[CoolLight]

COOL!

 

[pr497]

jeez...i feel sorry for the people who forked over a lot of money for xms3500's when they could have bought xms3000's that overclocked just as well (in your case better) for much less...
makes me feel better about buying xms3000's a couple of months back...
btw...are you gonna be posting this over at asusboards?

 

[THUGSROOK]

no, im not posting it anywhere else yet ~ its incomplete

im also doing the same testing in 3:4 mode and will be adding those results as they come in.

 

[THUGSROOK]

more results posted ~

 

[THUGSROOK]

all done

 

[Valvoline6]

pr497, lot's of people must know this too, I notice XMS3000 usually costs more than XMS3200..

[naddicott]

I'm curious what the 1:1 limits are for 2 sticks at a time with that setup... (or is that going to wait until you get a DC DDR board?) Can 2 sticks even do 2-2-2-7 timings at any DDR on that board?

 

[THUGSROOK]

on this board (p4b533) 2 sticks @ 1:1 stopped working stable at 167fsb ~
swapping sticks, adding vdimm, lame cas, didnt matter, nothing worked past 166fsb.

 

[bunnyfubbles]

The only difference is you technically aren't allowed to return a PC3000 module if it doesn't break its speced speeds, of which PC3500 offers 31.25 MHz more...

 

[THUGSROOK]

actually ~ neither stick of XMS3500 was able to run its specs on 2.6v

 

[bunnyfubbles]

so you could return it and hope for a better working sample But you wouldn't need to do that when your XMS 3000 could be rebadged as an XMS 3600

 

[Mikki]

Nice work Thugsrook, the difference between those two sticks of XMS3000 is crazy! :Q

Odd how XMS3500 stick 2 maxed out the same at both ratios...

 

[THUGSROOK]

yea Mikki ~ that XMS3500 stick#2 surprised me too :Q
i didnt think that was even possible. (same max for either ratio)

 

[Mikki]

I guess when you think about it...that's the way it should be, it should max out the same either way, as long as the voltage and timings are the same...

 

[THUGSROOK]

of course thats the way it should be
its just the 1st time ive ever actually seen it :Q

 

[Mikki]

Is this where the "in a perfect world" phrase comes in?

 

[THUGSROOK]

we have alot more requirements then that for a perfect world

but yea...

 

[Noid]

My PC3200c2 ... at 4 bank, 2.6.2.2 1T at 2.65v at 193 FSB was rock solid. (882mbs I think)

But something else wasnt...
I'm at 189.4 ...... 1:1 .... on my KX7-333.

2 x 256 in slots 2 and 3

My mem rocks ...

 

[SupermanCK]

nice...well done again thuggy

 

[pr497]

that reminds me...im running 2 x 256mb corsair xms3000 @ ddr390 (195mhz x 2) on a P4S333 (533)....but the timings arent that tight (2-3-3-6 1T) and im using a 3:5 ratio at 117FSB...i cant find out how far i can go using the 1:1 ratio because my cpu craps out at about 145 FSB (P4 1.8a)...

 

[LastRide]

The two XMS 3500 sticks would make a good pair of optimized sticks (Twin Sticks) for Granite Bay since they both perform very close to each other..Optimized by Thugsrook..LOL.

 

[mrman3k]

Very nice Thugs

theres where the lifetime warranty jumps in right?
