A7N8X humming along now - better seti WU times!

[Assimilator1]

Setting too low latency timings won't hurt your RAM ,though like you've heard it is possible that it'll corrupt HDD data

My RAM is at 2.5-2-2-6 @178MHz Dl Chl

It's funny but on mine I can't get any fsb boost by setting them higher either, it's like this is just the best setting on this mobo.
Right now I'm setting it 11.5x 180 at night when I'm sleeping and then lowering to 11.5x 177 during the day.
Each 1 mhz fsb seems to equal about 3 minutes off of each WU at this point, so shaving 9 minutes off each WU overnight will definitely add up.

are you sure about that math

then according to your math

if i go from 12.5 x 200 ---> 12 x 208 then my WU times should drop by 3 x 8 = 24 minutes... hmm...

let me try this out

 

[Wiz]

that's just what it equals on my board at these speeds - I think it's a game of diminishing returns at some point.

Between 177 - 180 I get a 9 minute difference on the same AR WU's - doesn't mean I would get the same at 137 - 140 or 197 - 200.

I need to spend more time testing stuff. I changed from 2-2-2-6 to 2-2-2-5 and my aida benchmarks in read and write dropped (meaning they went slower). I am not sure if it would have effected seti much. I am now wondering how much benchmark scores like that will effect seti. I may try to relax my times a touch like 2-3-3-6 to see what that does. I assume that stressing the ram that hard could have a negative effect on it and actually make it slower correct?

 

[Assimilator1]

Yeah if you choose timings that are beyond the RAMs limit then for some odd reason performance drops.

Try 2-2-2-5 upto fastest poss FSB with good benchmarks ,then run SETI
Then try 2.5-2-2-6 upto fastest poss FSB with good benchmarks ,then run SETI
Then try 3-3-3-6 upto fastest poss FSB with good benchmarks ,then run SETI

Highest poss cpu multiplier in each case of course ,then you should be able to find out the best config for SETI

 

[MoFunk]

I am at 2-2-2-6 right now and my average time is about 2:15 I will change tonight back to 2-2-2-5 and see what happens to seti. For me I am trying to look at benchies but seti is waht really matters!

 

[Wiz]

I think seti officially became a benchmark when Toms Hardware Guide (THG) started using it that way

LOL! Thanks Tom!

 

[MoFunk]

Well my other stick of ram arrived today......WU WU WU! Will be running dual DDR now!

 

[Wiz]

Please post the WU times & current settings after you crack a few. I'd like to know if you see any improvement.

 

[MoFunk]

I will. Right now the settings are this
1x512 pc3500 11.5x200@2300mhz 2-2-2-6 2.77v CPU 1.725v
Avg. WU is 2:15 according to setiqueue. I will post specific times for specific ranges when I get home. I hope that I can just slap this stick in and not have to mess with any times. I am also going to try and find the time this weekend to put my iceburg on the northbridge and the zalman on the south. I have another HS that I am going to cut up for the mosfets as well. Hopefully that will get me up and over 200. If I try to go even 201 right now I can only stay in windows about 30 minutes.

 

[MoFunk]

Well my system did not like the dual ddr! I even tried running the ram at befault timings and lowered the FSB to 190. Would crash after 10 minutes. So since I do not want to loose any seti production and am also running the new stick in place of the old to "burn it in" I will play around with it this weekend. This will also give me the chance to put on the other HS and the North and Southbridge cooling.

 

[soni]

Got my RAM RMAed, so with the new stick, HyperX PC3000 @189-2226 I can run 11x189

Ars WU 2h27m9s

 

[MoFunk]

That is a nice WU time. I am not able to run at 190x12 2226 so maybe that ram needed a little burn in time. I will let this run today and will try to up the FSB tomorrow. If I can get back to 200x11.5 I will be very pleased! Once I find my wall I will run that Ars WU.

 

[MoFunk]

Well I changed my HSF to an SK-7 with 80mm fan. Put on the zalman on the southbridge, iceburg on the north and installed my bios savior. I was able to get to 200x11 but not 100% stable with the latest 8RDA bios. Well with the savior I flashed to 3305 and am now at 205x11 I am very happy right now. Seems to be stable but wont know for a while. My cpu temps went down 4c from my Alpha. My memory scores in both sandra and aida went up quite a bit. Will see how seti does. I wont try the ars WU until I find the wall of this system!

 

[Assimilator1]

Should be interesting to see

 

[Shimmishim]

hmmm interesting.... maybe i should get another 512 meg stick and run my board in dcddr as well

wow, 1 gig of ram.... now that's fun...

 

[MoFunk]

CR@P!!! It will not stay at 200 or more! I am now at 195x11.5 so I am not sure what else to try. I guess I could drop more on the mult and see, but I may be stuck without the voltage mod! Oh well. I am burned out for the time being so I am going to let it sit for a while. It really sucks that I technically have a kick arse overclock with air cooling and I can't be happy with it! I a driven to get sub 2 hour WU's. I need therapy! Or maybe water cooling, yea that's it, water cooling............help me........

 

[Assimilator1]

Why not settle with what you've got!:Q

 

[MoFunk]

Well because, um, I do not know why, I just can't! LOL I think it is because I was at 200 and now I am not. LOL I am just a tweak!

 

[MoFunk]

Hello! Why I am posting here again and lot letting this thread die? Well because I have an update! My system evidently does not really like running in dual channel. So I put the ram in slots 2+3 and am now running 2x512 2-2-2-6 220x10.5@2320 1.75v 2.9vdimm Sandra scores are 3328 INT and 3061 float Aida scores are 3294 read and 1251 write. But aside from hoping that this stays stable, the real test is seti! Will keep you posted, in this thread of coarse!

 

[Assimilator1]

220MHz!!!:Q ,that should be awesome at SETI

Keep us posted

 

[MoFunk]

Let's hope! I would love dual though! Maybe it needs the vmod for that. Anyway I looked at my queue this morning and an angle range 0.417 was done in 2:15. Not as great as I had hoped. But what else can I do right? I am going to try and up the FSB again, but I think this one may be a bit to high, I get some program crashes now that I never got before, XP seems stable, but just a few programs seem to freak out a bit. So once I find a happy FSB I will be done. (yeah right )

 

[Wiz]

Well one thing is for sure, you (Mofunk) messing around with yours has cured me - I'll take what I got and crunch on!

 

[MoFunk]

LOL. I do tend to tweak too much don't I! Well I am glad that I could help! I also think that I am done, at least for a while. I am very burned out on trying to lower my times and need to just take a break from it and be happy. I am going to be working on a case mod soon, so I will focus on that for a while.
