wat feature do i hv to enable in order when my cpu is idle,then da core speed decrease..
when i play games,da core speed increase..
i dono la wat its name.. rclxub.gif
wat u said is i can just turn all da functions?

The feature is Intel SpeedStep Technology (EIST), a power saving feature for lntel processors
it lowers the clockspeed of your CPU when ur system is idle

unbelivable. is this 920 the same 920 that u have been using before 980x? and where's your 980x?
*
Yes the same 920, but stil couldnt exceed BCLK 220 with this new mobo. I think ive hit its max BCLK at this x21 multi. Can boot 225 but not stable = useless. Might try lower multi. For me, Classified3 = Classified E760 + USB3 + SATA3. My 980X has been sold to someone long2 time ago due to urgent demand. tongue.gif

Can I bring my i7 920 over to your house and let you clock to things like 4.6GHz? Lol.. Even with CM212+, anything above 4GHz is too hot to handle.
*
4.6ghz is imposible for aircooling. The best coud go is 4.3Ghz HT off @ 1.31v touching 88c, with table fab blowing towards pwm

QUOTE(clawhammer @ Dec 13 2010, 02:23 PM)
Maybe you can get a better HSF from Thermalright or Prolimatech? That should work a bit better but it'll still be around the 80C I believe biggrin.gif
*
yes indeed get a better air cooler ie Vernomous-X, Megashadow etc... Or H7O. Above 4.4ghz pls get a custom wc hehe.

da more uncore frequency,more score for benchmarking?

Some memory intensive applications will benefit more from a faster uncore, roughly 3% I'd say but may vary from app to app.
3DMark is one of them.

Get a Corsair DomGT 2C8-9-8 for RM8XX only right now
On the other hand, my Elpida kit is still doing great and kicking in my rig

Just to share for those Elpida collectors..
List of some Elpida kits from Super Talent
Note that their 2000C7 is better than my DomGT 2000C7 in timing specifically tRCD
7-7-7-21 vs mine 7-8-7-20.. Anyway it's been reported (confirmed) that Elpida chips will die (degrading) after some time, likely a time bomb. It is disappearing from the market.

guys, is it ok to run d dom gt without the fan ?
im using d new rev7.1 dom gt 2k 8-9-8-24-1n 1.65v
cstkl1 reported able to run XMP profile at 1.5v
might try for 2k cl7 at 1.6v .

d question is it ok not to have active cooling cause my tubing right now is blocking d fan .
cannot attach them .
*
U might wanna try tighten timings:
7-9-7-24-72-1T, 1.56v
6-9-6-24-72-1T, 1.66v
No need active cooling unless u go insane vdimm ie over 1.8v
1.7v+ is still safe and cool, avoid noise pollution

For 4Ghz HT the best juice is 1.25v only. HT off is even lower.

Do u rilly need tat much voltage for 4GHz? With that insane vcore for sure will overheat. Try this.

Good job mets. u shouldnt sell ur goldy last time. Goodbye to ur Elpida lol.
My 2kC7 can smell the graveyard yet, hopefully at least until next year huhu.
Meanwhile I managed to pump more vtt with E770. My last E760 was capped at 1.525v only, hence now can do uncore more than 4.4Ghz @ dram 2200cl8. But gtx580 SLI doesnt seem to allow me to play with PCIE clock more than 100mhz, one of the gc will disappear at PCIE 110. While i need this to do stabilty at 4.6GHz core. Hmm mem low gap is set to 2GB.

QUOTE(metsatsu @ Dec 24 2010, 09:30 AM)
Hhmm.... I thought about that too.... apparently yuanbao still has it... do u seriously think the IMC and the core correlate similarly when it comes to the voltages. last time when I still had my 1600c7 GT, it just couldn't do uncore 4k, so I thought it could be a crappy ram. then I changed to that faulty 2000c7 and same thing happened. So i'm not sure whether if it's procs fault or the ram's fault at that time. but now i know for sure that the 2000c7 was faulty. but how would we explain on 1600c7? maybe it just simply can't do 2000mhz dimm?

Alvin currently owns the 1600c7 ram i mentioned, not sure whether if he has actually tested it extensively. hopefully he can come in and clear things up a bit.

I saw cstkl1's posts on this CMT6GX3M3A2000C8 in extremesys. what it's capable of doing is pretty good. btw, I noticed that my 975 can do 4k uncore @ VTT 1.375v. tried 1.35v it will BSOD in 20 minutes. for that VTT i would say it's pretty good yeah?


Added on December 24, 2010, 9:44 amcorrection. that 920 was sold to bigsaver


Added on December 24, 2010, 9:47 am

lol now i know i owned this before! shocking.gif
*
Core, uncore, dram all related to voltages bro
Core is linear to voltage whilst Uncore reacts exponentially to vtt.
For me all D0 could do uncore 4ghz easily due to better IMC vs C0/1. Just that u hv to choose the correct vtt.
Ur 1600C7 should be able to do 2000C9 with higher vdimm and loosen timings.

Guys if u dont mind me asking..
Whats your take on the Sabertooth X58..?
I mean compared with the Rampage and Classified and stuff..
In terms of CPU overclocking and memory support..?

Almost bought a Rampage the other day.. But i thought i 'd do
some research first.. smile.gif
*
For sure R3E is better than Saberbooth. TUF designed Saber is built for extreme heat n cooling. U might also consider r3formula which is as good as R3E. I like its TurboV, looked quite informative than the R3E.
Asus wont b that stupid enuf in pricing.
Classy wins in Mem oc amongst these boards. On top of that, Gulftown seems to prefer R3E than Classy. But i had hard time playing R3E bios than Classy. maybe im more familiar with Awards bios like what Classy n DFI are using lol.

i gotta finish up my project ASAP and start clocking back .
d r3e been sleeping for quite some time already .
hopefully no leak on my new block .
will definitely try out for 4.2k uncore this time ^^,
no more worry for crazy temp on mosfet .

Com'on let's finish it asap and break it to the limit.
Make sure that all the fittings sit tightly and conduct a leak test before running this RMA prone mobo.

Just to share something which Classy3 and DomGT could boot:D
