Current specs:
- PIII-S 1400 - modded; connected AM34 with AK36, AK26 with AK4, ; isolated AN3, AJ3, AK4. Also connected AM36 with AL37 (vid1 with vid2) for greater voltage - i checked this connection by the multimeter on the back of the motherboard, so i`m sure that cpu has higher voltage.
- Asus CUV4X-CME/MEDION2001
- 2x256mb SDRAM - infineon CL2 and twinmos CL3. Both works stable with 2-2-2-6
- MSI/MEDION TI4200
- Audigy 2 ZS
- WD 80GB/2MB
I cannot get greater fsb than 142. I think i tried everything. PLL chip is ICS 9248-98, same as Asus CUV4x-M, but on CME board i have to use CPUFSB app for editing fsb. This maximum stable fsb (140, PCI 35MHZ) is a wall for all of variants that i have checked.
Variants:
- two different disk`s
- two diffrenet modded cpus - before PIII-S 1266
- two different GPUS - before MX440
- reducing ram timings for 3-3-3-7
- trying with only one module of ram
- increasing ram access latency (i don`t know what is it exactly) to 2 ns
- changing ram multipler - so when CPU has fsb 133, ram has 100
- removing soundblaster and disabling onboard soundcard
- disabling one of the IDE connector
- disabling com and lpt ports
- using bigger cooler for socket 478 with 60mm fan
Also, i noticed that with fsb-142, superpi-1M can be passed, but usb mouse and keyboard freezes. What else can i try? I wonder if original CUV4X-CME has more options in BIOS but didn`t found any info, and i don`t have any floppy disk.
