Help with Crucial Ballistix Tracer & NF4X Infinity


Recommended Posts

ok, i recently bought 1Gb Crucial Ballistix Tracer PC4000 (2x512 dual channel kit). must say awesome looking modules. so first on first look it seems good, but when inserted on board, the nightmare began. frst left all set to auto, HTT 200, cpu:mem- 1:1... booted. gone into everest, PC2700 2.5-4-2-8 1T. okay, reboot, set manualy ti DDR400 2-2-2-5 [email protected]. no problem, pass prime for 5 hours, super pi...

then wanted to set them to rated DDR500 speed. went into bios, set

2.5-4-4-8 [email protected], all other left to auto. restarted but wont boot, just beep, beep...., so i said myself, i missed something bad. tryed again, loosed timings, rise voltage. no way man. best is welcome screen, and then BSOD. even tryed 3-5-5-10-16-24 1T, but no chance! decided to go to 2T, and miracle boot!!! everything looked ok, so ran some everest memory read&write

read- 3728

write- 1120 (dissapointing, aint?) write is just too small.

anyway to cut the story, tryed all kind of settings, and came up with DDR480 2.5-3-3-8 1T @2.9v, anything above that will result in 2T, and bad mem. write. does anyone have idea how to fix this. modules are tested on MSI K8N NEO-F, with 3000+ Venice, worked perfectly at DDR504 2.5-4-3-8 1T in dual channel mode. i'm curently on sempron 2800+ venice E6. my bios was CK8XDA19, changed to CK8XD609 (beta), but nothing!

what should i do?

maybe moded bios will help?

where to find one?

 

please help me i wouldnt like to sell this great looking modules.

When you tried DDR500 did you lower the cpu multi to make sure the cpu was stable ?

 

I also suggest searching the Stock Speed and Overclocking Database here at DFI-Street to get an idea of where to set the timings for your ram.. Auto is never the best option with a DFI mobo..

this is Sempron, multi is locked! cpu can go up to 2725MHz, have a cpu-z validation, so that is no problem, since on DDR500 sync with cpu, speed is 2000MHz.

on 2T i managed to push ram up to 307MHz (DDR614) 3-4-4-8 @ 3.0v

is it posible that board don't let 1T?

curently set to 2.5-3-4-7-11-13 2T@DDR502

did some more tweaking and get:

read 3845 (average of 3)

write 1562 (average of 3)

latency 46 ns

think those are ok?

which slots do you have them in? i have that same ram, and once i changed them to the orange slots, things got a lot better. also, i noticed that they run quite hot, and i think that was causing a lot of my problems, so, i put a fan on top of them to cool them off, they are now cool to the touch and it took my PWMIC temps down 15C. click for pic

 

i have mine running stably at 280 2.5-3-3-8. if you want i can post all my settings. the main thing is that fan, it increased my stability like ten fold. in everest i get ~7480 read, ~2500 write, and 38.6ns latency.

my board have only 3 memory slots, i'v putted them acording to manual, in first two. but max with 1T is 240MHz.

can you post your settings for me to see how you did it. may help me with something.

thanks

i thought you had a different board, so i guess you don't have the orange slots, haha :) um.., as far as your settings, some of them are prolly a little tight. try these:

 

RAS Active Time (tRAS) - 8T

Row Cycle Time (tRC) - 12T (up to 16)

Row Refresh Cycle Time (tRFC) - 14T (up to 17)

Max Async Latency - 7ns (or 8ns, up to 10)

Dynamic Idle Cycle Counter - Disabled

 

Read Preamble Time 5ns (5ns is default, but up this if still not stable, try 6ns or 7ns)

 

try those, upping the settings that can go higher if needed. or, you can start at the higher settings, and then work your way down to test for stability. here's a great tutorial for all the ram settings: http://www.dfi-street.com/forum/showpost.p...179&postcount=4

 

also, i'm running mine at 3.0v, but then again, i'm also running dual channel and at 280mhz.

priming right now, so far 40min. no errors.

thanks man, i'll try some of that settings, but for now trying to max at DDR500

anyway read&write scores now are:

read 3849

write 1575

growing!!!

your tRAS might still be a lil tight.., normally tRAS should be CAS + tRCD + 2. and tRC is good for your current settings, but as rule of thumb, tRC should be tRAS + tRP, which if you set tRAS a lil higher (2.5 + 3 + 2 = 7.5) to either 7 or 8, then tRC should be (7,8 + 3 = 10,11) 10 or 11. then, tRFC is normally best 2-4 cycles higher than tRC, so, set to 12-15. i suppose if you are currently stable, then hey, if it works it works, right? but if it fails, then start with some of these.

done! this are the best settings @ DDR500 2T, anything beyond that is no boot. did prime for almost 7 hours, no errors. see screenshot for more info.

if you're looking for the most performance, run everest and see what you come up with with those settings, save them in bios so you can reload them, and then find your best clock at 1T. once you get stable with 1T, test again with everest and compare the results. i've read that 1T and 2T are quite a difference in performance, but only numbers will tell you best which is better.
