Yup..OCP mod works just fine..and you dont need to remove the stock ones...just get the same resistors and stack them right onto the stock ...better be ready for some heat though..and better mosfet cooling.

lol maybe I should set up my thermaltake bigwater that im not using with my extra bloodrage waterblock and make a seperate loop just to cool my mofset

got 3rd place with 3559 3dmarks at 922/2160/1160, gonna do some more benching tomorrow and try to find another card online that I will consider trying this OCP mod with

cough*evga*cough... Dual-slot 9600GSO They have a wonderful PCB layout..some with 4x2 power phases [core/mem]...Dual-slot SC/GSO would be

*then after I flash my GS's to GSO's...we can compete

I was using the 195.39 driver when I got the best scores, also tried the 191.07 & 190.62 XtremeG drivers but score was down a few points.
Got to a better hardware store today & stocked up on some VRs, so I can put the 500 on instead of the 10k. They were out of 1.2k smd resistors so I got some 1.5k, from what I read should still work fine for the OCP mod.
I'll do the vgpu & vmem to try out before bothering with the OCP though, baby steps...

exactly FTW, the OCP scare me, no way im trying it unless I have a backup card as my disposal, my core gets up to 1.42 at point without enabling OCP so I doubt I could get much higher. maybe 1.43 without crashing

Re-capping [or adding 2ndary caps] will help you inch closer to OCP without mod...OCP will trip if the delta between droop and overshoot voltage is large enough...caps help to minimize this.
post #37 of 553
what is the number of the onboard resistor that the caps would go over and what is the best type of cap to use?

edit: weird im able ot post with any vgpu under 1.6, I jsut posted at 1.55 but didnt want to risk benching, im at 1.45 now with 2.14vmem-ish gonna see if vantage will run without enabling OCP

wow i need a job

edit again: according to my multimeter the vgpu hit 1.48/1.49 under load during the 2nd vantage "new calico" test, all without an OCP mod, very peculiar but not complaints on my end

OK I did the vmem mod & re-did the vgpu. I upped the memory to 2.048 from 1.989 to make sure it worked but haven't played with mem clocks yet.
I was running ati tool while upping the vgu, got as far as 1.2 V & clocks were stable at 821/1998 when I looked at the card & noticed my heatsinks on the mem chips were sliding off...
One fell off while i was doing the mod so I took it apart & reapplied TIM. I used as5 since it seemed like the thickest & stickiest I have here, did I use too much or should I be using something else? The mobo is parallel to the floor so the card sits at 90° angle in the computer.

these get really hot voltmodding so Im not suprised the TIm lost adhesion, any TIM will probably liquify at high temps especially if its near the mofset. I would use a thermal adhesive or if you dont have acceess apply with regular TIM and superglue the the heatsinks at the corner of the chips and let sit for awhile

I've gotten memory up to 2.2 but it doesnt seem to do much past 2.1 2.15, right now im fighting so incredible instability, not sure if its CPU based or because of my Voltmod but im having to take my Mobo battery out a lot to be able to post at my overclocked settings

memory might be the cause of the isntability because I dropped it down to 2.15 again and it booted right up, going to run soem more vantage but I might have found the cieling for my clocks at:

930/2216/1175

, Im gonig going to see if i can up the shaders a bit and work on the memory but at this point im considering trying to get my CPU up to around the high 4.5's or 4.6 to keep the 9000 point dream alive, only around 350 points away

I saw on hwbot that you dropped me out of 5th place, I'll have to try the dab of glue to keep the sinks in place so I can keep the race to the gold going...
