Just got a BFG6200oc

post #1 of 19
Thread Starter 
Hi

I bought a BFG 6200oc 256mb to replace my old ti4400, because it crapped out on me. I was hoping for a performance improvement but the 6200 seems to have really poor performance. It gets low 7000s in 3dmark01 and 1100-1200 in 3dmark05. I though that at least it would match a midrange card two generations old. I did a fresh windows install so I'll have to run it again and see if a clean drive will improve anything.

When I tried overclocking it the whole system froze and after looking through a lot of forums I find out you have to use old drivers to be able to overclock it. Isn't there another way? I read that one person changed something in the bios and overclocked it that way.

The gpu stays very cool so I know theres a lot of potential for overclocking. I don't know why nvidia decided to keep people from overclocking, isn't giving the 6200 4 pipes instead of 8 enough to distance it from the 6600?

My specs are:
P4 2.4
Asus P4P800E deluxe
512mb pc2700

I have the same card except it's a bfg 3dfuzion 6200, only difference is that it didn't come overclocked when I purchased it.
I also had low 7000s in 3dmark01se, and about low 2000 3dmark03 scores before overclocking.

The stock clocks were core/mem: 350/400.
After overclocking using Coolbits 2.0 and attaching a 80mm fan to the heatsink, I was able to achieve 465/670, and my scores in 3dmark01se went up to 10700 and in 3dmark03 up to 3400.

The scores are still pretty low but I purchased my card for $50USD, so I got what I paid for.

The new 6200s, with nv44 core, can't unlock 4 pipes like the old 6200s with the nv43 core, so they are pretty much low-end graphic cards that support DX9.

I flashed my originial 6200 bios with my own modified one, using a Nvidia bios editor, to change to stock clocks to new values, because I also had a lock-up problem while trying to overclock my core in windows. I guess thats a solution if your like me, and don't like using older drivers.

I feel for you, I hate using this 6200 but once I save enough, I'll be looking into some 6600gts or even 6800s.

I made a mistake, I meant 1100-1200 in 3dmark05 not 03. I havent tried 3dmark03 yet. I'm curious what your score was in 3dmark05, did you try that yet?

So is your fuzion a nv43 or nv44?

The bfg allready comes with a fan instead of just a heatsink. It cost me $130 from Best Buy (itll be 100 once I use the mail in rebate). Which is still a decent deal.

Can you tell me more about the nvidia bios editor? Does it have to run in dos?

I can't help but notice your running 3.2 on a 2.0 p4. Is that on the stock fan? In the bios on my asus mobo theyres an option to overclock automatically, you just pick 5%,10% and so on, I think it would adjust voltage accordingly. I'll try and see if my 2.26 can get anywhere near what you're running.

Heres the bios editor:
http://www.majorgeeks.com/download3122.html

It's very easy to use. Read your original Bios, and then just change the core and memory frequency and save it as a .rom file.
You must run nvflash (http://downloads.guru3d.com/download.php?det=896) with a boot disk, so yes you need to run it in DOS. Nvflash, flashes your video card's old bios with the new edited .rom file you created with the Nvidia Bios editor. If you decide to flash bios just PM and I can help you or just google on flashing nvidia video cards.

My 3dmark05 right now is like 1374, but before overclock it was probably around 1100-1200.

Its a fuzion nv44, so I'm also stuck with 4 pixel pipes.

Actually, I have a prescott 2.4a processor overclocked, but I bought an aftermarket cooler called the Coolermaster Dream III, since my case was too loud with stock hsf, but I wouldnt recommend my new hsf, because the heatsink is not all that great and I still have pretty hot temps.
I wish i would have purchased a Zalman or XP-90, I might of been able to reach a higher overclock.

I overclocked through my bios, by upping the front side bus (fsb) from 133 to 174. Increasing my cpu clock from 2.4ghz to 3.15ghz. I left the voltage at 1.3375, since prescotts don't need much voltage. I also upped my ram voltage (vdimm or vmem) from Auto to 2.7v, since I was running my pc2700 ram past it's rated speed of 333mhz to a new speed of about 350mhz.

Your TI4400 was more powerful than your 6200. Thats why your scores arent good.
Very nice!

Stuck at 3.15, since my temps go over 65C after crapping out in prime95.
I'm planning on getting a ZALMAN CNPS7000B-CU 92mm or Xp-90, and some pc3200 ram, lol I have pc2700 right now .

But yeah, wowza your right these cpus are insane Oc'ers.

Oops, Srry, forgive for going offtopic.

I'm definitely going to need some help changing the bios, because I have like zero experience with using dos. If you could give me some more info or a link to it, I would definitely appreciate it.

I'm more of a console gamer so I can't wait until ps3 comes out, but I still play games on the pc. The one game I really wanted to play was call of duty 2, because it looks so awesome on the xbox 360. Will the 6200 be able to handle that? I tried playing the battlefield 2 demo and it was playable on medium settings.

I don't know why the ti4400 is more powerful. The 6200oc is running at 375 vs 275, its got twice the memory, and 2x400mhz ramdac instead of 2x350mhz. AGP8x vs 4x. I think the 4400 has faster memory transfer though. Still it seemed to me the 6200 should kick the crap out of the 4400.

Perfect guide to flashing:

http://www.overclock.net/faqs/26896-...hics-card.html

Just read that, and you will be good to go.
You can flash as many times as you like so if your not sure on how much to change the core or memory frequency by, just flash the bios with small increments in frequency.

Find a stable memory overclock in windows, and use that as your memory value when you flash the bios.
And for the core overclock, since you can't overclock the core at all in windows since it will lock-up, just keep flashing with small increasing (5-15mhz) in frequency.
Then play some games for awhile to see if its stable and artifact free.

That's how I finally achieved my stable 465/670 overclock on my 6200.

Goodluck.

Ok I went through all the steps. I only edited the clock speed to 400mhz, I didn't change the memory since I can do that in windows.

I type in nvflash (filename of edited rom). It shows me the message saying are you sure you want to update, I press y then it says error: supported EEPROM not found. I tried it twice with different filenames with no luck.

Damn you nvidia for making me go through this sht just to overclock my card.
