Tips for 8k3a+ / Unlocked 2200 / Mushkin pc300

[oc jason]

Well my system consists of a New 2200+ Unlocked, a Epox 8k3a+ and a stick of Mushkin pc3000 that spans well over 200fsb, 221 to be exact but that is at 6x and slowest settings.

With my previous Unlocked 1900+ i can rn 183FSb cas 2 all turbo settings on this memory and a multiplier of 9.5x giving me 1740 mhz overall.

I have not installed this 2200 yet, as i am waiting on better cooling than my Alpha PAL 8045 will provide. But i know that Mushkin pc3000 can run faster then 183 cas2 all turbo and be stable. But for me it didnt..... I have been running this mem at 183fsb 2.7vdimm for 3 months, do I possiblly need to burn it in more at 3.2vimm and SiSandra Bench over night a few times? Or am I missing some wpcrsert/wpcredit settings that allow for better memory performance.

I have tried ram in slot 1 and slot 2, also have tried all BIOS but 2619 was most stable at highest FSB. Any amount of vdimm over 2.7 didnt seem to make a diff as Mushkin does not like high vdimm. I also have manually set to turbo timings insted of just selecting turbo.

In my previouse system my 8kha (kt266) was running at 165 fsb...the limit of the board. That made my AGP/PCI bus 82/41 and all my components were perfect

Now that i have a 1/5 divider, a 205 FSb setting gets me the same 82/41 AGP=PCI bus speeds, so i KNOW FOR A FACT my vid/nic/hdd will be just fine at those speeds. But it just will NOT run at those Bus speeds anymore.

Can i just get some over ideas on what else i might try, or you think id be better off with a KX7, ot the Abit IT7..I thought epox was best for overclockign.

I can run my 8k3a w/ no prollems up to about 220FSB or higher w/ relaxed memory timings :)

only real prollem at those FSB's is the agp tearing....makes 3dmark a no-no :(

[oc jason]

I have no problem running relaxed settings since it is only a very small difference in overall performance if you can make up for it in FSB. I got the highest 3dmark score with normal timings and 193 FSB. That is just it, it can run 205 at 6x giving me just over 1200mhz, when chip (xp1900+) is capable of 1740 overall is where it hit its max. But at 7x it will not do 205 at most relaxed timings. That is still WELL under the chips max mhz.

I am just trying to run Normal Settings Cas2, bout 200-205 FSB. And am wondering why it wont do it at any X but 6. Id love 10x200-205 on this 2200+

I am pretty skilled in overclocking, but this is just stumping me.

Hmmm obviously you have tried upping the voltages. I dunno. Ya got me. I have my xms3000 with bios 23.12 at 191. This is at most agressive timings and with 3.0v. Maybe a bad stick of ram? Burn in more? :confused:

[oc jason]

ya i think it needs burning in, and a 2312 BIOS. I have never used those BIOS and i seem to see alot or users do very well with it.

As far as burning in? I set it at 2.5vdimm and see how high it will go at 2.5? and whatever speed that is, i then up the vdimm to liek 3.0-3.2 and let it burn in SiSandra over a few nights to get it all broke in?

U think removing the Heatspreader and useing some AS3 between Chips and Spreader will help cooling at all if i need to use 3.2 for burn in

[Chong345]

The 23.12 will be MUCH faster than the other bios'. You won't get as high fsb's but you'll score better than those high fsbs. Anyway as for burning in I'm not sure cause I didn't have to burn in this ram.

[oc jason]

thanks, ill flash to those, and install the 2200+ burn in ram and see what i get

thanks alot for our help

[Chong345]

nice avatar. Also for reference the 23.12 at 185 was as fast as 25.08 at 199 at same timings. Its like this for all the bios' after 23.12. It rocks. I haven't been able to top it in 3dmarks with any other bios.

Man dont get any artic silver 3 anywhere near those ram traces or it will be toast. For anything dealing with ram I use Artic Alumina because it is easy for any artic silver to screw you over hard when using it around ram. I reserve the use of artic silver for the gpu and cpu only.

Don't push the mem voltage too high.... Often it will cause instability. My corsair doesn't like 3.2v, but it does like 3.1v. Just gotta find the sweet spot.

yep! thats it.

btw.. in my last 8k3a+ i was able to bench @217 (cl2.0-3-3)without agp tearing.. but she is dead..hehe
my new will arive tomorow.. lets see ;P
