Adding 6-pin to 9800gt

Nemesis881 · Jan 7, 2012

So I have one of the "eco" 9800gt. The 6-pin adapter isn't needed...until I start overclocking.
I just bought an Arctic cooler VGA heatsink/fan. While it is out, I would like to know if there is a way to rig up a female connector to the PCB. There is a place for it, but it's just soldered holes in place of it.
I remember seeing an article a few years ago where someone did this.
Any tips, tricks, articles, or personal experiences would help a lot. :toast:

Do the leads from the holes for the 6 pin actually go somewhere?

Jstn7477 · Jan 7, 2012

I heard some people have blown up their cards by adding a 6 pin connector to an "Eco/Green" card. The card is wired to use all the power from the PCIe slot, instead of being dependent on an external connector. The boards are usually designed for either/or, not both.

Overclocking it probably won't make too much of a difference considering it is a 9800 GT and you're running it on a Athlon X2 4200+ with DDR2-533.

Not sure if it leads anywhere. It hasn't been out of the case for sometime. I know there is a place for it though. Just cleaned all my fans a few weeks ago.

I guess I will make due without. It IS overclockable to an extent but not near as good as the non-eco models. Also, my monitor is only 1440x900 res. With my processor and GPU overclocked, you would be surprised how much of a difference it makes. That's another concern since I have the processor sucking more power down as well.

Jstn7477 · Jan 7, 2012

I doubt you're using anywhere near 600 watts with that system. I run a 4.5GHz 2600K quad core, HD 6970, GTX 550 Ti and 6 HDDs on my Corsair TX750 and it doesn't flinch.

I would overclock the CPU and RAM definitely, as they are likely a much bigger bottleneck than the 9800 GT.

The 6-pin won't help. The reason the card overclocks like crap is because the core voltage is dialed waaay back to lower the power consumption enough to run off the slot alone. AFAIK, there isn't an easy way to raise the core voltage on the 9800gt.

add 6pin and bios flash?

you could BIOS flash some of them, but only set amounts. IIRC it was 1.05v and 1.10v

Thanks for the heads up guys. Due to my awful RAM, I can only get my cpu to 2.64ghz..Which isn't to bad for what it is.

My GPU actually handles OC fairly well IMO.
Stock speeds are 600/1500/1400
Most stable OC to date is 705/1800/2030.

Just threw on my new Accelero L2 pro cooler on a few hours ago. Gonna try to push it a little farther.

Be careful! I wouldn't worry about the power supply but moreless the board with the added stress and current being pulled through the slot.

Nemesis881 · Jan 8, 2012

Not really too worried about my mobo going out. If there isn't enough power for the card, the whole system shuts off plain and simple. I have had this happen on some suicide card runs back when I first got it lol. Anyway, I lowered the shaders to about 1770 and started maxing the memory because they use the least power on the card and I have had the best OC percentage on them. Got the mem up to about 1170 (2340 effective!) before the artifacts and crash happened. Probably gonna set it at around 1100 and leave it. my low res monitor isnt benefiting much from the memory. Now, I have been trying to figure out what to tackle next. Max core? Max shaders? link them and max together? been googling this for a few hours and cant find any definitive answers. I am leaning towards shaders but I'm still not sure. The games I play mostly are: Starcraft 2, Dota 2 beta, left for dead 2, Skyrim, and Call of duty 4. Running them all max except for starcraft 2 because it is processor limited. When there is a lot going on I get 40ish fps in all of those games basically. Not bad, but every little bit helps.

Those are not bad clocks, my 8800GT (which is same card as 9800GT) clocked ~700/2000, and it had 6pin.

ViperXTR · Jan 19, 2012

late reply but, just from experience, that CPU is bottlenecking the card. My X2 5200+ overclocked to ~3.2Ghz is already barely using the capacity of my ol 9600GT (also overclocked to ~750Mhz) even for some GPU limited games.

anoobarak · Jan 19, 2012

A 8800/9800 GT with a 6pin connector would hit close to 800 Mhz on core. Pencil modding one would increase the headroom even more. But yes, it's incredible that a dated dual core would still bottleneck that card. I know my old athlon x2 245 did bottleneck my 8800gts 512
