If you get a chance could you do this test here..nobody that ran that for us with a pentium-D got close to 4ghz.

I didn;t run that exact test, but my 820 @3.5 vs X2@2550 let me deduce it would take ~4.5 to beat the X2@2550 in the tests I ran. The Pressler core is the same, but @65nm, so I didn;t think there was anything to be excited about. I will be glad to run any tests I can with either of those systems against a 9xx@4 ghz.

but looking at AT's latest benchmarks i would say a 920 D at 4Ghz will pass everything in the gaming arena, or at least come very close...looking at the latest AT benchmarks the 820 at stock speeds even is extremely competetive in 2 of the three gaming benchmarks...http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2668&p=8

it just depends how much of a boost hyperthreading gives the EEs, and iirc it wasn't that much in most cases...so i would say if the 920 scaled according to that data it would be posting some serious scores in those games at 4Ghz plus...

The Presslers seem to be hitting upper 3's to 4Ghz on stock cooling/stock voltage most of the time. The max ceiling is almost the same as that of the 955XE, so there isn't that much binning going on. The problem I forsee with the 920 is that to reach 4Ghz, you need about a 280Mhz FSB (extra cooling on your NB/VRM's and the fact that you need a good motherboard to actuall be stable at 280+ FSB).

Well my Pentium-D 830 sold for $265 so as soon as the payment clears I'll be ordering a Presler and seeing how far it goes on water cooling.

awesome

keep us informed :beer:

hmm. This could get interesting.

 

[Cooler]

Newegg has it that 920,930,940,950 have HT as well it must be a typo.

 

[Socrilles]

the 820 at 3.5 ghz will not scale directly to the 930 at 4 ghz, I think this is true because you are also getting an increase in FSB....the P4 has always been inhibited by low clock speed and low bandwith, however with the high fsb/clock I think its potential will come out

In terms of performance per mhz it should be identical...except ofcourse it may run faster due to the base smithfield may have been throttling!!! hahahaha...

I think the only redemption the presler has is perhaps its ocing capabilities....The moment you get these things back up to 1.4v plus they should be hot again....


Guy with the 930...how hot are the temps being reported...Also run it with dual instances of something or a program called S&M (it is multi capable).....

My system never sees greater then 50c running dual FH for 3-4 months....

My system idles at 85-86 degrees F, and under peak use during gaming and such gets up to about 96 degrees F. I am using an older Koolance Exos system (Not V2). I'll go run the encoder and see what happens!

Is that the probe temp or the diode temp?

 

[phr0m]

thats has to be the probe temp, no way thats the diode temp

That is the probe temp. The Diode Temp is lower at 70 degrees F (which I can't see as being correct).

 

[Markfw]

70c I could believe.

 

[AkumaX]

so 4.2ghz + on a 920 and such.. what do you think, 280w-300w on load?

 

[Avalon]

Come on, let's see some 920 overclocks with some :camera: !

Welp if no one else will post results, I shall:

So far so good, overall the 920s clock the best out of the 9xx series (go figure). I have one of the better chips and a friend of mine has 4.4ghz stable on water. (4.6-4.8 benchable)

On average the max clock with no vcore boost is roughly 3.92ghz. Max with vcore sits at roughly 4.38ghz (water cooling) air cooling sits at around 4.08ghz

The only cedar mill on record right now is a 661 and it is doing roughly mid 4.3 on stock voltage and cooling. I expect this to grow to ~4.8 on water with voltage, possibly 5 depening on how his scales

I calculate my chip to be aproximentally 221W on full load. Temps reflect it as I am pushing 60C from 42C idle. For cooling I am using an XP120 with multiple Delta fans.

If I were to profile the 65nm chips from Intel atm I would characterize them similar to what Winchester was like a year ago. Excelent TDP, poor ramping with voltage. Most of the chips need 1.5v (up from 1.3) to do much of anything in terms of speed.

Im sure this will improve with time but overall its so-so.

you seem to have forgotten that Intel processors use DDR2 memoryl. Overclockign should be no problem.

As a common rule most i955X chipsets max out at roughly 340 FSB and the i975x chipsets max at roughly 380-390 depedning upon voltage. That being said, the chipset will not limit anyone's progress to 4ghz as it clearly hasnt affected mine.

Overall if you want to sumarize the threads at XS: PcCI2iminal's 930 is what you can expect on average out of most 930s and my 920 is what the majority of 920s are clocking to. (yes the 920s are doing significantally better, especially the batch from mwave.com)

So, I'm thinking about upgrading from my D 820 (Which I got 4 weeks ago... ha ha) to a 930. What kinda speed do ya think I can get outta this thing. I thought that if I got a good Zalman on my D 820 that I could pull 3.5 or so out of it, but these things are so freakin hot you could literally heat your apartment with them if you leave it on 24/7. Are we really thinking I could hit nearlly 4Ghz with one of these bad boys?

I think you will be able to get it to 4ghz pretty easily. The only reason my 920 isn't going any higher, is because my motherboard won't let me set the FSB higher that 265mhz, but I am 100% stable at 3.7ghz, 1.475v. I was getting 60c load at 3.64ghz on the stock heatsink, compared to 70c load with my 830@ stock speeds.

 

[ND40oz]

I got my gigabyte 975X board today and it's running a 640 until my 930 comes in. It's a PIB from Dell, so we'll see how it clocks when it gets here. I'm hoping for atleast 4 gigs on the stock cooler.

 

[pookguy88]

I want to see more benches of the 920 vs. a good o/ced Opteron or X2 (say, 2.6 Ghz). Anyone have any?

 

[Technonut]

Currently testing a 920 @ 4.2GHz.... (watercooled) As soon as I get 24 hours of dual SP-2004 under it's belt I am going to start a thread.....

Just water cooled? Not gonna put in on your vapochill?? What motherboard are you using?
