i have a PIII 550@616 right now. i tried to get it to run at 630 (5.5*115) but the computer is not stable at all. i can still post the machine, but after working with windows for a while, it will either hang or crash. should i try increse the voltage to 2.1 and see if it's stable or not. the other thing is that i don't have any extra cooling for my system and my Winbond chip on the board fried and i haven't take to to repair yet(will do so around next week) so do u guys think it's a food idea for me to increase the voltage to 2.1v to see if it's stable or not without any extra cooling!!
btw. i don't even have case fan, the only large fan in the case is from the power supply which is blowing stuff out of the case!
Sounds unwise to fiddle with voltage at this time! May be OK, but you don't quote current temp inside your case. "GET MORE COOLING" would be my advice, since upping the V's is definitely gonna up the temp!
Increase V by 5% to gain less than 4% speed hike on a system (with one fried component)that's not "stable" at the moment, knowing that the resistance is the same and that the temp, therefore, WILL increase?
I call it risky. Case fans are super cheap! Maybe if you got 1 more fan the system WOULD be stable at 616MHz!
I just got mine there! I had it at 110fsb with no extra cooling for about 2 months now. I could never reach any higher with much stability, but thought it was the ram (hadn't played wit latency though)
Got new ram in there and have:
P3550 - SL3F7 (that and the SL3FJ are listed at O/C.com as the best two)
256M Ram - 8n
9G ata66 WD Drive
Went to play some more and first tried 115@latency 15. Worked fine, but the 3D Mark bench was almost half that at 110 (bleah) finally got the system rock stable at:
Lat-default (1 I guess)
Ram ECC off
Added another 3k rpm fan to the top of the standard heatsinc - it comes with a 6k rpm 60mm and the heatsinc is the newer 'folded' type.
With a fan on the V3 I have it running at 190Mhz as well.
The machine now boots to Win98 in under 30 sec - I'm pretty thrilled
Works great - cpu temp about 52C even after heavy gp - can spike to 54, but not much.
I call it "No-Pants Wonderday," but it turns out the police just call it "Thursday." Go figure.
my PIII is a SL3FJ
My computer is
Abit BE6(with all the sensors not working, but will send it back to fix)
CL DVD Encore 6x w/dxr3
Mitsumi 4x2x8 CD-RW
CL TNT2 Ultra
20.4GB Maxtor 5400rpm ata66 drive
and my computer is now running at 112fsb without any cooler and it's run fine
i got my PIII 550 running at 630MHz in 2.05V and without any extra cool(but i took off the 2 side covers of the case) but any way, my computer can finish 3D Mark Max's test and Sandra 99 Std.'s CPU and Multimedia (sse, mmx) testing
i'm so excited!!!
i hope my computer won't crash!
