ECS K7S5A + AMD XP 1900+ problems with FSB stabili

[Guest]

I have the ECS K7S5A mainboard and the amd athlon xp 1900+ and i can get it started but it always hangs after i get started. this is in 266 fsb but when i take it down to 200 fsb it works fine without any hangs.. what am i doing wrong this is the 2nd computer ive had do this... PLEASE HELP

Read the last couple of posts that had the same problem. You can also head over to <A HREF="http://www.ocworkbench.com" target="_new">http://www.ocworkbench.com</A> and go to their ECS section of the forum...they have some helpful FAQs too.

Could also be your power supply, the CPU requires a lot more power to run at 133MHz FSB.

What's the frequency, Kenneth?

i have a 300 PS so i dont think that could be the prob.... i have 256mb pc2100 kingston ram, WD 40gb 7200, tnt2 m64 VC i cant figure this out... i have a thermaltake volcano 6Cu+ and the temps are very low so i dont think it could be temp probs... why isnt anyone else having this same problem??? would it be better for a next computer to buy a 200MHz FSB processor and set it to 100/133 that way it wouldnt bring down the freq??? this is sooo confusing... thanks for all your help

is enlight a good PS???

 

[Crashman]

Enlight is good, 300W is marginal, so you'll need to check your voltage, especially CPU Vcore and 3.3v, under load. Vmem also if you can. Alternatively, you might need a BIOS update. In the worst case it could be a bad board, which entitles you to a free replacement.

What's the frequency, Kenneth?

 

[Guest]

what are your readings from the bios on voltage???

 

[Crashman]

I have mine modified to 1.85v, and it's operating at 1.84v.

What's the frequency, Kenneth?

 

[Guest]

here is how my levels go...

Vcore 1.744
Vcc2.5v 2.488
Vcc3.3v 3.264
+12V 12.480
SB3V 3.488
-12V -11.885
SB5V 5.107
VBAT 3.488

 

[Crashman]

That's not so bad for a full load voltage-then again, if that's a partial load or idle voltage, I suggest you run a program that loads the system and check to see how much the voltage changes.

Some people in another website (the one I mentioned) blamed the overheating of the chipset when the fsb was set to 133/133 to be the culprit of random lockups and reboots. With the first revisions of the board (I'm not sure about the newer ones), there was no thermal paste between the SiS735 chipset and the heatsink. Some people have solved their FSB problem by adding some thermal paste between the chipset and heatsink. You might want to do the same.

[Guest]

would it be worth it to do the thermal paste and a chipset fan on the HS???? how hard is it to get the HS off the chipset.. i deff dont want to put a hole in my mainboard.. if i cant figer this out im just gonna send it back and get a diff MB.. this is toooo much work... it shouldnt have these crazy problems.... ud think that they fixed this stuff before they shipped it.. ohh well... thanks

you mean using thermal adhesive...
there are no holes to mount a different heatsink...
but you can buy some arctic silver adhesive, or some jbweld, and put a different heatsink, or put the same one on.
as far as i can tell, they are put on there with some sort of thermal tape...it is pretty cheasy thermal tape tho...as if it was too thick...and not actually doing anything..
another thing you could do is get a small fan, and put it on the heatsink, it MIGHT helpa little bit...

Yes, someone was having the same problem <A HREF="http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=498991#498991" target="_new">here</A>...i gave the same advice and he said it solved the problem.

I have this board with a 1.2ghz, it ran fine until I put a 7200rpm drive in, and then it started locking up and getting many blue screens. I had to disable the write behind cache (in file system performance) and the problems went away.

 

[HonestJhon]

it might be your powersupply , since the board is sensative to power issues, and a 7200rpm drive will take more juice.
check into that...and you might be able to re-enable that.

300W is marginal

Yep. I figured at 350W to be safe for an XP1600 system, so I got a 400W. No probs.
