How high can you run pc3200?

itizme · Nov 16, 2003

I have mine set at a fsb to dram ratio of 1:1 and the fsb@225 hence my ram is running 225x2=450 with auto voltage selected and settings of 3,4,4,8
is this correct that I am at 450 now? (I know the 225 and ratios are correct)

what do I need to do to keep this ram stable when I go to 250 fsb with the same ratio of 1:1

No, some new corsair is not the answer
if there are reasons to change the settings please explain why, I am not exactly a noob at overclocking but it has been a year since I have needed to overclock (my last system)

btw my ram is 2x512 dual channel mode

That fsb is impressive w/pc3200 1:1. What brand? model?

2.5 V 8K REFRESH 3,3,3

are my timings wrong the way they are??
they are 3,4,4,8

itizme · Nov 16, 2003

update, I tried 3,3,3,8 and couldn't bench

Grandpa Dan · Nov 16, 2003

They seem a little lax but they would need to be at that speed. Ram is picky it doesn't like to oc very much. W/ mushkin pc3200 the best I've hit was 208 1:1, 2-2-2-5 @ 2.85v.

BTW that link doesn't work.
Are you running memtest86? 1 pass is all that's usually needed to find ram probs.

itizme u should be extremely happy with those results 1:1 on pc3200....your not gona get higher than that most likely.

jus switch to 5:4 and watch your **** skyrocket.

itizme · Nov 16, 2003

What would be better, the speed or the settings
ie 225 on dram or the 3338 instead of 3448?

Grandpa Dan · Nov 16, 2003

Run your fsb to 250 set your mem @ 5:4, that =ddr400. run memtest 1 pass. if clean, start tweaking your timings. 2-2-2-5 = most agressive, 3-4-4-8 = slowest.

batboy · Nov 16, 2003

Yep, what gramps says. Sometimes the 5:4 ratio with tight timings comes close to beating 1:1 with relaxed timings if the 5:4 will give you a higher O/C. Benchmark it both ways and see. The only thing left to do with your timings already relaxed is to max out the vmem.

Thanks guys, going to do some testing
Just another reason why overclockers.com rules!!

Hmm, I found probs after 7 passes.

- burn
- run

Twister1234 · Nov 17, 2003

Ven0m · Nov 17, 2003

they are 3,4,4,8

can those be 4.3ns chips? if so, 225(450DDR) isn't surprising, they should hit 232(464DDR), then more than that would be overclocking

have you tried more than 2.5v yet?

Twister1234 · Nov 17, 2003

malon,that sounds good,i´l try it...^^

Corsair PC3200 C2 (BH-6) running 220 2-2-2-x 2.9v
