805 at 4GHz sux...533 TO 800 BUS AT STOCK VOLTAGE!

[Crashman]

Yeh, you've all read the article. 4.1GHz sound impressive until you realize the chip required over 1.65v to reach 800 bus (4GHz), and that's well beyond the voltage causing Sudden Prescott/Smithfield Death Syndrom.

Yeh, all the reports I'm seeing is that the voltage required to make short order (ie, only a few weeks of operation before death) of Intel's 90nm parts is around 1.55v

How about 533 bus to 800 bus at STOCK VOLTAGE? How about doing it using the BOXED COOLER without overheating?

I got the Celeron D 310 here, took it from 533 to 800 without raising the voltage. That's the same level of overclocking as the 805 at 4GHz, but it doesn't require even so much as an overclockable motherboard.

But wait, you can do it without overclocking the board? Yep. Pin mod makes 800 bus. Pop the CPU into any 800-bus supporting, Prescott supporting motherboard. Voila.

When i got my prescott, i'd heard that 1.55v was the upper limit, yet i guess

i like living dangerously, as i've been running mine at 1.55-1.5625 for almost

a full year. I even tried a few times @ 1.60v 8O , but that was too much for

my HS/F. My point. I guess i'm lucky. 😀 My 3.0C died from SNDS, but

even though i'd heard that prescott didn't like over 1.55, i've never actually

heard of one dying from it? Is it as popular as it was for Northwood?

errr... what if it's got no pins? 8O

 

[Crashman]

No pins like the 311 rather than the 310? You'll have to figure out a new way to bridge the contacts😛

 

[illicitsc]

u can only pin mod 478s, so its impossible to pop a 775 or u fuck your mobo

 

[Crashman]

Actually you should be able to insulate a contact with a drop of nail polish or something perhaps a bit harder, so long as the coating is thin.

And you could probably bridge contacts with conductive paint as well. Only the center of the contact gets poked, so bridging should stick at least to the edges of the contact.

You just need to find someone with guts, and a steady hand.

 

[hashv2f16]

who even knows IF these LGA chips that have no pins can be pin-modded to suddenly gain an extra 266 on the Bus, with no extra current draw??? so how did you 'achieve' this anyway?

 

[Crashman]

OMG! A noob perhaps? I modified a 310, others were asking about LGA775 while the 310 happens to be Socket 478.

And how did I get an extra 266MHz out of the bus? WTF? 533 to 800 is only 66MHz, as 533 operates at 133MHz clock, and 800 operates at 200MHz clock.

And no extra current draw? I never said that. I said the 310 can be overclocked at stock voltage. Amperage and voltage are two different things, the processor does make more heat, which means it does have more current draw EVEN WITHOUT A VOLTAGE INCREASE. Though a little warmer, it's still far from hot, around 65C max using the stock cooler.

So try to wrap your mind around the concept that nothing I said negates what I previously stated: The 310 can be overclocked from 2.13GHz to 3.2GHz, using the stock voltage and stock cooler, and a pin mod makes the changes work even on a board that has no overclock adjustments.

You crack me up Crashman....You remind me of "ME". ..LOL

I love sarcasm, combined with witt. Cheers

So let's just say that one takes the 805 to 3.2 instead of 4.1. Dual Core compared to a Celeron D310 Single-Core would sure be a fair comparison I bet...NOT!

I'd like to see the Sandra CPU Arithmetic Benchmark for the Celeron D310 for comparision purposes of course.

Haha. I called it right on the money in my post when I first read the article. I stated that if it ran at that speed stable, without burning up, then Intel wouldnt be selling it as a 2.66 now would they. If its sounds too good to be true, it usually is.

What about AMD with 165/170 Opterons.....to good to be true too?

Initial excitement begins when raising the speed of the FSB from 133 to 166 MHz. To our utter astonishment, the CPU ran at a clock rate of 3.33 GHz without any problems at standard voltage levels of 1.3375 V, even when both cores were fully loaded.

They still recommended a Zalman CNPS9500 from this point forward but as you can see, they kept the stock voltage of 1.3375.

I would have thought that by now you'd be bored with this grandstanding, but I guess crashman has an insatiable urge to satisfy his ego. :roll:

Old news. My 310 could go up to 3.6 on stock voltage. I bought and pin modded mine last September. Posted a thread on it at Anandtech forums. You still can't compare a 310 to the 805, as the 805 at stock settings will still crush your 310 at 3.2 GHz. Still, for those who don't need dual core, and who prefer Intel, the 310 is hands-down the best bang for the buck a person could buy. At 3.2 Ghz it is roughly equivalent to a 2.6-2.8 GHz hyperthreading P4.

 

[Crashman]

I thought all this grandstanding was about "best overclock". It can't be about "best performance" as you can overclock nearly any faster processor to get better performance than the overclocked 805. It can't be about saving money either, as the rig needed to get extreme overclocks out of the 805 will cost you more than simply overclocking a more expensive processor using cheaper parts.

If it's about "best overclock", the Celeron D wins. If it's about "Best Price", the Celeron D wins. If it's about best performance, overclock your FX-60 to its limit. If it's about "Best bang for the buck", an overclocked 920 would probably get you more...out of cheaper cooling.

 

[joefriday]

There's no bragging rights in best overclock unless you plan to go for world records. Best performance per dollar is the key. Trust me, I wouldn't think of ever water-cooling an 805 either, as it seems to make little sense to spend as much on the cooling of a cpu as the cpu itself. However, an 805 clocked to the 166 fsb (3.33 GHz), can be done under stock voltage, and using the stock cooler to boot (Tom's could not do it, but other reviews of the 805 showed it to be possible, so, as in all things, it is purely a crapshoot). At this level, the 805 is equivalent to a stock x2 3800+, which is quite impressive indeed.

I already agreed with you that the 310 is the best intel single core cpu for the money, as long one does not mind using an "obsolete" platform, with no possibility for dual core upgrades. I anxiously await the Celeron D 352 and 356 cpus, which are supposed to debut in the USA in a month or so. we shall see what the pricing will be. If it's low enough, it may take the crown as best single core cpu for the money of any Intel or AMD, as it can hit 5 GHz with the stock cooler. Here's a review of the new Celeron D vs 805. It's a horribly-executed review, but at least we get a glimpse of the 356. The next link is to extreme systems showing the 356 at 5 GHz. As long as the D's price is well below the 805's price( ~$75 -$80 would be nice), it will be a sure winner.

Hey, it sounded very much like you were implying so. I'm just clearing that up ok..

800mhz - 533mhz = 266mhz
266/4 (for QDR) = 66mhz. And if we're getting technical here, what's commonly reffered to as the "bus" is the QDR frequency, and the "FSB" is what's measured before QDR.

Well im running water cooling with my 805. This enables me to run 3.8 constant with low idle temp of 35 and a load of 45-50.

What I did was buy the watercooling(which im sure isnt going to be only for this setup but for others later in life) with the money i saved from the cpu.

Hey 3.8 ghz isnt anything to scoff at. Even though yes its a intel cpu which im actually happy about. My AMD expierence was spoiled due to the fact that i actually require to multi task and i wasnt going to spend the best half of my salery on a x2 chip that was going to run slower than my 4000+ even though it ment two cores.

 

[hashv2f16]

that's nice.. but it still doesn't explain how exactly you pin modded your socket 775 celeron d

its about performance for the cost.


"It can't be about saving money either, as the rig needed to get extreme overclocks out of the 805 will cost you more than simply overclocking a more expensive processor using cheaper parts"

WRONG.

just look here cel d 356 @4.8ghz d 805 @ 4ghz fx 60 @ 3ghz

out of the three what the best "bang for the buck" funny stuff right here "Although the FX-60 beats the D805 easily in the CPU test the overall score is in favor of the D805, which is weird, repeating the test several times didn’t change the outcome. The Celeron D 356 has a clear Ghz lead but it doesn’t translate in better performance as it trails the other two configurations." LOL

 

[Crashman]

Wrong? Try a 920 at 3.73GHz, I bet it's a tie with the 805 at 4GHz, and gets you stable using nothing more than a $40 air cooler and standard DDR2-533 at a 1:1 bus frequency ratio.
