Corsair XMS 3200 and Higher FBS.. HOW?

I have a A7V333 rev 1.4.
Bios 1014
Tbred XP2400 (AUICB week 44)

I cannot get past 141 in Turbo mode with 2,2,2,5,1T. (at 15x Mult.)

I cannot get past 166 (with a 13x mult.) without setting my memory to 2,3,3,6. My memory benchies in Sanrda are about on par with PC2700 Cas 2.5 at this!

How in the world are you guys getting 180-200 front bus speeds and maintaining the fast memory settings and getting 2800+ in memory benchmark in Sandra?

Is it that my CPU cant go past 2.17ghz?

Would I be able to reach higher front bus speeds with faster memory timings IF i unlocked my CPU?

I dont want to unlock it and then not be able to get back to having the higher multipliers.

I wonder if I unlocked it I could get 11.5 x 187 with fast memory timings?

Tell me what memory timings you have with 180+ front bus...

Maybe i'm crazy here, but isn't the A7V333 motherboard limited to a 333Mhz FSB? (I can't double check since i'm at work)

If that's the case, then right there is probably what is limiting you.

I would think first off you would need to unlock this baby so you have the lower multi., then I would lower that multi. down to something around 9 or 10 and start from there. I think your trying to push the chip alittle hard and reaching the max of its abilities. I think you need to connect the 5th L3 bridge to get lower mult. below 12.5.

I may unlock it, but I still need to know how what memory timings are any of you getting that have higher front bus speeds (IE over 185mhz)?

I set my DDR400@DD333 by spd (PC3200 cas2.0@PC2700 cas2.5

ok ill break down and tell ta my ancient secrets!
on the timings disable the t1.for somereason it really limits the fsb you can run with best timeings.2.0-2-2-5 t2 should take you upto and over 200 fsb

yes unlock that chip.if you dont u wasted the money on the corsair memory.
also check out the asus mobo section and do a search on "vdimm overvolt" lets u increase the voltages on the memory also.i had to but u might not need to.


i suggest while doing the memory ocing ,drop the multi so the chip doesnt run over the stock speed.that way you eliminate cpu errors.then once u maxed the ram out put that max fsb with a matching multi to take back to cpu max mhz.

once u get a hang of that mobo its like driving a caddy

btw Beast_USA if u change the dram timings to "user defined" instead of spd u can change the timings.

My XMS3200 is running at 2-2-5 1T C2 199MHz @ 2.8vdimm. The way I did it was to lower my multiplier and jack the FSB. XMS3200 is rated to do 200MHz 3-3-6 1T C2/C2.5 (depends on what stick you got). Hope that helps somewhat.

Thanks, I know just runs better for me when I don't go there. LOL

Turbo all the way here. 2-2-5-2-1t with 4-way interleave @ 205 and alitlle bandwidth for ya.

hi,

just unlock it with grease, if you don't want it unlock wipe grease off and youre set,

highspeedpc has a nice kit for cheap
