Kingston vs. Corsair , 3200 vs. 3500

[Kioku]

Is there a noticable benchmark difference between Kingston and Corsair memories of the same bus speed and latency?

Is there actually a difference between running dual channel 433mhz and dual channel 400mhz?
From the looks of it, 800mhz will be the bottleneck since the current mobo and cpu only support up to 800mhz.
Is overclocking the only use for 3500+?

If they have the sane latency and bus speed they will be VERY simular.

The timings are the key, depending on the quality of the modules, and both kingston and corsair sell different levels of quality as far as timings go, in both cases they claim thier low latency modules run at 2-2-2-5, on some of the new i865 and i875 chipset boards this isnt the case, poeple have been having tremendous problems with their LL ram, some however have been able to correct this problem by increasing their voltage to 1.75, i would research the specific motherboard you are planning to buy to make sure that low latency modules will run without problems. otherwise if you plan on just buying the regular modules that run at 2.5-3-3-6 you shouldnt run into problems.
It would be wise to research this issue further, because of recent problems.

As far as the Speed of the DDR i would suggest buying pc3500 because it will give you some room to overclock, and also be more future proof then pc3200.

thanks XeeN,

I want to get p4p800dx, but from the looks of it, nothing works with it, neither corsair or kingston can reach the ideal latency with this board.

As for tweaking the memory manually, it seems it may not work 60% of the time ( i spend quite some time reading all the p4p problems on the corsair board). Ram Guy suggested all sorts of timings from post to post. The conclusion i came at is that to get stable performance with the 3200C2 / 3200LL rams there will be substantial sacrafice in the timing. In the field of 2.5-4-4-8 for 2*512

With today's article release on memory tweaking, a timing of 2.5-4-4-8 would be way below the average of what they had. Even though running at 2*256 would offer less problem, i don't think anyone would be comtempt with 512ram.

I am buying my system in a few days from a local reseller, I might take the route of Kingston HyperX, the road less taken, and try my luck.

I think it's better when I understand nothing about components 2 month ago then i won't have to worry about any of these!

people seem to be having good luck with the i865PE chipset with the corsair, and kingston Low latency modules, i suggest the IS7 from abit if you dont want to take any chances, it got excellent reviews and everyone has been happy with theirs.

I am running 2x512 sticks of corsair xms 3500 c2 in my Abit IC7-G with agressive timings 2,5,2,2 at 434mhz no problem...ROCK SOLID
Corsair is the way to go.

yeah the corsair xms C2 modules have been running fine, they havent had any problems on the i875 that i have heard of course i dont know everything, maybe you just lucked out.

I read that xms3500 is more tuned for 875/865 ?

just use the tightest setting you can and hope that BIOS revisions will allow you to tighten things up over the next few months.
