TPU's Core i7 Overclocking and Feedback

[Binge]

I just realised, this is a PDF from "gigabyte technical marketing" but if you can overlook it's somewhat "spammy" nature, then find the little bits of info in there regarding voltage, memory settings etc.. They were able to get their 1333mhz DDR3 3way ram up to 1600mhz passing memtest and still maintain a stable 4ghz OC

That guide is less than impressive. Look at my system specs.

Tweaktown has a PDF showing they just decided to set the bclk straight up to 200mhz since their multi was locked at 20x , then pulling the CPU volts up to 1.51v with bclk at 200mhz with turbo boost on at 4.2ghz 38C idle 53c load on air with a thermalright extreme 120 they are running 3x ddr3 1333 at 1200mhz here's a link to the PDF http://images.tweaktown.com/imagebank/Core i7 920 oc 4G 2008.12.12_(ENG).pdf

1.5v

turbo boost

53c load

on air

two words

HORSE SHIT

hey, I didn't write it The writer mentioned in there that they have a bios setting download to try. If you got the same board, you could try their bios settings and compare load temps to call them out on any HS but I'm sure there's some room for them to say something like, maybe the ambient temps are different in your tests, or "your thermal interface goo application might not be good enough" etc.. Although I doubt you guys would goof up a thermal goo application..

Binge, I tried to view your system specs but after clicking, it just leads me back to this thread for some reason.. Anyway, that PDF is just another person talking about overclocking the i7, and asside from the voltages, sort of reinforces the base clock settings to get 4.0

Something, that I found useful, well written in easy to understand English too.

I get 4.2GHz 200 bclk, turbo HT on @ 1.385v-1.41v That PDF is full of bull. They change settings that don't matter and over-volt.

very good. thats the point i been trying to get accross for a few weeks now.

Heya coodiggy. To be sure i was not calling HS on you, only on the
PDF writer. I do not have that MB but i do have a i7 920 and have
done much research and reading for my OC test. IMHO to get
53c on load, that chip would have to be sprinkled with fairy dust
and anointed with the blood of a decapitated chicken from a voodoo
ritual.

By the way i to have a Digital Infrared IR Non-Contact Thermometer
and my temp readings at the heat pipe of the chipset is WAY less
then the readings from multiple sensor apps in both windows and
linux. Needless to say there is no way to get a proper reading of
the cpu or chipset with this device since they are covered by a
HS, HSF or WB.

Thanks, yeah, I noticed the bump in voltage, I'm not a fan of adding voltage to get it to work. little off topic but on my 680i board with qx6700, I noticed the CPU clamp on the board would flex the IHS on the processor and required far too much compound to fill in the gaps, Wouldn't run stable at stock settings due to not enough thermal goo between the CPU IHS and HSF because I like to have a skim coat application of goo, very thin application.. This would leave about 30% of the IHS out of contact with the hsf base, had to go with the Intel recommended "blob of goo in the center" to get it to run stable. When you guys apply compound, do you do the big rice grain blob in the center?

Has anyone lapped their i7's?

Can you check to see if your motherboard clamp bends the CPU IHS when locking the clamp lever down?

If your IHS is reflective enough, you can see the reflection on the IHS start to distort as the clamp lever is locked into place. This results in poor heatsink/IHS contact, requiring too much goo to fill in the gaps..

I no longer use the motherboards cpu socket clamp to hold the CPU in place due to this;

I use the cpu cooling fan/mounting hardware to hold the CPU in, it's a little more difficult to put it all together, but results in a completely flat CPU/IHS/HSF interface that allows one to use "less" cpu thermal goo, gives better temps etc.. This might result in being able to use even lower voltages.

So your running 4Ghz as your 24/7 @ 1.305?

4.0 GHz @ 1.305v. I just noticed last night while running prime that under full load the vcore jumps to 1.350v.

 

[Fitseries3]

holy shit.....

fired up the sas drives on my new board.

 

[Fitseries3]

single drive

15000rpm sas

 

[Fitseries3]

raid 0 vrap 300gb's

 

[Fitseries3]

raid 0 sas drives

 

[smee]

holy crap...... dude i want SAS now

 

[spearman914]

Holy SHIT on the Raid 0 SAS. Thought it'll be like 150MB/s.

 

[Fitseries3]

2x wd 10k rpm 300gb vraps = $380

2x Maxtor 15k rpm 36gb atlas' = $100

overall...

SAS takes the win.

The 36GB's can barely install 2 games w/ vista. But for just OS, SAS pwns!

 

[Fitseries3]

they raid out to 72gb though. plenty enough for what i use them for.

the vraps actually look "dirty" in the benchmark.

thT STILL DON'SSOUND SO BAD UNLESS IT STARTS TO GET TO HOT?

Fit, man your giving us a schooling

well temps are mid 70's at that. I hope I have enough next check, its time to redo the water setup

 

[Chicken Patty]

got a question guys. I got the EVGA X58 mobo, my NB temps are about 76ºc under a run on prime, and my Vregs are about 88ºc, is this too hot, or normal?

too hot. Mine only get at the hottest 60C and that is rare.

 

[Fitseries3]

your burnin up CP

 

[Jupiter]

OUCH cp, that sounds high. Like Binge mine has never been over 60c.
Since i put a little fan on it, it stays below 52c.

Fit, dude your raid 0 sas setup, to put it in simple words FTW... damn damn dippity damn

maybe the EVGA runs hotter perhaps?

Anyhow, damn, get its time to buy some Bits Power blocks

Fit are they out yet?
