Intel 4.5GHz & 5GHz LinX Stable Club

[Major]

How come I only have 49 GFlops at 4.4 Ghz??? Not enough voltage?

Try selecting "all memory" when running Linx


Has nothing to do with voltages!

ok I'll try that

[Dark-Energy]

Well the batch on mine is L932B343 Pack date 9/16/09 but I found this thread here...

http://translate.google.ca/translate...%26channel%3Ds

From March of last year (2009) with someone of the same batch and got 4 GHZ at 1.175 volts...but that is way before the pack date on mine....seriously what? I'm confused...or maybe I am misreading it cause it's translated

How are temps at that speed/voltage?

best batch from W3520 nice score

best batch from W3520 nice score

Yup, nice result. Especially with relatively still sensible Vcore

i want one so bad.anyone got one for sale hit me up

[KaRLiToS]

Does raising PCIe Frequency to 110 Mhz will help me lower the CPU temps, I can't reach 4.5 Ghz, I have good watercooling kit, (check sig) and my stable voltage at 4.3 Ghz is 1.31 v (IN BIOS)

Thanks guys

[nizery]

Hi, I think PCIe Frequency don't matter at your problem ?? .... you need better batch (cpu)

[Church]

Karlitos: most probably you'll be able to go higher with vcore ~ 1.4-1.45, but performance gain will be minimal in % while power used/heat dissipated will increase 1.5x times. I've often seen people going upto 4.5-4.6 for benchmarks/finding limits, and then rolling back to whatever frequency are more sensible in power usage for running 24/7 (usually 4.0-4.3 with very little voltage bump).

Lol, I put mine up on Amazon but you won't like the price.

[Anth Seebel]

How are temps at that speed/voltage?

cooler: idle -42C, load -37C, real temp 3.46: -6C idle , 34C load ..

thankyou for your kind comments

Hey zalbard, when will the list be back up on the first post ?

[rubber5]

hi everyone i just wanted to know a noob question
i know cpu's have millions opon millions of transistors but if one of them stoped working will the cpu become unstable under overclocking
or give some sort of problem thanks

If you had a cpu with only one transistor busted, I would pay you amazing money for it hahaha. Defectivity rates for silicon are fairly high especially for such a large die on small geometry. Typically 20% of the die is set aside for what are called repair arrays, so as long as you don't have too many bad transistors on a part, it's usually repairable. This isn't a user process though, most parts are repaired at the factory via fuse burn, but it's possible some motherboards are able to do soft repairs via scan chain. Even so, most of the time you're going to have some stuff busted and you'll almost never notice until you hit some corner case.

wow i didnot know that thanks
its just i really wanted to know becuse i know its rare for cpu's to go down
but the million dollar question is how meany transistors will have to go bad before the cpu is classed as dead?

Lol quite the opposite, cpu's are much more broken than you think. It doesn't take many transistors really, some logic is not repairable, a defect in those usually means a scrapped or binned chip (it may behave at a lower frequency/temp combination). As for million dollar... I'd argue it's multi billion dollar question lol, test time makes up for 1/3rd of the cost of a chip. You try to test as much of the chip in as little time as possible, but test escapes are unavoidable.

yip your right about the billion doller question lol
thanks for that i wish i had the balls to push my cpu to 4.5 ghz i have an i7 920 d0 1.125volts bios @3.5ghz and it can go to about 70c max but about 65c when crunching
i dont want to push my luck cant really replace it at the mo lol

Hey zalbard, when will the list be back up on the first post ?

The OP is almost re-done, sorry about the delay. Will probably finish it by Sunday. Monday latest.
There is an emergency situation at work atm.

[PatRaceTin]

ahhh i can not remember the rules at 1st page

[lowfat]

ahhh i can not remember the rules at 1st page

1. Must use all available ram.
2. 20 loops of LinX passed.
3. 4.5GHz

[zalbard]

I brought the requirement part of the OP back up. I'm almost done fixing the list.

[PatRaceTin]

i hope this follow the rules

normal water cooling

DRAM Voltage is 1.94

[SteveRo]

@PatRaceTin - very nice and congrats! room temp of 29c probably isn't helping is it - still you stayed under 101 so as i understand it - no temp throttling - good job!
