Which RAM to choose! - Page 3

post #21 of 30
Thread Starter 
I hate to be an idiot and double post to get attention, but I would like to know whether good quality RAM, with fast timings affect much in a game, compared to some value RAM at 3.3.3.8, both the same size? Like I said in the last post.

Thanks in advance.

He has a socket 754 motherboard, so dual-channel won't matter. As to your question, there is certainly a performance boost between RAM with tight timings and RAM with looser timings. This is why low latency RAM costs more , although I don't know exactly how much of a performance boost it actaully gives. If I were you, I would just get a good pair of 512MB sticks, maybe some BH-5 or TCCD, and OC it. Games like Quake 4 and BF2 can't run at their full potential when you have a 6600GT anyway, so I would just stick with 1GB.

Noooo.... it is a 939 board
I know it costs more because it's faster, but does anyone at all know of any benchmarks (Game benches in particular) anywhere to do with this? If you can't be arsed to type, please just give me the link or whatever. It looks like no one knows

I did read in a another thread that timings do not affect real time performance that much, it is only noticable in benchmarks. So now I ask myself this: Is there any point in buying some expensive RAM, that can be overclocked, or some cheap stuff, that can't? It kind of misses the point of overclocking; getting the most out of your hardware...

Relly...I thought the DFI Lanparty nf3 was socket 754...

As to getting cheap stuff that can OC well, get the G.Skill in my profile. Only costs $140 and has Winbond UTT-BH5 chips.

well with tighter timings you'll probably see about a 2-5% increase in performance. I haven't done the benchmarks myself but I would assume the difference would be similar to the difference between a 1T and 2T command rate. there is a 20-30% difference in synthetic tests, but in real life and in FSP you only see a 2-5% difference.

I would spend a little bit more and get quality RAM. There is a slight difference in timings... but the big difference is frequency. if you can OC and run DDR500 even though it will have looser timings than DDR400 you will have better performance with the faster speed. Overall frequency is the most important. so get some quality RAM that will be able to run tight timings at DDR400 and will be able to OC.

BH-5 will run up to about DDR520 or so but will keep tight timings
TCCD will run up to about DDR600+ but you will have to loosen the timings a bit. most TCCD will do DDR500 @ 2.5-3-3-7 and DDR600 @ 2.5-4-4-8. Also, TCCD requires a lot less voltage so it does not need to be activly cooled.

Thank you! I've been looking for this answer everywhere
So the thing is: Only get good quality RAM if you can afford it/going to overclock it.

Am I right?

well regardless of if you plan to OC it is always good to get high quality RAM. even at stock speeds you'll get better performance w/ tight timings. That's why OCZ makes a gold line of RAM. the Gold series does not OC as well as the Platinum series but has tight timings at the specified timings. the bottom line is that tight timings will give more performance than loose timings.

Thanks, I do understand that, but I was also wondering if anyone has investigated this before, and recorded what sort of performance increases there are? Sorry if i'm being a pain here, but I would like to know.

You'll be hard-pressed trying to find actual numbers that show that tight timings are better than loose timings. It's pretty much a given in the harware industry. The real question is whether tight timings with a decent HTT are better than a higher HTT with looser timings (aka BH-5 vs. TCCD). The guys over at XS have sort of figured out (no hard numbers...yet) that DDR540 2-2-2-5 is about even with DDR600 2.5-4-3-8. Shift the HTT lower on both the BH-5 and the TCCD, and the BH-5 will be faster. Shift the numbers higher, and TCCD will be faster (mainly because DDR540 is basically the absolute limit for BH-5). So it really depends on how well your CPU overclocks and what HTT would satisfy that, so that you can buy RAM accordingly.

Ok cheers, finally what I was looking for! It's all quite complicated and annoying really, but nothing is simple.
Thanks for everyones help, useful or not, I now have something else to think about.

Oh and I never replied to your other post, there is another nForce 3 ultra board that is made in 939:
