How to over clock a pentium classic when you don't have the owners manual to the board....(or even the brand name)
Pentium Classic (Pentium 1, pre MMX)
currently running on 133mhz. Intel approaves of 200Mhz for the Pent 1. I've reached 266 earlier this week with a socket 5 board.
no jumper for bus speed, or CPU speed. but maybe someone out there can help me rack my brains.
What we have to work with:
Socket 7
Voltage Jumpers
current options (133Mhz settings are marked by *)
=========================
| CPU TYPE | JP1 | JP10|
-------------------------
| P54C | | OFF | ON |*
| 6x86 | K5 | OFF | ON |*
| 655C | | ON | OFF |
| 6x86L| | ON | OFF |
=========================
===============
| JP9 | VCC_3 |
---------------
| 1-2 | 3.30 |*
| 3-4 | 3.50 |
| 5-6 | 2.80 |
| 7-8 | 2.50 |
===============
| CPU | JP8 | JP7 | JP6 |
----------------------
| 50 | 2-3 | 2-3 | 2-3 |
| 55 | 2-3 | 2-3 | 1-2 |
| 60 | 1-2 | 2-3 | 2-3 |
| 66 | 2-3 | 1-2 | 2-3 |*
| 75 | 1-2 | 2-3 | 1-2 |
| JP3 | JP2 | Ratio |
--------------------
| ON | ON | 2.5x |
| ON | OFF | 2x |*
| OFF | ON | 3x |
| OFF | OFF | 1.5x |
(Other Jumpers)
JP5 (N/A - no pins)
JP11 OFF (Stencel Note: Cryix = 0N, else = 0FF)
JP4 [1-2]-3 (Next to CMOS = Cmos Clear jumper?)
Now with the CPU set at 66 and the 'Ratio' (Multiplyer?) set at 2, that give me 133 (roughly)
If i set the CPU to 75 and the Multiplyer to 3 then that'd put me up to roughly 225. What do you guys say? should i give it a shot?
Should i lower JP9 for less voltage to watch my temp?
IF i set it from 6x86 to 6x86L how would that effect my proformance?
How would i set the board for a 500 mhz chip? i don't see a combination for this.
egerly waiting the mass's opinion.
