Got a Tillamook 266mmx working at a ECS P5SJ-A SiS 5598 motherboard. During post the bios says 512kb cache and also in programs like everest in win98se it says 512kb cache enabled.
I also did some benchmarks in everest and compared to my Asus TX97/233mmx setup and the tillamook is indeed faster in most tests so everything works fine.
I needed to do the pinmod to get the 4x multi working. This board has a 4x setting but it did not go any higher as 3,5x. After the pinmod it now works at 4x.
This board also runs fine and stable at 75fsb to give it a nice 300mhz speed. 83fsb can also be selected and i will test that later.
Only downside is this board has only 72pin memory slots so Edo only. This chipset can cache up to 128mb so that is a big bonus! I'm running 98mb (2x 16 + 2x32) right now as i have no more 32mb Edo ram sticks and it scores the same as with 64mb. This board goes as low as 2,1v so that is fine for the 1,9v tillamook, unfortunately the i/o voltage is still at 3,3v.
I did also test this cpu on an Asus TX97-XE (Intel 430TX) but no sigar... also did test it on an Atrend 5030 Intel 430TX board and with this you can see voltages in the bios. Using the tillamook it showed 2,5v io voltage while with a normal 233mmx it showed 3,3v ! So the TX does respond differently to the Tillamook? Unfortunately the L2 cache got disabled as well on this board so the SiS board seems like the fastest option.
Member Kanecvr said that a Tillamook runs fine on an Aopen AX59-pro with cache enabled and if that is the case that would be the ultimate board for this cpu (100fsb and agp). Mine however didn't even boot with the Tillamook. I will look further into this and maybe i need another bios file or something. @kanecvr : What is your board revision and bios revision?
I also tested this cpu on 2 Epox mvp3 boards and one DFI mvp3 board. Also grabbed 2 Gigabyte Ali V boards, one Jetway and 3 different Asus Ali V boards but none of these super 7 boards worked.
Some didn't even boot with this cpu and others did disable the L2. I know they all work fine with k6 cpu's so these boards are in working condition.
Still have one SiS, one 430TX and one 430HX to test....... But i am pleased that atleast the ECS P5SJ-A works!
