So I've got these components:

1. Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775 Quad-Core
2. GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX
3. G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
4. CORSAIR CMPSU-550VX ATX12V V2.2 550W Power Supply 90
5. XFX PVT88GYDF4 GeForce 8800GTS (G92) 512MB 256-bit GDDR3 PCI Express 2.0 x16

and a XIGMATEK HDT-SD964 92mm Rifle CPU Cooler that's keeping my CPU at around ~35C idle, and doesn't go over ~50-51C at full.

ANYWAY, to get to my actual question- my bios is reading a RAM rated number that's equal to the actual number it's set on, and when I up the FSB, the number changes to go way above the rated speed. I read this was never good to do, but to get my CPU to over 2.4 (266 x 9), I have to raise the FSB im assuming. Is there any way to overclock this rig safely and get some decent OC speeds out of it without frying a component or two? I've read up and havent found any situations like the one I'm in, so thanks for your help =D!

BIOS reads:

CPU Clock Ratio 9x
CPU Frequency 2.40GHz (266 x 9)
CPU Host Frequency 266
Memory Frequency 800 800

Normal CPU Vcore 1.325V

You just need to set your memory bus speed to 1/2 the FSB datarate; this will result in the FSB and memory bus throughput running in a 1:1 ratio. So, for a FSB throughput of 1066MHz (266x4), set the memory bus speed to DDR2-667 (1066/2). Your DDR2-800 RAM should thus be fine for FSBs up to 1600MHz datarate.

I don't understand exactly how that makes sense, so I'll just post a picture and maybe you can tell me which numbers to change to what =), or anyone else for that matter.

PCI express form auto to 100
System memory multiplier from auto to 2. I believe for Gigabyte. 2 or .2? whatever it shows up as.
FSB to 333 atleast.

Actually thats wrong..he needs to set the ram to a 1:1 ratio. That would mean DDR2-533..
Anyway, I have a DS3R (similar BIOS). Just set the memory multiplier to 2.00. Good luck.

I have the same motherboard, cpu (same vid) and psu as yours. I am running at 3.2 g. Here are a few things i want you to do. First of all press Ctrl+F1 from the main screen. then go to the page you show me. Then do the followings.

1. Set your cpu frequency to 3.2 G ( if that is what you want to do) or any frequency you want to achieve.
2.Set your pci E frequency to 100.
3. Set your SPD to 2.
4. Set system voltage to manual.
5. Set your cpu voltage to 1.4 in bios. It will be about 1.344 in windows due to Vdroop.
6. Save and exit.

That is it. It is prime stable at 3.2 G with the above settings. It is very likely that yours will also be stable. But, it might give different results. At least, you have got some sorts of guidline. If you want to reach to 3.6 , set your net voltage to 1.5 ( i.e voltage in windows). But, i am happy with what i have got.

Also, there are a couple of settings you need to disable in second items from the main menu. If you can give me a snapshot, i can tell you what you should disable for stable oc.

Have fun.

2nd tab =)

Ok. Here are the settings:

1. set first boot device to your hard drive.
2. set C1E to disable.
3 set EIST to diable.
4.set virtualizaiton technology to disable.
5. set full screen logo to disable.
6. set int display to pci ex.
7. save and exit.

Then, run the prime test. watch the system temperature closely while running prime test. it should never exceed 71C. Mine is around 60 C after hours of prime test. If you exceed the 71 C limit, readjust your cooling solutions or reduce your vcore. In my case, i have to set it to 1.4 v in bios to get a stable system. if the system is stable , you might want to turn the item 2 on.

Good luck.

there was only a PCI and PEG option for the int display, so I set it to PEG that and ran prime after bootup. after 5 minutes my system automatically shut down and I got this error...



hard to see, but it says:

Problem was cause by an unrecoverable hardware error that cause the operating system to stop functioning.

We recommend doing the following:
1. back up all files to avoid data loss in case of a hardware failure

what are your settings. what frequency are you at now? what is your idle temperature. what is your Ram speed and settings.

I don't think that setting the initial display to PCIe would cause a hardware error.. what else did you modify?

monst0r - thanks for catching my silly arithmetic error on the FSB/2! So much for sleep-posting!

Heh, no problem. Happens to the best of us
