Sorry about image sizes, i don't have photoshop installed yet.

I'm tired after a long day and many beers, so I'm going to bed but I thought I'd bring you this to tide you over until tomorrow.

4ghz was a snap

Heres hwo the voltages went.

FSB - Core Voltage
300 - 1.32
333 - 1.32
366 - 1.36
400 - 1.40
420 - 1.42
433 - 1.5
450 - 1.58 = 4.05Ghz (ram bumped to 2.2 from 2.1)



Rig (will update sig soon!)

cpu - q6600 g0
MB - asus p5k premium
RAM -2*1gb 8500 Corsair Dominators
VGA - saphire 2900xt
HDD -10k 74gb raptor
PSU - 850W modular Silverstone

cooling (15-20 idle)

D-tek fuzion 1/2"
GTX 240
MCP655
Lots of fans.


Note Only the CPU is overclocked, the 3dmark06 run is with stock 2900xt settings.

The CPu probably has more to go as well, to tired ot push it further tonight. but voltage is @ 1.58, Im confy with at least 1.6v so i will set it to that tomorrow and the ram to 2.4v and see how far she goes.

4.2, 4.3 maybe?

Then OC the radeon and crack 15k in 3dmark06 i think

[CGR]

Not bad, but have you stress tested it for at least 15 hours on each core?

[nikhsub1]

Very nice, reminds me of the end of the Prescot era...

[dominick32]

Exactly, there are many threads lately about 6850's and q6600's at 4.0 stable. But no orthos or prime screenshots displaying long term stability.

In any event. This is a great overclock! Congrats. Keep us posted.

[AngryArtichoke]

Great job! I am curious how long you can run orthos so you stress it at 100% though.

[Phrenetical]

Patience is a virtue boys. Its far to late to run stability tests, its like 3.15am right now.

Tomorrow after i figure out how far she goes, i will find her stable points for 3dmark06, superPI, then prime95.

Orthos not to keen on, Prime95 has always been my fav.


BTW

temps were 32c idle and loading during 3dmark06 was 45c, i ran prime95 for about 5 seconds and one core was at 50c while the other were at 47c.

One core is way hotter then the rest, 2-3c higher everytime. it reports as the second temp with coretemp, is coretemp temp readouts relational to where the cores are on the die? As im wondering if one of the d-tek bolts isn't tight enough on one of the corners.

night..

Essentially 16GHz effective for Alan Wake!!!!

[Dawgdoc]

I have a very simliar setup (no WC though, TRUE 120), but the same proc, mobo, etc...

Could you post pictures of your BIOS pages, or at least give us a rundown on all of the different settings on all of the BIOS options?

Would be a great help to me, and I am sure others.....

Thanks!

[Sir. BOBSONATOR]

very nice mate.

[ShadowPho]

Nice!
Who ever said that you can only get 3.6GHz on the Q6600?

[Albaholic]

All you guys making me wanna upgrade to a quad. I was going to hold out till penryn but........

[Cyrix_2k]

you guys are making me catch the upgrade bug... but I don't have any money Nice job on that overclock!

[Phrenetical]

I'm awake, this proc is gonna get hammered today.

@dom - Oh yeah baby, and 16ghz fro crysis and Unreal Tournament 3, and i hear the new photoshop will be tweakedfor quads

@Dawgdoc - My bios is almost exactly the same as the http://www.ocforums.com/showthread.php?t=515316 sticky

That sticky will give you all the info you need for clocking your quad and bios settings. All i can say is make sure you have the latest coretemp BETA, as the stable release crashes your rig for quads.

I actually threw coretemp into the startup folder, and as soon as the pc was logging into windoze it would restart back to bios. I thought It was busted, turned out to just be dodgey software though, bloody coretemp...

@ShadowPho - blasphemy

@ everyone else - its not over yet, this cpu has a bit more left in it. More screenies to follow


I think he's wanting specific BIOS settings.

Can you fill this out?

Alrighty who can help me with northbridge settings.

The ram doesn not want to go over 450, cant even get to windows at 455

bumped cpu core to 1.625, ram - 2.4 still no go.

Maybe its the northbridge? I have no experience OC'n the NB, what are the default volts for it on a p5k premium?

And should i be setting a Northbirdge fsb strap? At the moment its on auto.

Any help is of course much appreciated. I definitely want a few suicide screenies at 4.2

[aaronjb]

That's a great overclock indeed. I run mine daily at 3.6 Ghz, but I'd love to push it a bit higher.

Thank goodness for fall weather and cooler temps!

You could be maxing it out .. not sure though.

Did you test to see if you could get 4.GHz stable? I would'nt go any further until you can get it stable ...

My e6750 maxes out at 510 FSB (4.1Ghz) ... maybe you have hit that point ...

[Phrenetical]

probably, but it gives me hope i can run ram at 4-4-4-12 as it is still way under its rated max.

currently 450, they can do 533 @ 5-5-5-15 pparently anywway

[jason4207]

Try dropping the multi, and seeing how high you can get the FSB while messing w/ all those voltage settings besides vCore, and vDimm.

You also have your DRAM freq set to auto. Are you sure you're running 1:1? What does CPU-Z say?

Here are my BIOS settings, and some notes I took. Keep in mind my quad has a max multi of 8. My max FSB is 480 (CPU FSB wall). I may be trying a 1333FSB pad mod soon to see if I can get that max FSB up a bit.

JumperFree Configuration Settings
AI Overclocking: Manual
CPU Ratio Control: Auto (manual for testing)
- Ratio CMOS Setting: 8
FSB Strap to Northbridge: 333 (Auto works fine)
FSB Frequency: 450 (Max is 480 for me w/ multi at 7)
PCI-E Frequency: 100 (110 didn't allow any additional OC on GPU)
DRAM Frequency: DDR2-900 (Ended up at 1:1 after benching several other ratios/timings)
DRAM Command Rate: 2T (1T wouldn't boot, more voltage maybe?)
DRAM Timing Control: Manual
CAS# Latency: 4 (3 wouldn't boot, more voltage maybe?)
RAS# to CAS# Delay: 4 (3 wouldn't boot, more voltage maybe?)
RAS# Precharge: 4 (3 makes memset lock-up)
RAS# Activate to Precharge: 8 (6 worked, but random issues have made me go back to 8)
TWR: AUTO (auto gives optimum setting based on memset testing)
TRFC: 25 (25 is best)
TWTR: 3 (shows up as 10 in memset [skewed])
TRRD: AUTO (auto gives optimum setting based on memset testing)
TRTP: AUTO (auto gives optimum setting based on memset testing)
DRAM Static Read Control: enabled (provides higher bandwidth)

Transaction Booster: Disabled (Enabled provides better bandwidth, but it isn't stable)
Boost/Relax Level: Level 0 (Higher relax level reduces bandwidth)
Clock Over-Charging Mode: 1.000v (had on AUTO, but higher FSB speeds demanded 1v. I may be able to turn this back down a bit for 450)

CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled

CPU Voltage: 1.5125v (anything lower gave me core failures after 1.5-2hrs. 1.6v allowed 3.8GHz, but I think a little more is needed for P95.4 stability)
CPU Voltage Reference: 0.63x (I wasn't getting much over 3.2GHz until I changed this from Auto. 0.57x, and 0.59x wasn't stable. 0.61x worked, but I have a feeling 0.63x is best.)
CPU Voltage Damper: Enabled
CPU PLL Voltage: 1.60 (I may be able to reduce this to 1.5 for 450FSB. At 480FSB 1.5-1.6 [or 1.7?] wasn't stable, 1.8-2.2 worked.)
DRAM Voltage: 2.15 (2.3 was used to ensure stability through testing, but 2.2 should be fine)
FSB Termination Voltage: 1.30 (1.5 for 480FSB, I may be able to go lower at 450)
North Bridge Voltage: 1.4 (1.8 for 480, anything higher is actually worse)
North Bridge Voltage Reference: AUTO (0.67x for 480FSB, auto seems to work best for 450)
South Bridge Voltage: 1.05 (I had it at 1.2 during testing to ensure stability...don't know if it helped)

Advance CPU Settings
CPU Ratio Control: Auto (manual for testing)
- Ratio CMOS Setting: 8
C1E Suppport: Enabled (disabled for testing)
Max CPUID Value Limit: Disabled (I just left this disabled, I don't know if it hurts or helps)
Vanderpool Technology: Disabled (I just left this disabled, I don't know if it hurts or helps)
CPU TM Function: Enabled
Execute Disable Bit: Enabled (Not sure what this does, but I've seen others w/ it enabled)
PECI: Enabled

I'd put your RAM at 5-5-5-15 for testing purposes just so you know they aren't getting in the way.

[Phrenetical]

Will tweak bios soonish, so far so good on stability testing

Prime95 4 threads + general use = 40 minutes no errors so far. I will let it run for another hour or so and call it semi-stable

@4.05ghz - 450fsb even 1.6v didn't get it stable in prime, but i played UT3 for 20 minutes without issue at that speed LOL


@3.89Ghz 1.58v - 433 FSb - 1:1 dram = 2.2v (1732 fsb) = 40 mins stable in prime

Max temp so far on only one core is 57c. the others are all at 55c.


maybe 433 is a sweet spot for the board/ram, something to do with strappings maybe.

-----------
edit, 1 hr stable @3.89 Back to other benches.

will put up screeny soon as i get Photoshop installed :P

[SuperMiguel]

i changed few things like that i read i a earlier post i dont know if this is good or not thanks:
Vcore = 1.55v
CPU PLL = 1.8v
NB = 1.730
DRAM = 2.2v
FSB T. = 1.6v
SB = 1.175
SB 1.5v = 1.850

are they any good or is to much?? what should i do to make a 4.0 stable it i not stable at all

I think your gonna need at least 1.6 - 1.62v vcore, and the NB voltage seems WAY high ...

[Phrenetical]

Screenies of stability testing and OC

bios = 1.58 volts

@ 3.89 i ran those primes for 1hr 10 minutes, and have been using the computer all day to play UT3, and install, browse, run apps etc...

Oh and the dominators are now @ 4-4-4-12, no issues!

I think 3.89 will be my daily setting unless this summer has something to say about it.

ANyone see any issue running 1.58 @ 3.89 daily?

Remember this is water.

tmps are - 30 idle - 55c 4 core 100%

[MadMan007]

You can test your NB voltage and max FSB by using a low multi and isolating the NB and resulting Ram speed from the CPU core speed. Quite the nice oc there, what batch and VID is your CPU?

btw you can resize pictures in paint

[Dawgdoc]

Whats up with your Cpu-z? Is it buggy? Perhaps it isnt as stable as it seems?

Which P95 test did you run? Small fft, large fft, or blend?

[Phrenetical]

large fet i think, and what do you mean about cpu-z?

it looks strange because th image was resized in paint to be under 200kb

[jason4207]

All the outlines in CPU-Z are gone in your pic. Probably due to you compressing it.

You should be using small fft to stress the CPU. Large fft stresses the RAM.

You say you have 1.58v set in the BIOS, but CPU-Z shows only 1.48v actual voltage. Do you have Voltage Damper enabled in BIOS? I ask b/c I have 1.5125v set in BIOS, but CPU-Z shows 1.488v for me.

Make sure to enable Voltage Damper in BIOS. It is one of the best reasons to buy this board. You should be able to reduce your vCore after you do that if you want.

[Phrenetical]

k will give it a go still playing with everything

image 1 = 3dmark06
q6600 @ 4.05Ghz 4-4-4-12, 2900xt @ 850/925

image 2 = Pi 1M
q6600 @ 4.05Ghz 4-4-4-12


Are these good or average?

[toddm27]

nice results , as far as the board limits, I'd try dropping the multi and seeing what the chip is capable of at 6x or 7x,
looking pretty good, if you want a good comparison, drop by the benching section to get some ideas, and you might want to update that superpi to version 1.5 to give you more acurate comparisons
