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!

[David9799]

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

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 :shrug:
not evryone gets golden cpu's; i certainly don't :lol: ive never had a golden cpu and probably never will either :lol2:
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 :lol:
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' :yawn:

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

[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.

[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.

I had a little experience with the Cool It Eliminator and my TR Ultra 120 extreme runs 10 deg cooler under load than that particular Water cooler. Worked Ok for my E6600 but couldn't cope with the Quad under load
Check out my post and read what others had to say in that thread Here (http://www.xtremesystems.org/forums/showpost.php?p=2272642&postcount=14). I'm am going to bet it's the Mobo. Guess you don't know anyone with a P35 board it would save some $$ to know if the chip OC's ok.

[Brother Esau]

Is that @load I assume? @3.0GHZ I idle @30-32c highest cre in core temp underload I usually get around 62-64c highest core same clock.

[mariniam]

No thats at IDLE but thats the mobo reading from the bios.

@3,0 I idle 44C highest temp in coretemp, thats with stock voltages. Under load im around 63C with these settings.

[jkresh]

mariniam what waterblock (storm, apogee, apogee gt/gtx), also what radiator and are you sure you have a good mount?

[adamsleath]

my BIOS reading is also very high vs all the other temp reading programs.

my BIOS temp is a total crock atm. 50C or thereabouts at idle...and thats just bollox. my heatsink base is also cool to the touch :shrug:
but yeah since ive been mucking around:
1st remount: idle at 43 ctemp
2nd remount: idle at 32C ctemp (2 screws on the diagonal only)
3rd 'remount': idle at 21C ctemp (4 screws all tight!)

the mount pressure had a huge effect.

could be worth a quick check of the waterblock mount....but youve probably already done that properly. :shrug:

Maybe set PCI-e frequency to 101mhz? Boards may not lock it when left at 100mhz.

[SLINROB]

unfortunately that will not have anything to do with helping the cpu overclock.

[mariniam]

It's the swiftech apex ultra kit with the apogee GT block. When I mounted the block I tightened all four screws tightly. So the mount should be OK, maybe I'll give it another go tomorrow though.

Thanks for the suggestions guys.

Well I just passed a 30min stress test with OCCT @3,2 on stock volts. I know its not enough to prove the system stable but its a decent start. Just want to see how high I can go on stock. Max temps were @ 68C at one point.

[alexio]

unfortunately that will not have anything to do with helping the cpu overclock.
The PCI-e bus is connected with the FSB, so it does. 311mhz FSB / 267mhz (stock) X 100mhz PCI-e (stock) = 117mhz PCI-e. It's unlikely that the GFX card can't handle this, but it puts a higher stress on the chipset.

SATA bus is connected to the PCI-e bus and FSB. If the PCI-e bus is not locked, then the SATA might not either. SATA devices are extremely sensitive to frequency changes.

This is all unlikely to cause the problem, but if you have nothing else left to try....

It's most likely the motherboards, so I'd try anything in that area.

Might just hold out on that P35 board mate...

I got a shcoker too. Same steppings, using Gigabyte P35-DS4 board...

Get constant reboots/freezes when i try anything between 270-300fsb, no matter what volts I may be running thru it.

Temps are also thru the roof as well...

I have an older (1st gen) Asetek watercooling kit as well as a Gigabyte WC kit as well that I might have to dust off.

Either that, or just throw this CPU in bro's PC & stick to my old E6600 (not best OCer but could OC none-the-less)...

I think anyone that buys a quad core should make sure they either have 2 things with them.

1.) List with all the G0 steppings
2.) ability to have look at boxes available to make sure they are getting G0.

Not that it helps any in Australia. We always get the shoddy ones unless we buy direct from overseas or from known seller......

Anyways. Gonna give this POS CPU another day or 2 b4 I just call it a loss & give it to my bro.

Next time I buy one will be a while away. When I know that we aussies aren't stuck with the B3 POS ones...

I run my pci-e at 125 and have been up to 130 389fsb x9 for 3501mhz. It takes a little over 1.5v actual to get it stable in 3dmark06 and nuc2.0 i've never run orthos. I run 334x9 at 1.35 actual for daily use.

I currently run my B3 Q6600 @ 3200mhz using auto voltage on P35-DQ6. I am using Thermalright Ultra (not extreme) @ around 32-25 degrees C on idle.

I am running 1:1 with Kingston hyperx 900mhz @ 800mhz. I really wanted to run @ 1:1 :D

[Vienna]

I haven't tried any higher than this but...

My B3 stepping, Week L644, is mosty stable(i.e. long as the fan thats focused on my ram doesn't fall off/turn off) at 3.2GHz @ 400x8 FSB, RAM 2:3 ratio 600MHz 5-5-5-15 with load temps of 75*C on Core Temp 0.95......

STOCK COOLER, yes I know, surprised the :banana::banana::banana::banana: out of me when I did the same with my friends new quad G0 stepping, let alone my B3. Load temps are high, and while I can run core 1+2 or 3+4 or 2+3 or 1+4 or any other cobanation, the second I load more than 2 cores, one of the cores fail (the rest keep trucking) so right now I'm limited by heat :( Can't wait to get my watercooling in in that case :D

FYI - I have a P5K vanilla board with Volts at 1.400 in bios, 1.275-1.295 under load (stupid vdroop), so it may not be your cpu, wait till you get a P35, maybe you'll have better results

[strange|ife]

dont worry man, some people got duked with the G0's

mine just will not remain stable past 3.48..iam able to boot at 3.8 lol..with some serious vcore

still on the fence about sending in for a diffrent one...damn canada!

[fallwind]

I ordered 2 Q6600 B3's for my folding farm, both were the exact same stepping, week, even the serial numbers were very close. One does 3.4 at 1.4v(bios), the other does 3.0 at 1.4v, both on water and both OC's were temperature limited. So even chips cut from the same wafer are highly variable. It's luck of the draw with these.

I have a G0 on it's way, if it can't beat my QX6700 at 3.5GHz I'll toss it in my girlfriends DS3 air-cooled rig.

The P5W DH acutally did better with the quad i have. The Striker would not even boot up when i went past 2.8 i would get memory dump blue srceen of death on boot. P5W would boot but then give me lockups and a memory blue screen or simply lock up.

I think i may just have a crap Q6600. Even at stock settings on the P5W DH i get random lock ups (no blue screen) i don't think a CPU could cause this? On boot up i notice the screen looks funny for a sec. I have seen this before on doing a OC thats not going to work.

Any suggestions on this? I'm pretty mush back to my old setup only things that are differant are the

q6600
new PSU
new hard drive

seems to only hang when i mess with my antivirus.

[MKM]

I think anyone that buys a quad core should make sure they either have 2 things with them.

1.) List with all the G0 steppings
2.) ability to have look at boxes available to make sure they are getting G0.

I've ordered a Q6600 in Sweden and as I can send it back if I like and get all my money back (except for shipping costs) I'm planning to keep ordering them from different places until I get a G0.

So, should I basically look for boxes with L723 and higher as those have to be G0 (Tiramisu's Q6600 was L723A765) and send it back if it's lower or where can I find a list with the G0?

[Minnyboy]

U can find specific sPec numbers here:
http://processorfinder.intel.com/

there is only 2 that I can find for the Q6600.
SLACR = G0
SL9UM = B3

I did a bit of testing today with my Gigabyte P35-DS4 & Q6600.

It seems as tho this board is very picky with the speed of the PCI-E lane. I have had it set at 110-115 all the time with my last E6600 & thought that it would not make that much of a diff if any, as long as I went over 101mhz for the PCI-E lane it would be fine.

Guess not.

Started by leaving everything else cept for mem volts/timings, fsb volts & NB volts & "locking" the PCI-E lane to 101mhz. Then I went & just tried upping the fsb bit by bit & testing it out with P95 + 1hr 3dMark06.

So far so good for me now. Nothing special but WAY better than i was at the other day where anything would crash it & I needed extreme volts (for air anyways) just to get somewhere.

Now testing at 333fsb with 4:5 divider on RAM & Cpu volts at 1.3125v (default is 1.2875v)...

Gonna push it a bit more now since it is looking ok.

Still thinking bout taking this CPU out & sending it to my bro & getting another one; this time making sure it is G0...

Temps are also a LOT better since I don't need to shove alot of volts to fsb, nb & cpu...

Anyways, i'll update this when i have finalised testing... Back to WOW for now :p

I think I lost me Xtreme-ness, I'd settle for that 3.2 at those temps and be happy as hell.

To the other guys, I'd take Intel chip sets over nVidia or ATI's any day of the week. Lock the danged PCI-E bus to 100/101 and loosen the RAM timings. Tight timings only truly makes a difference on benchmarks. These low settings also limits overclocking=P These aren't AMD processors LOL! Smart Cache and Smart Memory access limits the effects of slower timings anyway.

Also keep in mind that just about every feature the Processors has can affect overclocking. Disable some or all of them to check. Please go back and carefully read the sticky that address setting these issues.
