Bought one pair from crucial.com and i got a 2nd set of individual single 1GB ballistix tracers 2nd hand to make up to a 4GB config

Singles:

CM128M6416T27ZD2T-4YXCDFTL



vs

Dual channel kit:

BL12864L503. 16TD



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

Now both sets do exactly same settings 280-285mhz 3-3-3-8 8-18-2223 1T at 2.76v. So thought I'd try 4x 1GB config with 2T.

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.

from 623-3 official bios

VID = AUTO
VID Special = AUTO
chipset = 1.6v
LDT = 1.3v
LDT 3x
Vdimm = 2.7v (2.76v real) +0.03v = enabled = 2.79v vdimm

Will take ages to complete memtest

edit: more piccies

@12x250mhz 3-3-3-8 2T at 2.79v test #8 will freeze at 19%


don't have enough patience to figure out the test #8 freezes so dropped down to 240mhz 3-3-3-8 2T at 2.79v with no probs

- fixed freezes by swapping dimm slots for ram see http://i4memory.com/f50/4x-1gb-crucial-ballistix-tracer-pc4000-dfi-nf4-ut-sli-dr-1316-post19639/#post19639













hmmm Pcmark04 only sees 3GB of ram heh

Pcmark04 = 5,582

looks like you will have that machine busy for a while eva
Looks good tho, it will be interesting to see how far 4 gig can overclock

eva2000

Yeah will be a while to complete - right now first standard test pass upto test #5 and took 22mins 26s to get to that point

groovetek

how much do these cost over here? can you even buy them here???

NiSMo

Nah u can't get them here just yet....

hopefully soon though click me

eva, the_rick and i think random_ninja all got there's from www.crucial.com and it set them back like $650-$700 after customs duty

eva2000

Butters and I were over charged for customs by UPS http://i4memory.com/f50/2x1gb-kit-get-1213-post19526/#post19526 not sure about random_ninja though.

crucial ones cost me AUD$585 + AUD$123 overcharged customs should of been AUD$89

2nd hand ones cost me AUD$440

so average cost per 2GB set = AUD$557 if customs was charged correctly or AUD$574/each with incorrectly charged customs heh

Newegg.com has 2x1GB sets for US$310 now so if you can get a friend to send you some via USPS EMS probably cost AUD$520 after 10% GST - but i think they're out of stock right now due 9/9.

the _rick

hey, i wish, none here.

Updated first post with standard test run - 1 pass + upto test #4 2nd pass took 1hr 36+ mins

Decided to go higher to make memtesting go faster at 12x 250mhz 3-3-3-8 2T 8-18-2223 at 2.79v so far memtesting fine
