i915/i925x feature overclocking prevention

[saaya]

http://www.xtremesystems.org/modules...rder=0&thold=0

appearently intel integrated an overclocking prevention mechanism in both chipsets that detect an overclocking attempt and make the system crash when the desired frequency is 10% above the default clockspeed!

asus abit and gigabyte claim to have found a way to trick the lock, but say their boards are still limited to a max oc of 15-20%!

This means we will only be able to run DDR-II in sync. DDR-II 533 and 667 will have to be run in async as the fsb is locked to a maximum speed of 240mhz (20% oc) or even less!

sick! i still think there will be a way...

[Kalway]

Uh ohs... if this is true Via will become the enthusiast chipset king

[Kanavit]

well, maybe because DDRII memory is already overclocked! i925/i915 can't handle higher frequency. The lock is there for stability. we are talking about DDR 533mhz, and DDR 667mhz. think about overclocking DDR 667! 10% is already big percentage.

Currently, DDR400 currently runs lower than DDRII, so it has much more headroom to o/c.

check the news www.xtremesystems.org

via and sis just delayed their pcie chipsets to Q4 of this year!

what do you mean with DDR-II memory is already overclocked?
and you think 10% is already a good oc? wth are you doing on xs then?

DDR2 667 is stock. 10% of that is a small oc and 10% isn't a big percentage, its a small one.

I think now is a good time to have stocks with AMD

Im just saying, i'm not gonna miss out on overclocking, since i don't o/c. DDRII will be plenty fast for me, I probaby will end up getting DDR 533 dual channel, and a Pentium 5 560 (s775) 1mb cache. i really like the new socket design, looks very easy to install. Looking foward to this. I wonder what the new DDRII s775 will do in Pi-fast , and Super PI?

installing a 478 cpu is much easier, believe me
just check out the reviews

why do you want to get a DDR-II system? just because its new?
a 915/925 system is slower than a 875 system but costs a lot more and is very ocing limited... so why would you want one?

[blinky]

hey saaya nice work on the front page man!

how come whenever an o is next to an n there has to be a dash between em?

DDRII uses 240 pins 1.8v vs DDR 184 pins 2.5v and uses less voltage to run at higher frequency.

LGA socket 775 is easier to install, than socket 478 because the pins are now on the mobo instead of cpu and that prevents bent pins on cpu. also, the metal frame is now used to lock the processor. So you be pulling out the processor when you want to remove the heat sink only.

thx

you mean on the front page? i see no dashes

and flash memory only uses 1.5v ...so? and ddr-2 doesnt run at higher frequencies, internally ddr533 is only running at 133mhz compared to ddr400 wich runs 200mhz internally.

and yeah, now you wont have problems with bent pins on your cpu anymore... now you will have them on your board

i never heard of anybody ripping out his P4 when he only wanted to remove his heatsink, but yeah, i guess this new metal claw prevents such thing from happenening.

but all this has nothing to do with its performence?
you mean you buy a new system because it is easier to change the cpu and your memory runs with less volts and at a higher external clockspeed (even though it consumes more power than ddr-1 and needs a higher external clockspeed to reach the same performence)?

imagine people at a lan party talking about their rigs:
somedude- hey man ive got this new mobile a64 oced to 2.6ghz on air.
geeks- coooooool
kanavit- but i can take my cpu out of my mobo and put it back in in 3.4seconds!
...

i mean yeah, the performence of the 915/925 is not bad, not at all... but you can get the same performence for MUCH less money or get much more performence for the same money. but how can you buy something just because its new... new is not always good.

Saaya, what do u mean DDRII 533 is running 133mhz internally? Are you saying DDRII is nothing more than quad pumped bus?

[Soulburner]

Its basically 133x4.

And I don't think you guys read the article correctly. Its 10% of the default CPU speed, not the memory speed. Intel obviously wants to do away with people getting 3.2 Ghz chips for the price of a 2.4 (for example).

and how do you think you can get an fsb more than 10% faster than the default fsb without overclocking the cpu more than 10%? lowering the multi?

cpu clock=multi x fsb, if you lock two of them the third value is locked as well...

lol, so your praising DDR-II but you dont even know how it works? :P

Are you trying to teach me how to overclock?

[STEvil]

may be able to run asynch, but thats trash if you cant get your CPU moving...

[Jrocket]

Im enjoying thinking about how frantic the marketing guys at intel are, trying to find some new acronym or name for processors that have the same performance . The only reason they are doing this is because the mobo manufacturers got really angry when the tejas got cancelled, and demanded they bring out a processor for that socket. The new perks of DDR-2 (dont know yet if it will be a perk) and pci-x are nice, but we all expected that anyways. The scary thing for intel is, is that the tejas got cancelled and they wont be able to port a well working dothan to a good chipset for another year. Im starting to wonder what they are going to fall back on!? There is talk of dual core presscotts, but I doubt they can bring them out fast enough. Also the heat will be massive. Also, a 3.6ghz processor is not expected until november, so Im wondering how long they are expecting to glide with the new chipset and old processors!?

Noooooooooooooooooooooooooooooooooooooooooo

Trust Intel to do something like that...

AMD Time.... Til they start doing the same too...

[Jrocket]

AMD will never lock anything as far as the FSB is concerned. They got big mostly because of the enthusiasts. They might give you less features for ocing for cheaper cpus such as the A64 A64 FX type deal.

[Minnyboy]

Off topic:
I'm still on the waiting train for the S939's to mature a little bit...

Sick of Intel & envious of these AMD64's since I went to the AMD session here in Melbourne....

On topic:
I can see why Intel are doing this as most of the population still thinks that a 3.0c will beat and AMD64 3400+ to death let alone and an AMD64 3000+

There's no way to tell these ppl that mhz doesn't sell... And if the majority of the population catch on that you can OC these suckers to speeds not even out yet, they'll (Intel) will be at a big loss as no-one would spend $800 for a CPU when they could get a $300 CPU & beat the $800 one...

Hypothetically, that is...

[Djuice]

Death to INtel!

[zakelwe]

There was talk of this a long time ago when the Intel patents came out and I thought it was scaremongerring, well maybe I was mistaken.

I assume Intel thinks that by stopping you going from 2.4 to 3.6 and saving money you will buy the 3.6 instead, whereas of course actually people will go AMD if the AMD line up is good, which it is at present.

I wonder what Ed at overclockers is going to say about this, he might have to actually say something nice about AMD OK, probably not.

When Canterwood and 800FSB came out you could lust after Intel, I cannot see anymore lust appearing for the foreseeable future.

I think now is a good time to have stocks with AMD

...and I'm holding.

Now if only more of the 939 boards show up so I can support the cause.

Remember that LGA 775 pinless allows more power to cpu because of greater pin density, which means dual core capable. that means it will be easier for intel to design a dual core processor based on netburst architecture on this socket platform. Tejas has been canned, prescott still lives though.

Overclockers, hobbyists, and enthusiast still make the minority of the market. Intels main profit is from business such as HP, Dell, IBM, Gateway, Compaq. these large corporations don't overclock but pay big bucks. Also, you guys can't ignore the laptop market which is completely dominated by Intel. the future of computing is moving in the direction of mobile and wireless internet.

Intel is loosing a lot of money to people buying a 2.4c and ocing to 3.2ghz. the loose more than they gain, hence the locking mechanism.

[macci]

So the new chipsets are not only slower than 865/875 but they are also poor overclockers
