![]() A guy I know gave me a box full of motherboards that were bad or going bad. This one just so happened to have an Athlon XP 2200+ installed in it. Only thing I could spot wrong with it was a potentially fried DDR RAM slot, and an OST on the VRM high that got so hot that the sleeve shrunk. Interesting how they used 16V caps for 5V in for the VRM. Probably just for the lower ESR. Just sitting at the BIOS, the exterior of those VRM high caps got to 63C. That's pretty warm...Besides the VRM, all the other caps on the board are GP.

![]() I have its older sibling the M6VLQ Socket 370 PIII Taulatin supported. It to was loaded with OST RLS caps. Tiger Direct specials.

Yes, they likely used the 16V caps for lower ESR. My JetWay N2PAP-Lite was like that too, except it used GSC ME caps ![]() By the way, this is the first BioStar motherboard I see with more than 5 caps for the VRM low side. Those empty spots look ashamed. Fill 'er up ![]() My vote goes for Panasonic FR of FM. Or even Chemicon KZE / Rubycon ZL will work. Save your valuable HM. HN, and HZs for something else that needs them. Those old Athlons run at 1.6V core or thereabouts, and they don't consume a whole lot of power, so it takes for quite a bit of ripple to appear on the VRM low side before things go bad. That's how they got away with using nearly general purpose crappy caps back in the days. Quote:
That said, there would be no harm from using very low ESR caps on these boards. In fact, even polies should be fine. I bet that burned RAM slot was a result of either somebody trying to remove the RAM while the PC was plugged in, or just those crappy OSTs. Quote:
Wouldn't it be cool to set up a retro gaming cafe with these old boards one day? Like, maybe 10-20 years from now? I bet they would still work like a champ. Last edited by momaka; 02-04-2015 at 07:29 PM.. |

Here's something interesting to note from a little experiment I did. With the exact same scenario (Just sitting at the BIOS) with the same PSU and ambient temperature, before and after the recap, the CPU idled 4C cooler afterwards. Quote:

![]() By the way, I used our simple little voltage trick to get the CPU fan to run much cooler, but still be adequate

![]() ^ 7V trick? I have that on a few "misbehaving" loud PCs as well

ESR *appeared* in spec, but the capacity on many of them was high and lingering on the border of +20%. I think one or two were above that. That tells me they were likely becoming leaky and ready to go soon (and GO they did ![]() That's how early Nichicon HN and HM from the defective batches seem to have failed. Quote:
I guess this further proves that OST hate the heat. Quote:
Also, if I am not mistaken, on old boards like these, CPU HALT instructions aren't loaded until the OS kernel is. So what you are seeing may as well be the maximum that board will pull. And if not, the power draw under max CPU load won't be much higher than that. I'm not sure which 2200+ you had, but here are a few: http://www.cpu-world.com/CPUs/K7/AMD...2200DUV3C.html http://www.cpu-world.com/CPUs/K7/AMD...2200DKV3C.html You can see that the minimum and maximum power draw are about the same.

![]() I have a 1.4 GHz Duron Applebred that also runs very cool (due to 1.5V core). But it only has a lame 64 kb of L2 cache ![]() Man, when I got that back in late 2003 and was able to play Half-Life 2, I was totally like this: ![]() Quote:

I have 3 of them (20 GB, 40 GB, and 60 GB). They all have a few bad sectors, but they have "settled" for a while now. Last edited by momaka; 02-04-2015 at 09:49 PM.. |

I think the second loudest PC I have is my HP NetServer with its 10k RPM Maxtor Atlas HDD. I believe that is a ball bearing design too. The CPU fan already has the 7V trick and I removed the rear 92 mm fan, which was some DC Koala (or something like that) brand that is rated for several watts and is extremely loud on 12V. PSU is made by Astec, and the 80mm fan in it is quite loud too, even though it does have a thermal controller. Quote:

![]() Only on the 40 GB - 15848 hours. The 20 GB might have more. The 60 GB had few IIRC. I need to update my HDD SMART logs. Quote:
I actually did a YouTube search, and people with similar setups were indeed able to run MW3. Granted most did it on 800x600 or lower and all settings on low... but I still find that impressive. When Half-Life 2 first came out, my PC had *only* 256 MB of RAM, so I could only run the game at 640x480 and med-low details. When I upgraded to 640 MB, it felt like I had unlimited RAM ![]() ![]() That's with an Asus Radeon 9200 SE (stupid edition?) 64 MB video card. Fun days ![]() Last edited by momaka; 02-06-2015 at 12:58 PM.. |
