Re: Managing Heat on Intel based boards

The Allendale E4400 runs really cool, with lots of overclock margin, so I'd guess something is wrong with the heatsink contact. It works fine for me with a low-profile aluminium-only Intel HSF.

Re: The 2020 Operating System Thread

9Front looks interesting - I might try it on some old Centrino or PIII-class laptop (I don't even have a working PIII laptop any more. Not that it matters, since I can get working Centrino laptops...

Re: The 2020 Operating System Thread

Linux for me on almost every machine, though some laptops may have a pre-owned/legacy Win 7 dual-boot that I didn't wipe off after acquiring them (sometimes just for BIOS updates, if I figure it...

Re: Indentifying caps on Biostar 945gz Micro775 se

I'm OK with 2 slots for DDR2 mobos, because 2 GB DDR2 DIMMs are readily available. It's a bigger problem in the DDR1 era, where a minimum of 4 slots would be required today to reach 3 or 4 GB -...

Re: Indentifying caps on Biostar 945gz Micro775 se

Northwoods idled warm, but didn't spike too much under load - the 65W S478 Northwood 2.66/533FSB/512k that I still have as a spare, also idles at ~41c. The HT-enabled 89W Northwoods with 800FSB idled...

Re: best cheap/free scores 1.1

Not free, but cheap:

Biostar 945GZ Micro775 SE mobo: ~$2 from local E-waste recycler
Allendale Core 2 Duo E4400: ~$1.5 from another local E-waste recycler

I had to recap 5x VRM caps (2...

Re: Indentifying caps on Biostar 945gz Micro775 se

FWIW, I had an Allendale Core 2 Duo E4400 2GHz/800 FSB/2M lying around in my spare parts bin, which works fine on this board and overclocks comfortably to 2.66 Ghz/1066 FSB with stock DDR2-667 RAM,...

Re: Indentifying caps on Biostar 945gz Micro775 se

Old thread, long bump up. I recently recapped one of these - Biostar 945GZ Micro775 SE, with 5 visibly bulged caps.

These were:

PCT11: 3300/6.3 KZG. Replaced by 1500/6.3 Rubycon ZL (not...

Re: Dell Precision 380

Old thread, but still relevant. The best Dell BTX systems seem to be the Precision T3400 and T3500 - they have pretty much bulletproof mobos with polymers in the VRM, Rubycons and Pansonic elsewhere....

Asus P5BV-E/SAS recap

Posting here to document a recap of an Asus P5BV-E/SAS full-ATX server board. It's about a decade old, and generally not worth the trouble to recap, except that it has an on-board LSI SAS Raid...

Re: best cheap/free scores 1.1

There were K6-III 500 and also some mysterious K6-II+ 450 or 500 near the EOL for Socket 7, for not much money new at Fry's c.2000. The II+ had on-die cache, but smaller in size than III - I think...

Re: The Hall of Shame - Badcaps Photo Montage

Athlon II X2s have K10 cores and are significantly quicker than K9-based AM2/2+ X2s. However, they're better in AM3 mobos with DDR3, and do fine in AM2+ mobos also.

That said, the Sargas K10...

Re: Gigabyte 8I845PE-RZ fried?

For the record, the Gigabyte 8I845GVM-RZ S478 P4 board is utterly reliable in my experience - it supports most...

Re: New Keyboard/mouse suggestions

Exactly the same symptoms here - it's fixable, but maybe not worth the time and effort for a $2 part. After replacing those two caps, I realized that I had better NOS replacements - the bypass...

Re: Reliable Sources for Nichicon MUSE Capacitors

FWIW, I've measured the tan(delta) of various Nichicon MUSE series caps including the flagship KZ, and they were average - around 1 to 2% in most cases. Some generic low-ESR caps from other...

Re: KZG - KZJ - Same Electrolyte

Re: The 2017 Operating System Thread

Nobody using Fedora? I'm at F25 x86_64 on most of my daily-use Core 2 laptops, with F21 or F24 on a few. Of course, I got rid of the stock UI/WM and replaced it with XFCE or LXDE. Lower-spec and...

Re: Carbon film vs metal film resistors

Correct - the greatest contribution to resistor inductance probably comes from the leads and end-caps. If they contain any ferromagnetic material (iron, steel, nickel, cobalt, etc.), their relative...

Re: Observations on cap composition and stability

Re: motherboard cap question

Panny FL doesn't fail easily unless there is a combination of heat *and* high ripple current, in which case it can bulge and spill some thick black goo. If they look OK, I'd leave all the FLs alone,...
