OK, here goes.

Hello everyone! Due to lack of things to do yesterday, I decided to push my PC a little further so I introduced my Toledo to Sir 2500MHz and also witnessed a joyful reunion with Mr. Perfect 1000MHz HT.

I also figured that since the Sapphire x1950 GTs are basically x1950 Pros, just randomly picked and lowered clocks, why not run mine at Pro speeds?

So, with that done it was time for stability testing. OK. No crash.

Time for benchmarks. Let's try 3DMark06! Yay, improvements! 5401 marks, not much but hey, it beats my previous 5000-ish.

Although... I got some really odd colours during the Canyon Flight test, with the screen even going all white a few times.
My first theory was that my card needed more power than my PSU could give it, so I did alot of reading and thinking. Anyway, long story short, turns out it was just an ATI TrayTools option that was the cause.

This got me thinking though... Maybe I should get a new PSU anyway? I know my current one is supposed to be kinda weak even though the voltages are good and stable.

Do you think I need a new one? I've never had any issues and I have never felt that it is hot on the outside, just warm.

Oh, and here are everest's cache and memory benchmarks. Won't beat JEmmaB, heh, but what say you others? Any good?

Oh! I almost forgot! I bought a sound card today, SB XtremeMusic for ~$24. You Americans got all your special offers and shopping sprees and all that, I didn't wanna feel left out.

Wow, HothBase, according to most sources I've looked at, your PSU is horribly inadequate for your system.

I used to run an X1950XT, and though this card is a couple of steps up than the X1950GT you run, it's still basically the same GPU (the R580, unless I'm mistaken, of course). This source says that a card with an R580 requires a massive 38A from the 12V rail. Another source quotes a slightly lower figure of 30A from the 12V rail.

Nevertheless, the point remains the same.

12A from the 12V rail servicing the needs of the entire system is woefully inadequate, I'm afraid to say.

Hope this helps.

Thanks for the info joe! Actually both sources say 30A for a single card. Heh, only 18A to go

I have actually been looking at a couple of Corsair's power supplies for a while and noticed that they all have a single 12V rail. What's the advantages/disadvantages of having single/multiple rails?

Ya think this CMPSU-400CX would suffice or should I get an CMPSU-450VX or one of the even higher wattage ones like 550W?
I probably won't upgrade my 939 much after this, I have no intentions of going multi-GPU or anything like that. Most likely I'll just get a new AMD rig when the time comes.

Long time no see guys, I have a 4200+ coming next week hopefully to replace my 3200+.
I never found a good deal on a opty 165

but the 4200+ should do well.

Anywho I currently have my 3200+ @ 2613Mhz.

Hey, what is the highest, but safest voltage for a 3800+X2 Manchester? E4 stepping I believe?

The following has been done to the off-site roster:

Added badave
Added majakone
Updated speed for HothBase
Updated speed for Rolandooo

HothBase: My x1950 XGE ran happily on a 19 A dedicated 12 V rail. I do not know how many amps would be across all 12 V rails.

Domino: AMD says 1.400 V would be the safe limit for such a processor. I would not exceed 1.500 V on air, 1.600 V on water.

For the record... I am back in my apartment now.

think3r, I just wanted to thank you for the reccomendation on the linksys. man after you know how to do the initial set up the rest is cake. I was able to get a belkin usb wireless G adapter ver 5000 at fry's today. so I'm fortunate that I have the ability now to continue my work in the garage w/out any wires.

added bonus PS3 is now wireless as well
