TPU's Core i7 Overclocking and Feedback

[Fitseries3]

doesnt like to bench at that clock

 

[kid41212003]

I found I could clock higher with HT off, which i think makes sence to me, now sure if that means it doesn't work properly or that it's more stable rolling with less cores to manage.

When I first got my Core i7 setup, I got some really weird results with my games.

The results were alot better with HT off in Vista even at same clock speed. But there is no different in XP, no matter HT on or off.
At first, I thought it's just because of the buggy Vista thread management.

But it isn't, after I bought this GTX280, I re-ran the all the test with a single card, and I noticed there aren't any different on any OS, except results with SLI enable.

I know I already repeated this many time and you all already got sick of hearing this... But I just couldn't ignore all the results that I spent weeks to run, to find out what's wrong with Hyper Threading.

In case you are too lazy to read the link I just posted.
That guy run 3dmark 2006 on a single gtx295 on Vista and XP, and there are huge different...

i suggest you discuss this in a thread that has that subject as a topic. this is i7 talk and i dont feel like we are on topic any longer.

 

[kid41212003]

It's about Core i7 Hyper Threading and Multi-gpu, HT on vs HT off with higher clock speed...

 

[Fitseries3]

yes but the 295 doesnt do well in 06. thats all im saying. i've got tired of messing with it just to be dissapointed so i gave up.

HT on does seem to impact 06 but not vantage UNTIL you reach high clocks in which heat becomes a problem and HT must be disabled.

thank you for not blowing up like other people may have.

 

[PaulieG]

I honestly haven't done any benching with HT off. What kind of clock differences are you guys seeing b/t HT on/off?

 

[Fitseries3]

i cant bench over 4.2ghz with HT on. HT off ive booted 4.63ghz but didnt get a screenshot.

 

[kid41212003]

Fits, I'm not trying to piss you off. I'm trying to prove my points, because I think it would help you guy with your scores, I don't have GTX295, I don't have to be so persistent about it. And because I'm not even have it, I really can't test it myself, everything I did was trying to get you guy do it...

27k 3dmark 2006 with a single GTX295

Results with GTX295
Link

And I think, that's with HT on and at lower clock speed on Windows XP, you will have better results with 3dmark 2006...

This will be the last time I try to tell you guy my points...

 

[Fitseries3]

xp gets better 06 scores period.

you cannot run quad or tri sli in xp though.... i cant get it to work at least.

 

[kid41212003]

What about Windows 7, is there a driver to support quad or tri sli for it yet? Because SLI worked properly with HT on with Windows 7...

 

[SystemViper]

I think i'll try some single card.... and see where it gets me.

I might just load XP on another drive for s & g's , got to keep an open mind.

 

[Binge]

it was only a 700 point hit to my cpu score.

 

[kid41212003]

Let's me hug you Binge...

 

[Binge]

Still a terrible score

 

[SystemViper]

When you look at the ORB with FM approved drivers my 28606 is 12th on the list...

the 3D06 loves HT off...

 

[mudkip]

Does anyone has the new D0 stepping?

 

[SystemViper]

yea, that 28k posted is with the new "DO"

 

[Chicken Patty]

CP those Pics always look sweet.

I have been tweeking my 3Dmark06 for the last few days, plus the temp is a sweet 0c, so i poped in the "DO" and got a few more GHZ for the IGLOO's last blast.......

thanks dude. Have you tried clocking that thing with HT on, what did you get?

I do agree with the GTX 295's doing horrible in 3dmark 06. I got almost 27k with two 4870's and at 4.3 GHz. Now in vantage, they are monsters

Whelp, I made some progress today. I tried what was suggested and upped my memory voltage from 1.60V to 1.63V and it seems to work, with a base clock of 205, which is good for now. Now I have the cpu at 3.9 with a 19 multiplier, and my RAM seems to crap out at a base clock of 207 of higher, with a 1:4 memory to uncore ratio. I have tried 1.70V with the RAM and got those errors in LinX, SuperPi, Prime95 and Orthos using a base clock of 209. Then I bumped it down to 207 and got the same problems. Then went to 205 and it seems to work. I only tests Linx now, and will post that pic. I will test Super Pi and then run a much longer test of Linx, then Prime95. But it made it through the 1st 5 passes of Linx, using 4gb of RAM, whereas before it was only making it into a half a pass.
Now my memory now is running almost 150mhz a stick over the "rated" speed which I am damn happy with. Will run Memtest+86, but even with running the Ram at 1680+ it passed Memtest+86, but failed all those other tests. I am going to play with voltages to see if I can pull some down to reduce heat and see how far I can go with a multiplier of 20 or 21, but my experience before was a base clock of 185ish would bring me into the wall and would not let me hit any higher base clock even running close to 1.45 volts on vcore and 1.40volts on Qpi, not sure why. Maybe I do not understand the idea of multipliers that much, but I will try it out with the base clock of 200 and see if I can get into the 4.0+ 24/7 range. I was able to hit it before with turbo on, but that I do not consider a true 4.0 overclock since turbo is doing the extra push.
I was also thinking of getting new RAM, possibly 1600mhz rated ram, I was looking to spend like 160ish, but I do not need the best one like the cosair dominator which are nice but like 70 bucks more than the rest, any suggestions? trying to stay within 3x2gb sticks, but I do not want to throw the topic off. Will report back with the other results I come across.

If you bought new 1600MHz ram it would just be ram that runs at 1.65V. Honestly you are doing fine with what you have now. I have run on 1066MHz ram that is overclocked to 1600MHz, but now I run at 2000MHz with ram that makes people touch themselves. My point is... unless you're going for the 2GHz mark with ram you don't need to upgrade.

IYo yo yo, CP love those shots of yoru rigs, your always changin the fluids, love that look..
I did run the same numbers and got a 25k so with HT on it drops like 2-3k.

Also i am wondering what a good score is in Vantage with Physics off, i ran the cards and got over 40k on my last Vantage run, I ran it today with Physics OFF and got 35k,. I am wonderign if that is good or not,.

I am also wondering if i add a card for physics with the 2 295's will i get any point gains....


Rock and rtolll

 

[Jakethesnake011]

2Ghz is not needed for me right now, plus it is twice what I am looking to spend. Thanks

thanks dude, but i've never owned an nvidia card, so i wouldnt know what is a good score with it on or off. Maybe somebody else will chime in and help you out on this one.
