Re: Jetway J694AS
I'm thinking about an Athlon 64, so I should have said any Socket 939 boards anyone had a good experience with?

Re: Jetway J694AS
I asked Jetway about the ECC thing, and they said...whoops our mistake, that board does indeed accept ECC. No real answer on the 32Meg x 8 other than that they sent me the .PDF manual for the VIA chipset I have so I could see for myself. But at least both emails I sent them were answered the next day, and the guy was really polite.
I talked to Crucial, and their tech support figured it was an ECC problem which was causing the system to crash with more than 512MB. They RMA'd my 2 sticks of ECC. I exchanged one stick for another 512MB non-ECC one, and returned...Leave a comment:

Re: Jetway J694AS
I just send a message to Crucial. They have a pretty good return policy, so if they don`t have any ideas on how to get both these modules working, I might have to return em. They guarantee the results of the Crucial Memory Advisor tool which showed my board as taking a maximum of 1536MB unbuffered SDRAM, but it`s not taking more than 512MB. Maybe they`ll let me return one stick.
Thanks AK0R, I`ll try looking into the Vcache thing. It`s worth a try at least.Leave a comment:

Re: Jetway J694AS
Thanks to everyone for the responses, you`ve given me a lot of ideas. I got a response from Jetway already. Here it is:
[B]Dear sir
1.The mainboard can't support ECC memory
2. The mainboard only support 8M/16M/ 32M x8 x16 type SDRAM module
so I recommend use 32Mx8x16 pcs 512M RAM module .
Please don't use X32 or X64 type SDRAM module ,
the mainboard can't support that .
Best regards

Re: Jetway J694AS
Yeah, I`m pretty much thinking it`s a hopeless cause, but I sent off a message to Jetway. Their site says they should respond within 3-4 days. I want to see what they have to say, and then I`ll try contacting Crucial.Leave a comment:

Some improvement
I updated the BIOS with the latest version from the Jetway site tonight, and now ECC is working! Also the system boots up faster.
But it still will not accept over 512MB of SDRAM. The system keeps restarting before Windows can load. I tried again with the 512MB x 512MB combo, as well as the 512MB x 64MB combo.
But I`m happy it`s working with ECC enabled now, and that the system is working nice with 512MB RAM. I`m just bummed that I can`t seem to put this extra stick of 512MB to use even though the specs of this board say it`s cool for...Leave a comment:

Re: Jetway J694AS
First I set the timings to 2-2-2-6 and it worked ok with one stick. But with both, it died. Then I tried setting to auto, again it worked with one stick, and when I checked in Everest it showed the timings at 3-2-2-6. But with both sticks, it died.
I`ve been thinking of updating the BIOS, since I noticed on the Jetway site, they have a more recent version from 2002 for my board. I also ran the BIOS agent from esupport.com, and it showed some interesting info:
It shows maximum memory: 512MB
Also says my chipset is: VIA 82C691...Leave a comment:

Re: Jetway J694AS
Thanks for the quick reply! No, I never changed the memory timings in BIOS. Not even sure how to do it. I`m in BIOS now, in the DRAM timings section and it currently shows:
CAS latency: [B]3[/B]
RAS Precharge Time: [B]3T[/B]
RAS Active Time: [B]6T[/B]
Activate to Command Delay: [B]3T[/B]
Bank Interleave: [B]Enabled[/B]
DRAM Drive Control: [B]Auto[/B]
The RAM I have is CAS latency 2, so should I change that to 2 in the BIOS? Also which of the three timing settings...Leave a comment:

Happy New Year!
Thanks for all the help! I`ve been at the in-laws the last few days for New Year`s(no internet), so I didn`t get a chance to post. I replaced the old caps, and it was not easy...I`ve got a lot of respect for you guys. I think I need a hotter iron, since this one`s only 20W. Removing the caps was hard, but the needle technique to clear the holes worked good. Anyway, I soldered on the new caps, put the system back together, and started it up. When I turned it on and it didn`t explode, I felt relieved, but when Windows booted up, I felt even better.
This...Leave a comment:

Re: Jetway J694AS
Thanks for the help! I went back today, and picked up some 1000uF 10v caps as well. Same KZE variety. I got a card from the guy there, and they`ve got a website. It`s totally in Japanese, but there are a lot of pics if you`re curious to check it out:

one more question
Every cap on my board is Tayeh. But they all look good except for the 1500uF 6.3v ones. Do you think it`s necessary to replace all the others such as the:
1000uF 10v, 470uF 16v, 100uF 16v, or the 10uF 25v ones?Leave a comment:

Back from Akiba
Searched all over Akihabara today, and couldn`t find a suitable used motherboard. I decided to give replacing the caps a go. I picked up a soldering iron for about $17.50, it`s a Hakko Dash(No.N453P). Supposedly, it heats up to about 430 C. I couldn`t afford the temperature adjustable solder stations.
I got some 0.6mm solder (too thin?). I couldn`t find any labels for 60/40, everything here was labeled by %. The one I got is 60% Sn, that`s tin right? Is this kind ok for soldering a mobo? It was really cheap, so if you recommend something different,...Leave a comment:

Re: Jetway J694AS
I got some important phone calls today, so I didn`t have a chance to go to Electric Town. Will go tomorrow. I checked out that MSI MS-6321 on the net, and it looks nice for me. I`ll keep an eye out for one tomorrow! Thanks again for the information.Leave a comment:

Thanks for the reply!
I`m American, from California. I moved out here early this year. I love it! But of course miss my friends back home...and the weather
. I`ll totally take some pics of Akihabara for you guys. Should I post them in here? Or in the Offtopic/Lounge?
You`re right about the VIA chipsets. The one on my current board supports 1.5GB of RAM.
Anyway, thanks for the quick reply, and for the good info. I`ll post back tomorrow night, and let you know what I found.
Just happened to me right now, too! I refreshed the thread before...Leave a comment:

To tell you the truth, I`m not sure
. It`s a Pentium III, and I was thinking it`s a Coppermine cause it`s 1GHz, but I`m not sure. I bought this system off my friend`s teacher a couple years ago, and he was the one who put it together. I`ve never removed the heatsink, either. As of about 1 year ago, I didn`t know a thing about computers (just use it for making music!), but this one`s been acting so mysteriously, that I`ve taken an interest, and have been learning everything I can on the net.
Anyway, to answer your question, I`d like to recap this board myself. But the thing...Leave a comment:

Jetway J694AS
Hi, this is my 1st post here. As I can see you`re all aware of the cap brand giving me trouble...Tayeh, but I figured I`d post anyway for more evidence. My computer has been giving me problems for the last year now. Started off once in awhile, then got progressively worse. Basically, restarting, failure to POST, etc. After trying everything else, someone suggested I check the caps. Sure enough, 5 of them are bulging (2 out of 5 leaking from the top)!
After doing some net searches, I found tons of info, and came across this site. I had no idea this problem was so huge, but I feel...Last edited by willawake; 12-26-2005, 11:43 AM.
