Thanks for posting your results. It's great to hear from folks all over the world.
When people refer to "Vanilla" they mean "plain", basically unmodded, or it could be the card is the base model (and not the pre-overclocked version).

I started a new thread in the right section so the mods are easily accessible.

I will update that thread with the OCP as soon as I have fixed the image.
So, guys, yesterday I decided to put an end in a too-long-lasting process of stability searching. I added for testing Fur Bench and 06 3d mark. And, of couse, Warhead bench (for I still haven't installed original Crysis yet). The problem was: marks are running well, without mistakes, Warhead bench looped makes successfully about 30 cycles. But when starting running Warhead the game, crashes may happen in 1-2 hours: black screen and reboot.
I started with 756/1566/2916: fur bench forced system to reboot in 5 minutes; I set GPU 1 step lower - to 740, while shader domain and RAM were left without changes - successfully ran 30 minutes. Beign curious, I set Warhead-unstable value of shader - to 1584, and started furmark again - 10 minutes with no mistakes, after that a turn it off and switched to 3d mark 06. The frequencuies were 740/1584/2916; Fireflies forest ang Canyon flight looped to 15+15 cycles. Fireflies flew splendid, while flying ship droped system to reboot on the 13th run... After I set 740/1566/2916, Canyon flight ran 30 times with no mistakes.
So, hope, these are the final clock-values to my vanilla. Unfortunately, my sample appeared to be too poor overclocker :(
All hopes-only for Vmods
those of you hitting solid colors/other anomalities with my vmods..
check crotales ocp mod.. may be fix for
im hitting solid colors even on my unmodded ftw when pushed too far/great loads
i just 22ked my unmodded ftws ocp and as ive suspected.. ocp is a real mofo on the 285s especially @ air/even water.. though doesnt show its colors easy @ subzero temps
so whatever vgpu mod you guys go with.. several to go with.. if youre on air/water ocp mod is a must
thanks goes to crotale for the ocp mod
time to crank up vgpu
if you guys want higher mem.. ocp mod will take care of that too
ive gained 100mhz mem @ heavy load
you want lower temps? ocp mod will do that too
ive never been able to clock my ftw @ 1512 which would cause blank/black screens
here i am @ 1548 mem clock @ heavy load thanks to the ocp mod
overall 150+mhz mem gain @ heavy load @ stock air cooler
once again thanks crotale for the mod :toast:
So, if I make OCP mod it will fix the problem in step #3 with 150 ohm VR, because when I did it for 1.28v it was impossible to bench with my old settings (black screens) before step #3 and I've removed 150ohm vr.
Now with step #1 and #2 I can pass Furmark @810/1836/1512 with 1.24 vcore, but I can't pass 3D06 with 1.23vgpu and 2.11vmem.
Also Vantage, Win7 x64, @783/1800/1512 - 1.24 vcore http://img243.imageshack.us/img243/6...8001512oc2.jpg
GPU is under water with MCW60 and RAM sinks with 120mm fan.
Also if I make the mods of crotale, have I to remove your mods step #1 and #2?
What is the ultimate game/app for stability testing ( Furmark not included )
no more step 3 and even after ocp mod step 3 works better after step 2 is performed
but i still recommend step 1: the higher the vid bridging the higher the threshold
step 2 not necessary and only do it if you can/want to replace the vdiff resistor.. pencil is very unstable
at the moment i do not know how any of the steps affects crotales vgpu mod
if you dont want to find out.. go straight to crotales mod
ftw: 810/1620/1548 stable/sustained heavy loads/stock air cooling
ive pushed mem ~1577 but not sustain it
ocp mod lowered temps by at least 5 C
Wow. Huge thanks, crotale! That seems 2B the missing mod. :up:
I'll try that out later as soon as I know what's stable for my CPU/RAM. Too bad I'd have to take out the card again (that means to remove the waterblock... dayum).
Im getting a graphical glitch in crysis warhead, its like the textures are all warped and garbled.. memory too high ?

From my own testing this happens on this map ( the map where you need to goto a submarine ) and only i im doing alt-tabbing, and it fixes it self by moving the view around.
With stock-cooling unmounted, I've been only able to make VMod step 1 - higher vid bridging. I used electric-conductive varnish, containing micro-particles of silver; russian manufacturers call it "Contactol".

Shifting to the most interesting - the results:
VGpu:
before: idle - 1.055v; Warhead benchmark - 1.166-1.168; Furmark - 1.168-1.170
after: idle - 1.068v; Warhead - 1.233-1.234; Furmark - 1.235-1.236
Vmem:
no changes: idle - 2.10; Warhead - 2.12-2.13; Furmark - 2.13-2.14
Clocks:
before: 740/1566/2916
after: 756/1674/2916
Shader domain appeared to be the most voltage-hungry. Current clocks please me much better, than vanilla.
Thanx, Napalm.
PS temperatures: +2/3 Celsius in Warhead; +6 in Furmark
I gained NOTHING from the OCP mod... memory, core or shader... I lowered the resistance to 15K... Do i need to lower further?
oh you`re not the only one my friend...
^ may i suggest fixed resistor @ ocp mod? ;) (10k resistor)
core/shader not so much but mem is the one mostly/greatly affected by the ocp mod
@ inzer890 your welcome :toast:
