975 D0 Preview

[IanY]

Aigomorla,

Sorry to be a party pooper. Yes, these processors generally run a desired overclock and a lower voltage. Generally.

However, have you read all across the internet forums? Its a crap shoot. Some of the guys who bought the retail D0s from Microcenter, Tankguys, Fry's and elsewhere are having nightmares. Their new D0s are overclocking worse then their previous C0/C1s.

As with any overclocking, its entirely a crap shoot. You are working with a cherry picked engineering sample (as with most of XS) that may not be representative of what is on the store shelves.

All the rest of you, don't expect over 4.0 Ghz with a D0. If you get 4.5 Ghz, then congratulations.

Remember that people shut up when they are down and raise a ruckus when they have something good. For every person making noise about how great the item he just bought, there are easily two others who feel they got duped and are suckered.

Anybody ever heard of someone standing on a mountain and yelling "hey, I have a small penis" ?

Very nice, I'd be lying if I said I wasn't worried about 6 dimms lowering my current overclock. I have another 6GB kit of Corsair XMS3 1600MHz C8 coming in so we'll see how that goes. One thing I learned though was to add a large, cheap item with free shipping to speed things up on small items. Newegg used super slow DHL mailer (DHL to USPS courier) and ZZF looks like its using super slo-mo freight! I miss the days of free FedEx overnight from Newegg back in the day, although I still get similar service out of their NJ warehouse via UPS.

Do you have any links to those discussions? My MicroCenter certainly didn't have any D0 in some 40 samples restocked after the April 1st burn off. I've been looking but results are scarce being XS forums are still down. Also, Gary has two retail D0 from Tank Guys previewed on the front page, both doing 4.3GHz+. Sure its still a crapshoot, but the results so far look promising.

There's an active thread over at Hardforums in the overclocking section. [sorry]

And I can confirm that 12 GB of Corsair 1600 works well on the P6T6 Rev. bios 0407

I'm sure a Grizzly couldn't care less if your pundy is tiny if he's hungry. :laugh:

Definitely a lottery when it comes to O/C. People pick batch numbers, this and that but it's really like grabbing straws if you ask me.

With the price spread and potential overclockability of the i7 (not to mention the multiplier flexibility!) I wonder if the business of pre tested CPUs will return??

That's what I'm using in the video above. Exactly. (Corsair Dominator Memory)

Awesome thanks! I'll check it out.

Unfortunately I have the P6T vanilla, I'm not a fan of spending $300+ on a board, which is funny because only a few years ago, I wasn't a big fan of spending $200+ on a board. Hopefully I don't have any problems with the additional 6GB though.

The trouble is people who are insatiable. I would imagine 4 Ghz from a $300 cpu that is speced fro 2.67 Ghz is a pretty darn good overclock. But no, people want to do it at 1.15 volts Or take it to 4.5 Ghz on stock heatsink. Or pay $1200 to get a 975EE when there are no guarantees of a better overclock with multiplier adjustment.

I see all the tricks across the forums. Disable Hyperthreading. Step up the multiplier to something ridiculous (for the EEs) and the BClk all the way down to 150 or below, which makes your system suck wind anyway because your memory performance sucks, or loosen memory timings to CAS10 or something stupid like that.

All that to get to brag about that extra 200 Mhz overclock, or scream to the world that it can be done at 1.2 volts without a fan on the heatsink.

Very well said, good to have some sensible people on the forum, need more people like you. IMO 200 Bclk and 1600Mhz Ram is the sweet spot for i7's. My C0 920 refuses to work at 20 multiplier but 19 works great, giving me 3.8 Ghz, 3.2 Ghz Uncore and around 6.4GT/s QPI at a reasonable voltage. Very happy so far, don't really any more CPU power for at least 2-3 more years.

Got screen shots of that...I'd love to see them.

Your doin better then me...my sweat spot is 3.4, HT on, 17x200 @ 1.3vcore and no additionall PLL or QPI volts. 2.66 to 3.4Ghz...I can live with that!

Stability is relative to the task at hand There is no "absolute" when it comes to what one can define as stable. What might be stable for one thing (benching Futuremark Vantage, or Super Pi 1M) might not be stable for another (video encoding). I say as long as it doesn't BSOD for the task at hand, it's stable enough. Am I ever gonna run Prime95 for 24 hours straight so I can prove to a bunch of people it's "stable". Nope, because as long as it does what I want it to do, as fast as it can, I'm good.

The benefit of running a stability checking program like Prime95 is that it is designed to detect non-fatal errors in the computed results. Not all bad calcs result in BSOD.

Personally I'd rather not have excel or MS money using funny numbers, Pi()=3.15 FTL, when I balance my checkbook or do my work, but as you say everyone has a different view of "acceptable computing experience" when it comes to what they get from their rig.

that is a dangerous area to operate. outliers can be hundreds of mhz away from the "wall". the result can be random silent corruption.

 

[nyker96]

I like your test bed looks pretty cool. let us know how this chip turns out.

 

[Rick James]

Alittle OT question but best to ask in here. Will a Nehalem based Xeon E5504 work in an a X58 motherboard?

Stability is the ability to throw anything at the system and not crash. This is not to say that the code itself may cause something, we are talking about the hardware as a direct result of changes to the system specs.

If I'm encoding movies, and it can do so perfectly fine @ 4.6GHz, yet it fails P95 at 4.6, why should I slow it down just for it to pass P95 Assuming there are no glitches or errors with the DVD.

Obviously what you are doing is not important. If you don't care about corrupting your os then by all means run an unstable/unstable system.

Thank you very much for your compliments. However, I'm supposed to be a good friend of Aigomorla, the moderator And I usually end up being a thorn in his side... And he invited me to this forum! lol

Well I am pumping more voltage than you (1.375V, which goes down to 1.35 with vdroop on load) and my temps are ok for me but will be considered high by most of the people here. Most of my cores idle at around 38-40C, heavy usage and gaming peak at 60-65C. But 20 passes of 64bit LinX using the max memory makes the temps peak at 86C :shocked:. It doesn't really bother me much because outside of stability testing the processor is always operating well within a normal temperature range.

You know man I'll be honest, 3.4 with HT on at stock VTT, PLL and nearly stock vcore is a good result. My motives are slightly different, I am just trying to not go down on clock speed from my old Q9550

Aigomorla is a true blue enthusiast, I am sure everyone frequenting this forum knows this by now. Believe me I would love to be able to play with all the toys he plays with and yes I am a little jealous. The main difference is that he really knows what he is doing, uses the best possible cooling, great motherboard, his knowledge of the best stepping and batch numbers of a cpu and/or cherry picked ES CPU's etc. to achieve his awesome results. It is when the average person looks at his results and then starts to sweat because he can't clock his processor as high as him is when the problem begins.

I am under no illusion, I am sure if I gave him my chip he can probably get more out of it with lower volts and have it run much much cooler. I however got my cpu/mobo/ram/HSF based on a budget. Looking at the money I spent, I am truly happy with the results I have got.

 

[The-Noid]

Just got a 920 D0 that is 1.325 vidded. I think D0 might just be luck of the draw same as C0 stepping. Overclocking requirements are higher than any C0 I have had, although I only tried it a bit last night.

Boy I like your post, But the part I bolded. NOway. I have been involved with Stock car racing for 49 years. Your statement above is False . When you consider . People in racing . Get really really quit when they have something good. Only when they are sucking hind tit do they Blab .

LOL about penis remark . I don't know if mine is big or small. I never did a compare test.LOL I do have 2 Children . I have been with wife for 42 years never been unfaithful. The most use my penis gets is relief. Besides the guy standing on mountain has NEW Pills. He is in fact yelling on the Mountain . THe Drug industry has made me a mighty redwood. My question to man on mountain than is why is woody red. Ya have the tool but no garage to park it in . LOL.
