Back in the saddle with the 2500K

post #1 of 27
Thread Starter 
Hey all, I decided to get back to folding after a long pause and a dead Q6600....

Anyway I haven't changed anything to do with my folding clients and am still running the same parameters as my old q6600...

I am getting between 20000ish and 16000ish PPD (HFM) at 4.9ghz and am thinking this may be a little low.

SO A couple of questions:

1. Would I get better ppd upgrading to client v7?

2. my ram (16gb) is at 1333 7-7-7-something....will i see an increase in ppd by upping my ram mhz at the cost of timings running windows smp?

thanks for the help.

PPD looks about right I think, maybe a tiny bit low. Are you using the computer for anything else during the day?

Are you willing to setup linux in VMware (guides available) folding bigadv you could get >39,000 PPD on a 6901 and >52,000 PPD on a 6903. Those are the PPD numbers I get with my 2500K at 4.7.

On your actual two questions Im not 100% sure so Ill leave those to someone else.

I have not noticed an increase when I tested the v7 client. Your results may vary but dont expect much more than a thousand or to difference at best. The work untis are going to make a bigger difference. On my 2500k i am clocked at 4.7 and I see between 13-26K depending on the WU and how much i am using the computer.

I dont think the ram speed makes that much of a difference for smp WUs. I know it makes a sizable difference for bigadv though. As for doing the whole VMware thing after they shortened the deadlines I think a lot of people stopped doing it. Unless you rarely use the computer I dont think it will be able to finish in time but I am a little biased against using a VM to fold.

1. Nope, I would look into a VM or just stick with whatever client is working for you currently. Aside from the OS they are run in, the clients are pretty much the same as far as performance goes.

2. Probably but it will be pretty small. I only saw about 1-2K PPD going from 1600MHz CL8 to 2133MHz CL10 so don't expect too much gain from just tweaking the balance of frequency and timings. That said however, the SB CPU architecture does slightly favor a higher frequency over tighter timings for folding.

Between 16-20K PPD seems about right to me for that clock in windows depending on how much the computer is used. It's at least in the ballpark.

I do use this computer for browsing, family, and some gaming type action so A VM / bigadv is probably not going to work for me.

For the time being I will leave this be maybe boost my OC a little more then play with timings as Im only at 1.37-1.4 v core core temps at 57-65c and lots of fan left on my antec 920

Too bad we cant fold on the iGPU too!

There's no reason a VM wouldn't work for that, it wouldn't effect browsing or anything else and for gaming you usually have to pause folding anyway.

Just how tight are the deadlines for bigadv?

I haven't worried about pausing the SMP client as it just scales back to use idle cycles (For the most part).

Since my son often jumps on this machine to play Dirt 2/3, Would it Cause the VM to bork? or would the VM just scale back like the SMP client?

You wouldn't want to run bigbigadv on a 2500k and normal bigadv are too rare to even worry about but you would meet those deadlines just fine the once in a blue moon you got them, but you may as well just not even enable bigadv and just run normal SMP. The main benefit of the VM isn't that you would be folding different WUs, it would be that whatever WUs you do fold would be folding faster than in windows. Gaming while folding in the VM wouldn't bork the VM but it may lag the game depending on how much CPU the game requires, for example I wouldn't want to play BF3 while CPU folding but any source game or similar would be fine. The difference in terms of gaming while folding in the VM is that the standard windows folding client sets a core priority of low in task manager while the VM runs at normal, but if that becomes a problem then you can just manually set it once lower when you start it and it will keep that setting until the next time the VM starts (so it WILL carry over through different WUs)

This should get you set up with a VM if you'd like to try it, post back here if you need any further help.

This is the guide for a Linux VM that I use and recommend, it's very easy to follow. First you will want to go into your BIOS and enable virtualization, this should be in the advanced tab of your BIOS under "CPU configuration" it will be called "Intel Virtualization Technology" and look like this, switch that to enable and then press F10 to save the change and exit. Then you just follow the guide as normal until you get to the web configuration part of the guide. At this point we want to make a few changes from the "base set of options" shown on the screenshot in the guide. Right click and open my screenshot at the bottom of this post in a new tab to see full size the settings appropriate for you. You want those exact settings except for putting in your own folding name and passkey, leave the primary DNS I blacked out to it's default. Once you have those settings and hit submit your VM will reboot and then start folding. To monitor it's progress the monitoring program HFM is recommended, to set it up to monitor your VM follow step 7 of the guide but just replace the log folder address with the one shown in your VM window.

If I do go to a VM , would I up my core count the to simulate a 2600k? Would I get a bonus to PPD like the 2600k on SMP?

If so where do the benefits stop? is 12 or 16 threads any benefit or is the pipeline saturated at 8?

Do I bother to flag bigadv?

No you would just set 4 cores for your 2500k, and the benefit isn't in setting more cores or pretending to be a 2600k or something (so no you wouldn't get 2600k like PPD, you would get about 110% of what you get now). The benefit of running the folding in the VM of linux is that linux is just an all around better OS for folding, less bloated, more direct access from the folding to the hardware, etc.
