I've looked around this forum for a solution to my problem, but I haven't been able to yet, my AMD Athlon XP 1800+ won't run at 1.53 GHz.

My mobo is ECS K7s5a.
I have 2 x 512 mb SDRAM Kingston ValueRAM PC133.
I have a GeForce3 Ti200 128 mb.
I've updatet the BIOS to the newest version (10.29.2002), some few new features are now available.

I've looked into my mobo's features;
I can't change the VCORE voltage,
there are no dip-switches or no jumper settings I can change to make the FSB go from 100 MHz to 133 MHz.

I can change the FSB in the BIOS, and it runs at 1.53 GHz, but when I start playing any game, whether it's Freelancer, Black Hawk Down or Postal 2, it crashes about 5 minutes in the game, there's sort of a scrath in the sound, and the screen freezes, so I'll have to restart it.

Why is it doing this?

I'm thinking 2 resons:
1) I need a new fan, coz the AMD processor gets a lot hotter than other processors.
2) I need some new RAM, but the Kingston I have, should be good enough.

Thanx for your help!

probably heat related

Hey

I have seen this prob before. Some boards are screwed out of the box, and refuse to run at 133fsb

Take it back to where you bought it from.
It "may" also be your memory. But usually memory will fail (if it has a problem) at 100 or 133fsb regardless.
Try one stick at a time.

I had a similar problem with my bios, istead of running my Athlon XP 2100+ Palomino at 133FSB in the bios I had to put it at 166FSB and then it ran at normal speed, updated the Bios and now I have to set my FSB in the Bios to 133 FSB for it to work correctly, and this a new mobo KT3-V

Just try putting your FSB up a little do it in 2 - 3 mhz increcments and see if that makes a difference, it could be that the BIOS is screwed up as mine was, but newest BIOS fixed the problem, but as you said you got the latest BIOS

PS: if the PC does not start up after setting the FSB higher than 133FSB, clear the CMOS, there should be a jumper onboard somewhere, should be in the manual

Goodluck

Thanx for your replies.

My PSU is a Codegen 300 W

I checked my fan, there's nothing but a name on it,
it's a Titan, I checked their website
www.titan-cd.com and found out it's probably the
one called TTC-D5TB/E

I read somewhere that I have to set the CAS
Latency in the BIOS, it has something to do with
the RAM frequency??? I have 3 options:

SPD
2T
3T

Which should I choose?

spd will automatically set the memory to what it is supposed to be rated at,providing you have spd memory, it easy enough to know if you have it. just check for a tiny 2mm chip on the left or right of the memory
not sure about 2t 3t

From what I've read and went through, ECS did a cheap job mounting the heatsink on the SiS735 Northbridge chip. They used a doubled sided tape that doesn't allow proper heat transfer from the chip to the heatsink. I removed mine and put a layer of thermal paste on the chip itself and replaced the heatsink with a better one w/cooling fan attached. My board (ECS K7S5A Pro Rev. 5.0) didn't crash during use, but did fail to post most of the time if the FSB was set to the correct speed for my XP 1800+. Well I wasn't about to run at 1150Mhz. Anyway hope this helps.

I bought a new fan (Global Win TAK58)and tried it out. It's actually worse than the one i already have. It should be able to cool up to 2700+ or 1.7 GHz, but it isn't. I used CPUCool to see the temperature, and after i changed the fan it was raised by 5 degrees and my PC froze after fewer minutes, so I'm positive it's heat related. I switched back to my original fan and it works! BUT with the cabinet open. As soon as I close it, the temperature goes over 50 degrees (I think) and it freezes (when I check the BIOS after reboot it says 52 degrees). My cabinet is made of aluminium or some other metal, I think it holds the heat inside. Can you recommend a really good fan for the AMD Athlon XP 1800+, one so good I actually can close the cabinet?

Thanx in advance

There's a problem with this board and 2 sticks of SDRAM (PC133). I read about it on multiple web groups and I also know from experience, I had the same board with 2 modules of 256Megs SDRAM and I had a lot of crashes in 3d games. I couldn't figure what was happening, I thought it was a heat problem. I changed my case to a nice Antec, put some Arctic Silver on the CPU. Temperature went down from 55-58 C to about 45-48 C but the crashes were still there. A friend pointed me to the 2 SDRAM module problem and I just removed one for test. My problems went away, so that clearly was the issue in the first place. I didn't like running just 256 megs of RAM so I thought about solutions.
Finally I just got rid of the SDRAM modules and moved to DDR. Luckily the price of DDR is going down and PC133 is going up so I made the change without loosing to much. Try this one to see if it works for you. So don't go out of your way spending a lot on cooling parts when that might not be the problem
