How many stable OC's above 4Ghz do we have?

[leoy]

4.1 @ 1.504 volts prime stable

Have it at 4ghz @ 1.42 everyday, or 3960 @ 1.4v

[gOtVoltage]

Ok heres my X2550

For Benching games i use the two Screens below.

For Max Stable OC while Gaming.


For Testing Max Volts and not going to crazy while Living up to my name
This was my origanal 24/7.



In My SIG is where its @. One day ill sqeeze more from the 550 , Just too many projects going on and im on a prowl for new chip to play with

Note: AMD's do like a little voltage,, I tend to go overboard.

Great C2 chip, I'd say Mine isn't that so great, but I went for high NB and DDR2 over 1200MHz with tight timings. I see more benefit from it, instead of some MHz more from the cpu. I like these unlocking beasts more than the "real" X4. It's more fun with them

Im waiting for the C3 550x2 to hit the shelf. Should be soon...I know i can order a tray C3 550 but then i couldnt look at Batch numbers

Also Athlon II's are suppose to C3 as well.

Wow, you gus are pushing some serious volts through those things for 24/7. I wouldn't go near 1,5V 24/7 on my chips, be it Intel or AMD
Well, an i7 @ 1,5V would produce like 300W of heat anway

AMD's are perfectly safe up to 1.5V (it's within rated specs).

I've been working on getting my C2 965 stable at 4 GHz... I thought I was there today but it failed OCCT 1 hour test with 1 minute left

Probably going to replace it with a C3 anyway. This chip seemed really really good (did up to 4.2 GHz windows boot at stock 1.4V) but getting it stable at high speeds has been tough. Maybe I'll settle for 3.9 with high Northbridge.

Got my new 965 C3 (need to update my sig again lol)
With a little tip from a friend I am already prime95 and occt stable at 4Ghz with only 1.44vcore on Windows 7 64bits



Thanks chew!

[mngdew]

It's not common to get a 965 over 4Ghz under 64bit Windows.
I've tried to get 10 different batches of 965 from different stores under 64 bit Windows 7, and I couldn't get any of them stable (20 cycles of LinX) at clock speed over 4ghz.
Only one was stable at 4Ghz with 1.46V.

Looks like one man's bad ln2 chip is another man's good air/water chip, but I already knew that .

Now I just have to sell one more to restock on ln2 and start all over again.

[crazydiamond]

looks like a pretty good air cooler

[Riska]

Here is mine 965 C3 i havent have time to play so much with it but it nearly does 4.0ghz stock vcore..

it is cooled with a XSPX DeltaV3 and 2x XSPC 360RX rads and a laing DDC 10w pump adn 6x Zalman ZM F3 fans on 7v

And can u please share those tips with us chew...seems like i need 1.5125 v for 4ghz stable.

wow! nice! ~4.0/1.375 is very impressive!

Sure. go buy a cpu pot. Go buy Ln2. Go bin chips.......the ones that suck on ln2 are usually decent on air....

[mav2000]

aaaahhhh...well thats not happening...thanks for clarifying that.

[shaolin95]

Got it Prime stable on W7 64 bits at 4118Mhz but it took some nice vcore bump compared to the 1.44 I need for 4Ghz stable though.

I should be very close if not at the limit of this one I think.


Here is a just for fun 4.3Ghz validation.

[FireDragon]

im at 4.1 at 1.525 in bios and shown in cpu-z, NB at 2800 at 1.26, 6 hrs of linpack stable at a max of 51 deg (i love my new water cooling) ram at 1720 cas 6-6-5-18-22, 16.7 sec pi 1m those r my 24/7 clocks i have settled on i can run 3dmark over 4.4 still pushing atm

[Raiderman]

Here are my current 24/7 settings. Gonna play with mem timings some more.

[shaolin95]

Very nice low voltage Raider.
Mine took a big jump to get over the 4Ghz to 4.1 I am guessing that is all I am going to get so if it does not give anything else I would start maxing out mem and nb.

[beta]

same here, 4.0 @ 1.45v - 4.1 @ 1.52v.

Raiderman, is it prime blend stable?

[crazydiamond]

shaolin how does it fair with normal ambients?

[shaolin95]

I would have to test but I never have normal temps since I either use winter cold air or connect my air duct to the ac vent on the floor next to my computer so this is my "normal" setting. I expect it to do just fine up to 4Ghz since it requires so little voltage and load temps were amazingly low compared to my 955 C2..only 33C max at the same temps I was testing the 955 (which required more voltage of course) was getting max 45C.
At the same voltage as the 955 in order to achieve 4.1, the load temps are about 5C lower so either the Gelid Extreme is 5C better than the AS5 after a better application procedure or who knows.
I would check later when I am done doing my last push for 4.2

[crazydiamond]

thx

gl w/ 4.2, i needed over 1.6vcore for 4.2 prime blend - just about a .1v increase from 4.1

[FlanK3r]

RISKA:whau, great .

[Riska]

Thanks i am waiting on the weekend to come so i can put it under Ln2

[mav2000]

Waiting for ure results...
