Wanted to share: Dual PSU Action

JrRacinFan · Jun 15, 2008, 04:47 PM

While testing to find stable clocks with my motherboard I decided to connected a dedicated power supply for graphics. I found out the easy way that all my instabilities are not caused by power consumption.

I know this is not a pretty site with wires but the power supply stays cool and does not even get remotely warm. Any comments/suggestions are welcome.

Main question being to my post though is this, Leave it or remove it?

intel igent · Jun 15, 2008, 04:49 PM

any improvement's at all?

JrRacinFan · Jun 15, 2008, 04:50 PM

None really intel. All I have noticed is that i can push CL4 up to my max fsb.

Cold Storm · Jun 15, 2008, 04:51 PM

Bro, I think its crazy that you have that you did it! But, it works! Just have to see if its "safe"!

JrRacinFan · Jun 15, 2008, 04:52 PM

Perfectly safe man. I've been running with this all this morning. I will leave it in for a few days and see how well it does.

at max FSB without the added PSU what are you at CL5?

i dunno if all you get is 1 bump in CL timing and everything else is equal....

any improvement on the GFX side?

have you run any benches?

JrRacinFan · Jun 15, 2008, 04:55 PM

Been running benches all morning. Only improvement is the jump to CL4.

intel igent · Jun 15, 2008, 04:59 PM

no increase in FSb of GFX clock's?

have you tried to put only the MOBO on main PSU and GFX/peripheral's on the second?

what does the CL4 give you? anything noticeable?

JrRacinFan · Jun 15, 2008, 04:59 PM

No increase in vid card clocks ..

I can try the hdd's/optical if you want and post back.

CL4 drops about a second off my superpi

intel igent · Jun 15, 2008, 05:09 PM

it's not for me your trying, it's for you

i'm just making suggestion's

Cold Storm · Jun 15, 2008, 05:14 PM

I think doing that would be a great idea. Puts less onto the computer.

JrRacinFan · Jun 15, 2008, 05:23 PM

After doing what was suggested. This the good reason to push for a good psu.

And I have a little bit of room to go.

intel igent · Jun 15, 2008, 05:25 PM

what were your #'s prior to this?

edit : you were at 2.5 before? not bad an extra 400mhz!

panchoman · Jun 15, 2008, 05:35 PM

jr, if you're not getting anything outta the dual psus, you're better off sticking with 1 psu. i imagine you'll be on a worse part of the efficency curve and its just much more of a hassle really..

JrRacinFan · Jun 15, 2008, 05:38 PM

Yup working on it pancho. Lookin at some new motherboards. Once I get that I will resurrect the dual psu project. I just noticed thats its more stable and mroe responsive.

@intel

Thats my max stable right there at CL4.

intel igent · Jun 15, 2008, 05:42 PM

so you gained 400Mhz and bumped up to CL4?

if so

JrRacinFan · Jun 15, 2008, 05:51 PM

Disconnecting the slave psu for now until I get a new motherboard. It gives me no true noticeable improvements due to the 975x chipset. If I had a P35/X38/P45, then this would be a different story. Not much more to see here.

Cold Storm · Jun 15, 2008, 05:52 PM

Well, at lease it shows you what is needed. You've tried all there is to try before getting a new board.

Xazax · Jun 15, 2008, 07:35 PM

Personally, i would get one of those "dedicated" PSU's for the Graphics card ive seen a few, that might help more having your dual PSU's :P

But yea your crazy...

farlex85 · Jun 15, 2008, 07:39 PM

Seems to me this would only be useful if you vmod the graphics card, or if you have water on the proc and thus are able to push large amounts of power through it. W/ an unmodded card and air cooling, there doesn't seem to be much reason for it imo.

JrRacinFan · Jun 15, 2008, 07:41 PM

Thanks for the input farlex. Like I was saying, I just needed to test and make my instabilties werent due to an underpowering psu. Thank you all for your opinions.

Ah yes ok I see. Yeah that does seem like a good way to test for that. I'll keep that in mind if I ever run into a similar situation.

Xazax · Jun 15, 2008, 07:43 PM

BTW what are you watts and amps on those PSU's?

JrRacinFan · Jun 15, 2008, 08:10 PM

The Antec 500W: dual 12v 18a. The @Power 550W: single nominal 24a/max 28A.

@farlex

Just figured since it wasn't an underpowering psu might have wanted to play around and bench a little. Didn't work out as well as I wanted.

dark2099 · Jun 15, 2008, 08:18 PM

Possibly with a better board that will be helpful, I'll definitely keep a close eye and maybe fiddle with that some time.
