12v rail Question

[khurios2000]

Got TTGI 550SS last week,
boot it up and run prime95, the 12v rail dropped to 11.50, even 11.30 after 2 hours priming.

Does this number still reasonable?

ps: also the 12v ran at 11.90v idle
all voltage measured using radioshack digi-multitester

11.34vdefault stock vcore priming95

11.4 is the lowest it can go, before exceeding ATX specs. So 11.3 = *very* bad.

 

[khurios2000]

anybody know the voltage tolerance/span for 12v?
kensai, yes its 11.30v now

Hmm, if thats what it's reading with a volt meter, then thats definatly too low, you will likely start running in to problems.

yep, +/- 5 % is the standard. most good ones spec +/-3% well most quality ones can easily hold +/- 1% or better

OP - If your readings are from software and your system is stable, ignore it and get yourself a meter (can get a basic DMM (digital multimeter) for $10. or less) if you really want to know. The HW monitor sw is notoriously inaccurate.

actually i did measure the rails using radioshack multimeter,
what shows at asus probe seem to be correct.

i dunno anything about that psu but maby adjusting the pots to get higher voltage if it has it.

it has knob for ajustuing the fan speed, i dont find any knob for volatge adjustment

My TTGI does the same thing, although I haven't had any instability issues due to the fluctuations.

Does your TTGI diving deep like mine?
12v = 11.34v?

Some PSUs have voltage adjustment pots inside but often you will void the warranty if you go inside the case. IAC, since it measures with a meter to be out of tolerance, you have grounds for RMA.

Yes, it does.
