4x 1GB Crucial Ballistix Tracer PC4000

eva2000 · Sep 6, 2005

I bought these and got them this week and one's a dual channel kit from crucial.com with L503 code and the other are 2 singles bought 2nd hand from guy at xtremesystems.org (via newegg 6 weeks ago) but the singles have different codes

Singles:

CM128M6416T27ZD2T-4YXCDFTL

vs

Dual channel kit:

BL12864L503. 16TD

Any ideas what the single stick codes mean ?

thanks

HOW IS IT?????

hehehe, come on man plug 'em in and go go go!!! multi task away...

eva2000 · Sep 6, 2005

well started memtesting the L503 dual channel pair at 10x 280mhz 3-3-3-8 at 2.76v (san diego core cpu with memtest bandwidth of 3125MB/s) been running error free for 7+ hrs before bumping to 10x285mhz 3-3-3-8 at 2.76v error free so far for 1hr (memtest bandwidth 3181MB/s)

does it have more 'pop' during regular usage?

eva2000 · Sep 6, 2005

regular usage ??? you mean out of memtest ? i always test new ram according to process outlined at http://i4memory.com/showthread.php?t=327 and right now on memtest stage

FYI, 2x 512MB Centon PC3200LL TCCD @10x290mhz 2.5-3-3-7 1T in memtest on san diego core only get 2905MB/s bandwidth!

UUghhh! I have been salivating all over my LCD screen for the last week thinking abotu 2x1gig Crucial Balisitcs. They are $400 a pop from Crucial. Cheaper from newegg if you buy the single sticks. Eva, do you know if the sticks from crucial OC better? Sierra at AMBmotherboard.com has his at 300Htt...he got his from Crucial.

eva2000 · Sep 6, 2005

hey krag

Too early to tell as it's literally been less than 24hrs since i got my crucial L503 pair and less than 3hrs since i got my singles

But the previous owner of the singles managed 285-290mhz 3-3-3-8 with them on X2 4400+ and X2 4600+.

I'm currently memtesting the L503 pair at 10x285mhz 3-3-3-8 7-17-2223 1T at 2.76v

Nice, I've got 4x512MB of those (Don't have Tracer feature though; I didn't feel like spending an extra $10 for each).
All of them had different codes and manufacturing dates. Luckily all of them worked in dual-channel simultaneously.

Also, I was able to get a really high overclock on my 3000+ Venice with air cooling (2.8GHz or 320MHz HTT stable from 1.8GHz or 200MHz HTT) using all 4 sticks at once, which isn't too common (Most can only get it on 2x512MB or whatever). Some latency is sacrificed, but at 2.5-3-3-9 it's not too bad.

This is at 240MHz; I'm using a 7:10 divider.

Tip 1: They don't respond to higher voltages very well.
Tip 2: Don't set the Trrd memory setting to 4; the Ballistix HATED that (Had to reset BIOS). It also hated it when I tried decreasing DQS Skew Control for stability (Random freezing all the time no matter what).

Mate,

Pop in all four of those modules and tell us how goes it?

Ever since Hoot piqued my intrest in Crucial's 1Gb line, I have been eagarly watching how they would perform. Now that you have 4Gb, I'm burning with curiosity here

S-N

eva2000 · Sep 6, 2005

still testing 2x1GB L503 first

memtest86+ bandwidth is pretty high for san diego core cpu!

11x 274mhz 3-3-3-8 = 3006MB/s in memtest
10x 280mhz 3-3-3-8 = 3125MB/s in memtest
10x 285mhz 3-3-3-8 = 3181MB/s in memtest

that's like equivalent to 3400-3550MB/s with a venice

krag · Sep 6, 2005

Very nice! from looking at yuor siggy...you are running the Crucial 2x1gig that has "Micron -5B D" mem IC's on the 623-3 TCCD IC bios? I guess it works' well. Thats the bios I am currently using in my DFI Nf4.

im not too sure wha tthe single stick code means, but i can tell you that they are physically older sticks then your new ones, crucial started using the .16TD sticker on all there stuff since like early june i think. and wow, great results. these sticks are really something special. no other sticks can compete with it.

eva2000 · Sep 6, 2005

yeah 623-3 bios right now - trying to stick with this for all my future memory reviews for better comparison across different modules

nice stuff

interesting that 25:30 time is only 1 second slower than 2x 512MB Centon PC3200LL TCCD @10x 290mhz 2.5-4-3-7 1T http://www.ocforums.com/showthread.php?t=410024

eva2000 · Sep 7, 2005

seems with 623-3 best i'm looking at is 280-285mhz 3-3-3-8 at 2.76v as it seems 623-3 isn't letting me loosen max async/ddram response time/preamble beyond Auto/Normal/Auto as it hangs on boot when ever preamble set at 6/6.5ns, so only 8ns/5.5ns available for me

found pcmark05 requires Trc loosened from 7 to 8 as pcmark05 loading errors at 7.

FX-57 @10x280mhz 3-3-3-8 8-18-2223 at 2.76v

Pcmark05 = 5666

Also I emailed crucial to ask about the different code in the left side white label on modules and was told the code depends on the retailer etc i.e. Crucial direct shows L503 etc, while newegg where the singles came from showed ZD2T. The orange label on modules comes from crucial/micron and the PN (crucial terms material #) denotes the memory ICs used.

Crucial confirmed both PN of 51181 use the same Micron ICs

nice piece of hardware

Looking real good so far...... I'm considering some Ballistix based on your review since you're such a trusted member when it comes to memory testing.... any chance of you playing around with 4GB at 2T just for kicks and giggles?

eva2000 · Sep 7, 2005

thanks for the praise

Will do 4x1GB later but for now...

seems Trc = 8 slightly faster than Trc 7 for this ram in superpi

These are 2x 1GB Crucial Ballistix Tracer PC4000 singles that bought 2nd hand do exactly same as my dual channel pair only diff is they actually show up as Micron instead of noname as dual channel pair does

To start with for 4GB, in DFI NF4 advance chipset bios section you need to enable PCI MMIO memory hole option to properly map 4GB otherwise you will only see 3GB of memory.

Will take ages to complete memtest LOL

More to come later
