Getting PC3200 Speed?

I'm not much of an overclocked but i got myself a stick of Corsair PC 3200.. What i do know is that to get 400mhz i would have to raise the fsb all the way to 200.. which i tried but dint work.. (keep crashing on the bios screen)..
My question is if there is anyway to get 400mhz or atleast near to it without having to go all the way to 200..
btw, my current fsb is 170 @ 10 = 1700ghz..

Hey, thats a nice piece of memory. I would unlock your chip and lower the multi, so you could increase your fsb. Actually many new boards enable you to set seperate speeds for the memory and the cpu! So you could have the memory running at say 225 fsb, while the cpu is happily running at whatever it is stable at. There are also 1/6 dividers that makes it safer to raise fsb without hurting pci cards, or corrupting your hard drive.

I really dont know much about ram overclocking, but i did unlock my cpu and managed to get 170fsb stable.. Thats probally not my max tho, meaning i will keep trying to raise the fsb..
On my mobo i noticed an option called Dram clock, is that what you talking about? if it is, the problem is that it only has 166mhz and "by spd" which i'm guessing is some kinda auto thing.. anyway, as you can see, i'm pretty lost at this, so if anyone could share me some light, i would apreaciated it..

By spd will run your ram at either 133 or 166. (it detects it from the chip.) 166 will run your ram at 166fsb.
BUT with Epox with By spd, if you exceed 133fsb with pc2100, it will run it at the FSB you specify. If you exceed 166fsb, it will run at the fsb speed you set REGARDLESS of the setting.
Examples;
By spd, pc2100, 133fsb: 133 memory
By spd, pc2700 or pc3200, 133fsb: 166 memory
By spd, pc2100, 150fsb: 150 memory
By spd, pc2700 or pc3200, 150fsb: 166 memory
By spd, pc2100, 2700, or 3200, 170fsb: 160 memory
166, pc2100, 2700, or 3200, 133fsb: 166 memory
166, pc2100, 2700, or 3200, 150fsb: 166 memory
166, pc2100, 2700, or 3200, 170fsb: 170 memory

Try your multiplier at 8.5 and your fsb at 200.
or mult. 9 and fsb at 189
or 9.5 x 179fsb
(in that order)

Well FWIW, I also got a 512 stick of the stuff about a month ago.

With my 8k3a I used the old trick where you set the cpu's FSB to 160, and the memory runs at 200. I was excited until I realized that memory running at 200 doesn't mean squat when your cpu is running at a lower bus. In other words, the bandwidth was wasted, as was evidenced in my 3d2k1 scores, Sandra mem scores, and all other benches.

So to really use that bandwidth, you'll need your cpu running at 200 MHz FSB. With my chip I can't do this. It would simply crap out on my 8k3a at any bus higher than about 180-185. On my new KX7-333r, I can run it up to about 191-192, any higher and I get horrible AGP corruption. Don't know if it's the cpu or my Radeon or what.

And as for a 1/6 divider, I'm not aware of any boards that actually have one. Please note I'm not saying they don't exist, but I haven't heard of one yet.

my xp 1600 is doing 1.8 at 10.5x170 . I am using a stick of corsiar 3200xms. When i use turbo timings i occasionally get blue screen errors (somethign about physical memory dump). Should this ram be able to do turbo timings @170 fsb? Do i need to burn in the ram?

From what I have read here there is a good possibility you will not reach 200 with a XP1900 AGOGA. That stepping is not known as a great stepping. AGOIA & AROIA are the steppings that most ppl are hitting 200+ with. I may be wrong and that chip is agood one but I would look at the cpu holding you back before I looked at memory timings

That almost looks like CPU problems not memory. If you are in doubt, bump up the memory voltage a bit and see if the blue screens disappear.
