KT7A-Raid worth the upgrade from KT7-Raid?

[hoonose]

I recently purchased 2-128MB sticks of OCZ 166 222 memory to replace previous PC133 cas3 memory, in hopes of increasing my 1200 TBird KT7-R performance. I have realized absolutely no benefit to the change, still being limited to 112 HCLK+PCIClk. 112x12=1344. Does this mean that I am running the memory at 100 + 12=112 MHz? Or, 133+12? What can I do to boost the memory speed? Any ideas what speed I could run the memory if I went to a KT7A-R board? Does that upgrade make any sense? My current setup is really not all that stable, probably cause I'm fooling with it too much. 30 GB IBM DeskStar Raid-0, SB Live Value, Gainward Geforce3, Kingston NIC, Cisco 340 ISA card (for highpeed wireless internet access). OCZ Monster2 cooler, Radio Shack white stuff.a CPU temps upper 30's at idle, low 50's with heavy load. Case always open her in hot Arizona.
Thanks,
Gene

Welcome to the forum.
You are running at 112 MHz. The non "a" version motherboards are not set up to do 133 MHz. This is not to say that there are not any mods or tweaks that could make it go that fast. I just do not know what they are. You would get a performance increase with the KT7a, but I do not think that it is worth it in your case. You have some good stuff in there, I would wait until something that is a bigger jump comes along.The best tweak you could do now is a better cooler, maybe water cooling.

Your mem is running at fsb+pci or 112+37= 149mhz.
(pci = fsb/3) IMO you will gain nothing by getting the [A] version. The only diff will be the actual fsb speed, and since this bus is ddr (dual data rate) it is not a bottleneck in AMD,s.

I had KT7, and swapped to KT7-R cause I was upgrading a friends machine. Didnt feel any speed diff actually.

I think you will see a performance gain from switching from the KT7 to the KT7A board. You are running at 112mhz FSB right now, which I have to say is pretty good for that board. I have the same board and I can't get about about 107. With the "A" board you can get a much higher FSB setting. At that point your limiting factor, I would say would be your CPU if it is of the 200mhz FSB variety otherwise it would be your RAM, but that is good.
