best of luck with the rma :-)
Thanks pal!
Yes they took the card and tomorrow i ll know if everything went ok.
From the style of the seller when i told him that i had no signal on LCD and fan jet blowing i figure it goes straight for RMA...
i also RMA'd the new DFI *i bought cos it was missing accesories+ had some scratch so i think it might have been under test/review or so0mething.That went OK and i get a new one tomorrow!

Hopefully i get a new 5770 too and i ll be on the modding again!!!
Most propably i will be getting this one.http://www.plaisio.gr/Computers/Hard...ess-1GB-V2.htm
How do you find the new VR sircutry positioning/cooler?I think it might be OK but it will definatelly be GREAT for aftermarket coolers,a place where the 5xxx family had serious problems.So?


EDIT:Out of the corner of my eye i saw a couple of 4770s 79EUR each...I was really tempted i must say...If i had some EUR i would grab two of them ffor some modding/benching;
Next to them i saw 4650 ffor 80EUR!!!!!!!!!!!FAIL...what were they thinking???


*I forgot my 1283s backplate on the mobo box and i realized after returning home....Lucky me i went back before going training and the box was still there and the kind sellers let me get it back...

I used that rivatuner thing, forgot I had it book marked from a couple days ago. Works pretty good.

This has been an adventure lol,

So is it keeping your card from downclocking or are you still trying to figure that out?

Nope its working great. Actually left it folding allday at 837/1674 (core, shader) with not early end wu's. Was able to run all benchmarks as well.


Now for the next issue. I think I need about 0.1v more for the ram. Im on the evga gtx260 FTW bios right now which gives me 2.10vdimm which is a slight bumb from stock. I gotta find the bios I was running that gave me 2.224vdimm.

With 2.10 I top out at 1250memory, with the bios that pumps 2.224vdimm I top out at around 1350memory. That or I could try and figure out the vdimm voltage mod. Just havnt scene much on it.

I noticed with the high core and shader clocks in my benchmarks the score doesnt go up much after about 780 or 800 core. That is until the memory really goes up. I think if I got the memory back up to around 1350 that I could take more advantage of the high core clocks.

Mmm..shaders will like getting more bandwidth from mem as well

That also.

I may be just limited in the ram oc anyways. I was poking around some more and may have been reading the wrong voltage.

Around the memory chips some resisters read 2.24v and some read 2.148v. Not sure which is the memory voltage.

Anyways everytime I set the memory above 1250 or 1300 or so I get the distorted windows screen and have to reboot. Tried it at stock or close to it core and shaders as well. The one time I ran at 1350 memory could have just been a fluke or something not sure.

Still Im pretty satisfied with the results. Pretty decent oc for some tweaking and a cap job. Allthough I think more caps are in order. With 1.34vgpu and a high oc it starts squealing pretty loud again while folding.

With the RAM voltages.. what you are seeing is :

vDD = 2.24v [thats what you mod'd ]
vDDq = 2.148 [reference voltage]

...with the GTX+ they have 2x vMEM controllers same as reference series 48xx GPU's.... 1x for each mem voltage. While raising vDDq is not always warranted...it definitely can boost mem clocks a bit, with a small increase..[ie- not more than .065v or so].


* try input caps [16v] this time ...help the inductors on the "in" this time
post #898 of 1336
So I should cap all the memory power resisters as well and this will raise it a tad?

Not sure which ones would be the key ones to mod. You point me in the right direction.

This poor card is looking more and more like ol frankenstein lol.

EDIT: Guess it would be any of the larger ones that I get the proper reading off of correct. Do all the ones I get the 2.24 and 2.18 readings off of and it should be good to go I assume.

You have 2x caps that = 2.24v / IC ...and 1x cap that = 2.14v /IC correct?

...just measure from IC to IC..across the PCB..checking for drooping voltage on the mem circuit..

ie- 1st IC v= 2.24
last IC v = 2.21

...^^ this will indicate a problem that caps can fix. If anything...and all it well I would cap the vDDq first since its your lower of the two voltages.

Thanks CL3P20, Ill play around with it this weekend.
