Got some GSkill 4800 on there, and can't get it to boot into Windoze at 215MHz x 10 even with 3.1V, though it will happily run the tightest timings 2,2,2,5 at 210MHz with 2.9V?

try DRAM Bank Interleave - Disabled

for some reason ive been having the same problem as you with my GSkill LE, but, setting DRAM Bank Interleave to Disabled has got it booting & stable at high htt using 2.8v.

not an ideal fix i know, but better than the endless shiznet i was struggling with earlier.

I too have 1gb of gskill la and a week 50 winchester 3200+. I was able to run the ram happily at just under 320 mhz at reasonable timings (2.5,3,3,7) with the processor at 2720 mhz until it spazzed out mid game (I think I was running the cpu voltage too low). The gskill la is optimised for high fsb speeds (275-360+) at reasonable timings rather than ultra tight timings, although I have read about people running at arround 230mhz at 2225. 3.1v seems a little much, 2.9v should be more than adequette for this ram. I would reccomend trying the ram at high fsb and reasonable timings, rather than tight timings.

OneWingedAngel, would you be able to show the voltages/timings you are using with that setup, so I have a guide? I have tried looser timings, but they don't seem to increase the stability. Even at SPD settings (2.5,4,4,8) this RAM is not Prime (Blend Torture Test) stable at anything over 210 MHz at the moment. Though I haven't tried 2.5,3,3,7 yet. Will give that a go next. I don't want to give up on the GSkill LA until I've covered all the bases, but I do have RAM alternatives. I've only got the one A64 CPU, so if that's crap I'm stuffed for now.

VoG, I've just tried Bank Interleave Disable, and that doesn't seem to have changed things either?
 
i had trouble with running high fsb's with my gskill LE until i filled the 12v molex onboard, now i can run 305fsb x3htt 2-4-7-3 timings. using default voltages. but cant overclock the cpu very high only 2440. even without running that high a fsb it wont go much over that with any voltage.

(edit:- i also flashed the bios to the beta 209 one. loaded optimized defaults, turned the computer off and unplugged the power cord, waited a few seconds plugged it back in, so i dont know if that influenced the stabilty???? )

im sure its my psu though, im using a globalwin saf 520w psu, i had problems with the 12v line dropping low on my abit nf7-s when overclocking,
and plus its only a 20pin psu. i even have a adapter cable 20pin to 24pin and it just made the system more unstable.


anyone know y my pwmic temp is 10C above every other temperature?
where abouts is it? anyone know? need some info on it, mine went upto 62C when i put more volts through the cpu and ran it at 100% load.

it didn't for me until i started setting my own ram timings as well.

bank interleave disabled
2.8v
cas - 2.5
ras to cas - 3
ras precharge - 3
cycletime - 7
bank cycle time - 10
dram idle timer - 15

this is on GSkill LE & it's now stable at 275 & i'm still playing around looking for the rams limits. before i disabled bank interleave 215 was the limit & not a smidge more with out major instability & multi restarts when ever i changed something in bios. for some reason it just seems to have settled down.

Understood. What voltages are you using for CPU VID, LDT bus, Chipset? I'm currently using 1.45, 1.3, 1.6, 2.9 (RAM).

well to reach my max stable 1 : 1 clock i used.

LDT 1.20V
CHIPSET 1.50V
DRAM 2.9V
CPU VID 1.5V
CPU VID special 123%

but i'm watercooled so i don't recommend that level of cpu voltage if your aircooled.

my rams maxed out at 295 1:1 1T command, disabling bank interleave is hitting my super pi times by about a second, but if i enable bank interleave i get instant crashes, & the bios won't save any changes with out restarting 2 or 3 times.

any way click me for max stable 1:1 of 295 x 10 - 1T

gonna try using dividers tomorrow, just to see how high i can get.
 
TCCD realy is depending upon the week.

437 is king of the low voltage stuff, 440 onwards was responding to higher Vdimm to help keep tighter timings.
 
try running the GSKILL LA in 2T if you have problems, remember it is ram rated for pc4800 at 2T.

Try using the 9/10 divider.

I've managed to get my FSB to 270MHz, multiplier is at 10, HTT is at 4x.

I've got my CPU on 1.57V, RAM at 3V and I think I've got the LDT and NB at default settings.

No matter what I do though, I can't get it to post on anything over 274MHz. So I'm pretty sure this OCZ RAM is holding me back.

EDIT:

I've got my timings at 2.5-3-8-3 1T with DRAM Bank Interleave enabled.
 
hi guy's what ram settings would you recommend for a gig of crucial pc3200
to get it to run stable at stock.
As im having problems like prime95 is still running test one after about an hour. memtest is fine after about 2 hours.

my cpu is a 3500 winnie

thanks

437 is what I have, and I haven't noticed any improvement in stability with extra voltage so that makes sense. 2.9V seemed to give marginally more stability at 2,2,2,5 timings. It actually got less stable with slacker timings???

I've put the Corsair XMS4400 TwinX in now to see how that fares. It's the Blend test on Prime 95 that keeps failing though. The other ones trundle along happily until stopped.
 
its does seem a little bit of a lotto with some TCCD on NF4's, but be something to do with the packaging/layout.
If ppl are having problems with corsair ram, pls give as much info from their label as possible

Have you tried the ITE Smart Gaurdian Software?

Nah already sorted my monitoring - turns out board doesnt like one of the diodes being monitored but got it sorted!

Now I know my CPU/Chipset/PWM temps with my fav app!
 
Is there a way to enable ports from the front of the pc? My front ports on my centurion 5 dont seem to work both the usb and audio ports seems not to work

Depends. Look at the manual to find out if you have any audio connectors or any USB ports on the mobo to connect your case's front ports to - think it varies from model to model as to the extras.
 
Mine are working fine, and did'nt need to have the extra ports enabled in BIOS, but always worth checking.
Otherwise you have them plugged in wrong
