Bugged Nature when using RICK tweak.

[Holst]

Hi all.

Ive been benching today using the tweak RICK/PEDRO descovered.
I now have some concerns over this tweak.

It does seem to have given a performance boost in all tests but I could NOT get a run with the graphics overclocked where my nature score was not bugged.

This run should have been 25.5k max, but with bugged nature of 219fps it gives me a false score of 26590...

Problem was that even though I ran nature ten times over the result was the same bugged score every time.. appart from when I dropped back to stock graphics clocks when I got a "normall" score.

This is worrying because if I can get this sort of repeatability, others may also have bugged natures and might not notice... Id recomend that everybody checks there nature to make sure that its not artificially high..

I am NOT saying that everbody has a bugged score, as all my other tests did fun faster with this tweak. But its worth checking for as I can repeat the bugged nature over and over...
I havent checked anybody elses scores, but if you do have any odd ones can you post here.

Or if you think this is down to something else on my system let me know.
I never had this problem before switching to multiprocessor driver.

Thanks.

Hi Holst,

Interesting possible side effect.

I noticed one too, my cpu tends to run at 35-40C normally but after the Ricky tweak it was saying 55C in MSI Core Centre. I have not had time to double check or confirm yet it is not something co-incidental though.

Haven't seen the problem on X800 series cards atleast. but then again I'm not running a multiprocessor driver on a non-multiprocessor CPU (A64 that is)


nature remained at 201-203 w/ ES X800PRO 12pipe 472/499, and 262-265 on X800XT PE depending on driver and mobo used.

I think that might be a genuine increase in temp.

My system needed the fan speed turning up and more Vcore to run at the same speeds with this tweak enabled.
Heatsink felt hotter after doing this tweak, probably due to ACPI being messed with...

Yes it throws on a lot of heat for some reason.
In fact, my temps actually cool off under a load compared to idle temps
Thats right, if you want cooler temps just put a load on the cpu, strange

And on topic, I havn't seen any nature problems with the X800 cards.

I noticed the same, my roomtemp is quite hot but still I have lower load temp then before

[eshbach]

i noticed my load temp was 1-2 degrees less than normal, but i never see idle temps because of folding...

I dont know how hard your pushing your card but I know if you push it to hard it can lead to a bogus nature score. Bowman noticed that a long time ago. I got my 9800pro to do it once.

Hi,

I've succefully done the tweak and have been trying to explain to a friend what this tweak does exactly, but I'm ashamed to say I have no idea what is going on that causes the increase in scores/performance.... could somoene outline exactly how this tweak boosts performance please?

[sky]

well for me it basically upped the general score abit - though with 2k1 my 9800xt @default scored higher in all tests but nature compared to the 6800gt i run now (xpm2600, ...) . anyway my idle temps went from 35°C to 42°-43°C. full load does nothing to that temp - it stays right there, maybe constant 43°C - load has been ~40°C before. pretty strange imo.

could somene pelase tell me what that tweak is all about?

I cant test this tweak with 3DMark (no vid card worth using), but with SuperPi and Pifast my CPU was about 4 deg hotter (measured from evap temp) with Multproc ACPI vs Uniproc ACPI.

[rick_fx]

I used to have 36C idle. Now it's around 54C.

I installed CPU Idle, now back down to 36.

[sky]

if i'm not completely mistaken all cpu-idle does is enable the cpu-disconnect function (stopgrnt, halt) - and you could do just that via the bios, though it might make your overclock a little unstable. don't know if this is still the same for a64's and fx's but it is like that on xp's...

[Holst]

I think my instability was caused by increased temperatures.
I only have rubbish aircooling at the moment.

I dont like using CPU-disconect as it caused instability for me in the past.

[eshbach]

one more word of caution...

i tried udoing this tweak, and, well...

windows is now reinstalling.

Thanks for the tip.

I VERY nearly tried to switch it back. I dont think ill bother now.

I haven't had any real difference with my 6800 NU benchmarking with or without this tweak.

for me, it only gave about 150 points extra.
it's a interesting tweak, but did little for me.
no real difference in my nature scores.

That is not strange at all, that is a direct effect on the change in the OS ACPI layer (in more current terms is like the idle process never turrn on / the halt instructions act differently on the cpu cycles and the performance is boosted) ..but no pain no gain ..or in this case - "no heat no gain"

Enjoy the tweak
I wish I have the money to buy an FX-55 tomorow (it is very dificult to selll the FX-53 WR breaker here in Portugal ) - but we going to try to chatch you with my "old" FX-53, that is much sportive and fun ..
For me and Ricky, the most important is to have fun, and of course it is quite fun and challenging to barriers with less resources
Now if you you please e-mail us some ethylene ASAP, we will be very grateful

BTW on topic - it is very unlikely that this change will cause some effect on the graphics card, altought some components on motherboard may have the temperatures raised a little (or a lot in some mobos).
If you are running on air or WC or even standard phase-change that can bring instability to the system - so I advise you all to not run 24/7 with this ..

When benching at sub -100ºC it is not a big issue (all components drop temperatures dramatically and a lot insulation skills are required) but cascades are not mainstream... yet ...

so once you do the tweak, you cant undo it without messing up windows and needing a reinstall? is it possible to do the tweak wrong and need a time consuming reinstall? I never heard of the tweak bugging any scores, I think your bugged nature is cause your gpu is artifacting and giving errors which skew natures fps. try clocking your card down a little and run nature again. the fact its normal at stock means its the gpu, not the tweak

[CodeRed]

You can undo this tweak

I cycled between all of the different HAL drivers, and then back to the original Uniproc one without any troubles at all.

Wow this config change really cranks out the heat as Zakelwe & Opp said. My evap went from -52 idle @272x12 to -42 @250x11, so for me at least this is a useless tweak without better cooling.
