Yeah, a 45nm deneb is a 45nm deneb


edit:
"Serving as the successor to the Deneb architecture, the first processor to utilize the Bulldozer architecture goes by the codename Orochi. This processor will feature more than four cores, over 8 MB of L3 cache and a pure DDR3 integrated memory controller. The Orochi is slated for internal testing in late 2010, with full-volume production swinging into motion sometime in 2011." - Tom's Hardware

do you believe orochi is a monolithic architecture, or do you thinks its a multipack-one

Looks like Legit Reviews got a nice X4 965. 4.2ghz stable on air. Now I'm thinking about it again........

little gem?

600MHz overclock for 8 mV over stock voltage?? (screenie shows them at 4GHz @ 1.40v) That's pretty damn decent. Someone hand-picked that puppy.

 

[Assassin48]

the question to ask are these retail chips in the reviews ?

again my 955 was able to do 3.8 @ stock volts on an am2+ board and was able to do 4.1ghz on a UD5P ( validation in sig )

was that a dice run bro?

I just got Featured in CPU Magazine! My name is Brentt, my Rig is the Third Picture!

I took first place in the case mod contest at Intel DesertBash 8

Also someone care to explain why i cant use sig pictures hosted on graebtech.com, i own that site!!!
It keeps telling me images are not allowed from there!

 

[Assassin48]

3.8ghz stock volts was with a stock HSF w/ ultra kazi on top on your foxconn board

The 4.1ghz was on water on UD5P

so whats Better for Overclocking a Phenom 2 Quad 955/965???


MSI 790FX-GD70

Gigabyte GA-MA790FXT-UD5P

DFI LANPARTY DK 790FXB-M3H5

UD5P Hands Down IMO

 

[eidairaman1]

anything on Asus?

Scratch that

Gigabyte Might be what I'm Really looking for in a Motherboard Packed with Features and Overclocking Capability

my crosshair 3 comes in tomorrow along with a Sempron 140

The highest i have seen it overclocked is 3.5ghz so i will try to push it at least that high

will let you know how it goes

hello everyone,

My brother his rig is a gigabyte 790gx AM2 mainboard with a PII 940.

I oced it from 3.0 to 3.4 through the multiplier, its perfectly stable but the chip does run get quite hot when stressing all 4 cores ( 70C ).
I have read before that OCing the classic way instead of raising the multiplier gives less heat from the CPU, and adds some performance increase.

But i have zero experience with that, would it be possible to write down a small tut how i should go about doing it? Also is there any room for undervolting when the chip runs at 3.4ghz?

Case is quite small but has zalman cpu cooling which is all on silent mode , so my aim is to keep the 3.4ghz + silence and get the heat down, thanks.

That's pretty dreadful, what are the temps like on idle?

On air cooling, no, not really... maybe 40mV or so.

Best way to balance heat vs noise is to use the PWM feature in your BIOS. Don't throttle your CPU fan if you are overclocking and putting heavy load on the processor.

First of all 3.4 Ghz is a rather pathetic overclock for the 940 even on air. Mine runs @ 3.5 24/7 and I've had it as high as 4.0 Ghz.
Using a MB that doesn't support the 940.

Now about the temperatures, make sure you're watching the right ones.You should monitor the of the cores themselves, and not the sensor labled "CPU" in most monitoring software.

 

[Paintface]

Im sure the cpu can handle more , but running 70C with full load on all 4 cores i dont dare to go higher cause of the temps , so i hoped OCing without touching the multiplier ( classic way ) would lower the temps a bit , but i have no experience in that.

i use coretemp to read the temp ( only has one sensor afaik )

Actually it should run cooler and more stable by overclocking through the multiplier as the 940 can run 3.5 ghz (17.5 x 200) at stock voltage. To do the same through the bus by raising it 233 could require a voltage increase, and will cause the ram to run at 933 mhz if your ram is capable of going that fast.

 

[Velvet Wafer]

new results.... i will try to work on 3.95 and 4ghz now.

EDIT:
4ghz is not linpack stable until now... but i work on it

 

[chuck216]

Come on velvet, push that thing. If my 940 can do 4 ghz on air your heatkiller should allow at least 4.5 ghz on the 955.


Paintface what's the vcore on that CPU? it should be able to run the clocks you mention at stock voltage 1.35 v which shouldn't run any hottter than at stock speeds.

 

[Velvet Wafer]

dont overestimate my board... the mosfets (4phase) are cooled by ramsinks^^

I guarentee your board is better than mine. I'm running on a AMD 770 / SB 600 chipset that Asus says only supports up to 95W TDP processors.


Also paintface I noticed you mentioned that 940 is using a zalman in silent mode? How do you expect that to cool a 125w TDP processor properly, especially if it's not in a decent case with proper airflow? IMHO if a CPU fan isn't spinning at it's maximum speed and pushing the most cfm it can then the heatsink isn't doing it's job.

 

[Velvet Wafer]

the problem is: my board is knewn therefore that it likes to blew without proper cooling

i dont know why i cant reach 4ghz linpack stable, but it could be voltage dependant

 

[Jakl]

So I will be getting my hand on one of the 965's , so now I need a good OC Mobo....

By lookin around, seems like the Gigabyte GA-MA790FXT-UD5P is the good OC choice. Anyone else have any other thoughts?

UD5P is the second best board the #1 IMO is the CH3

ive had the UD5P take a 955 all the way to 4.1ghz stable on water and i just got the CH3 a few days ago and the board is solid and well made, havent had time to play with it yet
