Overcklocking E8500 (Core 2 Duo 3.16Ghz) on Gigabyte X48-DQ6

post #1 of 14
Thread Starter 
Hello!

I'm planning of doing some overcklocking. Will go as far as I can untill i need better cooling. But As I'm quite new on overclocking. I wanted some experts advices.

To begin with this is my specc:
Antec P182 Performance
Corsair Powersupply 750W Black,ATX/EPS
Intel Core 2 Duo E8500 3.16GHz, Socket 775
Corsair TWIN2X 6400 DDR2, 4096MB CL5, (5-5-5-18)
Gigabyte GA-X48-DQ6, X48, Socket-775
Gigabyte GeForce 9800GTX 512MB GDDR3
Western Digital Raptor 150GB SATA
Zalman CNPS9700LED Ultra Quiet CPU-Cooler
Nexus Real Silent 120mm 22.8dB Svart/Vit (Infront taking in air)

All settings in BIOS is standard, havnt changed anything yet.
Allthough I have updated BIOS to version: F6.

I can see that there is an Beta version of new BIOS: F7b
With changes: update CPU ID.

Dont really know if it's worth upgradeing. Escpecially when I want stable system for overclocking.

If more information is needed, please tell and I will add. Have a lot to learn about overclocking. Ofc I will also read around the forum and see what i can learn from that.

But in the end, In this thread I want suggestions how to config BIOS. f ex FSB increase. voltage increase etc.

Many thanks in advance!

First read the OC'ing guide
http://www.overclock.net/intel-cpus/...ing-guide.html

If you're really worried about heat, you can try manually setting all of the voltages to the default/stock values and just seeing what the hardware can handle. This is virtually risk free to the system, and sometimes results in a pretty decent overclock for starters.

After you get comfortable with the bios and get a feel for the potential of the hardware, then start tweaking the voltages.

This is my first time overclocking as well (Striker II/E8400)... It has been pretty fun so far, and real easy.

I am not framiliar with your mobo, but the E8500 should o/c very similar to E8400... very well... very easily.

w/o adjusting voltages or anything serious, I could take the e8400 from 3.0 to 3.6 w/o adjusting anything besides the FSB. This is the sweet spot.... 1:1 w/800Mhz RAM! without having to do any major tweaking or cooling.

Then, when you feel adventurous you can push 4.0+ on air!


Good Luck!

Overclocked now.
4.09 GHZ.

9,5 x 422 mhz

V-Core: 1,387
MCH: +0,250
FSB: +0,10

Started Prime95 Torture test.
After 5 minutes Temps is:

CPU: 70 celsius / 159 fahrenheit
MB: 44 celsius / 111 fahrenheit

Else idle temps is:

CPU: 42 celsius / 107 fahrenheit
MB: 44 celsius / 111 fahrenheit


My Zalman 9700 is running at 1600 RPM, else it's too loud.
So will downclock CPU now, to provide a bit cooler system.

Those settings look very close to optimum. The max vcore for the E8400 and E8500 is 1.3625v. I'd downclock to that vcore, and adjust the multi X FSB to that level. The FSB +0.1v looks good. I'd lower the MCH to +0.2v and see if it holds stable. That will help to prevent your North Bridge from overheating. Other than that. Looks perfect.

Tweaked some.

9,5 x 379 = 3600 Mhz

FSB: +0,10
MCH: +0,20
V-Core: 1,36250

Tested with Prime95. Also played few hours and all. Still stable and going good.

I know v-core should be lower so will test lower it and redo all tests.
Will update when I got more info.

seriously it would be some sort of horrible sin to have that rig(minus the crap ram) only clocked to 3.6, my 8500 did 4.7 and i wouldnt have thought to run it at less than 4.3ghz

I have heard that the Zalman 9700 wont fit on the gigabyte dq6 MB unles you remove then FSB cooling, correct ?!

Did you up your voltage along with the fsb testing in increments, or did you just set the volts to that high and see what it can do? For me, to get 3.6GHz on my E8400, I didn't have to change the stock volt at all, still at 1.225. In fact, the only volt I did change to get 3.6GHz is my RAM but that is for the 4-4-4-12 timings. I would suggest starting at stock, what does your mobo set it for stock, and see what OC you can get from that. Then raise your volts, in slow increments, and slowly increase the FSB after volt increase to see where it is stable, then repeat until you are happy.

Hi spikarn

Look at this review Similarity that you have ( link )

I hope attention to the memory ... Let operating in the 1:1 during the overclocking ... With voltage recommended by manufacturer.

Here's my stable overclock Bios Setting with x38-dq6 mobo and e8500 cpu ..


regards
