IDK what the voltage was for the XFX top dog or whatever was, I did do the pencil mod on it but no hard mods, maybe FAHMon was off, I only meant stock for voltage, not stock clocks

XFX TopDog [not AlphaDog] edition is 1.1v default GPUv..

Yup..shader clocks are what determine PPD..even a 250mhz gain in GPU core speed will not net you a single point. What you said makes sense just fine.. 1998mhz shader strap on a GS does indeed produce 6k PPD, regardless of core speed.

.. pencil mods typically have no effect on the voltage circuits standard PCB or not. I have not seen any to increase GPUv for the G92 core..whether GS/GT or GTS.

ah, then I have learned something, I didn't know the stock voltage, just the fact that it overclocked pretty well. On my 8800GTS I have found I can get higher shader clocks by downclocking the core and memory, usually nets about 100 more ppd

My 8800GTS has put out close to 5500 once, most of the time its around 5200ppd

GTS's have a 3phase power supply for the core, compared to 2phases with the GS and GT..they make great vmod'ers. You have to clock the shaders higher with the G80 to produce the same PPD as a G92..~150mhz or two shader straps, separate their performance.

ie- G92 8800GT with shaders at ~1700mhz will produce about as much as a G80 with shaders at ~1850mhz.

*and, Yes..clocking memory down saves quite a bit of 'current' ..that can be applied to the shader OC.

...Sorry, I dont want to overwhelm you or anyone reading the post..just need to get some things out... I have been doing a lot of tests with the GS lately. PM if you ever need help with your OC or vmods.

I will, I just bought/traded for a socket 939 sli board with 512 of ram and a 3200+ processor. Once I buy my new powersupply I can put my sig PSU on the sli rig and then get 2 8800GS's.

Once I do I will be sure to PM you about the volt mods, I am looking for 12k ppd from this sucker. Oh and one other thing, I might just buy 1 8800GS and use my 8800GTS for folding as well when I buy a 4850.

I remember reading a post of yours about different cards folding at the same time and will probably need some help setting that up

**CL3P20** · 11-05-08

Well so far, the only two GPU types I believe; that you can mix together and not foul up your PPD, is.. G80 any flavor + GS/GSO G92. Reason being is that you can flash the G80 with the G92 BIOS from a GS or GSO..this should fool the client into believing you have the same 2x GPU's. I know the BIOS flash works..just havent tested the PPD out for mehself.

If that doesnt fix it ..then all hope is lost for mixing GPU's for effective PPD.

well, the day is quickly approaching that mortimersnerd will finally overtake me.
its giving me 1.7 days.

i kicked it in high gear the last few days and commisioned a few friends GPUs but it looks like it was just delaying the inebitable.

You might get an extra day in there...my 4 GPU folding system is only getting about 8k ppd due to driver issues. I'm probably going to take it offline tonight to fix the problem but I should be at full capacity by morning tomorrow (40k ppd).

Sorry Bro and congrats on the 1mil.
