To tell you the truth I'm getting tired of waiting on a solution for these cards and I may just sell them and go for two x1950xts.
Kain-
Ok I see now. LOL I do that all of the time, to old interforum copy paste. I haven't OCed my HIS yet, I will probably tommorow after I get my new RAM up and running.
Nicepun-
I was as frustrated as you, so I got the HIS. It is a really sweet card, so if you RMA, go with the HIS. Unless you can afford those X1950XTs, I can't remember how much more they are.
They start at 250 on newegg, up to around 300.
How do the HIS OC compaired to the Sapphire. Also, the reason for my frustation is the lack of OC proggies. The latest ATiTool supports all cards, even nVidias, except the X1950Pro...:slapass: , then again for the price of two X1950XT I can get a 8800GTS or even 8800GTX.Quote:

I can oc mem to 823 in winclk but core and mem values always drop to 200 or so whenever I try to oc the 2nd card.
1) It is _ABSOLUTELY_ no related to memory timings. It is related to buggy ATI VGA BIOS and not reading the documentation, which clearly says about it and provides a workaround:
Due to VGA BIOS specifics memory clock frequency of all currently shipped RV560/RV570 display adapters cannot be changed any third party low-level overclocking tool using VGA BIOS overclocking methods without causing immediate display image corruption and subsequent system hang. The only currently known workaround is controlling the clocks by means of the Catalyst driver to control the clocks instead of VGA BIOS. This mode can be activated by power users by setting EnableDriverLevelClockControl registry entry to 1.
2) Don't expect to get it working in RT for the second card, if it doesn't work in WinClk. Low-level o/c won't work due to BIOS issues. And driver-level workaround, which is implemented in WinClk (and can be also enabled in RT by using EnableDriverLevelClockControl) depends on ATI Catalyst's possibilities. And the Catatlyst's own overclocking interfaces are _terrible_ and not dedicated for Crossfire mode at all.
Meaning that we're still SOL!!!! Well I think I'm just going to sell them and get a 8800GTS with the Dell deal which will be around $400 shipped.Quote:

I have 2 of these (Stock speeds I've been running Windows Vista so I don't want to mess with Overclocking them yet) and I absolutely love them.
Why don't you use Rivatuner v.2.0 RC16.2? It works!
And ATI Demo The Assassin is excellent stability testing tool!! I finally got two Zalman ZM-RHS1 sets of 8 memsinks. I attached the higher ones to memory and used the extra thermal tapes to connect that black sink that was constantly falling off from VRMs (stupid idea to use hot glue :nono: ).
Now I can pass The Assassin demo at 661/1480 which before gave me a black screen!! I also did some easy soldering work, small drop of solder (frustrated to wait conductive ink) so my Vgpu is now 1.266V (before 1.25V). Used this picture, soldered the point that should give 1.32V.

Nicepun-
I haven't OCed the HIS just yet, but I will keep you posted on this. If you guys haven't tried it yet, the new ATI Tray Tools Beta version supposedly supports the RV570 core, but I don't know about the memory for the X1950 Pros.
Well, Im working right now at 670/770 without problems overclocking with ATI Tray Tools (not even a problem, even ATI tools , Overdrive and Wincklck didnt work for me, ahh, also Tried Riva Tuner).
My ram need some ramskins and then Im overclocking it more.
Core Still can go higher with Water Block (thanks to temps, But Im afraid im almost touching the point where i need more voltage).
Have you tried all night stability with 3DMark06 or the Assassin demo?Quote:

i think i've just found out why my cards clock so badly comparedt to other peoples...
just dug out the multimeter and testing one of the cards, it seems that it's only getting around 1.2V :(
anyone have any experience with voltmodding the reference ati cards?
the placement of resistors seems slightly different to the pictures in the guides i've seen so far

Well my friends I'm afraid I decided to part out. I bought a 8800GTS from Dell for $400 Shipped. I'll be selling one of the X1950 Pros, the other one will be going to my Back-up Rig. My Back-up Rig has a 7900GTX and that will go on sale as well. I just got tired of tinkering and not having a definate solution. It was fun while it lasted. Adios Muchacho!!!
Sorry, but X1950 Pros default Vgpu IS ~1.250 Volts. :fact:Quote:

Well, I havent tried the Assasins Demo. BUt sure I have run several loops of 3dmarl 05 and 06 without probelms all night.Quote:

Downloading...
That multimeter is reading on around %3 error, so that seems right to me.....
i. e. [(1.250-1.209)/1.250]*100=3.28%
I'm not sure if you guys have seen this, nor do I know if the Powercolor PCB is the same as most of the X1950 Pros (has the Rage Theater chip), but here are some voltage mods with pics for the resistor soldering points.
http://www.vr-zone.com/?i=4190&s=7
It shows that they could get it up to 1.85V and from this article the Powercolor's voltage profile reads:
GPU defaults at about 1.28V and memory at about 2.08V.
Well, downloaded Toy Shop and Assasins Demos.
Both of them runned without problems at 665/1465.
Runned 5 loops each one without artifacts, crashes or something like that.
I really doubt I have stability problems since I have been playing for hours demanding games like FEAR and I have runned several 3dmark 06 and 05 loops.
according to uni-trend (UNI-T model UT60E), this meter is rated as having better than 1% accuracy
http://www.uni-trend.com/UT60E.html
i think the arrangement of bridges on my cards are giving them lower voltage - also showing in the non existant overclocking abilities
other cards are able to get much higher than 601 on the core
i'm a little unsure about trying the voltmods because the little bridges or whatever are in different places to the ones shown at vr-zone or pcmasters.de
[edit] after thinking about it i might just leave it as is :(
i think i'd have to break out the soldering iron to move some of the bridges around to give myself more options :shrug:
I'm not going to mess around with physical volt mods until it is a last resort....surely ATI Tool or Tray Tools will support upping the voltage on the card sometime in the future.
Also, it could be that different vendors have different voltages going through the core or memory, as the PCB is different, sometimes VERY different on some.
apparently not, W1zzard looked at the x1950GT rev 2 and said
the x1950pro cards i have don't have any LM64 chips either, only LM63 :(Quote:
bad news .. no vcore changes possible on x1900 gt rev.2 because ati put lm63 on the card instead of lm64 .. lm63 can not control the volterra vreg
that's why i started looking at hardmods :(
Aw man, that sucks! Oh well, I haven't OCed my HIS yet (already is OCed), but when I do I may keep that in mind. :(
How about a screeny of the setting with tray tool? I am still having issues...Quote:

btw: Unwinder in RivaTuner faq says that overclocking by standart features of CCC and probably WINCLK are pull up ram timings. so this is not right way.
