overclock amd 64 2800+

[Brotakul]

AMD Athlon 64 2800+ @ 290x9 @ 1.6v
Arctic Cooling Freezer 64 [41grd celsius max in full load]
EPoX 8KDA3i, sk 754
512 DDR400 Kingmax [186Mhz] 2.5.3.3.7 default timmings
PSU Allied 400w true power
FSB=290
multi=9
HTT=2x
ram divider=133
CPU clock=2610

this settings are stable [prime95 for ~2hours, memtest for ~1h]
i want to break 300 for the FSB with 1.65v, but i guess my rams are not helping me. i tried the 100 divider but i cannot boot. i am very close to 2700Mhz and i really want to make it possible. for FSB=300 with the ram divider to 133, the real ram frequency is 192Mhz. i tried 2.5.4.4.8 timmings with no results. it seems that my rams don't support CL3 because with FSB=290 and timmings at 3.4.4.8, the system doesn't boot.
do i have any chance to get 2700Mhz with this components? thanks
ps: excuse my english, i'm foreign

So, does it not boot when you up the voltage? Have you tried smaller increments with the voltage? Or does the mobo only allow .5 increments? I would try inching up to 1.65, but slowly. I mean, you aren't that far from stock voltage, 1.5V...Can you loosen the timings any more, I mean without sacrificing major performance loss? This might be the max stable, I mean that chip was marketed at 1.8Ghz...

Thanks!

i tried the 1.7v. the increments are 0.05v. i tried 2.5-4-4-8, 3-3-3-7 and 3-4-4-8 timmings with no succes. i succesfuly boot at 300x9 but after i see the desktop i get the bloe screen of death . should i try 1.75v too? isn't it a little too far for sk754? the mobo [EPOX 8kda3i] seems to react well to OC, but can it be from the mobo too?
i still think that's the ram witch keeps me down to 290x9. the ram is 512 DDR400 Kingmax MPXC22D-38KT3R-FNA PC 3200. do you know something about them?

 

[ikjadoon]

Yeah, 1.75 is pushing it...Have you tried using 2T on the memory?

[Brotakul]

i only use 2T. i can't use 1T, not even with default timmings and frequency.

Ah...Hmm...That is a pickle, then...You could try getting some 3500 RAM to try out and see if it is the RAM, but that might be hard to do, provided it is sometimes hard to return an overclocked part, What I don't get is why the computer won't boot with the memory divider...I mean, the RAM currently is actually underclocked...I would have to say that it is the max for the CPU because that is actually a pretty good heatsink/fan...I'm sorry!

so this is the highest stable freq? from 1800Mhz to 2610Mhz...that's a preety good OC but i tought since amd 64 2800+ is the "junior" of amd athlon 64 series, it should be the most OC'ble on it's kind since he's using a multi=9 instead of 10 like "3000 and up" processors. anyway, +810Mhz it's good as it is and 2700Mhz won't help me on increasing the performance. i just wanted to get the best from it, just for the OC enthusiasm

thank you for the help. i guess i'll stop here with my OC.

 

[ikjadoon]

I guess it would be, then...All right, good luck with it! It already is a BEAST!
