Tbird 850 to the MAX

[Guest]

How far would someone be able to take a tbird 850 to? What determines how far it can go. With artic silver II, the best heat sink and fan, pc150 curcial ram can you see any limit already? First thing I'd like to do is get the tbird running at 133 fsb around the same 850 clock. Next would be the 150 fsb around the same 850 clock and if everything runs stable try to maximize the mhz.

I've got a t-bird 850 on a kt7 and was able to take it to just under 1050 with a good hsf and arctic silver. I recently modded the voltage on the board and i can now get it to run at 1122 stable but it just won't go past that and my temps are up to over 50 degress C under load.

Can anyone tell me about how much more performance would be gain from these settings:

133fsb x 8= 1064
150fsb x 7= 1050
What are my chances on reaching 150fsb if I have 150mhz ram to go with the system? Has anyone ever done it?

Also, what voltage did you use and hat should someone use trying to get 150fsb?<P ID="edit"><FONT SIZE=-1><EM>Edited by m_kelder on 02/20/01 03:15 AM.</EM></FONT></P>

I'm using 2.2 volts right now, but it makes it more difficult to get the fsb higher with higher voltages. I dont have a kt133a motherboard so i dont know how easy it is to hit 150 fsb, but i cant get mine over 105 at this voltage compared to 112 at 1.85 volts.

 

[Guest]

Isn't the point to up the voltage is to reach higher clock? Or does voltage effect the multiplier as well?

 

[Guest]

Well, I can now reach a higher clock overall, but I have to do it with a higher multiplier and lower fsb. Some say that raising I/O voltage helps this, but I haven't noticed a difference.

 

[Guest]

Which has the highest performance output (assuming you have a rock solid system after overclocking)? Higher fsb and lower mhz or lower fsb and higher mhz?

i guess you are talking about the kt133a chipset.
faster fsb works better than just changing the multipliers.
try running a benchmark program at both settings. the higher fsb will give you a better result. the only thing to worry about increasing fsb is the strain to the parts. ie the pci card and agp cards. when upping the fsb, you are also increasing the pci bus and agp bus. the pci slot runs at 33mhz and 66mhz for agp. some motherboards allow you to change the peripheral bus speeds.

My slowest PC out of 61 computers is @1050Mhz

Yeah, when I finaly get everything I will be overclocking slow, testing every setting in 3dsmax4 rendering for a few hours. I excited to actually buy a chip that can render decently and that can be overclocked so well, say good bye to this crappy p3 500.

 

[Guest]

It's quite likely you'll end up stuck with a max fsb of about 145 mhz, anyway, go for the highest fsb you can and then care about increasing the multiplier.

There would be an important gain in 150x7 over 133x8, 1050 is higher than 1064...

Increasing the voltage of the CPU is not useful when you try to get a high FSB, it is better to increase the VIO voltage.

SEARCH FIRST, THEN POST

 

[Guest]

Cool, that was a great help. I didn't plan on going higher than 150mhz anyway.

Last time I checked, 1050 was smaller than 1064. =o)

What's a signature? Oh, those words that show up after all my comments? I don't need one of those!

 

[Guest]

which motherboard support changing the fsb for peripherals? Also, any idea on how much performance is gained running at a higher fsb than higher multiplier?

 

[Guest]

My old BX based ASUS P2b changes the PCI divider to 4 when raising the FSB to 133 Mhz. So alot of MoBos can probably do this.

 

[Guest]

yeah I found out that most do it
