    I wish you would have put in some "generic" or inexpensive PC3200 RAM as a base to compare the performance of these chips to.. Reply

    The smaller multiplier allows you to finetune better Trog that's all. Remember the mutiplier is locked. Even though the 2.4 gets all the limelight, some 2.6s get over 300MHz as well (and I did see a post on the net once where 2.4 would only get 230- a bit like an AMD ahmmm scratch that!). Its just the luck of the draw. Mine is a phillipines one and I think the Costa Ricans average better. I overclocked the 2.6 using 5:4 mem on my abit IC7-G which is good to over 300 MHz FSB using async. But at 1:1 it appears that the ASUS P4C800s are the better boards as the high end mem. manifacturers only seem to guarantee their modules on that particular board. My 2.6 gets to 246MHz (3.2Gig) on default voltage, 250 takes an extra .1V and 260 an extra .125V past that again. I use an Aero4 copper heatsink with the turbine removed and an external tube to a fitered Sunon 50cfm on the case (without a fan directly on the heatsink to avoid the dead spot). Temperature is 35-45C (core sensor idle- load) with ambient of ~22C (far worse in summer). Naturally liquid N2 like the cold finger on one of the mass spectrometer sources I worked on would be better but lets be serious!

    I'd be happy with the 246 as I dont like overvolting (especially with the current leakage sudden death rumors) but I want the 1:1 low latency RAM to match that and that would be my final memory upgrade for the system (probably 2Gig). I thought a year after buiding my system it would be plentiful given the fast development curve from 266 to DDR400 with low latency. But I am still waiting.

    Wesley, please correct me or the text below:

    -quote-<i>
    The 6400 <b>unbuffered</b> Sandra 2004 memory bandwidth that we achieved at DDR580 is the highest result we have seen so far on our Intel test bed, as is the 3750 unbuffered memory bandwidth.

    6400 is buffered isn't it?

    Regards,

    That's what you get for going with the higher 13X multiplier of the 2.6C instead of a 2.4C, Pumpkin. ;) Of course, a better cooling setup might potentially help (not sure what you have). Anyway, considering 260 = 520 = ~PC4200, there's really not a whole lot more room to overclock anyway. As the article points out, only Asus and DFI boards are able to reach these high clockspeeds. Given the variation in quality among RAM and motherboard parts, a "lesser" Asus or DFI might not clock quite as high. CAS 2 at 250 MHz would be nice, though. Wonder when (if?) we'll actually see it? Maybe when we start getting 90 nm memory parts? Reply

    Even though its nice to see your 2.4c approach the 300MHz FSB at 1:1, not all of us are so lucky. My 2.6c maxes out at 260MHz so I'm still looking for that DDR500 CAS2 holy grail. Along, I suspect with many others, I'll buy when I see good evidence of this in a memory module.

    CompuSmart Brandon has dealt with Shikatronics for over 5 years and have always received top quality products and excellent customer service. We have purchased from several other memory suppliers over the 10+ years in business and Shikatronics has had the least DOA and quickest replacement time of any of them.

    Way to go Shika keep Kicking Ass!

    We seem to get this question in every new review with graphs that have a lot of bars. We can't provide a different color for the tested item right now no matter how much we agree with all of you. It is a limitation of our current graphing engine, which is used for all reviews.

    There is good news, however, in that a new Graphics Engine is now testing that WILL provide a highlight color for the tested item. It is expected to go live next month. Your patience will be rewarded :-).

    nonono whatever you do don't reduce the number of graphs -- it's much better seeing all memory on one chart than poking around the archives. I agree on the highlight thing though. Reply

    It sounds great, but with the GIANT lots of memory which are included in every test, it becomes hard to find the graph which belongs to the actually tested RAM. Either you reduce the number of graphs to only four or five for each diagram, or you emphasize the tested memory's graph by making it light blue, red, green or whatever colour. It's even becoming hard in an Athlon 64 Mobo roundup. Please do something about that.
