Re: Point of View 7300GT gfx card recap
It's an AMD Athlon II X2 270, if you're wondering. It's got an Arctic Cooling Alpine 64 Plus on it, which, thanks to the FDB fan, I can run at full speed without it getting noisy. I think I have the motherboard's "Smart Fan" settings at a target temperature of 50 degrees (C), and a minimum fan speed of 50%. I have the cpufreq governor set to "conservative", so it only runs at 940 MHz when idle. It can be interesting to set the governor to "powersave" (locks it at 940 MHz) sometimes, just to see how well various programs run at that speed.
I'll admit that AMD's drivers are no good, but I've never had any issues with the HDMI out. It works just as well as the others for me, and I've had two cards with it.
As for those drivers, once I got a Radeon HD 7790 and installed it. The 7790 has its own driver, so I installed that. The first thing that I noticed was that my mouse pointer was about four times its original size. Everything else worked fine, though. Later, I installed my 6570 as well (so I could use OpenCL on both at the same time). I did not connect them with CrossFire or whatever, as they're too different, and my 6570 doesn't support it anyway. When I turned the computer on, it crashed. I had to remove the 6570 (leaving the 7790 installed), remove the driver, reinstall the 6570 (so both were installed again), and install the generic drivers. Those drivers worked with both cards, so I'm not sure why the separate 7790 driver even exists.Last edited by cheapie; 11-07-2013, 11:43 AM.Comment

Re: Point of View 7300GT gfx card recap
It's not silly at all. I don't care if AMD came up with a die that can withstand 9999999C... those BGA joints that hold the chip down to the PCB will still break when the delta T from the thermal cycling is too great. And the hotter the chip is allowed to run, the greater the delta T. Also, the lead-free solder is NOT helping it any either!
Most hardware nowadays is built like shit. No considerations at all for proper cooling or any other features to make the device last.
So yes, like mockingbird, I anticipate that the next Xbox will indeed need lots of reballing and reflowing. Maybe nowhere as bad as the older 360s, but still enough to keep repair businesses happy.

Doesn't really matter. What failed most of the time on the original Xbox 360 was the GPU BGA not the CPU. And the GPU was made by... ATI/AMD. Not really ATI/AMD's fault though. The GPU heat sink was just plain shitty.Last edited by momaka; 11-07-2013, 11:36 PM.Comment

Re: Point of View 7300GT gfx card recap
shovenose -I believe that "silly" is not noticing the whole industry goes with the design for the dump (eg. planed obsolesence). THAT is, my fried, silly.Just because newer graphics cards are more powerful doesn't mean they are planned to break. That is silly.
Even "silly" gal can figure that out - check this video out and edicate yourself, you gonna need that:

It's a bit biased... Romanian site, Romanian customers, with low wages, majority bound to buy budget laptops that aren't necessarily designed to last... or used laptops...
Fact is AMD/ati cards don't really have a history as much as nvidia has (all that fiasco with weak underfill and poor solder on the gpu chips)Comment

Re: Point of View 7300GT gfx card recap
No, that's just the RAM BGA going bad. Both Radeon 9500/9700 and 9800 had this problem. Not sure if this was a screw up on ATI's part making the RAM chips run too hot or a manufacturing fault. Those cards used leaded solder so they should not have had these issues. A reflow fixes them most of the time, though.
The GPU of the Radeon 9600 uses a newer die that runs much cooler, and also slower but cooler-running RAM so that's why it won't have any heat issues. However, funny thing is, the Radeon 9500 still outperforms the 9600 despite being older an a "lower" model.Last edited by momaka; 11-26-2013, 12:46 AM.Comment

Re: Point of View 7300GT gfx card recap
That's because the Radeon 9500 (and Pro) was essentially a clocked down version of the R300 (Radeon 9700/Pro) with its memory interface bus width cut in half and the same for the amount of (locked) rendering pipelines on the 9500. The 9600 only had half the amount of rendering piplines (for texture mapping, vertex and pixel shaders, and rendering otherwise) and lower memory bandwidth. The 9600 Pro did have somewhat superior memory bandwidth over the 9500 Pro, though, but that only really helped it in synthetic 3D benchmarks (and even then it was largely outclassed by the 9500), which doesn't mean much of anything (especially considering how much nVidia cheated with their drivers back then, in order to make their GeForce FX cards look "comparable" to the 9500-9800 series). It could help a tad in games that use more traditional methods of rendering (texture operations) rather than shaders, but even then those were starting to be phased out.
If you read the old reviews of the 9600 Pro and compare it to the 9500 Pro, there really isn't a single situation (3D rendering in games) where the 9600 Pro does better, much less even equal the 9500 Pro. The R300s were all so far beyond their time that even within 4 years of their release, they could still play the newest games at decent settings. I didn't realize the 9600s didn't run as hot, though - that's definitely a good thing (in my experience, however, the R300's BGA RAM chips only run very hot in 3D rendering and aren't even warm to touch in 2D operation). I'd guess the R300 fails because its core and RAM chips are of the BGA package and it isn't -that- tolerant to large temperature swings (flexing, though still much moreso than leaded solder). Some of the stock models also had shoddy thermal paste and an ADDA hyprobearing fan that would eventually seize (expediting the failure).
I would say nVidia's problem with the underfill is a little more perturbing than even the worst of ATi/AMD's driver, issues, catalyst control crap, and whatever else. nVidia knew about the underfill issue with the GeForce 6xxx-9xxx series of cards and lied about it through their teeth. It's too bad that problem plagued upon the 8800 GTX/GTS cards as well because while those gigantic beasts ran very hot they, like the R300s, were beyond their time too as far as performance goes.Comment

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

I've been seeing a lot of cheap-looking (but not always so cheap) no-name AGP video cards on eBay for a while. They started popping up quite a bit when the market for AGP cards became more alive all of a sudden due to interest in “retro” PCs. One thing that struck me about these cheapo cards is that they almost always seem to come with garbage caps - including the abominable Sacon FZ. That aside, though, I've been wondering about the rest of the quality (or lack of?) on these cards. So I decided to satisfy my curiosity yet again.
This one was actually suggested to me by ChaosLegionnaire.... -
Aaaaand… we have more retro-PC nostalgia repairs again.
This time it's with a XFX GeForce 6800 XT AGP video card. The XFX model number is PV-T42K-UDE3.
As with many early XFX cards, crap caps are the main issue here. The first one I bought and recapped was back in 2017. I've been meaning to post about it for a long time, but never got around to it due to the card needing a better heatsink/cooler to test it fully with the recap (more on that later on.) In the meantime, I acquired a 2nd one of these cards not too long ago (February.) Not like this makes any difference. Both... -
Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
