OCZ DDR Booster won't work properly

[Supertim0r]

Hi

I've got a booster + 1gig VX
worked great first time but it wont stay @ 3.4/3.5v after a cold boot :confused:

it worked @ 3.5v during 25h (burn-in) and now i need to clear the cmos and wait like 20-30min before upping the voltage (im stuck @ 2.7-2.9v)

someone got the same problem ??? :(

another question...when its 3.4V on the booster...is it really 3.4V or something like 3.25-3.3 ?

[EnJoY]

Sometimes the booster is too sensitive to case vibrations and this can cause visible fluctuations in the voltage...most likely from the vibration of the adjustment knob. The booster is just plain annoying overall in my opinion.

I hope you had some fans cooling down your Booster and RAM at that voltage. I fried my first Booster due to my failure to provide an active cooling solution for the unit.

got a panaflo 80mm + 120mm papst
they are not over the memory but perpendicular
they arent hot (mem / booster)

thanks...i appreciate your help :toast:

booster not hot = not working with 3V+, I always have to touch the PCB to make sure it's working properly.

Calibrate it, then you will know.

[Supertim0r]

finally work
250fsb 2-2-2 @ 3.5v (3.5v on the booster...really 3.5v effective ?)
ive tried 260 @ 3.5v = 2300errors / 1pass
@ 3.6v = 76errors / 1pass

im tempted to push 3.7v !!! (sure this will give me like an effective 3.5-3.6v?)

3.7 should give you 3.7.... if you calibrate it.

calibrate ?
what do you mean ? :stick:

turn the small dial so the LED display shows the same as what your multimeter does.

doooohhh
ill need a multimeter ;)

This is off topic, but nice sig Supertimor. That's sweet. It's that way at LAN parties.

[Supertim0r]

damn...need to RMA my pos Booster :cussing:
im so UNLUCKY with hardware :(

[Stealth5325]

I've noticed that the booster drops voltage under load. Even with a ton of cooling, if you set it to like 3.4v in the BIOS, during memtest and superpi and stuff, you'll get like 3.25v. You have to set it like .15v higher than you want to get the voltage you intended to under load. Of course, this means you'll get .15v higher than you want at idle...

i think my pot is dead... maybe ill try the booster modification

That seems to be a high-failure part. My booster quit on me and I was about to RMA (had a number assigned) and saw Bigtoe mention as much around here. Said people didn't keep the pot cool enough so it fried. Whatever, 60 - 70 cfms of 19 - 20 C air on mine and it toasted. Replaced it with a multi-turn cermet myself since I didn't want another high-failure part in there and couldn't be happier with it. (The tuning that is, not so much the booster ;) , not even in use atm) If you do use a meter to monitor, you will definately get much more precision in tuning the thing then with the single-turn original pot.

should i try replacing the pot or not ?
i know its the pot...when i force it..its sometimes show 3.2-3.6v instead of 2.6V :rolleyes:

I liked how it worked out for me. It's your call though because you know once you do that any warrenty support is gone. Not too tough a call for only a fifty dollar item, but still something to consider.

mod done
my uncle did the mod for me...
what can i say...WOW what an improvement
this is SO MUCH MORE STABLE
he added a 10k trim pot 25turn (40$ value)
ill post pics tomorow !!!

can you elaborate on this for me? i just got one of these and would lke to calibrate mine before using it...

thx perc,

put your DMM probe against a reliable point to measure voltage with, and turn the small dial that changes what is shown on the LED display so it matches what your DMM says?
