Friday came and went, but the photos we are itching for are MIA.
Any chance you'd be able to test this out in a dual CPU socket 8 system? Which socket 8 systems do you have at your disposal? I thought having a dual PIIOD-333 on my dual socket 8 setup was pretty slick, but a Tualeron at 933 MHz blows that away.
I just looked in my bin for a PL-370/T, but I just have the Powerleap PL-NEO/T. I used to use these in a dual Asus board that didn't have Tualatin support. So the PL-370/T would be similar to the PL-NEO/T, except the former has voltage control and AGTL circuitry?
I only posted this yesterday, so Friday is still ahead 😀 Unfortunately, I am out of town until then.
I am currently running it on a pretty unimpressive QDI Legend P61440FX Commander.
And I do have a dual Socket 8 Intel board (will look for the model number when possible), on which I still need to test it. This board did work with two Mendocino Celerons @ 533 MHz. However, these are known to support SMP, which is not the case for the later Celerons, including the Tualerons. Actually, among the PIIIs, I believe only the full Tualatin-S models can do multi-CPU. And with these in such a system, the lower multiplier would result in quite low CPU clocks. Still certainly much faster than the PII-OD. For the Coppermines (Celeron or not), it seems that they cannot do SMP either, but I have read conflicting information and some forum post claimed it did work on some models (great reference, I know..). I doubt it, since Intel probably didnt want to cannibalize their first Xeons.
My own experience until now: I think, I already wrote earlier that I had modified the PL-Pro/II to run FC-PGA up to Coppermines. This did not work in dual socket configuration, neither Celeron, nor full Coppermine PIII. With only one CPU installed on the dual board, no problem. I must admit that I didnt pursue it much though. Also, I honestly prefer the older, more down to earth QDI motherboard vs the Intel one (AT vs ATX, no onboard SCSI and LAN etc..) and both are catastrophically bottlenecked by the EDO RAM anyway 😀
Unfortunately, I have neither two PL-370/T, nor two identical Tualatin-S models, but I will try it with my single Tualeron and a 1400S (unfortunately not at the same time) in the dual socket board and report asap 😀
Regarding CPU compatibility, the PL-Pro/II supposedly is not supported by Award Bioses (acc. to the PL website). This is not true, but I absolutely needed to run Biospatcher first, otherwise no post.
For the PL-NEO/T, I cannot say. Again, modifying the socket of the PL-Pro/II to accept FC-PGA (i.e. isolating/connecting the Reset pins) did work up to Coppermine, but the Korean modified "FC-PGA"-Tualatins did not run at all. So I dont know if further mods would be necessary to make the PL-NEO/T PPGA- or PL-Pro/II compatible as well.
