Q - are the 3GB 660TI's acceptable for Pro cup.. or is there a 2GB limitation for onboard memory?

looks like the IC for GPUv is one of the 2x located on the back side just above your vendor sticker.. what are the IC #'s there?

Ahh.. mine is QE6V.. so guess my cpu is newer than those batch.

if you dont mind - which vendor mobo was it tested on.. and how much vccin?

I have an early CO ES.. no death here and been testing since Dec'12 with it. *Only deaths I have heard of were early C0 Malay retail.. seems vccin over 2.3v is 'scary' for them. Though between folks trying to shove 1.6vcore while leaving vccin @ 1.85v, and people not using a DMM to verify SA and Ring/Uncore.. i can see why some CPU have gone to heaven **MSI has actually adjusted the 'safe' voltage ranges in the BIOS since retail release to prevent people from getting to friendly with certain voltage ranges on air.

MSI is trolling with 'ES' volts **funny, uncore volts are listed but not vccin.. these guys

ATI Tray tools works with Volterra IC's as well for voltage set..

PCI-E link 'cold slow' .. strange.. sometimes I get it.. other times not. Could be tied to input voltage ratio's. I have had both: VGA signal 'drop' to black screen, and VGA/PCI-E cold slow.. but adjusted Input and IO's and have not had it return.. yet

I have some results on air using the Mpower Max and the Xpower, as well as some pics in my thread on OCN http://www.overclock.net/t/1396921/msi-z87-thread-xpower-mpower-max-bios-screens-and-info/0_40

go l0ud, or go home!

RT = switching frequency *will test and post some resistances and volt levels with ocp mod. A few caps seem to be helping. L0ud posted some good results with the card so far. Thanks for the info

@ zzolio - what is your +12v input reading at under load - as measured at the PCI-E input? *nice job on the mods btw! I will be modding the same, except without VID [do not think VID benefits this design, by moving OCP/ILIM as VID increases]. You mentioned you are getting OCP still .. or not?

GPUv confirmed on NCP flavor as well.. same pinout, just different packaging/rev#. *Need ILIM and RT *Need functional cold-slow now too!

I see the Marksman is getting use at your place after all! Nice result with first CPU

tfresh isnt over 9k

...Would be nice to see DS to work mods for OCP, OVP and RT.. anyone care to post a snippet? I will post resistance and mod points once confirmed.

bring teh moddz!

@ Mikecdm - Thats one crazy overvolt for sure! The Mpower I have, only has ~+.15v on CPU and vDIMM, running 100% droop options, with 2x Switching Freq.. which is very tolerable. *You using the Aux power connection on the board by chance?

more info for mods on the IC here-> http://www.overclock.net/t/1009397/msi-6950-tfiii-pe-oc-testing-w-cl3p20/40_40#post_14394941 ..its same IC as 6950 PE/OC and GTX570 PE/OC.. http://www.overclock.net/t/1203434/msi-gtx570-tfiii-pe-hardmod/0_40#post_16342483 **Per Ch. OCP and total OCP brought solid gains to both 6950 and 570.. seems circuits were a bit current limited even at stock clocks. Make sure your PCB does not have current shunts though.. as these will require additional mods to surpass amperage limitations.

yeah, needed the boost.. good stuff man.

@ XA - could be just your board too.. seen some interesting variations in characteristics just using 1x Mpower over another.. *I bring vcore over ~1.87v in the OS though.. and not in BIOS, as cold booting high-vcore has been where I have seen catastrophic failure with them. vDroop starts getting increasingly worse as you tip 1.9v.

Use PLL for help with cold slow.. doesnt really do much else, lol. *cant wait to peek at some cold results with mods.

solder it up Bull ! Dont let manufacturer limitations get in your way!

.. i been saying.. *the mods are the same as the GTX570 PE/OC.. full OCP, per phase OCP, GPUv and RT should all be the same.. I would recommend PLL and vmem of course for LN. http://shrani.si/f/2h/Rg/2Hcb3VK5/img2987.jpg http://www.overclock.net/t/1203434/msi-gtx570-tfiii-pe-hardmod/80_40

only another 100mhz now..
