I just overclocked my saphire ATI radeon 9600pro from 400mhz clock speed to over 510 and the memory from 450 mhz to 526 mhz, is this safe? i had no idea you could get it so high, i did this using the atitool to find the maximum overclock for the core and for the mem, and the core kept on going after 511 but i stopped it becuase i was scared, and my video card does not have a temp sensor.

P.S. ive been scanning for artifacts for 10 mins now and none, should i go higher?lower?

I would do some heavy gaming for at least 2+ hours. Run the game on the highest settings you can do so that you are getting 60 - 80 FPS. If you don't see any artifacts, then it is usually good. Also, run 3DMark05 and see if there are any artifacts in there.

In addition, you shouldn't be overclocking on a cheap PSU. You have sufficient power, but an inexpensive PSU might not be able to sustain the necessary power for overclocking. Post all the info on the side including amperage. Also, download SpeedFan from my sig and post the voltages it reads.

i already have speedfan, here are the voltages

ive also been playing half life 2 on highest setting 1024x768 for an hour and 30 mins, and css went from 57 to 68 fps in video stress test, and hl2 shows 71 fps

Your +12v is way too low. Verify the voltages in the BIOS. If you remove the overclock and the voltages don't get better, you will need a new PSU to prevent damage to your system components, especially your video card.

thats not low that was the normal for my last psu (300watt) and this is 11.84(500 watt)

TheMatt

11.80v on the +12v is way too low. And Ultra PSUs are not reguarded as high quality on TSF. You should both look into new PSUs.

i had a bestec i am sure that it is a great improvment on that

11.8v is absolutely fine, the atx spec is for 11.4v-12.6v for acceptable voltages. also, mobo sensors are incorrect, and most of the time the actual voltage the psu is giving out is higher.

linderman

dude its your money >>> fire it up


a short time go I had upgraded two pentium "D" systems that were amost identical spec, with antec True Power-2 550 watt PSu's

during heavy gaming one would droop to 11.4 the other 11.6 Antec willing took them back for RMA after I emailed the screenshots from everest & digital pics from bios

I got cold feet becasue I am holding the free parts and labor for one year on those two machines, they both got Antec 650 Trios installed I wasnt about to take any chance frying video cards or motherboards with the tru power-2's

I posted the same finding here at TSF; much to many peoples surprise they thought I was being over cautious I am sure, low and behold a month and a half later; the antec tru powers and smart powers were flopping all over the net from stress!

simply put; you cant stress a 70% efficient PSU with overclocking and get away with it!

just be man enough to come back when the smoke starts rolling and say "geez you guys were right, so maybe someone else can learn from your mistake"

hell, I did just what I am asking you, I was warned not to run D's with a 550 by our manager (Dai) and BlackDuck but I didnt listen

but I was open minded enough not to keep pushing them unitl they croaked, when I got the RMA's units back, I sold them in used budget systems that dont push them!

good luck >>>>>>

yeah i think it's a great powersupply i've never had any trouble with it, mabye i just got lucky though but i think it can handle it, i got my cpu running at 2.3ghz from 2.0 right now and my graphics card is at it's highest stable overclock right now which is 500 core from 400 and 500 mem from 450(memory heatsinks soon going to be ordered:) that should give me another 50 mhz or so i think out of memory).

linderman

well I am happy to hear you are satisfied, thats the goal in all this!


enjoy

One thing I have to ask, are these voltages under load or idle. Idle voltages should be very close to 12v in your case, and load voltages are what you have to watch out for. Try gamming for a while and then measuring the voltages.

Back to your original question Adam, other than the voltages, everything looks fine. You can run the artifact tester in ATI Tray Tools to test if overheating is causing GPU instability. But I highly recommend you look into a new PSU. For both those systems (I g0t 0wn3d as well), the Antec TP3 Trio 550 w is a good quality supply that is inexpensive.

Evrything in my computer runs very cool.<cpu runs idle 25 c and under load 37 c, and case temp is 16. buy if i must get a new power supply i will, ill start looking around on newegg.

linderman

just for the sake of discussion; how much of an improvement did you see with the overclocking of each component

small improvement medium improvement huge improvement ?



EDIT **** Adam check your PM's (upper right hand corner)

adamb_135

umm i went from 52 fps to 67 fps in css with overclocking video card, cant really notice an improvement from the extra 250 on my cpu, its probably so small i cant even notice the diff.

linderman

the video improvement should have been noticible performance bonus

I have heard anytime you can get a 10fps increase its noticible ?

adamb_135

i said i notice no difference from the cpu being oc'ed but i do with the card being oc'ed

linderman

yeah gotcha ya
