Posted: Thu Apr 16, 2009 3:05 pm Post subject: OC'ing a Geforce 6200
I moved this post here instead of replying to the related post in General Hardware.....thought this section was more appropriate.
My friend took my advice and ordered a BFG GeForce 6200 OC 256Mb PCI card from TigerDirect and installed it. Unfortunately, it won't softmod to a 6600....it's the (A1,4pp,3vp) NV44 64-bit variety, but that's OK.
His problem is this......the core clock speed(350Mhz) is hardlocked and will not OC. If he goes even 1Mhz the machine gives him a BSOD and has to be rebooted. Rivatuner as well as Coolbits give the same outcome....the only difference being that Coolbits will BSOD the machine if all he does it try to "Detect Optimal Frequencies". The memory(532Mhz) OC's just fine by itself. Older drivers up to, I believe, 81.33 will let him OC both core and memory, but he'd like to use newer drivers. BTW, if he chooses to "Detect Optimal Frequencies" with the older drivers, he gets a result of 611Mhz/1.03Ghz for core/clock, which is ridiculous. Garbles the screen upon reboot. Even if those speeds worked, I don't think the HSF would keep the card cool enough.....he'd have to at least do a volt mod, and that just isn't worth it on a PCI card. I was wondering if he could make a backup of his current BIOS, modify the core/clock speeds and then reflash it, could he use newer drivers without any problems OC'ing the core? Is there a BIOS somewhere he could safely use to unlock the core to OC? We've checked Mvktech.net with no luck.
We've noticed that the 16x.xx series Forceware drivers work best for his card and rig setup. They all give about the same performance in 3DMark06 give or take 5 or 10 pts, and also give better performance in the older games he plays. But there's no way to use these newer driver versions with the core being hardlocked as it is. I just figured if he was to do what I stated above, this would solve the problem with OC'ing. Would this be a safe bet, and if not, is there another resource to find a BIOS with the specs of his card? Thanx.

Mine is oc'd using RivaTuner to 440/600, with temps running (while playing World of Warcraft at 1280x1024) at 34-40C.
I use the XTreme-G_185.20_XP_32bit drivers w/RivaTuner, and I used the ATiTool to find the highest settings I could run w/out artifacts and garbling the display.
This is a stock card/fan combo, no extra cooling, and has been running fine for over 2 months (Except drivers. Been updating those fairly regular).
I don't have a smoking system (FPS at that resolution is about 20-30), but it works OK for me.
Next is either mineral oil cooling or ...( Who knows what the future will bring).
BTW, the same clock settings work great under Linux, too. Running Slackware 12.2 and 182 series of drivers from Nvidia on this dual boot box.
Have you tried dling a bios editor and then flashing the bios with an oc'd one? _________________ Asus Sabertooth 990FX Rev. 2.0 - AMD FX 8120 - 2 x 2gb G.Skill 12800 ddr3 - Corsair 1000w PSU - Cooler Master HAF Case - 128 GB Corsair M4 SSD - 150 GB Raptor - 1 TB WD Black edition - 2 x Evga 580's - 37" Vizio - Win7 Pro 64

Have not tried with another bios, because neither he nor I have found one for this card on the web. If you can point toward one we'll give it a shot and post back the results.
The card he has came factory oc'd 350mhz/532mhz. I just noticed today that the reference design is 300mhz/532mhz. Never cared to look that up, because factory oc usually means 10mhz core or core/clock....another words, not much. But 50mhz is a fair jump.....however, I really think it can do a lot more by what others have said, but touching the core by even 1mhz with any drivers above 81.xx BSOD's the machine. The memory will do 650 fairly easily...beyond that there are sporadic lockups here and there. _________________ Windows: A 32 bit extension for a 16 bit patch to an 8 bit operating system, originally coded for a 4 bit microprocessor, written by a 2 bit company, that can't stand 1 bit of competition.

You could always dump the bios and change the clocks there... The only thing I'd be worried about is why you can't OC. If it's a driver problem, a bios flash is the way to go. If it's another issue (eg power), there's a fair chance you'll end up bricking the card.
What are the temps like? Does it have external power? I'm not sure that it'd get enough from a PCI slot for any major overclocking... _________________ CPU: i7 860 @ 3.8ghz (Corsair H100/Noiseblocker M12-P)

Would you mind too terribly explaining how to accomplish this?.....I guess we're just dumb, but neither one of us understand the difference in doing this and just OC'ing the card using Rivatuner/Atitools/Coolbits. Are there other options besides just the clock speeds that can be changed with the stock bios to maybe eliminate the problem?

The only thing is we've been unable to find a 6200 bios for his card, if you could point us to one to try, we'd be willing to try that first. And as far as why the OC'ing of the core isn't possible, I've read all over the internet that it's hardlocked.

I just read an issue last night of one person with a 250w PSU in a Dell who thought this was, in fact, the problem. However, it wasn't totally confirmed.....and that's exactly the PSU he has. Would OC'ing a "PCI" card really make a huge difference on power output? I can see where an AGP or PCI-e card would for sure, but not in this case. Besides, I've seen lots of examples where others have been limited to PCI and installed an ATI x1550 PCI card with the same PSU with no problems. Those cards say they require a minimum of, I believe, 300w....could be wrong.

Well, with just the memory OC'd to 650mhz, the temps remain around 45 to 48 degrees celsius under load. But then again, the games he plays.....e.g., Sims 2(Which is actually the most demanding game he plays), aren't that graphic intensive. The jump in performance in the Sims is an average of 10-12FPS with just this memory OC.
I stated before that with older drivers he's able to OC both core and memory, but last night we tried with ATITools for the first time and couldn't do it. Seemed to have worked with Rivatuner and Coolbits. Tried with drivers from the 7x.xx's thru the 8x.xx's with no luck.
The long and short of it is, by what we've read, there are tons of people with this problem concearning the 6200, and if we could figure it out, we could help alot of others. _________________ Windows: A 32 bit extension for a 16 bit patch to an 8 bit operating system, originally coded for a 4 bit microprocessor, written by a 2 bit company, that can't stand 1 bit of competition.

I have 6200 512MB DDR2 AGP, I cannot OVERCLOCK with newest driver nor olds, well i have tried the 196.XX and XTreme-G 190.62 XP 32bit with no success. I tried with RivaTuner to increase memory clock and core but as i said, no success. Maybe someone can provide me a way to overclock this card video?
This is quite odd, I'm using the exact same card, nvidia Geforce 6200..256 mb, 64-bit, ddr2 vram. I have mine OC'ed and stable at 348/419. Could it be possible you have a rare revision of the card, or maybe a defective one?
P.S. i used Rivatuner 2.24 to OC mine using the 195.62 XG drivers, dunno if it makes a differnence but im under windows Xp x64 temporarily, this is where the OC'in took place. _________________ -------------------------------------
