That is a ridiculous number of RAM chips! Imagine a modern card with that many chips. That would be like 32GB on a 6800XT.
Right? Honestly, I'm extremely thankful those pads were okay, that's gotta be painstaking.
Alright, ""quick"" V8600 update!
Above is stock settings in FurMark, it tops out at just about 60.5°C.
All full-system power measurements are readouts from a Kill-A-Watt P3. Case ambient temperature was kept at about 25°C, measured by motherboard's onboard sensor. I used a custom fan profile, as I don't mind the noise and wanted good thermal headroom, and this was kept identical between stock / OC tests. At stock, full-system power consumption was 275-280W during FurMark.
The max stable OC I was able to get, without touching
any voltages whatsoever (so 1.2v constant vcore) was 840MHz core, 1000MHz memory. Anything higher on the core eventually caused a crash in FurMark, and anything higher on the memory resulted in negative scaling. Whereas 840C / 1000M produced near-constant 45FPS FurMark with the above settings, 840C / 1050M produced 43-44FPS. When overclocked, total system power consumption was 300-305W. Max temperature observed was 65°C (not the run above). Unlike newer GPUs, this card absolutely hates to have its clocks changed by >15MHz during FurMark, it completely locks up the system if you do so. However closing / restarting FurMark in between clock changes solves this hurdle. I was very concerned at first when everything locked up going from 688-700MHz core w/ memory untouched.
850C / 1000M is borderline stable - probably benchable, but FurMark eventually crashes after 2 minutes, and performance is still 45FPS. 850C / 950M is stable but worse than 840C / 1000M.
Performance improvement
FurMark: 37FPS -> 45FPS, +21.6%
Unigine Heaven total score: 612 -> 741, +21.1%
Woah! Just look at the difference in minimum FPS, that's a 264% increase!
I cannot overstate how huge this thing is. Seems to be about identical in length to my reference HD5970, to the point where in the P300A I had to mount one of the intake fans on the outside of the case (and even then, the card has to go in at a 45° angle). Also, I had to take out one multiple screws just so it could slide in the PCIe slot... same as with the HD5970. Screwholes circled below (one is DVI nut).
Side note to anyone looking for one of the most cost-effective coolers out there, the Thermalright PA120 in these pics is like $42 on Amazon US and kicks butt. Keeps this 2600k below 70° (typical 65°C) in P95 at my current settings. Here's an impression of the sheer size, it's maybe a few centimeters from the front fan.
Test system specs:
i7-2600k @ 4.5GHz, 1.35v
Kingston HyperX DDR3 2x8GB @ 1866MHz, CL10-11-10-30-243-2T [XMP]
ASUS P8Z68-V Pro / Gen3
MX500 1TB SSD
Seasonic Focus GM-650
Qualcomm-Atheros a/b/g/n add-in card, which adds marginally to power consumption.
...Are there still active ATI threads I can clog up?
I've really become a big posthumous fan; although I don't have all that many ATI cards (yet) I love the ones I do have. BIOS modding is trivial with TPU's fantastic tools and DB, and I've got some fun cards like a HD5970, a couple HD5870's and HD5670's, plus a HD4870x2 on the way. I want to give them some attention and love again
plus I like doing these write-ups, maybe a bit too much... I am so sorry for the length of this
