What is the Difference between value select and the XMS PC3200 DDR 400 line from Corsair? I had one stick of memory go bad so I using only one stick 512k stick of the XMS PC3200 for about a week before I got the RMA for Corsair. Now I have only one stick of Valuse Select Kingston memory, PC3200 DDR400, and my system seems to run the same it did with the Corsair memory. My timings are/were 3,3,3,8 any help would me great.
1) welcome to the forums 2) the differences are in timings and overclockability. If you're using an intel system, the timings play less of a part than the overall FSB, so you'll notice less difference going up to 3-3-3-8 as long as it still runs at the same speeds. The corsair runs at 2-2-2-5, which is the fastest ram gets in that department. If you use AMD, this hurts your performance quite a bit. You're also no longer running in dual channel mode with 2 types of ram like that. This will hurt your performance considerably. Chances are you're just not maxing out your ram as much as some people, so you're not noticing, but if you ran benchmarks before, compare them to now and you'll see a bit of difference. Hope that helps!
Firstly, that corsair does not run at 2-2-2-5, it's the XL (and old BH5 LL) that's rated at 2-2-2-5. Secondly, if you don't overclock, you won't notice any difference between value ram and super expensive ram rated at the same speed - the only difference is timings, and at stock speeds the difference will be unnoticable for general usage (you will notice a slight difference in benchmarks). If overclocking however, the ram with tighter timings is likely to reach higher speeds as there is always the option of slackening these timings to reach higher speeds. There are always exceptions to this, but this is generally how it works.
Jumper, Sorry, make those timings 2-3-3-6. But to say you won't notice a difference going from dual channel to not...of course, he didn't specifically say he was using a matched pair, did he? And timings do make a difference in performance, they're not just so you can relax them to OC higher. Depending on system (amd v. intel), they will have a visible or negligible effect when the system is under significant load.
I was answering this question, my comments have nothing to do with dual channel. I do agree, you probably would notice a difference between dual channel and single channel - more so than just a difference in timings at least
Thanks for the help so far, and yes the the Corasir mem is the TwinX matched par, just that one stick was bad. I had to RMA both stick to Corsair. Still waiting to get them back. I have an AMD Athlon 64 3200+ skt 939 2.0 GHz with an Asus A8N SLi-Deluxe mobo and an XFX 6600GT, another question (I am really new OCing), but what would be the best way to oc the prossesor and ram, maybe even the Video card but that would be for later. Also I am talking about the Corsair XMS PC3200. Again thanks for all the help.
