Can ya go higher. Although for an older generation of boards, my board is hitting 171fsb rock stable w/ CAS2 timings.
 
i have a one stick on samsung pc2100

I was going to put a stick of ocz pc2700 ut i dont know now

182FSB is possible with bios flash....

I need to unlock my chip and get a better psu - my antec 400watt is dying on the -5V rail
 
That's a sweet FSB in the Asus mobo there! My A7V266-E doesn't come near that, but the Epox,,, that's a whole nother story :)

You can open the PSU and there are two pots that let you adjust the 12V and 5V lines. Atleast on my 400W antec there is.

What model do you have?

Mine is the PP412X or something similar.

i have the 412x as well.... it needs help!
 
um i got a prob with mine, i tried overclocking mine, it was unreliable at 136mhz, thought it was bad dividers, so i then pushed it to 150mhz, thing didnt detect my ram! and i have 2sticks of 256mb PC2700 OCZ!!!! now its stuck in jumper only mode and every time i change it to jumperfree, it give the no ram beep over and over again. And my retail Xp1800 is an AGOGA with stock vcore at 1.81, i havent even dared to touch voltages yet, bc vcore was already set high. how do get back into jumperfree?!?!? the DDR333 ram works fine at 133mhz though.

would removing the battery and putting it back in do anything to fix my problem?

all that does is reset your cmos - maybe you got something set funny - so at worse it is worth a shot.....
 
Clearing the CMOS should get you out of the loop- it's probably still holding the 150mhz setting, and your system may not run at that speed with the OCZ ram - especially if it's set for an aggressive memory timing. I just sent back a stick of OCZ PC3000 (early revision) that wouldn't run beyond 133 with 2T-Turbo (2-2-2) settings in our A7n-266-C, and had to be set at 2.5-3-3 (2.5 Normal) to make it to 140, but couldn't get beyond that reliably. We're now running Samsung PC2700 @ 146-148 mhz fsb w/2-2-2 timing (this is the cpu ceiling for our locked processor- a 2001 model 1600+) and it's rock solid and happy....
On our board, shifting the cpu voltage jumpers from automatic to the highest setting (listed @ 1.85- reports @ 1.9) also clears the CMOS settings..

Best wishes...

worked, im now floatin at 143mhz at locked proc multis.. would a locked xp limit fsb more so than a unlocked xp?

yes becuase i am capped at 143fsb
 
"worked, im now floatin at 143mhz at locked proc multis.."

Congrats :)

would a locked xp limit fsb more so than a unlocked xp?

Well.. yah, sure, you betcha... unless you left your multiplier at the stock setting after unlocking it... which kinda defeats the whole point of unlocking. Most processors will overclock anywhere from 10 to 30% over their factory rating- within that limitation, the more fsb speed you can crank out of it and still keep everything happy, the faster your system will be... Back in the good old days, of say, the A7V Classic, the board wouldn't take a whole lot of fsb tweaking, so to wring everything out of a processor, you unlocked it and cranked the multiplier UP-
Today, some of the newer processors won't handle a tremendous amount of overclocking, but many of the boards will eat up gobs of fsb, so the ticket is to crank the fsb up and the multiplier DOWN, to keep within the cpu's operating limits-
If your 1800+ is happy at 1645mhz (11.5 X 143), then it will be happy at 10 X 166 also, and your system would be considerably faster- Providing that everything else is ok with it (ram,video card, etc..).
Your 143 ceiling could be a limitation of your ram, or you may be reaching the edge of your cpu's limits. People have had notoriously inconsistent results with OCZ, but it seems to usually perform fairly well IF the timing is kept relaxed- tests I've read on it bore this out as well. If you set your ram timing to autoprogram by SPD and then run Sisoft Sandra, it will probably show that it's EEPROM'ed for 2.5-3-3 .. with those settings it may work well for you if you decide to unlock..

Apologies if you know all this already....:rolleyes:

Best wishes.. :cool:
 
i didnt know that ocz was questionable, but i didnt know to multiply down and crank fsb high, seems i gotta unlock. thanks for me telling me this, it confirms my tbirds condition of 10.5 at 150ish something.
