no need to laugh at the guy

You need to put the sarcasm smiley in, then.

dejanh..yes you are right..therefore i want the people see what real performance they get for the money with my chess test!
If you look to my list then you see clearly how good the core i7 920 is compared with the 940 & 965.

Hey there!

Well, strange things happen every day and today was one...

First things first, I love this chess simulation. It really loads the cores 100% (reported usage never fell below 99.2% on any of the threads, averaged around 99.8%), it is more representative of real life than Prime or any of those other things, and it really generates maximum heat on all cores. So, now that I am done praising you on to my testing...

I decided to give your program a whirl to see what kind of results I can get. Naturally, anything with 20x multiplier was a no go so I tested with 200x19, 212x19, 216x19, and then finally tried to do 220x19. Well, all went very good until I got to the last test. I upped the volts in BIOS to 1.5V vcore, 1.475V-ish QPI/DRAM. I booted, ran for a couple of seconds, then my computer just shut down and I could not reload into Vista. I ended up having to pull the battery on my R2E and manually restore BIOS2 to BIOS1. After doing that, I reinstalled BIOS 0804 to BIOS1 and for the first time since I bought this board after updating the BIOS the board actually rebooted itself successfully and prompted me to set the new BIOS settings! Whoa!

It gets better. So I decide, what the heck, I do not have any of my profiles any more, how about I just set X.M.P for memory (sets DRAM voltage to 1.65V and QPI/DRAM to 1.35V), leave all timings as is, all other voltages to Auto and set the BCLK to 200 and multiplier to 20x. I booted, started your app, ran it, and crashed about 4 minutes in. I was like "crap, here we go again with the 20x multiplier" but then I remembered reading somewhere that somebody said QPI/DRAM voltage should be always no less than 0.01V and no more than 0.03V away from vcore. So I grabbed my MM, measured the vcore voltage, then set the QPI/DRAM volts to be exactly 0.025V apart. Booted back into Vista 64 with the new settings, ran your app, and no crash! None, nada, it keeps going strong! I stopped it about 15 minutes in just because it had already stabilized on load and temps 5 minutes prior to that. Impressive! It looks like I at least managed to find something that makes 20x multiplier work.

Anyway, here is the screen (I forgot to save results)...yes, I am sure the volts can be lowered, but quite frankly I do not care at all. I am using all auto except X.M.P profile and I have manually upped the QPI/DRAM from 1.35V to 1.40V. Cooled with a CoolerMaster V8 using AS5, in a toasty 23C room with the computer stuck in a corner where there is barely any airflow :p

ummm, R2E bios 0804? where??!?

Yay! We alls needs ours RAIDs controllers.

Ok guys, calm it down or do I have to play Attilla the Hun here?
try a little patience and when you fingers want to type something nasty go get a cold drink and cool down before you post.
No one is perfect so if and when someone says something that isn't quite right cut them a little slack in your reply.
remember, no matter how smart you are or how much you know there is someone on this forum that knows more and is smarter.
Now friends first huh?
Thanks for reading.

[bmilos]

Well said.

Anyway, with the new bios and realizing that I only had 2 of 3 fans running on my rad, I am running prime for about 25 minutes @ 4.2 with a 21 x 200 @ 1.41250 and a vtt of 1.53750.

Temps are 80c solid under load and things are looking good.

[Guacamole]

I emailed Asus about this issue. Their support team is a JOKE!



How the hell can bugs get fixed then? What the hell is their support good for if it can't be in the loop? Thats the most BS I've ever heard!

Typical ASUS you shouldn't buy their boards if you need tech support from ASUS for real.. We are all aware that there tech support is a joke but there boards and bios updates are no joke... In addition there is a new bios out for the P6T Deluxe bios 1003 you can get it here:

here's 3.6Ghz 20x180 8 hours prime blend 64bit stable with 12GB of ram.


edit: using the Z18 bios. temps are 68C, 68C, 67C, and 67C on the cores.

[freshy]

i stopped prime after 3 hours last night @ 4116mhz HT on, turbo on, vcore 1.45v, qpi/vtt 1.435, dont wanna push it more till i know more about voltages, i still wanna see what clocks i get with HT on and turbo off, then HT off and turbo on and then HT off and turbo off

The one thing that the 965 allows is more control over what you want to OC your memory to. Given that, that's a hell of a lot of money to OC your memory a couple hundred MHz.

My i920 HATES 20 X CPU multiplier.

I've managed to run 211 BCLK, but at obscene Qpi/vtt voltages.

I'm hoping that as time goes on, Gigabyte will put out a bios that will allow me to use that x20 multiplier.

Right now I can run 211 x 19 pretty stable at pretty low voltages. It's just not worth running higher for me. The increase in heat and voltages just aren't worth the possible gains.

That being said, if I saw a 965 for $500 I'd jump on it in a heartbeat!!

mine is the same , hates 20 x multi, but i think they just need more voltage hope future bios will be better for us

Yeah, I am not going to lie but I am pretty pissed at the moment. I purposely bought a Core i7 940 because I figured they would be higher binned chips than the Core i7 920 and hence get better overclocks. I know this is not guaranteed, but at least in AMD world it held pretty true. However, not only can I not get better overclocks (tried 2 CPUs so far), but the i7 920 actually often beats my highest stable overclocks on air.

A couple of points I noticed...

(1) Lots of chips out there will not run 20x multiplier. Both of my Core i7 940 chips won't. Above or below that is fine.
(2) Voltage requirements and temps for same clocks are a complete crapshoot. My first i7 940 would heat up ~15C more than the one I use now for the same volts and clocks.
(3) Jumps in volts for additional few MHz are stupendously large (e.g., going from 200x19 to 200x20).
(4) Having 22x multiplier (23x turbo) on the i7 940 is actually a major hinderance in comparison to the i7 920 as running this chip with 4-cores/8-threads at 22x200 is basically not possible thereby making 23x200 practically impossible. Turbo sort of gives a multiplier for free, except that means nothing when you cannot run your chip at its default multiplier to allow for turbo in the first place.
(5) At theoretical top clocks assuming 200MHz BCLK (even) there is a 400MHz difference between top clock on i7 920 vs i7 940 which likely translates to at least 0.3-0.5V (likely more) difference in extra voltage needed to achieve stability which is again practically impossible as most regular i7 920 will already require too much voltage to run at their theoretical maximum of 200x21.

Overall, pretty pathetic. With the current state of affairs and unless you are a top-notch enthusiast going for the higher possible bench score with some amazing cooling there is no point in buying either the i7 940 or the i7 965 EE. Simply put, they are a waste of money.

i agree 100%

Hi


thats strange , im using 3.8Ghz @ 1.20v with watercooling (and BAD Thermal Compound)

playing GTA IV for 1 Hour max temp = 46º

and prime95 = 55º/60º

whats the longest you have run prime at and at what voltages and clocks, most of your prime screen shots that i have seen havent been very long, sorry if i have missed them,

stable to me is at least 8 to 10 hours of prime even longer, as i have failed prime even after 3 to 4 hours before

cheers guys

[Hot'n'Chilly]

Hey, quick question as I've been away from the discussion for several days. Who has gotten the highest OC thus far without volatage increases? I've been wondering if one of you guys with those "golden" chips that OC like nuts ever tried that out.

[Lukee]

I tried again last night and can't get a 20 multi to work at anything reasonable. Oh well, I guess I'm stuck until possibly another bios update.

[Guacamole]

Yeah the 1003 bios for the P6T Deluxe doesn't seem to fix the 20 multi problem either.. Seems so strange that I can rock 210 or 211 at the 19 multi but can't do 200 at 20...

[Splave]

200 x20 is working fine here. Maybe its a per chip thing?

[roller11]

Same here. In fact, if anything 20x200 is more stable for me than either 19x211 or 21x191.

is that with HT on ?

[roller11]

Yes, with HT either on or off.

[Classic Satch]

is that with HT on ?

Does having HT on affect the 20x multiplier issue some are having?
