Retail Q9650 Overclocking Thread

[TooFastForYa]

I just tried upping the vdimm to 1.94 and that gave me a bsod when I ran prime.

[Hoss331]

You are using the low voltage ram, right? If so and its not even booting up at rated voltage and slower than rated speed you might want to run memtest first. Clock it down to a know stable speed with ram at 1200 and run memtest, you may have a bad stick.

[nkresho]

Now I might be having second thoughts about the lv 9600 ram I was going to get.

I was holding my finger above the buy button on those tridents all day today.

[KRich]

Hoss, tried that template. Wouldn't even boot with 1.8 vdimm. Upped it to 1.9 and booted. Failed prime after 2 test. Temps look good however. Here is a screenshot. Three of my cores don't read under 37 as you can see. One that does read 27C at idle.

I get the 'Prime95 Application Error' when VCore is too low, but not low enough to cause a 0x000000124 BSOD.

Try increasing VCore a few notches and see if it removes that particular error.

[nkresho]

Well 4250 proved stable last night. Any help on lowering my core voltage would be greatly appreciated.

[TooFastForYa]

Yes, I am running LV ram. I will clock it at something low and test the memory now and report back.
Thanks guys.

Here are the results. Ram looks good. I have the vdimm at 1.9 though. I'm going to lower it now and see if it's still stable.

[TooFastForYa]

Wouldn't boot with anything less then 1.86 for vdimm, however I have gotten an error with memtest @ 1.86 so would prob be stable with a min of 1.88.

[TooFastForYa]

I don't know what the deal is.
Failed prime after 10 minutes.

[Hoss331]

Test each stick individually at 1.80/1.82, if they wont pass at there rated voltage and stock speed id rma them.

[OC Nub]

Try 480x8-250a for 3840mhz cpu, this will also put your ram at 1200. If that passes then try 480x9-250a for 4320mhz. I cant boot with certain dividers with my OCZ LV Platinums. I also agree with KRich, not enough vcore will cause prime to stop responding.

[OC Nub]

GSkill f2-9600CL5D-4GBPI ordered. I hope it is good. I hate paying this price for ddr2.

[nkresho]

^I just ordered a set of the OCZ blade low voltage ones.

Link

2x2gb 1.8v 5-5-5-18

$85 out the door from the egg. All I could find was 9200 though, the reviews said it would do 1200, so we'll see. Get me off that 1:1 divider. At half the price of the tridents 9600 or the PI 9600, I'll be happy with stock speed @ 1150.

IIRC same chips as the tridents. Elpida (sp) I think

Just to reiterate my above question (last page) ... Do you guys think I have a chance of getting 4400mhz stable out of my 1.250 VID q9650???

[TopFuel1471]

So what is the go-to stepping for these?

[Hoss331]

theres only one, E0

[TooFastForYa]

Test each stick individually at 1.80/1.82, if they wont pass at there rated voltage and stock speed id rma them.

Tested both sticks in single channel with positive results. Both sticks passed >400% coverage in memtest @ 1.80vdimm/600mhz.

Screenshots:
Stick 1...


Stick 2...

[TooFastForYa]

Put both sticks in and boot using the same settings as above and get mem errors in memtest. Bumped MCH voltage up to 1.4 and get errors even faster.

Then you probably didn't find your optimal MCH Ref.

[derek0309hk]

you guys are amazing, the fatal error final results was xxxxxxx, expected xxxxxxx in prime95 is due to the temperature

i changed to a ek supreme lt and temperature droped a few degree, but i still get core 1 and 3 higher than 67 under 1.4v @ 4.4ghz

so i try lowering the vcore and as the temperature drop, it gives more successful tests in prime95

but because i am not putting enough vcore, bsod come soon

so now i changed the block, and am going to the rad's fans

i am using this

http://www.coolermaster.com/products...ate=36&id=6037

and

swiftech mcr320

the dba is actually sick, it must be louder than that

so do u have any suggestion on fan that isnt louder than this and can lower the coolant temp more?(closer to room temp)

there isnt much choices in hongkong but please still suggest and i will go looking for

thanks

I'm using scythe s-flex "g" fans on my mcr320. They're not too loud. Although I do have them on a controller so I can turn them down.

which one do u think is better? s-flex or cooler master that i am using?

[nkresho]

Well, the scythe fans have sony-made fluid bearings which will last a lot longer than the coolermasters, especially mounted flat (like on a radiator). I never have tried your fans though, so I can't really give a honest comparison.

Hi.
This is my 24/7 settings, 30 loops IBT maximum stress level stable, all aircooled, bios 1307.
Priming for 8h so far...

[OC Nub]

Testing the GSkill F2-9600CL5D-4gbpi.

[Marcio]

OC Nub,

First: Congrats on that CPU, is a monster!!!!!

Second: I just looked at your everest numbers at 4.5GHz /500FSB / 600MHz DDR2, and compared to my 4.2GHz / 467FSB / 560MHz DDR2, and it is strange that my L2 cache bandwidth in everest (its where the 2x6MB cache is) is higher? How can this be? I think we have the same setup, only I have Asus board and you have Gigabyte... Is that normal? Would care to post that everest bench at 4.2GHz / 467FSB / 560MHz DDR2 for a comparison? I sure can't clock my CPU at 4.5GHz!

tkx.
