OK, got the i920 overclocked

[SanDiegoPC]

I appreciate this forum greatly. Lots to read everytime there's a new processor! Next stop will be 4.0 but for right now, we're at 3.8 and the i920 is staying nice & cool...using the stock HSF.

Running Windows 7 (64-Bit) and Corsair Ram (8GB) on a Samsung F1 hard drive (1TB). I took the graphics forum's advice and stuck with my 8800GT Superclocked video card, since this machine is not used for gaming, just heavy use of Photoshop and photo editing.

I'm disappointed with the performace 'rating' FWIW that Windows7 gives the machine at a 5.9 as it says the hard drive is the limiting factor. This drive is supposed to be faster than Western Digital's Black series drives.

Here are my settings:
* BCLK 19
* Bus Speed 200
* QPI Link 3600
* RAM: 9-9-9-24
* DDR3 1603MHz
* CPU 1.3V
* QPI Core 1.3V
* CPU Differential 800mV

Why do you care about a performance rating? If the machine performs well at the tasks that you set up on it, why care?

I don't ... but I'm concerned that the HD was the weakest link. I specifically bought that hard drive because of it's speed ratings; I already did have the two 500G Western Digital blue drives from the prev build that's in my signature.

Run a couple HD benchmarks on it to see if it's an issue with the drive, and check the SMART readings if you're worried.

This actually makes sense since mechanical drives tend to be the slowest component of a computer. Get an SSD As a side note my Hitachi 1TB also gets 5.9, while my CPU is 7.6, Ram is 7.6 and videocard is 6.9.

My old Q6600 @ 3.4ghz got 7.1 CPU (implying my current CPU is only 7% faster), yet my framerates in Resident Evil 5 almost doubled... Don't worry about Windows performance index.

The only hard drives that get ratings at 7 are SSDs so 5.9 for a standard platter based Hard Drive is fine.

dude, seriously, do not set your goals on windows

3.8 and the i920 is staying nice & cool...using the stock HSF.

How is this possible at 1.3v? I'm at .875v at 2.9ghz, and my D0 920 goes from 34C to ~80C in under 10 minutes of prime95! With stock voltages I was looking at low 40s at idle to motherboard thermal beeping in prime95 after < 5 minutes. I can't even imagine higher voltage and clocks on that dinky thing.

Did Intel change the factory HSF? Because mine is just a joke.

Mine looks EXACTLY same as the one on the Quad 6600 I built years ago, in my signature. That chip ran three years overclocked. Four small fans blowing in, at the bottom of the case up front. One in the side, blowing down over the Intel HSF. Then of course the 750W PSU has two fans as well.

Keep 'em cool and they run fine.

I just wish this Asus P6T board had all of those headers for fans. I was using the Abit board for the Quad 6600 and there was an individiual power header on the MB for every single one of those fans I had blowing into the case.

It's not. He is probably not using the proper temperature monitoring software like CoreTemp or RealTemp. Mobo utilities are often 20*C off.

My Prolimatech gets about 68-72*C 100% load Prime95 at 3.9ghz and 1.312V. So there is no way that a stock 920 heatsink can keep a 920 @ 3.8ghz "cool" considering it consumes even more power. It may be a combination of very low ambient temperature and very high core temperature that's still stable (i.e. 85*C+). But I doubt it's the proper word is "cool".

man stock heatsinks suck for overclocking unless it's a low end dual core OCed to low 3GHz range without a volt bump. Get proper cooling and run your i7 at 4.5GHz or something

Yes, overclocking requires more power in the cooling department.

Is HT off? With stock cooling I was loading at 75-80 with ht on. I ordered a True for my setup in sig. Funny thing is I got a corsair h50 for 52 bucks for my home theater room htpc and its actually cooling my 920 very well with ht turned off at 4.1 at 1.26 loaded at 60-65 prime small ffts. With ht on it cries and runs to momma though.....I am hoping the true allows me to run 4.2 with ht on.

Mid 80's easy unless your room is uncomfortably cold.

 

[MangoX]

I don't know how those temps are possible with a stock heatsink... unless your room ambient temp is like 5 degrees C or colder??

My i7 non-d0 at 3.6ghz (1.35v) on a TRUE with 2 120mm Scythe fans (lazy to look up the exact model number) loads at 85-90C with all threads maxed out.

The hard drive is always the slowest link in a pc... being on this site you should know that already... right?

 

[nyker96]

just two question, isn't your RAM 6GB or 12GB? 8GB don't seem possible. secondly, is your 2x500HD in RAID? i believe that would be very good for video and photo editing.

Running Windows 7 (64-Bit) and Corsair Ram (8GB) on a Samsung <F1 hard drive (1TB).

The Samsung <F3 was the drive recommended.

I has two platters: higher density. It's faster than the three platter design in the F1.

There's a link concerning why higher density is faster somewhere.

At least at Newegg, the F3 is listed as $5 cheaper than the F1.

And, for speed: clearly an SSD as the OS drive with a spindled drive for mass storage speeds things up considerably.

If speed is the main consideration: SSD. If cost is the limiting factor, spindled drives.

Oh, Schnitzel! Ahh, well I own this one now.
