How do you overclock a Tyan Trinity 400 without a slocket?

[Left nut]

I have a Tyan Trinity 400 motherboard (via chipset) and a Slot 1 p3 600E. I've heard some people overclocking with this board even though its not known to be the greatest for overclocking. I just want to know how all of you who have a slot 1 cpu and this mobo are overclocking this combo. I'm using the newest bios 1.07. What settings do I need to change to get 800?

There probably isn't much to do. Find out how to increase the system bus speed (front side bus speed, or FSB). There may be jumpers or dipswitches on the board, or maybe there's something in the BIOS. On a Tyan there probably are not too many different settings. That's basically it, since you can't change the CPU's multiplier with a P3. Obviously if you want to do 800 with a 600 you've got to set the FSB to 133, which may be a setting on the board if it is a newer board (i.e., is not one of the early revisions 9900Y or 9900YA as indicated next to the PS connector).

To stabilize the system at whatever FSB you may have to increase the CPU voltage, but it may not be very adjustable, if at all, on a Tyan. Again, look on the board or in the BIOS. You may need to increase the CAS & RAS settings in the BIOS also, for stability when overclocked. You just have to play around with it, since their are no hard and fast rules as to what works from one system to another.

Read or download & read the manual. Remember that Tyan's are made, not for overclockers, but for professionals or enterprises who want stability and reliability in their systems and who decide what speed CPU is needed and then write a check for it.

My Trinity 400 overclocks very well but I am using a slotket.Go
into Chipset Features in your bios and CPU Clock/Spread Spectrum
is how to adjust your fsb,go up in small amounts,if it won't boot
at the new setting you will have to clear cmos.If you have 133 ram
set DRAM clock to HCLK and your memory bus will go up with your fsb.
Here is a good site for this mobo.

I also have a tyan but swapped it out for an ax63pro to overclock my p3550e slot 1.

Some of the older tyan boards had jumpers for the fsb but not on the newer ones thus the only way to have the slot 1 detect at 133 instead of 100 is by covering the pin #14 on the processor. I tried it with tape but it slides too easily so asked on the board and it was suggested to use nail polish. However I just swapped out the board.

The processor can be manually set for higher bus speeds but it wont switch over the agp multiplier so your card becomes limiting and the pci peripherals as well.

Good luck.

Blackhawk is correct. If you just set it in the bios to go to a different bus speed the agp/pci divider is not set correctly. You'll have to use a slotket or tape pins to overclock much on this board. It's pretty sad on overclocking out of spec (ie 75 mhz, 112 mhz, etc). Mine won't even go one step out of spec. Works great in spec though. Running a cb0 p3-700 at 933 (133 mhz fsb) using a slotket at default voltage and cl2 pc133 memory. It fails to even post if I try anything above 66 mhz (with a celeron that did and does fine at 83 mhz on an abit lx-6 for over 2 years) or 133 mhz.

This is the reason I bought the fc-pga p3-700... I read up on it and didn't feel like taping pins over using a slotket. The ability to change voltages using the slotket was also important since tyan doesn't support that either!

Just try telling your Motherboard that your CPU is a 800eb. THe jumper settings will be the same. When you enter the bios, curser over to the CPU speed, when you are on it, use the page up/page down keys to select. Your options should be 400, 600, 800, or manual. When I had my 550e in my Trinity 400, I had a huge 'dead zone' of bus speeds between 112 mhz & 133mhz. It would run at 133 mhz (733mhz) bus by doing this. Your big problem will be the lack of the ability to adjust voltage. Give it a try & see if your CPU will run at 800 at default voltage. You may want to add some case fans & a alpha or Golden orb cooler.
