BLOOMFIELDS CLOCK THE SAME

[ViRuS2k]

well thankyou for that information sherlock lol
but you are completely wrong not all 920s or 930s can hit the same as another one can but generally most of them can

what about the wafer quality between the inner and outer areas of wafers
generally speaking though most 920 d0s can hit what there big pricey brothers can do but c0s are another kettle of fish all together and the reason most people go for the price extreme versions is because of there unlocked multiplier.

Great thread!

Just so I'm 100% clear what to buy today, will I notice difference upgrading processor from 920 to 950 (I know how to overclock very well)?

Opinions needed everyone - I live local to OCUK!

Thanks guys....

 

[jrwagh333]

they are NOT speedbinned

explain why i have three i7 920 cpus on my desk at work that clock like demons

and outclock 950s

So therefore they dont all clock the same do they

Might it be easier to teach folks to learn how to use the search function?

no matter tha amount of JD i have drunk and the amount of spelling mistakes that Jon and gary have poijted out

i can still clock your bloomfiled cpu to 4.2ghz on any cooling other than stock without drama

Even this cooler?

My recommendation is this, if you have or are looking for a faster or buying a i7 cpu than what you currently have then dont waste your time. as 98% of the time you will be moving from a 920 to a 950 and getting exactly the same performance

My advise you dont need any i7 thats quicker by multi alone from the 920 and if you cant get the 920 get the 930 its all you need.

Hmm, seeing as I'm an overclocking noob I think I'll post my question here. I'm running a 930, I'm struggling to get it to 4ghz from bios.

It's currently running at 3.8 ghz. I've put bclk.
It's 185x21
I set everything else to Auto. The ram is corsair dominator. It's 1600mhz and has stock timings of 7-8-7-20. However, it's currently running at 1800mhz and 9-9-9-24.

At the moment my cpu is watercooled and reaching 66'c on load. It idles at 38'c while gtx480 idles at 28'c . I can get to 4ghz only by using Asus TurboV program, and setting bclk to 190. If I do this in bios, pc won't boot and says 'overclocking error please enter setup and change'

Help me? Thanks

Run the RAM at 1480 MHz instead (8x multiplier).

I suggest you set everything to manual in your bios write the timeings of your memory down and manual set them to 1600 T1 command.
set your Uncore to 3200 and Multi to 20x and bclk to 200

dont forget to set your voltages manualy aswell bump the iho up a notch and vcore aswell as memory voltage to your memorys default voltages.
if your board has load line calibration enabled leave it if not enable it.
then bump up your vcore and vcc untill you get stable.

Follow this guide : http://www.techreaction.net/2010/09/07/3-step-overclocking-guide-bloomfield-and-gulftown/

Its a life saver

 

[w3bbo]

Rofl @ Rich. Frustrating aint it

One word of warning though, I personally wouldn't leave everything at AUTO. a lot of manufacturers will hike up the voltage on AUTO when there is no need, increasing power consumption and decreasing hardware life expectancy.

 

[cloud84]

the quickest and dirtiest way i have found to work from experience is to go with the following:

bclk 200
multi 20
vcore 1.2750v
pll 1.88v
qpi 1.2750v
load line calibration enabled

& if your Useing more than 2 graphics cards

Bump your QPI to 1.290/1.300v
Cpu Pill only needs 1.80v
Cpu shouldnt crash with 1.250v

Also the southbridge generaly doesnt need any bump at all set it to its lowest setting not AUTO. as it only controls USBs and **** Northbridge controls PCI/lanes it could require 2 bumps from the lowest setting not AUTO as for instance on my motherboard on auto it bumps 1.350v into my northbridge when its happy as larry at 1.150v

Okay thanks guys, I'm going to be tampering for a while and see if I can squeeze some more juice out of this cpu

Also, realised I was a numpty re: cpu temps. I was using speedfan to monitor and I realised that I was reading the 'core1' temp rather than the cpu temp. So, one of my cores is idling at 37'c, however the actual 'cpu' value in speedfan is 22'c

So what can I expect to clock to when I get my 920 D0 this week?

..

I kid I kid.

Nice to know 4.2ghz will be so easy though!

lol

 

[Sayso]

4.2Ghz is achievable but i wouldn't say a definite depending on board/coolling and CPU ive only had 5 I7s (920s)so haven't clocked thousands like Rich and they all needed different settings to hit 4Ghz.

Best and worst..i had one that would hit 4.4 at 1.32vcore and one that would only hit 3.8 at 1.35vcore both under water so temps, the difference was a rampage 2 and a P6T-SE.

Im sure Rich could make any 920 hit 4.2 on any cooling he wanted, but would he be happy running the CPU close to 100C in his rig?

 

[Martini1991]

Now I guess we know why there's people claiming instability in there OC bundles
Not every CPU overclocks the same, that's true with i7's the same as it is a Phenom II.

 

[rjk]

So therefore they dont all clock the same do they

speedbinning suggests that the higher rated chips should overclock further.

in actual fact the chips are identical and all hit the highest stable overclock at around the same speed. 4.2ghz ish

sure - put the chip on a good board and you might get 4.3 - 4.4 on standard cooling.

and yes, a lot of the early 920 d0 chips can outclock a current 950
but we are not talking stability.

at the end of the day, they are all the same when it comes to 24/7 capabilities.

all bloomfields are the same.
it seems that there is at least five threads a day on the same subject.

"is a 950 worth it over a 920"
"can i hit 4ghz on the 930 easier than on a 920"
"should i get a 960, this cpu is surely better than the 920"

every X58 does 200BCLK
every bloomfield is capable of 21 multi

this is no mystery

 

[Phoenixdancer]

My X58A-Ud5 cant get mine passed 200 BLCK... cant get 4ghz stable at all.

Just purchased a new I7 950 to replace my I7 920 as i feel its the multi letting me down.
