can somebody with a brain check this out.

can anybody help me with ocing my bfg 5900? i flashed to 5950u but it runs with crazy artifacts when i do that, so i have to bring it down in riva tuner. id like to keep the flash so the voltage to the fan stays higher, (and seeing 5950u is nice too!) but id like it to work properly at those speeds. Should i take it out, take of the heatsink, clean the gpu and add arctic silver 5? somebody help me!

Get some better cooling.Try a different bios.

Just taking off your heatsink and applying AS5 isn't really going to help you any. If the heatsink was rough on the bottom, lapping it and then applying AS5 may help a little, but probably not enough to substain the speeds you want. Watercooling would help. You could also try Artic Cooling NV Silencer4.

Of course better cooling will allow you to go farther, but also keep in mind your card just may not end up being stable at higher speeds, every card is different.

thanks. i think im just gonna end up sending it back to bfg and getting a new 5900 card. theyre under lifetime warrenty so it shouldnt be a problem. hopefully ill get lucky and ill get a better card that i can oc farther. also, can someone help me with ram timings? i dont know what to set my dram refresh time to or that other one with the 0t 2t 4t infinate, etc..... please tell me which one is the best.

Better flash it back to the correct BIOS before you send it back. Otherwise there is the possibility that they will tell you tough luck.

I still don't understand why everyone is so quick to flash their video card BIOS. Even though the chance is small, there is a chance that you can kill your brand new card.

Anyways how far did you card overclock before you tried the new BIOS?

Also notice PukePiles suggestion:

Try a different bios.

Some BIOSs are more stable than others. Which BIOS did you use? Have you tried any others?

yeah i tried a bunch, and the bfg's seemed to be the best i guess. i dont want to loose the tv out function if i dont have to, so another reason to stay with the bfg's. if you know any really cool ones, please advise me. i just dont understand how people can crank these cards and get serious benchmarks, and i have a pretty sweet rig, yet, im only up to 6300 oc'ed and my bfg non'oced i get 5900 in 3dmark03. WHAT IS WRONG!!!!

 

[Mr5oh]

Did you just downclock it until the artifacts went away?

Also did you try this with the original BIOS, before you flashed it.

Note that when you are overclocking video cards, generally you start low and go up (obviusuly), you will find a point that going with higher clocks results in a <b>drop</b> in scores. You may just have your card set to high, and is causing errors, nothing serious enough to crash your PC, but enough to hurt your score.

I think you should go back to the regular 5900 BIOS and slowly work your way up (Small steps 3-5 mhz, benchmarking after each step). Doing the GPU and RAM sperately. If you overclock both at the same time and then you have errors, you won't know which one is causing the problems. If you do this method, I recommend AquaMark3 as it doesn't take forever to run like the 3DMark series.

The link in my signature has overclocking results at the bottom of the page, I had just shy of 2000 point increase between everything being stock, and everything being overclocked (3DMark03).

What score are you aiming for?

im hoping to get around 7000 in 3dmark03. i think i just got a crappy card for overclocking from the company, and im hoping that the new card i get from them will be better. im gonna call up bfg and see if theyll send me a new one. does anybody have a favorite 5950u bios that they like best?

 

[knifetheglitter]

also, i just ran pcmark2002 with my p4 prescott with ht at 3.5ghz and got 7400 something as a cpu score. how the hell did your xp 2700+ or whatever beat my new p4? please tell me how to teak this puppy!

 

[Mr5oh]

how the hell did your xp 2700+ or whatever beat my new p4?

LOL!, no not 2700+ whatever, 2800+ XP, overclocked to 2.5 ghz for that test score, reason why its faster, ITS AMD, oh yeah. <b>Just joking.</b>

Ok seriously now, video card and RAM also still play a role into that CPU score, oddly enough. My RAM doesn't have great timings, 2.5-3-3-8, but it is running in dual channel. You will have to mess with your settings, I have found wierd things, like setting the AGP bus to 70 mhz, increases the scores, any other setting makes the scores drop considerably (71,72,69,68, can't figure our why, they all make scores drop below stock setting, but 70 for some reason makes them go up)(Also note that every machine is different 70 mhz AGP bus may not help you at all). Obvisuly disable any firewall, or antivirus tools while benchmarking. Mainly it just takes time, keep changing settings, and slowly overclocking more, and several hours later, you'll know what works best. Make sure to write everything down so you can keep track of everything.

Check out my overclocking results (link at the bottom of the page in my signature), you'll see both RAM and CPU scores go up when the video card is overclocked.

May try overclocking some more, but other than that I don't know?

Make sure you flash it back if they agree to take a look at it. You may want to come up with another reason to send it back, not sure BFG are going to be ok with the reason being it doesn't overclock that well. (In other words if they agree to swap it, I'll be suprised.)

[knifetheglitter]

word, i already threw on the 5900 bios , rev. 2, but when i check out all of the different bfg bios in sandra, they all say chaintech? isnt that weird. i hope if i send this one back that wont be a problem, or is bfg a part of chaintech?

Remember also, there is a point on all cards where you can keep turning up the clock but eventually performance starts to peeter out. I had my card clocked up to 4.25 at one point but the last significant gain I saw was at 4.19 (With the drivers I was using at the time). You have to find the sweet spot, the spot where you get good gain, and where going foward anymore is just not worth what its giving you. Expirement with diffrent drivers because they all affect overclocking diffrently.
