GTX4xx/GPU3 thread, post results and OCs here

[ThunderRd]

I am hoping that we'll see a few more of these GTX 4xx cards on our team soon, so why not have a thread where we can discuss GPU3 folding?

================================================== ============================================

I've been experimenting to see how overclockable this Gigabyte GTX470 is, and it's been easy so far.

Overnight I got the shaders and the linked core (one can't be pushed without the other) to 721/1442. That's very, very close to the 480's 725/1450. It will go more. I also lowered stock voltage from 950mv to 925mv. It has been stable so far. With the fan at 75%, temps at these levels didn't exceed 69C. That's good, according to all reports.

I'll leave it here for a day or two to make sure it's stable, then see how much further it'll go. I think it's quite impressive that I was able to drop the voltage as well as go to a 20% overclock on the shaders/core. Makes me curious as to how much less voltage it really needs before crapping out. I may try that, then see how much headroom I've got and make some decisions where to leave it.

Screams out for water, though. The fan is noisy after 75%... guess that's my next project. From what I can see, there's too much headroom here not to go with water eventually.

Frame times on GPU3 WUs is down to 38 seconds from 47 at stock settings.

[ThunderRd]

OK, so I've been playing around with this card and the voltages for a couple of days now, and here's what I've found.

Stock is: 607 core/1214 shaders/1674 mem
[Stock for GTX480 is 701/1402/924@1.1V]

Using OCCT, Kombustor, and the GPU3 folding client as stressors:

Stable to: 721/1442/1674 at stock voltage, 950mV. 74C fully loaded.

After 721 core I had to bump the voltage to stay stable.

740 required 962mV. 750 needed 975mV, etc.

My best OC, staying stable on all tests and under 80C was:

Core-800/Shaders-1600/Memory-1750 @ 1.050V That is a 32% overclock with a .1V increase, keeping it well within voltage spec.

All I can say is- Wow. I have no idea how much further it would go on water, but I limited myself to 80C, so there is still quite a bit of headroom there with better cooling. Frame times have gone to 35 seconds, ppd for folding is just over 15,000. I suppose I will be forced to do some benchmarking now

got an MSI N460GTX Cyclone SC. stock clocks are,
core=728MHz
shader=1456MHz
memory=1800MHz
core V=.987mV
temp-48c
fan-61%
F@H=9400ppd

I didn't leave it there long and now,
core-750MHz
shader=1500Mhz
mem-1800MHz
coreV=.987mV
temp=48c
fan=61%
F@H=9600ppd

both F@H numbrts are quite close to the GTX 285 FTW @ default settings,
core=702MHz
shader=1584MHz
mem=323MHZ
coreV=1.22mV
temp=81c
fan=80%
F@H=9800ppd

haven't spent much time tweaking it yet. small increases in OC yield small increases in ppd.

I'll just have to step on it a little more today.

GtX460 now @ 775 core/ 1550 shader/ 1800 mem(stock)/ 1.025v(+.05) 46c and 9900ppd

so far there is no need to water cool this card. doesn't mean I won't.

right now there seems to be no end to the OC on this card. I know I'll find it sooner than later. the full .1v increase that TR used on his GTX470 is in the works. it is keeping pace with a stock 285GTX but much, much cooler and less power too!

Lots of headroom on these Fermis with water, I'm sure. I'm waiting for the block prices to come down a bit before buying one, though.

[dabaerman]

$110.00 for the 460 block. $115.00 for the pump/res. another $100.00 for rad/fans/fittings.

after upping the voltage .05, the core/shader to 775/1550, the temp never went up! the fan @ 61% is quieter than the cpu cooler (stock AMD).

Got my PNY 465 XLR working on folding
1 gig ram
256 bit bus
Stock right now

Core 607
Shader 1215
Mem 1603

how do i find ppd? been awhile since i folded

[ThunderRd]

Use a prog called hfm.net

Just do a google for it, I don't know the address offhand.

I'll guess you can do 10k ppd per card, or something like that. Crank 'em up.

Report.

[Necorum]

Ppd 10152 for just one 465

Added the phenom II x4 to the mix and found out i needed - smp 4 was wondering why 25% was being used lol

LOL sometimes I make pretty good guesses

So 2 of them + SMP on a quad will give you somewhere in the neighborhood of 25K if you run 24 hours. Even if you don't, you will see some good results.

[Necorum]

i should be able to climb the ladder a bit with that

Hows your 470 fold/game at the same time

5100 ppd - phenom 2 x4 965

Man this case and current setup full load not in air conditioning / is nice and cool compared to my old setup idle in air conditioning. My new setup full load cpu 56c , gpu 88c - old setup idle 75-80c idle gpu and cpu was idle around 50c

Just bought 2 GTS450s, EVGA 01G-P3-1450-TR

950/1903/1501 which nets just under 7.8k PPD. Bought the cards at $80 AMIR, feels like a good investment.

Only one card is up now (team 32), when I get the other up it iwill be team 45

Where have you been cw? You have been missed 'round here.

Well, the easiest explanation, I've been a senior member (now moderator) at ocf for years, in fact, so long ago that Daniel actually promoted me to senior member (ocf), so that's where I spend most of my time.

Money has been tight so hadn't been folding, but got a good deal on the GTS450s and money has been a little better lately so I hope to stay at it.

Should see at least 7.7k PPD from me, hoping to add another (2) GTS450s or maybe GTX460s here in Jan/Feb

[dabaerman]

the GTX460 has been folding along @ 810 core, +.05v, on air. 10.7K/day.

best of all, I got the half dead 295 folding again and so far it's @ 100% and 12.9K/day.


Ron

[ThunderRd]

That's all good news . We need all the help we can get.

Looks like we've lost SteveI. Has anyone been in touch with him? I wonder if he's got some folding problems.

[dabaerman]

darn, the half dead 295 is just half alive and folding. one of the gpu's is so bad that it wont complete a wu.

can only speculate that SteveI has been a very busy man and his family/job/business require his undivided attention.


Ron

[ThunderRd]

Maybe it's time to try the baking job on that GPU, Ron. I'd love to see if one of us can resurrect a card that way.
