont know what my rig needs right now.
So first Im thinkning about ram. Right now I have 2 sticks of 512 and I was thinking about just getting two more sticks of that. Should I do that or get a 2gb kit = 1gb sticks x2? It would cost more money that way but the ram I have now isnt that good. But it works for now.
What do you think about these rams?

well sorry for all those links some are over the price range and there are still more i was looking at. *** is the differnece between all those corsair xms? theres like 50 different xms! is a lower cas latency better? is like 3-3-3-8 better than 2-3-3-8?

You've got an sli mobo, how about another gfx card?


I reckon its probably best to get 2x 1Gb, especially if you can upgrade to 4Gb later on.

but I would save like $120 just getting 2 more sticks of 512mb. I could take that and put it towards the video card. Anyone else know the questions to my previous post above?

The lower the latency the better ie. 2-3-3-8 is better than 3-3-3-8.
I'd save the money and put it towards a new GFX. With the 6600GT you're not going to be able to play games at the settings that need 2GB of ram so it wouldn't be of much use really.

Ok but say this was just about the ram. How much difference between the latencies? Of the links above there were Identicle corsair xms with the same specs but they cost different. Is DDR500 a lot faster than DDR400?

I agree. Get another 6600GT, as two more sticks of 512 will slow you down a little bit. Four sticks puts a lot of strain on your mem controller.

It depends on the application that you're running. For games, very little difference in performance between say 2-2-2-5 and 2.5-3-3-8. Games are mainly dependent on the GFX, but it will make a small difference. Similarly with speed; you might gain the odd few FPS with DDR500 over DDR400. Nothing to write home about really. The big increases to gaming performance would come with a GFX upgrade. IMO, ram should be the last consideration of a gaming system. As you have 1GB, that should be fine for now.

Well how much difference would there be between a CAS latency of 2 and a CAS latency of 3? What about the difference between 3-2-2-8 and 2-2-2-8?EDIT: Still what is the difference between all those xms?

A big difference.

As a general rule, don't buy memory with a CAS latency higher than 2.5. Lower latency = faster memory.

There would be a big difference between 2-2-2-8 and 3-2-2-8 but I have never seen 3-2-2-8 timings if you mean 2-3-2-8 not much of a difference.

If you are gonna get the ram go with either these
OCZ Gold
G Skill

But like stated before save the $250 and when you get more get a new video card.

now what about overall in general?

If you want specifics answers, you're going to have to ask specific questions.
What apps are you running, which timings are different, if it's for games what resolution will you be playing, what detail settings are you playing at etc?
If you can give us some info to work on we can help much better.

In reading your first post seeking 2 x 1024Mb RAM modules for under USD$ 250. I would have to say the G.SKILL F1-3200BIU2-2GBHX..here..at USD$245 would be quite hard to beat.

You can also drop down to the G.SKILL F1-3200PHU2-2GBZX..here..at USD$194

As for the rest of the post I too would be looking to upgrade the GPU before the RAM as more performance for your requirements would be meet.
ie: check out the 7800GT..here..for USD$269.

cheers

Well first of all I forgot to finish my post with links.
Ok I will use the ram for gaming mostly. The res will be proly anywhere from 1024x768-1280x1024 anywhere in that range.
1. For anything in general if you had 2 1gbx2 sets and they were identicle except for one had a CAS latency of 2 and the other a CAS latency of 3, how much difference would you see?
2. For anything in general if you had 2 1gbx2 sets and they were identicle except for that one had a mem timing of 2-3-3-6 and the other had a mem timing of 3-3-3-8, how big of difference would you see.
3. Is there a big performance difference between these

4. What about these

5. Is this one good? It looks sweet.

At those resolutions, in new games the ram timings and ram speed over pc3200 will make little difference. You're talking a couple of FPS here and there, if at all.
The bottleneck is on the GFX and not on the CPU or the ram.

If you're thinking of upgrading the GFX to a 6800GT or an X850XT or above, 2GB of ram would be an advantage as it will reduce choppiness at high texture levels.
If it's going to be paired with a 6600GT then I don't think it's worth the investment as you won't really see any increase in performance.

Well thanks. It will eventually be paired with a 7800GT. Can you please help me out with the pther questions in my previous post? One more Q, is the corsair xms series good?

I'd stay clear of the Corsair. The first set are overpriced and the second set won't perform as well as the G Skills.
I went for the ZX set over the HZ, but either set will perform very well at an excellent price.
