Is my subject title a reliable setting as oppose to using the Manual setup? My Bios has the setting Bank Interleave as Disable. Yet, if I set the timings by SPD, as oppose to Manual, the Bank Interleave settings goes to 4-way. At this time, I do not know if my RAM is capable of the 4-way Bank Interleave. F.Y.I.: memory are Micron PC2100 DDR 256MB single sided chips. I would appreciate any comments. Thanks.

Use SPD. SPD stand for Serial Presence Detect. It is a chip on the memory module that the BIOS reads to get the exact specifications of the memory. If the memory wasn't capable of 4 way interleave the the SPD chip wouldn't say so. Not all RAM modules have SPD, hence the manual setting for those that don't. Stuart

Thanks StuartS. Reason I was asking was because I read on some websites that the SPD was not a reliable setting and give you slowing settings than the memory is capable. I'm still working on DRAM Command Rate, Trp, Tras and Trcd. Thanks.

You've got PC2100 memory & 266FSB CPU & you are concerned about timings..........;-) You need to upgrade if you are really looking for noticeable performance boost. How To Ask Questions The Smart Way

No Sabertooth, I am not concern at all. I am waiting for new memory that I ordered to boost my memory to 2 GB, but in the meantime I was experimenting with what I have to see if I could get an increase in performance. You see, when I updated my Bios, the Bios setup for DRAM clock/driver settings changed from what my User's manual shows. I've been all over the Internet getting info on these additional settings and how it would affect my memory if I change them. My mobo is a Soyo and they have not responded to my emails, so I am hunting around for information to experiment with these changes. All my data is backed up and I am planning on doing a complete clean install of my Windows XP Pro when I get my new memory. Thanks for your response.

gilloz, There is one important fact that I suspect you're overlooking. It's senseless to run the RAM at a faster bus speed than the CPU. A CPU:DRAM ratio of 1:1 will give the best peformance. So no matter what RAM you get for your AXP 2100+ setup, it should be clocked at 133MHz (DDR266) unless you're overclocking the CPU. It doesn't matter if you get PC2700, PC3200, PC3500, PC3700, etc, it should still be clocked down to PC2100 speed (133MHz) to match the CPU FSB. In a situation such as that, you should NOT be using SPD...you should be configuring the RAM manually. And whenever possible, you should run the 1T command rate. Here's a "for instance": Let's say you get PC3200 RAM that has SPD timings of 3-4-4-8 when run at 200MHz (DDR400), but you intend to run it with your non-overclocked AXP2100+ (13 x 133MHz). If you underclock the PC3200 RAM to 133MHz (DDR266), you should be able to tighten up on the timings significantly...probably 2-2-2-6. BIOS Guide - RAM Settings

Ok Jam, that is a good link. That's what I meant about looking around for this information and this is a good one. BTW jam, I took it off of SPD and is now in manual. I left the Bank Interleave at 4 way and my settings are presently 2.5-3-3-6-2T. Change it to 1T huh? Ok, will give that a try. Thanks.
