Whats the highest multiplier you have reached?

Whats the highest multiplier you have reached
and still had the chip stable?
what was your Vcore, chip, and cooling.

22x on a 8rda with a tbred b 2100 @ 100fsb just to see if it would run stable @ default vcore @ 2.2ghz on a slk800 and tornado.

MHz speed = [FSB] x multiplier

FSB is more important than raw MHz relatively speaking so the lower the multiplier and the higher the FSB is better.

You need higher rated RAM among other things to hit high FSBs though.


So my guess is you simply lower the FSB as much you can and hit the multiplier as high as you can.


BTW all T-Bred B's and Bartons aveage 2.3 GHz so do the math.
MHz speed = [FSB] x multiplier

22x with 100 fsb on my 8rda.

c62THe reason I ask is because i am considering going dual and the mobo that I am going to use only goes up to 150 FSB so my only way to OC after that is to up the multiplier.

[c627627]

So your question is what is a guaranteed unlocked CPU that can overclock the furthest then.

Older DLT3C B (not A) which can't be guaranteed anywhere or any 2100+ B would be the answer then.

You are slightly FUBARed. Nobody figured how to enable Powernow on the AMD 760, or 760 MPX. Actually nobody bothered.:D Your only hope is the mobile AXPs. Those still can be pin modded and have fully functioning L3 multipliers.

Update, I did figure out how to enable powernow on the AMD 760 and the hack is 99% sure to work on the 760 MPX, same register exists on both. So now you can use locked procs and powernow them to whatever you want. :D ;)

Since my motherboard only supports FSB up to 150Mhz, I am using a 15 multiplier to get me 2250Mhz out of each of my Athlons (vcore=1.75). I think I could reach higer if I had better cooling (like water cooling), but for now this works well :)

2700+ running at 100x23 @ 1.65v - VantecAeroFlow

[ailijic1985]

what stops a person from getting a higher multiplier with a FSB around 150?
voltage
cooling
or just the limitations of the chip?

Well, a 24x multi at 150FSB would be around 3.6 GHz, well faster than these chips can go. If you can get to 2.4GHz you might be able to use 16x at 150.

thx everyone

You can use 24x and get 2400 on 100fsb, I have done it myself on a AMD 760 board (nonSMP).
