My question is that I see to be hitting some MHz barrier BUT it doesn't make any sense at all. Let me explain...

I ran the FSB at 133 (266DDR) to single out CPU performance.

1st: I hit 1.866G at 1.35V - nice...

2nd: I hit 2.0G at 1.45V - Going strong...

3rd: I hit 2.2G at 1.55V - (1.65 is standard voltage at this speed from the factory) - Still going strong right? I'm thinking I've got some kind of OC champ...

4th: I hit 2.4G and crashed.. over and over again... - I tried 1.6V, 1.65V, 1.7V, 1.75V, 1.8V and all I keep getting is that black screen BEEP and lowBEEP, BEEP and lowBEEP where I have to unplug the PS and pull the battery out of the Mobo to reset the BIOS.

5th: (now) I'm running at 2274 at 1.65V (207*11 which is in my sig).


I can't figure this one out... I have an NF7-S, TruePower 550W, CoolerMaster AERO7+... I even ran these test with the case open and a fan blowing cool air. So I should be good to go right? Any suggestions, even if you think I've already tried them, would be GREATLY appreciated!!!

what's the problem then? you never really say what you want it to do or what you think is wrong.. just do 200 mhz fsb and set the vcore to 1.8 and see how far it goes..

this one 35 watt processor doesnt like speed greater than 2133 mhz . so far this is the only stable speed for it. i tried 2300mhz at 1.65 , 1.72 and up to 1.77 . prime will work for a short while then computer will reboot . blank screen after that. i have to shut down and reboot then it will load windows again. my other 35 watt processors have had no problem working at 2300mhz with right cpu voltage
this processor just doesnt want to oc very well

What you need to do is pull out your chip, bend thermistor (thermal diode) upwards to 45 degrees from mobo plane. High enough so your chip makes contact with it upon reinsertion and is touching it. It's allright if you use the chip upon re-insertion to push it back down too so long as it stays in contact with the chip. this will fix your problem.

 

[RetailDirect]

Thanks alot Zebo! I will try that and post the results... Northface, my problem was that I was expecting a higher clock speed from this chip and the way it was working up to that point indicated it would go much higher. (It went from 2.2GHz @ 1.55V to crashing at 2.4GHz @ at as high as 1.85V)

 

[Zebo]

Ya it sounds like you have a nice chip easy 2600Mhzer, turns out when the Thermal Diode (blue thingie in the socket) isnt making proper contact with the CPU, it causes the siren. Depending on how badly seated the diode is, changes to the higher V-core and it craps out. But this will fix it.

 

[RetailDirect]

Yeah Zebo! Great info on that one! Anyways, I am now up to 2.5GHz @ 1.875V (12.5*200). I'm gonna see how stable it is with some prime95 overnight. BTW - I have a Coolermaster Aero7+ which is all copper and very highly rated but I wonder if 1.875V is too much for long term?

Also, there is another concern... I recently purchased two seperate (from different people) 512 sticks of Kingston BH-5 (to run in dual channel). The problem is that one stick is pc3200 while the other stick is pc3000. Also, the pc3000 is the Kingston restamped Winbond modules (dw-50 I believe) while the pc3200 has the regular Winbond stamping with BH-5 labels. I have tested each module by themselves and found out that @ 2.9V and 2-2-2-11, the pc3000 goes out at 210-215 and the pc3200 goes out at 220-225. I'm wondering if there are any conflicts between these modules while they are running dual channel?

 

[Zebo]

I'm REALLY surprised you need that much voltage. Is this what CPUz's telling ya or bios? (I hit 2.6 and 2.7 with less than 1.8. And they do 2.5 on 1.65. lucky? I doubt it)

Try some lower cores and be sure bios is set correctly IE:

settings abit nf7-s
-----------------------------

AGP Transfer: 8x (if card supports)
AGP Fast Writes: Enable. (if card supports)
IR: Disable unless you need
SATA: Disable unless you need
MIDI: Disable unless you need

Disabled everything with a % sign

Later when chip stableizes tweak memory to 2-2-2 in progressive steps. And you only need about 6 min of prime 95 while doing initial CPU testing. after finding sweet spot then a couple hours. Take notes!!!

I need more info on that ram before saying anything. What's the exact on chip lables? I believe all KHX non a verisons are BH-5. Oh and generally expect less than single channel performace with two sticks, but no conflicts.

Might have to do with the mainboard. On my AN7, my 45watt I-stepper maxed at 2420 with 2.0volts. Now my new 35watt I-stepper is maxing at 2556 with requiremenet of 1.94volts. They're definitely higher than what you've gotten on your NF7, but not out of line with his results.

I'm starting to think 2600+'s are the way to go.

i've only gone through 4 of these...

a 2600+
a 2500+
a 2400+ 35w
a 2400+ 35w

all have been capable of at least 2.5 ghz on air with 1.85 volts or lower...

IMHO, they are all about the same...

 

[EddNog]

As I said, more likely something to do with the board, but I'm not sure exactly what. Right now I'm looking at 46C idle and 56C load temps with an SP-97 and a Panaflo M1B @ 12volts for the 35watter at 2556 and 1.94volts. I tried to go lower but instability sets in.

OMG 1.85?!?!??!

So? all mine (2) do that with 1.65

= bettar

= teh 2600+

 

[Shimmishim]

eh, who cares about air when you have phase change...

= 3.0 ghz

= better than your 2600+ @ 2.5 on air

I WIN!!!

 

[Zebo]

Well I'm 2.7@1.81 on h20 so there

 

[EddNog]

Well, my point here is that everyone so far has gotten consistent results in terms of power hungriness of the chips on a per board basis (i.e. I need approx. 1.9-2.0 to get the most out of my Mobiles on my AN7, he needs ~1.85 for max out all his Mobiles on his NF7-S, you need only 1.65 for both your Mobiles on your board); somehow, I say once more, I get a feeling it's somehow board related.

I only wish I knew exactly what/why this is occurring (sic?).

OMG H2O was SOO last year...



2.7 ain't too bad on water.

someone has one at 2.8 on water.

have you tried more voltage???

considering these chips have a max voltage of 2.15.

i'm sure you could get at least 2.8 if you tried 1.95 or so volts...

DO IT DO IT!!!

squeeze out the last bit of speed from these babies!!!

Feable reply I know...

I was off I'm at 1.78 Vcore but 1.85 in bios///

naw my systems not about performance..it's a bonus sure, but I have no fans in my system but a PSU fan. Passive innovatek rads can't handle no more Vcore along with Video card.. but I like silence.

 

[RetailDirect]

I think I am having thermal issues. Under full load (200*12@1.85V) I am topping 68 Celcius. I'm pretty sure that isn't ideal... What are you guys running temp wise at full load? What is acceptable?

In regards to the voltage issue... It is quite strange to have 2.2GHz @ 1.55V but then I have to take it up to 1.85 just to keep 2.4GHz stable. - Any ideas on this one?!?! Because, if it was the board (NF7-S) it wouldn't have run 2.2GHz @ 1.55V... right?

 

[Zebo]

Very odd.

What HS and fan RD? scrath that just saw aero 7...

Yes that is a bit high. Sure you put HS on correctly with the notch on the proper side? I'm sure you did cause you sound experianced but I make this mistake still sometimes.

Also is your board undervolting at all by CPUz's numbers?

 

[EddNog]

I don't mean by board model; I mean by individual boards. There are always variances from piece to piece during manufacturing (like any other thing in the world that's mass-fabricated).

Your temperatures do sound quite high; as I said, I'm looking at idle of 46C and load of 56C with a Thermalright SP-97 and a 92mm Panaflo M1B (avg. speed 2450rpm). I have pretty large amounts of air flow what with a Fortron FSP300-60PN modified with a Globe 120mm thermal fan and also an AcoustiFan AF120CT at the case exhaust; no need for an intake fan at all. In fact, I can easily feel the air flowing in when I pass my hand over the front intake.

Actually, if you want to see my Barton machine, it's called Gamma-Two, and you can find it either over here at my web site, or over here at the SilentPCReview forums; I'm a hardware reviewer for SPCR.

Btw, if you haven't visited SPCR yet, I heartily recommend it, even if you're not interested in silencing your PC at all (which I doubt, there's got to be at least some interest ), I am confident you will see that we have some of the most in-depth PSU and HSF reviews on the web. Also, if you have time, stop by my own web site. It needs a tiny bit of updating, but it does give you a general idea where I'm coming from, if anybody's interested.

Real nice job and clean.

I go there all the time to read reviews. Mike, you and ralf post some of the best on the net, detail #1.

3.0 with XP mobile. Wow! Heck of an overclock no matter what cooling you use.

 

[Gamingphreek]

Lol wow is right that is (3.0Ghz) the max clockspeed for AXP processors.

[Zebo]

3.2 is about the best I've seen on mach II's over at xtreme and other places.

 

[EddNog]

Thanx, Zebo!

But yea... considering some people are stuck at 2.4 and some people get up to 3.0 on phase change, I'm actually pretty happy with my 2556 with air cooling (without the need to use my 92mm Vantec Tornado; that thing is vicious! :Q).

 

[RetailDirect]

I finally got it stable @ 2.433GHz (211.5*11.5). Thanks to the advice from you guys in here! One interesting thing I noticed is that while I have the VCore set in bios to 1.85 it is actuall running 1.79-1.81. Yet the DDR Voltage is set at 2.9 yet runs at 2.93-2.95...

Running Prime95 heat test I hit 68.5C, so I probably don't need to raise my VCore any more than I have already... even though I would like to be running with you guys in the 2.5-2.6 range. I think I need to jump on the water cooling bandwagon or even just get a cooler case. I have an OEM style white case with ONE 80mm Intake fan, but I do have a TruPower 550 and a VGA Silencer that helps push out alot of hot air but my case temps still top 45C. What CPU/Case temps are you guys running?
