I've been looking at the credit granted to my Phenom 9850 and it seemed rather low to me. I had a look through other computers and found another 9850 that was getting much more granted credit per unit than me.

As you can see, I'm requesting more credit than I'm getting and even that which I'm getting is low in comparison. How come it's so low? :(

Could it be my client version? Nothing runs on that PC other than BOINC.
Could it be the RAM?

Most obviously the difference between you and the other guy is that you have a 2Mb machine running XPSP3 and the other guy has an 8Mb machine running Vista64SP1, though your floating point speed is much higher for some reason which should work to your benefit, I'd have thought.

Is RAM such a major determinant of granted credit then? If so, I'll have to think about that myself! I'd always run the latest recommended Boinc client as well, though it surely can't affected the granted credit very much, if at all.

Now that you mention it, none of my XP 32-bit boxes are getting quite the right amount of credit for their work although none of them have 4GB of RAM like my main machine.

As far as the RAM goes, no machine has maxed it's RAM usage such that it won't run R@H, not even close. Could it even be the speed of the RAM that makes a large difference?

I've mastered reading, but for technical knowledge you'll have to wait for someone better than me LOL!

I'm just off to check crucial.com to see what this laptop can handle in advance of a response

It's most likely that RAM speed affect R@H more than RAM space (assuming 2GB+)

Well I've done some digging around through various computers and found that the ones claiming credit and then getting less are running the older client, 5.1. My main computer that I use, is running the newest client and I'm getting the right amount of points for that. Guess I'll update and see what happens :)

---

I expect the change will be: you not getting more, but claiming less.

Well updating the client hasn't had any effect. I looked through some more computers within the project and found this one...
https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=426386

Dual core which is slower than mine:
https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=832978

yet getting almost exactly the same RAC. It also has less RAM. I'm at somewhat of a loss as to why I'm not getting as much credit as I think I should be.

I would suggest Sid might have overclocked his to 3.2GHz. Your average granted credit is
around 12.8 and his is 16.5:

2.5GHz / 12.8 * 16.5 = 3.2GHz

But then surely his integer and floating point performance would be higher? Mine is lightly overclocked to 2.8GHz yet I appear to have better performance.

I've looked at your stats and I see you're running a Q6600. I presume you've overclocked it? If so, would you tell me the clock speed and the RAM speed that you're using.

it's 3GHz with 2GB DDR800 (RAM is running at stock).

Hmmm the RAM in my machines is DDR667 and DDR533. The only box I have with 800 is my 940 which is getting the full amount of credit. Might be worth testing for a few units to see if the RAM speed affects the results.

Hmmmm....

So please, see this:

and tell me why always credit granted is lower then credit caimed...???

i'll have a look at that next time i reboot (it won't be for a couple of weeks tho!) as the comp is in use. I would expect the RAM will be much more important with a smaller cache, and will be task-dependent - i.e. some (larger) tasks will be more heavily affected. No idea if the timings will have much of an impact too...

Hi. I am "the other guy"! :)

No overclocking here - stock 2.5Ghz machine (200MHz Bus x 12.5 multiplier).

So I'm running Vista with 8Gb and Boinc 6.4.5 compared to XP with 2Mb running Boinc 5.10.45 - those are the basic differences.

My RAM is DDR2 running at 400MHz - 4 sticks of 2Gb Nanya PC2-6400 (400MHz) 5-5-5-18 according to CPUZ.

My FPU speed is showing 20% lower (OCing probably), but my Integer speed is nearly 20% higher. Something in there? No idea, but it doesn't sound right, does it.

Aside from that, my machine is on 247 but I work away half the week so there's literally nothing else running on it most of the time. I also tweak my start-up programs with MSConfig and the help of Bleeping Computer and my Services with BlackViper - I've found that very useful.

I'll PM nightmareXX with any more detailed information he might need. If I was him I'd be confused too.

Ah hey, thanks for replying :D

If you've looked at my Phenom recently, it'll be showing the speeds at stock. I dropped the OC thinking that it might be affecting the results but it didn't make any difference.

The only continuous feature between all the PC's I've looked at and been able to get in touch with the owner is running PC6400 RAM. I've pinched some from another PC and put that in the 9850 so hopefully that'll make a difference.

As far as that systems load goes, it's running BOINC and nothing else. It's not used what-so-ever so each R@H gets 25% CPU.

hmmmm... maybe the memory speed is quite important then... unless cool n quiet is kicking in to some extent?

Nah, got that disabled and I control the fan speed via speedfan. As far as I'm aware, it'd only kick in when the system is idle, which is most certainly isn't.

I've heard that idle priority tasks can be ignored by some OSs (can't remember if it was windows or linux). If you've got it off then it looks like memory speed is the bottleneck, unless it's down to a difference between the taks the two of you were running.

---

Well I've done a few units with the DDR800 RAM and it doesn't appear to have made any difference. I'm fast running out of ideas now and it's starting to really annoy me :(

are there any other threads running that could be causing rosetta to get swapped out of the cache? Anti-virus maybe (Norton has a reputation of being a bit of a resource hog)...
