Actually, first attempt at any kind of overclocking.

It can't be this easy with the 920, can it?

All I did was go into the BIOS and change these settings:

Ai Overclock Tuner from Auto to Manual
CPU Ratio Setting from Auto to 20
BCLK Frequency from Auto to 200
DRAM Frequency from 1600 to 1603
UCLK Frequency from 3200 to 3208

(The DRAM and UCLK Frequencies went up when the BCLK Frequency was raised. I then reset them to the new values.)

This is on an Asus P6T Deluxe, Core i7 920, Mushkin 7-8-7-20 at 1600. Cooling is a Thermalright Ultra Extreme 120 (new model, using fan it came with.) Case is a Coolermaster HAF.

Ran OCCT for 10 minutes to see what the temps were like.

(Check out maximums!)

I'm happy. Grin

One question. I notice in RealTemp, at the top right, at idle the multiplier fluctuates between 16 and 18. Under load, it is at 20. Why?

FSX runs fine... the problem
is you or your system

Run OCCT for an hour and make sure its the beta version for bloomfield.. and when summer hits it may not be as forgiving on the temps.. you are in der Canada, Aeh?

however, yes its that easy

As long as the Advanced CPU features are disabled as in Speedstep, CE1, Turbo, HT and the TM fuction the multiplier should remian stable and do remember that RealTemp v2.90 is stil beta so the readouts may be a bit quirky

Jim, you have Intel C-State Technology: Enabled, correct?

Disable it and see if the multiplier remains stable in readout

Typically once Turbo is disable C-State should not have any effect however with all the different BIOS and i7 being new, it could be why you see the change.

Turbo Mode and C-State work together

As long as the processor speed remains a constant I do not see any issue with it fluctuating in the readout

wow... those temps are extremely cool for such a clock..

I have the Antec 900 case and the same HSF as you, and on 3.8ghz it hits 78-79c under load

Yep, I'm in Canada, Eh. My play place is in the basement. Ambient right now is quite cool, probably 17 or 18 C. In the summer, it will get up to 23 or 24, so I'll keep an eye on it when it warms up. But so far, looks like i have a bit of room temp wise.

I did have c-state still enabled. Disabled it as you mentioned in your next post and RealTemp no longer shows the fluctuating multiplier.

I'm in the middle of a 1 hour OCCT (Bloomfield beta) run right now (and not having any problems surfing at the same time.

) I see that OCCT also shows the CPU temps. They are averaging about 3 to 4 degrees lower than RealTemp. Given your recommendation regarding RealTemp, I'll assume that the OCCT temps are not quite right.

Since the P6T Deluxe has the ability to store two BIOS profiles, I've now got my Standard (no OC) profile for regular use, and my OC profile for FSX use. I always like to reboot prior to flying in FSX, so changing the profile is no biggy. This way, I don't have to run at the OC speed all the time.

While on the subject of first time OC's, I figured I'd do a bit more playing around last night. OC'd my vid card (BGF 260 Maxcore) by 20% (core clock, memory clock and shader clock). Also bumped the fan up to 50% from default 40%) Did a one hour flight in FSX from Ottawa to Montreal without a hitch or glitch at all. Smooth sailing (so to speak.) As far as I can tell, the GPU temp may have reached the upper 50's. Definitely didn't get past 60. Profiles now created and will load automatically when FSX started and stopped.

Very happy now.

Also took a stab at OC'ing the RAM, but did not get anywhere with that. Most likely due to lack of knowledge.

Regards,
...jim

PS. 35 minutes in to the OCCT run, and the max temps are 75, 71, 70 and 68. Wink

Hello!

Wow, this makes me very happy to read!

I always like to get the best I can afford but why go with the 940 if the 920 can hit 4.0ghz this easily for so much less money?

I always hate to read posts by those that "cheap out" and then wonder why it's not OC'ing the way they like but in this case, is there a big difference I am missing?

i7 940 at 4.0ghz • Asus P6T Deluxe • 6gb OCZ Gold 1600 • BFG 285 Superclocked • Velociraptor 300gb HD • LG BlueRay Burner • Thermalright 120 cooler • PC Power 750W PS • Antec 1200 • Windows XP 64

Yea.. you sure are... he's in Canada and its cold there now

Adam is in Florida and it wasnt when he set up his clock which he could not go any higher than 3.7/3.8

A 940 will run 4GHz+ easier than 920, and, its memory multipliers are restricted which means memory choices a year+ down the line may be limited

You get what you pay for

No kidding. Woke up last Friday morning and it was -39. No need to specify C or F as it's only 1 degree away from where they are the same! And this is in a city that can reach over 30C in the summer.

Very true.

Will be interesting to see how the OC'ing goes in the summer. But then, I don't do much FSX flying in the summer. I prefer to do my other flying hobby. (See link in sig.)

Did another flight this evening. Teeterboro to JFK in my RealAir 260. Smooooth. Should mention that FSX settings are pretty high, even autogen at one notch from the right. Oh, and Nick, remember that comment about AA hitting hard on the TH2go? Not seeing a problem with AA at your suggested 8xS. Looks really nice. Give me a few days and I'll post some FSMark07 benchmarks (for whatever they are worth) and the FSX settings I've settled on.

Is Real Temp OK? Tj max was different compared to Coretemp on my C2Q.

Only v2.90 and above... current RC is v8

set TJMax to 100 and you are set to monitor Bloomfield
