6800le 'Black Screen' - The Complete Guide: Identification, modification and reason

[Sh0rt]

Hey, i just wanted to thank all of you guys who helped build such an awesome thread! I honestly havent seen much thread about a problem that had so many tests, informations and answers to my questions!

I had a gainward card with the " | "4 8 470 6E" | China | OK-162/OK-66 (3) | 2 | BS after few months" caps. Which was absolutly right! It was my third card of that series all with the same problem after several weeks. This one was now almost 6 Month and started slowly getting BS...in the end it was so bad that i couldnt play battlefield for more then 10 - 20 minutes!

I then found this thread read a lot and thought i give it a try! My dad has all the equipment in the basement So i just needed to find a good cap...i took a 2200mf with 16V. The mod was done 3 Days ago and since then i have played about 10 hrs of BF2 without a single BS!

Thanks a lot to all the people who made this awesome thread!

Hi,

Thank you for info about you card and nice you got your card working

Yep... "4 8 470 6E" models will all (?) finally give BS, but can be successfully modded with added capacitor i.e. capacitors replacement is not required like many MSI-cards.

About your mod: What capacitor you used (Manufacturer, series) ? That info would give some idea about how good quality capacitor you added (=will it possibly deteriorate soon/in months/never.. )

I will check it later, i picked it up from my dads place has been working in electronics. They are from siemens, i am not sure about the series but he said
they should be low esr. But he didnt remember

Its been 3 Days more and still no black screen...testing exessive Q4, BF2 and NFSMW demo over the weekend

OK... as far as those are low-ESR the series is not so important - it should take long time before (added) capacitor will be ruined. Although, the original 'green' capacitors might (or will) deteriorate more when card is older, and I wonder the time required for that is depending on quality of added capacitor.

Hello

- A MSI version 1 card, with "4 3 470 6E" capacitors
- Both earlier proposed capacitor modifications have been tested, but not worked for a long time
- Without any modification maximum usable (=no BS) clock frequency was 420 MHz !!!
- After replacing "4 3 470 6E" with Chemi-con's PXA-capacitors (820 uF/6.3V) BS was removed !!
- A memory voltage could be raised at least to 814 MHz
- Case stydy confirms: A CARD EVEN VERY BAD CONDITION CAN BE REPAIRED USING THIS MODIFICATION

I have exactly the same problem (also the same card) - I did the enhanced capacitor and it worked for a few months then BS again, so I replaced it and it worked for a few weeks. Have repeated this a few times - each time the time it works becomes increasingly short, now it only works for around a day!

I am in no way qualified to perform the ultimate capacitor modification but my uncle is very experienced in this area - having replaced capacitors and other components in his job.

((Maybe some free GOOD quality replacement capacitor for 'Ultimate capacitor modifiaction' still available (see Ch. 3.3))

I was just wondering if you had any left? Thanks

Yep. MSI-cards (very first models) will work only for a very short period with added capacitor - your case proofs that 'theory' once again !!
