Overclocking Gigabyte GA-P35-DS3P with Q6600

With the R40 capacitors

sorry, i've not reply you before this.
it seems to me that the Extreme has no different compared with Turbo in some CPU FSB's and DRAM settings.
however, as far as i can recall, for 444 FSB with 4:5 DDR2-1110MHz, in order to see the performance different between using the Extreme and Turbo i need to use CAS4-4-4 and sometime a low subtimings is also required and also have to add some more volts to MCH like +0.175V - +0.250V and then i would be able to get one lower performance level at system boots. but you need to memtest and stable test your system again.

funkyfive,
can you return the CPU cooler? if so, you may want to consider returning it. and i like to suggest you do some more research before you buy a new CPU cooler.
and maybe check with Pyongmu to see if he could help you find another CPU cooler that can be installed properly on your board without any problem.

Pyongmu

Thank you PangingJr for your reply, I will experiment further with with your recommendations.

Pyongmu

Funkyfive, I am sorry regarding the CPU cooler problem. But I did not fully understand why you sough to replace the CPU cooler in the first place. The temperatures that you reported for stock settting and 400x7 were all pretty low and I was confident you could easily go up around 3400 with your old cooler. The Zalman from what I read is a decent cooler and maybe all you really need to do is a little lapping (cpu and the cooler). The temperature gain can be as much as 15 degrees! Definitely worth a try, I think.
My personal experience is that when properly lapped (both the cpu and the cooler), even the stock intel cooler, can let you OC up to 3.1GHz.

lol the rig is not real, its kinda a joke for those who know me well enough on the forums

but id imagine if i truly had the hardware, it would easily be pushed to 5.3GHz with some enhanced liquid-cooling. but die to the issues with the first batches of Yorkfield cores the clock speed to calculation ratio is off so youll lose some efficiency....

the system in general is meant to be an insane benchmarking monstrosity with that insane benchmarking price (something tells me one of the admins may actually have the machine i have listed, i think Veridian3 he seems to have review samples of various CPUs, mobos, cases and so on)



i honestly wish i could afford the system, but that would mean i need to sell twice as much stuff.... lol

Pyongmu

Thank you for straighting that out for me because I was beginning to peg you as the worst as they come: Rich spoiled kid with nothing better to do than boast that he can afford the very best on forums like this.

kris23

lol who COULD buy that at this time? X48 aint out

QX9770 aint out
OCZFlexXLC DDR3 1800Mhz aint out in even 1GB sticks let alone 2GB sticks lol

Sapphire Atomic cards are yet to be released and yea....


i aint rich.... but if i was...... i still couldnt get it.....

my REAL rig will be more down to earth, just dunno what it will be though.....

Pyongmu

I have to admit you got me good.

you yourself has a pretty powerful machine...

is that Kingston HyperX DDR2 1200mhz? thats some powerful stuff.... does it use D9GMH or D9GKX?

The ZALMAN CNPS 9500AT has already gone and i am currently running on stock again, the power of ebay. The replacement cooler has already gone back. So i am looking at another Zalman, I have been looking for one with a fan controller and can provide extra cooling around the CPU such as the cnps8700 NT/LED with fan mate2. This provides both reduced weight at only 475g and helps produce a system that is not only extremely quite on air but is overclocked as well. The biggest problem I have is that my case is tall and thin so getting a cooler that give s me the maximum air flow with minimum size is a head scratcher.

Pyongmu

I like the set up so far. It is amazing what can be done with these P35/C2 combos and I believe I have only scratched the surface!

The memorymodules are DDR2 1120's. As for the chips on the modules, I don't know if they are Micron's or something else. I haven't yet checked under the heat spreaders.

[edit] I meant to say 1150's. To better answer your question regarding the memory chips, I have been playing around with the memory settings a bit lately and found that I can go up to around 850 at CAS3-3-3-8, 1050 at 4-4-4-12, and 1210 at 5-5-5-15 at the module manufacturer's max setting of 2.35V. Based on this I am pretty sure I have D9GKX chips on my memory modules

Pyongmu

I saw a pic of an antec p182 and I see what you mean. Both the top and rear case fans are right there in the vicinity of where the CPU cooler would go... Maybe you could go with a large airy cooler in passive mode.

funkyfive

I am currently looking into termalright.

Kazeko

A good choice for air cooling, the Ultra 120 Extreme is.

Keeps my Q6600 in the low 30's at idle, mid 50's under load @ 450x8//3.6ghz, with two Aerocool Xtreme Turbine fans (Push/Pull config, 89CFM each.)

funkyfive

I got a new Zalman. Ready to give overclocking another go.

Pyongmu

Funkyfive, good to hear you’re back in action.

Before your CPU cooler problems, you wanted to know how you could speed up your memory. According to the wisdom here at DH (and elsewhere as well), your memory overclocking prospects are good if your memory modules have Micron D9xxx chips on them, but not so good if your modules don’t have these chips. So find out which chips are on your modules first.

You may be able to find this information at- DDR2 RAM List. If not, contact the manufacturer.

funkyfive

Damn mine only have Promos chips.

Pyongmu

Don't dispair. ProMOS are not as OC friendly as Microns but that doesn't mean you can't OC 'um. According to the article below, DDR913 at 4-4-4-12 and DDR1142 at 5-5-5-15 were achieved with ProMOS based modules.

PangingJr

yep, don't worry about the memory module IC's in use in your RAM, you already have the RAM with you.
so should you decide to try overclocking it, i think you should go ahead and try.
don't go buy new RAM just yet. who knows your RAM can be a very good overclock RAM as well.

Pyongmu

See how far you can go with your modules’ timing spec of CAS 4-4-4-15 first.

Start off with a low FSB/CPU at stock DDR2 setting. 333x7x2.4 (2.3GHz/DDR800) would be a good choice. Disable C.I.A.2, set Performance Enhance to Turbo, and set DRAM timing and voltage to your modules’ spec. Leave the “Advanced Timing Control” settings on Auto.

Increase the FSB frequency 4 MHz to 337. This will raise your DDR frequency 10MHz to 810. Boot to Memtest86+ and run test #5 for 20 passes. If no errors, raise the FSB another 4MHz and repeat. Keep doing this until errors are reported.

Boot to windows with the best no-error setting achived with the Memtest86+ and test for stability in windows. Prime95v25.5 would be a good choice for this test with 2048 to 4096 FFT setting. This additional test is needed because a stable memory setting in Memtest86+ is not always stable in windows. If you get errors running Prime95, back off 1MHz on FSB (2.5DDR) and try again and repeat as necessary until you arrive at the setting which will produce no errors running Prime95 overnight.

Then you can proceed with finding out what your modules can do at more relaxed DRAM timing. Set it to 5-5-5-18 and start off with the FSB/multiplier setting of 333x7x3 (2.3GHz/DDR1000). Follow the steps for the 4-4-4-15 test above with adjustments considered for the increased memory multiplier (1MHz increase in FSB will raise the DDR frequency 3MHz not 2.5MHz as before).

Happy OCing.

Pyongmu

Funkyfive,

If your OC objective is to push your system to the limits, get some modules with D9 chips and a better CPU cooler. But if your aspirations are up to say... around 3.4 GHZ, you should be fine with your current hardware.

Pyongmu

Funkyfive,

If you are still running 400x7x2 setting, try bumping up the CPU ratio to 8 for 3.2GHz. In "Advanced BIOS Features", disable the C1E and EIST functions. In MIT, keep the Porformace Enhance to Turbo, set the DRAM timing to 4-4-4-15 (press Ctrl/F1 at the main BIOS screen or upgrade to F7 or later BIOS if you don't see these setting options), DDR Overvoltage to +.3 (per 2.1V per your memory modules' spec), and CPU voltage to 1.325 .

Happy OC'ing.

Pyongmu

Once you have the system running stable, loosen the DRAM timing to 5-5-5-18 and set the memory multiplier to 2.5 for DDR1000 (you haven’t posted your memory OC results but I am assuming your modules will run at least 1000 at 5-5-5-18). Compare the results with the earlier DDR 800 @ 4-4-4-15. On my system, 2.5x multiplier (4:5 FSB to DRAM ratio) yields the best results but I have seen posts that 2x multiplier(1:1) with a tight DRAM timing is better. I suggest that you draw your own conclusions for your system.

You can hit 3.2G with 356x9 as well and I invite you to try it because there are so many memory-setting variations that are possible: 2X (712) at 4-4-4-15 timing (try 3-3-3-12 first), 2.4X (854) at 4-4-4-15, 2.5X (890) at 4-4-4-15 if your modules can go there or else 5-5-5-18, 3X (1068) at 5-5-5-18, and so on. In the end, I believe you will conclude that a higher FSB is better, but more importantly and hopefully, you have gained a better understanding on memory settings such that you will know what to do on your future OC’s.

One more 3.2G setting: 457x7 which is what I am running at the time of this edit. I had to reduce the number of installed memory modules to 2. Just can't do it with 4 modules even with +.2V PCIe and +.3V NB & MCH. With 2 sticks, I am there with "normal" PCIe, NB and MCH voltages and the memory bandwidth is better than 444x8 (3.55G) ! I am into 1+ hr of Prime25.5 and so far so good.

Pyongmu

Crashed after 4hrs (frozen screen). Raised PCIe, NB and MCH voltages to +.05, +.1 and +.1 respectively and much better: 8+ hrs on Prime25.5. The NB is running a quite a bit hotter now and to address the issue, I ordered a couple of fans for the NB cooler. While in mony spending mode, I felt appropriate to address the CPU cooling limitation of the Tuniq Tower which is currently on my system. I ordered a Thermaright U120E and a Delta 190CFM fan. I am hoping the improved cooling will let me go further.
