Asus T2P4 and Cyrix-PR166+ overclock?
I'm using an Asus T2P4 mobo with a cyrix pr166 processor and it's really a little slow. I'd like to speed it up, but am on a budget so I'd like to hear if it's able to be overclocked or something.
ok - i've tried a few things...
original setup: 2x66 = 133MHz
try 1 : 2x75 = 150MHz but blue screens at windows bootup
try 2 : 3x66 = 198MHz but no video or bootup beep
try 3 : 2.5x66 = 166MHz. seems stable.. but it's early days
I've stuck with the 166MHz now. How can I check what revision of the BIOS I have?
This is a great motherboard to oc.
I've been running a Pentium 166MMX for about a year at 208mhz @ 83mhz bus speed with no problems at all. NT, liked 70ns in memory settings. Win95 and Win98 run at 60ns fine.
I'm running bios version 207.01, it's a beta.
Memory bios settings:
You may need a good heatsink for the Cyrix. Try slowing the memory down to 70ns and see if your blue screen goes away.
For 83mhz bus, jumpers:
Tom's Hardware has great info on this motherboard. You'll need ver. 3.1 or higher.
What revision is your T2P4. If it is a revision 3.1 or higher,you can push the bus speed up to 83mhz given that your ram and add-on cards can keep up with a 41.5 mhz pci bus. I currently have this board in one of my systems. It has been running for almost two years overclocked. Right now it has a p-133 oc to 166. I have experimented with other processors from time to time. Last year I ran a k6-233 at 250 for a while and it was quite fast. Some time ago I ran a cyrix 133+ (110mhz actual) at an actual speed of 166mhz. It ran very fast, but got very hot, it was one of the first cyrix chips. At any rate check your board revision. I am waiting for the k6-3 so I can run that in this board at 456.6mhz, requires some modifications to the board, but they are minor.
Yeahman you can clock that chip...I had a 166+ L chip clocked at a 200+ on a 75 mhz bus forever, and now my parents are running it, I didn't even have thermal paste on it. or run rain or anything for about a year, and it got kinda hot, but after doing those two things it runs totally cool now, however it's never been unstable, just would get a tad hot before.
