Help me figure out what chips are in my Ballstix

[filmbot]

Ive had these Ballstix for about three months now, and Im wondering what chips are being used in them,I have two sticks of 256.
Pretty sure Micron chips are being used but not sure, maybe BH?
If it helps any, right now I have them 2.5-2-3-5@240 2.85v and their SPD is 2-2-2-8@200 not sure of the volts.
Thank you in advance.

I would bet on Micron, 2.5-2-3-5 is typical for their chips.

Can you or do you have an idea of what model of Micron chips they are?
Or do you have an idea of how far these will go cause this is my mobos voltage limit without Booster or vMod.

Maybe 5b-C, but dunno how to identify without removing heatspreader....

I really couldn't give you a definite answer, but lower density chips from Micron like the ones used on 256MB sticks usually respond pretty well to voltage; for example OCZ 3500EB sticks use Micron 46V32M8 -5B C and respond up to 3.2-3.3V ... you should also try 3-3-2-6 timings by the way.

Crucial should ALWAYS be Micron as it is a division of Micron IIRC ;)

mine CE-5 max out at that timing on 235Htt

Most likely those are Micron's 4Y -5BD chips

Yea, Ive tried those timings but havent been able to get much higher but still stable so I figure that its mobos voltage holding me back.
Im at 240 right now, and the highest I could get was 245 and no matter the timings I couldnt get any higher 32m stable, so I just clocked back to 240 and tightened the timings as much as I could.
So you guys think if I get a Booster Ill be able to go a lot further, maybe close to 300?

incorrect. 4Y is the 4ns binned micron, 5V is 5ns, cas2 binned micron

filmbot, there's an easy way to find out:
on your sticks, there's probably a white sticker. read off the letters after the period.. should be something like .8TG
if no sticker, check your anti-static bag they came in.

like this:

or this:

also, if you're having trouble breaking 245mhz no matter what timings, either you simply have a memory controller limitation, or the sticks WILL NOT get you to 300mhz ;)

[filmbot]

Well Im on a 2.6C and its only a little over 3ghz right now and I used to run at 5:4 divider and it went up to 3.2 so I dont think its the proc.
Either way Im getting a Booster soon when I get the funds and see what happens.
Im hoping on getting very close to 300.
Here soon Im going to look at the sticks and see what the sticker says.

[ozzimark]

well, depending on which chips they are, a booster may or may not be a bad thing. chances are it's 5b G.. i've never seen C dies in ballistix before. G doesn't seem to scale awesomely with voltage, but it can take it, like 3-4mhz per .1v from my experience. if sent is right, and it's D, don't go over 3v

also, you do have a fan cooling the sticks, right? ;)

Actually I found The G chips tend to die after a few months of 2.9v

really? i've given my sticks 3.0v for about a month, done benching at 3.5v, and they're still working after a got them a year ago. keeping temps down is key

Mine died after a little more than 3 months of my Abuse

Sorry to bring this thread back to life, but my static bag says ".8TG"
So does that mean that they are 5b-G?
And if so, now I have them on a DFI Ultra and will the extra volts be needed to go to maybe 250?

Dude the only way to tell is just look at the chips.. it is so much easier than trying to guess..Do us all a favor and just remove the heat spreaders and look;)

[filmbot]

Ugh, alright.
Whats the best way to get them off, I cant really figure it out and when I get them off, can I put them back on?

[nn_step]

This might help taking them off http://xtremesystems.org/forums/showthread.php?p=700673
and you can always put them back on...
