Re: Poly modding an old Shuttle, question about non-VRM caps.

It's the 45W version with 1.45 vCore, AXMH2500FQQ4C. I'm running stock speeds on the X800.



What? Nahhh, no way it's pulling that much. The desktop 3200+ is rated at 76.8w TDP at 1.65v vCore[SIZE="1"][1][/SIZE]. I'm running a tenth of a volt less than that at the same speed.

I hooked up the Kill-a-Watt last night to get some ballpark power draw figures. After a brief heart attack moment where it kept crashing and restarting in the middle of 3DMark (which turned out...

Re: Poly modding an old Shuttle, question about non-VRM caps.

Thanks for the additional information, momaka.

I've been meaning to update this thread with my results. I finished the recap at the beginning of last week, but still wanted to finalize the build, and then I spent the weekend stress-testing it.

For the motherboard, I wanted to go full poly on it, but luckily common sense reasserted itself when I started pricing everything out, and I wound up doing polies on the VRM and FRs everywhere else.

Re: Poly modding an old Shuttle, question about non-VRM caps.

Thanks for the replies.
I'm not married to the idea of poly modding it, I just figured they'd last longer. This is an Athlon XP, Nvidia chipset, and high-end video card (probably gonna go with a Radeon 9800 or X800) all crammed into a tiny box and cooled by a single 80mm fan. Polies are supposedly more heat tolerant, and I certainly don't want to have to do the same work twice.

From what I was reading, 8-10 turns was the indicator for a low frequency VRM. If 6 is a better rule of thumb, I'll keep...

I've recently acquired a Shuttle XPC SN45G. Being an old Shuttle, it's littered with several types of OST capacitors, which would be 15 years old now and due for replacement even if they weren't complete garbage. Fortunately, it still POSTS, so hopefully I got to it in time.

I've seen these rightly referred to as cap bakers, so I figure why put electrolytics into such a harsh environment? May as well poly mod it.
I've mostly gotten the CPU VRM figured out, thanks to [URL="https://www.badcaps.net/forum/showthread.php?t=26745"]here[/URL] and [URL="https://www.badcaps.net/forum/showpost.php?p=175003&postcount=3"]here[/URL],...

Re: Sensor Readings - CPU Temp vs Core Temp?

The first number is probably Tcase, the temperature of the processor as a whole. Individual cores don't report their actual temperature, but instead the distance to TjMax, the temperature where the processor begins to throttle.

Depending on how your program is written, it could be passing this number along directly, which would result in the wild discrepancies you're seeing.
