What RAC should I have?

[Dooms101]

Hey guys, I am still new to Rosetta and I was wondering what RAC I should have for my rig. I have a 1090T @ 4.1Ghz (I like to run a little slower while folding) and it's been folding fairly non-stop for about a week. It seems like my RAC all the sudden topped out at 645. It was climbing at 100 - 200 each day and then it just stopped rising. I had to get new WU's yesterday because the ones I was on weren't working I guess.

[PenguinsPal]

RAC 1,120.26
Total points 23,876
PC Genuine Intel Intel(R) Core(TM) i3 CPU 550 @ 3.20GHz [Family 6 Model 37 Stepping 5] Microsoft Windows 7
Ultimate x64 Edition, (06.01.7600.00)
And its still climbing, been running since Feb 21.... Also a slight OC @ 3.84

[psionic98]

a 1090 @ 4 or greater should still be putting out about 4.5K RAC when leveled out. I could be a little high, but I don't think I'm very far off. If this is the only project assigned under BOINC and its crunching 24/7 I think that's ballpark figures.

My i7 x58 @ 4GHz is putting out like 4.8k itself.

[Dooms101]

It's the only project running, only program running, runs 24/7, and keeps the cpu @ 100%. I don't understand why it is still stuck at 645.6 for 2 days or so.

Maybe it is from yesterday when the WU's were messing up and I had them running most of the day until I noticed they weren't even loading the cpu to 5%, so I reset Rosetta and I bet I haven't submitted WU's yet. I'll wait another day and it'll probably go back up.

[PenguinsPal]

It take 2 to 3 WEEKS for your RAC to level out ... Just be patient ....

[4GHZ_or_bust]

Mine is a hair under 3k daily and only because I've set BOINC to use 5 out of 6 cores (cpu at 83%) and once in a while I completely stop BOINC to free up CPU for other CPU intensive tasks. 4k+ a day is possible with CPU at 100% and no other downtime.

Well for some reason, it just went down to 570, but I think that is just consequence of reseting, hopefully it starts going back up again.

[Dooms101]

Well looks like me and Rosetta are getting along together finally, I am up to 950, and it seems like a jump in 150 a day until I top out around 4K will be likely.

[baditude_df]

Yeah, I'm on the way back up too. I didn't do anything other than grin and bear it for a while. Reloaded BOINC and reset the project a couple of times, but that didn't help things at all. Not sure why, but my machine did not get along with whatever WU's it was crunching.

[PenguinsPal]

Most of my problems are beginning to straighten out too, I think I have a bad PS on that P D 915, other than that everything else is crunching at full speed ahead :-)

[Dooms101]

Well Rosetta was updating the servers the last few days I think, so that's probably why the WU's were like they were.

[Wayward_Son]

My 1090T @ 4.0 24/7 was approaching 4400 before my problems started a couple weeks ago. I've gotten everything straightened out and my RAC is increasing again. If you were at 4.1 24/7 I think you could expect 4400-4600.

Well its been steadily climbing the last few days, it's now at ~1800, should be maxed out in a week or two. xD

[Wayward_Son]

I found that it takes much longer than a few weeks to max out your RAC. For both my rigs, it was closer to six weeks. I found that they had their greatest increase in RAC in the first week, slightly diminished in the second week, slightly diminished again in the third week (but still steadily climbing), and then hitting some kind of plateau in the fourth week. The fourth week is really frustrating because it looks liek your RAC is starting to decrease. Then, fifth week, another solid jump in RAC followed by another plateau followed by a slight increase in week 6 followed by another plateau. Then all my shiate went haywire and I'm only now recovering. In my experience, you will achieve your highest RAC in weeks five or six, at which point it will vary day to day by +/- 100 RAC.

Thanks! I didn't see much info about this, now I'll know what to look for. I put in a new PSU yesterday so it was down for a few hours, and I put a different oc on it then last time so it BSOD'd while I was asleep and lost me tons of hours. It seems to be running great now though, not a problem yet.

[PenguinsPal]

Shouldn't we do something like:
Core i3-550@3.84|20 days|1498.01RAC
C2D 6400@2.13 |20 days|350.01RAC

To kinda get an idea what RAC different CPU's are getting?
I would kinda like to know these things, especially when I am considering a new PC and kinda want to get the best bang for my buck.
For right around $320, I can get a Motherboard, 1090T, or 2120, or 970BE, or i5-650. What would get me the most RAC? :-)
I was leaning toward the 1090T for the six cores but if the 2120 is more efficient with 2+2ht and gets me the same or more RAC I might go that way. I just bought the 550 2 days before SB came out and I already know I bought into dead tech.

[Wayward_Son]

I don't know about the 2120, but the 1090T will destroy the 970 or the 650 in terms of RAC.

[muddocktor]

650, yes; 970 (or any overclocked Neha), no. My 930 has gotten to at least the level W_S has seen on his 1090T when it wasn't being interrupted with heatsink testing and my 875k is around 4750 right now. So roughly comparable are the i7 and an AMD hex core. And the hex core Intels rule them all.

[Wayward_Son]

Sorry for the confusion, Mudd. When I said "970", I was specifically referring to the AMD 970BE that PenguinsPal mentioned. An overclocked Intel i7 970 does beat an overclocked AMD 1090T or 1100T by a few hundred RAC from what I've seen.

[Dooms101]

Well I'd expect my 1090T to beat any AMD chip around except for Opty's and a higher clocked 1090T/1100T.

I was running 4.2Ghz (255 x16.5) for my 24/7, but after I swapped my PSU I've been running at 4.1Ghz (248 x16.5) with lower voltages for better temps. I was wondering if 100Mhz really makes any difference?

[Wayward_Son]

The only AMD chips that were higher than my ~4350 RAC 1090T before my troubles began about two weeks ago (which at that time my 1090T was the highest-ranked single-physical-processor AMD chip on the entire Rosetta project) were Opteron server chips with multiple physical processors on a motherboard capable of supporting two or for CPUs. It was taking 12-24 Opteron cores to beat my 6 1090T cores @ 4.0 ghz.

Anything special about your setup? Like do you have a slimmed OS? I have made a few slimmed Win7's and XP's for when I have time to bench, but I use a OEM Win7 Ultimate x64 build for normal use. This is my main computer, so I have to use it quiet a bit, but Rosetta still runs nearly 100% while I use it and it stays on 24/7. I think I just need to be more patient. Folding is like a marathon and I am used to sprinting in benchmarks :sn:

[Wayward_Son]

Nope. Just a straightforward Win7 Pro x64 install on an OCZ Vertex II SSD. I haven't pared down the OS in any way.

[4GHZ_or_bust]

Shouldn't we do something like:
Core i3-550@3.84|20 days|1498.01RAC
C2D 6400@2.13 |20 days|350.01RAC

That'd be nice but there are variables like how often the computer gets used, did it have 24/7 uptime without anything slowing, etc.


For right around $320, I can get a Motherboard, 1090T, or 2120, or 970BE, or i5-650. What would get me the most RAC? :-)

I have 1090t and it runs about the same RAC as i5 750. Mind you 750 has 4 cores while 650 (all i5 6xx series and all of i3 as well) has only 2, plus hyperthreading isn't of much use in these case due to heavy CPU use so your result will be likely a bit lower than if you went for the 1090t.

[psionic98]

I thought HT improves overall RAC, but only marginally.. like 10-15%

[Bobnova]

It should improve it by 10-30% or so.

[baditude_df]

It should improve it by 10-30% or so.

An i7 920 or 950 D0 with Hyperthreading enabled and crunching 100% 24/7 will yield significant improvements over just crunching with the native cores in my experience. I would say bob is pretty much on the money with a ~20-30%. You should see 4K+ RAC out of either processor.

[psionic98]

my 920 at 4GHz is about 4.5k with HT on.. not sure what it would be w/o

[PenguinsPal]

My i3-550 is running 1500 and still climbing. I don't think that is so bad with 2+2ht. I did settle on the 1090 mostly because of cost over an 1100 with marginal oc ... To me the 1100 is just not worth the extra $30.. The only SB I could afford with the motherboard was the i3-2120. I am pretty sure the 1090 will be a bit higher in RAC the the 2120...

[psionic98]

I think we all just need more disposable income so we can all buy sr2 farms!

[PenguinsPal]

I'll second that!!!!!

Right now I would settle on a job :rofl:

[baditude_df]

my 920 at 4GHz is about 4.5k with HT on.. not sure what it would be w/o

3.6-3.9K. About the same as my old Q9550 at 3.82GHz, with 12mb cache and 4GB of RAM.

My 950 topped 5K briefly after I cranked it up to 4.2GHz with HT enabled. It was mid spring though, and my room started to get a bit too hot so I had to idle it back to 4GHz after that.

[Dooms101]

Well as of this post I am up to 2.4k, and it seems to be increasing about 250 - 400 a day. Shouldn't be long before it's up to 4.5k or so.

[PenguinsPal]

Someone is going to have to teach me how to OC this 1090..... Not like the old days. I'm looking at this Athlon 64 X2 3800+ trying to figure out how, but I am totally lost ....lol

[Wayward_Son]

There is a lot in common with the overclocking of the 939 days, but there are a few new things to keep in mind, namely that your HyperTransport runs a lot faster and there is now a CPU-NB to factor into the equation.

You absolutely need to dive into Dolk's Phenom guide.

Read Dolk's guide (link in my sig), it'll give you everything you need to know. I know you'll have a ton of fun oc'ing Thuban, it's almost too easy ;)

[PenguinsPal]

Will read that. Looks like Rosetta don't like me anymore. The stats removed me the the RAC list... I can find myself by total points, but RAC place is gone .... lmao.... I should be #20 :-(

*POOF* I'm back.....:rofl:

[psionic98]

I'm sure to get bumped out by you guys with better farms, but I've done pretty well holding within the top 10 RAC with my sissy farm of 939s!

And DJCorpse is holding a commanding 50 RAC lead if we went PC vs PC for his 930 vs my 920!

[4GHZ_or_bust]

I think we all just need more disposable income so we can all buy sr2 farms!

Almost had something like that. I was planning on octo i5 2500k farm :comp:

but I got hit with a $3400 bill for something more important than inflating my epeen... er my credits.

[psionic98]

yeah me too.. its called wife and kids.. price is ever increasing!

[PenguinsPal]

It was like pulling teeth to convince the wife for me to get this 1090 that's coming tomorrow .... How do you finesse another PC when you have 6 crunching away on your kitchen table ...:rofl:
