Further Help in Overclocking the Q6600 for Two Disabled People

[Alvin777]

Hello Overclockers friends.

The Intel Core 2 Quad Core Q6600 system is overclocked at around 2.572Ghz (from 2.4Ghz) with Aida64 stable, 286 FSB w/ 9x multiplier, RAM is only at 573Mhz DDR3 1146, the voltages are in auto but it can be maximized even more.

I'm doing my best to optimize an old, so that it's maximized, they earn faster but with little cost. It's budget PC (budget but the parts are branded), there will be a beefy cooler (Dimensions, L x W x H: 120x73x156mm) w/ 120mm fan that'll be installed (it's on stock Intel cooler that's been thoroughly cleaned). The goal is to get it stable with least a 332 FSB x 9 multiplier to take it to at least 3Ghz (from 2.4Ghz) so that the memory (4GB x 2) can go to the board maximum of DDR3 1330 (the memory is a DDR3 1600).



The parts are:



Intel Q6600 (G0 version, which is unlocked)

Asrock G41C-GS Rev. G/A 1.02

Kingston KVR16N11/4 (DDR3 1600, 4GB x 2, in Dual Channel, Flex Mode Operation enabled on the BIOS)

Enermax EG465p-VE (460w)

Crucial MX500 (w/ Momentum Cache enabled)

Intel stock cooler (will be upgraded to a HFS, w/ one fan that has the performance of the big sized Deepcool Gammaxx)

Lian Li Lancool mid-tower casing w/ two Lian Li 120mm fans (1 back exhaust, 1 front, 3-pin)

Windows 10 Pro (latest)

We have a fairly extensive guide here https://www.overclockers.com/forums...-c2q-quads-and-c2d-duals-a-guide-v1-1.515316/

to the forums.

It looks like your motherboard doesn't have an option to set the CPU's core voltage (vcore). Without being able to manually set the vcore your overclock will be limited to however far the stock CPU voltage will take the CPU frequency. You can bump the FSB 5MHz at a time, then stress test. When the stress test fails or core temps exceed 70C, back up 5MHz then stress test for a longer period of time. If it stays stable and under 70C that will be your maximum overclock.

If you had a better motherboard with adjustable vcore hitting 3.0GHz on the CPU would probably be a simple task.

Thanks. So true, I wish they (the disabled clients, I guess the budget is always going to their disability needs) had more budget for a proper overclockable board (not sure why Asrock which I think is Asus quality minus a few slots made a budget MB that implies it can do overclocking coz' you can take the FSB to 500 yet did not include a CPU voltage adjustment and seem to also imply you can take the RAM to 1333 yet it can only take a 10% overclock)- I guess it's still technically a MB that can do overclocking (but more of marketing, sadly).

By the way is there a CPU overclocking app for Windows 10 or Windows 11 (I'm upgrading to Windows 11, I saw a lot of overclocking world record holder use it, as well as very technical Youtube people) wherein you can adjust the CPU voltage like you could with GPU overclocking software (like EVGA PrecisionX or MSI Afterburner)?

Also if the voltages are set in Auto there are values grayed out on the right side. Are these values good enough to be applied to the voltage (manual mode) for more stability?

Have a great & blessed week. Thanks again in advance and advice and tips are always welcome.

The issue with the motherboard is not because it's Asrock, it is because it's a G41 chipset. An Asus G41 generally wouldn't be any better, but a G45 chipset from either maker would be much better from an overclocker's perspective. The P45 chipset is considered one of the best for overclocking lga775 quad cores, but it doesn't have onboard graphics.
The overclocking apps I've used in the past only let you change either just the FSB or only the things you can change in BIOS. So if there's not BIOS control of the vcore, there will be no software control either.
With the FSB staying below 333MHz there should be no need to adjust greyed out values. The only exception might be RAM voltage if you decide to play with dividers or timings. You might be able to manually run 9-9-9 instead of 11-11-11 timings. It can be very time consuming to get the RAM completely stable for the clients though. And I think stable is probably more important than speed for them.
Is the SSD set to ACHI mode BIOS vs default IDE mode? That can make a bigger difference in the 'feel of speed' more so than CPU clock.

If you're in the US or close give me a PM, I'm out if I have to ship across water. I've a Giga GA-EP45T-UD3LR that fell a little short FSB wise for my hopes.

Don't see mention of a VGA, so assuming board has onboard? Have a HD 8570, has a low-profile bracket so will need to be replaced for case use.
