Looking for PCIE LVDS card for Agilent MSO Infiniium scope
<< < (4/4)

So after finding a drop in 7x5mm 14.318MHz on mouser, I ordered that with some new 18pF caps.

Replaced the crystal and caps, and guess what, its working! Touchscreen is also fully functional.

While I had it open I also did some upgrades...

CPU: From Celeron D 341 >>> Pentium 4 660 (also upgraded cpu cooler from intel all-aluminum to copper slug version).
RAM: 512 MB DDR2 533 >>> 4 GB DDR2 533
HD: 40gb 7200 rpm drive >>> 64gb Intel X25-E SLC SSD

System is much faster now. As fast as it will get with the stock mobo anyways.

Time to play with GHz signals!

After you replaced the Celeron D 341 with the Pentium 4 660 on the Intel D915GUX motherboard, did the BIOS have an option to enable or disable Hyper-Threading on the Pentium 4 660, or did the BIOS hard code Hyper-Threading to be enabled or disabled? I wonder if there would be any noticeable performance difference at all with Hyper-Threading enabled vs disabled.

My 16901A logic analyzer with the Intel D915GUX motherboard came standard with a slightly faster Celeron D 352 (3.2GHz Cedar Mill processor with 512KB L2 cache, vs 2.93GHz Prescott processor with 256KB L2 cache for the Celeron D 341). There would be less of a performance difference replacing a Celeron D 352 with a Pentium 4 660 than replacing a Celeron D 341. Still, I might give it a try just for the heck of it (or maybe a Pentium 4 650 which has a lower TDP)

Hyper threading was turned off in bios when I popped the P4 in.

Out of curiosity i turned it on. System booted just fine, but the Infiniium scope app would not open and kept crashing. Something about HT is not compatable with that. So I just turned it back off in bios again and everything is happy.

The 2MB cache in P4 might be a nice addition. FSB might also run a little faster. It was a pain to remove the cpu in my unit though; the heatsink had hot snot on mounting points from the bottom of the board. I had to unscrew and lift the motherboard up to get the glue off. The original ram sticks were also hot-snotted on the latches, so had to carefully peel that off too. Not sure if your logic analyzer has hot snot on the ram, cooler as well.
