780i, Q6600 Overclocking questions

post #1 of 5
Thread Starter 
Hello, first time poster. Anyway...I had a question on overclocking for my new system.

CAS: Apevia X-Jupiter Jr. 420 Watts Case (G Type Black Color with Side-Window)
CPU: (Quad-Core)Intel® Core™ 2 Quad Q6600 @ 2.4GHz 1066FSB 8MB L2 Cache 64-bit
FAN: Thermaltake V1 Gaming CPU Cooling Fan (Excellent Overclocking + Silent Proof + Smart CPU & System Thermal Monitor)
PRO_WIRING: Professional Wiring for All WIRINGs Inside The System Chasis with High Performance Thermal Compound on CPU
CS_FAN: Extra 3-Color Neon Light LED Case Fan (2 x Fans)
MOTHERBOARD: (3-Way SLI & QX9650 Support) EVGA nForce 780i SLI Mainboard FSB1333 DDR2 3 x PCIe x16 SATA RAID w/ USB2.0,IEEE1394,&7.1Audio
MEMORY: (Req.DDR2 MainBoard)3GB (3x1GB) PC6400 DDR2/800 Memory (Mushkin or Major Brand)
OS: Microsoft® Windows Vista Home Premium w/ Service Pack 1 (64-bit Edition)
POWERSUPPLY: 700 Watts Power Supplies (Thermaltake Toughpower 700W Power Supply - Quad SLI Ready)
VIDEO: NVIDIA GeForce 8800 GT 1GB 16X PCI Express (EVGA Powered by NVIDIA )

My questions:
1.) Does the setup look good in terms of compatability and cooling potential?
2.) What is burn-in time and is it a myth?
3.) I wan't this comp to last me at least 3+ years so should I stay away from OCin?
4.) I was thinking of overclocking to 3.2GHz max maybe only 3.0GHz are these stable levels that will not shorten the lifespan of my hardware?
5.) If I'm only looking at "mild" overclocking and using the link & sync method do I even need to worry about changing voltages?
6.) I heard it was possible to save up to 3 OC "templates" i.e. 1.stock 2.mild OC 3. High OC. Is that correct? If so should I only look at "initalizing" my OC settings when I need more power for a game and run stock any other time?
7.) Is the PSU high enough Watts for OCin? If so will it still be if I go SLI mode with another GPU?
8.) How should I step up my QDR by 100MHz then test for a couple hours or how fast is safe?

Thanks all for the help with this...I have been reading alot about the whole OC process and it is facinating. Any help you can provide me would be very much appreciated. /cheers

Done! I don't have the comp here yet and I can make any changes should someone see a big "hole" in my system. Thanks again!

Congratulations on the new system!

1. I think all your parts look good. Any reason you're using only 3GB of memory with the 64-bit operating system? The general rule of thumb is to use matched pairs and use either 2 or 4 of the DIMM slots on the motherboard. If you want to use three, I would go with 2x1GB and 2x512 but it 4x1GB would be just as simple to accomplish.

2. Burn in time seems to vary depending on the person you ask. I myself don't do it.

3. Overclocking WILL reduce the lifespan of the components overclocked...period. The severity of the reduction depends on the intensity of the overclock. For example, if you run your quad at FSB333x9 (3.0GHz) on stock voltages (which in almost all cases it will), you won't use the system long enough to see it fail (i.e. it will be far obsolete by then). If you ran at FSB450x9 (4.1GHz) on 1.55v, you might see the end of the road come much sooner. I think you will find 1333Mhz FSB (your motherboard reports front-side bus "quad pumped" in the BIOS) to give you a nice performance increase without affecting longevity enough for you to care.

4. 3.0 can almost certainly be had on stock voltages. 3.2 (356x9) is easy enough but you might have to raise the vCore ever so slightly. For example, I run 356x9 at 1.36v in the BIOS which equates to 1.32 after vdroop (search that word if you're unfamiliar with it)

5. Voltages must be increased exponentially to clock speed. For example, a Q6600 might need 1.35v to hit 3.2GHz but 1.55v to hit 3.5GHz. To acheive your goal, you will need to increase yours slightly if even at all. I think you will find that your motherboard will be more stable running the memory linked and synced. Linking means the memory bus speed will increase when the front-side bus is increased. Syncing means the memory bus and the front-side bus will operate at the same speed. Remember DDR2 can do two operations per clock cycle (hence the name Double Data Rate) so DDR2 800 is really running at 400Mhz.

A common combination for people pushing thier system a little harder is 400x9 (3.6GHz) and then memory at it's native 800MHz (400x2). If you're only going for 333x9(3.0GHz), you'll find that the memory, linked and syned, is only running at 667MHz. That's fine. I always link and sync memory and then try to lower latencies (search this if you're unfamiliar). There is no real benefit from setting your memory to significantly outrun the FSB (i.e. 950Mhz 4-4-4-12 is not significantly more beneficial than 800MHz 4-4-4-12)

6. The only way you can dynamically overlock (as far as I know) depending on application is through a Windows-based utility. If you take one bit of advice from my post, DO NOT USE WINDOWS-BASED UTILITIES for overclocking. You should be able to enter the BIOS, change the FSB from 1066 to 1333 and achieve the mild overclock you're looking for.

7. Yes your power supply is more than adequate for what you are doing.

8. For the Q6600, I think you can go right from 2.4GHz to 3.0GHz without testing anything in-between. When you want to surpass 3.2, I would apply settings, test, re-apply, etc. If and when you decide to do this, refer to this 680i/780i-specific guide: http://www.evga.com/forums/tm.asp?m=222688

Right on! Thanks for all the help with my questions. In regards to the RAM issue I think I'll go with 2x1GB sticks. My question now then is...if I have 4 slots for RAM can you have 2 sets of different sticks? I have a 2GB set in my dead comp that I would like to reuse if possible. It is older RAM so the specks will not match the new set (PC6400 800MHz). If I plan to even slightly OC the CPU I will need atleast 800MHz sticks correct? If I decided to go for 2GB now would I then have to get the exact same 2GB set later to upgrade or would I be able to use different value sets i.e. 2x2GB sticks? Thanks again for all the help MNiceGuy!
