Interesting Observations

post #1 of 11
Thread Starter 
Hi to all,

So the Used EVGA 780 folding card died. Actually one of the fans quit, and forced the card to slow down. This rig was also Windows XP SP3, 32bit.
I purchased a New EVGA 970 4GB from Amazon. Can't let you guys down, ya know! wink.gif First a little history.

I have 2 Folding rigs -
1) Windows 7 32bit - Gigabyte P35 motherboard, Q6700 CPU, 3GB memory, and new EVGA 970 with the 347.25 drivers (Feb 10, 2015) WHQL Approved.
I know the system is old, but I have spare parts. Everything is STOCK right now. I'll experiment later with Overclocking the video card.
I had trouble with Stanford wanting to use the CPU to fold. BAD idea! That was solved - Thanks Dman!

2) Windows 7 64bit - Asus P6T SE motherboard, i7 975 Extreme, 6GB memory, and "the" new EVGA 970 video card with 355.82 drivers (Aug 31, 2015) WHQL Approved
Again, everything is STOCK right now. This was the rig with the Windows XP 32bit system. A new hard drive was installed, and Windows 7 64bit loaded onto it.

I had 2 - Windows 7 disks, and did not want to upset the EULA rules. So 1 rig went 32bit and the other 64bit.

My observations over the past 30 days on System 1, and 30 hours on System 2:

System 1: The video card folds at roughly 240,000ppd. Plus or minus 3,000ppd depending on the work unit (WU).
The CPU runs at about 35% capacity according to the Windows Task Manager and uses 2.1 to 2.4GB of memory.
Speedfan indicates 60-65degF on the Video card temperatures, and everything else is cool and quiet. BTW - this rig is a basement dweller.

System2: The video card folds at roughly 290,000ppd. Plus or minus 5,000ppd, again according to the WU being folded.
The CPU runs at about 15% capacity using Windows Task Manager, and uses 2.14 to 2.4GB of memory.
Speedfan indicates 60-65degF on the video card temperatures. This rig resides in the second floor home office near an A/C duct. Or an open window during winter. wink.gif

Points being seen:

1) System 2 is folding Faster by 18%. This COULD be the drivers, Operating system - Windows 7 64bit vs 32bit, or the CPU.
a) I don't think it's the CPU, and here's why. The older Q6700 is NOT running hot and not being tasked to 100%.
However, with that said, the i7 is 30-50% faster according to Toms Hardware And that is observable on my 2 rigs.
b) The 347.52 drivers vs the 355.82 drivers. Maybe there is a difference here. Not sure. I loaded both from here: Geforce
c) A 64bit system vs a 32Bit system. There have been many discussions and tests (on the internet) showing a 64bit system is faster. I think this is the REAL difference.

2) Windows XP of ANY denomination (32bit or 64bit, SP2 or SP3) WILL NOT handle the newer 970 and up video cards. There are no drivers for this combo.
There are drivers for Windows XP and the 950 or 960 video cards, but not 970 or 980. This maybe a mute point, but for those still using Windows XP, be aware. Upgrade time is coming.
This forced me to load a clean install of Windows 7 64bit to fold on the newer rig. I'll have to move my important stuff over to that rig later. Right now, it only folds!

3) At STOCK settings, the temperatures of both systems and video cards are the same. The memory usage is also the same. Albeit, the 32bit system is using 70-80% of its memory.
The 64bit system is using about 40% of its memory.

4) Wattage at the plug, according to my Kill A Watt meter - System 1 - 282W ---- System2 - 298W I attribute this to the additional 5 fans in the HAF 932 case.
In addition, the Q6700 draws 105W at idle vs 130W at idle for the i7. And the i7 is working approx 40% easier than the Q6700.
And who knows, at the time I took the readings, things may have changed a bit in the rigs with amperage draw on the motherboard, memory, CPU, GPU, etc. A 6% change is within margins.
I took the reading over a 5 minute time frame for both once the systems stabilized after 15 minutes of running. Stanford probably did not like that!
Each fluctuated about 2 watts, so I gave a middle of the road reading between high and low.

5) Both folding rigs are at Maximum folding power as presented by the Configuration window provided by Stanford.

If you are still with me, Thanks. Just thought I'd share some info on my folding rigs, so that others may learn and see what they are getting into.
Folding is fun, BUT very, very addictive!!! thumb.gif
Maybe, I'll get back into the Top 20 folders for OCN soon. Who knows? I remember that was a BIG deal for me back in 2006.

BTW - Enterprise1701 - I'm coming for you tongue.gif

Feel free to ask or post any questions or additional comments.

I would say the main factors are different driver version (this can make a huge difference), and one thing you didn't mention, the i7 system has pcie 2.0 and the other doesn't. Also 64bit vs 32bit probably affects it aswell.

Can you check the effect of 32bit vs 64? I think this would be interesting to know.
Do not fold on CPU's.
Run same drivers on both cards.
Run same clock speeds.


Evaluate after about a week of folding.

Maybe you can run this by one of the folding mods and see if you can have this data updated on the TC stats page - If so, then you will need different passkeys for each GPU

I can certainly update the current 347.52 driver to the newer 355.82.
That might show the difference you are looking for.

I'll do that this Sunday, in the early morning, after this weeks totals are calculated.
Then let it roll for a week...

I'll write back here.

I think this test would be flawed because of the significant difference in hardware configs between your two setups.

Agreed. I have little knowledge of the above systems.
I would still run the test, at least you will know which driver works best on #1 system. thumb.gif
post #7 of 11

I can put it in, there is no issue with that, the only issue would be the fact that I think the CPU plays a larger part than you think. Overclocking a CPU to 4GHz+ can improve PPD quite a bit.

Hi lanofsong,

BigBlock is absolutely correct. I found this on our site: Overclock.net

PCIe 1.0 vs PCIe 2.0 = twice the bandwidth. So it would not be a good comparison. BUT, I'm thinking about something else.

You are absolutely correct!! thumb.gif

So there are several differences:

1) The PCIe slot and the bandwidth difference.
2) Operating systems - 64bit vs 32bit
3) The drivers - 347.53 vs 355.82
4) CPU clock speed - Q6700 (2.67) vs i7 975EE (3.34)

Two of those differences I did not take into account. So newer Motherboards, with 8GB of memory, higher clocked CPU's, and PCI3 3.0 would be great folders.

Gets me thinking of another comparison possibility with my current equipment. rolleyes.gif

Hi Dman811,

You are good! thumb.gif Quick on the responses, and great insight too. I'd give you a rep+, but that has been disabled. And that's too bad.

No need to put this any where. Not sure of the helpfulness. Most people (75%) are using much newer motherboards and CPU's, with Windows 64bit systems.

With that said, I do have several Gigabyte P35 motherboards laying around, and 3 old Q6600 CPU's. They could be easily overclocked to 3.0Ghz along with the Q6700, and THEN a system loaded with Windows 64bit to compare apples to apples. 64bit vs 32bit...

Would that be of any use?

And based on your comments. I might have the push the Q6700 a little harder. That system is quite content right now at 240,000ppd per the config screen. Not sure what it "actually" is.

Let me know
