Post your CPU-NB frequency + voltage

[mongoled]

Hi as per title,

I have started working on my CPU-NB frequency and am looking to find data of what other peeps are using.

Id prefer peeps to post their frequency and voltage along with the type of stability testing they have used.

I am currenly testing

2800mhz @ 1.325v using prime95 blend....

[Royalk]

2660mhz @ 1.2625V primable
2670mhz Prime 95 blend I got error within several minutes, no matter how much voltage I pushed, it never got pass the test.
over 2700mhz no post at all.
C3 955 0942DPMW, not a good chip, is it?

[AlleyViper]

for cpu@3.8 cpu-nb@2.6/1.275V
for cpu@3.7 cpu-nb@2.6/1.2625V

955 C2 0911EPMW, >12h p95 x64 blend, 20 pass linpack x64 at 3072MB

[I.nfraR.ed]

965 C3 0945DPAW @ 4116MHz 1.5625V
CPU-NB 2820 1.275V
Blend stable

Makes about 3000 with 1.45V, 3050 with a nice voltage bump to 1.55V.

But I should mention that this is the chip with the best CPU-NB I've ever had!

Haven't tested thoroughly the other CPUs for NB. It's varying from chip to chip. For example, my second 965 can't handle 2.8, regardless voltage, but all others can reach CPU-NB close to 3GHz on water:

X2 550 C2 @ B50 (0925APMW)
965 C3 (0945DPAW)
965 C3 (0952GPMW)
955 C3 (0952CPMW)

[Rippthrough]

2500Mhz @ 1.245v (stock air cooling)
That's with the chip @ 3600Mhz on 1.36v and HT at 2400Mhz.

[Asmola]

2940MHz 1.4v prime blend stable, 3050MHz benchstable with 1.45v.

[crazydiamond]

2676mhz blend stable with 1.33v (not 100% positive if thats the lowest i can go on volts but its close)

[gOtVoltage]

C2 550 X4 @ 4000mhz CPUvid 1.53v /2600nb NBvid @1.32v good for 2800mhz


... The NB Multi @ 10x = 2000,,@ 13x = 2600..

Volts scale..use for C2/C3....(C2 will use +.05 to +.10v vs C3 in most cases above 2600mhz. All depends on how high the CPU Multi is Clocked with using High NB.





Older Phenoms,,
B2/B3 will use way more.

[izallica]

4ghz 2676mhz @1.35v blend stable

[Zeus]

My 965BE C3 does a mere 2.6GHz at 1.2V, 2.7GHz needs 1.35V! This must be one of the worse CPU-NB's ever. My old 955BE did 2.8GHz at 1.275V and even my old 940 could do 2.8GHz at less than 1.3V.

[I.nfraR.ed]

Nope, It's not! This one has very weak CPU-NB. I can hardly go over 2.6 with it, regardless voltage...

[RaV[666]]

Crappy 2456Mhz, stock nb volts 1.2v.This damn foxconn doesnt have any nb vid regulation ;-(

[BeepBeep2]

2612 @ 1.25v

2.9 Bench stable @ 1.425-1.45v

[afireinside]

940BE (0850 I think? launch week CPU) @ 3.8
2720mhz @ 1.425v

[Hell Hound]

Is that 24/7

[afireinside]

Is that 24/7

If you're asking me, yes.

[Hell Hound]

Air or water and how long has it been running.

[leoy]

2.8 ghz nb @ 1.25 v Piece of cake..
All the way up to 3ghz easy with 1.3v

All this all the way up to 4ghz +++ for cpu...
I must be lucky

[Shocker003]

4.008Ghz @ 1.46v CPU
2.5Ghz @ 1.275v NB
Prime stable.

[afireinside]

Air or water and how long has it been running.

Water, about a month. Spend the previous year at 1.375v or so on air. If it dies, it will be because I'm running 1.63Vcore.

http://www.google.com/url?sa=t&sourc...pt6ZwKH_IqxUAQ

Check the second to last page, says up to 1.5V on air

Nah,mines worse, it will not go over 2.5Ghz no matter what the voltage, although will run 24/7 at 2.5 with 1.245v...
Even to run the RAM at 1600Mhz it needs the NB-CPU voltage bumping to 1.325v

[Lastviking]

Got bored... is prime96 blend enogh to test stabilty on the IMC/NB?, i wonder one thing has the memmory clocks any impact on stabilty on nb/imc? higher memmory clocks lower nb clocks?

So fair 2800mhz nb @ 1.25v prime95 blend 7min+

Here comes 30min+ screen....

Funny board...sett 1.55vcore in bios give ~1.48 real vcore. This is not max mhz on cpu... only for fast nb test. ops a mistake in screen...2x cpuz same window.

[Rippthrough]

The main thing that stands out when you go through all the clocks through the forums is:

Why the bloody hell didn't AMD spec a 2.4Ghz CPU-NB frequency to start with?!

[crazydiamond]

i think people forget that we have like perfect environment for our pc's so ours are able to do 2400mhz nb on default nb volts, but some guy who lives on the equator w/ a super dusty case in the middle of july might not be able to get 2400mhz stable w/ default volts
