Got a crap OC with Q6600

[David9799]

I bought a Q6600 B3 SL9UM

my best OC is 2.8! pretty sad.

Used the striker extreme and P5W DH both boards got it to 2.8.

Even tired a few suicide runs with vcore over 1.6v it still was not stable above 2.8

runs fine at 2.8Ghz on AIR vcore 1.35 memory at 2.2v. anything above that and it hangs up on the P5W and on the striker it wouldn't boot.

Something is holding you back and I dont think its the CPU.

Whats the Pack Date and Batch # because mine is a dog too!

Like what? I played with all the settings in the bios it didn't matter how high i had the volts still would not be stable above 2.8

i messed around with the

HT Voltage
NB Core Voltage
SB Core Voltage
CPU VTT Voltage

Spread Spectrum Disabled etc etc

Its just strange how 2 differant MB got about the same results so thats why i think its a crap Q6600.

David,
Have you tried dropping the multi to see what you could boot at. Also what temps are you getting (coretemp) at 2.8? While neither the p5w or the striker (at least before the newest bios) were that good at quad overclocking you should be able to get above 2.8.

[adamsleath]

temperatures at load? i bet it's getting hot especially @ higher voltage when it is failing.

[David9799]

when at 2.8 it got up to 58c going by coretemp

I had it over 2.8 but even with insane high volts it was not stable 3dmark would hang or give me the blue screen so i never really got far enough to get anytemps.

[adamsleath]

oh...well its not temp then is it?...assuming ctemp reading is accurate.

maybe you are right and it's your chip
not evryone gets golden cpu's; i certainly don't ive never had a golden cpu and probably never will either
is tjunction 85C on q6600?
u might have more luck with a p35..then again u might not.

FPO/BATCH #: L721A338 B3 Stepping (vid) 1.3250 7/11/07

I'd say that 3.2ghz is the top end with mine and requires too much jump in Vcore and temps to justify 200mhz

[mariniam]

Just go my new Q6600 installed on P5K Deluxe with swiftech water kit.

FPO/BATCH #: L719A424 B3 Stepping (vid) 1.3250
Room temps 22 - 24C
Core temp IDLE:
Core 0 43C
Core 1 43C
Core 2 39C
Core 3 40C

Should I even bother OCing this chip since I can switch it with another one for free from were I bought it?

[adamsleath]

dunno why not test it then swap it...
but i see your logic.

You might be spot on with suggesting a P35. My B3 Q6600 would boot at 3200 with the P5W DH but was not stable no mater what I did. Thought it was the chip but the P5K Deluxe proved me wrong and it now goes to 3.7+. That's as far as I have pushed it. The P5W DH board works great for the C2D but obviously has issues with the Quad.

[mariniam]

Thats great news, 3.7 is awesome! Is it stable at that?

I hope mine gets that far.

Yas actually but it ran pretty warm while I was stress testing 65 deg (cores) I won't even try it again until winter arrives or at least cooler weather.

[mariniam]

Really? Im running 60C as we speak while testing 2,7 on stock volts. This has to be a sh@t CPU.

But aren't the Quads supposed to be OK up to 75C since they normally run hotter than duos?

[adamsleath]

dont worry until you get to 85C
no; but seriously anything less than 70C should be fine (i think) full load max in summer ie.

for sure quads should run hotter. 65c at full load is ok imo. 70+C starts to worry me.

ive had orthos running at 70-75 for ages....so long as the cpu can handle the volts/speed - i dont think a cpu near its oc limit will be very happy at very high temps tho'

all i can reasonably get from this 6850 is 3.6...not really happy running 1.52+ volts just to get 3.7 stable

[crossg]

I am not positive but if you go by Intel Specs the B3 is around 62C and the G0 is around 70C but I don't think a lot of people really care. Seen some up in the 90C area and if it's not throttling I guess it's good for them.
My first OC with the P5W DH Deluxe with a Zalman 9500 Cooler. Click
P5K Deluxe an Antec 900 Gamer case and a TR Ultra 120 Extreme cooler Click
I have another screenie @ 3654 under load somewhere on this forum and the temps were right at 60C.

Edit: Found it 3654 Mhz

[mariniam]

Christ! Im getting 63C at 3,0 stock volts testing on OCCT. I wont even be able to up the vcore latter on at this rate and I've got the damn aircon running in here.

60C @ 3654 he says...

[adamsleath]

a better cooler on your cpu sink maybe...

but i have noticed that as soon as ctemp reads >85C orthos fails like clockwork. BUT: my tjunction is 85C.
i notice by crossq screens that the kentsfield q tjunction is 100c - i think that makes a difference re 90C type temps being ok....so the quad vs my dual seems to have 15C extra to play with anyway.

and in any event 1.35-1.5v is all you should need to achieve a good oc
its up to you whether to try a new mobo or another lucky dip with another cpu...

[mariniam]

Thanks but Im using a Swiftech water block so I should be sorted.

So which program to trust? Some are using coretemp and others speedfan.
My speedfan shows exactly 15C less than coretemp/everest on all cores but I don't think thats reading the tjunction of 100C correctly.

[Brother Esau]

My chip runs hot for my cooling at high volts but I really believe that it can go higher but this EVGA 680i A1 probably aint worth a sh*t for overclocking Quad Core! Although on C2D i can run stable at 475 FSB all day with that said what do you guy's think? Processor or Motherboard which do you think is the culpret?

[adamsleath]

what about your bios temp or TAT?
@ first all my temps were diffrent now they all read the same ...

if u are on water maybe your 63c reading is wrong...? who knows i aint got a quad.

when i first put in the 6850 ctemp read 11C lol; now its back to 21C...@ idle; if i take 2 screws out of the tuniq and reduce mount pressure, the temp rises by 10C

ive never had waterblocks; do they get warm (to the touch)?

[mariniam]

Bios is 33C for CPU

No they don't get warm at all. Mine is actually cold when I touch it.

I just checked a thread eva2000 posted where he had a Q6600 B3 ES CPU and his coretemp temps are almost identical to mine on stock settings. So I guess I shouldn't worry too much. But still don't know what program to trust 100%. If you are right about the extra 15C head room then things aren't all bad actually.
